第一节(共15小题;每小题2分,满分30分)

In the United States, it is not usual to telephone someone early in the morning. If you telephone early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. So it is with the telephone calls made after 11:00 pm. If someone receives a call during sleeping hours, he may think that it’s a matter of life and death. The time chosen for the call communicates its importance.

In social life, time plays a very important part. In the USA guests tend to feel they are not highly regarded if the invitation to a dinner party reaches them 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 foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten. The meaning of time is not the same in different cultures that treat time differently; being on time is valued highly in American life, for example. If people are not on time, they may be regarded as impolite or not fully responsible. In the USA no one would think of keeping a business friend for an hour; it would be too impolite. A person who is 5 minutes late is expected to make a shout apology. If he is less than 5 minutes late, he will say a few words of explanation, though perhaps he will not complete the sentence.

56. A call at midnight would mean_________.

A. the matter is less important   B. the matter is too difficult to handle

C. the matter requires immediate attention   D. it is a matter of life and death

57. According to the passage, time plays a very important part in_______.

A. everyday life       B. private life   C. getting along with others       D. business

58. In the passage, the author suggests that invitation cards should be sent________.

A. three or four days before the party date in all cultures

B. three or four days before the party date in some cultures

C. three or four days before the party date in the USA

D. at your chosen time

单项选择题

从“横空出世”到随后的“星火燎原”再到近几年的“穷途末路”小灵通终于即将完成其历史使命。在表面上,小灵通占用了TD的频段,随着3G的启动,小灵通必然因为频段的清理而被“清退”:从深层看,其根本原因则是原固网运营商中国电信以及中国网通(现在的中国联通)都已经获得了移动牌照,在其他通信技术的竞争压力之下,小灵通唯有选择主动退出。对于中国通信业,因为小灵通既不属于“手机”,也不属于固定电话,它的退出,将意味着一个“有中国特色的通信时代”的终结;对于消费者,小灵通更是打破移动资费垄断坚冰的一把利斧,凭借绿色环保,尤其是费用低廉的双重优势,它迅速受到市场的广泛认可和消费者的普遍欢迎。到目前为止,小灵通在农村三、四级市场仍然拥有较高的占有率,2006年,小灵通用户突破9000万,逼近l亿,达到历史最高峰。此后,随着移动电话对固定电话功能替代的加强,小灵通的迅猛增速“嘎然而止。”随着移动资费的明显下降,小灵通费用低廉的优势不再明显;同时,由于电信和网通逐步停止对小灵通投资更新,其服务质量也开始下降,加上无法漫游的先天性不足,它的局限性日益突出。2008年的电信重组和3G发牌,让中国电信和原中国网通正式获得了梦寐以求的移动牌照,小灵通--这一曾经代表了中国电信发展移动业务冲动的特定通信产品也即将完成其历史使命。

下列说法符合文意的是()。

A.小灵通如果不用TD频段就不必退市

B.小灵通如果不退市用户就将继续猛增

C.小灵通即将完成中国电信发展移动业务的任务

D.小灵通如果受到3G的打压就失去资费的优势
