问题 单项选择题

有些昆虫在第一次繁殖幼虫之后便死去,另——些昆虫则在它们的下一代获得生存保证之后还能活几年。在后一种昆虫中,包括那些对生态系统做出有益贡献的昆虫,如蜜蜂。 从以上陈述中能得出以下哪项结论

B.大多数蜜蜂在下一代能够自行生活之后还会活得很好

C.蜜蜂通常不会在第一次繁殖以后立刻死亡

D.大多数昆虫一出生就能独立生活,不需要成年昆虫的照顾

答案

参考答案:C

解析: 推出结论题。从题干的叙述“有些昆虫在第一次繁殖幼虫之后便死去,另一些昆虫如蜜蜂则它们的下一代获得生存保证之后还能活几年”可以得出“蜜蜂通常不会在第一次繁殖以后立刻死亡”的结论。因此,C正确。B项是干扰项,其断定超出了题干的范围,题于没说它们还会活得很好,只是能推出它们还能活下去。A、D项从题干得不到。

One day an old man is selling (卖) a big elephant. A young man comes to the elephant and begins to look at it slowly. The old man goes up to him and says in his ear, “Don’t say anything about the elephant before I sell it. Then I will give you twenty dollars.”“All right,” says the young man. After the old man sells the elephant, he gives the young man twenty dollars and says, “Now, can you tell me how you found the elephant’s bad ears?”“I didn’t find the bad ears,” says the young man. “Then why are you looking at the elephant slowly?” asked the old man.
