英语中关于过去完成时的用法
到了王涛。自从他去了北京我们一直还没有见过彼此。 四. 过去完成时与一般过去时的区别 虽然这两种时态都表示过去发生的动作或存在的状态,但在使用时应注意以下两点: 1. 时间状语不同,过去完成时在时间上强调“过去的过去”;而一般过去时只强调过去某一特定的时间。试比较: They had arrived at the station by ten yesterday. 到昨天十点为止,他们已经到达了车站。 They arrived at the station at ten yesterday. 他们在昨天十点的时候到达车站。 2. 在没有明确的过去时间状语作标志时,谓语动词动作发生的时间先后须依据上下文来判断,先发生的用用法过去完成时,后发生的则用一般过去时。例如: She was very happy. Her whole family were pleased with her, too. She had just won the first in the composition competition. 她很高兴。她的全家对她也很满意。她刚刚在作文比赛中得了第一。 英语中过去完成时的用法就先介绍到这里,如果还想了解更多的英文内容的话,可以来网校看看。如果您对英语学习感兴趣,想要深入学习,可以了解沪江网校精品课程,量身定制高效实用的个性化学习方案,专属督导全程伴学,扫一扫领200畅学卡。
