帶雙賓語的主動結構的句子，變為被動語態結構時，只能將其中的一個賓語變為主語，另一個賓語仍要保留。如果保留的是間接賓語，要在間接賓語之前加上介詞to或for.如：
She sent me a novel on my birthday.
I was sent a novel on my birthday.
-------She sent a novel to me on my birthday.
--------A novel was sent to me on my birthday.
We are taught English by her.----English is taught to us by her.
同樣類型的：give sb sth/buy sb sth； give sth to sb/ buy sth for sb.
當使役動詞和感官動詞（如make，let，hear，see等）用與被動語態時，不定式必須帶to
The boss made him work over twelve hours a day.
He was made to work over twelve hours a day.
短語動詞用於被動語態應作為一個整體，不能丟掉其中的介詞或副詞。如：
The meeting has been put off.
有些及物動詞和及物動詞短語(多表示“靜態”)不能用於被動語態，常見的有have， cost， last， hold， fit， agree with等。
有些不及物動詞以主動形式表示被動意義，常見的有cut， wash， write， sell等。
如： The shirt washes well.
動詞短語的被動語態
take care of照看 →be taken care of
cut down砍倒 →be cut down
laugh at嘲笑 →be laughed at
look after照料 →be looked after
必背被動語態的動詞短語 ，以下這些短語本身即是被動語態的形式，不需再加“by”。
be covered with 用……覆蓋著
be surprised at 對……感到驚奇
be known to 出名
be interested in 對……感興趣
be made of（from） 用……製造的
含有情態動詞的主動句變成被動句時，由“情態動詞＋be＋過去分詞”構成，原來帶to的情態動詞變成被動語態後“to”仍要保留。
歌訣是：情態動詞變動，情態加be加“過分”，原來帶to要保留。例如：
We can repair this watch in two days.
This watch can be repaired in two days.
You ought to take it away. It ought to be taken away.
They should do it at once. It should be done at once.
He is going to make it. It is going to be made（by him）.
We can change water into ice.
我們可以把水變成冰。
Water can be changed into ice.
水可以被變成冰。
You must not take out any books.
你不可以拿走任何一本書。
Any books mustn't be taken out by you.
