高中状语从句基础知识

用作状语的句子就叫做状语从句(adverbial clause)。
状语从句通常由一个连词或起着连词作用的词组引导, 这些词或词组被称作为关联词或引导词。
状语从句同状语一样,在句中的位置比较灵活,可置于句首、句末或句中。

例如:
l Do it as you were told! 按照你被告知的那样去做!(引导词是as,从句置于句末)
l Whatever he says, just don’t believe him. 不管他说什么,你只要不相信就行了。(引导词是whatever,从句置于句首)
l Put in articles where they are necessary in the following passage. 在下列段落中需要处填入冠词。(引导词是where, 从句置于句中)
状语从句根据其表达的意思和用途不同,可分为时间状语从句、地点状语从句、原因状语从句、结果状语从句、目的状语从句、条件状语从句、让步状语从句、方式状语从句、比较状语从句等类别。

例如:
l Once you’ve finished, go to bed. 你干完了就去睡觉。(时间)
l You can borrow it as long as you’re not careless with it. 你可以借去用,只要你不乱用就行了。(让步)
l Now that you have come, you may as well stay. 既然你已经来了,你最好还是留下吧。(让步)
l Don’t move! Stay where you are! 别动!就站在那儿别动!(地点)
l They set out early so that they might arrive at the airport in time. 他们很早出发,以便及时赶到机场。(目的)
l It is such a difficult problem that nobody can work it out. 这是一个很难的问题,谁也解不出。(结果)
l He opened his lips as if he were going to say something. 他动了动嘴唇,好像要说什么似的。(方式)
l In case it rains, do not expect me. 如若下雨,就不要等我了。(条件)
l The harder you study, the more knowledge you will get. 学习越用功,得到的知识就越多。(比较)

时间状语从句拓宽知识
时间状语从句表时间,其关联词主要有:
when, while, as,
before, after,
since,
(not) until,
as soon as,
hardly/scarcely/barely…when, no sooner… than,
the minute/moment/second…,
directly/immediately,
each (every, next, the first…) time

例如:
l Soon after her mother returned, the girl went to sleep.女孩在她母亲回来后不久就睡着了。
l I have lived in Shanghai since I was a child.我从小就住在上海。
when, while和as在引导时间状语从句时都可表示“当……时候”,但互相间有区别。
when:主句和从句的动作可以是同时发生,也可以是先后发生,动词如果是指可以持续发生的动作的话,通常用进行时态来表示;when 引导的时间状语可以表示一段时间内发生的动作,也可以表示某一时间点所发生的动作。
while:主句和从句的动作基本上是同时发生的,动词如果是指可以持续发生的动作的话,通常用进行时态来表示;while 引导的时间状语只表示一段时间内发生的动作;while 也可以指两个动词间的对比,表示反差相当于but。
as: 主句和从句的动作可以是同时发生,也可以是先后发生,但强调动作是紧接着发生,表示“随着……、一边……一边、正当……”。

例如:
l While I was having dinner, he was reading a very interesting story. 当我在用餐时,他正在读一本有趣的小说。(主、从句的动作持续在一段时间内同时发生)
l I will go on a trip to Canada when I have enough money. 当我有足够的资金的时候,我会到加拿大去旅行。(主、从句的动作先后发生)
l We were having a party when the lights went out suddenly. 当灯突然熄灭的时候,我们正在开派对。(灯熄灭是突然的动作,when 在这里引导的时间状语从句是表示某一时间点所发生的动作)
l While we were watching TV, the boy came in hurriedly. 当我们在看电视时,男孩匆忙跑了进来。(主、从句的动作同时发生,可以用when来代替)
l While my mum was busy preparing supper, my dad was reading a newspaper. 当我妈妈忙于准备晚饭时,我爸爸倒在看报纸。(表示对比,可以用but来代替)
l As the pupils walked along the street, they sang happily. 学生们一边沿着街道走,一边愉快地唱歌。(主、从句的动作同时发生, 强调“一边……一边”,不可替换)
l As spring comes, everything comes to life. 春回大地,万物苏醒。(表示紧接发生的动作,“随着……”)
一些表示时间的副词和短语也可以引导时间状语从句。

例如:
l Directly the mother was out of sight of her son, she wanted to see him. 这个母亲一看不到儿子就想见他。(directly相当于as soon as)
l We’ll leave the minute you’re ready. 你准备好了我们就走。(the minute引导从句)
l The day he returned home, he found great changes had taken place in his hometown. 他回家的那一天发现家乡已发生了翻天覆地的变化。(the day引导从句)
l The first time she saw the dress, she fell in love with it. 当她第一眼看到这条裙子,她立刻就喜欢上了。(the first time 引导时间状语从句, 相当于when she saw the dress for the first time, …)
l

地点状语从句拓宽知识
地点状语从句表地点,其关联词有where, wherever, anywhere, everywhere, etc.
地点状语从句中有些部分经常可以省略。
地点状语从句经常容易和定语从句混淆。

例如:
l Corn grows best where the ground is rich. 谷物在土地肥沃的地方长得最好。
l You are able to go wherever you like. 你喜欢上哪儿就可以上哪儿。
l Everywhere you go, never forget your motherland. 无论你到哪里,都不要忘记自己的祖国。
l He would live with his grandmother anywhere she lived. 不管他的祖母住在哪儿,她都愿意和她住在一起。
l Such kind of structure should be avoided wherever (it is) possible. 像此种结构随处都得避免。(it is 可以省略)
l Fill in the blanks with the proper form of verbs where necessary.在下面的空格里,如需要使用动词的,用其恰当形式填写。(同样省略了where 之后的主谓结构)
l Please make a mark where you have a question to ask. 在你有问题需要问的地方做一个标记。(此句句子为地点状语从句,由where 来引导。 但常常被误认为定语从句, 其实假定where 引导的是定语从句的话, 该“定语从句”在意义上无法修饰其“先行词”mark)
l College graduates should go where our country most needs them. 大学毕业生应到祖国最需要他们的地方去。(还是由where 来引导的地点状语从句,如作为定语从句来理解的话,那么定语从句的先行词都没有,go 是动词。但因为常常被误认为定语从句,所以学生常会用“in which 或to which”来代替where)


原因状语从句表原因或理由,其关联词有because, as, since, in that, now that, etc.
because, as, since 均表示“因为、由于”的意思。
because 语气最强,用以回答why, 可与强调词only, just以及否定词not连用。
as 和since的语气较弱,所表示的原因比较明显,或是已知的事实,故不需要强调。它们引导的从句多置于句首,且不能用强调词修饰,也不可和否定词not 连用。as 指“由于”;since 指“既然”

例如:
l George was worried because he hadn’t had any letter from Green. 乔治很着急,因为他一直未收到格林的信。
l You shouldn’t get angry just because some people speak ill of you. 你不该仅仅因为有些人说了你的坏话就发怒。
l The man bought the expensive house easily only because his parents had given him a large sum of money. 就因为这个男的父母给了一大笔钱,所以他能轻松买下这么贵的房子。
l It was because I wanted to see my uncle that I went to town yesterday.我昨天是由于要去看我的叔叔而进城的。(because 引导的原因状语从句的强调句形式:It is (was) because …. that …, since 与 as 无此形式)
l As the bell had rung, all the students went to the classroom. 由于上课铃声响了,同学们都进了教室。
l Since you’re going, I will go too. 既然你要去,我也去吧。


结果状语从句表结果,其关联词有so, so that , so…that, such…that, with the result that, etc.
so…that常和形容词或副词连用,若有与有形容词的短语连用,则引起倒装;such…that 常和名次连用。
结果状语从句常置于主句之后。
目的状语从句表目的,其关联词有so that, in order that, lest, etc.
目的状语从句中常常有情态动词may (might), shall (should), will (would), can (could) 来表示目的。
so that 和in order that 所引导的目的状语从句可放于句首。
lest 和in case 引导目的状语从句时表示“以免、以防”的意思,一般用虚拟语气。

例如:
l They had oral practice every morning, so that they made rapid progress in their speaking. 他们每天早晨练习口语, 结果他们口语能力提高很快。
l He worked so hard that he finished his task in three days. 他工作得很努力,三天就完成了任务。
l She is such a demanding girl that it’s impossible for any other one to please her. 她是一个如此苛刻的女孩以至于不可能有人会令她满意。
l I was in the bath, with the result that I didn’t hear the telephone. 我在洗澡,所以没听见电话铃声。
l He drew a plan of the village so that she could find his house easily. 他花了一张这个村子的草图,以便于她能找到他的房子。
l In order that the grass and flowers could bloom again, it was necessary that the rocks should be removed. 为了这些花草能再开花,这些石头必须搬走。
l Take your umbrella with you, lest/in case it should rain. 带上你的伞,以防下雨。(should rain 是虚拟形式)

条件状语从句拓宽知识
条件状语从句表条件,其关联词有
if;
only if,
unless,
as/so long as; as/so far as,
provided/providing (that),
suppose, supposing,
assuming,
on condition that,
once(note: some can + ~ing/~ed): Once begun, …
in case
