表语从句

一、什么是表语从句

先看两个句子：

Thequestionisdifficult.

（表语）

Thequestioniswhowilldoit.

（表语从句）

★定义：

表语从句在复合句中作主句的表语。

表语从句和主语指同一内容，它对主语进行解释、说明，使主语的内容具体化。

★结构：

主语+系动词+表语从句

↓↓

（引导词+简单句）

★常见的可以接表语从句的系动词有：

be,look,remain,seem等。

★从句引导词：

连接词：

that/whether/asif/asthough

连接代词：

who/whom/whose/which/what

连接副词：

when/where/why/how/because

EXAMPLES:

主语+系动词+引导词+简单句

↓↓↓↓

1.Thequestioniswhetherwecanrelyonhim.

2.Helookedasifhewasgoingtocry.

3.ThatiswhyIwaslate.

二、引导词的用法

That:

（1）that在表语从句中既不充当成分,又没有意义。

Thefactisthathehasn’tyetrecoveredfromillness.

Thereasonwhyhehastogoisthathismotherisillinbed.

（2）在表“建议，命令，要求”的名词,suggestion,request,proposal等后面的表语从句中，谓语动词用“should+动词原形”，should可省略

Mysuggestionisthatwe（should）startearlytomorrow.

Whether:

whether在表语从句中表“是否”，但不充当句子的成分。

If不能引导表语从句.如:

Whatthedoctorreallydoubtsiswhethermymotherwillrecoverfromtheseriousdiseasesoon.

Thequestioniswhetheritisworthdoing.

What:

what在表语从句中充当主语、宾语或表语，表示什么，什么样子，或所…的（人或事）。

1.Thequestioniswhatcausedtheaccident.

2.Thatmountainisnolongerwhatitusedtobe.

3.Whathetoldyouwaswhathadbeendiscussedatthemeeting.

Who:

who在表语从句中充当主语、宾语或表语，表示谁。

1.Theproblemiswhocoulddothework

2.Mytroubleiswho（whom）Icanturnto.

Which:

which在引导表语从句时,常充当定语,表语，表示其中哪一个。

如：

Ireadaboutitinsomebookoranother,butwhatIdon’tknowiswhich（book）itis.

Asif／asthough

（1）由asif,asthough引导表语从句，表示好像。

asif/though引导的表语从句常置于连系动词look,seem,sound,be,appear等后面，常用虚拟语气，表示不存在的动作或状态。

常见结构：

主语+连系动词（look/seem/appear……）+that/asif+从句。

1.Itseemsasifitwasgoingtorain.

2.Theyoungmanwithlonghairlooksasifhewereagirl.

3.Itsoundsasif/thoughsomebodywasknockingatthedoor.

（2）asif/asthough引导的表语从句如果是事实，就用陈述语气，如果与事实不符，就用虚拟语气（主句一般现在时从句就用过去式，be的话变成were。

主句是过去式，从句用过去完成时）。

1.Itlooksasifhewereherownfather.（与事实不符）

2.Darkcloudsaregathering.Itlooksasifit’sgoingtorain.

Because:

（1）当主句的主语为reason,或者是由why引导的从句时,与它们相关的表语从句用that来引导,而不能because引导;because引导表语从句时只能用于It/That/Thisis/wasbecause…句型中.

1.ThereasonwhyIwaslatewasthatImissedthetrain.

2.Iwaslate.It/That/ThiswasbecauseImissedthetrain.

（2）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….

Thereasonisthat……

When／where／why／how:

当表语从句中主语、宾语、表语具备，但是还是要表示疑问含义，可以判断句子中缺少状语，常常用相应的特殊疑问词引导，有why,when,where,how等;连接副词where,when,why,how除在句中起连接作用外，在从句中还充当时间、地点、方式、原因状语，本身具有词义。

1.That’swhereIcan’tagreewithyou.

2.ThisiswhySarawaslateforthemeeting.

3.Thisishowtheyovercomethedifficulties.

4.MystrongestmemoryiswhenIattendedanAmericanwedding.

表语从句常见句型

◆名词主语＋be＋that从句

ThefactisthatIwasinthegardenwhentherobberyhappened.

☆作主语的名词通常有表示事实、真理的名词fact,truth或表示看法观点的名词idea,opinion,belief,view,feeling,suggestion,plan等。

☆suggestion,proposal,advice,requirement等词后的表语从句要用虚拟语气（should）do。

◆名词主语＋be＋wh-疑问词引导的从句

Thetroubleiswherewecangetthethingsweneed.

◆wh-引导的主语从句＋be＋that从句

Whatsurprisedmemostwasthatallthepupilswereunusuallyquiet.

◆This/That＋be＋wh-疑问词引导的从句

ThisishowhemaketheItalianpizza.

注意意：

表语从句引导词注意事项

●表语从句中的that不能省略

●表语从句中只能用whether不能用if

●表语从句中，从句用陈述句语序

●除that外的所有引导词都有自己的意义。

●除that,whether外的所有引导词都须在从句中充当相应的成分

●在有表语从句的复合句中，主句时态和从句时态可以不一致。

●从句中含有“do”时，如果后面接有宾语，引导词要选how，如果没有宾语，要用what。

如：

ThisishowIdidmyhomeworklastnight.

ThisiswhatIdidlastnight.
