一.条件状语从句
引导条件状语从句的连接词有：If，unless, as long as, in case, provided that, on condition that, if only(要是…多好), only if只要). supposing/ suppose(假设)
1. If 如果
If you don’t hurry up, you will miss the plane.
If it snows tomorrow, the flight will be canceled.
注：从句的动作发成在将来时,则主句将来时,从句用一般现在时表将来。
2. Unless …如果不，除非=if not
We can’t get there on time unless we book the earliest flight
We cannot get there on time if we don’t book the earliest flight.
He will not join us unless he changes his mind.
3. As long as “只要”
We will succeed as long as we keep on trying.
A man is not old as long as he is seeking something.
4. As (so) far as … “据…所知…"
As far as I know, he speaks English very well.
5. In case ”假使，如果万一”
The plane cannot take off in case it rains.
Send us a message in case you have any difficulty.
6. Provided that “如果”有时省略that, 常翻译成“如果“
The plane will be in good condition provided that it is taken care of carefully.
7. On condition that ”条件是…..”
He said that he would come to the meeting on condition that no one asked him to speak.
二.地点状语从句
地点状语从句只有两个连词：Where wherever
1. Where —“在......地方”
Put the medicine where you can easily get it.
Where there is o will, there is a way.
2. Wherever — 无论哪里
Wherever you ore. I will be right there waiting for you.
易错点：在地点状语从句之前，不要使用介词。
比如：你应该把书放在原来的地方。
(误)You should put the book at where it was.
(正)You should put the book where it was.
比如：我们应该到最需要我们的地方去。
(误)We should go to where we are needed most.
(正)We should go where we are needed most.
三.原因状语从句
原因状语引导词：because, as, since, now that, considering that, for, seeing that
这六个连词都用于表示原因，但在语气上一个比一个弱。
1.Because …因为，Because引导从句通常放在主句后
Mr. Smith was very upset because he couldn't find his luggage.
He said that he couldn't work because the computer was out of order.
2.Because和for的区别：
For是并列连词，只用于连接表示原因的分句，因此不能用于句首，because表示原因时，可位于句首。
(误)For he did not obey the rules, he was punished.
(正)Because he did not obey the rules, he was punished.
