"Intelligence" at best is an assumptive construct--the meaning of the word has never been clear. (61)There is more agreement on the kinds of behavior referred to by the term than there is on how to interpret or classify them. But it is generally agreed that a person of high intelligence is one who can grasp ideas readily, make distinctions, reason logically, and make use of verbal and mathematical symbols in solving problems. An intelligence test is a rough measure of a child’s capacity for learning, particularly for learning the kinds of things required in school. It does not measure character, social adjustment, physical endurance, manual skills, or artistic abilities. It is not supposed to-it was not designed for such purposes. (62)To criticize it for such failure is roughly comparable to criticizing a thermometer for not measuring wind velocity.The other thing we have to notice is that the assessment of the intelligence of any subject is essentially a comparative affair.(63) Now since the assessment of intelligence is a comparative matter we must be sure that the scale with which we are comparing our subjects provides a "valid" or "fair" comparison. It is here that some of the difficulties which interest us begin. Any test performed involves at least three factors: the intention to do one’s best, the knowledge required for understanding what you have to do, and the intellectual ability to do it. (64) The first two must be equal for all who are being compared, if any comparison in terms of intelligence is to be made. In school populations in our culture these assumptions can be made fair and reasonable, and the value of intelligence testing has been proved thoroughly. Its value lies, of course, in its providing a satisfactory basis for prediction. No one is in the least interested in the marks a little child gets on his test; what we are interested in is whether we can conclude from his mark on the test that the little child will do better or worse than other children of his age at tasks which we think require" general intelligence". (65)On the whole such a conclusion can be draw with a certain degree of confidence, but only if the child can be assumed to have had the same attitude towards the test as the other with whom he is being compared, and only if he was not punished by lack of relevant information which they possess. To criticize it for such failure is roughly comparable to criticizing a thermometer for not measuring wind velocity.
Tokyo is a city that you can love and hate at the same time.In Tokyo there are always too many people in the places where I want to be. Certainly there are too many cars. The Japanese drive very quickly when they can. But in Tokyo they of ten spend a long time in traffic jams. Tokyo is not different when one wants to walk.At certain times of the day there are many people on foot in London’s Oxford street. But the streets near Ginza in Tokyo always have a lot of people on foot, and sometimes it is really difficult to walk. People are very polite; there are just too many of them.The worst time to be in the street is at 11:30 at night. That is when the night-clubs are closing and everybody wants to go home. There are 35,000 night-clubs in Tokyo, and you do not often see one that is empty.Many people travel to and from work by train. Tokyo people buy six million train tickets every day. At most stations, trains arrive every two or three minutes, but at certain hours there do not seem to be enough trains. They are usually crowded, but Japanese trains are very good. They always leave and arrive on time. On a London train you would see everybody reading a newspaper. In Tokyo trains everybody in a seat seems to be asleep, whether his journey is long or short.In Tokyo, I stood outside the station for five minutes. Three fire-engines raced past on the way to one of the many fires that Tokyo has every day. Tokyo has so many surprises that none of them can really surprise me now. Instead, I am surprised at myself: I must go there next year on business. I know I hate the overcrowded city. But I feel like a man who is returning to his long-lost love.The writer think that the worst time to go into the street is when______. ______ 1Japanese trains leave and arrive______. ______ 2In Tokyo trains, every Japanese sitting in the seat______. ______ 3From the writer’s observation, we can see that fires break out______. ______ 4The writer hates Tokyo because the city is______. ______ 5 1().
