[问答题]Look at the topic headings below, marked A, B, C, D E, and F, and match them with the paragraphs in the text below. There is one extra heading which you don’t need to use.　　Questions 1-5 are based on the following passage.　　A.Gaining attention　　B.Making sense of information 　　C.Trade secrets　　D.Academic approval 　　E.A change of focus 　　F.An ancient skill　　1 ______　　The Greek philosophers knew about it and it could still dramatically improve children’s school results today, except that no one teaches it. It is a very old technique for making your memory better. Try memorizing this series of random numbers: 3, 6, 5, 5, 2, 1, 2, 4. About as meaningful as dates in history, aren’t they? It is likely that you won’t remember them in five minutes, let alone in five hours. However, had you been at a lecture given at a school in the south of England last month, you would now be able to fix them in your head for five days, five weeks, in fact for ever.　　2______　　“I am going to give you five techniques that will enable you to remember anything you need to know at school,” promised lecturer Ian Robinson to a hundred schoolchildren. “When I’ve finished in two hours’ time, your work will be far more effective and productive. Anyone not interested, leave now.” The entire room sat still, glued to their seats.　　3______　　Robinson specializes in doing magic tricks that look totally impossible, and then he shows that they involve nothing more mysterious than good old-fashioned trickery. “I have always been interested in tricks involving memory,” he explains.　　4 ______　　What Robinson’s schoolchildren get are methods that will be familiar to anyone who has dipped into any one of a dozen books on memory. The difference is that Robinson’s approach is aimed at schoolchildren. The basic idea is to take material that is random and meaningless and give them a structure. That series of numbers at the beginning of the article fits in here. Once you think of it as the number of days in the year—365—and the number of weeks—52—and so on, it suddenly becomes permanently memorable.　　5 ______　　The reaction of schools has been uniformly enthusiastic. “The pupils benefited a lot from Ian’s talk,” says Dr Johnston, head of the school where Robinson was speaking. “Ideally we should run a regular class in memory techniques so pupils can pick it up gradually.”
