(5)让步状语从句
让步状语从句由although(though),as,even if,however,whatever,no matter who(how)...等词引导。例如:
Clever as he is,he doesn't study well.
Child as he is,he knows quite

一、反意疑问句的各种附加问句。
附加疑问句是简单句中的学习难点：
1．陈述句部分有ought to，used to时，附加问句可用oughtn't或shouldn't和didn't或 usedn't两种形式。如：
You o

1．as＋形容词原级＋as与not ＋so ／＋as形容词原级＋as这两个句型都可以被副词quite修饰。前者表示“和……一样”，是等量比较，后者表示“不及……”，为不等量比较。两个as中间通常为表示数量、程度、性质的词，如many，much，little，few，good，tall等。如：
This dress is twice as expensive as that one．这件外衣比那件外衣贵一倍。

在复合句中修饰名词或代词的从句叫定语从句。
被修饰的名词或代词叫先行词。引导定语从句的关系代词有who,whom,whose,which,that等和关系副词where,when,why等。关系代词和关系副词在定语从句中担任句子成分。
(1)由who,whom,whose引导的定语从句:这类定语从句中,who用作主语,whom用作宾语,whose用作定语。例如

(3)由that引导的定语从句:that在定语从句中可以指人或物,在从句中作主语,谓语动词或介词的宾语。(但不能放在介词后面作介词宾语。)例如:The letter that I received was from my father.注意在下面几种情况下必须用that引导定语从句:
①先行词是不定代词all,few,little,much,something,nothing,anything等。例如:
A

(4)由when,where,why引导的定语从句。例如:
I know the reason why he came late.
This is the place where we lived for 5 years.
I will never forget the day when I met Mr Liu.

(6)as引导的定语从句:
①as用作关系代词和关系副词引导限定性定语从句,并在从句中作主语、表语或状语,构成the same...as,such...as等结构。例如:I like the same book as you do.(as作宾语)I shall do it in the same way as you did.(as作状语)I want to have such a dictionary as he has.
