It is difficult to imagine what life would be like without memory. The meanings of thousands of everyday perceptions, the bases【B1】the decisions we make, and the roots of our habits and skills are to be【B2】in our past experiences, which are brought into the present【B3】memory.

Memory can be defined as the capacity to keep【B4】available for later use. It includes not only "remembering" thing like arithmetic or historical facts, but also any change in the way an animal typically behaves. Memory is【B5】when a rat gives up eating grain because he has sniffed something suspicious in the grain pile. Memory is also involved when a six year old child learns to swing a baseball bat.

Memory【B6】not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory storage capacity of a computer【B7】that of a human being. The instant access memory of a large computer may hold up to 100 000 "words" ready for【B8】use. An average American teenager probably recognizes the meanings of about 100 000 words of English. However, this is but a fraction of the total【B9】of information which the teenager has stored. Consider, for example, the number of facts and places that the teenager can recognize on sight. The use of words is the basis of the advanced problem solving intelligence of human beings. A large part of a person's memory is in terms of words and【B10】of words.

【B1】

A.of

B.to

C.for

D.on

第6题
The purpose of the home was to rehabilitate patients as far as possible, so that they could face the harsh realities of life outside hospital. Most of them not only suffered from some form. of nervous disease but had other handicaps as well. For most of them, the hospital had been their refuge for some time and the idea of being rehabilitated was somewhat frightening. They doubted their own capabilities, and were nervous of the effort which would be required from them.
The home contains within a research unit which is mainly concerned with overcoming the technical problems which arise from the patient's physical disabilities. Full rehabilitation involves a need for a patient to be as independent as possible physically. It is in the research centre that all types of electronic equipment are pioneered, much of it exceedingly delicate and complex. One of the things I found astonishing as I watched what was going on in the workshop was the ease with which the patients became accustomed to the equipment. This of course has the dual effect of making them physically independent and giving them the psychological satisfaction of having mastered a difficult problem. And this extra confidence is, of course, a further step towards rehabilitation.
While I was there, I was fortunate enough to be able to talk to a couple of patients who had been fully rehabilitated and who had come back for the weekend to visit their friends. One, a former physical education teacher who suffered from paralysis from the waist down, was now teaching general studies in a primary school. After his accident, he told me, he had had a complete nervous breakdown and had indeed tried to commit suicide several times. "But when I got here, I realized that there were still some things I could do, and that there were people worse off than me who were out in the world doing them," he said," Yes, I expect I shall get depressions again. You can't completely cure that kind of thing. But they'll pull me out of it, at least I know that now."
The "home" in this text refers to ______.
A.the hospital
B.the refuge camp
C.the research centre
D.the place away from reality

My wife and I spent two weeks in London last year. We went there in autumn. We think it is the best season to visit England. The weather is usually quite pleasant and there aren't too many tourists in October.
We stayed in a small hotel in the West End. It was convenient as we did most of our sight seeing on foot. Taxis were too expensive; the bus routes were too difficult for us to understand; and my wife didn't like traveling by underground. She said it made her feel shut in.
We went to look at the places, which all tourists see. We saw Buckingham Palace, the National Gallery and Piccadilly Circus. We went shopping in Oxford Street and spent too much money. What we liked most, though, was going to the theatre. We don't have the chance to see such wonderful plays at home. A lot of people say English food is very bad. We didn't think so. It's true that most of the restaurants are French or Italian or Chinese, but we had some very good meals.
In fact, we enjoyed our holiday so much that we have booked another trip to England for this year. We're going to take our umbrellas, though. I'm sure we'll need them.

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!
