3、用作主語(yǔ)、表語(yǔ)等。when to leave has not been decided.何時(shí)離開還沒有決定。the question is how to find him.問(wèn)題是如何找到他。(2) why用于該結(jié)構(gòu)的注意點(diǎn)：原則上說(shuō)，why后不接不定式，不過(guò)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(zhēng)論呢？注意這類結(jié)構(gòu)通常只用于談?wù)摤F(xiàn)在和將來(lái)，不用于談?wù)撨^(guò)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(diǎn)：有些動(dòng)詞后接“how不定式”作賓語(yǔ)時(shí)，how可以省略：did you learn (how) to drive a car?你學(xué)過(guò)開車嗎？但是，有些動(dòng)詞后面接“疑問(wèn)詞how不定式”作賓語(yǔ)時(shí)，盡管其中的how在漢語(yǔ)中無(wú)需譯出，但不能將how省略。he knows how to play the piano.他會(huì)彈鋼琴。he showed her how to swim.他教她游泳。(4)“疑問(wèn)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(wèn)他晚飯后會(huì)去哪兒購(gòu)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(diǎn)：表示“感到驚訝的”用單詞 。指點(diǎn)迷津(1) amazing令人驚訝的，指物，為動(dòng)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(dòng)詞amaze的過(guò)去式和過(guò)去分詞。he is amaze

7、觀需要的“必須”用_.指點(diǎn)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(shuō)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(qǐng)來(lái)。（客觀上需要做這件事）he said that they must work hard.他說(shuō)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(shí)態(tài)的變化，而mus
