资源描述

1、生活中的语法 Hi,can I use your camera on weekends?Sorry.Its being repaired.观察后的发现Now the farmers are happy and our numbers are increasing.We are being killed for the wool beneath our stomachs.Our fur is being used to make sweaters for people like you.I wonder what is being done to help you.So good things

2、are being done here to save local wildlife.我的发现1例句使用的是现在进行时,谓语动词的构成为:。2例句运用的是现在进行时的被动语态,谓语动词的构成为:。3观察以上例句可知,当把现在进行时主动语态的句子变为被动语态时,往往在be动词后加上一个来体现现在进行时,然后再把动词的现在分词形式变成来表示被动。be_(am/is/are)doingbe_(am/is/are)beingdonebeing过去分词现在进行时的被动语态一、基本用法当把现在进行时主动语态的句子变为被动语态时,往往在be动词后加上一个being来体现现在进行时,然后再把动词的现在分词形式

3、变成过去分词来表示被动,即:be(am/is/are)beingdone。点津:be动词的选择要和前面的主语保持一致。【感悟高考】(1)It is reported that many a new house _(build)at present in the disaster area.解析:由many a修饰名词,谓语动词用单数形式,由at present可知用现在进行时,由句意知为被动语态。答案:is being built(2)Hi,Torry,can I use your computer for a while this afternoon?Sorry.Its _(repair)解

4、析:由语境及“sorry”知,“我的电脑正在被修理”。答案:being repaired二、现在进行时的被动语态的用法1表示此时此刻正在进行的被动的动作。My sister is now being interviewed.我妹妹正在面试。Yao Ming is now being treated in China.姚明正在中国接受治疗。2表示现阶段正在进行的被动的动作。Preparations are being made for the 2012 Olympic Games in London.伦敦正在为2012年的奥运会做准备。Many interesting experiments a

5、re being carried out these days.这些天正在进行着许多有趣的实验。(说话时,并不一定正在进行)It is reported that the tomb in Henan is still being dug.据报道河南的那个墓仍然正在挖掘中。3表示反复进行的被动的动作。always,frequently,constantly等和现在进行时的被动语态连用表示反复进行的被动的动作,这种动词形式常用来表示赞扬或厌恶的感情色彩。What makes me angry is that the goods in my shop are always being stolen.

6、使我生气的是我店里的商品总是被偷走。I feel very surprised that the window of our classroom is frequently being broken.我感到很吃惊的是我们教室的那扇窗户经常被打破。三、使用现在进行时的被动语态要注意的问题1不可漏掉being。若漏掉,则成为一般现在时的被动语态或系表结构。Look!The children are being taken care of by their aunt.瞧!那些孩子正由他们的姑妈照看着。Children are taken good care of at school.孩子们在学校被照

7、看得很好。指通常情况The report is being written by one of the best students.报告正由一个最好的学生写着呢。The report is well written.这个报告写得很好。系表结构2可与部分情态动词连用,表示对正在发生的事情的推测。She may be being punished by her mother.她也许正被母亲惩罚着。3有时可表示按计划或安排将要进行的一个被动动作。A celebration is being held this weekend for his success.这个周末将为他的成功举办庆祝会。4某些表示

8、“状态、心理活动、存在”等的动词,如want,need,love一般不用现在进行时的被动语态,而常用一般现在时的被动语态。With the population increasing,more land is needed.随着人口的增长,需要更多的土地。Bruce Li is still loved by many young people.李小龙仍然受着很多青年人的喜爱。5“beunder/in.n.”可表示现在进行时的被动意义。The problem is under discussion at the meeting.The problem is being discussed at

9、the meeting.这个问题正在会议上讨论。This life is in use.This life is being used.这部电梯正在使用中。My computer is under repair.My computer is being repaired.我的电脑正在维修中。点津:现在进行时的被动语态的否定式是在am/is/are后加not,而不是在being后,疑问式是把am/is/are放在主语之前即可。即:否定式:主语am/is/arenotbeing及物动词的过去分词。The matter isnt being discussed now.现在没有讨论那件事情。一般疑问

10、式:Am/Is/Are主语being及物动词的过去分词Is the matter being discussed now?现在在讨论着那件事情吗?【感悟高考】(3)Would you please keep silent?The weather report _(broadcast)and I want to listen.(4)The church tower which _(restore)will be open to tourists soon.The work is almost finished.is being broadcastis being restored点津:有些被动语

11、态的考查往往和主谓一致一起考查。这时不仅要选对现在进行时的被动语态结构,同时又要考虑主谓一致的情况。被动语态有时和时态一起考查,既考查语态,又考查时态。要注意每个时态的标志词;如完成时的so far,recently,yet等,现在进行时的now,this time,现在时的sometimes等。有时要注意句子中的时间暗示。建议信的写作.题目要求假如你是李华,上周日去动物园,看到游客对动物乱扔石子甚至往一头大熊头上泼水,对此你感到非常气愤。现在请你用英语就此事给某报社编辑写封信,并提出你的建议;请求该报帮助呼吁人们保护和爱护动物。要求:词数120个左右。.审题谋篇1人称:第一人称。2时态:过去

12、时、现在时和将来时。3结构:写明写信的目的及你的感受;描写你的所见所闻;给出你的建议;请求该报帮助。.遣词造句1词汇:大笑 burst_into_laughter重要性 importance保护免受 protect_._from影响 affect忠诚地 faithfully仁慈 mercy2句型:有许多动物在动物园里被喂养。示例:There are many kinds of plants grown in the world.(过去分词短语作后置定语)仿写:There_were_many_animals_kept_in_the_zoo.任何虐待动物的人应该被罚款。示例:Anyone who

13、breaks the law should be punished.(who引导的定语从句)一些游客甚至往一头大熊头上泼水,这对它影响很坏。示例:He spoke highly of his role in the play,which made others unhappy.(which引导的非限制性定语从句)仿写:Anyone_who_treats_animals_badly_should_be_fined.仿写:Some_visitors_even_poured_water_onto_a_big_bears_head,_which_affected_it_badly.参考范文Dear E

14、ditor,Here I am writing to tell you something about my experience in the zoo last Sunday.I feel terribly sorry and ashamed of what people did to the animals.There were many animals kept in the zoo and it seemed that they were not being treated well.I saw many visitors throw stones at them without me
