问题 单项选择题

纯种赛马是昂贵的商品。一种由遗传缺陷引起的疾病威胁着纯种赛马,使它们轻则丧失赛跑能力,重则瘫痪甚至死亡。因此,赛马饲养者认为,一旦发现有此种缺陷的赛马应停止饲养。这种看法是片面的。因为一般地说,此种疾病可以通过饮食和医疗加以控制。另外,有此种遗传缺陷的赛马往往特别美,这正是马术表演特别看重的。
以下哪项最为准确地概括了题干所要论证的结论

A.美观的外表对于赛马来说特别重要。
B.有遗传缺陷的赛马不一定丧失比赛能力。
C.不应当绝对禁止饲养有遗传缺陷的赛马。
D.一些有遗传缺陷的赛马的疾病未得到控制,是由于缺乏合理的饮食或必要的医疗。
E.遗传疾病虽然是先天的,但其病变可以通过后天的人为措施加以控制。

答案

参考答案:C

解析:这是一个驳论。先指出,“赛马饲养者认为,一旦发现有此种缺陷的赛马应停止饲养”,然后以“这种看法是片面的”来驳斥,因此,争论的主题在于“是否要饲养有缺陷的赛马”。

     Mr. Richards was quite good at shooting. He had taken part in several competitions in his small town.

He had never actually won a prize, but each time he had done well, and once he had come fourth.   

     Then he had to go to a big city on business for a month, and as he had nothing to do in the evenings there,

he joined the local rifle (步枪) club, and spent several pleasant evenings shooting there.  

    The rifle club had a very good first-class team, which used to take part in a lot of important shooting

competitions. One of these took place while Mr. Richards was with them, and of course he went to see it.

felt very nervous. He could not keep his hands from trembling (颤抖) while shooting, with the result that he

did very badly. When he took his score (积分单) to the captain, he said,"After seeing my score, I feel like

going outside and shooting myself."
