Passage TwoI was only eight years old when the Second World War ended, but I can still remember something about the victory celebrations in the small town where I lived on the day when the war in Europe ended. We had not suffered much from the war there. But both at home and at school I had become accustomed to the phrases "before the war" and "when the war's over". "Before the war", apparently, things had been better, though I was too young to understand why, except that there had been no bombs then, and people had eaten things like ice -cream and bananas, which I had only heard of . When the war was over we would go back to London, but this meant little to me. I did not remember what London was like.What I remember now about VE (Victory in Europe) Day was the May evening. After dinner I said I wanted to see the bonfire (大火堆) , so when it got dark my father took me to the end of the street. The bonfire was very high, and somehow people had collected some old clothes to dress the un- mistakable figure with the moustache (胡子) they had to put on top of it. Just as we arrived, they set light to it. The flames rose and soon swallowed the "guy". Everyone was cheering and shouting, and an old woman came out of her house with two chairs and threw them on the fire to keep it going.I stood beside my father until the fire started to go down, not knowing what to say. He said nothing, either. He had fought in the First World War and may have been remembering the end of that. At last he said, "Well, that's it, son. Let's hope that this time it really will be the last one."40. Where did the author live before the Second World War?A. In London.B. In a small town.C. In Europe.D. In the countryside.

When it comes to friends, I desire those who will share my happiness, who possess wings of their own and who will fly with me. I seek friends whose qualities illuminate me and train me up for love. It is for these people that I reserve the glowing hours, too good not to share. When I was in the eighth grade, I had a friend. We were shy and "too serious" about our stud- ies when it was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school, but she would come to my house and we would sit down with pencils and paper, and one of us would say:"Let's start with a train whistle today." We would sit quietly together and write separate poems or stories that grew out of a train whistle. Then we would read them aloud. At the end of that school year, we were changing into social creatures and the stories and poems stopped. When I lived for a time in London, I had a friend, he was in despair and I was in despair. But our friendship was based on the idea in each of us that we would be sorry later if we did not explore this great city because we had felt bad at the time. We met every Sunday for five weeks and found many excellent things. We walked until our despairs disappeared and then we parted. We gave London to each other. For almost four years I have had remarkable friend whose imagination illuminates mine. We write long letters in which we often discover our strangest selves. Each of us appears, sometimes in ~ a funny way, in the other's dreams. She and I agree that, at certain times, we seem to be parts of the same mind. In my most interesting moments, I often think : "Yes, I must tell..." We have never met. It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than the lifetime services of a psychologist,who will only fill up the healing silence necessary to those darkest moments in which I would rather be my own best friend. What is the best title for the passage?A. Unforgettable Experiences B. Remarkable ImaginationC. Lifelong Friendship D. Noble Companions

共用题干Interview with Allan Gray1. I was working for a multinational company in the early 1980s,and my brother asked me if I was interested in going into partnership with him to set up a language school.I'd always wanted to work for myself,and I was a bit fed up with working for someone else,so I said yes.Primarily, I wanted the freedom to make my own decisions,I wanted room to be creative,and also I wanted to be able to get the credit and keep the profits if we were successful.I was also happy to carry the can and take the blame if things went wrong.These things are not possible if you work as an employee in a large organization.2. I had to borrow money to help start the business,but we were lucky because we also had some outside capital to put into the business.These days it can be really hard to persuade banks to lend money to people who want to start a company,so we were fortunate .It was fairly easy to set up the business,because we had a very clear idea of what we wanted to do.The problem was,all our preconceptions(预想)about what it would be like to run a business were wrong. We made lots of mistakes, and we almost went bankrupt(破产的)at the beginning. At one point, we only had two students in the school.3. Far too long!We lost money for the first four years and,as I was saying,we nearly went out of business.It took quite a long time to start making profit. The best thing we did,though,was that we hired some really good people to work for us.In fact,some of those people are still work-ing for us,24 years later.

共用题干The Need to RememberSome people say they have no memory at all:"I just can't remember a thing!"But of course we all have a memory.Our memory tells us who we are.Our memory helps us to make use in the present of what we have learnt in the past.In fact we have different types of memory.For example,our visual memory helps us recall facts and places.Some people have such a strong visual memory that they can remember exactly what they have seen,for example,pages of a book,as a complete picture.Our verbal(言语的)memory helps us remember words and figures we may have heard but not seen or written:Items of a shopping list,a chemical formula,dates,or a recipe.With our emotional(情感的)memory, we recall situations or places where we had; strong feelings,perhaps of happiness or unhappiness. We also have special memories for smell,taste, touch and sound,and for performing physical movements.We have two ways of storing any of these memories. Our short-term memory stores items for up to thirty seconds-enough to remember a telephone number while we dial.Our long-term mem-ory,on the other hand,may store items for a lifetime. Older people in fact have a much biter long-term memory than short-term .They may forget what they have done only a few hours ago,but have the clearest remembrance(记忆)of when they were very young.Psychologists tell us that we only remember a few facts about our past,and that we invent the rest. It is as though we remember only the outline of a story.We then make up the details. We of-ten do this in the way we want to remember them,usually so that we appear as the heroes of our own past , or maybe victims needing sympathy(同情). Visual memory helps us recall a place we have been to.A: RightB: WrongC: Not mentioned

问答题Practice 6  There are poor teachers, to be sure, and I’m convinced the teaching profession in this country must police itself more vigorously. I’ve thought sometimes that an incompetent teacher is worse than an incompetent surgeon, since a surgeon can cut up only one person at a time. However, it is also true that no profession is made healthy by focusing only on what’ s bad, and we must begin to see teachers as part of the solution, not the problem.  Perhaps we can learn something from Japanese here. Teachers in that country are heroes of the culture. If we do so, we may come closer to identifying the reason for the differences in school performance in our two countries.

问答题Practice 10  Think carefully about the issue presented in the following excerpt and the assignment below.  We don’t really learn anything properly until there is a problem, until we make a mistake, until something fails to go as we had hoped. When everything is working well, with no problems or failures, what incentive do we have to try something new? We are only motivated to learn when we experience difficulties.  Adapted from Alain de Botton, How Proust Can Change Your Life: Not a Novel  Assignment: Does true learning only occur when we experience difficulties? Plan and write an essay in which you develop your point of view on this issue. Support your position with reasoning and examples taken from your reading, studies, experience, or observation.
