为啥选 B
I was out of town at the time ,so I don't know exactly how it ___.A was hapening B.happened为啥选 B
这个句子可以改写成:When it happened,I was out of town.But I don't know exactly how it did(= happened).在这里,HAPPEN是瞬间动词,不必用进行时.又如,When the accident happened,John was swimming in the pool./ While John was swimming in the pool,the accident happened.明白了吗?
happen在大多数情况下是个短暂动词,发生就是发生了,不能用正在进行时。
这句话的意思是“当时我出门在外,所以我不知道它是怎么发生的.”
A表示的是过去进行时态,B表示过去时。因为句子中并没有强调当时正在进行的含义,所以用过去时就可以清楚的陈述意思了。

二,I don't know how it happen...

这道题正确的解题思路是这样的:happen 这个词是瞬间动词没错,可是它是有进行时态的;如,what was happening then. 那时(正)发生什么事?而这道题只要从语义上来判断即可;
一,I don't know how it was happening at the time. 我不知道当时如何正在发生。
二,I don't know how it happened at the time. 我不知道当时如何发生。
很显然第一句( how it was happening 如何正在发生。)是有语病的。
很多同学这道题很容易会把how看作what,若这道题是I don't know exactly WHAT it ___. 那么用was happening更符合语境,表示不知道当时正发生什么事。

应该是B吧
