2) 地点状从：
① Where there is a will, there is a way.
在有意志力的地方，就有一条路。=有志者，事竟成。
② Wherever there is smoke, there is a fire.
在任何有有烟的地方，一定有一堆火。=无风不起浪。
写作技巧：在写作中，我们可以化用套用句式而不是简单的引用原句。比如在一场地震中，一方有难八方支援，人间有真情人间有大爱。我们可以说：
Where there is love, there is hope.哪里有爱，哪里就有希望。
3) 原因状从
① —Why are you late? —Because I missed the early bus.
—你为什么迟到？ —因为我没赶上早班车。
② Since/Now that everyone is here, let's begin.
既然大家都来了（大家都知道的事实，显而易见的原因），让我们开始吧。
注：表因为的短语，to和of介词后加名词不能连接句子。
3to： thanks to, owning to, due to
3of: because of, as a result of, on account of.
4) 结果状从
① I took an umbrella, so that I didn't get wet in the rain.
我带了把伞，因此我没淋到雨。
② 雨下得如此大以至于（导致……结果）我们不能出去。
It is so heavy a rain that we can't go out.
It is such a heavy rain that we can't go out.
It is raining so heavily that we can't go out.
注：so是副词，可修饰形容词/副词，such是形容词，可修饰名词/名词词组。so/such和that之间有名词时：
① 可数名词复数和不可数名词，只用such
② 可数名词单数，so，such都可以语序不同
③ 名词前有表数量多少的形容词时，只用so
口诀：名前such,形副so,多多少少也用so，little属特殊，“小”用such,“少”用so。
例句：They are such little children that they can't do anything.
他们是如此小的孩子以至于他们什么也做不了。
He earns so little money that he can't support his family.
他赚钱如此少以至于不能养家。
5) 目的状从
① Take an umbrella in case it rains.
带把伞,以防下雨。（以防：为了防止）
② I take an umbrella so that(=in order that) I won't get wet in the rain. 为了不被雨淋湿，我打了把伞。（主将从现）
注意跟前句对比：I took an umbrella, so that I didn't get wet in the rain.我带了把伞，因此我没淋到雨。（主过从过）
6) 方式状语从句
① Do the homework as the teacher told you.
按照老师告诉你的（方式）去做作业。
② He talks as if he were the chairman.
他说起话来（的方式）就像自己是主席一样。
7) 比较状语从句
①He forgets faster than he learns.
他忘的比学的快。
②He forgets as fast as he learns.
他忘的跟学的一样快。（先有比较才知道一样）
8) 条件状语从句
① If you promise to return on time, I will lend you my car.
如果你许诺按时归还，我可以借给你我的车。
注意：unless=if not

=I won't lend you my car if you don't promise to return on time.
我不会借给你我的车如果你不许诺按时归还。
② I will lend you my car on condition that you promise to return on time.
我可以借给你我的车条件是你许诺按时归还。
③ I will lend you my car on as long as you promise to return on time.
只要你许诺按时归还，我可以借给你我的车
9) 让步状语从句
① 尽管他岁数大了，他坚持学习。
Although/Though/While/Even though(if) he is old, he keeps learning.
Old as（though） he is, he keeps learning.
注意：as必须倒装，though可倒可不倒，although等不能倒装。
② Whichever way you choose, wherever you go, whatever you do, whoever you love, however you hate me, whenever you come back, I will wait for you here.
无论你选择那一条路，无论你去向何方，无论你做了什么，无论你爱上谁，无论你多讨厌我，无论你何时归来，我都将在这等着你。
