介词及介词短语
--How long have you been in this school?
--( )two years ago.
A.For B.About C.In D.Since
A放进去是什么呢?B就是大概两年以前（这个明显错误）；C则是how soon的回答；D是不是指两年之前?那B和D又有什么区别呢?

应选since因为ago的原因.
本来回答how long 用for来回答,但后面多了个ago ,two years是时间段,加了ago就变成了时间点,所以不能再用for,：for +时间段
about two years ago 是过去时间,与一般过去时连用,本句是现在完成时,故不对.
in two years,多了个ago,在两年后,属一般将来时,对应how soon 的提问,固本句不相配.
只有since two years ago 自从两年前,since+时间点用于现在完成时,也符合how long的提问
