唱和的拼音-job和work区别及用法
状语从句
状语修饰动词、形容词、副词或整个句子。通常由副词、介词短语、动词不定
式、分词和从
句等担当。例如:
1. Naturally , our
grandparents were pleased to get our phone call .
(副词)
2. We worked hard , from sunrise to
sunset . (介词状短语)
3.
To help my disabled
aunt , I spend an hour working in her house every
day . (不定式)
4. Seen from a distance , the
farmhouse looked deserted . (过去分词)
5. I know
how to light a camp fire because I had done it
before .(原因状语从句)
在复合句中修饰主句或主句中的某一成分的从句叫状语从句。状语
从句通常由从属连词或起
连词作用的词组引导,有时甚至不需要连词直接和主句连接起来。状语从句根据
它表达的意
思不同,可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等九类。
状语的位
置比较灵活,可以位于句首、句末或句中。enough用作状语修饰形容词和副词时必须后置
。
一、 时间状语从句
时间状语从句是表示时间关系的从句。可以引导时间状语从句的连
词很多,根据意义和主从句之间的时间
关系,通常可分为以下几种情况:
A when,
while, as, whenever
when, while,
as表示主句谓语作和从句的谓语动作同时发生或几乎同时发生。
1.when

got home, my family were already having dinner.
我到家的时候,全家已在吃晚饭。(when表示点时间)
When they
were still talking and laughing, the teacher came
in.

to bed when the doorbell rang.
他正要上床,忽然门铃响了。

while 意思很相近,但是during是介词,不能引导从句。

在比较从句中通常把和主句重复的部分省掉,如果把省略部分补上,而显得累赘或不合乎习惯。
Lily isn't so clever a girl as Lucy is.
莉莉是一个不如露西那样聪明的女孩。(如说成:Lily isn't so clever a girl
as Lucy is clever 显得累赘)
The child sang as
sweetly as a nightingale.这孩子歌唱得同夜莺般婉转。

这是表示比例的比较,意思是越……就越……。第一个the more 也可以看成是一个条件。

understand better.)
The busier he is, the
happier he feels.他越忙越开心。
The more difficult
the questions are, the less likely I am to be able
to answer them.问题越困难,我就越可能回答。

九、让步状语从句
让步状语从句表示在某种相反的条件下,主句中的情况依然会出现。让步状语从句由although,
though,
however, whatever, whoever, whomever,
whichever, whenever, wherever, whether(是否), no
matter (who, wha,
etc), even if, even
though等词引导。
A.although, though
这两个词意思一样,都解释虽然,尽管。although比though正式。
1.although指事实,多用于句首。多数情况下可与though换用。
Although
he is young, he is very clever.他尽管年轻,但很聪明。
Although his illness had prevented him from
studying, he managed to pas the
exam.尽管病情妨碍了他学习,但他还是通过了考试
。
It was an
exciting game, although no goals were
scored.那是一场精彩的球赛,尽管一个球都没进。(although也可放在主句之后)
2.though既指事实,又指设想。可用于句首、句中或句末。
Though he
is poor, he is happy.他虽然穷,但很快乐。
I haven't
checked the information yet, though I think it is
correct.我还没有核实这份资料,但我认为它错不了。
My house, though
it is large, is also made of stone and
wood.我的房子虽然大,但是也是用石头和木料搭成的。
提示:
有时though= and yet但是,然而,放在句子末尾,前面用逗号。
It was
hard work; I enjoyed it, though.那工作很苦,但是我喜欢干。(= It
was hard work, but I enjoyed it.)
3.though从句有时可以倒装,将从句中的一部分提置句首。
Child though
he is, he knows a lot.尽管他是个孩子,他懂得的东西却很多。
(=Although he is a child, he knows a lot.)= Child
as he is, he knows a lot
Strange though it
may look, it is true. 尽管看起来奇怪,但是却是真的。(= Though it
looks strange, it is true.)
注意:
although, though不能与but连用,但是可以与yet, still,
nevertheless连用。
AlthoughThough he blames me,
yet I will trust him.尽管他责怪我,但我还是愿意信任他。
Though
he was hungry, still he would not
eat.尽管他饿了,但是他仍然不想吃。
B.Even if, even though
这两个词语气比though, although强,解释即使,两者可以通用。
We
won't be discouraged even if though we fail ten
times.我们就是失败十次也不泄气。
Even if though you fail,
you will have gained experience.纵然你失败,你也会得到一些经验。
C.while, whereas
这两个词也可引导让步状语从句,突出主句和从句的对比。
While I understand
what you say, I can't agree with
you.虽然我理解你的意思,但我还是不同意。
Some people like fat
meat, whereas others hate it.有些人喜欢肥肉,相反有些人讨厌肥肉。
9
D.no matter (who,
what, where, when, etc)
这几个词引导的让步状语从句语气十分强烈。
This is not true, no matter who says
so.不管谁这么说,都不对。
Do it no matter what others
say.不管别人怎么说,尽管干。
No matter how bus he was, he
studied English every day.不管他多忙,他都每天坚持学习英语。
E.However, whatever, whenever, wherever
这些词在意思上和用法上都等于no matter how what
Whatever
happens may happen, we shall never lose
hope.无论发生什么,我们都不要失去信心。(有时从句中的动词与may连用)
However (=No matter how) expesive it may be, I'll
take it.无论它有多贵,我也要买下它。
Don't let them in,
whoever (=no matter who) they are.不管他们是谁,别让他们进来。
F.Whether...or (not) ...
whether...or
(not) ...意思是不管……还是……。
Whether you believe it
or not, it's true. 不管你信不信,这是真的。
Whether the
weather is good or bad, they will set off as
planned.不管天气是好还是坏,他们都要按计划启程。
提示:
也可直接用or来连接两个相同结构来表示让步。
Walking or sleeping,
she always has the question in her
mind.无论走路还是睡觉,她总是想着这个问题。
G.as
连词as,同though一样,也可以引导让步状语从句,但从句中要用特殊语序。
Young
as he is, he knows a lot.他虽然年轻,但懂得很多。(= Though he
is young, he.)
Cold as it is, the children
play outdoors.虽然天气冷,但孩子们仍在户外玩。
H.if
if
有时也可用于让步状语从句,相当于even if。
If he is poor, he is
at least honest尽管他穷,但至少他很诚实。
We'll go if it
rains.即使下雨我们也要去。
I'll do it if I die in the
attempt.即使会丧命我也要试一下。
注意:
有些时间、地点、条件、方式或让
步等状语从句中,如果谓语含有动词be,主语又和主句中的主语一致,
或者主语是it,常把从句中的
主语和谓语的一部分(特别是动词be)省略掉。
Look out for cars when
crossing the street.过街时当心车辆。(= when you are
crossing the street)
She hurriedly left
the room as though angry.她急匆匆地走出屋去,好象很生气的样子。(= as
though if she was were angry)
If possible,
I'd like to have two copies of it.可能的话,我想要两本。(= if
it is possible,)
She advised me not o say
anything unless asked.她劝我别说什么,除非有人要我说。(= unless I
was asked )
As a young man, he studied law
and became a lawyer.他年轻时就学了法律,并当了律师。
(= As
When he was a young man,)
