語(yǔ)法：被動(dòng)語(yǔ)態(tài)
1．英語(yǔ)中動(dòng)詞有兩種語(yǔ)態(tài)：主動(dòng)語(yǔ)態(tài)和被動(dòng)語(yǔ)態(tài)
主動(dòng)語(yǔ)態(tài)表示主語(yǔ)是謂語(yǔ)動(dòng)詞動(dòng)作的執(zhí)行者，被動(dòng)語(yǔ)態(tài)表示主語(yǔ)是謂語(yǔ)動(dòng)詞動(dòng)作的承受者。
當(dāng)我們強(qiáng)調(diào)誰(shuí)是某個(gè)動(dòng)作的執(zhí)行者，即"誰(shuí)做了某種事情"時(shí)，用主動(dòng)語(yǔ)態(tài)。
eg: Daniel bought a new computer 丹尼爾買(mǎi)了一臺(tái)新電腦。（不是別人）
如果主語(yǔ)不是動(dòng)作的執(zhí)行者，而是動(dòng)作的承受者時(shí)，就是被動(dòng)語(yǔ)態(tài)。
eg: A new computer was bought by Daniel 一臺(tái)新電腦被丹尼爾買(mǎi)了。
被動(dòng)語(yǔ)態(tài)的謂語(yǔ)由be + 動(dòng)詞的過(guò)去分詞構(gòu)成，其中be是助動(dòng)詞，隨時(shí)態(tài)改變。
一般現(xiàn)在時(shí)的被動(dòng)語(yǔ)態(tài)由"am / is / are ＋動(dòng)詞的過(guò)去分詞"構(gòu)成。
一般過(guò)去時(shí)的被動(dòng)語(yǔ)態(tài)由"was / were ＋動(dòng)詞的過(guò)去分詞"構(gòu)成。
2．被動(dòng)語(yǔ)態(tài)的用法：
當(dāng)不知道或沒(méi)必要說(shuō)明動(dòng)作的執(zhí)行者時(shí)，用被動(dòng)語(yǔ)態(tài)。
eg: Rice is grown in South China. 華南種植水稻。（沒(méi)必要說(shuō)明是誰(shuí)種）
This bridge was built 100 years ago. 這座橋是100年前建的。（不知道誰(shuí)建的）
Passive voice with 'by'
在被動(dòng)語(yǔ)態(tài)中，如果我們也要把動(dòng)作的執(zhí)行者表達(dá)出來(lái)的話，我們就在被動(dòng)句子的后面，用 "by+動(dòng)作的執(zhí)行者（賓格）"來(lái)表示。
e.g. Jack broke the window. （主動(dòng)語(yǔ)態(tài)）
The window was broken by Jack. （被動(dòng)語(yǔ)態(tài)） 窗戶是被杰克打碎的。
Meals are cooked by her mother at home. 在家飯是她母親燒的。
The book was written by him several years ago. 這本書(shū)是他幾年前寫(xiě)的。
3．難點(diǎn)：
1）. 當(dāng)一個(gè)含有復(fù)合賓語(yǔ)（賓語(yǔ)+賓補(bǔ)）的句子變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí)， 只能把賓語(yǔ)變?yōu)楸粍?dòng)語(yǔ)態(tài)的主語(yǔ)，賓補(bǔ)還放在原來(lái)的位置。
e.g. We call him Xiao Wang.--- He is called Xiao Wang.
He cut his hair short.--- His hair was cut short.
2）. 帶雙賓語(yǔ)的動(dòng)詞變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí)， 常常把間接賓語(yǔ)變?yōu)楸粍?dòng)語(yǔ)態(tài)的主語(yǔ)；如果直接賓語(yǔ)變?yōu)楸粍?dòng)語(yǔ)態(tài)的主語(yǔ)時(shí)，間接賓語(yǔ)前要加介詞to或 for.
e.g. Someone gave the boy an apple.-- The boy was given an apple.
An apple was given to the boy.
His mother bought a present for him.--- He was bought a present.
A present was bought for him.
3）. 在let, hear, watch, see, help, have 等詞的句子中，主動(dòng)語(yǔ)態(tài)不加to, 被動(dòng)語(yǔ)態(tài)要加 to.
e.g. The boss makes us work 12 hours a day.--- We are made to work 12 hours a day.
They heard the children sing that morning.--- The children were heard to sing that morning.
�、葜苯右Z(yǔ)是祈使句，根據(jù)說(shuō)話語(yǔ)氣變成ask/tell/order warn sb. to do sth.的結(jié)構(gòu)。例：
She said to me, "Stand up."→
She asked me to stand up.
Father said to his son, "Don't play football in the street."→
Father told his son not to play football in the street.
