第一篇:初中英語(yǔ)語(yǔ)法動(dòng)詞一教案
第8單元 動(dòng)詞(一)
(一)動(dòng)詞的種類(lèi)
動(dòng)詞是表示動(dòng)作或狀態(tài)的詞,按其詞義和在句子中的作用可分為行為動(dòng)詞,連系動(dòng)詞,助動(dòng)詞和情態(tài)動(dòng)詞。 1.行為動(dòng)詞
行為動(dòng)詞可分為及物動(dòng)詞(vt)和不及物動(dòng)詞(vi),及物動(dòng)詞表示動(dòng)作或狀態(tài),有完整的詞義,能單獨(dú)作謂語(yǔ),后跟賓語(yǔ);不及物動(dòng)詞表示動(dòng)作或狀態(tài),有完整的詞義,能單獨(dú)作謂語(yǔ),但后面不能直接跟賓語(yǔ),如要帶賓語(yǔ)則與介詞或副詞構(gòu)成短語(yǔ)?!豪华ore and more people study English.(vt) The students are listening to the teacher carefully.(vi)
2.連系動(dòng)詞
連系動(dòng)詞本身有一定的詞義,但不能獨(dú)立作謂語(yǔ),必須與表語(yǔ)一起構(gòu)成謂語(yǔ)。常用的連系動(dòng)詞有be, get, turn, become, look, feel, grow, seem, sound, taste, smell等。『例』 Our country is becoming stronger and stronger. It feels damp.
3.助動(dòng)詞
助動(dòng)詞本身無(wú)詞義,不能單獨(dú)作謂語(yǔ),只能和主要?jiǎng)釉~一起構(gòu)成謂語(yǔ)動(dòng)詞,表示否定,疑問(wèn)及動(dòng)詞的時(shí)態(tài)、語(yǔ)態(tài)、人稱(chēng)和數(shù)等語(yǔ)法特征,助動(dòng)詞有be,do,have,shall,will等?!豪?How do you usually come to school? The children are playing yo-yo now.
4.情態(tài)動(dòng)詞
情態(tài)動(dòng)詞本身有一定的意義,但不能獨(dú)立作謂語(yǔ),只能和主要?jiǎng)釉~原形一起構(gòu)成謂語(yǔ),表示說(shuō)話人的語(yǔ)氣和情態(tài)。情態(tài)動(dòng)詞沒(méi)有人稱(chēng)和數(shù)的變化。情態(tài)動(dòng)詞有can(could),may(might),must, need, ought to, dare等?!豪?Can I help you?-Must we go now? –No, you needn’t.a.can與be able to的用法有所區(qū)別。can只用于一般現(xiàn)在時(shí)和過(guò)去時(shí),指本身有能力的“能”;be able to用于各種時(shí)態(tài)均可,指須經(jīng)過(guò)努力而“能”。
b.must與have/has to的用法。must表示說(shuō)話人主觀認(rèn)為“必須”,只用于一般現(xiàn)在時(shí)和一般將來(lái)時(shí);have/has to表示客觀需要,意為“不得不”,它可用于各種時(shí)態(tài)。 c.need和dare既可作情態(tài)動(dòng)詞也可作行為動(dòng)詞。
(二)動(dòng)詞不定式
動(dòng)詞不定式to do沒(méi)有人稱(chēng)和數(shù)的變化,在句中不能獨(dú)立作謂語(yǔ),但可以和助動(dòng)詞或情態(tài)動(dòng)詞構(gòu)成謂語(yǔ),又可以在句子中作賓語(yǔ)、賓語(yǔ)補(bǔ)足語(yǔ)、狀語(yǔ)、定語(yǔ)、主語(yǔ)、表語(yǔ)等。但它畢竟是動(dòng)詞,因此,具有動(dòng)詞的許多特點(diǎn),如它可以有自己的賓語(yǔ)或狀語(yǔ)構(gòu)成不定式短語(yǔ)。
1.作主語(yǔ):
『例』To learn English is very important. 但實(shí)際上不定式作主語(yǔ)常用it來(lái)作形式主語(yǔ),而將不定式移至謂語(yǔ)動(dòng)詞后作真正的主語(yǔ)。如上句可表達(dá)為:It's very important to learn English.
2.作表語(yǔ):
『例』 My idea is to ring him up at once.
3.作賓語(yǔ):
『例』 I have decided to go to Binjiang Primary School.
4.作賓語(yǔ)補(bǔ)足語(yǔ):
a.ask, want, teach, tell, know, would like, allow等動(dòng)詞后面接動(dòng)詞不定式作賓語(yǔ)補(bǔ)足語(yǔ)。『例』The policemen asked him to get off the bus.
b.hear, see, look at, feel, watch, notice, listen to等動(dòng)詞后接不帶to的動(dòng)詞不定式作賓語(yǔ)補(bǔ)足語(yǔ)。
『例』 We often see Miss Li clean the classroom.
c.let, make, have這些使役動(dòng)詞后接不帶to的動(dòng)詞不定式作賓語(yǔ)補(bǔ)足語(yǔ)。但在被動(dòng)語(yǔ)態(tài)中這些不帶to的都須帶上to。
『例』In those days the bosses often made the workers work day and night.d.動(dòng)詞help接動(dòng)詞不定式作賓語(yǔ)補(bǔ)足語(yǔ),可帶to也可不帶to。『例』Can you help me(to)carry the heavy bag?
5.作定語(yǔ)。
a.與被修飾詞有動(dòng)賓關(guān)系。如:I have something important to tell you.但如果不定式動(dòng)詞為不及物動(dòng)詞,后面的介詞千萬(wàn)不要省略。
『例』 Maybe they have three rooms to live in. b.與被修飾詞有主謂關(guān)系。
『例』 Mr Liang is always the first to come and the last to leave. c.與被修飾之間只有修飾關(guān)系。
『例』 I have no time to play cards.
6.作狀語(yǔ),表示目的、原因、方法、方向、結(jié)果等。『例』 I'll go to meet my friend at the railway station.
7.不定式復(fù)合結(jié)構(gòu)“for sb.to do sth” 作主語(yǔ)時(shí),常用“It is +adj+ for sb.to do sth” 的句式。It is interesting(difficult, hard, easy, important, dangerous, important, possible, late , time)for sb to do sth.『例』It's dangerous for you to ride so fast. It's very kind of you to help me.It is interesting for us to read this story.It’s late for me to have class.It is important for her to stay at school.形容詞good, bad, polite, unkind, kind, ice, clever, right, wrong, careful等用“It is +adj +of sb.to do sth.” It is kind(nice good careful careless)of sb to do sth.其他形容詞用for。『例』 It is very kind of you to give me a hand.It is careless of him to do exercises.8.動(dòng)詞不定式與疑問(wèn)句who, what, which, when, how, where, whether等連用?!豪籌 don't know when to start.= I don't know when we'll start. He didn't tell me where to go.=He didn't tell me where he would go.I don’t know where to go.We knew who(whom)to ask.He wants to know what to do.I want to know why to stand there.
I didn’t know how to when to leave.Do you know how to answer this question? 注意:
a.有些動(dòng)詞或動(dòng)詞短語(yǔ)不能帶不定式,只能接動(dòng)詞的-ing形式。
如:enjoy, finish, keep, mind, miss(錯(cuò)過(guò)),be busy, go on, keep on, be worth, practise等?!豪?The peasants are busy picking apples. Would you mind my opening the door?
b.有些動(dòng)詞后可接不定式,也可接動(dòng)詞的-ing形式,但意思不同?!豪?Lu Jian forgot to post the letter.(該寄但還沒(méi)做) Lu Jian forgot posting the letter.(已經(jīng)寄過(guò)信了)
They stopped to sing a song.(停止在做的工作而去做另一件工作) They stopped singing.(停止正在做的工作)
9.不定式的否定形式:
在to 前加not.(not to do sth.)
『例』 Ask her not to speak loudly.We found people not to throw it about.Tell the students not to make much noise.10.let , make, have,had better=’d better,will you please= would you please= could you
please(跟動(dòng)詞原形,否定式是在第二個(gè)動(dòng)詞原形前加not)
『例』 Let’s go.Let me see.Li Feng made the baby stop crying.Don’t have them be in trouble.You had better turn the radio down.Will you please sweep the floor?

第二篇:初中英語(yǔ)語(yǔ)法動(dòng)詞三教案
第10單元 動(dòng)詞(三)
當(dāng)謂語(yǔ)表示一個(gè)動(dòng)作時(shí),它與主語(yǔ)有兩種不同的關(guān)系。若主語(yǔ)為動(dòng)作的執(zhí)行者時(shí),主謂之間是主動(dòng)關(guān)系,用主動(dòng)語(yǔ)態(tài);主語(yǔ)為動(dòng)作的承受者時(shí),主謂之間是被動(dòng)關(guān)系,用被動(dòng)語(yǔ)態(tài)。
被動(dòng)語(yǔ)態(tài)是由助動(dòng)詞be加及物動(dòng)詞的過(guò)去分詞構(gòu)成,由助動(dòng)詞來(lái)表示不同的時(shí)態(tài)。過(guò)去分詞的構(gòu)成分規(guī)則與不規(guī)則兩部分,規(guī)則動(dòng)詞的過(guò)去分詞變化同動(dòng)詞的過(guò)去式.(一)幾種不同的被動(dòng)語(yǔ)態(tài)的結(jié)構(gòu) 1.一般現(xiàn)在時(shí)的被動(dòng)結(jié)構(gòu): be(isamare)+及物動(dòng)詞的過(guò)去分詞 『例』 This desk is made of wood and metal. English is spoken by more and more people.2.一般過(guò)去時(shí)的被動(dòng)結(jié)構(gòu): was/were+及物動(dòng)詞的過(guò)去分詞

『例』The classroom must be kept clean and tidy every day.
The book can't be taken out of the reading room.注意:以上三種被動(dòng)結(jié)構(gòu)是初中階段的重點(diǎn),但初中階段同時(shí)也出現(xiàn)了其他結(jié)構(gòu)。見(jiàn)下面。
4.一般將來(lái)時(shí)的被動(dòng)結(jié)構(gòu):
『例』
An English party will be held on New Year's Day.
Our TV set won't be mended until next Tuesday. 5.現(xiàn)在進(jìn)行時(shí)的被動(dòng)結(jié)構(gòu):

The old man has been sent to the hospital.
注意:在初中階段還出現(xiàn)的另三種時(shí)態(tài)的被動(dòng)語(yǔ)態(tài),要求理解。7.過(guò)去進(jìn)行時(shí)的被動(dòng)結(jié)構(gòu):
was/were + being + 及物動(dòng)詞的過(guò)去分詞 『例』

『例』
He said the machine would be invented soon.9.過(guò)去完成時(shí)的被動(dòng)結(jié)構(gòu): had+been+及物動(dòng)詞的過(guò)去分詞
『例』When I remembered and went back for it, the bag had been taken away by someone.(二)被動(dòng)語(yǔ)態(tài)的用法
1. 當(dāng)我們不知道誰(shuí)是動(dòng)作的執(zhí)行者,或者沒(méi)有必要指出誰(shuí)是動(dòng)作的執(zhí)行者時(shí)。

『例』

『例』 a.Someone will give me a call tomorrow morning.
I will be given a call tomorrow morning.

This kind of sweat is selling well.
再如有些不定式表示性質(zhì)和可能性的形容詞hard, easy, possible等或用于too...to, enough to結(jié)構(gòu)中也表達(dá)被動(dòng)意義。

第三篇:初中英語(yǔ)語(yǔ)法動(dòng)詞二教案
第9單元 動(dòng)詞(二)
英語(yǔ)動(dòng)詞有十六種時(shí)態(tài),但初中階段常用的有八種,即:一般現(xiàn)在時(shí)、現(xiàn)在進(jìn)行時(shí)、現(xiàn)在完成時(shí)、一般將來(lái)時(shí)、一般過(guò)去時(shí)、過(guò)去進(jìn)行時(shí)、過(guò)去將來(lái)時(shí)和過(guò)去完成時(shí)。
1.一般現(xiàn)在時(shí)
(1)一般現(xiàn)在時(shí)主要由動(dòng)詞原形表示,但在第三人稱(chēng)單數(shù)時(shí),謂語(yǔ)動(dòng)詞在詞尾要加s或es,規(guī)則如下:
a.一般動(dòng)詞在詞尾加-s(讀音規(guī)律同名詞變復(fù)數(shù)),如:play-plays [],like-likes []
b.以字母s,x,ch,sh和o結(jié)尾的動(dòng)詞加-es,如:wash-washes [w], teach-teaches [:]
c.以“輔音字母+y”結(jié)尾的動(dòng)詞,先變y為i,再加-es,如:study-studies, fly-flies
(2)一般現(xiàn)在時(shí)的用法:
a.表示經(jīng)常性或習(xí)慣性的動(dòng)作。
『例』 He gets up early every day. b.表示主語(yǔ)具備的性格、特征和能力等。
『例』 The Changjiang River is the longest river in China. c.表示客觀事實(shí)和普遍真理。
『例』 The sun rises in the east.
d.在時(shí)間、條件狀語(yǔ)從句中表示將來(lái)的動(dòng)作。
『例』 I'll tell her about it as soon as she comes back.
2.現(xiàn)在進(jìn)行時(shí)
現(xiàn)在進(jìn)行時(shí)表示說(shuō)話時(shí)或目前正在進(jìn)行的動(dòng)作。它由“助動(dòng)詞be(am,is,are)+現(xiàn)在分詞”構(gòu)成。
『例』
The students are singing and dancing now.
現(xiàn)在分詞構(gòu)成如下:
a.一般情況詞尾加-ing,如:look-looking, read-reading
b.以不發(fā)音的e結(jié)尾的詞,去e再加-ing,如:ride-riding, leave-leaving
c.以重讀閉音節(jié)結(jié)尾的單詞,如果末尾只有一個(gè)輔音字母,應(yīng)先雙寫(xiě)這一輔音字母,再加-ing, 如: run-running,swim-swimming,prefer-preferring等。但是,有些動(dòng)詞的現(xiàn)在進(jìn)行時(shí)表示近期按計(jì)劃或安排要進(jìn)行的動(dòng)作,這些動(dòng)詞有g(shù)o, come, leave, start, arrive, return等?!豪籗he is coming to see me next week.
3.現(xiàn)在完成時(shí)
現(xiàn)在完成時(shí)由助動(dòng)詞have/has+過(guò)去分詞構(gòu)成。動(dòng)詞過(guò)去分詞的構(gòu)成規(guī)則變化同它的過(guò)去式.
(1)現(xiàn)在完成時(shí)的用法:
a.表示過(guò)去發(fā)生的某一動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果。
『例』 We have already seen this film.
The plane hasn't arrived yet.
注意:already,just用于肯定句,yet用于疑問(wèn)句或否定句。
b.表示過(guò)去已經(jīng)開(kāi)始,持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài),往往和表示一段時(shí)間的狀語(yǔ)連用,如for a week, since ten years ago等。
『例』 I have lived here since I was born.
He has worked in Shanghai for more than five years.
注意:有些動(dòng)詞代表一個(gè)短暫的動(dòng)作,因而它在現(xiàn)在完成時(shí)中不能與表示一段時(shí)間的狀語(yǔ)連用,它們有:begin, start, come, go, buy,sell, die, open, close, join, borrow等。
『例』
His grandfather has died for ten years.由于die是個(gè)短暫性動(dòng)詞不能與表示一段時(shí)間的狀語(yǔ)連用,這就要用be來(lái)表示連續(xù)狀態(tài): 『例』 His grandfather has been dead for ten years.列舉數(shù)例將短暫性動(dòng)詞轉(zhuǎn)換為延續(xù)性動(dòng)詞的表達(dá)法: Buy---have die---be deadfinish/end----be over join----be in/be+a+名詞
fall in/get ill—be ill leave/move----be away from/be out of go out----be out
get up----be up get to know-----know
(2)have/has been to與have/has gone to的用法區(qū)別:
have/has been to表示去過(guò)某地現(xiàn)在已經(jīng)返回,表示人已回來(lái)。
have/has gone to表示去某地了,可能已經(jīng)到達(dá),也可能在去的路上,表示人不在這兒?!豪华ぁ猈here's Jim? —He's gone to Xi'an. I have been to Xi'an.
(3)現(xiàn)在完成時(shí)與一般過(guò)去時(shí)的區(qū)別:
現(xiàn)在完成時(shí)表示某一完成的動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果,強(qiáng)調(diào)的是現(xiàn)在的狀況,所以它不能和確定的表示過(guò)去的時(shí)間狀語(yǔ)連用。
一般過(guò)去時(shí)只單純表示過(guò)去的動(dòng)作或狀態(tài),和現(xiàn)在不發(fā)生聯(lián)系,它可以和確定的表示過(guò)去的時(shí)間狀語(yǔ)連用。
『例』 I have read this book.(我了解書(shū)的內(nèi)容) I read this book last year.(說(shuō)明去年看的)
4.一般將來(lái)時(shí)
一般將來(lái)時(shí)由助動(dòng)詞shall/will加動(dòng)詞原形構(gòu)成。shall(用于第一人稱(chēng),will用于任何人稱(chēng)。表示將來(lái)某個(gè)時(shí)間要發(fā)生的動(dòng)作或存在的狀態(tài),常與表示將來(lái)的時(shí)間連用。如:tomorrow, next week等。但在表示準(zhǔn)備、計(jì)劃、打算做某事時(shí),常用be going to加動(dòng)詞原形的結(jié)構(gòu)?!豪?We're going to see Uncle Wang tomorrow.
5.一般過(guò)去時(shí)
一般過(guò)去時(shí)由動(dòng)詞的過(guò)去式表示,表示過(guò)去發(fā)生的動(dòng)作或狀態(tài)。過(guò)去式分為規(guī)則變化和不規(guī)則變化。
規(guī)則變化:
6.過(guò)去進(jìn)行時(shí)
過(guò)去進(jìn)行時(shí)由was/were加現(xiàn)在分詞構(gòu)成,表示過(guò)去某個(gè)時(shí)刻或某一階段正在進(jìn)行的動(dòng)作。常與表示過(guò)去某一時(shí)間的狀語(yǔ)或when引導(dǎo)的謂語(yǔ)動(dòng)詞是一般過(guò)去時(shí)的時(shí)間狀語(yǔ)從句連用。
『例』
What were you doing at this time yesterday? My mother was cooking when I got home.
7.過(guò)去將來(lái)時(shí)
過(guò)去將來(lái)時(shí)由should/would加動(dòng)詞原形或was/were going to加動(dòng)詞原形構(gòu)成,表示從過(guò)去某時(shí)看來(lái)將要發(fā)生的事情,常用在賓語(yǔ)從句中。 『例』
I didn't know when he would come back.
8.過(guò)去完成時(shí)
過(guò)去完成時(shí)由had加過(guò)去分詞構(gòu)成,表示過(guò)去某一動(dòng)作或時(shí)間以前已發(fā)生或完成的動(dòng)作,也可指從過(guò)去某時(shí)開(kāi)始到過(guò)去另一時(shí)為止的動(dòng)作或狀態(tài),即“過(guò)去的過(guò)去”。常用的時(shí)間狀語(yǔ)有:
A.by last month, by the end of last term等; B.before he came here, when I got there.『例』 By the end of last term they had learned about twenty English songs. The film had already begun when we got there.

before表示“距過(guò)去某時(shí)…以前”,即過(guò)去的過(guò)去,用于過(guò)去完成時(shí); ago表示“距今…以前”,即從現(xiàn)在起的過(guò)去,用于一般過(guò)去時(shí)。

典型例題
(1)---Do you know our town at all?---No, this is the first time I ___ here.A.was B.have been C.came D.am coming 答案B.This is the first time 后面所加從句應(yīng)為現(xiàn)在完成時(shí),故選B。(2)---Have you ____ been to our town before?---No, it's the first time I ___ here.A.even, come B.even, have come C.ever, come D.ever, have come 答案D.ever意為曾經(jīng)或無(wú)論何時(shí),反意詞為never,此兩詞常用于完成時(shí)。注意: 非延續(xù)性動(dòng)詞的否定形式可以與表示延續(xù)時(shí)間的狀語(yǔ)連用。即動(dòng)作不發(fā)
生的狀態(tài)是可以持續(xù)的。(錯(cuò))I have received his letter for a month.(對(duì))I haven't received his letter for almost a month.11.12 比較since和for Since 用來(lái)說(shuō)明動(dòng)作起始時(shí)間,for用來(lái)說(shuō)明動(dòng)作延續(xù)時(shí)間長(zhǎng)度。

I worked here for more than twenty years.(我現(xiàn)在已不在這里工作。)I have worked here for many years.(現(xiàn)在我仍在這里工作。)注意:用句型轉(zhuǎn)換的方法,很容易排除非延續(xù)動(dòng)詞在有for/since結(jié)構(gòu)的完成時(shí)中的誤用。
1)(對(duì))Tom has studied Russian for three years.= Tom began to study Russian three years ago, and is still studying it now.2)(錯(cuò))Harry has got married for six years.= Harry began to get married six years ago, and is still getting married now.顯然,第二句不對(duì),它應(yīng)改為 Harry got married six years ago.或 Harry has been married for six years.11.13 since的四種用法

延續(xù)動(dòng)詞表示經(jīng)驗(yàn)、經(jīng)歷; 瞬間動(dòng)詞表示行為的結(jié)果,不能與表示段的時(shí) 間狀語(yǔ)連用。例如:
He has completed the work.他已完成了那項(xiàng)工作。(表結(jié)果)I've known him since then.我從那時(shí)起就認(rèn)識(shí)他了。(表經(jīng)歷)2)用于till / until從句的差異
延續(xù)動(dòng)詞用于肯定句,表示“做……直到……” 瞬間動(dòng)詞用于否定句,表示 “到……,才……”。例如:
He didn't come back until ten o'clock.他到10 點(diǎn)才回來(lái)。He slept until ten o'clock.他一直睡到10點(diǎn)。典型例題
1.You don't need to describe her.I ___ her several times.A.had met B.have met C.met D.meet 答案B.首先本題后句強(qiáng)調(diào)對(duì)現(xiàn)在的影響,我知道她的模樣,你不用描述。
再次,several times告知為反復(fù)發(fā)生的動(dòng)作,因此用現(xiàn)在完成時(shí)。
2.---I'm sorry to keep you waiting.---Oh, not at all.I ___here only a few minutes.A.have been B.had been C.was D.will be 答案A.等待的動(dòng)作由過(guò)去開(kāi)始,持續(xù)到現(xiàn)在,應(yīng)用現(xiàn)在完成時(shí)。11.15 過(guò)去完成時(shí) 1)概念:表示過(guò)去的過(guò)去
----|----------|--------|----> 其構(gòu)成是had +過(guò)去分詞構(gòu)成。那時(shí) 以前 那時(shí) 現(xiàn)在 2)用法
a.在told, said, knew, heard, thought等動(dòng)詞后的賓語(yǔ)從句。例如: She said(that)she had never been to Paris.她告訴我她曾去過(guò)巴黎。b.狀語(yǔ)從句

注意: had hardly… when 還沒(méi)等…… 就……。例如:
I had hardly opened the door when I he hit me.我剛打開(kāi)門(mén),他就打了我。
had no sooner…than 剛…… 就……。例如: He had no sooner bought the car than he sold it.他剛買(mǎi)了這輛車(chē),轉(zhuǎn)眼又賣(mài)了。11.16 用一般過(guò)去時(shí)代替過(guò)去完成時(shí)
1)兩個(gè)動(dòng)作如按順序發(fā)生,又不強(qiáng)調(diào)先后,或用then,and,but 等連詞時(shí),多用一般過(guò)去時(shí)。例如:
