地點狀語從句
地點狀語從句通常由where, wherever 引導。
Where I live there are plenty of trees.
我住的地方樹很多。
Wherever I am I will be thinking of you.
不管我在哪裏我都會想到你。
原因狀語從句
比較：because, since, as和for
1) because語勢最強，用來說明人所不知的原因，回答why提出的問題。當原因是顯而易見的或已爲人們所知，就用as或 since。
I didn't go, because I was afraid.
Since /As the weather is so bad, we have to delay our journey.
2) 由because引導的`從句如果放在句末，且前面有逗 號，則可以用for來代替。但如果不是說明直接原因，而是多種情況加以推斷，就只能用for。
He is absent today, because / for he is ill.
He must be ill, for he is absent today.
目的狀語從句
表示目的狀語的從句可以由that, so that, in order that, lest, for fear that, in case等詞引導，例如：
You must speak louder so that /in order that you can be heard by all.
He wrote the name down for fear that(lest) he should forget it.
Better take more clothes in case the weather is cold.
結果狀語從句
結果狀語從句常由so… that 或 such…that引導，掌握這兩個句型，首先要了解so 和 such與其後的詞的搭配規律。
比較：so和 such
其規律由so與such的不同詞性決定。such 是形容詞，修飾名詞或名詞詞組，so 是副詞，只能修飾形容詞或副詞。 so 還可與表示數量的形容詞many, few, much, little連用，形成固定搭配。
so foolish such a fool
so nice a flower such a nice flower
so many / few flowers such nice flowers
so much / little money such rapid progress
so many people such a lot of people
( so many 已成固定搭配，a lot of 雖相當於 many，但 a lot of 爲名詞性的，只能用such搭配。)
so…that與such…that之間的轉換既爲 so與such之間的轉換。
The boy is so young that he can't go to school.
He is such a young boy that he can't go to school
條件狀語從句
連接詞主要有 if, unless, as/so long as, on condition that 等。.
if 引導的條件句有真實條件句和非真實條件句兩種。非真實條件句已在虛擬語氣中闡述。
unless = if not.
Let's go out for a walk unless you are too tired.
If you are not too tied, let's go out for a walk.
典型例題
You will be late ___ you leave immediately.
A. unless B. until C. if
D. or
答案A。 句意：除非你立即走，否則你就回遲到的。可轉化爲 If you dong leave immediately, you will be late. B、D句意不對，or錶轉折，句子如爲 You leave immediately or you will be late.
讓步狀語從句
though, although
注意： 當有though, although時，後面的從句不能有but，但是 though 和yet可連用
Although it's raining, they are still working in the field.
雖然在下雨，但他們仍在地裏幹活。
He is very old, but he still works very hard.
雖然他很老，但仍然努力地工作。
Though the sore be healed, yet a scar may remain.
傷口雖癒合，但傷疤留下了。 (諺語)
