有關(guān)職稱英語重點(diǎn)語法講解：被動(dòng)語態(tài)
在英語中，被動(dòng)語態(tài)用來描述主語是動(dòng)作的承受者，而非執(zhí)行者的情況。這種語態(tài)通常會(huì)帶有“be + 過去分詞”的結(jié)構(gòu)，其中“be”要根據(jù)主語和時(shí)態(tài)的不同進(jìn)行變化。下面是小編整理的職稱英語重點(diǎn)語法講解：被動(dòng)語態(tài)，希望能夠幫到你。
被動(dòng)語態(tài)考點(diǎn)聚焦
(一)被動(dòng)語態(tài)的概念： 不知道或沒必要提到動(dòng)作的執(zhí)行者是誰時(shí)用被動(dòng)語態(tài)。強(qiáng)調(diào)或突出動(dòng)作的承受者常用被動(dòng)語態(tài)(by短語有時(shí)可以省略)。
(二)被動(dòng)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(dòng)語態(tài)的基本用法： (1)使用被動(dòng)語態(tài)時(shí)應(yīng)注意的幾個(gè)問題。
①主動(dòng)變化被動(dòng)時(shí)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�(dòng)變被動(dòng)時(shí)，賓補(bǔ)成主補(bǔ)(位置不變)；(作補(bǔ)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(dòng)詞變被動(dòng)語態(tài)時(shí)，勿要掉“尾巴”。 The children were taken good care of (by her)。 Your pronunciation and spelling should be paid attention to。
④情態(tài)動(dòng)詞和be going to、be to、be sure to、used to、have to、had better等結(jié)構(gòu)變被動(dòng)語態(tài)，只需將它們后面的動(dòng)詞原形變?yōu)閎e +過去分詞。
�、莓�(dāng)句子的謂語為say、believe、expect、think、know、write、consider、report等時(shí)，被動(dòng)語態(tài)有兩種形式：(A)謂語動(dòng)詞用被動(dòng)語態(tài)，動(dòng)詞不定式作主補(bǔ)。(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 …
(2)不能用被動(dòng)語態(tài)的幾種情況。
①所有的不及物動(dòng)詞或不及物動(dòng)詞詞組不能用于被動(dòng)語態(tài)之中。
�、诒硎緺顟B(tài)的謂語動(dòng)詞，如：last、hold、benefit、contain、equal、fit、join、mean、last、look like、consist to等。

�、葙e語是反身代詞或相互代詞時(shí)謂語動(dòng)詞用主動(dòng)語態(tài)，不能用被動(dòng)語態(tài)。
⑥賓語是同源賓語，不定式、動(dòng)名詞等謂語動(dòng)詞不用被動(dòng)語態(tài)。
⑦有些動(dòng)詞以其主動(dòng)形式表示被動(dòng)意義，特別是當(dāng)主語是物時(shí)，常見的動(dòng)詞有sell、write、wash、open、lock等。
(3)主動(dòng)形式表被動(dòng)意義。
�、佼�(dāng)feel、look、smell、taste、sound等后面接形容詞時(shí)；當(dāng)cut、read、sell、wear、write等詞帶狀語修飾語時(shí)；當(dāng)動(dòng)詞表示“開始、結(jié)束、關(guān)、停、轉(zhuǎn)、啟動(dòng)”等意義時(shí)。 This kind of cloth washes easily。這種布易洗。 These novels won’t sell well。這些小說不暢銷。 My pen writes smoothly。我的鋼筆寫起來很流暢。 The door won’t lock。門鎖不上。 The fish smells good。魚聞起來香。

(5)被動(dòng)語態(tài)與系表結(jié)構(gòu)的區(qū)別 被動(dòng)語態(tài)強(qiáng)調(diào)動(dòng)作；系表結(jié)構(gòu)表主語的特點(diǎn)或狀態(tài)。如： The book was sold by a certain bookstore。(被動(dòng)語態(tài)) The book is well sold。(系表結(jié)構(gòu))
定義
在英語中，被動(dòng)語態(tài)使用得比漢語要多，要普遍，雖然大多數(shù)句子都使用主動(dòng)語態(tài)，但被動(dòng)語態(tài)在英語中也是極為重要的，許多課本及考試乃至實(shí)際應(yīng)用中都常常涉及到這個(gè)問題。一般說來，當(dāng)強(qiáng)調(diào)動(dòng)作承受者，不必說出執(zhí)行者或含糊不清的執(zhí)行者時(shí)，多用被動(dòng)語態(tài)。需要注意的是，許多地方與漢語不同。注意：那些漢語中有“被……”的短語往往又不是被動(dòng)語態(tài)，而是主系表結(jié)構(gòu)。還有些特殊現(xiàn)象，如：“known to me的意思，英語卻應(yīng)該用被動(dòng)態(tài)。還要注意，英語的被動(dòng)語態(tài)往往由“by”引出，而有用介詞“by on foot”步行（美國(guó)人有時(shí)用“by foot”），“in carriage”（乘四輪馬車）等等。還有假主動(dòng)，真被動(dòng)的十幾個(gè)常用詞的用法，以及“so heavy to carry”而不用“so heavy to be carried”等習(xí)慣用法。有關(guān)這類情況，做到心中有數(shù)對(duì)全面掌握被動(dòng)語態(tài)，準(zhǔn)確無誤地解答習(xí)題非常關(guān)鍵，被動(dòng)態(tài)必須涉及的是動(dòng)詞的各種時(shí)態(tài)變化的問題。英語的時(shí)態(tài)本來很復(fù)雜，怎樣記住各自的被動(dòng)形式呢？首先要明確“將來進(jìn)行無被動(dòng)，現(xiàn)在完成時(shí)進(jìn)行同”。這兩種時(shí)態(tài)無被動(dòng)形式。
另外，不及物動(dòng)詞帶有同源賓語的動(dòng)詞，反身代詞的動(dòng)詞和系動(dòng)詞都無被動(dòng)形式。即便如此，還有不定式，動(dòng)名詞，分詞，以及它們的復(fù)合結(jié)構(gòu)的被動(dòng)態(tài)，再加上情態(tài)動(dòng)詞，助動(dòng)詞以及它們的疑問式和否定式從中摻雜。下面口訣就以動(dòng)詞“do”為例，即“do、did”過去式“done”過去分詞，以口訣形式總結(jié)各種時(shí)態(tài)的被動(dòng)態(tài)。一定對(duì)你有所啟示。 當(dāng)然了，被動(dòng)語態(tài)也可以概括為“be done”。也就是“be+過去分詞”例如：be said。

The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
4.如果是接雙賓語的動(dòng)詞改為被動(dòng)語態(tài)時(shí)，直接賓語（物）作主語，那么動(dòng)詞后要用介詞，這個(gè)介詞是由與其搭配的動(dòng)詞決定。
He gave me a book.→A book was given to me by him.
He showed me a ticket.→A ticket was shown to me by him.
My father bought me a new bike. →A new bike was bought for me by my father.
5.一些動(dòng)詞短語用于被動(dòng)語態(tài)時(shí)，動(dòng)詞短語應(yīng)當(dāng)看作一個(gè)整體，而不能丟掉其中的介詞或副詞。
We can’t laugh at him. →He can’t be laughed at by us.
He listens to the radio every day. →The radio is listened to by him every day.
The nurse is taking care of the sickpeople. →The sickpeople is being taken care of by the nurse.
構(gòu)成
be+done.

2）被動(dòng)語態(tài)的用法
當(dāng)不知道或沒有必要指出動(dòng)作的執(zhí)行者時(shí)，常用被動(dòng)語態(tài)，這時(shí)往往不用by短語。The front window in the classroom was broken yesterday.
昨天，教室的前窗被打破了。(不知誰打破的)
They have been poorly paid.
他們的工資太低。(沒必要指出工資是誰付的)

These books are written especially for children.
這些書是專門為孩子們寫的。(強(qiáng)調(diào)的是“這些書”)
被動(dòng)語態(tài)的易錯(cuò)點(diǎn)
被動(dòng)語態(tài)的易錯(cuò)點(diǎn)主要有以下幾點(diǎn)：
在時(shí)間、條件狀語從句中，要用一般現(xiàn)在時(shí)的被動(dòng)語態(tài)表示將來時(shí)的被動(dòng)語態(tài)。例如：
If I am given enough time, I will do it better. 給我足夠的時(shí)間，我會(huì)做得更好。
固定結(jié)構(gòu)中的介詞或副詞在被動(dòng)結(jié)構(gòu)中不可省去。例如：
Such a bad habit should be got rid of. 這樣的壞習(xí)慣應(yīng)該改掉。
有些動(dòng)詞如write, read, sell，wash, open等當(dāng)強(qiáng)調(diào)動(dòng)作執(zhí)行情況時(shí), 有被動(dòng)語態(tài); 當(dāng)用作不及物動(dòng)詞來說明主語本身所具有的特征時(shí),無被動(dòng)語態(tài)。例如：
The computers were sold out, because they sell well. 電腦被賣光了，因?yàn)樗鼈冑u得好。The cloth washes easily. 這布很好洗。
在“too…to…”結(jié)構(gòu)和形容詞enough to do結(jié)構(gòu)中,通常用主動(dòng)形式表示被動(dòng)意義。例如：
The problem is too difficult to work out. 這問題太難解決了。I am not enough strong to lift the box. 我沒有足夠的力量搬起這個(gè)箱子。
