Question

【题目】—What can we do to________ bird flu from spreading?

—Try not to buy or eat chickens that have not been checked.

A. prevent B. cause C. discover

Answer 1

【答案】A

【解析】本题考查动词词义辨析。prevent阻止, cause引起，discover发现。句意：―我们做些什么能够阻止禽流感的蔓延呢？―试着不要买或吃那些没有被检验的鸡肉。prevent sb. from doing sth.是固定搭配，意为“阻止某人做某事”，故选项A正确。
