问题描述：

（）1000 English words since we ( ) to this school.A.learn,come B.have learning...
（）1000 English words since we ( ) to this school.
A.learn,come
B.have learning,came
C.have been learning,come
D.have learned,came
为什么不是C?

答

已经学完了1000个单词，不会再继续下去，所以用have learned，我们来到学校是过去的事，所以用came，所以选D

答

答案：D
解释：答案C 错在后面的come这个单词。since引导的从句通常用一般过去时，而主句用现在完成时。
祝你学习进步，更上一层楼！(*^__^*)

答

第一,没听过有have been doing 这个用法,难道是完成进行时?
第二,我们自己学不用被动语态
第三,since 引导的状语从句,since后面永远是过去时.
明白?
