　　A punctual(严守时刻的) person is in the habit of doing a thing at the proper time and is never late in keeping an appointment. The unpunctual(不准时的) man never does what he has to do at the proper time. He is always in a hurry and in the end loses both time and his good name. A lost thing may be found again, but lost time can never be regained. Time is more valuable than material things. In face, time is life itself. The unpunctual man is for ever wasting and mismanaging his most valuable asset (财产) as well as other's. The unpunctual person is always complaining that he finds no time to answer letters, or return calls or keep appointments promptly. But the man who really has a great deal to do is very careful of his time and seldom complains of want of it. He knows that he can not get through his huge amount of work unless he faithfully keeps every piece of work when it has to be attended to.

　　Failure to be punctual in keeping one's appointments is sign of disrespect towards others. If a person is invited to dinner and arrives later than the appointed time, he keeps all the other guests waiting for him. Usually this will be regarded as a great disrespect to the host and all other guests present.

　　Unpunctuality, moreover, is very harmful when it comes to do one's duty, whether public or private. Imagine how it would be if those who are put in charge of important tasks failed to be at their proper place at the appointed time. A man who is known to be habitually unpunctual is never trusted by his friends or fellow men.

1．What does the author think is the main difference between a punctual person and an unpunctual person?

[　　]

A．A punctual person does everything ahead of time while an unpunctual person does everything behind schedule.

B．A punctual person does everything at the right time while an unpunctual person seldom does anything at the correct time.

C．A punctual person has a lot of appointments while an unpunctual person has few appointments.

D．A punctual person has much time to do everything while an unpunctual person has little time to do anything.

2．According to the passage, the main reason why a person is always unpunctual is that ________.

[　　]

A．he has more work to do than other people

B．he is always in a hurry when he works

C．he doesn't care much about time

D．he always mismanages and wastes his time

3．According to the third paragraph, when you are invited to dinner, you should arrive there ________.

[　　]

A．after other guests have arrived

B．before all other guests

C．at the appointed time

D．after the host has got things ready

4．Which of the following statements best describes the harm of unpunctuality?

[　　]

A．If you are an unpunctual person, you cannot be in charge of any important tasks.

B．If your friends know that you are unpunctual, they may not see you again.

C．Unpunctuality may bring about heavy losses for both public and private affairs.

D．Unpunctual may make you miss a lot of appointments and lose friends.

　　Some people believe, that international sport bring about good will between the nations and that if countries play games together they will learn to live together. Others say that international contests encourage false national pride and lead to misunderstanding and hatred. There is probably some truth in both arguments, but in recent years the Olympic Games have done little to support the view that sports encourage international brotherhood. Not only was there the terrible incident including the murder of athletes, but the Games were also ruined by small incidents caused by less important national contests.

　　One country received its second-place, medals with anger after the hockey(曲棍球) final. There had been noisy scenes at the end of the hockey match, the losers against the final decisions. They believed that one of their goals should not have been disallowed and that their opponents'(对手) victory was unfair. Their manager was very angry when he said:“This wasn't hockey. Hockey and the International Hockey Federation are finished.”The American basketball team announced that they would not give up first place to Russia, after a disputable(可争议的) end to their contest. The game had ended in disorder. It was thought at first that the United States had won, by a single point, but it was announced that there were three seconds still to play. A Russian player then threw the ball from one end of the court to the other, and another player popped it into the basket. It was the first time the USA had ever lost an Olympic basketball match. An appeal jury(评判委员会) debated the matter for four and a half hours before announcing that the result would stand. The American players then voted not to receive the silver medals.

　　Incidents of this kind will continue as long as sport is played competitively rather than for the love of the game. The suggestion that athletes should compete as individuals(个人), or in non-national teams might be too much to hope for. But in the present organisation of the Olympics there is far too much that encourages aggressive patriotism(爱国主义).

1．What did the manager mean by saying “… Hockey and the International Hockey Federation are finished?”

[　　]

A．His team would no longer take part in international games.

B．Hockey and the Federation are both ruined by the unfair decisions.

C．There should be no more hockey matches organized by the Federation.

D．The Federation should be broken up as soon as possible.

2．The basketball example implied that ________.

[　　]

A．too much patriotism was shown in the incident

B．the announcement to make the match longer was wrong

C．the appeal jury spent too much time in making the decision

D．the American team was right in refusing to accept the silver medals

3．The author gives the two examples in Paragraphs 2 and 3 to show ________.

[　　]

A．how national pride led to undesirable incidents in international games

B．that sportsmen love their country more than they used to

C．that competitiveness in the games discourages international friendship

D．that it is right for athletes to play competitively

4．What conclusion can be drawn from the passage?

[　　]

A．The organisation of the Olympic Games must be improved.

B．Athletes should compete as individuals in the Olympic Games.

C．Sport should be played competitively rather than for the love of the game.

D．International contests bring about misunderstanding between nations.
