e.g. I did not go to bed until I finished my homework. 直到我完成了作业才去睡觉。

if
(1)“如果”,从句常用一般现在时来表示将来。

unless
(2)“除非”,注意为了强调动作的完成,从句中也能用完成时。
e.g. We will go for a picnic tomorrow unless it rains. 除非天下雨,我们会去野餐。(unless it rains = if it doesn't rain ).
as long as
(3)“只要...”,从句常用一般现在时来表示将来。

原因状语从句
because
(1)“因为”,表示因果关系的语气最强,常用来回答why的提问。
e.g. I was late for school because I got up late. 因为我起晚了,所以我上学迟到了。
【注意】because“因为”,so“所以”,用于并列句时,两者不能用时出现在一个句子里,只能用一个。
e.g. Because he was tired, he couldn't walk here. = He was tired, so he couldn't walk here. 因为他累了,所以没能走到那。
since
(2)“既然”,常放在句首。
e.g. Since Monday is Bob's birthday, let's give him a party. 既然周一是鲍勃的生日,让我们给他举办一个派对了。
目的状语从句
so that
(1)“为了,以便”,表示目的。
e.g. I’ll speak slowly so that you can understand me. 为了你能懂我,我会慢慢说。
in order that
(2)“为了”,当从句主语和主句主语一致时,可以用in order that引导。
e.g. He worked day and night in order that he could succeed.(=in order to succeed.) 为了成功,他夜以继日地工作。
结果状语从句
so..that.../ such...that...
由“如此...以至于...”引导, so后接形容词或副词;such后接名词。
e.g. She is so lovely that we like her very much. 她太可爱了,我们都很喜欢她。
e.g. She is such a lovely girl that we like her very much. 她是如此一个可爱的女孩儿,我们都很喜欢她。
特别注意:
当名词是复数或不可数名词时,只能用such。
让步状语从句
though\although
(1)“虽然,尽管”,都表示让步,一般情况下可以互换,although大多放在句首,不可和but连用。
e.g. Although he was Japanese, he spent most of his life in China. 虽然他是一个日本人,但在中国度过了大半生。
even though\even if
(2)“即使,尽管,纵然”,都表示让步,语气比though\although更强。
e.g. Even though he is 24 now, he is still like a little child. 尽管他现在24岁了,但他仍像一个小孩儿。
wh-ever
(3)类引导让步状语从句。引导让步状语从句时,常可以换成“no matter +相应的wh-词语”,在引导名词性从句时只能用wh-ever.
e.g. Whenever I am unhappy, it is my friend who cheers me up.
=No matter when I'm unhappy, it is my friend who cheers me up. 无论何时我不高兴,都是我的朋友使我振作起来。
