题目内容
16.The physics teacher once said that we first _____the lightning followed by thunders because light ______ faster than sound.( )A. | see; traveled | B. | saw; traveled | C. | saw; travels | D. | see; travels |
分析 物理老师说我们先看到闪电再听到雷声是因为光比声传播得快.
解答 答案:C,考查从句的时态.said后面跟着宾语从句,从句谓语动词应和said保持一致,因此使用see的过去式saw,但老师在讲述客观事实用一般现在时,因此第二空的主语是light,谓语动词用第三人称单数的形式,故选C项.
点评 考查从句的时态,应分析句子成分,结合题意对正确答案进行确定.
