题目内容
4.Henry Adamswas walking (walk) through the street when he caught sight of a tailor's shop.分析 Henry Adams正沿着这条街走这时他看见了一家裁缝店.
解答 答案是was walking.本题考查过去进行时;过去进行时表示过去某一点时间或某一段时间内正在继续的动作;本题中与"when"连用,构成句型"was/were doing…when",表示"正在做…这时";故答案是was walking.
点评 本题是要求用所给动词的适当形式填空,解题时首先考虑句中需要的是谓语动词还是非谓语动词;其次,如果是谓语动词关注时态、语态和数的变化;如果是非谓语动词要联系非谓语的基本用法判断非谓语的形式.
