Task 1Directions: After reading the following passage, you will find 5 questions or unfinished statements, numbered 36 through 40. For each question or statement there are 4 choices marked A, B, C, and D. You should make the correct choice.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 clear and decided in advance. He knows what he wants, and his objective is to find it and buy it; the price is in the second place for consideration(考虑). All men simply walk into a shop and ask the assistant for what they want. If the shop has it, the salesman quickly produces it, and the man begins to try it at once. For a man, small 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 will try to sell the customer something else. Very often, he offers the nearest thing which he can produce. Now how does a woman go about buying clothes? In almost every respect, she does so in the opposite way. Her shopping is not often based on need. She has never fully made up her mind of what she wants, and she is only 'having a look round'. She will still be satisfied even if she has bought nothing.How does a man go shopping when he wants to buy something?A．He will often ask help from the shop assistant.B．He will look at it carefully and wait for a while.C．He has made a plan before he wants to buy it.D．He will discuss it with his wife and then buy it.
