1、精品文档Module 1Hobbies语法剖析活用简单句的五种句子结构.句子的种类按交际功能可分为陈述句、疑问句、祈使句和感叹句。按结构可分为简单句、并列句与复合句。.简单句简单句是由一个主语（或并列主语）和一个谓语（或并列谓语）构成，其陈述句的肯定式有以下五种基本句型：【主语(S)、谓语(V)、表语(P)、宾语(O)、宾语补足语(OC）】序号结构讲解例句1该句型中的谓语为不及物动词。谓语动词的前面可加情态动词或助动词。如果多个谓语动词并列，可用and，but等并列连词将它们连接起来。谓语动词在人称和数上须与主语保持一致。The first book came out in 2003.He i

2、s running fast.2SVP此句中的动词为连系动词，连系动词常用的有be，become等，部分行为动词在某些时候也可以用作连系动词，如:get，keep，turn，grow等。有些感官动词也可以作连系动词，如:look，sound，taste，smell，feel等。Trees are green.Mrs. Smith is a doctor.They are interested in P.E.3SVO此句中的动词为及物动词。动词后接宾语时应该用及物动词，若为不及物动词则须在动词后加上合适的介词。He saw a film.Jim may visit his parents tom

3、orrow.4SVOiOd此句型中的谓语动词是及物动词，后面接两个宾语，间接宾语一般指人，直接宾语一般指物。一般是“主谓间宾直宾”，也可以是“主谓直宾介词间宾”。可接双宾语的常见动词有：ask，give，send，buy,sell,bring，pass，tell，show，teach，promiser等。I will give you a book.She bought a present for her parents.5SVOC该句型中的“宾语 +宾语补足语”又叫做“复合宾语”，其特点是宾语与其补语之间是逻辑上的主谓关系。可接复合宾语的常见动词有：ask，tell，find，help，li

4、ke，take，make，let，call，watch，see，have等。The news made everyone happy.He wants me to help him.there be 句型there be句型的结构是“there be +某人/某物+某时/某地”，含义是“在某时或某地有某人或某物”。从以上讲解中我们可以初步掌握英语句子结构的一些特点：英语的句子以谓语为中心，前面是动作的执行者，后面是动作的承受者。除了基本成分之外，状语也很重要。状语可以位于句首，也可以置于谓语之后。一般来说，置于句首的多是时间、条件和原因状语，置于谓语之后的是地点、方式、原因、目的、时间和伴随状

5、语。一般过去时和现在完成时的区别.时间上有差异一般过去时与现在没有关系，与表示过去的时间状语连用，如:ago，last year，just now，the other day等。现在完成时与现在有关系,不能与表示过去的时间状语连用。如:He has come back home.（说明现在他在家。）He came back home last year.（只能说明他去年回来过,不能说明他现在在不在家，可能后来又出去了,但至今未归。).结果上有差异现在完成时和一般过去时都表示在过去完成的动作，现在完成时强调对“现在”的影响和结果，动作到现在刚完成或还在继续。一般过去时强调动作发生在“过去”，和现

6、在没有关系。【活学活用】 单项选择1）She _the piano for six years，but she doesnt play now.A. have playedB.playedC.has played答案：B从后半句可以判断她已经不再弹钢琴了，说明前面的动作和现在已经没有关系，只是单纯地陈述过去的事情，所以用一般过去时。2）We _ the museum yesterday.A. visitedB.visitC.have visited答案：A有明显的过去时间状语yesterday，可以判断用一般过去时。3）I _ stamps since I was ten years old.

7、A. collectedB.have collectedC.am collecting答案：Bsince“自从”是现在完成时的一个标志性词语，表示动作从某时开始一直延续，所以用现在完成时。4）I _ to school yesterday because I was ill.A. wentB.havent goneC.didnt go答案：C全句为因果关系，应该是“生病没有上学”，所以否定A项；陈述昨天的事情，没提到和现在的关系，所以应用一般过去时。5）I _ in Beijing for ten years.A. livedB.have livedC.has lived答案：B句意为“我住在

8、北京已经十年了”，没有任何其他提示，表示现在仍住在北京。典题精讲经典例题在对话的空格处填上适当的单词，使对话完整、正确，每空一词。A: Mum，which TV program(节目）are you 1?B:Oh，Im watching a Beijing Opera.A: Is that2interesting than a football game?B:Yes，I think3.I prefer(更喜欢)a Beijing Opera4a football game.A:Er.but I dont like it. Shall we watch a cartoon5?B:OK.Which

9、6is your favorite TV program on?A: Its usually7on Channel 8.B:But I cant get8.A: Well，it must9on Channel 6 then. Try that.B:Here it is.The cartoon10just begun. Lets watch it together.A: Thats all right.思路解析：1.从下文问话“我正在看京剧”中可以看出，上句话中问的是“看什么”。答案:watching2.从后面的than 可以看出这是一个比较级，因为interesting是个多音节形容词。答案：

10、more3.从答语yes，可以看出是肯定的形式。答案：so4. prefer.to.“喜欢胜过”。答案：to5.提出建议“我们来看卡通片而不要看京剧和球赛”，要用一个词表达此意。答案:instead6.从末尾的介词“on”判断，最爱的电视节目在哪个频道。答案：channel7.上演或是播出,但注意主语是it，所以应用被动语态。答案:showed8. not.anything=nothing。答案:anything9.must后面要接动词原形，be on channel 6 “在6频道”。答案：be10.just暗示本句应该是现在完成时。答案:has黑色陷阱：本题有两处陷阱，一是第6题，如果注意

11、不到后面的介词on，很容易理解成“你最喜欢什么电视节目”，而本题是最喜欢的节目在哪个频道，所以要填channel而不是program。第二处是第7题，很容易让人凭直觉填be，说明卡通节目在第八频道，陷阱是前面已经有be动词is了。所以填be 不对，并且还要注意动词的被动语态的运用。绿色通道：解答此类题一定要先通读全文，对对话的主要内容有一个大概的理解，并充分利用好上下文所提供的信息，注意每一处细节，对号入座，对所填的内容要进行检验，看句子是否通顺，文章是否合情理。原创题根据表格和短文判断正（T）误（F）。Recently we have made a survey about the teen

14、all is a team-work sport.(）5.The boys dont like playing computer games.思路解析：1.F从图表中可以判断，喜欢唱歌跳舞的应该是女孩子。2.T从图表中可以判断男孩和女孩都喜欢的两项是growing vegetables和playing table tennis。3.F收集洋娃娃不是一个锻炼体能的爱好，所以不能使人变强壮。4.T从文中的例子可以看出踢足球能使人理解团队合作的重要性，所以应该是一项团队运动。5.F从图中可以直接判断此项描述不合文意。黑色陷阱：第4题考查理解能力，第5题考查反向思维能力。绿色通道：注意英文图表题，一定

15、不要落下任何一个细节，要从细节中发现东西，也可以带着问题去读表。巧学法园地come out 一词多义太阳星星升起，花儿绽放，消息传出，新书出版，均用come out。Module 2Friendship语法剖析活用宾语从句在复合句中用作宾语的从句叫做宾语从句。它是众多从句中的一员，在复合句中作主句谓语动词、介词或某些形容词的宾语。.宾语从句的引导词1.陈述句充当宾语从句时，用that引导，that无词义，在口语或非正式文体中常省略。如：My teacher said I was a good boy.老师说我是个好男孩。2.当由一般疑问句充当宾语从句时，用if或whether引导，意为“是否”

16、。如：I am not sure if you are right.我不确信你是否正确。3.如果宾语从句原来是特殊疑问句，只需用原来的疑问词引导。如：I want to know where he came from.我想知道他从哪里来。.宾语从句的语序必须是陈述语序句式连词语序例句陈述句That不变I think that we can be good friends.一般疑问句if/whether改为陈述语序I cant remember if I posted the letter.特殊疑问句特殊疑问词改为陈述语序He asked who was our English teacher.

17、宾语从句与主句的时态要相互呼应主句是现在或将来时态时，从句可用任何所需要的时态。主句是过去时态时，从句要用表示过去的相应的时态。但如果从句中有明确表示过去的时间状语，则从句应用一般过去时，不用过去完成时；如从句表达的是客观规律或真理时，用一般现在时。如：She said that the earth moves around the sun.她说地球围绕太阳转。【活学活用】 单项选择1）I hope _ it will snow this winter.A. whenB.ifC.whetherD./答案：Dhope 后面应该接that引导的宾语从句，that 在句中没有任何意义，可以省略。2)

18、I dont know _ Mr.Green will come to see us.He will help us with our English.A.whyB.whenC.howD.where答案：A从下文的答语看，上文不知道的应该是“来看我们的原因”。3)I cant remember _ I have seen him before.A.whetherB.whyC.whatD.how答案：A本句表达一种不确定的概念，用whether或if。4)Do you know _？Im going to see him.Sorry，I dont know.A.where does Mr.Li

19、liveB.where did Mr.Li liveC.where Mr.Li livesD.where Mr.Li lived答案：C宾语从句要用陈述语气，排除A、B两项。从句意判断问的是“现在住哪儿？”。5)Where do you think _ he _ the computer？Sorry，I have no idea.A.；boughtB.has；boughtC.did；buyD.does；buy答案：Ado you think是插入语，可以把它去掉，分析句意应该用应用过去时态和陈述语序。6)I cant understand _ he likes computer games s

20、o much.A.thatB.whetherC.whyD.where答案：C句意为“我不理解为什么他那么喜欢电脑游戏”。7)(2010北京中考大纲卷)Do you know _ the MP3 player last week?Sorry，I have no idea.A.how much did she pay forB.how much will she pay forC.how much she paid forD.how much she will pay for答案：C宾语从句要用陈述语序，由此排除A、B两项，由last week判断应该用过去时态。8)(2010北京中考大纲卷)I

21、dont know _ tomorrow.Can you tell me?A.when we startedB.when did we startC.when we will startD.when will we start答案：C由tomorrow判断，应该用将来时态表示。典题精讲经典例题例1In the bookshop，a reader asked the shop keeper _ Who Moved My Cheese was an interesting book.A.thatB.howC.whatD.if思路解析：注意本句中斜体部分是一本书的名字谁动了我的奶酪，本句含义是“一个

22、读者问书店管理员这本书是不是有趣”。所以答案是D项。答案：D黑色陷阱：本题的主要陷阱是书名Who Moved My Cheese， 它本身含有一个who,容易给人造成误解。绿色通道：在英语中，注意书名一般都是斜体的，且书名的首字母是大写的，注意把它看成一个独立的完整的东西。例2I was told _ Bill Gates was thirteen he began to play with computers.A.that howB.how thatC.when thatD.that when思路解析：注意后面从句的含义是“比尔盖茨十三岁的时候开始玩电脑”，应该用when表示“当时”，本句中

23、的that是宾语从句的引导词。所以选D项。答案：D黑色陷阱：本句结构复杂，主要陷阱设置在when 上，它在本句中起到引导后面的时间状语的作用。绿色通道：做此类题，要慢慢理顺思路，不要钻牛角尖，当一种含义说不通时，从另一个角度或另一个含义考虑。例3(2010江苏苏州中考)I wonder _.Zebras.A.what do they call these animalsB.how they call these animalsC.what they call these animalsD.how do they call these animals思路解析：本句含义是“我想知道他们叫这些动物什

24、么”，排除B、D两项。另外宾语从句要用陈述语序。所以选C项。答案：C黑色陷阱：本句容易译成“他们怎样称呼这些动物”而错选how，注意本句中隐含句型call sb. sth.含义是“称呼某人”。绿色通道：解答本类题首先分析句意，确定引导词，然后看好语序和时态。例4(2010北京中考)Im different from my twin sister.I love dancing，_ she is interested in reading.A.so B.orC.but D.and思路解析：本句是转折关系，选择C项。答案：C黑色陷阱：本句陷阱在于选项前后都是肯定句形式，不细读题而误选D项。绿色通道：

25、并列句主要是根据句意来判断前后两句的逻辑关系，所以一定要把题读完再作判断。例5(2010重庆中考)Work hard，_ you may catch up with your classmates soon.A.orB.butC.andD.yet思路解析：本句是“祈使句and”的句型，句意为“努力学习，你会很快赶上其他同学的”，and在句中表示承接关系，所以选C项。答案：C黑色陷阱：本题的陷阱是句型，本句型区别于“祈使句or”，这个句型的含义是“，不然的话/否则”。绿色通道：祈使句后面既可以加and，也可以加or，所以要全面分析句意，再作决定。原创题There are more and big

30、It offered $6 million for the project.由第二段第一句描述可知。3.Friendship Forestry4.In 2004，2.5 billion trees were planted in China.黑色陷阱：本题的陷阱主要是数字和一些专有名称较多，容易让人觉得文章很难。绿色通道：做这种题，可以用“地毯式”搜索的方法，同时注意答题尽量规范和完整。巧学法园地学习宾从三注意：时态语序和连词。时态主从要呼应：主句若为现在时，从句时态随句意；主句若为过去时，从句时态变过去；语序要用陈述序，切莫照搬疑问句。that连接陈述句，省与不省没关系。从句若表“是否”时，

31、if，whether 均可替。特殊问句作宾语，仍用原来疑问词。三个问题须记牢，切莫丢东忘了西。Module 3On the radio语法剖析活用动词不定式和动名词作宾语在英语中，介词宾语常用动名词，不用不定式。而动词宾语，有用动名词，有时用不定式，用动名词和不定式意义变化不大，有时意义却相差甚远。有的动词后面只能接动名词作宾语，如：enjoy，mind，miss，finish，practice，suggest，feel like等。I enjoy playing basketball with you.我喜欢和你打篮球。有的动词后面只能接不定式作宾语，如：ask，agree，decide，h
