Passage Two
When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
People who are nearsighted can only see things that are very close to their eyes. Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly'.
People who are nearsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object out of one eye; then look at the same object out
of the other eye. You will find the object's relation to the background (背景) and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.
40. We should take good care of our eyes ______.
A. only when we cannot see perfectly
B. only when we can see well
C. even if we can see well
D. only when we realize how important our eyes are
正确答案：C40．答案为C 此考题为推理题。根据作者在第1段第2句所表达的，等到我们两眼视力下降了我们才认识到眼睛的重要性，我们就可断定C正确。

第4题：
When I opened the first "Body Shop" in 1976, what I wanted to do was to earn （挣） enough money to feed my children. Today the "Body Shop" is a great company growing fast all around the world. In the years since we began, I have learned a lot. Much of what I have learned will be found in this book, because I believe that we, as a company, have something worth saying about how to run a successful business without giving up what you really believe in.
It's not an ordinary business book. It is not just about my life, either. The message is that to succeed in business you have to be different. Business can be fun, and can be run with love and do good. In business, as in life, I need to enjoy myself, to have a feeling of my family and to feel excited by something unusual. I have always wanted the people who work for the "Body Shop" to feel the same way.
Now this book sends these ideas out into the world, and makes them public. I'd like to think there are no limits （界限） to our "family", and no limits to what can be done. I find that an exciting thought. I hope you do, too.
What kind of person does the writer seem to be?A. She is mainly interested in making money.
B. She thinks running a business a different job.
C. She seems to be successful but unhappy.
D. She seems to be someone with strong confidence.答案：D解析： -
第5题：
As adults,it seems that we are constantly pursuing happiness,often with mixed results.Yet children appear to have it down to an art-and for the most part they don't need self-help books or therapy.instead,they look after their wellbeing instinctively,and usually more effectively than we do as grownups.Perhaps it's time to learn a few lessons from them.41_What does a child do when he's sad?He cries.When he's angry?He shouts.Scared?Probably a bit of both.As we grow up,we learn to control our emotions so they are manageable and don't dictate our behaviours,which is in many ways a good thing.But too often we take this process too far and end up suppressing emotions,especially negative ones.that's about as effective as brushing dirt under a carpet and can even make us ill.What we need to do is find a way to acknowledge and express what we feel appropriately,and then-again，like children-move on.42_A couple of Christmases ago,my youngest stepdaughter,who was nine years old at the time,got a Superman T-shirt for Christmas.It cost less than a fiver but she was overjoyed,and couldn't stop talking about it.Too often we believe that a new job,bigger house or better car will be the magic silver bullet that will allow us to finally be content,but the reality is these things have very little lasting impact on our happiness levels.Instead,being grateful for small things every day is a much better way to improve wellbeing.43_Have you ever noticed how much children laugh?If we adults could indulge in a bit of silliness and giggling,we would reduce the stress hormones in our bodies,increase good hormones like endorphins,improve blood flow to our hearts and even have a greater chance of fighting off enfection.All of which,of course,have a positive effect on happiness levels.44_The problem with being a grown up is that there's an awful lot of serious stuff to deal with---work,mortgage payments,figuring out what to cook for dinner.But as adults we also have the luxury of being able to control our own diaries and it's important that we schedule in time to enjoy the things we love.Those things might be social,sporting,creative or completely random（dancing aroud the living room,anyone?）--it doesn't matter,so long as they're enjoyable,and not likely to have negative side effects,such as drinking too much alcohol or going on a wild spending spree if you're on a tight budget.45_Having said all of the above,it's important to add that we shouldn't try too hard to be happy.Scientists tell us this can backfire and actually have a negative impact on our wellbeing.As the Chinese philosopher Chuang Tzu is reported to have said:"Happiness is the absence of striving for happiness."And in that,once more,we need to look to the example of our children,to whom happiness is not a goal but a natural by product of the way they live.44选？A.Be silly
B.Have fun
C.Express your emotions
D.Don't overthink it
E.Be easily pleased
F.Notice things
G.Ask for help答案：B解析：第五段第二句提到But as adults we also have the luxury of being able to control our own diaries and it's important that we schedule in time to enjoy the things we love.即成年人有权利自己安排时间，应该给自己找时间来享受生活的乐趣，接下来又说，不管人们所选择的是什么样的事情，只要是无害的，能让人享受的，都会给人们带来幸福，因此本段的中心意思是我们要享受生 -

In a world where it seems we already have too much to do，and too many things to think about，it seems the last thing we need is something new that we have to learn.But use cases do solve a problem with requirements:with（ ）declarative equirements it's hard to describle steps and sequences of events.Use cases，stated simply，allow description of sequences of events that，taken together，lead to a system doing something useful.As simple as this sounds，this is important.When confronted only with a pile of requiements，it's often（ ）to make sense of what the authors of the requirements really wanted the system to do.In the preceding example，use cases reduce the ambiguity of the requirements by specifying exactly when and under what conditions certain behavior occurs;as such，the sequence of the behaviors can be regarded as a requirement.Use cases are particularly well suited to capture approaches.Although this may sound simple，the fact is that（ ）equirement capture approaches，with their emphasis on declarative requirements and"shall"statements，completely fail to capture the（ ）of the system's behavior.Use cases are a simple yet powerful way to express the behavior of the system in way that all stakeholders can easily understand.But，like anything，use cases come with their own problems，and as useful as they are，they can be（请作答此空）.the result is something that is as bad，if not worse，that the original problem.Therein it's important to utilize use cases effectively without creating a greater problem than the one you started with.A.misapplied
B.applied
C.used
D.powerful答案：A解析：题意想要表达的意思是任何事情一样，使用的情况下，都有他们自己的问题，他们都有可能被误用，正确答案为A，误用，滥用。附（参考翻译）：在一个似乎已经有做不完的事情的世界里，我们有大量事情要思考，似乎我们不太需要学习新的东西。但是用例解决问题是有条件的：严密的说明性需求使得描述事件的步骤和次序变得举步维艰。简单地讲，用例描述一组事件序列，系统性地执行产生相应有用的结果。听上去简单明了，这是很重要的。当面对一大堆的需求时，通常不太可能理解这些需求的发起者到底想要系统做什么。在前面的案例中，用例通过详细准确描述什么时间、什么情况下确定的行为会发生，以减少需求的不确定。像这样的一些动作序列被看作是一个需求。用例特别适合于捕捉方法。虽然这听起来很简单，但事实上不同的需求会根据他们各自在说明性需求和“应有”的声明的侧重面上捕捉方法，导致完全无法捕捉到系统行为的初衷。用例是一个所有的利益相关者都可以很容易地理解的、简单却十分有效的表达系统的行为的方式。但是，和其他任何事情一样，用例也存在自身的问题，可能会被误用而弄巧成拙。造成的后果也很糟糕，或许只是没有比原本想要解决的问题更麻烦罢了。因此有效使用用例而避免制造更大的麻烦是非常重要的。 -
第9题：
The water we drink and use is running short in the world.We all have to learn how to stop wasting our limited water.One of the steps we should take is to find ways of reusing it.Experiments have already been done in this field.
Today in most large cities,fresh water is used only once,then it runs into waste system.But it is possible to pipe the used water to a purifying factory.There it can be filtered and treated with chemicals so that it can be used again,just as it were fresh from a spring.
But even if every large city purified and reused its water,we still would not have enough.Then we could turn to the oceans.All we’d have to do to make use of the seawater on earth is to get rid of the salt.This process is called desalinization,and it is already in use in many parts of the world.
The way to stop wasting our limited water is to________.A.do experiments with water
B.purify the used water and reuse it
C.use fresh water once again
D.make use of seawater答案：B解析： -

单选题Research Is a State of Mind For many years there has been much misunderstanding as to just what research is. The popular conception seems to be that there is something mysterious about it， and before any research can be done it is necessary to have expensive scientific apparatus and large， elaborately equipped laboratories. Actually， this is not so. （6） It is a simple， organized way of trying to accomplish something you wish to do—so simple that anyone can do research anywhere at any time. First， you select the problem you would like to solve， then you list at least ten reasons why it has not been solved. （7） It takes just as much effort to solve a useless problem as a useful one. （8） After carefully—and I want to emphasize that word “carefully”—selecting the problem and the ten things between you and the solution， you then use the same procedure as in solving a crossword puzzle.（9）In the solution of the remaining obstacles you may need some simple apparatus， but the things you will probably need most are infinite patience and persistence. Few people realize the difficulties of doing any new thing. Maybe one of the reasons people are so easily discouraged is because of their education. During all our years at school we were examined two or three times a year. If we failed once， we were out. （10）If we are going to make progress， we must learn to fail intelligently so that we won't become discouraged at the 99.9 per cent failure. 6.（）AMake sure the game is worth the candle.
BThat is a step in the right direction， but I don't believe it is enough.
CYou take the easy obstacles first and by a process of elimination you eventually arrive at the one or two major ones.
DBut in selecting the problem， you need to be sure to analyze it carefully to see that it is worth the effort.
EResearch isn't a physical thing at all； it's a state of mind.
FBy contrast， all research work is 99. 9 per cent failure and， if we succeed once， we are in.

Modcm inventions have speeded up people’s lives amazingly. Motor-cars cover a bundred miles in little more than an hour. Aireraft cross the world a day, while computers operate at lightning speed.

We are so accustomed to constant activity that we find it difficult to sit and do nothing, or even just one thing at a time. Pcrhaps the days are long gone when we might listen quietly to a story on the radio, letting imavination take us into another world.

In a world where
it seems we already have too much to do, and too many things to think about, it

solve a problem with requirements:with （71） declarative requirements it's hard to describe steps and sequences of
events.
Use cases, stated
simply, allow description of sequences of events that, taken together, lead to
a system doing something useful.As simple as this sounds,this is important.
When confronted only with a pile of requiements, it's often（72）to make sense of what the authors of the
requirements really wanted the system to do.In the preceding example, use cases
reduce the ambiguity of the requirements by specifying exactly when and under
what conditions certain behavior occurs;as such, the sequence of the behaviors can
be regarded as a requirement. Use cases are particularly well suited to capture
approaches. Although this may sound simple, the fact is that （73） requirement capture approaches, with their
emphasis on declarative requirements and "shall"
statements,completely fail to capture fail to capture the （74） of the system's behavior. Use cases are a

B.applied
C.used
D.powerful答案：A解析：在这个世界上，似乎我们有太多的事情要去做，有太多的事情要去思考，那么需要做的最后一件事就是必须学习新事物。
而用例恰恰可以解决带有需求的问题：如果具有严格声明的需求，则很难描述事件的步骤和序列。
简单地说，用例可以将事件序列的说明放在一起，引导系统完成有用的任务。正如听起来一样简单---这很重要。在面对很多需求的时候，通常不太可能理解需求的作者真正想要系统做什么。在前面的例子中，通过指定特定行为发生的时间和条件，用例减少了需求的不确定性。这样的话，行为的顺序就可以当作是一种需求。用例特别适用于捕捉这类需求。尽管听起来可能很简单，但事实情况是由于常规的需求捕捉方法所侧重的是声明需求和“应该怎么样”的陈述，因此完全无法捕捉系统行为的动态方面。用例是一种简单而有效的表达系统行为的方式，使用这种方式所有参与者都很容易理解。
但是与任何事物一样，用例也存在自己的问题---在用例非常有用的同时，人们也可能误用它，结果就产生了比原来更为糟糕的问题。因此重点在于：如何有效地使用用例，而又不会产生比原来更严重的问题。 -
第21题：
Research Is a State of Mind For many years there has been much misunderstanding as to just what research is. The popular conception seems to be that there is something mysterious about it， and before any research can be done it is necessary to have expensive scientific apparatus and large， elaborately equipped laboratories. Actually， this is not so. （6） It is a simple， organized way of trying to accomplish something you wish to do—so simple that anyone can do research anywhere at any time. First， you select the problem you would like to solve， then you list at least ten reasons why it has not been solved. （7） It takes just as much effort to solve a useless problem as a useful one. （8） After carefully—and I want to emphasize that word “carefully”—selecting the problem and the ten things between you and the solution， you then use the same procedure as in solving a crossword puzzle.（9）In the solution of the remaining obstacles you may need some simple apparatus， but the things you will probably need most are infinite patience and persistence. Few people realize the difficulties of doing any new thing. Maybe one of the reasons people are so easily discouraged is because of their education. During all our years at school we were examined two or three times a year. If we failed once， we were out. （10）If we are going to make progress， we must learn to fail intelligently so that we won't become discouraged at the 99.9 per cent failure. 8.（）
- A、 Make sure the game is worth the candle.
- B、 That is a step in the right direction， but I don't believe it is enough.
- C、 You take the easy obstacles first and by a process of elimination you eventually arrive at the one or two major ones.
- D、 But in selecting the problem， you need to be sure to analyze it carefully to see that it is worth the effort.
- E、 Research isn't a physical thing at all； it's a state of mind.
- F、 By contrast， all research work is 99. 9 per cent failure and， if we succeed once， we are in.

第23题：
问答题Practice 12 (1) Whatever its underlying reason, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused. (2) This not only causes a litter problem, but also is a great process by persuading many of us not only to buy things we neither want nor need, but also to throw away much of what we do buy. Pollution and waste combine to a problem everyone can help to solve by cutting out necessary buying, excess consumption and careless disposal of the products we use in our daily lives.正确答案：
(1) 不管有什么内在原因,毫无疑问,只要公司、个人和政府更加努力,很多污染就可以得到控制。
(2) 这不仅导致垃圾问题,而且是一个艰巨的过程,不仅要说服我们当中的许多人买一些既不想要也不需要的东西,而且还要劝说我们扔掉买的很多东西。解析： 暂无解析 -
