There’s no doubt that nanotechnology promises so much for civilization. However, all new technologies have their teething problems, And with nanotechnology, society often gets the wrong idea about its capabilities. Numerous science-fiction books and movies have raised people’s fears about nanotechnology ---with scenarios such as inserting little nano-robots into your body that monitor everything you do without you realizing it,or self-replicating nano-robots that eventually take over the world.
So how do we safeguard such a potentially powerful technology? Some scientists recommend that nano-particles be treated as new chemicals with separate safety tests and clear labelling. They believe that greater care should also be taken with nano-particles in laboratories and factories. Others have called for a withdrawal of new nano products such as cosmetics and a temporary halt to many kinds of nanotech research.
But as far as I’m concerned there’s a need to plough ahead with the discoveries and applications of nanotechnology.I really believe that most scientists would welcome a way to guard against unethical uses of such technology. We can’t go around thinking that all innovation is bad.all advancement is bad. As with the debate about any new technology.it is how you use it that’s important.So let’s look at some of its possible uses.
Thanks to nanotechnology, there could be a major breakthrough in the field of transportation with the production of more durable metals. These could be virtually unbreakable, lighter and much more pliable leading to planes that are 50 times lighter than at present. Those same improved capabilities will dramatically reduce the cost of traveling into space making it more accessible to ordinary people and opening up a totally new holiday destination.
In terms of technology, the computer industry will be able to shrink computer parts down to minute sizes. We need nanotechnology in order to create a new generation of computers that will work even faster and will have a million times more memory but will be about the size of a sugar cube. Nanotechnology could also revolutionise the way that we generate power .The cost of solar cells will be drastically reduced so harnessing this energy will be far more economical than at present.

Science Fiction
1 Amongst the most popular books being written today are those which are usually classified as science fiction.Hundreds of titles are published every year and are read by all kinds of people.Furthermore,some of the most successful films of recent years have been based on science fiction stories.
2 It is often thought that science fiction is a fairly new development in literature,but its ancestors can be found in books written hundreds of years ago.These books were often concerned with the presentation of some form of ideal society,a theme which is still often found in modern stories.
3 Most of the classics of science fiction,however,have been written within the last hundred years. Books by writers such as Jules Verne and H.G.Wells,to mention just two well-known authors,have been translated into many languages.
4 Modern science fiction writers don ' t write about men from Mars（火星）or space adventure stories. They are more interested in predicting the results of technical developments on society and the human mind; or in imagining future worlds which are a reflection of the world which we live in now.Because of this,their writing has obvious political undertones（含义）.
5 In an age where science fact frequently overtakes（超过）science fiction , the writers may find it difficult to keep ahead of scientific advances.Those who are sufficiently clear-sighted to see the way we are going,however,may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology.The writers find it difficult______.
A:concerned with the problems to solve in the future
B:to keep ahead of scientific advances
C:have political implication
D:a current theme
E:read worldwide
F:a reciirrent theme答案：B解析：第二段第一句提到，人们常认为科幻小说是文学中的新生产物，然而在几百年前所写的书中就能发现科幻小说的踪迹了。紧接着对这些书的内容进行了简单介绍。由此可知，第二段主要讲的是科幻小说的开端。
第三段第一句就提到“Most of the classics of science fiction …"，紧接着又以两个著名的科幻小说家的例子进行说明，可知本段主要讲的是科幻小说中的经典之作。根据线索词“clas-sics of science fiction”也可知C项正确。
第四段主要讲的是，现代科幻小说家不再写火星人或宇宙冒险，而是写他们对科技发展等的预测或是对未来世界的设想，并且这些作品常带有政治含义。这些都是现代科幻小说的主题。
第五段的第一句是主题句，主要表明现代科技发展迅速，甚至超越了某些科幻小说，所以作家发现很难赶在科技发展前面。根据线索词“difficult to keep ahead of scientific advances"也可知D项正确。
由第二段第二句可知，理想社会这个主题不仅在数百年前的著作中出现过，也在现代科幻小说中出现。由此可知，这个主题是一个反复出现的主题。recurrent反复发生的，是“stilloften found”的同义转换。
根据第三段第二句可知，Jules Verne与H.G.Wells写的科幻小说被翻译成了多国语言。由此可知，Jules Verne写的科幻小说在全世界都有人读。
由第四段最后一句可知，现代科幻小说有明显的政治含义。implication是undertone的同义转换，有“含义，暗示”的意思。
由第五段第一句可知，现实中的科技发展超越了某些科幻小说，以至于很多作家感到很难赶在科技发展的前面。 -

A Good Idea
No satisfactory way exists to explain how to form a good idea. You think about a problem until you're tired,forget it,maybe sleep on it,and then flash!
When you aren't thinking about it,suddenly the answer arrives as a gift from the gods.Of course,all ideas don't occur like that but so many do,particularly the most important ones. They burst into the mind,glowing with the heat of creation.How they do it is a mystery,but they must come from somewhere.
Let's assume they come from the"unconscious".This is reasonable,for psychologists use this term to describe mental processes,which are unknown to the individual.Creative thought depends on what was unknown becoming known.
All of us have experienced this sudden arrival of a new idea,but it is easiest to examine it in the great creative personalities,many of whom experienced it in an intensified form and have written it down in their life stories and letters.
One can draw examples from genius in any field,from religion,philosophy,and literature to art and music,even in mathematics,science,and technical invention,although these are often thought to depend only on logic and experiment.All truly creative activities depend in some degree on these signals from the unconscious,and the more highly insightful the person,the sharper and more dramatic the signals become.A good idea often comes to us out of expectation.
A:Right
B:Wrong
C:Not mentioned答案：A解析：文章第一句话告诉我们现在还没有令人满意的方式解释奇思妙想的来源。因此本句的表述是错误的。
文章第二段讲到：当你不去想它的时候，答案却突然从天而降，仿佛上苍赐予你的一份礼物。当然，并非所有的思想都是这样产生的。由此我们可以判断该句的表述是正确的。
依据文章第三段，“心理学家就是用这一术语（潜意识）来描述不为人知的思维过程”可知，本句的表述是正确的。
文章第四段第一句提到：我们都有过灵机一动、突然有了一个新想法的经历，而这在那些富有创造性的天才人物身上最显而易见。因此该句的表述是错误的。
文章第四段“…the great creative personalities...written it down in their life stories and letters”的the great creative personalities是指富有创造性的天才人物，其中包括各个领域的人才。因此本句的表述是错误的。
从第五段第一句我们知道，本句的表述是正确的。
文章最后一句只是说，一个人洞察力越强，这些（潜意识）信号就越鲜明、越引人注目，但是并没有提到是否只有洞察力强的人有这些信号，因此本句文章中没有提到。 -

Generation Gap
A few years ago,it was fashionable to speak of a generation gap,a division between young people and
their elders.Parents complained that children did not show them proper respect and obedience,while children
complained that their parents did not understand them at all.What had gone wrong?Why had the generation
gap suddenly appeared?Actually,the generation gap has been around for a long time.Many critics argue
that it is built into the fabric of our society.
One important cause of the generation gap is the opportunity that young people have to choose their own
life styles.In more traditional societies,when children grow up,they are expected to live in the same area
as their parents,to marry people that their parents know and approve of,and often to continue the family occupation.
In our society,young people often travel great distances for their education,most out of the family home at
an early age,marry or live or choose occupations different from those of their parents.
In our upwardly mobile society,parents often expect their children to do better than they did: to find
better jobs,to make more money,and to do all the things that they were unable to do.Often,however,the
ambitions that parents have for their children are another cause of the division between them.Often they dis-
cover that they have very little in common with each other.
Finally,the speed at which changes take place in our society is another cause of the gap between the
generations.In a traditional culture,elderly people are valued for their wisdom,but in our society the
knowledge of a lifetime may become obsolete overnight.
The young and the old seem to live in two very different worlds,separated by different skills and abilities.
No doubt,the generation gap will continue to be a feature of American life for some time to come.Its causes
are rooted in the freedoms and opportunities of our society,and in the rapid pace at which society changes.The main idea of the first paragraph is that________.
A:the generation gap suddenly appeared
B:the generation gap is a feature of American life
C:how people can bridge the generation gap
D:many critics argue over the nature of the generation gap答案：B解析：由文章第一段最后一句话“Many critics argue that it is built into the fabric of our society", 可知很多评论家认为代沟问题是美国社会的组成部分。故选B。
around的意思是“围绕；在……附近”，在文章中是指代沟问题已经存在了一段时间，故选D。
文章中提到三个原因。由第二段第一句话，可知选项A年轻人喜欢选择他们自己的生活方式是代沟形成的原囚之一。由文章第三段第一句话，可知选项C父母对子女的高期望也是代沟形成的原因之一。由文章第四段第一句话，可知选项B美国社会的快速发展是代沟形成的原因之一。故选D。
由文章倒数第二段“The young and the old seeni to live in two very different worlds, separa-ted by different skills and abilities"，可知年轻人和老年人由于技术和能力的不同被分隔在两个不同的世界里。故选D。
文章中没有提到代沟问题该如何解决，仅仅提到代沟形成的原因，所以可以排除A、B、 D。 C项说代沟问题在某种程度上说是由老一代造成的，是正确的。 -

第9题：
问答题Practice 3 The shotgun marriage of chemistry and engineering called “Nanotechnology” is ushering in the era of serf-replicating machinery and serf-assembling consumer goods made from cheap raw atoms. Nanotechnology is molecular manufacturing or, more simply, building things one atom or molecule at a time with programmed baroscopic robot arms. A nanometer is one billionth of a meter (3-4 atoms wide). Utilizing the well understood chemical properties of atoms and molecules (how they “stick” together), nanotechnology proposes the construction of novel molecular devices possessing extraordinary properties. The trick is to manipulate atoms individually and place them exactly where needed to produce the desired structure. This ability is almost in our grasp. The anticipated payoff for mastering this technology is far beyond any human accomplishment so far. By treating atoms as discrete, bit-like objects, molecular manufacturing will bring a digital revolution to the production of material objects. Working at the resolution limit of matter, it will enable the ultimate in miniaturization and performance. By starting with cheap, abundant components-molecules-and processing them with small, high-frequency, high-productivity machines, it will make products inexpensive. Design computers that each executes more instructions per second than all of the semiconductor CPUs in the world combined. Nanotechnology will reverse the harm done by the industrial revolution. Imagine being able to cure cancer by drinking a medicine stirred into your favorite fruit juice. Imagine a supercomputer no bigger than a human cell Imagine a four-person, surface-to-orbit spacecraft no larger or more expensive than the family car. These are just a few products expected from nanotechnology. Humanity will be faced with a powerful, accelerated social revolution as a result of nanotechnology. In the near future, a team of scientists will succeed in constructing the first nano-sized robot capable of self-replication. Within a few short years, and five billion trillion nano-robots later, virtually all present industrial processes will be obsolete as well as our contemporary concept of labor. Consumer goods will become plentiful, inexpensive, smart, and durable. Medicine will take a quantum leap forward, space travel and colonization will become safe and affordable. For these and other reasons, global life styles will change radically and human behavior will be drastically impacted. The world is on the brink of a new technological revolution beyond any human experience. A new, more powerful industrial revolution capable of bringing wealth, health, and education, without pollution, to every person on the planet. No longer will forest need to be cut or smoke spewed into the air. This is the promise of nanotechnology. A nanometer is one billionth of a meter. That’s a thousand, million times smaller than a meter. If you blew up a baseball to the size of the earth, the atoms would become visible, about the size of grapes. Some 3-4 atoms fit lined up inside a nanometer.正确答案： 参考译文
化学与工程学之间的“拉郎配”(即“纳米技术”)正在开创一个自行复制机制的时代,一个利用很容易得到的天然原子自行“装配”生活消费品的时代。
纳米技术即分子制造业,简言之,就是运用程控毫微机器手,一个原子一个原子(或分子)地“建”造东西。一纳米即十亿分之一米(可以排列三四个原子)。
利用人们熟知的原子和分子的化学特性(如原子和分子是如何“粘”在一起的),纳米技术令具有非凡特性的新颖的分子构成物的问世成为可能。其技术在于一个一个地操纵原子,将原子准确地置于所需的位置,以得到理想的物质结构。这种能力,人类已经基本在握。掌握纳米技术的预期回报是迄今为止人类的任何一项科技成就所不能比拟的。
把原子当作单个的、小型构件来对待,分子制造业将给物质生产带来一场数字革命。致力于对物质分解极限的研究,就能使“小型化”及其产品化推向终极。以容易获得而又大量存在的物质(分子)为原料,且以小型、高频、高产的机械进行加工,产品价格必定低廉。以纳米技术设计的计算机,每一台计算机在一秒之内处理的指令超过现在全球半导体中央处理器所能处理的指令之总和。
纳米技术将挽回工业革命所带来的损害。设想一下,治愈癌症痼疾,只须搅动一下放入药物的果汁,喝下就行了!设想一下,一台超型计算机的体积竞比一个人体细胞还要小。再设想一下,一艘由地面发向太空轨道的四座太空船,无论其体积,还是价格,都不会超过一辆家用小轿车!这些只不过是少数几种可望从纳米技术获得的产品罢了。
随着纳米技术的诞生,人类将面临一场强大的、来势迅猛的社会革命。不久的将来,一个科学家小组将成功研制出首例能进行自行复制的纳米型机器人。不需几年,当50亿万亿个纳米机器人问世之后,几乎所有现存的生产工艺将弃而不用,同时,现有的“劳动”观念也将被视为陈腐。生活消费品将丰富、价廉、智能化而且经久耐用。医学将出现巨大突破。太空旅行和向太空移民将是既安全又经济。
由于以上(及其他)原因,全球人类的生活方式将发生根本性变化,人类的行为方式也将受到巨大的影响。一场人类从未经历过的新技术革命,在我们这个世界将一触即发。一场新的、更伟大的工业革命将给我们地球上的每个人带来财富、健康和教育,而这场工业革命绝无污染。森林将免遭砍伐的厄运,烟尘将不再向蓝天吐烟,这就是纳米技术带来的前景。
一纳米为十亿分之一米,即一纳米比一米小十亿倍。假如你将一个棒球吹到有地球这么大,你就能看见原子了,其大小如葡萄。大约3到4个原子能排列在一纳米之内。解析： 暂无解析 -

There’s no doubt that nanotechnology promises so much for civilization.

Numerous science-fiction books and movies have raised people’s fears about nanotechnology ---with scenarios such as inserting little nano-robots into your body that monitor everything you do without you realizing it,or self-replicating nano-robots that eventually take over the world.
So how do we safeguard such a potentially powerful technology? Some scientists recommend that nano-particles be treated as new chemicals with separate safety tests and clear labelling. They believe that greater care should also be taken with nano-particles in laboratories and factories. Others have called for a withdrawal of new nano products such as cosmetics and a temporary halt to many kinds of nanotech research.
But as far as I’m concerned there’s a need to plough ahead with the discoveries and applications of nanotechnology.I really believe that most scientists would welcome a way to guard against unethical uses of such technology. We can’t go around thinking that all innovation is bad.all advancement is bad. As with the debate about any new technology.it is how you use it that’s important.So let’s look at some of its possible uses.
Thanks to nanotechnology, there could be a major breakthrough in the field of transportation with the production of more durable metals.

Science Fiction
1 Amongst the most popular books being written today are those which are usually classified as science fiction.Hundreds of titles are published every year and are read by all kinds of people.Furthermore,some of the most successful films of recent years have been based on science fiction stories.
2 It is often thought that science fiction is a fairly new development in literature,but its ancestors can be found in books written hundreds of years ago.These books were often concerned with the presentation of some form of ideal society,a theme which is still often found in modern stories.
3 Most of the classics of science fiction,however,have been written within the last hundred years. Books by writers such as Jules Verne and H.G.Wells,to mention just two well-known authors,have been translated into many languages.
4 Modern science fiction writers don ' t write about men from Mars（火星）or space adventure stories. They are more interested in predicting the results of technical developments on society and the human mind; or in imagining future worlds which are a reflection of the world which we live in now.Because of this,their writing has obvious political undertones（含义）.
5 In an age where science fact frequently overtakes（超过）science fiction , the writers may find it difficult to keep ahead of scientific advances.Those who are sufficiently clear-sighted to see the way we are going,however,may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology.Some form of ideal society is______.
A:concerned with the problems to solve in the future
B:to keep ahead of scientific advances
C:have political implication
D:a current theme
E:read worldwide
F:a reciirrent theme答案：F解析：第二段第一句提到，人们常认为科幻小说是文学中的新生产物，然而在几百年前所写的书中就能发现科幻小说的踪迹了。紧接着对这些书的内容进行了简单介绍。由此可知，第二段主要讲的是科幻小说的开端。
第三段第一句就提到“Most of the classics of science fiction …"，紧接着又以两个著名的科幻小说家的例子进行说明，可知本段主要讲的是科幻小说中的经典之作。根据线索词“clas-sics of science fiction”也可知C项正确。
第四段主要讲的是，现代科幻小说家不再写火星人或宇宙冒险，而是写他们对科技发展等的预测或是对未来世界的设想，并且这些作品常带有政治含义。这些都是现代科幻小说的主题。
第五段的第一句是主题句，主要表明现代科技发展迅速，甚至超越了某些科幻小说，所以作家发现很难赶在科技发展前面。根据线索词“difficult to keep ahead of scientific advances"也可知D项正确。
由第二段第二句可知，理想社会这个主题不仅在数百年前的著作中出现过，也在现代科幻小说中出现。由此可知，这个主题是一个反复出现的主题。recurrent反复发生的，是“stilloften found”的同义转换。
根据第三段第二句可知，Jules Verne与H.G.Wells写的科幻小说被翻译成了多国语言。由此可知，Jules Verne写的科幻小说在全世界都有人读。
由第四段最后一句可知，现代科幻小说有明显的政治含义。implication是undertone的同义转换，有“含义，暗示”的意思。
由第五段第一句可知，现实中的科技发展超越了某些科幻小说，以至于很多作家感到很难赶在科技发展的前面。 -
第16题：
Californian Michael Schwabe said goodbye to the gas pump two years ago．He leased an electric car．Schwabe says he gets more out of driving an electric car than just a charge.
"With the price of gasoline and with the problems with clean air,it's important we get electric vehicles out on the road."
On California roads there are about two thousand electric cars．By 2003,ten percent of all new cars may be required to have zero emissions．This is a mandate automakers say it is way ahead of its time.
Gloria Bergquist of the Alliance of Auto Manufacturers says,"The technology(for zero emissions)isn't here yet;it still needs advancement in driving range to make it more appealing to a wider consumer audience."
Auto makers blame it on the batteries．Power runs out on most cars after about 70 miles．However,some cars can now go more than 100 miles on a charge．Batteries are expensive．Carmakers say there is nothing they can do about it.
Tim Carmichael of the Clean Air Coalition says,"The automakers have not built a vehicle unless required to do so,so it's very important for the state to stay committed to this program requiting automakers to build small amounts in beginning years and then the market will take off."
Right now the California Air Resources Board requires that a percentage of new cars sold should be free of emissions．What is that percentage?A.1%．
B.5%．
C.10%．
D.100%.答案：C解析：参见第三段：加利福尼亚州要求到2003年，加州的道路上应有l0%的新车是不排放污染气体的。 -

Generation Gap A few years ago,it was fashionable to speak of a generation gap,a division between young people and their elders.Parents complained that children did not show them proper respect and obedience,while children complained that their parents did not understand them at all.
What had gone wrong?Why had the generation gap suddenly appeared?Actually,the generation gap has been around for a long time.Many critics argue that it is built into the fabric of our society.
One important cause of the generation gap is the opportunity that young people have to choose their own life styles.In more traditional societies,when children grow up,they are expected to live in the same area as their parents,to marry people that their parents know and approve of, and often to continue the family occupation.
In our society,young people often travel great distances for their education,most out of the family home at an early age,marry or live or choose occupations different from those of their parents. In our upwardly mobile society,parents often expect their children to do better than they did:to find better jobs,to make more money,and to do all the things that they were unable to do.
Often,however,the ambitions that parents have for their children are another cause of the division between them.Often they dis-cover that they have very little in common with each other. Finally,the speed at which changes take place in our society is another cause of thie gap between the generations.In a traditional culture,elderly people are valued for their wisdom,but in our society the knowledge of a lifetime may become obsolete overnight.
The young and the old seem to live in two very different worlds,separated by different skills and abilities, No doubt,the generation gap will continue to be a feature of American life for some time to come.Its causes are rooted in the freedoms and opportunities of our society,and in the rapid pace at which society changes.The word"around"in Paragraph 1 means_____＿.
A:on all sides
B:in every direction
C:near
D:in existence答案：D解析：文章第一段主要讲述了美国社会中所存在的代沟问题：父母抱怨孩子们不够尊敬和服从他们；孩子们抱怨父母不理解他们。实际上，该问题已经存在了很长一段时间。评论家认为代沟已经成为美国社会结构的一部分。由此可见，代沟是美国的一种特征。因此B为正确答案。
由文章第一段倒数第二句话可知，代沟问题已经存在了很长时间。around在此处意思是“存在”，与in existence（存在）意思相近。因此D为正确答案。
文章从三方面讲述了代沟形成的原因。由第二段第一句话可知，形成代沟的一个重要原因是年轻人必须选择自己的生活方式；由第三段第一句话可知，父母对孩子期望过高也是代沟形成的一个原因；由第四段第一句话可知，社会的快速变化也是导致代沟形成的原因。而文中并未提到现代教育使得孩子与父母想法不同的问题。因此D为正确答案。
由文章第三段最后一句话可知，父母和孩子会发现彼此之间几乎没有相似之处。因此D为正确答案。
文章主要讲的是美国社会中所存在的代沟问题及其形成的原因，并没有提到如何解决这一问题，因此排除A.B选项；而D项（美国社会应该避免代沟问题）文中也未提及.由文章第三段可知，父母对孩子期望过高也是形成代沟的原因。因此C为正确答案。 -

第23题：
问答题Advances in technology and science have solved many problems. However，they have also created new problems，among which pollution has attracted much attention of the public. Write a composition of about 400 words on the following topic，discussion the problems caused by pollution.ON POLLUTIONIn the first part of your writing you should present your thesis statement, and in the second part you should support the thesis statement with appropriate details. In the last part you should bring what you have written to a natural conclusion or a summary. Marks will be awarded for content, organization, grammar and appropriateness. Failure to follow the above instructions may result in a loss of marks.正确答案：
ON POLLUTION Nowadays we have many conveniences in our society, which have been brought through technology and science. However, these same advancements in technology and science have caused some very dangerous problems. These problems will not go away easily because people do not want to give up the conveniences of a modem lifestyle. The most critical problems that should be dealt with immediately are those of pollution.
Pollution caused by chemicals is a very serious problem because it causes the loss of the ozone layer. Without our ozone, not only we ourselves but also plant and animal life are exposed to dangerous rays from the sun. Aerosol cans emit chemicals that break down our ozone layer. Refrigeration and air-conditioning systems and ears also have dangerous emissions. A very serious threat to the planet—the warming of the earth's atmosphere—is primarily caused by carbon dioxide emissions. Many scientists think that the warming could be sufficient to melt the polar ice caps, thus raising the sea levels. This would mean that many parts of the world would be submerged below sea level.
There are other problems caused by pollution. Factories that make our modem conveniences emit poisonous gases onto the air we breathe. The chemicals we use for cleaning and wastes from factories go into our water systems and pollute the water we drink and the fish we eat. They also kill much of the wildlife we depend on for food. Some of the pesticides we have sprayed on our crops have been found to be dangerous. This kind of pollution may stay in the ground for a very long period of time.
Last but not the least, nuclear pollution will lead directly to nuclear damage. The explosions at Three Mile Island in the United States in 1979 and at Chernobyl in the Soviet Union in 1986 provided lessons to the global nuclear industry. The exposure to very high radiation levels released by nuclear plants within a short period of time may harm the environment many years, and usually will cause fatal injuries to human health.
In conclusion, the problems created by pollution are growing daily. Because people do not want to change their lifestyles, we must invent a way to neutralize the pollutants we are putting into our environment. People need to be educated so that will stop damaging the planet. Furthermore, government must take action to prevent individuals and companies from harming their environment.解析：
