★★★Grammar 被动语态
被动语态：谓语部分的结构是 be +vt.p.p （过去分词）
被动语态的句子有时态的变化， ( http: / / www.21cnjy.com )这个变化反映在be动词上。也就是说，把一个句子做成被动语态的句子，只需要写出BE动词的所需时态，再加上所给动词的过去分词就行了。
注意：be动词作为一个独立的谓语动词有自己现在分词（being）和过去分词 （been）。
一般现在时 am / is / are +vt.p.p A tree is planted every day in the park.
一般过去时 was / were+vt.p ( http: / / www.21cnjy.com ).p A tree was planted yesterday.
一般将来时 shall / will\ ( http: / / www.21cnjy.com )be going to + be +vt.p.p More trees will be planted next year.
　　过去将来时 would / should + be+vt.p.p He said more trees would be planted.
　　现在进行时 am / is / are + being+vt.p.p Some trees are being planted.
过去进行时 was / were ( http: / / www.21cnjy.com )+ being+vt.p.p Some trees were being planted at this time yesterday
现在完成时 have / has ( http: / / www.21cnjy.com ) + been+vt.p.p More tree have been planted.
　　过去完成时 had + been+vt.p.p More trees had been planted by the end of last year.
二、 有些主动结构表被动
1.write /sell 等词的一些 ( http: / / www.21cnjy.com )用法。Eg This kind of pen writes very smoothly. This kind of shirt sells well here.
2.need /want/ req ( http: / / www.21cnjy.com )uire / be worth + doing 相当于 need / want/require / be worth + be done
My bike needs repairing= My bike needs to be required.
三、无被动语态现象： belong to happen take place 等词无被动语态。
That pen belongs to Tom. The accident happened last nigh.
四、make sb do sth /see sb do sth / hear sb do sth 等词组变为被动语态后需改为 to do
Eg: I heard sing ( http: / / www.21cnjy.com )a song yesterday. Tom was heard to sing a song yesterday
They made t ( http: / / www.21cnjy.com )he workers work 10 hours every day. The workers were made to work 10 hours every day

II. 注意事项:
1：只有及物动词（vt.）才能构成被动语态( ( http: / / www.21cnjy.com )不及物动词没有被动语态)：We often plant trees in spring. →Trees are often planted in spring(by us).
2：动词短语构成被动语态时应把 ( http: / / www.21cnjy.com )短语作为整体,不能将介词或副词丢掉.she can take care of her sister→ Her sister can be taken care of (by her).
3：带有省去不定式符号“to”的主动变为 ( http: / / www.21cnjy.com )被动时“to”须加上：They made me clean the classroom→I was made to clean the clssroom (by them).
4：带复合宾语（双宾语）的主动语 ( http: / / www.21cnjy.com )态变为被动语态时，两个宾语都可作被动语态的主语，一般来说，用间接宾语，如直接宾语作主语时，间接宾语前面必须加上“to” 或for：My father gave me a present yesterday.
①间宾 ②直宾 (常用的词有give , buy , pass, show, bring等)
→I was given ( http: / / www.21cnjy.com ) a present (by my father) yesterday. A present was given to me (by my father) yesterday.
5：将被动语态变为主动语态时必须找准动作的执行者（因为在被动语态中动作和执行者往往被省略）
例：Tea is grown in the south. →Farmers grow tea in the south.
非谓语动词的被动语态:
to do---to be do ( http: / / www.21cnjy.com )ne: A wild animal zoo is to be built in our city． v.+ing ----v+ being done: I don't like being laughed at in the public.
记住：宾变主,主变宾,by短语后面跟。谓语动词变被动,be后“过分”来使用。
