初中英語重點(diǎn)知識(shí)歸納及講解1

1、初中英語重點(diǎn)知識(shí)歸納及講解：動(dòng)詞（I）-內(nèi)容預(yù)覽：動(dòng)詞（I） 重點(diǎn)知識(shí)歸納及講解一、概述動(dòng)詞是表示動(dòng)作或狀態(tài)的詞。句子中的謂語成分是由動(dòng)詞充當(dāng)?shù)?，謂語通常是句中不可缺少的成分，因此動(dòng)詞是英語詞類中最重要的一種。動(dòng)詞可以通過本身的變化來表示動(dòng)作發(fā)生的時(shí)間以及說話人的語氣、態(tài)度等。1動(dòng)詞的種類動(dòng)詞按其詞義和在句中的作用可以分為：行為動(dòng)詞（或稱實(shí)義動(dòng)詞）、連系動(dòng)詞、助動(dòng)詞和情態(tài)動(dòng)詞。詳見下表：動(dòng)詞分類 特征 例詞 例句行 為 動(dòng) 詞 vt./vi. 表示動(dòng)作或狀態(tài)。有完整的詞義。能獨(dú)立作謂語。按其帶不帶賓語、分為及物動(dòng)詞（帶賓語）和不及物動(dòng)詞（不帶賓語）help幫助（vt.） see看見（vt.）

2、go去（vi.） fly飛（vi.） He often helps me. I can see a bird in the tree. Planes can fly.連 系 動(dòng) 詞 link v. 本身有詞義，但不能獨(dú)立作謂語，必須和表語一起構(gòu)成謂語（名詞性合成謂語） be是 look看起來 seem似乎 get變得 become變成，成為 He is an English teacher. They look the same.助 動(dòng) 詞 v. aux. 本身無詞義，不能獨(dú)立作謂語，只能和實(shí)義動(dòng)詞一起構(gòu)成謂語?？捎脕肀硎痉穸?，疑問、時(shí)態(tài)、語態(tài)、語氣等。 be; have; do; will;

3、 shall He doesn't speak English. We are playing basketball Do you have a brother?情 態(tài) 動(dòng) 詞 mod v. 本身有一定詞義，但不完整。不能獨(dú)立作謂語，只能和行為動(dòng)詞一起構(gòu)成謂語，表示說話人的態(tài)度 can; many; must; need; dare; will; would; shall; should She can speak a little English. May I come in? We must go now.注意：1）行為動(dòng)詞又可分為及物動(dòng)詞（vt.）和不及物動(dòng)詞（vi.）兩種。及物

4、動(dòng)詞作謂語，后面必須跟賓語意思才完整。不及物動(dòng)詞作謂語，后面不能跟賓語，只有加上介詞后才可接賓語。2）英語中有些動(dòng)詞常常是既作及物動(dòng)詞又作不及物動(dòng)詞；既作連系動(dòng)詞工作及物動(dòng)詞。例如：He speaks English very well. (vt.) 他英語講得好。He spoke at the meeting. （vi.）另外，動(dòng)詞按其在句中能否作謂語，又可分為謂語動(dòng)詞（finite verb）和非謂語動(dòng)詞（non-finite verb）兩大類。說明：謂語動(dòng)詞又稱限定動(dòng)詞，非謂語動(dòng)詞又稱非限定動(dòng)詞。非謂語動(dòng)詞初中階段主要學(xué)習(xí)動(dòng)詞不定式的用法。2動(dòng)詞的基本形式英語動(dòng)詞有五種基本形式，即動(dòng)詞原

5、形、過去式、過去分詞、現(xiàn)在分詞和第三人稱單數(shù)形式。如：work-worked-worked-working-works。它們的構(gòu)成及形式詳見下表。形式 構(gòu)成 例詞動(dòng)詞原形 不帶to的動(dòng)詞不定式形式（也就是詞典中一般給予的形式） be, have, do, come過去式與過去分詞（規(guī)則變化） 1在動(dòng)詞原形后加-ed 2以輔音字母+y結(jié)尾的動(dòng)詞，先將y變?yōu)閕再加-ed 3以重讀閉音節(jié)一個(gè)輔音字母結(jié)尾的動(dòng)詞，先雙寫結(jié)尾的輔音字母再加-ed workworked carrycarried stopstopped現(xiàn)在分詞 1在動(dòng)詞原形后加-ing 2以不發(fā)音的e結(jié)尾的動(dòng)詞，去掉e再加-ing 3以重讀

6、閉音節(jié)一個(gè)輔音字母結(jié)尾的動(dòng)詞，先雙寫結(jié)尾的輔音字母再加-ing 4少數(shù)幾個(gè)以ie結(jié)尾的動(dòng)詞要變ie為y，再加-ing readreading writewriting swimswimming diedying第三人稱單數(shù)形式 1在動(dòng)詞原形后加-s 2以ch, sh, s, o, x結(jié)尾的動(dòng)詞后加-es 3以輔音字母+y結(jié)尾的動(dòng)詞，先將y變?yōu)閕，再加-es 4以元音字母+y結(jié)尾的動(dòng)詞后加-s runruns teachteaches washwashes gogoes passpasses trytries staystays說明：1）詞尾-ed在清輔音后讀t；在濁輔音和元音后讀d；在t和d后

7、讀id。2）詞尾-es或-s在s 、z、t 、d 后面讀iz；在清輔音后讀s；在濁輔音及元音后讀z；在t，d后讀ts、dz。3）不規(guī)則動(dòng)詞的過去式與過去分詞則要根據(jù)不規(guī)則動(dòng)詞表逐漸記住。二、動(dòng)詞的時(shí)態(tài)在英語中，由于謂語動(dòng)作發(fā)生的時(shí)間不同，或表達(dá)不同時(shí)間存在的狀態(tài)，謂語動(dòng)詞都要發(fā)生相應(yīng)的變化。這些動(dòng)詞的變化形式就叫做動(dòng)詞的時(shí)態(tài)。初中階段主要學(xué)習(xí)，掌握以下八種時(shí)態(tài)。1一般現(xiàn)在時(shí)1）構(gòu)成動(dòng)詞一般現(xiàn)在時(shí)，除主語為單數(shù)第三人稱以外，謂語動(dòng)詞一律用原形，若主語為第三人稱單數(shù)，則謂語動(dòng)詞的詞尾應(yīng)發(fā)生變化（加-s或-es）。另外be和have有特殊的人稱變化形式。詳見下表：動(dòng)詞to be 動(dòng)詞to haveI

8、 am a student You are a student He (She) is a student. We (You, They) are students I have a pen. You have a pen. He (She) has a pen. We (You, They) have pens.2）用法a表示經(jīng)常發(fā)生的動(dòng)作、行為或存在的狀態(tài)。常用的時(shí)間狀語有：often, usually, always, every day等。I go to school every day except Sunday.除了星期日，我每天上學(xué)。There are fifty student

9、s in our class.我們班上有五十個(gè)學(xué)生。b表示主語的身份或特征。His father is a doctor.他的父親是醫(yī)生。Tom is tall.湯姆個(gè)子高。c表示一種客觀事實(shí)或普遍真理The earth is round.地球是圓的.The sun is bigger than the moon.太陽比月亮大。d在條件狀態(tài)從句和時(shí)間狀語從句中，用一般現(xiàn)在時(shí)表示將來。If you don't go soon, you'll be late.如果你不快去的話，你就要遲到了。I will wait for you until you come back.我將一直等到

10、你回來。2一般過去時(shí) 1）構(gòu)成一般過去時(shí)其謂語動(dòng)詞使用動(dòng)詞過去式形式?？隙ㄊ?否定式 疑問式一般動(dòng)詞 I (You, He, She, We, They) worked there. I (You, He, She, We, They) did not work there. Did you (I, he, she, we, they) work there?be動(dòng)詞 I (He, She, It) was there. We ( You, They) were there I (He, She, It) was not there. We (You, They) were not there

11、. Was I (he, she, it) there? Were you (we, they) there?have動(dòng)詞 I (You, He, She, We, They) had books. I (You, He, She, We, They) had not/ didn't have any books Had I (you, he, she, we, they) any books?或Did I (you, he ?)have any books?2）用法a表示在過去某一時(shí)間內(nèi)發(fā)生的動(dòng)作或存在的狀態(tài)，常與表示過去的時(shí)間狀語連用，如：yesterday, last week,

12、 an hour ago, the other day, just now, upon a time, in 1989, in the old days, when I was at middle school等。He left for Beijing yesterday morning.他昨天上午到北京去了。She wasn't at home last night.她昨晚上在家。Did you finish your work at four yesterday afternoon?你昨天下午四點(diǎn)完成工作了嗎？b表示過去經(jīng)?；蚍磸?fù)發(fā)生的動(dòng)作。I got up very early

13、at that time.我那時(shí)總是起得很早。Mary always got up too late and never had enough time for breakfast when she was at middle school.瑪麗上中學(xué)時(shí)總是起得很晚，從來都沒有足夠時(shí)間吃早飯。3一般將來時(shí)1）構(gòu)成動(dòng)詞一般將來時(shí)由助動(dòng)詞shall或will加動(dòng)詞原形構(gòu)成。shall用于第一人稱作主語，will用于第二、三人稱作主語。除英國以外的說英語的國家，在陳述句中，即使在第一人稱作主語時(shí)一般也使用助動(dòng)詞will，在英國現(xiàn)在也有這種趨勢。在口語中，shall，will?？s寫成Ill You&#

14、39;ll, We'll等。在否定句中，will not縮寫成won't shall not縮寫成shan't?？隙ㄊ?否定式 疑問式I (We) shall / will go there I (We ) shall / will not go thereShall I (we) go there?You (He, She, They) will go there You (He, She, They) will not go there Will you (he, she, they) go there?2）用法a表示將要發(fā)生的動(dòng)作行為或存在的狀態(tài)。常與表示將來的時(shí)

15、間狀語連用，如：tomorrow, next time, next year, in a few days等。I'll go and see her next Friday.我下周五去看她。He won't go there tomorrow morning.他明天上午不到那兒去。Will you do it again?你再做一遍好嗎？b有時(shí)沒有時(shí)間狀語，根據(jù)上下文判斷其謂語動(dòng)作是將要發(fā)生的。I don't know who will do it.我不知道誰將做這件事。Don't worry, he will be there on time.別著急，他會(huì)準(zhǔn)時(shí)

16、在那兒。c表示將來經(jīng)常發(fā)生的動(dòng)作。From now on I'll get up early every morning.從今以后，我每天早晨早起。注意：1）表示將要發(fā)生的動(dòng)作或存在的狀態(tài)，除了用上述的一般將來時(shí)外，還可以用be going to 來表示。be going to這個(gè)結(jié)構(gòu)表示：a即將發(fā)生的動(dòng)作；b主語打算或準(zhǔn)備要做的事；c說話人根據(jù)已有的跡象判斷即將發(fā)生的事。be going to 結(jié)構(gòu)中的be隨著句子中主語的人稱而變化。例如：We are going to learn English.我們將學(xué)習(xí)英語。How are you going to spend your hol

17、idays?你們打算怎樣度過假期？Look at these black clouds. I think it's going to rain.看這些黑云，我想天要下雨了。2）在時(shí)間狀語從句和條件狀語從句中，一般將來時(shí)要用一般現(xiàn)在時(shí)代替。例如：He will come to see you when he has time.他有空時(shí)會(huì)來看你的。They will ring you up as soon as they get back.他們一回來就打電話給你。4現(xiàn)在進(jìn)行時(shí)1）構(gòu)成現(xiàn)在進(jìn)行時(shí)由助動(dòng)詞be的人稱形式加動(dòng)詞的現(xiàn)在分詞構(gòu)成。它的肯定式，否定式及疑問式的結(jié)構(gòu)如下：肯定式 否定式

18、疑問式I am working now. I am not working now. Am I working now?You are working now. He (She) is working now. We (You, They) are working now. You are not working now. He (She) is not working now. We (You, They) are not working now. Are you working now? Is (he, she) working now? Are you (we, they) workin

19、g now?2）用法a現(xiàn)在進(jìn)行時(shí)表示說話時(shí)謂語的動(dòng)作正在進(jìn)行。Who are you waiting for?你在等誰？He knows that we are helping him now.他知道我們現(xiàn)在正在幫助他 。b在現(xiàn)階段正在進(jìn)行的動(dòng)作，但不一定說話時(shí)動(dòng)作正在進(jìn)行。The students are working on the farm there days.這些天學(xué)生們正在農(nóng)場勞動(dòng)。c有些動(dòng)詞的進(jìn)行時(shí)態(tài)還可用來表示將來時(shí)。這類動(dòng)詞有g(shù)o, come, leave, arrive, move, die等。He is coming soon.他不久就要來了。Mary is arrivi

20、ng here at 4 o/clock this afternoon.瑪麗今天下午四點(diǎn)到達(dá)這里。注意：1）表示狀態(tài)或感覺的動(dòng)詞，如：know, love, like, want, hear, see, think等，一般沒有進(jìn)行時(shí)態(tài)，因?yàn)樗鼈儾荒鼙硎菊谶M(jìn)行的動(dòng)作。但是，如果詞義發(fā)生變化，能表示一個(gè)正在進(jìn)行的動(dòng)作，也可使用進(jìn)行時(shí)態(tài)。例如：Stop, I am thinking.停下來，我正在想問題呢。2）無法延續(xù)動(dòng)作的動(dòng)詞，如：jump, begin, start, stop等一般不宜用于進(jìn)行時(shí)態(tài)。但是，若想表示動(dòng)作反復(fù)或即將發(fā)生，也可使用進(jìn)行時(shí)態(tài)。例如：He is jumping up a

21、nd down.他一下一下地跳個(gè)不停。5現(xiàn)在完成時(shí)1）構(gòu)成現(xiàn)在完成時(shí)由have的人稱形式加動(dòng)詞的過去分詞構(gòu)成。它的肯定式、否定式及疑問式如下：肯定式 否定式 疑問式I (We, You, They ) have done it. He (She) has done it. I (We, You, They) have not done it. He (She) has not done it. Have you (they, I , we) done it? Has he (she) done it?2）用法a表示過去某一時(shí)間發(fā)生的動(dòng)作或存在的狀態(tài)，對現(xiàn)在仍有影響。 She has been

22、ill for three days.她病了三天了。He has already left.他已經(jīng)走了。b表示從過去某一時(shí)間開始一直持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)。We've known each other since we were children.我們從小就認(rèn)識(shí)。注意：在用already, always, yet, just, ever, never等副詞作狀語時(shí)，或者由for, since引起的短語作狀語或狀語從句時(shí)，句子的謂語動(dòng)詞常用現(xiàn)在完成時(shí)。區(qū)別：1）have (has) been to 與have (has) gone tohave (has) been to +某地，表示到

23、過某地，說明去過某地，說話時(shí)已經(jīng)回來了。have (has) gone to +某地，說明去某地了，說話時(shí)還沒有回來。例如：He has been to Beijing three times.他去過北京三次。He has gone to Shanghai.他去上海了。2）have (has) been to do sth. 還可以表示做過某事。have (has) gone to do sth.則表示去做某事了。例如：He has been to see Tom in the hospital.他去醫(yī)院看過湯姆。He has gone to see Tom in the hospital.他

24、到醫(yī)院看湯姆去了。3）have got雖然在形式上是現(xiàn)在完成時(shí)，卻和have是相同的意思。例如：Have you got any book?=Do you have any book?你有書嗎？6過去進(jìn)行時(shí)1）構(gòu)成過去進(jìn)行時(shí)由be動(dòng)詞的過去式加動(dòng)詞的現(xiàn)在分詞構(gòu)成。2）用法過去進(jìn)行時(shí)主要表示過去某個(gè)時(shí)刻或過去一段時(shí)間正在進(jìn)行的動(dòng)作。過去進(jìn)行時(shí)常與表示過去的時(shí)間狀語如：then at that time, once, a moment ago等連用，或者用另一動(dòng)作表示過去的時(shí)間。例如：I was writing a letter at home at seven yesterday evening

25、.我昨晚七點(diǎn)在家寫信。He was watching TV when I came home yesterday evening. 昨天晚上回家時(shí)，他在家看電視。7過去完成時(shí)1）構(gòu)成過去完成時(shí)由助動(dòng)詞had加動(dòng)詞的過去分詞構(gòu)成。2）用法過去完成時(shí)表示過去某一時(shí)間以前或過去某一動(dòng)作以前已完成的動(dòng)作，即過去的過去。為了更容易理解過去完成時(shí)的時(shí)間概念，使之與過去時(shí)有明顯的區(qū)別，可見下面的時(shí)間示意圖。例如：I had learned eight hundred English words by the end of last year. （在過去某一時(shí)間之前）到去年年底之前，我已經(jīng)學(xué)會(huì)了八百個(gè)英語單詞

26、。He had finished his work before I came here.（在過去另一動(dòng)作之前）在我來這兒以前，他已經(jīng)完成了工作。說明：1）在包含when, as soon as, before, after, until等連詞的復(fù)合句中，若主句謂語和從句謂語所表示的過去的動(dòng)作是在不同時(shí)間發(fā)生的，那么，先發(fā)生的動(dòng)作用過去完成時(shí)，后發(fā)生的動(dòng)作用一般過去時(shí)。例如：I told them after you had left.你走后我就告訴了他們。I had been at the bus stop for twenty minutes when a bus finally came

27、.我在公共汽車站等了二十分鐘，汽車終于來了。2）如果主句動(dòng)作和從句動(dòng)作緊接著發(fā)生，特別是連詞為after或before時(shí)，由于連詞本身很清楚地表明了動(dòng)作發(fā)生的先后，兩個(gè)動(dòng)作此時(shí)都可使用一般過去時(shí)來表示。例如：After we said good-bye to them, we left the village.在和他們告別后，我們就離開了村莊。8過去將來時(shí)1）構(gòu)成過去將來時(shí)由助動(dòng)詞should或would加動(dòng)詞原形構(gòu)成。第一人稱用should，其他人稱用would。但目前在美、英等國也有第一人稱用would的情況。2）用法a過去將來時(shí)是個(gè)相對的時(shí)態(tài)，主要用于從過去某一時(shí)間來看將要發(fā)生的事情。常

28、用在賓語從句中表示從句的動(dòng)作發(fā)生在主句動(dòng)作之后。They said they would go to visit the second factory.他們說他們將要去參觀第二個(gè)工廠。The teacher told us that there would be a concert the next Tuesday.老師告訴我們下周二將要有場音樂會(huì)。b過去將來時(shí)也可由“was / were going to + 動(dòng)詞原形”來表示。She said she was going to see her uncle.她說她要去看望她的叔叔。c有些動(dòng)詞的過去進(jìn)行時(shí)也可表示過去將來時(shí)。這一用法與某些動(dòng)詞的

29、現(xiàn)在進(jìn)行時(shí)表示一般將來時(shí)的用法相同。I didn't have much time to talk with you became I was leaving for Shanghai in two hours.我沒有多少時(shí)間跟你談話了，因?yàn)樵龠^兩個(gè)小時(shí)我就要?jiǎng)由砣ド虾！Ｗ⒁猓骸皐ould+動(dòng)詞原形”有時(shí)并不表示過去將來時(shí)，而表示一種客氣的請求。例如：Would you please open the window?請把窗子打開好嗎？三、隨堂監(jiān)測A組單項(xiàng)選擇：1.
