第3题

Most people would agree that, although our age exceeds all previous ages in knowledge, the
re has been no corresponding increase in wisdom. But agreement ceases as soon as we attempt to define "wisdom" and consider means of promoting it. There are several factors that contribute to wisdom. Of these I should put first a sense of proportion: the capacity to take account of all the important factors in a problem and to attach to each its due weight.

This has become more difficult than it used to be owing to the extent and complexity of the special knowledge required of various kinds of technicians. Suppose, for example, that you are engaged in research in scientific medicine. The work is difficult and is likely to absorb the whole of your mind. You have no time to consider the effect which your discoveries or inventions may have outside the field of medicine. You succeed (let us say) as

modern medicine has succeeded, in enormously lowering the infant death-rate, not only in Europe and America, but also in Asia and Africa. This has the entirely unintended result of making the food supply inadequate and lowing the standard of life in the parts of the world that have the greatest populations. To take an even more dramatic example, which is in everybody's mind at the present time, you study the makeup of the atom from a disinterested (无利害关系的) desire for knowledge, and by chance place in the hands of a powerful mad man the means of destroying the human race.

Therefore, with every increase of knowledge and skill, wisdom becomes more necessary, for every such increase augments (增强) our capacity for realizing our purposes, and therefore augments our capacity for evil, if our purposes are unwise.

Disagreement arises when people try to decide ______ .

A.how much more wisdom we have now than before

B.what wisdom is and how to develop it

C.if there is a great increase of wisdom in our age

D.whether wisdom can be developed or not

I once knew a dog named Newton who had a unique sense of humour. Whenever I tossed out a Frisbee for him to chase, he’d take off in hot pursuit but then seem to lose track of it. Moving back and forth only a yard of two from the toy, Newton would look all around, even up into the trees. He seemed genuinely puzzled. Finally,I’d give up and head into the field to help him out. But no sooner would I get within 10 ft. Of him than he would run invariably straight over to the Frisbee,grab it and start running like mad, looking over his shoulder with what looked suspiciously like a grin.Just about every pet owner has a story like this and is eager to share it with anyone who will listen. On very short notice, TIME reporters cam up with 25 stories about what each is convinced is the smartest pet in the world. Among them: the cat who closes the door behind him when he goes into the bathroom; the cat who uses a toilet instead of a litter box... and flushes it afterward; the dog who goes wild when he sees his owner putting on blue jeans instead of a dress because jeans mean it is time to play; and the cat who used to wait patiently at the bus stop everyday for a little girl, then walk her the six blocks home. And so on.

These behaviors are certainly clever, but what do they mean? Was Newton really deceiving? Can a cat really desire privacy in the toilet? In short, do household pets really have a mental and emotional life? Their owners think so, but until recently, animal-behaviour exports would have gone mad on hearing such a question.

The worst sin in the worst sin in their moral vocabulary was anthropomorphism,projecting human traits onto animals. A dog or a cat might behave as if it were angry, lonely, sad, happy or confused, but that was only in the eye of the viewer.

What was going on, they insisted was that the dog or cat had been conditioned, through a perhaps unintentional series of punishments and rewards, the behave certain way.

The behaviour was a mechanical result of the training.

1. What did Newton seem puzzled about?

2. Why does the author say Newton had unique sense of humour?

3. What made it possible for the TIME reporters to come up with so many interesting stories about pets?

4.What belief about pet behaviour was unacceptable to experts of animal behaviour?

5. What is the explanation of animal-behaviour experts for the “clever” behaviour of pets?

One of the things I am really fond of is the weekly shopping experience. I like toimag

One of the things I am really fond of is the weekly shopping experience. I like to

imagine pushing the trolley slowly around the supermarket and taking anything that

interests me. But my experience is not always so exciting. First it is difficult to get

a shopping trolley. Carefully designed not only to hold all shapes and sizes of

purchases, a single trolley is hard to get out of the line of trolley s where it is

parked. Often one needs the help of two strong men. The next lesson is that women never

follow a logical route when shopping. Your wife has disappeared before you know it.

After ten minutes of searching, when you finally find her in a far corner, she

enquires: “Where have you been all this time, dear?” Supermarket managers are sent on

courses to learn how to tempt the customers and persuade them to buy goods they do not

really need, at prices they are not able afford. As a newcomer, I am often taken in by

their clever techniques, as I take many goods off the shelves. But I am often

discouraged by my wife. “Put it back, dear.” “You’ve tried that before and didn’t

take to it.” “No, it’s too expensive.” After the week’s groceries have been

collected, the last trial is passing through the checkout counter. Never join the

shortest queue. It usually contains several shoppers who pay by writing out a personal

cheque and who wait until all their purchases have been totaled up before beginning a

mad search through their handbags for their cheque books. When the book is found, the

customer never knows the date, asks again for the forgotten total and forgets to put

the address on the back. Don’t be fooled, either, by thinking that this is the end of

the exercise. When the cheque has been carefully examined by the cashier, a bell rings

, and there is a further wait until a supervisor arrives to say that the cheque can be

accepted. Then it is our turn, and the checkout girl is so quick and efficient that we

don’t have time to get our own chequebook ready. But the people who are packing our

shopping are kind and give us friendly smiles When we come once more into the great

outside world, a broken egg is running down my trousers. I hear the voice of my wife

call out: “Oops, dear, mind the trolley.” Shopping!

1. How often does the author go shopping?

A. every day

B. every week

C. every month

D. every year

2. The author does not find his shopping experience always ______.

A. exciting

B. useful

C. embarrassing

A. collecting groceries

B. passing through the checkout counter

C. having a rest

D. saying goodbye

4. Who comes to check whether the cheque can be accepted.

A. The supervisor

B. The manager

C. The salesgirl

D. The husband

5. When they come into the great outside world, the author finds that ______.

A. he can’t find the car

B. he can’t find his wife

C. a ten-dollar note on the ground

D. a broken egg is running down his trousers

第9题

Florence Stephen is 77 and lives in Deganwy, North Wales. She is reading for arts degree.
"I'm more of a creature to polish my mind than polish my furniture. The house takes second place while I put the studying first".

"I was very happy at school and had wonderful teaching. I passed the university entrance examination and was ready to go to university but with WWI I went into banking. I was paid 1 pound a week. Manchester University kept my place open for three years but I was enjoying the money and freedom. So I turned it down."

Mrs. Stephen is now in the second year of her Open University course and is finding it hard work. She underestimates her ability. "I'm feeling tired more frequently..I can't do more than an hour' s work at a time. The memory' s shocking. I' m supposed to be revising and I look up notes ! did earlier this year and think, ' Have you mad this before?' so I' m doing it very slowly—one credit a year, so it' 11 take six years."

"At the moment the greatest reward is simply the increase in knowledge'--and the discipline. I had an essay failed this week. The professor said I hadn't answered the question. I've been thinking about all week. I know I haven' t got the facility for essay construction. I just let myself to get excited. I feel more emotionally than I do mentally. I'm very ordinary really."

While claiming to be ordinary and lazy, Mrs. Stephen is still working hard daily at her assignments. Mrs. Stephen sees her studies as keeping her fit and independent. "Because of my life I' ve been self-sufficient. It' s not a very nice characteristic. It means I don' t care enough about people. I cannot say I find comfort in what I'm learning, so I'U be interested to see if there's a life ahead."

When Florence said "I' m more of a creature to polish my mind than polish my furniture", she meant that______.

A.she was tired of learning

B.she was thirsty for knowledge

C.she was more suitable for doing housework

D.she did not have enough time to keep the house clean

What kind of human being will the future spaceman be?Will he need bones of steel and pow
What kind of human being will the future spaceman be?

Will he need bones of steel and powerful muscles to resist rocket thrust,the lungs of a glass blower,a mighty heart,the calmness of an acrobat,unconscious death urges,or a schizophrenic(患精神分裂症的)drove toward isolation? Popular ideas of a spaceman tend to be funny composites of fiction and fact.

A more realistic portrait emerges from the young science of bioastronautics,the newest and strangest of medical disciplines.The astronaut may be described as a young man of high intelligence who is normal to an abnormal degree.On earth he may well have been a high diver,high jumper,pole vaulter,or acrobat.He must be highly motivated,carefully trained,and he must want to come back.

His heart and lungs must be healthy but need not be exceptionally developed,for his cabin will be pressurized.Huge muscles may actually be disadvantageous,for he will have almost no way to get exercise,and he will find that the strength of a year old child is adequate in the weightlessness of space.A firm body and a short, strong neck will help him to withstand(抗拒;经得起……)the tremendous forces encountered at take off.Most important physically,his digestive system must be one that will not be upset by weightlessness;he must not be subject to motion sickness.

() 41.All the following are popular beliefs about the future spaceman EXCEPT that .
