Some people think that the automobile has improved modern life. Others think that the automobile has caused serious problems. What is your opinion? Use specific reasons and examples to support your answer.

有些人认为汽车改进了生活，另外有些人认为汽车产生了严重的问题你的观点如何？1 汽车是主要的空气污染源段落大意：汽车尾气是空气的重要污染源，会加剧温室效应，降低空气质量Automobiles are the leading cause to Americas air pollution problem. Cars release toxic emissions that damage our environment, hurting our environment by adding to the greenhouse effect, damaging air quality, and decreasing the ozone, not to mention the growing smog problems, disasters done with landfill and the effects done to our water supply, which all are connected with the greenhouse effect, ozone depletion, and air quality.。

2 温室气体的排放增加温室效应段落大意：汽车尾气会加剧温室效应，造成气温上升，生物死亡等后果Cars damage our environment by the emissions released from the combustion system of an automobile. Toxic gases weaken the atmosphere allowing for more infrared rays to enter. Having more infrared rays reflected on the Earth warms the Earth, raising the temperature, causing certain vegetation life to die off, the snow caps to melt. Carbon dioxide and carbon monoxide are two greenhouse gases that damage our Earths atmosphere. Reducing the amount of these greenhouse gases will greatly help controlling these effects.。

3 汽车尾气对于人体有健康隐患段落大意：汽车尾气所含危害人体健康成分，会对人体健康造成很大伤害Cars release 30 percent of the carbon dioxide in the earths air. Carbon dioxide is released from the tailpipe of a car and can do much damage to the human respiratory system. Every time an automobile burns a gallon of gasoline it releases 22 pounds of carbon dioxide. Carbon monoxide is also a damaging greenhouse gas. Cars account for 76 percent of the carbon monoxide in the earths air.。

4 汽车给出行带来便利段落大意：汽车为人们的交通出行提供了便利条件 Transportation plays a very important role in America. The automobile is the main form of transportation in America, connecting people from point A to point B. America is covered with roads that transport cars and people could across such areas from the islands of the Florida Keys to under the mountains of the Colorado Rockies. Cars offer fast reliable transportation, offering drivers access to anywhere with roads.。

5 政府应该鼓励公共交通发展段落大意：政府应该鼓励公共交通事业的发展Cars might be seen as a fast and free way to travel, but at whose expense. There are solutions to fix this problem, Americans can support mass transit, electric sources of transportation, or choose other forms of transportation that do not harm the environment. One day in the future we will laugh at how we would stand around and admire the deep hum of a car’s tailpipe. Not caring about how the emissions released damaged our lungs, and environment. Massive change must be addressed, reducing the amount of driving time around America. This would benefit every citizen and generations to come. The creation of the automobile has dug America a deep hole. This hole can not be filled in or hidden up. This hole can and will endanger human’s life in the near future. However America can choose to stop digging this hole, we can choose to select alternatives. In hope that Mother Nature can one day replenish its goodness to the way it was meant to be.。

The 21st century has begun. What changes do you think this new century will bring? Use examples and details in your answer.

有些人认为计算机使生活更加容易方便，另外有些人认为计算机使生活更加复杂和紧张你的观点如何？Some people say that the Internet provides people with a lot of valuable information. Others think access to so much information creates problems. Which view do you agree with? Use specific reasons and examples to support your opinion.。

Overall the internet is a fast way to obtain information from a lot of different sources. It’s a good time killer if you are bored as it has billions and billions of different websites to explore. The internet is also a good way of advertising and selling and equally purchasing items. Although there are many drawbacks, the internet has more advantages than disadvantages.

2 网络的普及现状段落大意：网络在本世纪迅速普及人们利用电脑和网络可以做很多事情，例如写邮件，浏览信息等In 21st century, the Internet has become very popular around the world. Since technology has improved, many people can use the Internet at home. From the Internet, people can write or receive emails, get information from around the world, or chat with friends or other people in different countries in instant messages with clear voices and images that shorten the distance from person to person. Also, there is no time limit. One can use the Internet whenever one wants. In addition, it is very inexpensive, so it is a very convenient type of media. However, some companies or people set up a lot of traps through websites, emails, or instant messaging to advertise their erotic business or to commit crimes, so we have to be careful.。

3 网络能够提供信息和娱乐资源段落大意：人们利用网络获取各种各样的信息，进行游戏People use the internet to gather information for all sorts of things. This could be information regarding school work which is a popular category or it could be simple things like reading about a film review. They used the internet prior to interview and used it for e-mailing. People also make use of the internet by gathering information about travel and accommodation and to order or cancel tickets for various events.

4 网络信息过度公开的弊端段落大意：网络信息过度公开，面对着对私人信息保密责任的挑战 The Internet is the world’s largest international computer network. It allows users to access substantial amounts of information held at various locations all over the world, and it has challenged the organization of obligations and the responsibilities with respect to the processing of personal data.。

5 网络道德缺失的现状段落大意：网络虽然在商业，教育等领域起着重要作用，但是网络的道德体系存在问题No one denies that the Internet is the most useful tool for research, business, and education, yet the Internet is the subject of a topic that is as controversial as the legalities of abortion or homosexual rights. Many racy, illegal, and controversial materials are available on the Internet such as pornography and pirated software; on the other hand, many educational tools are on-line as well. This brings a need for a case of ethics in the Internet realm.。

6 个人自由的质疑段落大意：在网络上个人表达的自由，受到严重质疑The Internet is a carrier of a vast array of information. It provides people all over the world with the opportunity to publish their thoughts, opinions, and virtually any type of information. At the same time, it allows information to be accessed by anyone with a computer worldwide. This has caused ongoing debate regarding the freedom of expression.。

7 网络的社会危害段落大意：网络上很多信息会对社会造成损害There is a large amount of information on the Internet that is harmful and found to be socially unacceptable. This type of harmful information can lead to criminal activity, thus becoming a threat to our society. For example, the instructions on how to build a bomb are readily available on the Internet. Some people who view this may be influenced to build the bomb. This could lead to the terrorism.。

Do you agree or disagree with the following statement? Telephones and email have made communication between people less personal. Use specific reasons and examples to support your opinion.

电话和E-MAIL是人们之间的交流变的更加没有人情味，同意与否？1 电话为人们生活带来好处段落大意：电话的发明是很伟大的事情The modern telephone is the result of work done by many people, all worthy of recognition of their contributions to the field. Alexander Graham Bell was the first to patent the telephone, an "apparatus for transmitting vocal or other sounds telegraphically" after experimenting with many primitive sound transmitters and receivers. However, the history of the invention of the telephone is a confusing mass of claims and counterclaims, further worsened by lawsuits which attempted to resolve the patent claims of several individuals.。

2 电话的出现极大的改善了人们的沟通情况Three, maybe four times in recent history, a new technology has been introduced that has fundamentally transformed human society by changing the way people communicate with each other. For the most part, the moment in which these new technologies came into being are preserved with a kind of clarity and drama that is both thrilling and unforgettable.。

3 电子邮件普及的现状段落大意：电子邮件在人们之间广泛普及，人们利用电子邮件交流，便利，快捷 E-mail is short for electronic mail. E-mail is not only for fun but plays a large part in effective communication between major businesses. Almost everybody connected on the internet has an e-mail account. E-mail is not only a useful way to send text messages to other computers almost instantaneously, but you can add attachments.。

4 电子邮件的出现前所未有的改变了人们的交流方式"A surprising aspect of the message service is the unplanned, unanticipated, and unsupported nature of its birth and early growth," reads a report on e-mail written for ARPA in 1976. "It just happened, and its early history has seemed more like the discovery of a natural phenomenon than the deliberate development of a new technology." One reason that it was adopted so quickly was that it perfectly suited the communications needs and style of the engineers who built the electronic way of communication.。

5 电子邮件飞速的普及是时代的一大特征We in the ARPA community (and no doubt many others outside it) have come to realize that we have in our hands something very big, and possibly very important. It is now plain to all of us that message service over computer networks has enormous potential for changing the way communication is done in all sectors of our society. In 1996, for the first time, more electronic mail was sent than postal mail in the U.S. Almost from its creation, email has been the most widely used internet application, and in that respect can claim to be the most important. These same capabilities also underlie the technology of mailing lists.。

Choose one of the following transportation vehicles and explain why you think it has changed peoples lives. * Automobiles * bicycles * airplanes Use specific reasons and examples to support your answer.

选择汽车，自行车，和飞机中的一种交通工具解释为什么你认为它改变了人们的生活1 汽车的重要意义段落大意：车对人有很重要的象征作用和实际作用成年人为拥有汽车而骄傲One of the most important steps in becoming an adult is your first car. When you have a car, you don’t need to rely on other people for rides to where you want to go. The automobile has become a very important part of today’s society. It is a necessity to own or to access to a car in order to keep up with all of the competition of the business world, and also one’s social demands.。

2 汽车对社会的影响段落大意：汽车工业对社会发展有着长远的影响汽车工业影响着人们的生活，文化，经济发展The automobile has changed the lives, culture, and economy of the people and nations that manufacture and demand them. Ever since the late 1800s when the first “modern” car was invented by Benz and Daimler in Germany, the industry has grown into a billion dollar industry affecting so many aspects of our lives. There are more than 400 million passenger cars alone on the roads today.。

3 飞机的发明历史段落大意：Orville Wright 和 Wilbur Wright发明了历史上第一架飞机 Orville Wright (1871-1948) and Wilbur Wright (1867-1912) requested a patent application for a "flying machine" nine months before their successful flight in December 1903, which Orville Wright recorded in his diary. As part of the Wright Brothers systematic practice of photographing every prototype and test of their various flying machines, they had persuaded an attendant from a nearby lifesaving station to snap Orville Wright in full flight. The craft soared to an altitude of 10 feet, traveled 120 feet, and landed 12 seconds after takeoff. After making two longer flights that day, Orville and Wilbur Wright sent this telegram to their father, instructing him to "inform press."。

4飞机的好处段落大意：飞机给人们的出行等方面带来极大的便利和好处Generally the whole world has enjoyed the benefits of the aircraft, which has increased the overall efficiency of the human race and made travelling possible and affordable for nearly all the people on this earth. Aircrafts have shrunk the size of our earth by providing the safest mode of transportation of passengers and cargo in the least possible time between two points. Aircraft have also provided us means of defending our countries and hitting back at people who attack us. Lastly, it has been put to numerous other uses - from scientific study of the natural world to warfare.。

Do you agree or disagree with the following statement? With the help of technology, students nowadays can learn more information and learn it more quickly. Use specific reasons and examples to support your answer.

有着技术的支持，现在学生更快，更多地获得信息同意与否？1 电脑互联网的好处段落大意：电脑和互联网给学生学习提供了很好的机会大部分学生可以接触到大量信息，和教授交流，对他们的学习很有好处Computer and internet have changed the world of education in innumerable ways. Most students now have access to countless sources of information. They can also talk to experts in multitudes of professions. Many students now learn to type before they learn to write in cursive.。

2 多媒体的教学作用段落大意：多媒体和互联网给学生的学习带来便利它们实现了网络教学的可能性 Some sites contain valuable tools and accessories to aid in the learning process. As well as notes and multimedia displays, they may include things like hypertext chapters. In the future, there may not even be a need for paper textbooks. The Internet has also enabled teachers to teach a class from thousands of miles away. With video conferencing, a professor in Guam can teach a class in Michigan in close to real-time. Virtually all libraries are now connected over the Internet. At Lake Superior State University you can check the catalogs of almost any library and even check out books from nearby libraries.。

3 网络和电脑对于课堂的重要作用段落大意：网络和电脑已经被带入各个课堂之中，对教师和学生都有帮助Due to the expansion of the Internet in recent years, schools and universities around the world have been incorporating more technology into their classrooms. Computers are present on college campuses, and many teachers are including them for class activities on a daily basis. With email, a teacher can be in contact with his or her students outside the classroom to discuss class work. Computers in the classroom are extremely beneficial for students, more importantly; the use of the Internet allows students easily access to abundant information.。

4 信息繁荣隐藏的弊端 段落大意：信息的繁荣带来真实性缺少保障的负面效应With so much information available, one can never be sure as to what the credentials are of the sources from which the information is coming from. Free space for WebPages is easily available at places like Tripod and Geocities. This allows anyone to put up any kind of information that they would like to know, but makes it difficult to discern fact from fiction. Any twelve year old can create a page filled with conspiracy theories about UFOs and unsuspecting people might take it as facts.。

Do you agree or disagree with the following statement? Modern technology is creating a single world culture. Use specific reasons and examples to support your opinion.

现代技术正在产生世界统一文化，同意与否？1 科技发展使得地球村出现段落大意：现代科技使得世界变得越来越小，地球村已经出现新技术使得文化，交流相互影响，趋向于统一It is evident our world is becoming a smaller place. We now have overnight delivery of packages, email communication and the ever so popular cellular communication. Globalization and increased international business can be directly attributed to mass media and mass transit. The concept of globalization sometimes approaches this change as being one which either should or will result in a complete homogenization of culture and the formation of a unified global community.。

2 科技发展使得文化趋向全球化段落大意：全球化进程包括了文化的全球化The term globalization has come into common usage since the 1980s, reflecting technological advances that have made it easier and quicker to complete international transactions including both trade and financial flows. It refers to an extension beyond national borders of the same market forces that have operated for centuries at all levels of human economic activity. Globalization can be looked at from five different aspects: economically, technologically, politically, culturally and environmentally.。

3 人们联系紧密段落大意：由于全球化进程的加快发展，人类彼此之间联系的越来越紧密People around the world are more connected to each other than ever before. Products produced in one part of a country are available to the rest of the world. It is much easier for people to travel, communicate and do business internationally. This whole phenomenon has been called globalization. Spurred on in the past by merchants, explorers, colonialists and internationalists, globalization has in more recent times been increasing rapidly due to improvements in communications, information and transport technology.。

4 科技使得全球化进程加快段落大意：科技的发展，为文化全球化奠定基础Technology has now created the possibility and even the likelihood of a global culture. The Internet, fax machines and satellites have swept away the old national cultural boundaries. Global entertainment companies now seem to shape the understandings and dreams of ordinary citizens, wherever they live. Globalization leads to better cultural unit.。

5 全球化在政治、经济、文化表现段落大意：全球化使得政治, 经济，文化三方面都产生统一Globalization is the growing interdependence of the worlds people that involves the integration of economies, technologies, and cultures (Bradshaw). It is described as the increased movement of people, knowledge and ideas, and goods and money across national borders that have led to the increased interconnectedness among the world. Globalization is often thought of in economic terms but as we know there are three major components implicated with this idea including: economics, politics, and cultures. Some associate globalization with modernization whereas, it is perceived that there is an alteration of "traditional" societies into "Western" industrial ones. This challenges us into a debate of whether or not globalization is positive or negative.。

Do you agree or disagree that progress is always good? Use specific reasons and examples to support your answer.

进步总是好的，同意与否？1 科技的进步使得很多人失业段落大意：由于技术发展，机器已经可以替代很多人力资源，这造成了大量的失业Another aspect in which progress has proven not to be good is in the need for human labor. The use of advanced computers has created a technological world, where manual labor is not needed as much as before. The computer as a precise machine without a need for social benefits or salary demands has replaced the need for working hands, leaving many without a job. It is no doubt that a lot of people around the world have lost not only their job but also their pride in what they do.。

2 科技进步促进医学发展段落大意：医学发展对人类有好处Progress in the field of medicine and engineering has decreased child mortality, increased longevity and terminal diseases disappeared. This has increased the life span.。

3技术进步拉大贫富差距段落大意：技术的进步进一步拉大贫富差距On the other hand, industrialization has widened the gap between the rich and the poor. The rich is becoming richer and the poor is becoming poorer. The rich can avail all the facilities and enjoy them but the poor cannot afford to buy all facilities and cannot enjoy them.。

What discovery in the last 100 years has been most beneficial for people in your country? Use specific reasons and examples to support your choice.

过去100年内哪种发现对你们国家的人们好处最大？1 疫苗的发现对人类的意义段落大意：疫苗的发明使得人们身体素质得到增强There are many diseases infecting children, such as the polio disease, which may lead to death. Scientists found a solution to this problem, by injecting a tiny sample of the virus into the childs blood, in order to stimulate the immune system to fight the disease if the child catches it, which is known as vaccination.。

2 抗生素的发现对人类的意义段落大意：抗生素的发现，使得人们在基本消除了细菌带来的污染和疾病 Antibiotics have played a major role in our society thanks to Sir Alexander Flemings careful observations in 1928. Without it, many lives would be in danger due to infectious diseases. Antibiotics are chemical substances produced by various species of microorganisms and other living systems that are capable in small concentrations of inhibiting the growth of or killing bacteria and other microorganisms. These organisms can be bacteria, viruses, fungi, or animals called protozoa. A particular group of these agents is made up of drugs called antibiotics, from the Greek word anti ("against") and bios ("life"). Some antibiotics are produced from living organisms such as bacteria, fungi, and molds. Others are wholly or in part synthetic - that is, produced artificially. Penicillin is perhaps the best known antibiotic. Its discovery and later development is among mankinds greatest achievements. Antibiotics have enabled the medical profession to treat effectively many infectious diseases, including some that were once life-threaten diseases.。

The 21st century has begun. What changes do you think this new century will bring? Use examples and details in your answer.

21世纪开始了，你认为新世纪会有什么变化？1 环境问题被重视和改善段落大意：人类行为已经给环境带来很大伤害，幸运的是这些问题通过人类的努力，可以得到缓解或者解决Since the earliest days, the human race has sought to bend the natural environment to its will; since the first Man cut the first branch from a tree, a battle has been fought between mankind and Mother Nature. Rivers have been dammed, forests cleared away and mountains leveled in our quest to mould the environment to our needs. Our blinkered onslaught against the planet reached a terrible peak in the middle of the last century. Since then we have begun to realize the damage that has been done in the name of progress and civilization, but it was too late. Countless species of flora and fauna have been wiped from the face of the planet never to be seen again. Vast areas of once lush vegetation have been turned to dust. Fortunately all the problems people have thrown light on can be reverse by the hand of people.。

2 政府在改善环境方面的努力段落大意：政府在改善环境问题方面期盼会有更大的努力Environment can be defined as the natural features of our surroundings such as plant and animal life and their habitats, water, soils and the atmosphere. The impact of people on their environment can be devastating. This is where the respective role of governments can make decisions that shape environmental policy and responsibilities. These governments can be broken up into four different levels: local, state, federal and international.。

3 言论自由更加被保障段落大意：言论自由得以保障With the First Amendment states, we as Americans are given numerous freedoms. These freedoms become a constitutional right which no one can take away from us. Among these rights are the freedom of speech and freedom of the press. Many people feel that with these two freedoms combined they can post on the Internet whatever they want. However, the First Amendment does have limitations. Contrary to what some people may believe, our freedom of speech is not protected when it comes to indecency. This fact, along with several other reasons, is why cyber-pornography should no longer be present on the Internet.。

4 网络审查更加严格段落大意：网络被证明是很好的教育资源，但是为了普及网络，网络内容必须经过审查For many people, using the Internet has become practically a new way of life, especially for college students and the like. Various types of information can be accessed at the touch of a button: anything from encyclopedias, to surveys and essays, to articles from magazines, and adult sites. Anyone who pays for their Internet service is usually offered the opportunity to surf in the internet. But what would be resulted from this freedom to children? If adults can access this information with such ease, what’s stopping kids from checking it out too? Who decides what’s appropriate for kids and what’s not when their parents aren’t constantly leaning over their shoulders? And what about posting things that may be off ethic? In this case, too many people are calling for internet censorship.。

Do you agree or disagree with the following statement? Technology has made the world a better place to live. Use specific reasons and examples to support your opinion.

技术使得这个世界更加适合居住，同意与否？1 技术使得世界越来越小段落大意：全球化趋势在技术发展的支持下，将世界变得越来越小电子邮件和视频电话等新兴技术，使得人们的交流和商品、资金的流动变得容易Globalization and increased international business can be directly attributed to mass media and mass transit. With new technologies such as videophone, Internet chat and Internet meeting rooms the thought of globalization becomes a reality for even the smallest of companies. The concept of globalization sometimes approaches this change as being one which either should or will result in a complete homogenization of culture and the formation of a unified global community.。

2 全球化消除了国家间的界限段落大意：全球化进程弱化了国家间界限，提高生活水平，增加国际贸易的好处“Global integration is shrinking time, shrinking space and eroding national boundaries.” Globalization is possibly the most important force describing the process of increasing integration and interdependence between national economies. It depicts the breaking down of national boundaries leading to the establishment of a single world market. This inevitable process of globalization will continue to be accelerated by the electronic revolution. Advancement in telecommunications and information technology has lead to growth in cross border relationships initiated by the drivers of globalization. Embracing globalization is encouraged due to its explicit benefits including reducing poverty, increasing living standards and increasing world trade. These advantages must be weighed against the negative impacts of loss of environmental quality, dominance of transnational corporations and exploitation of labor.。

3 经济和科技上的发展使得全球化进程加快段落大意：经济和科技的发展，使得资金的流通，人们的交流越来越容易Economically, globalization has been greatly encouraged since the Second World War, with the introduction of free trade agreements. Additionally, regional trade agreements have also been developed, which have included single markets established by the European Community and NAFTA (North American Free Trade Agreement). Technologically, the Information Technology revolution has resulted in massive improvements in communication, through faxes, email, and the internet. These improvements have resulted in the world becoming a smaller place as world-wide interaction is both quick and easy.。

４技术发展带来环境问题段落大意：技术的发展带来了严重的环境问题Environmentally problems are increasingly becoming global problems. Therefore, countries are no longer able to look at environmental issues in isolation. This has been dramatically illustrated for example by the nuclear disaster at Chernobyl, the depletion of the ozone layer and acid rain over Scandinavia. Countries now need to act collectively to reverse the situation.。

When you write your answer, you are not limited to the examples listed in the question. It is generally agreed that society benefits from the work of its members. Compare the contributions of artists to society with the contributions of scientists to society. Which type of contribution do you think is valued more by your society? Give specific reasons to support your answer.

艺术家还是科学家对社会贡献大？1 艺术和科学的相似性段落大意：艺术和科学并不是互相割裂的科学在特殊中找普遍，而艺术旨在抓住特殊，启蒙大众Throughout the history of man, art has been a method for communication, and in the process it has alternatively shocked and soothed the world. Similarly, science has also disturbed and reassured the society. This much is evident through an evaluation of both studies. Science can be seen as the study of what is held in common between many particular instances. Art, among other things, is an attempt to capture the specific, and thus illuminate the general.。

2 科学和艺术人们都需要段落大意：人们需要科学和艺术双方，科学和艺术的平衡才是人们学习的方向One needs both art and science to be fulfilled. If we see a play, the lighting is manipulated and the props are measured and cut to a certain size. In music there is rhythm and time. In architecture there is measurement and surveying. If art is focused upon more than science or science is focused upon more than art there will not be an equal balance of appreciation between the two fields. There is no art without science. There is no song without pitch and tone and volume. There is no theater without costumes and measurements and carefully designed sets. Art and science should be equally appreciated because each has a great deal to offer.。

3 艺术和科学在现实中的并存段落大意：艺术和科学并不是互相割裂存在，任何事物都有其科学和艺术双面性Art is not only part of society, but is the product of the beliefs and values of the artist and the audience. I believe that the world is divided in the same manner as the human brain. There are both scientific side and artistic side. Everything in the world can be placed in at least one of the two categories. Furthermore, I believe that neither side is dominant over the other.。

4 科学的积极作用段落大意：科学，技术的进步，为人类生活带来无限好处Technology is knowledge of using tools and machines to do tasks more efficiently. We use technology to control the world we live in. Science and Technology are making advances at an astonishing rate. From telephones to the Internet, calculators to computers, cars to rockets and satellites, we are part of a new world of discoveries and inventions made possible by Science. Fields like Medicine and communications have changed our cultures and our lifestyles.。

If you could invent something new, what product would you develop? Use specific details to explain why this invention is needed.

如果可能，你会发明一样什么东西？1. 发明节能设备，例如绿色高效节能灯---保护环境Changing the world starts with simple actions. When you replace light bulbs or entire light fixtures in your home with ones that have earned the government’s ENERGY STAR, you help preserve energy resources and reduce the risks of global warming while saving money and time buying and changing lights in your home.

To save the most energy and money, replace your highest used fixtures or the light bulbs in them with energy-efficient models. The five highest use fixtures in a home are typically the kitchen ceiling lights, the living or family room table and floor lamps, and outdoor porch or post lamp. ENERGY STAR qualified lighting fixtures and replacement bulbs can be found at home improvement and hardware stores, lighting showrooms, and other retail stores, including on-line outlets. Find a retailer in your area with our Find a Store feature.

The smallest things can add up to a real difference. We encourage you to change out the light fixtures or bulbs at home that you use most with ENERGY STAR qualified models. If every American home replaced their 5 most frequently used light fixtures or the bulbs in them with ones that have earned the ENERGY STAR, we would save close to $8 billion each year in energy costs, and together we would prevent the greenhouse gases equivalent to the emissions from nearly 10 million cars.

2. Invention改善人们生活人类生活被每一个人类的Invention所不断优化，改善着From new modern-day conveniences like computers, cell phones and MP3 players, to the little things that we take for granted every day like electricity, running water, automobiles, telephones and airplanes, the world has evolved into what we know today thanks to the art of invention.

3. Invention的定义Defined as the process of discovering or presenting an element of novelty that will be of use to someone or something, inventing has been continuously occurring for centuries. An invention may be based on an earlier idea or collaboration, or may be en entirely new breakthrough alltogether.

4. 一些重要的Invention的实例和意义Some of the greatest inventors of all time, including Thomas Edison, Benjamin Franklin, Alexander Graham Bell, George Eastman, Steve Jobs and the Wright brothers, all had one thing in common: they wanted to make life a little easier and more convenient for the rest of us.

An invention is essentially just a good idea that serves a purpose. The only goal an invention has to accomplish is solving some kind of problem. Whether it’s making it easier for wheelchair-bound individuals to get around, or the scientific discovery of a new medical vaccine, every invention fits into its own significant role in society.

5. 富兰克林的很多奇思妙想的发明创意，提供给大家作为写这个题目的素材Some of Ben Franklins Quirkiest IdeasThe glass armonicaFranklin loved music, playing and composing it himself. On one of many trips he would take to England he saw a performer play a tune by stroking the rims of water glasses, each a different size and filled with varying amounts of liquid. Intrigued by the concept, Franklin set about creating a more structured version of the rim trick. With a glassmakers help, the armonica was born. A wooden stand propped up 37 glass hemispheres on a rotating rod, which Franklin ran moistened fingers along to produce a variety of notes depending on the thickness of the glass. Both Mozart and Beethoven would eventually compose classical pieces specifically intended for the instrument.

Swim finsAn avid swimmer, Franklin was drawn to water at a young age and consistently promoted the healthy benefits of the exercise in his later writings. At the ripe old age of 11 he invented a pair of fins that, unlike todays modern flippers, were strapped to the swimmers hands to help make each stroke more efficient. His contributions to the sport led to his posthumous induction into the International Swimming Hall of Fame.

The library chair & extension armSpending an inordinate amount of time among the stacks at the library he founded in Philadelphia, Franklin was inclined to improve the simple devices he used while enjoying his books. First, he converted a regular library chair into a multi-functional appliance that could be sat on or used as a small ladder. For those books still out of reach, Franklin devised an extendable "arm" with fingers that opened and closed by pull cord.
