自吉姆回来已经有一个月了。

如：I have kept the book for two days.

== I borrowed the book two days ago.

== It is（/ has been）two days since I borrowed the book.

【5】现在完成时和一般过去时的区别：

现在完成时强调的是过去的动作对现在的影响。标志词是：already, yet, just, ever, never, several times几次, before, so far迄今为止, for +时间段, since +时间点或从句，等。

一般过去时强调发生动作已经结束了，对现在没有影响；凡有过去的时间词的句子，都必须用一般过去时，不能用现在完成时。
