3..______happenedisnotclear.4.ThisisthebestTV_____ismadeinChina.5.Thefirstmuseum_____hevisitedinChinawastheHistoryMuseum.WhatThatthatWhatthat定语从句定语从句that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。注：that可引导定语从句，而what不可以。1.Itisreportedthatastormiscoming.2.Itistruethattheearthmovesaroundthesun.3.ItisapitythatImissedthetrain.4.Itdoesn’tmatterwhetherhewillcomeornot.

5.Itseemsthatitisgoingtorain.

6.Ithappenedthattheydidn’tknowmyaddress.翻译和分析下列句子

为了使句子保持平衡，常用______来代替主语从句，而把主语从句放到______，尤其是连词that引导的主语从句常用于此种句式中。请你归纳？it后面常用句型如下：It+be+名词+that从句It+be+形容词+that从句It+be+动词的过去分词+that从句It+be+不及物动词+that从句1.It’slikely/possible/important/necessary/clear

that…

很可能/重要的是…/必要的是…/很清楚…2.It’sknown/reported/thought/said

that…据说/据报道…3.Itseems/appears/happensthat…显然、明显、碰巧..4.It’sbeenannounced/declaredthat…已经通知/宣布…5.It’snowonderthat…并不奇怪/无疑…6.It’sapity/afact/commonknowledge(众所周知）/acommonsaying（俗话说）that…下列各句均有一处错误，请改正并分析原因。1.Lighttravelsfasterthansoundiscommonknowledge.2.Ifshe’scomingornotdoesn’tmattermuch.Thatthat虽无词义但引导主语从句位于句首时不能省略。Whetherif,whether都可表示“是否”,但if不能引导位于主句之前的主语从句，它可以引导位于主句之后带有形式主语it的主语从句。主语从句常见错误3.Thattheprofessorsaidisofgreatimportance.4.Wherewillthetreesbeplantedhasnotbeendecided.Whatthat引导主语从句时无词义。Whattheprofessorsaid表示“教授所说的”。将will置于trees之后。主语从句要用陈述句语序。5.Nomatterwhobreakstherulewillbepunished.6.Whenandwherethemeetingwillbeheldstillremainaquestion.引导让步状语从句时二者可互换，但引导名词性从句时只能用whoever。Whoever主语从句表示单一概念时，谓语要用单数形式。remains1.他在找什么与你无关。用主语从句翻译下列句子。2.他是否能来仍然是个问题。Whatheislookingforisnoneofyourbusiness.

Itremainsaquestionwhetherhewillbeabletocome.4.飞机何时起飞还没有宣布。3.谁告诉他们这个消息的仍然是个谜。Whotoldthemthenewsisstillamystery.Whentheplaneistotakeoffhasnotbeenannounced./Ithasnotbeenannouncedwhentheplaneistotakeoff.表语从句

表语从句是在复合句中作表语的名词性从句。放在系动词之后,一般结构是“主语+系动词+表语从句”。可以接表语从句的系动词有：1：be（being,been,am,is,are,was,were)2:feel,seem,look,appear,sound,taste,smell3:stand,lie,remain,keep,stay4:become,get,grow,turn,go,come,run,fall5:prove,turnout

Hewasill.That’swhyhewassenttothehospital.他病了，所以被送到医院来。Hewassenttothehospital.That’sbecausehewasill.他被送到医院，是因为他生病热二reason做主语时的表语从句填空:Thereasonwhywedidn'ttrusthimis______hehasoftenlied．reason做主语时，表语从句只能用that引导,不能用why引导。句型结构为：

Thereason(why…/for…)is/wasthat….
