Computer Literacy
There is no denying that students should learn something about how computers work,just as we expect them at least to understand that the internal-combustion engine（内燃机）has something to do with burning fuel, expanding gases and pistons（活塞）being driven. For people should have some basic idea of how the things that they use do what they do.Further,students might be helped by a course that considers the computer's impact on society. But that is not what is meant by computer literacy. For computer literacy is not a form of literacy（读写能力）。It is a trade skill that should not be taught as a liberal art.
Learning how to use a computer and learning how to program one are two distinct activities. A case might be made that the competent citizens of tomorrow should free themselves from their fear of computers.But this is quite different from saying that all ought to know how to program one. Leave that to people who have chosen programming as a career. While programming can be lots of fun,and while our society needs some people who are experts at it,the same is true of auto repair and violin-making.
Learning how to use a computer is not that difficult,and it gets easier all the time as programs become more"user-friendly".Let us assume that in the future everyone is going to have to know how to use a computer to be a competent citizen.What does the phrase"learning to use a computer" mean? It sounds like"learning to drive a car",that is,it sounds as if there is some set of definite skills that,once acquired,enable one to use a computer.
In fact,"learning to use a computer" is much more like"learning to play a game",but learning the rules of one game may not help you play a second game,whose rules may not be the same. There is no such a thing as teaching someone how to use a computer. One can only teach people to use this or that program.To be the competent citizens of tomorrow,people should_______.
A:try to lay a solid foundation in computer science
B:be aware of how the things that they use do what they do,
C:learn to use a computer by acquiring a certain set of skills
D:understand that programming a computer is more essential than repairing a car答案：C解析：题干意思为：要成为未来的称职公民，人们应该怎么做。根据文章第2段，未来的称职公民要学习一些电脑的基本技能，但不必像专业编程人员那样。因此答案C为正确选项。
题干意思为：第二段提到的“小提琴制造”是为了说明什么。举这个例子是为了说明第2段的第一句话，即学习使用电脑和学习如何编程是两件截然不同的事情。因此答案D“人们可以使用电脑并不意味着必须了解电脑编程”为正确答案。
题干意思为：学习如何使用电脑正在变得越来越容易，原因是什么。文章第3段指出Learning how to use a computer is not that difficult , and it gets easier all the time as programs become more " user-friendly"，即学习使用电脑不难，并正在变得更加容易，原因是电脑程序正变得“让用户容易使用”，因此可知B为正确选项。
题干意思为：根据作者所述，第三段中“学习使用电脑”是什么意思。这一题的答案在文章的最后一句。即没有教一个人如何使用电脑这回事，一个人只能教别人如何使用这个或那个软件。答案C为学习特定的软件，符合题意。
题干意思为：作者写这篇文章的目的是什么。文章在第一段引出了computer literacy的概念，即“电脑素养”。全篇都是在围绕这个词进行解释。 -

题干中所提到的“pocket calculators”出现在文章第一段中。根据文章第二段第一句中的“this”可知，第二段中提到的科技的负面影响应该在第一段也出现过。所以袖珍计算器对学生的影响应该是负面的，故答案为C项“对学生的思考能力有害”。 -

第13题：
Passage One
Animals have different ways of protecting themselves against wintertime weather. Some animals grow heavy coats of fur or feathers, while others dig into the ground to find a warm wintertime home.
Some animals spend the winter in a deep sleep because by going to sleep they avoid the time of the year when food is scarce and the temperatures are low. Their sleep is known as hibernation.
There is much about hibernation that puzzles scientists. For example, they are wondering how hibernation came into being. Some scientists have explored the possibility that animals release a chemical that starts them hibernating.
One thing that scientists are certain about is that animals hibernate only when it is cold. Hibernation is a seasonal practice.
Some animals that fall into a wintertime sleep are not true hibernators because they spend only a part of the cold season asleep. Bears, for example, can easily be awakened from their winter nap. They are not true hibernators.
Sometimes it is difficult to determine whether a particular animal is a true hibernator. For example, some mice hibernate, but others do not. The same is true of bats. Some of them hibernate. Others do not.
36. Hibernation is a seasonal practice. This means it ______.
A. takes place only during a particular season
B. occurs only during the night
C. is a daily practice
D. only happens when a species becomes over-populated
正确答案：A

［A］millions of web pages can be translated overnight
［B］one can find most inventions and breakthroughs online
［C］software manufacturers can lower the cost of computer parts
［D］scientists using different specialty terms can collaborate much better
正确答案：D本题考查事实细节题。题干要求选出未来网络带来的好处。第五段最后三句提到：语义万维网可以阅读并翻译专业术语，从上百万的网站提取总结相关信息；促进全球不同文化背景的人之间的合作。［D］项scientists是不同文化背景的人的一个特例，所以是正确项。
［A］项错误，因为该段第四句提到overnight时，是说语义万维网可以在一夜之间比一个人一辈子评估的知识的联合还要多，而不是翻译网页。［B］项的内容是现在的网络就能做到的，不能作为未来网络的好处。［C］项文章没有提及，文中只是说到软件代理商能帮助制造商找到成本最低的零件供应商，并和他们洽谈。

问答题Recently, the fact that more and more students are spending too much time playing computer games has aroused great concern. What influences do the computer games have on people and what should we do with them? Write a composition to give your views. You should write at least 120 words.正确答案：
Nowadays, most of the boy students are crazy about playing computer games. The parents and teachers are very concerned with this situation. Then what influences does the computer game have on the players and what should we do with it?
The computer games can give the players intellectual confidence and enhance their learning on a certain degree. However, their disadvantages are more prevailing. Most of the video games are of violent theme, which may desensitize the players to violence and alter their perception of reality. That may also give them the false idea that violence is an acceptable way to deal with problems and conflict. Meanwhile, spending too much time on video games would certainly affect their study. Concerning this, we should control children’s time spent on playing computer games and encourage them to do some other activities, such as doing sports, reading and travelling.解析： 暂无解析 -
