考点1 状语从句的分类和考点
① 时间状语从句:
连接词有:before, after, until/till, as soon as, when, while, as, since
其中when、not..until....、as soon as要遵守“主将从现”原则。
I won’t come back until you call me. 直到你给我打电话我才会回来。
The flights will be allowed to resume flying when the sky turns clear.
I will go to sleep as soon as I come back home. 我一回到家我就会去睡觉。
Where have you been since I last saw you?
I as well as several colleagues have been in Beijing since 2010.
Mr. Green has made quite a few friends since three years ago.
辨析: when, while, as “当…时候”
过去进行时(主句) +when+ 一般过去时(从句)
过去进行时(主句)+while+过去进行时(从句)
when既可以指"时间点",与瞬间动词连用,也可以指"时间段",与延续性动词连用(=while)。
while表示时间段,因此,while引导的时间状语从句的谓语动词要用延续性动词。
while 表对比“然而”时,前后动词时态一致!
常用搭配:as time goes by/on随着时间的过去
★since的重要句式:It is +一段时间+ since+ 从句 (一般过去时)
It is four years since my sister lived in Beijing.
② 原因状语从句
连接词:
1)Because用的最多,可以回答why的提问。
2)Since也很重要,但一般翻译成“既然”的意思
Since everybody is here, let’s have the party. 既然大家都到了,那我们就开始弄聚会吧。
3)as 也可以引导原因, 可以翻译为“由于”。
4)because不能与so连用。
Because it was raining, we stayed at home.
=It was raining, so we stayed at home.
--Why didn’t you go to school yesterday?
--Because I was ill.
Since everybody is here, let’s begin our meeting.
Since you can’t answer the question, I’ll ask someone else.
As you are in poor health, you should not stay up late.
because+ 从句; because of+ 名词/名词词性短语
He can’t come because he is ill.
He can’t come because of his illness.
③ 结果状语从句
1) so...that......如此。。。以至于。。。 so的后面基本都是跟的形容词或者副词
I am so hungry that I want to eat 10 hamburgers. 我是如此的饿以至于我想吃10个汉堡。
He ran so quickly that I couldn’t catch him. 他跑得是如此地快以至于我都赶不上他。
2) such ....that.........如此。。。以至于。。。 such后面基本跟的是名词性质的事物
He is such a clever boy that we all like him.
他是一个如此聪明的男孩以至于我们都喜欢他。
They are such kind teachers that the students feel happy.
他们是如此和善的老师以至于学生们都感觉开心。
如果名词前由many, much, little, few等词修饰时,只能用so, 不用such。
也就是:so + little/ many/much/ few +名词
Soon there were _____so____ many deer
