问题 单项选择题

土家狗是一种仅仅在美国南部生活的无毛小型野兽。在人类定居美国南部之前,土家狗的天敌都不强大,因此土家狗在美国南部繁衍旺盛。当人类开始猎取它们之后,土家狗灭绝了。因此,肯定是人们对它们的猎取导致了其灭绝。
下面哪一项如果为真,最严重地削弱了上文中的推理( )

A.人类在美国南部定居的同时,也带来了新的可能是土家狗天敌的物种
B.在第一批人类定居美国南部以来,土家狗在美国南部的某些地区仍旧存在了约300年
C.土家狗的一些品种跑得比豹类还快
D.在美国南部人们猎取了另一种容易被天敌捕食,但从来没有灭绝的哺乳动物

答案

参考答案:A

A rich American went into a shop in London. He wanted very much to buy a nice looking watch, but the owner of the shop asked five hundred dollars for it. Suddenly a young man came into the shop, took the watch out of the owner’s hands and ran out with it. It all happened in a few seconds. When the owner ran out into the street, the young man was already lost among the people.

The American went on. At the next corner, he saw the young man with the watch in his hand. “Do you want to buy a fine watch, sir?” he asked in a low voice. “It’s only a hundred dollars.” “The young man doesn’t know I saw him stealing the watch,” he thought.
