in+一段时间用什么时态?

如题所述

in+一段时间用什么时态如下:

当表示"在一段时间内"时,我们通常使用现在完成进行时态(Present Perfect Continuous Tense)加上介词"in"来表达。现在完成进行时态表示动作或状态从过去某一时间开始一直延续到现在,并可能继续下去。

现在完成进行时态的构成是:have/has been+动词的现在分词形式+in+一段时间。

以下是一些例句来说明这个时态的用法:

1.I have been studying English for three years.(我已经学习英语三年了。)

2.She has been working in this company since 2010.(她从2010年开始在这家公司工作。)

3.They have been living in New York for two months.(他们已经在纽约住了两个月了。)

4.We have been waiting for the bus for over an hour.(我们已经等了一小时以上的公交车了。)

5.He has been playing the piano for the past two hours.(他已经弹了两个小时的钢琴了。)

6.The children have been playing in the park all afternoon.(孩子们整个下午都在公园里玩。)

7.She has been working on her project for weeks.(她已经连续几周在做她的项目了。)

8.They have been studying for the exam since morning.(他们从早上开始就一直在为考试学习。)
