幸福。

help other. 他虽是个孩子，却
知道帮助别人。
【说明】1、其中的动词通常为连系动词， 也就是说位于

2、如果单数名词作表语，把它提到句首时，其前不用冠词。
即使其前有形容词修饰习惯上
也不用冠词。

to play with girls.

【三条补充说明】
1. 上面提到的倒装结构有时也可用来 表示原因，区别的办
法主要看句子的内容：
让步从句的内容大多数与主句在意
义上相反，而原因从句则与主句之间有因果关系。 比较：
Tired as he was，he sat up late studying at
night.昨晚他虽然
很疲倦了，但还是学习到很晚才睡(表让步)
Tired as
he was，he went to bed early.
因为很累，所以他睡

8． 比较状语从句
常用引导词：as(同级比较), than(不同程度的比较)
（比较状语从句通常由as…as, 比较级 + than…等连词引
导。）
特殊引导词：the more ? the more ? A is to B what as X
is to Y;
no ? more than; not A so much as
B
She is as bad-tempered as her mother.
The house is three times as big as ours.
The
more you exercise, the healthier you will be.
Food is to men what oil is to machine.
食物之于人，犹如油
之于机器。
more ... than ...
引导比较状语从句表示“比??多；比??更
加??或与其说??倒不如说??”的意思。例如：
① Many companies use computers more than they
used to.
许多公司比过去更多地使用电脑。 ② In some places
bottled water costs more than a glass of
beer.在有些地方瓶
装水比一杯啤酒还贵。
③ Don’t be too hard
on him. He’s more cheated than
stupid.别对他太苟刻了，与其说他愚蠢倒不如说他被欺骗
11
了。
考题：
—Did you take
enough money with you?
—No, I needed
_________ I thought I would. （2006全国卷
Ⅱ）
A.
not so much as B. as much as
C. much more
than D. much less than
解析：
C。本题考查比较级，因为前面有no提示，故应使
用much more
than结构，意为“比??多得多”。
no
more...than从结构上来看有个变体形式是“not ... any
more
than”，表达的意思是“同??一样不??”，表达的是类
比关系；
句子在翻译时有两种方式：
先译主句后译than引导的从句，“??不能??”，就如than<
br>从句中的“不能??一样”；或者先译than引导的从句后译主
句“正如than从句中的??
不能??”，所以，“??同样不能??”。
需要注意的是than后面的句子为肯定形式，但要翻译成
否
定的意思。例如：
① The heart is no more
intelligent than the stomach, for
they are
both controlled by the
brain.心脏和胃一样都不具
有智慧，因为他们都要受大脑控制。
② Jack is
no more diligent than John. 杰克不勤奋，约翰
12
也不勤奋。
注意如下区别：
not more
... than ... 表“不如??；没有到??的程度”（前者
不如后者）。是more...
than...的否定形式。例如：
Jack is not more diligent
than John.杰克不如约翰勤奋。
He is no more fit to be
a teacher than I am.
9． 方式状语从句
常用引导词：as,
as if, as though
特殊引导词：the way
When in
Rome, do as the Roman do.
She behaved as if
she were the boss.
Sometimes we teach our
children the way our parents have
taught us.
状语从句的简化
1、状语从句同时具备下列两个条件:
①
主句和从句的主语一致，或从句主语为it；
②
②从句主要动词是be的某种形式。从句中的主语和be
动词常可省略。例如： When ( the
museum is ) completed ,
the museum will be
open to the public next year .
He’ll go to
the seaside for his holiday if (it is ) possible.
2、另外，比较状语从句经常省略。例如：
I’m taller than he
(is tall ).
13
The
higher the temperature (is), the greater the
pressure
(is ).
3、就状语从句而言,有时为了使语言言简意赅,常常将
状语
从句进行简化。状语从句的简化现象在口语中较为普遍,而且
在高考中的复现率也较高。因
此,有必要对其进行全面、透彻
的了解。
状语从句的简化现象常存在于以下五种状语从句中:
①由if,
unless等引导的条件状语从句;
②由although, though, even if
though等引导的让步状语
从句;
③由when, while, as,
before, after, until till等引导的时间
状语从句;
