题型：不详难度：来源：
Our physics teacher told us light __________ faster than sound last term.| A．travels | B．travel | C．travelled | D．travelling |
|
答案
| A |
解析
试题分析：句意：上学期我们的物理老师告诉我们光比声音传播得快。结合语境可知宾语从句中描述的是客观性动作，故用一般现在时态。Light是抽象名词，不可数，故谓语动词用单数。选A。
点评：英语宾语从句的时态和主句没有必然的联系，需结合语境进行具体分析。而英语状语从句的时态与主句有比较紧密的联系，若主句为一般将来时，时间和条件状语从句通常要用一般现在时表示将来，而不能直接使用将来时态。 |
