He felt as if he alone were responsible for what had happene
1个回答

1.he alone were responsible for what had happened 是虚拟语气

2.非虚拟语气的正常的表达是

he is responsible for what had happened,

他以为好像只有他一个人对发生的事情负责一样(实际上不是),他以为的,不是将来,也不是过去,是一般现在式.

3.在虚拟语气里面,一般现在时,用过去式表示,并且单数人称和复数人称都用were

4.what had happened 这里之所以用过去完成时,因为这里的时间,是针对felt的时间,过去的过去,就用过去完成式.
