self-study,groupwork,discussion.參考“學(xué)習(xí)指導(dǎo)”p8和本學(xué)案,探究如下問題：1.什么是主語從句？舉例說明。2.主語從句的引導(dǎo)詞如何確定？3.whether/that引導(dǎo)主語從句的區(qū)別？4.it做形式主語的用法？5.that和what的區(qū)別？6.主語從句的語序問題？G1G3G5G7G9G11

自學(xué)指導(dǎo)，合作探究1.主語從句：做主語用的名詞性從句，因其在復(fù)合句中做主語，又稱主語從句，引導(dǎo)主語從句的有連詞that，whether，連接代詞who，what，which，連接副詞when，where，how，why等。

Thattheearthisroundistrue.Whetherhe’llcomehereisn’tclear.Whetherthemeetingwillbeputoff

hasnotbeendecidedyet.

歸納總結(jié)：從屬連詞：that，whetherthat引導(dǎo)主語從句只起引導(dǎo)作用，本身無實(shí)際意義，在主語從句中不充當(dāng)任何成分，但不能省略。whether表示“是否”的含義

由that引導(dǎo)的主語從句有時(shí)為了使句子結(jié)構(gòu)平衡,避免“頭重腳輕”,常用it作形式主語,而把從句放在后面。例如:

1.That

hewillrefusethispieceofadviceisimpossible.______________________________________________________________________________2.Thattheyshouldlikeeachotherisnatural._____________________________________*it為形式主語Itisnaturalthattheyshouldlikeeachother.Itisimpossiblethathewillrefusethispieceofadvice.4.it做形式主語的用法？1.______hewantsisabook.2._____hewantstogothereisobvious.

3.._____happenedisnotclear.4.

______yousaidyesterdayisright.5.

_____theearthgoesaroundthesuniswell-knowntoeverybody.whatThatWhat5.that和what的區(qū)別？小組展示,歸納拓展WhatThatthat和what的選用:that和what都可引導(dǎo)主語從句。但是，what除起連接作用外，還在主語從句中充當(dāng)成分，可做從句的主語、賓語、或表語。而that在主語從句中不充當(dāng)任何成分，只起連接作用。

找出下列句子中的錯誤，并總結(jié)規(guī)律例1.Whenwillhecomeisnotknown.規(guī)律:主語從句一律用陳述語序，即主語在前，謂語在后。正：Whenhewillcomeisnotknown.6.主語從句的語序問題?小組展示,歸納拓展1.哪個隊(duì)伍會獲勝，難以說清楚。____________________isdifficulttosay.(win)2.你是否會成功,很大程度上取決于自己。________________________largelydependsonyourself.(succeed)3.在如此大的世界里，我們能彼此相遇真是不容易。__________________________insuchabigworldisnoteasy.(meet)4.我們無法得到的似乎比我們擁有的要好的多。________________seemsmuchbetterthanwhatwehave.(get)5.我們都知道，貓捉老鼠。__________________isknowntousall.(catch)變式訓(xùn)練，提升能力
