2) 地点状从：
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。
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
—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。
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
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。
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：
可数名词复数和不可数名词，只用such
可数名词单数，so，such都可以语序不同
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

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

9) 让步状语从句

注意：as必须倒装，though可倒可不倒，although等不能倒装。
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。
