状语从句是高中英语语法学习中的基础性内容之一,也是高三考试中设计比较多的知识点。那么在实际的状语从句复习过程中,需要重点掌握的内容都有哪些呢?下面沪江小编就为大家分享一些。

  一、时间状语从句

  时间状语从句由when, while, after, before, since, as soon as, till, until等连词引导。

  例如:

  I went to bed after the TV play was ever.

  电视剧完了以后我上床睡觉。

  Could you look after her while we're away?

  我们不在时你能照顾她吗?

  She has taught in this school since she came to this city in 1989.

  自从一九八九年她来到这座城市以来一直在这所学校教书。

  Wait until I come back.

  请你等到我回来。

  注意:

  如主句是一般将来时,则表示将来的时间状语只用一般现在时。

  例如:

  I'll write to you as soon as I get to Beijing.

  我一到北京就将写信给你。

  It will get warmer and warmer when spring comes.

  春天来临时,天气将变得越来越暖和。

  二、原因状语从句

  原因状语从句由because, as, since等连词引导。

  例如:

  He sold the car because it was too small.

  他卖掉那辆小汽车,因为它太小了。

  Since you won't help me, I must do the job myself.

  你既然不帮我忙,我必须自己做这项工作。

  As my mother is away at this moment, I have to look after my younger sister.

  由于我的妈妈现在不在,我不得不照顾我的妹妹。

  注意:

  a)because, as, since, for的用法辨析

  because, as, since, for都是表示各种理由的连词,但because多表示所叙述的理由是本句的重点,故because所引导的从句常放在句末。

  例如:

  Why was he absent? Because he was badly ill.

  他为什么缺度?因为他病得很重。

  as, since用于表示理由是已知,而理由以外才是叙述的重点,两者皆多用于句首,但要注意since重形式,as多表示理由以外的才是重点。

  例如:

  As it is raining, let's stay as home.

  因为下雨,我们就留在家里吧。

  Since you have no license, you are not allowed to drive.

  因为你没有驾驶执照,所以你不可以开车。

  for不用于句首,而用于主句之后,补充说明理由;主句表推测时,用for说明原因。

  例如:

  I'll follow his advice, for he is a doctor.

  我会听从他的劝告,因为他是医生。

  b)because of也是表示原因状语,但后面只能跟短语。

  例如:

  I stayed at home because of the bad weather.

  因为天气不好我留在家里。

  三、比较状语从句

  比较状语从句由than或as来引导。

  例如:

  I feel better now than (I was) before.

  我现在觉得比以前好了。

  He writes as well as you (do).

  他写得和你一样好。

  This problem is more difficult than that one (is).

  这道题比那道题难。

  四、条件状语从句

  条件状语从句由if, unless(= if not)算连词引导。条件从句中的动词多用一般现在时表示将来。

  例如:

  I shall go if he asks me.

  如果他请我,我就去。

  I shan't go unless he asks me.

  除非他请我,否则我是不去的。

  I shall go, whether he asks me or not.

  不管他请不请我,我都要去。

  Come with me if you have time.

  如果你有时间请跟我来。

  I want to watch a basketball match if I'm well tonight.

  如果今晚我好了的话,我要看一场篮球赛。

  由and连接的简单句,可以用条件状语从句来改写。

  例如:

  Run faster and you'll catch up with him.

  跑快点儿你就会赶上他。

  =If you run faster, you'll catch up with him.

  如果你跑得快点,你就会赶上他。

  五、结果状语从句

  结果状语从句由so that, so… that引导。

  例如:

  He has lost his bike so that he can't come to school on time.(结果状语)

  他去了自行车,所以不能准时到校。

  Your shirt were so dirty that you must wash it.(结果状语)

  你的衬衣这么脏,你应该把它洗洗。

  注意:

  由so…that引导的状语从句若是表示否定意思,可以用too…to(太…而不能)来替换。

  例如:

  She was so angry that she could not say a word.

  =She was too angry to say a word.

  她气得说不出话来。

  六、让步状语从句

  让步状语从句一般用though(虽然)、although(虽然)、even though(即使)引导。

  例如:

  Though/Although he tried hard, he was not successful.

  他虽然努力尝试,但没有成功。

  He went on working though it was very late.

  虽然很晚了,他还在继续工作。

  注意:

  1.汉语中的“虽然…但是…”在英语中用连词though就可以了,或单独使用but连接两个并列句也可以,但不能在一个句子中同时用这两个连词(主句前不用连词)。

  例如:

  “虽然我很喜欢照顾我姐姐的婴儿,但她不让我干”。这个句子我们可以用下面两种方法来表达。

  Though I like looking after my sister's baby, she doesn't let me do it.

  I like looking after my sister's baby, but she doesn't let me do it.

  =though可以与yet连用,这里yet虽然意思与but相同,但yet不是连词,而是副词。

  例如:

  Though it was cold, yet he went out without a coat.

  虽然很冷,但他没穿外衣就出去了。
