题目列表(包括答案和解析)

Life comes in a package, which includes love and hate, happiness and sorrow, failure and success, hope and despair. Life is a learning process. Experiences in life teach us new lessons and make us a better person. With each passing day we learn to handle various situations.

• Love and hate

Love plays a key role in our life. Love makes us feel wanted. In the early stage of our life, our parents shower us with unconditional love and care. They teach us about what is right and wrong, good and bad. 1. Only after we get married and have kids can we understand and become sensitive to others, feelings. On the contrary, hate can not solve any problems, but make things worse. Thus, we’d better hate less and love more.

•       Happiness and sorrow

Material happiness is short-lived, but happiness achieved by bringing a smile to others gives a certain level of fulfillment. 2.____ No mind is happy without peace. We realize the true worth of happiness when we are in sorrow. Sorrow is basically due to death of a loved one, failure or despair. But these things are temporary and will pass away anyhow.

•       Failure and success

Failure is the path to success. It helps us to touch the sky, teaches us to survive and shows us a specific way. Success brings in money, fame, pride and self-respect. 3.____ The only way to show our gratitude to God for giving success to us is by being modest, polite and respectful to the less fortunate ones.

•       Hope and despair

Hope is what keeps life going. Hope makes us dream and builds patience and confidence in us. Life teaches us not to despair even in the darkest hour because after every night there is a day. Nothing remains the same.

4.____

Life teaches us not to regret over yesterday, for it has passed and is beyond our control. Tomorrow is unknown , for it can either be bright or dull. 5.___

第四部分:任务型阅读(每小题1分,满分10分)

请认真阅读下面短文,并根据所读内容在文章后表格中的空格里填入最恰当的单词。

注意:每空格1个单词。

At the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the likelihood of death is least. Earlier we were infants and young children, and consequently more vulnerable; later, we shall undergo a progressive loss of our vigour and resistance which, though not felt at first, will finally become so sudden and quick that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us. This decline in vigour with the passing of time is called ageing. It is one of the most unpleasant discoveries which we all make that we must decline in this way, that if we escape wars, accidents and diseases we shall eventually die of old age, and that this happens at a rate which differs little from person to person, so that there are heavy odds in favour of our dying between the ages of sixty-five and eighty. Some of us will die sooner, a few will live longer-- on into a ninth or tenth decade. But the chances are against it, and there is a virtual limit on how long we can hope to remain alive, however lucky and strong we are.

Normal people tend to forget this process unless and until they are reminded of it. We are so familiar with the fact that man ages, that people have for years assumed that the process of losing vigour with time, of becoming more likely to die the older we get, was something self-evident, like the cooling of a hot kettle or the wearing-out of a pair of shoes. They have also assumed that all animals, and probably other organisms such as trees, or even the universe itself, must in the nature of things 'wear out'. Most animals we commonly observe do in fact age as we do if given the chance to live long enough; and mechanical systems like a wound watch or the sun, do in fact run out of energy in accordance with the second law of thermodynamics (whether the whole universe does so is a matter about which there may be disagreement or uncertainty at present). But these are not similar to what happens when man ages. A run-down watch is still a watch and can be rewound. An old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending. But a watch could never repair itself, it does not consist of living parts, only of metal, which wears away by friction. We could, at one time, repair ourselves well enough, at least, to overcome all but the most instantly fatal illnesses and accidents. Between twelve and eighty years we gradually lose this power; an illness which at twelve would knock us over, at eighty can knock us out, and into our grave. If we could stay as vigorous as we are at twelve, it would take about 700 years for half of us to die, and another 700 for the survivors to be reduced by half again.

 

The ____71____ of ageing

Infants and children under 12 are more easily ____72___ physically or emotionally.

At 12, we are ____73____ active and full of energy.

Later, we will ___74___ our energy or enthusiasm continuously.

Finally we can’t live any longer no matter how ___75___ we are cared for.

The characteristics of ageing

Not noticeable at first

Not avoidable in the end

Not the ____76___ speed for everyone

People’s misunderstanding of ageing

Just taking the ageing with time ____77___ for granted.

Simply thinking all living things or other systems also ___78___ the same way as we humans do.

Truth about ageing

We humans can ___79___ ourselves well enough to live a longer life, ___80___ the other living things or systems can’t.

Last year, a report by a committee of education experts said that a lot of American students cannot write well. The report noted the concerns of business leaders and teachers. The experts said that more students should have to pass a writing test before they can finish high school. They pointed out that major college entrance tests are changing now to include a writing part.

  Educators know that teaching students to write well is not easy. One problem is the amount of time needed to read through large amounts of work. So some companies have developed computer programs. These can grade student writing much more quickly than a person can. Writing tests can also cost less to carry out by computer than paper-and-pencil. These computer systems are known as e-readers. They use artificial (人工的) intelligence to think in a way like teachers. In the state of Indiana, computer grading of a statewide writing test began with a test of the system itself. For two years, both a computer and humans graded the student writing. Officials say there was almost no difference between the computer grades and those given by the human readers.

  The entrance test commonly used by business schools, the GMAT, already uses e-readers. The GRE and TOEFL tests might start; officials are deciding. The GRE is the Graduate Record Examination. TOEFL is the Test of English as a Foreign Language.

  Systems are also being used to grade writing in college classes. The computers read a few hundred examples of student writing already graded by humans. Then the systems compare new writings against those already examined.

  How do teachers feel all about this? Many say machines can never do the job as well as people can. A computer can find spelling and grammar mistakes. But these teachers say it can never really understand what a writer is trying to say. Critics say a program cannot follow a thought or judge humor or understand a beautifully expressed idea.

  But inventors of the programs say computer grading guarantees that each piece of writing is graded in the same way. They also say the systems are meant to judge knowledge more than creativity.

What do the teachers think of the computer system?

       A. They think highly of the computer systems.

       B. They think that computers cannot grade writing as well as people.

       C. They believe that computers can understand a writer’s idea well

       D. They are glad computers will spare their effort to correct students’ school work.

From the first paragraph we can conclude that _________.

       A. American students’ writing ability is being improved

       B. American students’ writing ability is not satisfactory

       C. business leaders and teachers are not worried about students’ writing

       D. all college entrance tests will include a writing part

Which of the following is NOT the advantage of e-readers?

       A. Saving much of teachers’ time.     B. Saving a lot of money.

     C. Being fair and objective.   D. Appreciating humor and beauty

The best title of this passage might be _________.

       A. Computer-graded Writing B. Human-graded Writing

       C. How to Improve Students’ Writing   D. Advantages of E-readers

When TV news programs report wars or disasters, the editors rarely use the most horrifying pictures of dead or wounded victims because they don’t want to upset their viewers. Even so, viewers are usually warned in advance that they may find some of these scenes disturbing, so they can look away if they choose. But the men and women whose job is to record those scenes-the TV cameramen-have no such choice. It is their duty to witness the horrors of the world and record them, no matter how terrible and unpleasant they may be. Consequently, it is one of the most dangerous, exposed and emotionally taxing jobs the world has to offer.

Today, the demand for their work is rising. The explosion of satellite broadcasting and 24-hour news in recent years has created an almost insatiable (贪得无厌的) demand for TV information. But major broadcasters and the TV news agencies—such as Reuters and WTN-have never had enough staff to meet the worldwide demand for up-to-date pictures, so increasingly they turn to “freelance” TV cameramen.

These freelance cameramen are independent operators tied to no particular organization. They will work for any company which hires them, be it for just a few hours or for several weeks in a war zone. But if the freelance cameraman is injured in the course of the job, the TV company is not responsible for him. The freelancer must survive on his own.

TV will always need hard, vivid moving pictures which are fresh, but these companies feel uncomfortable with large numbers of employees on their books, explains Nick Growing, once foreign editor for Britain Channel 4 News and now a BBC news presenter.

By hiring freelancers, they can buy in the skills they need only when they need them. It also enables them to contract out the risk, he says.

1.TV news agencies turn to freelance cameramen in order to           .

A.save expense and avoid risks

B.get free and useful pictures

C.get first-hand information and pictures

D.satisfy the greed of the freelance cameramen

2.We can infer from the passage that the freelance cameramen             .

A.have to take a lot of risks in the course of work

B.are tied to many TV news agencies

C.have better skills than other cameramen

D.need to contract out risks of work for TV companies

3.According to this passage, some major broadcasters and TV news agencies            .

A. have employed enough cameramen

B. are not willing to employ many cameramen

C. are very mean to freelancers

C. are responsible for the freelancer if he is injured

4.The author of this passage shows his           the freelance cameramen.

A.sympathy to       B.respect for        C.anger to          D.admiration to
