Question

高中英语问题

Shelly _______ shy as a child, but now she is very outgoing.
A.is B. was C. has been D. had been
选哪个？我在 过去式 was 和 过去完成时 had been 之间纠结。这两个时态在句中有啥区别？

Answer 1

as a child小时候，是过去时间。
而过去完成时是"过去的过去“,所以答案选B
务必记住：
过去完成时得有过去作为支点，才会有的（支点可能是时间，也可能是过去动作或状态）
如：
I had seen the film before you saw it.（过去动作you saw it是支点）
By the end of last year, I had seen the film three times.（时间状语by the end of last year是支点）
而且，过去完成时不如一般过去时常用。

Answer 2

B

追问

能帮忙解释一下为什么不选D吗？
