1、a good read第3課時 grammar預(yù)習(xí)目標(biāo)1根據(jù)單詞表，預(yù)習(xí)課本第5456頁的單詞，能根據(jù)音標(biāo)正確拼讀這些單詞。2通過預(yù)習(xí)，了解“疑問詞十不定式”的用法。3了解must與have to的區(qū)別。預(yù)學(xué)熱身通過預(yù)習(xí)，了解本課時的單詞、短語和句型（英漢互譯）。1. hand vi._2.review n. _3.return vt._4.renew vt. _5. ask for help_ 6.on time_7._如此多有趣的書 8. _用法語9_下周五 10_等等11._在周末 12. _保持安靜13. wow, that's amazing! _14. we do not

2、have to go to school at weekends. _自主探究，請帶著下面這些問題閱讀教材。1“疑問詞不定式”結(jié)構(gòu)在句中可作哪些成分？2amazing與amazed有何區(qū)別？教材導(dǎo)讀1millie has decided what to read米莉已經(jīng)決定讀什么了。探究點：“疑問詞不定式”的結(jié)構(gòu)可用作_、_和_。指點迷津 “疑問詞不定式”結(jié)構(gòu)的用法：(1)該結(jié)構(gòu)的句法功能：“wh-詞不定式”主要用作賓語。we must think what to do我們必須考慮怎么辦。i can't decide whom to invite.我不能決定該邀請誰。除用作賓語外，還可

3、用作主語、表語等。when to leave has not been decided.何時離開還沒有決定。the question is how to find him.問題是如何找到他。(2) why用于該結(jié)構(gòu)的注意點：原則上說，why后不接不定式，不過若不定式不帶to，則可用why。why not go there at once?為什么不馬上去那兒呢？why argue with her?為什么要跟她爭論呢？注意這類結(jié)構(gòu)通常只用于談?wù)摤F(xiàn)在和將來，不用于談?wù)撨^去。你昨天為什么不打掃房間？誤：why not clean the room yesterday?正：why didn't

4、 you clean the room yesterday?(3) how用于該結(jié)構(gòu)的注意點：有些動詞后接“how不定式”作賓語時，how可以省略：did you learn (how) to drive a car?你學(xué)過開車嗎？但是，有些動詞后面接“疑問詞how不定式”作賓語時，盡管其中的how在漢語中無需譯出，但不能將how省略。he knows how to play the piano.他會彈鋼琴。he showed her how to swim.他教她游泳。(4)“疑問詞十不定式”結(jié)構(gòu)可以和復(fù)合句轉(zhuǎn)換。he asked where he would go shopping aft

5、er supper.he asked where to go shopping after supper.他問他晚飯后會去哪兒購物。同義句轉(zhuǎn)換the teacher asked us how we could help him.the teacher asked us_ _ _ him.2wow，that's amazing!哇，那太棒了！探究點：表示“感到驚訝的”用單詞 。指點迷津(1) amazing令人驚訝的，指物，為動詞amaze的現(xiàn)在分詞。amazing news令人感到驚訝的消息(2) amazed感到驚訝的，指人，為動詞amaze的過去式和過去分詞。he is amaze

6、d at the amazing news.他對這個驚人的消息感到驚訝。be amazed at/by（對）大為驚訝的i was amazed at her knowledge of english literature.她對英國文學(xué)之了解讓我很驚奇。小試身手單項選擇( )we were all_ at the_ result.a. amazing; amazing b. amazing; amazedc. amazed; amazed d. amazed; amazing3we do not have to go to school at weekends.在周末我們不必上學(xué)。探究點：表示客

7、觀需要的“必須”用_.指點迷津表示客觀需要的“必須”用have to。have to和must的區(qū)別如下：(1)兩詞都是“必須”的意思，have to表示客觀的需要，must表示說話人主觀上的看法，即主觀上的必要。my brother was very ill, so i had to call the doctor in the middle of the night.我弟弟病得很厲害，我只得半夜里把醫(yī)生請來。（客觀上需要做這件事）he said that they must work hard.他說他們必須努力工作。（主觀上要做這件事）(2) have to有人稱、數(shù)和時態(tài)的變化，而mus

8、t只有一種形式。但must可用于間接引語中表示過去的必要或義務(wù)。he had to look after his sister yesterday.昨天他不得不照顧他的妹妹。(3)在否定結(jié)構(gòu)中don't have to表示“不必”，mustn't表示“禁止”。you don't have to tell him about it你不一定要把此事告訴他。you mustn't tell him about it你一定不要把這件事告訴他。( ) you_ smoke in public.a. mustn't b. needn't c. wouldn&
