高中英语从句讲解与练习
(1)表语从句
1. 定义:
用作表语的从句叫做表语从句。
2. 引导表语从句的关联词的种类:
(1) 从属连词that。
在从句中不做成分。
如:
ThetroubleisthatIhavelosthisaddress.麻烦是我把他的地址丢了。
Thereasonwasthathewaslateforschool.
(2) 从属连词whether,as,asif。
如:
1.Helookedjustashehadlookedtenyearsbefore.他看起来还与十年前一样。
2.Thequestioniswhethertheywillbeabletohelpus.问题是他们是否能帮我们。
注:
从属连词if一般不用来引导表语从句,但asif却可引导表语从句,如:
Allthiswasovertwentyyearsago,butit’sasifitwasonlyyesterday.
这都是20多年前的事了,但宛如昨天一样。
Thekeyiswhetherwecansolvetheproblem.//Itlookedasifitwasgoingtorain.
注:
能跟表语从句的谓语动词一般为系动词be,seem,look,sound等。
如:
Helookedjustashehadlookedtenyearsbefore.他看起来还与十年前一样。
Itsoundsasifsomeoneisknockingatthedoor.连接代词who,whom,whose,what,which,whoever,whatever,whichever在表语从句中做主语、宾语等。
如:
Theproblemiswhowecangettoreplaceher.问题是我们能找到谁去替换她呢。
Thatwaswhatshedidthismorningonreachingtheattic.那就是她今晨上了阁楼干的。
Theproblemiswhowecangettoreplaceher.
我想问的是谁离开了。
Myquestioniswholeft.
连接副词where,when,how,why。
WhatIwonderiswhenheleft.我想知道他是何时离开的。
Thisiswheretheyoncelived.这就是他们曾经住过的地方。
Thatiswhyhedidn'tcomehere.
Thequestionishowhedidit.
(3) 连词because可引导表语从句。
如:
Ithinkitisbecauseyouaredoingtoomuch.我想这是因为你做得太多。
It'sjustbecausehedoesn'tknowher.
That'sbecausehedidn'tunderstandme.那是因为他没有理解我.(That'sbecause...强调原因)
That'swhyhegotangrywithme.那正是他对我生气的原因。
(That'swhy...强调结果)
(4) 在一些表示“建议、劝说、命令”的名词后面的表语从句中,谓语动词用虚拟语气。
should+动词原形表示,should可省略。
如:
Mysuggestionisthatwe(should)startearlytomorrow.我的建议是我们明天一早就出发。
