[阅读理解]In the United States, it is not customary(习惯上) to telephone someone very early in the morning. If you telephone him early in the day, while he is shaving(刮脸; 修面) or having breakfast, the time of the call shows that the matter(事情) is very important and requires immediate attention(注意). The same meaning is attached to telephone calls made after 11:00 pm. If someone receives a call during sleeping hours, he assumes(猜想) it's a matter of life or death. The time chosen for the call communicates(通讯) its importance.In social life, time plays a very important part. In the U.S.A. guests tend(倾向) to feel they are not highly regarded(尊重; 尊敬) if the invitation to a dinner party is extended(延长) only three or four days before the party date. But it is not true in all countries. In other areas of the world, it may be considered(受尊敬的) foolish(愚蠢的) to make an appointment(约会) too far in advance(预先, 事先) because plans which are made for a date more than a week away tend to be forgotten. The meaning of time differs in different parts of the world. Thus( 因此), misunderstandings(误解, 误会) arise(发生) between people from different cultures that treat(对待, 看待) time differently. Promptness(敏捷) is valued highly in American life, for example. If people are not prompt(准时到达的), they may be regarded(留心的,关心的,表示敬意的) as impolite(不礼貌的;失礼的;粗鲁的) or not fully responsible(负有责任的, 需承担责任的). In the U.S. no one would think of keeping a business associate(联合; 结交, 结伙) waiting for an hour, it would be too impolite. A person, who is 5 minutes late, will say a few words of explanation(解释, 说明), though perhaps he will not complete the sentence(谈判). (1)、What is the main idea of this passage? ________ A:It is not customary to telephone someone in the morning and in sleeping hours in the U.S. B:The role of time in social life over the world. C:If people are late, they may be regarded as impolite or not fully responsible in the U.S. D:Not every country treats the concept of time as the same. (2)、What does it mean in the passage if you call someone during his or her sleeping hours? _______ A:A matter of work. B:A matter of life or death. C:You want to see him or her. D:You want to make an appointment with him or her. (3)、Which of the following time is proper(适合的) if you want to make an appointment with your friend in the U.S. A.?
