There is no doubt that adults, and even highly educated adults, vary gready in the speed a

nd efficiency of their reading. Some proceed very slowly throughout; others dash along too quickly and then have to regress. Poor readers in particular may lack the ability to vary their manner of reading according to the type of reading matter and to their intentions in reading it. A good reader can move at great speed through the text of a novel or similar light reading matter. He may be able to skim a page, picking up a word or two here and there, and gain a general idea of what the text is about without really reading it. In reading more difficult material, with the intention of taking in the whole of it, he will proceed more slowly, but even then he will vary his pace, concentrating on the key words and passages , perhaps re-reading them several times and pass more quickly over the remainder. A less efficient reader tends to maintain the same speed whatever the material he reads.Consequendy, even light reading matter gives him little pleasure because he reads so slowly. But this pace may be too fast for really difficult material which requires special concentration at difficult points. A type of reading which necessitates careful attention to detail is proofreading, in which the reader, in order to detect misprints in a sample print, has to notice not so much the meaning of what he reads as the exact shape and order of letters and words in the text. This is extremely difficult for most people, since they are accustomed to overlooking such details. In fact, considerable practice is required to practice this task efficiently and it can be done only by reading very slowly, and by paying comparatively litde attention to the general meaning of the text.

The author claims that there is a difference in reading speed______.

A．among readers who have different experience

B．among all the readers

C．between the poorly educated and the highly educated

D．among the highly educated people

？？Questions 1 to 5 arc based on the following passage:Shopping for clothes is not the same

？？Questions 1 to 5 arc based on the following passage:

Shopping for clothes is not the same experience for a man as it is for a woman. A man goes shopping because he needs something, his purpose is settled and decided in advance. He knows what he wants and his objective is to find it and buy it; the price is a secondary consideration.

All men simply walk into a shop and ask the assistant for what they went. If the shop has it in stock, the salesman promptly producesit, and the business of trying it on proceeds at once. All being we1l, the deal can beand of ten is completed in less than five minutes, with hardly any chat and to everyone&39;s satisfaction.

For a man, slight problems may begin when the shop does not have what he wants, or does not have exactly what he wants. In that case the salesman, as the name implies, tries to sell the customer something else. He offers the nearest he can to the article required. No good salesman bring sout such a substitute directly, he does so with skill: “I know this jacket is not the sty]e you want, Sir! but would you like to try it for size？ It happens to be the color you mentioned.”

Few men have patience with this treatment, and the usual responseis:

“This is the right color and may be the right size, but I should be wasting my time and yours by trying it on.”

Now how does a woman go about buying clothes？In almost every respect she does so in the opposite way. Her shopping not often based on need. She has never fully made up her mind what she wants, and she is only “having a look round”. She is always open to persuasion; indeed she sets great store by what the saleswoman tells her. She will try on any number of things. Uppermost in her mind is the thought of finding something that everyone thinks suits her.

Contrary to a lot of jokes, most women have an excellent sense of value when they buy clothes. They are always on the look out for the unexpected bargain. Faced with a roomful of dresses, a woman may easily spend an hour going from one rail to another, to and fro, before selecting the dresses she wants to try on. It is a 1aborious（费时的） process, but apparently an enjoyable one.

Most dress shops provide chairs for the waiting husbands.

When a man is buying clothes, .？？

A.he buys cheap things, regardless of quality

B.he chooses things that others recommend

C.he does not mind how much he has to pay for the right things

D.he buys good quality things, so long as they are not too expensive

What does a man do when he cannot get exactly what wants？

A.He buys similar things of the color he wants.

B.He usually does not buy anything.

C.He tries on some other things, but never buys anything.

D.So long as the size is right, he buys the thing.

What does the passage tell us about women shoppers？
