问题 单项选择题

最近关于电视卫星发射和运营中发生的大量事故导致相应的对承担卫星保险公司提出索赔的大幅增加,结果保险费迅速上升,使得发射和运营卫星更加昂贵。反过来,这又增加了从目前仍在运营的卫星榨取更多工作负荷的压力。 以下哪一项,如果是正确的,同以上信息综合在一起,能最好地支持电视卫星成本将继续增加这个结论( )

A.由于对卫星提供的保险风险仅由为数很少的单位承担,保险费必须非常高

B.若卫星到达轨道后无法工作,通常来说不可能很有把握地指出它无法工作的原因

C.要求安装在卫星上的工作能力越大,卫星就越经常出现故障

D.大多数卫星生产的数量很少,因此不可能实现规模经济

答案

参考答案:C

解析: 题干所要支持的结论是:电视卫星成本将继续增加。题干中暗含的两组推理关系是:(1) 事故增多一保费增加一卫星成本增加;(2) 卫星成本增加一卫星工作负荷增加。只有使这两组推理关系合理衔接在一起,形成循环发展的状态,才能说明卫星成本将持续增加。C项将“卫星工作负荷增加”和“事故增多”构成了联系,从而支持了结论。

     Basketball is a young game though it is over a hundred years old.  In the year of 1891, a certain

college was having some trouble with its boy students. The weather was bad. They had to stay indoors.

As they could not take part in their usual outdoor sports, they were unhappy, and some of them even

got into fights from time to time.  Finally, one of the teachers at the college asked Dr. Naismith to invent

a game so that the students might have something to play. It was not easy to invent a game because it had

to be played indoors, and the court was not very large.  Dr. Naismith thought for a few days and invented a kind of ball game. It was a fast, exciting game with much moving and passing of the ball. Usually two teams played the game.,  In order to make a score, the ball had to be thrown into a basket ten feet above the floor on the wall. At each end of the court there was such a basket. At first, Dr. Naismith had planned to

have the ball thrown into a box. As he could not find boxes of the right size, he had to use fruit baskets.

Dr. Naismith put two fruit baskets on the walls of both sides. There were nine plavers on each side. The

players tried to throw the ball into the baskets.  There were no holes at the bottom of the baskets.  When

a ball went into the basket, it stayed there.  The game had to stop.  A player had to climb up to get the

ball out. Later people used net baskets. Now only ten members play the game. There are five players on

each side. Basketball today is played in many countries.
