The office was cleaned yesterday. l Compare active and passive： 动作的接受者the office成了句子的主语，就应该用被动语态。从上面的例句我们可以总结：一般现在时的被动语态为：主am / is / are (not)过去分词一般过去时的被动语态为：主was / were 过去分词 如：Butter is made from milk. This house was built 100 years ago. 以前我们学过的was / were born 生于，就是一个被动语态: When were you born ? I was born in 1989.(born是bear的过去分词) 如果要特别强调动作或行为的执行者，句子后面需接by ，译为“被(由)” 如：We were woken up by a loud noise. 我们被嘈杂的声音吵醒。 (2)看图 从上面例子，我们可以看出：现在进行时被动语态的构成为：主语is / am / are + being 过去分词 再如：My car is being repaired now. Some new houses are being built near the park. 公园附近在建一些房子。 (3)请看图 BEFORE NOW从上面例子，我们可以看出现在完成时被动语态的构成为： 主语have / has been 过去分词 如：My key has been stolen. My keys have been stolen. I am not going to the party, I havent been invited. 含有情态动词的被动语态：情态动词be过去分词 A note had better be left to him. Teenagers should be allowed to wear their own clothes 这里我们列举了几个主要时态，那么其它时态呢？一般将来时 主语will be 过去分词过去将来时 主语would / should + be 过去分词过去进行时 主语was / were + being 过去分词过去完成时 主语had + been +过去分词 被动语态的时态是由be的时态决定的，be是什么时态，全句就是什么时态，be动词后面的过去分词不变。各种句式的被动语态： 肯定句：主语be + 过去分词(by) 否定句：主语be not 过去分词(by) 一般疑问句：Be 主语过去分词(by)? 特殊疑问句：疑问词be主语过去分词(by) 3. 被动语态的用法： (1)不知道或没有必要说明动作的执行者是谁，不用by动作执行者短语 Such books are written for children. 这些书是为儿童写的。I havent been told about it. 没有人告诉我这件事 (2)强调动作的承受者，这时应用by短语。 The cup was broken by David. (3)作客观说明时，常采用一种被动语态句型 Its / was said / believed / reported / + that Its reported that about three hundred people were killed in this earthquake. 据报道，这次地震中大约有三百人死亡。 4. 主动语态变为被动语态 把主动语态的句子变为被动语态的方法是： (1)把原句中的宾语变为主语 (2)动词改为被动形式，即be+过去分词 (3)原来的主语，如果需要的话，放在by后面，如果没必要，可省略。l 主动语态变成被动语态应注意事项： 从主动语态到被动语态的过程中主语、谓语动词、宾语都发生变化。 注意主格与宾格的变化形式。 注意主语的人称及数的变化对be动词带来的影响。 注意be动词的时态形式取决于原主动语态的动词时态形式。 5. 被动语态的几种类型 (1)有两个宾语的句子的被动语态(直接宾语，间接宾语)常见的接双宾语的动词有 通常这种句子可以改为以“人”当主语；和以“物”当作主语的两种被动语态。 如：He gave me a book. I was given a book by him. (以I做主语) A book was given to me by Tom. (以物book作主语) He teaches us English. We are taught English by him. (以人当主语) English is taught us by him. (以物作主语) (2)含有宾语补足语的句子的被动语态 keep, make 三类的动词常常有宾语补足语，在被动语态中，宾语补足语位置不变。 We keep food fresh in the fridge. (主 谓 宾 宾补) Food is kept fresh in the fridge. I saw him go into the office building. He was seen to go into the office building. 英语中有“十大动词”的说法:即feel , hear , listen , have , make , let , look , watch ,see , notice ，这些词在主动句中，其后的动词不定式不加to，但变被动句时必须加to. (3)含有短语的主动语态变被动语态 不及物动词没有宾语，因此没有被动语态。但有的不及物动词后面加上介词及其他一些词类构成短语动词之后，其作用相当于及物动词，可以接宾语，因而也可以变为被动语态。在变成被动语态时，不能去掉构成短语动词的介词或副词 They take good care of my child. 他们把我的孩子照顾得很好。 My child is taken good care of I turned off the radio. The radio was turned off(by me.)l 附：动词短语的被动语态: take care of be taken care of cut down be cut down laugh at be laughed at look afterbe looked after 下列这些短语本身即是被动语态的形式，不需再加by be covered with 用覆盖着 be interested in 对感兴趣 be surprised at 对感到惊奇 be made of (from)用制造的(4)由情态动词形成的被动语态 含有情态动词的句子在变为被动语态时，在情态动词后面加上be动词即可，其句型如下：肯定句：主语情态动词(can , may , must)+be+ 过去分词否定句：主语情态动词not + be + 过去分词疑问句：情态动词(Can , May , Must )主语be过去分词. 如：We should allow teenagers to surf the Internet. Teenagers should be allowed to surf the Internet. Can you use it? 你会使用它吗？ Can it be used ? 6. 不能用于被动语态的几种情况 (1)当主动结构中的宾语是反身代词和相互代词时，不能改为被动语态。 他在镜中看见了自己的模样。We often help each other. 我们常常互相帮助。 (2)当谓语是表状态的及物动词时(如have, like, take place , belong to ) I like these flowers. 我喜欢这些花。I will have a meeting.不说A meeting will be had. 应说A meeting will be held . (五) 重点、难点： 1. the other day 我们还可以说the other day , morning , week , month. 不久前的一天，一个上午、一个星期、一个月等 I saw him in London the other day. 我最近有一天在伦敦见过他。 2. get to 着手做某事 and I got to talking about the rules He got to doing the homework after supper. 3. concentrate on sth . 专注于某事(做某件事而不做其他事) He decided to concentrate on English because he just failed the exam. 他决心专攻英语因为他刚刚考试不及格。 This company concentrates on the Chinese market. 这家公司把重点集中在中国市场。 4. be good for 对有好处 有益于(that is good for studying ) This kind of food is good for me. 这种食物对我身体有益 Sunshine is good for plants. 阳光对植物有益。 5. Its a good idea for sb to do sth. 做对来说是个好主意(Its also probably a goodidea for parents to allow ) Its a good idea for us to travel to the south. 6. get noisy 变得嘈杂(I know we got noisy sometimes , ) noise noisy 7. learn from 向学习，从中学习 but we learn a lot from each other. We should learn from our mistakes. 我们应从错误中学习。 8. at present. (At present theyre too short.) at present 此刻、现在at this time , now I cant help you at present Im too busy 我现在帮不了你实在太忙了。 9. have an opportunity to do sth 有做的机会 have no opportunity to do 没机会做 I hope to have an opportunity to go to the States. I have no opportunity to have a talk with her 注意：文中在谈论将来时，用了一些动词过去式和would + 动原的形式 这是虚拟语气。表示对将来的一种假设。 (六)本单元其他句型结构： 1. sixteen-year-olds十六岁的青少年 它相当于一个名词,相当于sixteen -year- old kids. “一个16岁青少年的表达方式”a kid sixteen years old a kid of sixteen a kid of sixteen years old. a sixteen-year-old kid 2. stop doing停止做某事 He should stop wearing that silly earring.
