问题描述:
it is said that there have been many changes ___in my hometown in the last ten years.
A.happened B to happen C happening D happen
我看到大家多选择C.如果正确答案就是C,那么changing在这里是什么用法?
答
答案C是对的,因为前面已有动词have been
句型:THERE BE +名词+DOING STH ‘有……正在做……‘既然已经是there have been ,不可以是happened表示已经发生过了吗?不行记住:THERE BE +名词作主语(看到MANY CHANGES 了吗?),另外,HAPPEN 是不及物动词没有被动语态。
