Question

【題目】—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】本題考查動(dòng)詞詞義辨析。prevent阻止, cause引起，discover發(fā)現(xiàn)。句意：―我們做些什么能夠阻止禽流感的蔓延呢？―試著不要買(mǎi)或吃那些沒(méi)有被檢驗(yàn)的雞肉。prevent sb. from doing sth.是固定搭配，意為“阻止某人做某事”，故選項(xiàng)A正確。
