题目内容
Our teacher said that light______ faster than sound.
| A．travel | B．travels | C．travelled | D．is travelling |
B
解析试题分析：句意：我们老师说光比声音传播的更快。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，主语light表示抽象含义，不可数，故谓语动词用单数，选B。
考点：从句中的时态
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现在时态表示将来，即：主将从现，而不能使用将来时态。
