專(zhuān)門(mén)替中國(guó)人寫(xiě)的英語(yǔ)語(yǔ)法8-2：沒(méi)有助動(dòng)詞的被動(dòng)語(yǔ)氣

　　8-2 沒(méi)有助動(dòng)詞的被動(dòng)語(yǔ)氣

　　在這以前，我們的句子都是主動(dòng)語(yǔ)氣，這種句子的基本形式如下：

　　主詞+動(dòng)詞+受詞

　　所謂的被動(dòng)語(yǔ)氣，乃是將原來(lái)的受詞變成主詞。舉例來(lái)說(shuō)，主動(dòng)語(yǔ)氣中，我們說(shuō)〝我看到一些狗〞，在被動(dòng)語(yǔ)氣中，我們說(shuō)〝一些狗被我看到〞。在英文中，將主動(dòng)語(yǔ)氣改成被動(dòng)語(yǔ)氣，必須做以下的動(dòng)作：

　　(1)原有受詞變成名詞

　　(2)動(dòng)詞變成verb to be+過(guò)去分詞(past participle)

　　(3)原有主詞變成在動(dòng)詞后面，但前面加by。

　　舉例來(lái)說(shuō)，主動(dòng)語(yǔ)氣的句子可以是I saw a cat.被動(dòng)語(yǔ)氣就成了A cat was seen by me. 最重要的是，verb to be的時(shí)式必須和原句子的相同，以上的例子中，動(dòng)詞是過(guò)去式，所以verb to be也是過(guò)去式。除此以外，verb to be也要配合新的主詞。請(qǐng)看以下的例子：

　　I saw two cats. 改成被動(dòng)語(yǔ)氣以后，句子是Two cats were seen by me.

　　以下是主動(dòng)改被動(dòng)的例子，最重要的是注意verb to be的形式：

　　主動(dòng)語(yǔ)氣(active voice)

　　Mr. Jones hit the dog.

　　My brother saw you yesterday.

　　He sent the book to me.

　　Dickens wrote those two novels.

　　They ate all of the apples.

　　Jane wrote that song.

　　My mother loves me.

　　被動(dòng)語(yǔ)氣(passive voice)

　　The dog was hit by Mr. Jones.

　　You were seen by my brother yesterday.

　　The book was sent to me by him.

　　Those two novels were written by Dickens.

　　All of the apples were eaten by them.

　　That song was written by Jane.

　　I am loved by my mother.
