被动语态 改写句子
People believe that he is ill.
改写成 It is believed that he is ill
还是It is believed that he is ill by people.
因为It不是形式宾语嘛,会不会和by people重复,导致错误呢?
或改写成He is believed to be ill
还是He is believed to be ill by people.

It is believed (by people)that he is ill .
by people一般省略
He is believed to be ill 的意思是大家期望或者大家觉得他理所当然会生病.
可以体会一下意境.
这个例子蛮好的
