he didn't see me in the street yesterday.改被动式.并说说为什么这样改

I wasn't seen in the street yesterday by him.by him和in the street yesterday 可调换位置.
原句中He作主语,因此在被动句中作宾语,改为 him （被动句：将原句中的主语改成宾语,原句中的宾语改成主语）,me 在原句中作宾语,因此改成I,放在句首作主语.至于by him和in the street yesterday 两个短语都作状语,因此无需改动,位置也可互换,哪个在前,哪个在后都无所谓.（状语你可能现在还不懂,一般高二下学期你们老师会作详细地讲解）

I were not seen by him in the street yesterday
我没有被他看见啊

i was not seen by him in the street yesterday.
宾语改为主语。

I DIDN'T TO BE MET WITH HE,YESTERDAY.被动就是把我当成被动来看，就是I DIDN'T TO BE MET，然后后面跟WITH HE，就是被动了！
