A.after B.in C.for
为什么呢？

正确答案应该是since.不过有个条件:就是把ago改为before.为什么总是有人上传错题让我们选啊?!造孽!!!!!

B
因为最后是ago,如果没有ago，便可用C

好像没有正确答案

我也觉得没有正确答案。
如果把AGO去掉，可以选FOR
要不就是把HAS改HAD，中间不加东西~

句中抄错了吧。。。。没有答案。。。。

He has been away from China( )three years ago .
A.after B.in C.for
选C.for
因为“has been away”现在完成时，表示这三年来都不在中国。after是在某段时间之后的意思， in 是表示将来的时间，惟独for 可已表示一段时间。

He has been away from China( )three years ago he has been away from the school for many years .中”from”可以省去吗？为什么？ He has been preparing for his wedding. have been away 和 has/have left He has gone to the south 和 He has been to the south如何区分？ He has been----12 years old,but he has ---- no money on him. The news that he has been adimitted to Beijing … He has been preparing for his wedding是什么时态？ I have been to Tai'an. He has been there,too.组成一句___ ___ I ___ ___ he has been to Tai'an _____ he graduated from university, he has been living in Beijing
