2.表示动作或状态从过去某一时刻开始,一直延续到现在,而且可能还要继续下去。
e.g. I’ve been at this school for over two years.
I have been a teacher for 20years.

2. 表示过去某一时间开始并持续到现在的动作或状态:
for + 时间段(持续多久), since + 时间点 / 从句(自从...)
yet否定句、疑问句(是否发生); already肯定句、疑问句(吃惊语气)

一、现在完成时的基本结构
现在完成时由“助动词have/has + 过去分词”构成。
其基本句式结构为:
① 肯定句:主语 + have/has + 过去分词 + 其他.
I have seen this film.
② 否定句:主语 + have/has not + 过去分词 + 其他.
I have not seen this film.
③ 一般疑问句:Have/Has + 主语 + 过去分词 + 其他
肯定回答:Yes, 主语 + have/has. 否定回答:No, 主语 + haven't/hasn't.
—Have you seen the film —Yes, I have. / No, I haven't.
和主语一致
have not = haven't; has not = hasn't
have/has常可缩略为 -'ve/-'s
