【文章內(nèi)容簡(jiǎn)介】 ch(ever), whom(ever), whose 2）連接副詞：when, where, why, how 3）連接詞：that, whether, if 連接代詞和連接副詞在從句中充當(dāng)一定的句子成分，而連接詞在從句中不充當(dāng)句子成分，只起連接作用名詞性從句的難點(diǎn)把握1由whoever/whatever/whichever/whomever引導(dǎo)的名詞性從句 這些詞引導(dǎo)的名詞性從句相當(dāng)于帶有定語從句的名詞詞組：whoever=anyone who?“任何??的人”；whomever是whoever的賓格形式 whatever=anything that? “任何??的物”whichever=any ? that? “任何??的（已知范圍內(nèi)的或上文提到過的）人或物” that引導(dǎo)的同位語從句與定語從句的區(qū)別：The suggestion that the students(should)have plenty of exercise is very suggestion(that/which)he raised at the meeting is very ，在從句中不充當(dāng)任何成分，因此它引導(dǎo)的是同位語從句，其中that不能省略；下句中that不僅起引導(dǎo)作用，同時(shí)在從句中還充當(dāng)了動(dòng)詞raised的賓語，因此它是定語從句，此時(shí)that可用which代替，又因其在定語從句中充當(dāng)賓語，故又可省略。2．名詞性從句中的what和that what和that的選用一直是學(xué)生學(xué)習(xí)的一個(gè)難點(diǎn)，正確選擇的關(guān)鍵是看該從句結(jié)構(gòu)是否相對(duì)完整、是否缺少主語、賓語或表語等成分而定。he said at the meeting surprised everybody he said nothing at the meeting surprised everybody problem is what we should do to protect the ear What fact is that we should do something to protect the ．名詞性從句中的whether和if 在主語從句、表語從句和同位語從句中遇“是否”句用whether引導(dǎo)而不用if；在賓語從句中whether和if?？蓳Q用。4．名詞性從句中的虛擬語氣表示“堅(jiān)持、命令、建議或要求”等詞義出現(xiàn)時(shí)，不管是在哪一種從句中，常用虛擬語氣，從句中的謂語動(dòng)詞形式為（should）+ 動(dòng)詞原形，其中should可省略。常用詞有insist, suggest, order, demand等。三． 教學(xué)步驟。帶領(lǐng)學(xué)生復(fù)習(xí)一下英語當(dāng)中的五種簡(jiǎn)單句型結(jié)構(gòu)以及主從復(fù)合句和并列句，并分清楚他們之間的區(qū)別與聯(lián)系。簡(jiǎn)單句 S + VHe + V + OHe didn’t invite + V + PI am a + V + OoHe promised me a bike as my birthday + V + O + CI want you to assist + 并列連詞+簡(jiǎn)單句→ 并列句簡(jiǎn)單句 + 并列連詞+ 主從復(fù)合句 → 并列句。從以下所給的例題中選出名詞性從句并標(biāo)明是哪種名詞性從句。 people invited to the ball may dress __ they can39。t quite remember __ you started doing the it was when it was that was it that was it when tell me ________ you would like to have your coffee, black or white? 賓從 this the factory _______ you visited the other day? 定從 which one the fact remains ________ we are behind other leave it to your own judgment _______ you should do is the museum ______ we saw an exhibition the other that that that that what has made China ____ she is today? 主從, that, what, what, that frightened us ____ two lights appeared suddenly in the 表從 was, that , most was that, mostly that, most was what are good is no wonder that they know each other so was ______ he said ______ that disappointed 主從。that。that。what。what has given us a suggestion ____ we should buy a cottage in the country with the money _________we have 定從 , what, whichC./, which, / is pleased with ____ you have given him and all ______you have told 定從, that, that, which, what reason __ we were late is __ we missed the 表從。because。that。why。that 因高三為復(fù)習(xí)課，所以在復(fù)習(xí)完基本句型的基礎(chǔ)上作此練習(xí)，可以幫助學(xué)生進(jìn)一步去熟悉句型結(jié)構(gòu)，為名詞性從句的掌握打下基礎(chǔ)。三．做題，討論，自我總結(jié)。在這一板塊，先給學(xué)生8分鐘時(shí)間完成上述題目，之后三人小組討論進(jìn)行答案分析，然后老師給出正確答案，并對(duì)學(xué)生自己無法解決的題目進(jìn)行講解。然后，再次進(jìn)入討論環(huán)節(jié)，并進(jìn)行自我總結(jié)，總結(jié)出在做名詞性從句當(dāng)中須注意的點(diǎn)。：1）連接代詞：who(ever), what(ever), which(ever), whom(ever), whose 2）連接副詞：when, where, why, how 3）連接詞：that, whether, if 連接代詞和連接副詞在從句中充當(dāng)一定的句子成分，而連接詞在從句中不充當(dāng)句子成分，只起連接作用。 whether 的區(qū)別。A 在動(dòng)詞不定式之前只能用whether。如：例8 I can’t decide whether to 。B 在whether …… or not 的固定搭配中。如：例9 I want to know whether it’s good news or 。C 在介詞后，只能用whether。如：例10 His father is worried about whether
