题目内容
4.We were chatting about the beautiful scenery in the harbour while I caught sight of a large whale jumping out of water in the distance.while改为when.分析 我们在港口聊着美丽的风景,就在那时我看到了一头大白鲸在远处的水里跳了出来.
解答 答案:while改为when
解析:while引导的从句中谓语动词为延续性动词,且时态为进行时;本题中caught sight of"看到"为短暂性动作,且时态为过去式,不符.故应该将while替换为when,when后面所接从句中的谓语动词既可以是延续性的也可以是短暂性的,且时态也随意.另外:be(was/were)doing when sb did"某人正在做某事,就在那时…"为固定用法.
点评 本题考查句子改错,做此类题题目时一定要从语法、句意、固定搭配、时态等各个方面仔细分析句子,从而找出句子的出错点及如何修改.
