外研版八年級下冊英語知識語法匯總（經(jīng)典實用）

1、Module 1Hobbies語法剖析活用簡單句的五種句子結(jié)構(gòu).句子的種類按交際功能可分為陳述句、疑問句、祈使句和感嘆句。按結(jié)構(gòu)可分為簡單句、并列句與復(fù)合句。.簡單句簡單句是由一個主語（或并列主語）和一個謂語（或并列謂語）構(gòu)成，其陳述句的肯定式有以下五種基本句型：【主語(S)、謂語(V)、表語(P)、賓語(O)、賓語補足語(OC）】序號結(jié)構(gòu)講解例句1該句型中的謂語為不及物動詞。謂語動詞的前面可加情態(tài)動詞或助動詞。如果多個謂語動詞并列，可用and，but等并列連詞將它們連接起來。謂語動詞在人稱和數(shù)上須與主語保持一致。The first book came out in 2003.He is ru

2、nning fast.2SVP此句中的動詞為連系動詞，連系動詞常用的有be，become等，部分行為動詞在某些時候也可以用作連系動詞，如:get，keep，turn，grow等。有些感官動詞也可以作連系動詞，如:look，sound，taste，smell，feel等。Trees are green.Mrs. Smith is a doctor.They are interested in P.E.3SVO此句中的動詞為及物動詞。動詞后接賓語時應(yīng)該用及物動詞，若為不及物動詞則須在動詞后加上合適的介詞。He saw a film.Jim may visit his parents tomorro

3、w.4SVOiOd此句型中的謂語動詞是及物動詞，后面接兩個賓語，間接賓語一般指人，直接賓語一般指物。一般是“主謂間賓直賓”，也可以是“主謂直賓介詞間賓”?？山与p賓語的常見動詞有：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該句型中的“賓語 +賓語補足語”又叫做“復(fù)合賓語”，其特點是賓語與其補語之間是邏輯上的主謂關(guān)系。可接復(fù)合賓語的常見動詞有：ask，tell，find，help，like，t

4、ake，make，let，call，watch，see，have等。The news made everyone happy.He wants me to help him.there be 句型there be句型的結(jié)構(gòu)是“there be +某人/某物+某時/某地”，含義是“在某時或某地有某人或某物”。從以上講解中我們可以初步掌握英語句子結(jié)構(gòu)的一些特點：英語的句子以謂語為中心，前面是動作的執(zhí)行者，后面是動作的承受者。除了基本成分之外，狀語也很重要。狀語可以位于句首，也可以置于謂語之后。一般來說，置于句首的多是時間、條件和原因狀語，置于謂語之后的是地點、方式、原因、目的、時間和伴隨狀語。一般

5、過去時和現(xiàn)在完成時的區(qū)別.時間上有差異一般過去時與現(xiàn)在沒有關(guān)系，與表示過去的時間狀語連用，如:ago，last year，just now，the other day等?，F(xiàn)在完成時與現(xiàn)在有關(guān)系,不能與表示過去的時間狀語連用。如:He has come back home.（說明現(xiàn)在他在家。）He came back home last year.（只能說明他去年回來過,不能說明他現(xiàn)在在不在家，可能后來又出去了,但至今未歸。).結(jié)果上有差異現(xiàn)在完成時和一般過去時都表示在過去完成的動作，現(xiàn)在完成時強調(diào)對“現(xiàn)在”的影響和結(jié)果，動作到現(xiàn)在剛完成或還在繼續(xù)。一般過去時強調(diào)動作發(fā)生在“過去”，和現(xiàn)在沒有關(guān)

6、系?！净顚W(xué)活用】 單項選擇1）She _the piano for six years，but she doesnt play now.A. have playedB.playedC.has played答案：B從后半句可以判斷她已經(jīng)不再彈鋼琴了，說明前面的動作和現(xiàn)在已經(jīng)沒有關(guān)系，只是單純地陳述過去的事情，所以用一般過去時。2）We _ the museum yesterday.A. visitedB.visitC.have visited答案：A有明顯的過去時間狀語yesterday，可以判斷用一般過去時。3）I _ stamps since I was ten years old.A. c

7、ollectedB.have collectedC.am collecting答案：Bsince“自從”是現(xiàn)在完成時的一個標(biāo)志性詞語，表示動作從某時開始一直延續(xù)，所以用現(xiàn)在完成時。4）I _ to school yesterday because I was ill.A. wentB.havent goneC.didnt go答案：C全句為因果關(guān)系，應(yīng)該是“生病沒有上學(xué)”，所以否定A項；陳述昨天的事情，沒提到和現(xiàn)在的關(guān)系，所以應(yīng)用一般過去時。5）I _ in Beijing for ten years.A. livedB.have livedC.has lived答案：B句意為“我住在北京已經(jīng)

8、十年了”，沒有任何其他提示，表示現(xiàn)在仍住在北京。典題精講經(jīng)典例題在對話的空格處填上適當(dāng)?shù)膯卧~，使對話完整、正確，每空一詞。A: Mum，which TV program(節(jié)目）are you 1?B:Oh，Im watching a Beijing Opera.A: Is that2interesting than a football game?B:Yes，I think3.I prefer(更喜歡)a Beijing Opera4a football game.A:Er.but I dont like it. Shall we watch a cartoon5?B:OK.Which6is

9、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.從下文問話“我正在看京劇”中可以看出，上句話中問的是“看什么”。答案:watching2.從后面的than 可以看出這是一個比較級，因為interesting是個多音節(jié)形容詞。答案：more

10、3.從答語yes，可以看出是肯定的形式。答案：so4. prefer.to.“喜歡勝過”。答案：to5.提出建議“我們來看卡通片而不要看京劇和球賽”，要用一個詞表達此意。答案:instead6.從末尾的介詞“on”判斷，最愛的電視節(jié)目在哪個頻道。答案：channel7.上演或是播出,但注意主語是it，所以應(yīng)用被動語態(tài)。答案:showed8. not.anything=nothing。答案:anything9.must后面要接動詞原形，be on channel 6 “在6頻道”。答案：be10.just暗示本句應(yīng)該是現(xiàn)在完成時。答案:has黑色陷阱：本題有兩處陷阱，一是第6題，如果注意不到后面

11、的介詞on，很容易理解成“你最喜歡什么電視節(jié)目”，而本題是最喜歡的節(jié)目在哪個頻道，所以要填channel而不是program。第二處是第7題，很容易讓人憑直覺填be，說明卡通節(jié)目在第八頻道，陷阱是前面已經(jīng)有be動詞is了。所以填be 不對，并且還要注意動詞的被動語態(tài)的運用。綠色通道：解答此類題一定要先通讀全文，對對話的主要內(nèi)容有一個大概的理解，并充分利用好上下文所提供的信息，注意每一處細(xì)節(jié)，對號入座，對所填的內(nèi)容要進行檢驗，看句子是否通順，文章是否合情理。原創(chuàng)題根據(jù)表格和短文判斷正（T）誤（F）。Recently we have made a survey about the teenager

The teenagers like their hobbies because they like to learn new things and develop new skills. For example，playing fo

13、otball can make them strong and understand the importance of team work. Growing vegetables can help their family.(）1.The boys like dancing and singing.(）2.Both the boys and the girls like growing vegetables and playing table tennis.(）3.Collecting dolls can make the girls strong.(）4.Playing football

14、is a team-work sport.(）5.The boys dont like playing computer games.思路解析：1.F從圖表中可以判斷，喜歡唱歌跳舞的應(yīng)該是女孩子。2.T從圖表中可以判斷男孩和女孩都喜歡的兩項是growing vegetables和playing table tennis。3.F收集洋娃娃不是一個鍛煉體能的愛好，所以不能使人變強壯。4.T從文中的例子可以看出踢足球能使人理解團隊合作的重要性，所以應(yīng)該是一項團隊運動。5.F從圖中可以直接判斷此項描述不合文意。黑色陷阱：第4題考查理解能力，第5題考查反向思維能力。綠色通道：注意英文圖表題，一定不要落下

15、任何一個細(xì)節(jié)，要從細(xì)節(jié)中發(fā)現(xiàn)東西，也可以帶著問題去讀表。巧學(xué)法園地come out 一詞多義太陽星星升起，花兒綻放，消息傳出，新書出版，均用come out。Module 2Friendship語法剖析活用賓語從句在復(fù)合句中用作賓語的從句叫做賓語從句。它是眾多從句中的一員，在復(fù)合句中作主句謂語動詞、介詞或某些形容詞的賓語。.賓語從句的引導(dǎo)詞1.陳述句充當(dāng)賓語從句時，用that引導(dǎo)，that無詞義，在口語或非正式文體中常省略。如：My teacher said I was a good boy.老師說我是個好男孩。2.當(dāng)由一般疑問句充當(dāng)賓語從句時，用if或whether引導(dǎo)，意為“是否”。如：I

16、 am not sure if you are right.我不確信你是否正確。3.如果賓語從句原來是特殊疑問句，只需用原來的疑問詞引導(dǎo)。如：I want to know where he came from.我想知道他從哪里來。.賓語從句的語序必須是陳述語序句式連詞語序例句陳述句That不變I think that we can be good friends.一般疑問句if/whether改為陳述語序I cant remember if I posted the letter.特殊疑問句特殊疑問詞改為陳述語序He asked who was our English teacher.賓語從句

17、與主句的時態(tài)要相互呼應(yīng)主句是現(xiàn)在或?qū)頃r態(tài)時，從句可用任何所需要的時態(tài)。主句是過去時態(tài)時，從句要用表示過去的相應(yīng)的時態(tài)。但如果從句中有明確表示過去的時間狀語，則從句應(yīng)用一般過去時，不用過去完成時；如從句表達的是客觀規(guī)律或真理時，用一般現(xiàn)在時。如：She said that the earth moves around the sun.她說地球圍繞太陽轉(zhuǎn)?！净顚W(xué)活用】 單項選擇1）I hope _ it will snow this winter.A. whenB.ifC.whetherD./答案：Dhope 后面應(yīng)該接that引導(dǎo)的賓語從句，that 在句中沒有任何意義，可以省略。2)I do

18、nt know _ Mr.Green will come to see us.He will help us with our English.A.whyB.whenC.howD.where答案：A從下文的答語看，上文不知道的應(yīng)該是“來看我們的原因”。3)I cant remember _ I have seen him before.A.whetherB.whyC.whatD.how答案：A本句表達一種不確定的概念，用whether或if。4)Do you know _？Im going to see him.Sorry，I dont know.A.where does Mr.Li live

19、B.where did Mr.Li liveC.where Mr.Li livesD.where Mr.Li lived答案：C賓語從句要用陳述語氣，排除A、B兩項。從句意判斷問的是“現(xiàn)在住哪兒？”。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是插入語，可以把它去掉，分析句意應(yīng)該用應(yīng)用過去時態(tài)和陳述語序。6)I cant understand _ he likes computer games so mu

20、ch.A.thatB.whetherC.whyD.where答案：C句意為“我不理解為什么他那么喜歡電腦游戲”。7)(2010北京中考大綱卷)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賓語從句要用陳述語序，由此排除A、B兩項，由last week判斷應(yīng)該用過去時態(tài)。8)(2010北京中考大綱卷)I dont

21、 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判斷，應(yīng)該用將來時態(tài)表示。典題精講經(jīng)典例題例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：注意本句中斜體部分是一本書的名字誰動了我的奶酪，本句含義是“一個讀者問書

22、店管理員這本書是不是有趣”。所以答案是D項。答案：D黑色陷阱：本題的主要陷阱是書名Who Moved My Cheese， 它本身含有一個who,容易給人造成誤解。綠色通道：在英語中，注意書名一般都是斜體的，且書名的首字母是大寫的，注意把它看成一個獨立的完整的東西。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：注意后面從句的含義是“比爾蓋茨十三歲的時候開始玩電腦”，應(yīng)該用when表示“當(dāng)時”，本句中的tha

23、t是賓語從句的引導(dǎo)詞。所以選D項。答案：D黑色陷阱：本句結(jié)構(gòu)復(fù)雜，主要陷阱設(shè)置在when 上，它在本句中起到引導(dǎo)后面的時間狀語的作用。綠色通道：做此類題，要慢慢理順?biāo)悸?，不要鉆牛角尖，當(dāng)一種含義說不通時，從另一個角度或另一個含義考慮。例3(2010江蘇蘇州中考)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：本句含義是“我想知道他們叫這些動物什么”，排

24、除B、D兩項。另外賓語從句要用陳述語序。所以選C項。答案：C黑色陷阱：本句容易譯成“他們怎樣稱呼這些動物”而錯選how，注意本句中隱含句型call sb. sth.含義是“稱呼某人”。綠色通道：解答本類題首先分析句意，確定引導(dǎo)詞，然后看好語序和時態(tài)。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：本句是轉(zhuǎn)折關(guān)系，選擇C項。答案：C黑色陷阱：本句陷阱在于選項前后都是肯定句形式，不細(xì)讀題而誤選D項。綠色通道：并列句主

25、要是根據(jù)句意來判斷前后兩句的邏輯關(guān)系，所以一定要把題讀完再作判斷。例5(2010重慶中考)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，句意為“努力學(xué)習(xí)，你會很快趕上其他同學(xué)的”，and在句中表示承接關(guān)系，所以選C項。答案：C黑色陷阱：本題的陷阱是句型，本句型區(qū)別于“祈使句or”，這個句型的含義是“，不然的話/否則”。綠色通道：祈使句后面既可以加and，也可以加or，所以要全面分析句意，再作決定。原創(chuàng)題There are more and bigger

30、ffered $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：本題的陷阱主要是數(shù)字和一些專有名稱較多，容易讓人覺得文章很難。綠色通道：做這種題，可以用“地毯式”搜索的方法，同時注意答題盡量規(guī)范和完整。巧學(xué)法園地學(xué)習(xí)賓從三注意：時態(tài)語序和連詞。時態(tài)主從要呼應(yīng)：主句若為現(xiàn)在時，從句時態(tài)隨句意；主句若為過去時，從句時態(tài)變過去；語序要用陳述序，切莫照搬疑問句。that連接陳述句，省與不省沒關(guān)系。從句若表“是否”時，if，w

32、n，hope，plan，promise，would like，want等。She promised to return in an hour.她答應(yīng)一小時后回來。有的動詞后面可以接兩種形式作賓語，表達的意思有的差別不大，有的差別很大，要根據(jù)具體情況區(qū)別對待。We should continue learning(to learn).我們應(yīng)當(dāng)繼續(xù)學(xué)習(xí)。（差別不大）I remember telling him the news.我記得告訴過他這個消息了。(已告訴)Please remember to tell him the news.記得告訴他這個消息。（未告訴）常見的意義差別較大的詞：1）re

33、member，forget，regret等接動名詞表示動作已經(jīng)發(fā)生，接不定式表示動作尚未發(fā)生。2）stop doing 表示“停止做某事”，stop to do表示“停止(某事)開始做另一件事”。3）try doing 試著做，try to do 設(shè)法、盡力做某事。4）like，hate，prefer等詞后，如果表示一般傾向，多用動名詞作賓語；如指特定的或具體某次行動，用不定式時多?！净顚W(xué)活用】 翻譯句子1）他停止吸煙了。_答案：He stopped smoking.2）我想要去長城。_答案：I want to go to the Great Wall.3）我許諾要幫他。_答案：I promi
