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。
3)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。
4)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。
5)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。
6)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。
