Question

【题目】Tom was cleaning the room while Jack _______ TV.

A.watchesB.is watchingC.was watchingD.watched

Answer 1

【答案】C

【解析】

句意：汤姆在打扫房间，杰克在看电视。

考查时态。watches动词三单；is watching现在进行时；was watching过去进行时；watched过去式； while通常和延续性动词连用，用于进行时态，结合“Tom was cleaning the room while Jack _______ TV.”可知是两个同时进行的持续性动作，所以此处是“was watching”，故选C。
