語態(tài)是動詞的一種形式，它表示主語和謂語的關(guān)系。語態(tài)有兩種：主動語態(tài)和被動語態(tài)。如果主語是動作的執(zhí)行者，或者是說動作是由主語完成的，要用主動語態(tài)；如果主語是動作的承受者，或者是說動作不是由主語而是由其他人完成的，則用被動語態(tài)。

　　被動語態(tài)考點聚焦

　　(一)被動語態(tài)的概念：
　　不知道或沒必要提到動作的執(zhí)行者是誰時用被動語態(tài)。強調(diào)或突出動作的承受者常用被動語態(tài)（by短語有時可以省略）。

　　(二)被動語態(tài)的構(gòu)成方式：
　　be + 過去分詞，口語只也有用get / become + 過去分詞表示。

　　(三)被動語態(tài)的基本用法：
　　(1)使用被動語態(tài)時應注意的幾個問題。
　　①主動變化被動時雙賓語的變化?？聪铝欣?。
　　My friend gave me an interesting book on my birthday.
　　An interesting book was given to me(by my friend)on my birthday.
　　I was given an interesting book (by my friend)on my birthday.
　?、谥鲃幼儽粍訒r，賓補成主補(位置不變)；(作補語的)不定式前需加to。
　　The boss made him work all day long.
　　He was made to work all day long(by the boss)
　?、鄱陶Z動詞變被動語態(tài)時，勿要掉“尾巴”。
　　The children were taken good care of (by her).
　　Your pronunciation and spelling should be paid attention to.
　?、芮閼B(tài)動詞和be going to、be to、be sure to、used to、have to、had better等結(jié)構(gòu)變被動語態(tài)，只需將它們后面的動詞原形變?yōu)閎e +過去分詞。
　?、莓斁渥拥闹^語為say、believe、expect、think、know、write、consider、report等時，被動語態(tài)有兩種形式：(A)謂語動詞用被動語態(tài)，動詞不定式作主補。(B)用it作形式主語，真正的主語在后面用主語在后面用主語從句來表示。如：
　　People say he is a smart boy.
　　It is said that he is a smart boy.
　　He is said to be a smart boy.
　　People know paper was made in China first.
　　It is known that paper was made in China first.
　　Paper was known to be made in China first.
　　類似句型有:It is said / known / suggested / believed / hoped/ thought that …
