self-study,groupwork,discussion.参考“学习指导”p8和本学案,探究如下问题：1.什么是主语从句？举例说明。2.主语从句的引导词如何确定？3.whether/that引导主语从句的区别？4.it做形式主语的用法？5.that和what的区别？6.主语从句的语序问题？G1G3G5G7G9G11

自学指导，合作探究1.主语从句：做主语用的名词性从句，因其在复合句中做主语，又称主语从句，引导主语从句的有连词that，whether，连接代词who，what，which，连接副词when，where，how，why等。

wewillpaintthehousehasnotbeendecided.归纳总结：主语从句的引导词主语从句引导词的选择主要是根据从句的结构和意义来选择：1.如果从句的意义和结构完整，则用that。2.如果从句的意义和结构不完整，则根据从句的意义和结构选择相应的引导词。Thathewillwiniscertain.

Thattheearthisroundistrue.Whetherhe’llcomehereisn’tclear.Whetherthemeetingwillbeputoff

hasnotbeendecidedyet.

归纳总结：从属连词：that，whetherthat引导主语从句只起引导作用，本身无实际意义，在主语从句中不充当任何成分，但不能省略。whether表示“是否”的含义

3.whether/that引导主语从句的区别？小组展示,归纳拓展

由that引导的主语从句有时为了使句子结构平衡,避免“头重脚轻”,常用it作形式主语,而把从句放在后面。例如:

1.That

hewillrefusethispieceofadviceisimpossible.______________________________________________________________________________2.Thattheyshouldlikeeachotherisnatural._____________________________________*it为形式主语Itisnaturalthattheyshouldlikeeachother.Itisimpossiblethathewillrefusethispieceofadvice.4.it做形式主语的用法？1.______hewantsisabook.2._____hewantstogothereisobvious.

3.._____happenedisnotclear.4.

______yousaidyesterdayisright.5.

_____theearthgoesaroundthesuniswell-knowntoeverybody.whatThatWhat5.that和what的区别？小组展示,归纳拓展WhatThatthat和what的选用:that和what都可引导主语从句。但是，what除起连接作用外，还在主语从句中充当成分，可做从句的主语、宾语、或表语。而that在主语从句中不充当任何成分，只起连接作用。

找出下列句子中的错误，并总结规律例1.Whenwillhecomeisnotknown.规律:主语从句一律用陈述语序，即主语在前，谓语在后。正：Whenhewillcomeisnotknown.6.主语从句的语序问题?小组展示,归纳拓展1.哪个队伍会获胜，难以说清楚。____________________isdifficulttosay.(win)2.你是否会成功,很大程度上取决于自己。________________________largelydependsonyourself.(succeed)3.在如此大的世界里，我们能彼此相遇真是不容易。__________________________insuchabigworldisnoteasy.(meet)4.我们无法得到的似乎比我们拥有的要好的多。________________seemsmuchbetterthanwhatwehave.(get)5.我们都知道，猫捉老鼠。__________________isknowntousall.(catch)变式训练，提升能力
