1. C改成what was happening.也是错得.过去进行时用法错误
2. C改成what has happened 就对了
一般都用完成时态,强调已经发生的事情
---what -------?---he hit a car.luckily,he wasn't badly hurt.
---what -------?---he hit a car.luckily,he wasn't badly hurt.
a .did he happen b.has he happened
c.was happen d.happen to him
ab我懂,排除了,但为什么不选c?如果要选c,怎么改?一定要用完成时吗?
