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.
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.
