在现在完成时态 since 引导的句子中,主句的谓语动词必须用持续动词吗?
He has left here since two years ago.
He has been away since two years ago.是两个都对,还是有错?
在现在完成时态 since 引导的句子中,主句的谓语动词必须用持续动词吗?
He has left here since two years ago.
He has been away since two years ago.是两个都对,还是有错?
都不对,因为有了ago 就不能用since
ago 表示用过去时,since 是现在完成时标志
修改后如下 :
He has left here since XXXX(年份)
He has been away for 2 years.
