被动语态表示主语是谓语动作的承受者，被动语态由“be + V-ed”构成。be随着主语人称和数以及时态的不同而变化。含有情态动词的被动语态由“can / must / may / shuld … + be + V-ed”构成。
The first sectin f New Cllege English is designed fr speaking practiceand is based n pictures and tpics.　　
These cmputers were made in ur wn cuntry last year.
Shall we be asked t attend the pening ceremny?　
①一般现在时的被动语态：am/is/are + V-ed　　
②一般过去时的被动语态：was/were+ V-ed
③一般将来时的被动语态：will/shall+be+ V-ed
They didn’t ffer Ann the jb.
Ann wasn’t ffered the jb.
(2)直接宾语做主语，需在间接宾语前加t或者fr.
The jb wasn’t ffered t Ann.
She made me a cake.
(1)间接宾语(通常指人)做主语，直接宾语依然保留在谓语后边。
A cake was made fr me.
1.有些动词可以有两个宾语，直接宾语与间接宾语。
2. 在使役动词have, make, get以及感官动词see, watch, ntice, hear, feel, bserve等后面不定式作宾语补语时，在主动结构中不定式t要省略，但变为被动结构时，要加 t。
They make her clean the flr. 
She is made t clean the flr by them.
3. It + be + V-ed + that从句 (=主语+ be + V-ed + t d sth.)表示：据说/据报道/据悉/据信等……
据说这个男孩已经通过了这次全国性的测试。
It is said that the by has passed thenatinal exam. The by is said t have passed thenatinal exam.
1. 某些感官动词加形容词及少数其他的动词与一些副词连用表示被动意义。smell, taste, prve, sell, etc.1) The dish tastes delicius. 2) The thery prved right at last.3) The bk is s interesting that it sells well.4) The pen writes well.
不可以变成被动语态的情况
need做实意动词时，need + V- ing主动形式表示被动意义。我的车需要修理。My car needs repairing. (= t be repaired).
战争爆发了。The war brke ut.但不能说：The war was brken ut.
3. 通常只有及物动词（组）才有被动语态，不及物动词没有。
“be + V-ed”这个结构并不都是被动语态，也可能是系表结构。被动语态与系表结构主要区别是：被动结构表示一个动作，而系表结构表示主语的特点或所处的状态，试比较下面的句子：
被动结构与系表结构的区别
The enemy was sn surrunded by us.The huse is surrunded by trees.She was bitten by the dg in the darkness. I was excited at the news that my husbandgt prmted.
一般现在时、一般过去时和一般将来时的主动结构和被动结构 (以动词d为例)：
情态动词具有一定的意义，但不能单独作谓语，其后需接动词原形一起构成句子的谓语。情态动词(除have t以外)没有人称和数的变化。另外，情态动词可用来构成否定句、疑问句并进行简略回答。初中常见的情态动词有：can, may, must, need, have t, culd, shuld, ught t 等。
考点一：考查表示“能力”的情态动词
1. — ________ yur Australian friend eat with chpsticks? — Yes, but she can’t use them well. A. Shuld B. Need C. Can D. Must2. — Culd yur father play glf when he was yung? — N, he ________. But he ________ play table tennis. A. culdn’t; culd B. needn’t; might C. mustn’t; shuld D. shuldn’t; need
【考点点拨】 ★情态动词can表示“能力”时，与be able t同义，其否定形式为can’t。can表示现在的能力，其过去式culd表示过去的能力。
考点二：考查表示“应该”的情态动词
1. — ________ wet finish ur hmewrk befre nn? — Yes, yu ________. A. Need; can B. Have; d C. Ought; ught t D. Shuld; must2. Yu ________ study hard if yu want t be a scientist in the future. A. may B. shuld C. wuld D. culd
【考点点拨】 ★情态动词shuld和ught t都可表示“应该”，但shuld侧重说话者主观的看法，而ught t更侧重客观情况。 ★shuld的否定形式为shuldn’t，ught t的否定形式为ughtn’t t或ught nt t。
考点三：考查表示“请求；许可”的情态动词及其回答
1. — ________ I brrw yur maths bk? — Sure. Here yu are. A. Need B. Will C. May D. Must 2. — Culd I use yur dictinary fr a while? — Yes, f curse yu ________. A. culd B. can C. will D. shuld
【考点点拨】 ★情态动词may和can都可表示“请求；许可”。may比can正式，culd在表示“请求；许可” 时，语气更委婉。 ★当“May / Can / Culd I …”表示“请求；许可”时，肯定回答常用“Yes, please.” / “Certainly.”等，否定回答常用“N, yu can’t / mustn’t.”等。
考点四：考查表示“推测”的情态动词
1. — I saw Lily in the supermarket this mrning. — Oh, it ________ her. She mved t Australia the day befre yesterday. A. can be B. must be C. can’t be D. mustn’t be2. After a lng walk, the children ________ be very tired nw. A. will B. must C. have t D. can
3. Jhn ________ g with us tmrrw, but he isn’t sure. A. must B. can C. need D. may
【考点点拨】★may, can, must都可表“推测”，三者的可能性依次递增。★may和must表“推测”常用于肯定句中，can表“推测”常用于否定句和疑问句中。
考点五：考查need, must和have t的用法
1. Jim, yu ________ play with the knife. Yu ________ hurt yurself. A. wn’t; can’t B. mustn’t; may C. shuldn’t; must D. can’t; shuldn’t 2. — ________ I have t hand in my hmewrk nw, Mr Zhang? — Yes, yu d. A. D B. Can C. May D. Must
3. — Must I get up befre six ’clck tmrrw mrning, Dad? — N, yu ________. Tmrrw is Saturday. Yu may get up a little later. A. mustn’t B. can’t C. needn’t D. may nt4. It’s t late. We ________ g hme, r we’ll be blamed (责备). A. can B. may C. might D. have t
【考点点拨】 ★need作情态动词，意为“需要”，后接动词原形，常用于否定句、疑问句和条件句中。 ★must意为“必须”，强调主观看法。对must引导的一般疑问句，肯定回答常用“must”，否定回答常用needn’t或dn’t have t。mustn’t意为“一定不要；禁止”。 ★have t意为“ 不得不；必须”，强调客观情况下需要做某事，有人称、数和时态的变化，变否定句和疑问句时需要借助助动词完成句型的变化。
