三小时后,要用 in 3 hours 还是 after 3 hours ,after 3 hours行不行?
Have you ever been to Canada?Yes,I ___ there with my parens last year.
A.have been B.have gone C.went 请说明选哪个的理由
Do you mind (me还是my ) helping you with your homework?为什么?我觉得是my,答案怎么是me.

1.两个都不行.in 接一段时间的用法：A) = within 段时表示在这段时间内
B) 用于将来时句子里,表示这段时间后
after 后只能用点时或者名词：after 5 o'clock after the liberation
2.选A.have been to swh.是个特殊的过去时句型,表示曾到过.与went用法一样.但本句中,前面问句与答语之间的必然联系要求只能选have been.
3.都行.用my叫正统,me尚未被完全接受.有种理论把分词和动名词分为ing分词和ed分词,于是就有了所谓ing分词的名词性用法.既然当分词,就不用形容词性物主代词了.
希望选为最佳.
