注意：
① 带有助动词的句子转化为被动语态时，这些助动词或情态动词要根据新主语做相应的变化，例：
主动：We shall not use the washing machine again.
被动：The washing machine will not be used again.
（洗衣机不能再用了）
② 带有双宾语的授予动词，其被动语态有两种，当直接宾语作为主语时，间接宾语前面加上相应的介词(to/for/of/on)。例：
I gave him a book. （主动）
He was given a book by me. (被动）
A book was given to him by me.（被动）
（我给了他一本书）
