3、 go out of the classroom.I was made to go out of the classroom(by the teacher).老师让我从教室里出去。(2)动词短语,如look after,take care of等用于被动语态中时,要保留介词或副词。*Now the old couple are taken good care of by the local government.现在这对老夫妇被当地政府照顾得很好。3.被动语态常用下列情况:(1)强调动作的承受者(有时用 by 短语来强调动作的执行者)。This work must be done by you
4、,and not by me.这件工作必须由你做,而不是我来做。(2)不知道或不必说出动作的执行者。Every year a lot of people are killed in the traffic accidents.每年都有许多人死于交通事故。(3)为了表示委婉或礼貌,避免提及动作执行者或说话者自己。You are friendly invited to come to our English party at 8:00 p.m.tomorrow.敬请您明天晚上8:00参加我们的英语晚会。(4)动作的执行者是无生命的事物。The famous museum was practical

6、getables or fruit.很难说西红柿属于蔬菜还是水果。(2)有些动词用主动形式表示被动意义以说明主语的性质,如clean,sell,lock,open,write,read,wash等,此时多与副词easily/poorly/well等连用。*This kind of cloth washes easily and lasts long.这种布料很容易洗,并且耐穿。(3)表示感官的连系动词,如look,smell,taste,feel,sound等,不用被动语态,后常跟形容词作表语,表示主语的特征。*The food tastes delicious.这食物尝起来美味可口。(4)动

8、ng/to be examined by the doctor.病人需要接受医生的检查。【即学活用】语法填空。(1)(2018北京高考)Their findings _(publish)in Current Biologyin 2017.(2)The researchers _(provide)with the latest equipment now.(3)Food production will need _(raise)by 50 percent.were publishedare providedraising/to be raised二、主谓一致 在英语句子里,谓语动词必须和主语在人
9、称和数上保持一致,这就叫主谓一致。主谓一致大致可归纳为三个原则,即语法一致原则、意义一致原则和就近原则。1.语法一致原则。语法一致就是谓语动词和主语在单、复数形式上保持一致。(1)单数名词或代词、单个动词不定式短语、动名词短语或从句作主语时,谓语动词一般用单数形式。*(2019江苏高考)Yet walking upright has its disadvantage.然而,直立行走也有缺点。*Whether he has signed the contract or not doesnt matter.他是否在合同上签了字是无关紧要的。(2)由连接词and或both.and.连接的主语后面,一

13、d their composition.一半的学生已经完成了他们的作文。(3)表示金钱、时间、距离、长度、体积、面积、重量、价格等的名词或名词短语作主语时,通常把这些名词(短语)看作一个整体,谓语动词一般用单数。*Thirty years is not a long time.三十年不是很长的时间。(4)many a 或 more than one+n.作主语时,谓语动词多用单数形式。*Many a boy learns to swim before he can read.许多男孩还不会认字就学习游泳。(5)“定冠词the+形容词或分词”,表示某一类人时,谓语动词用复数;表示某一类事物时,谓

15、们和老师都想去爬山。(2)there,here引导的句子,其主语是一系列事物时,使用就近原则。*Here is a pen and some pieces of paper for you.给你一支钢笔和几张纸。【易错精点】(1)当and连接的两个名词表示同一个人,或表示一副刀叉时,谓语动词用单数形式。例如:*A writer and singer is buying a knife and fork which is worth$500.一名作家兼歌手正在买价值500美元的一副刀叉。(2)a piece of/pieces of,a pile of/piles of,a ton of/ton
