狀語從句總結

一、原因狀語從句

1原因狀語從句通常由becau; since; as; for引導..

2becau表示直接原因;語氣最強..becau引導的原因狀語從句多放在主句之后..

回答由why提出的問題;只能用becau..此外;becau和so不能同用在一個句子

里..

例如：------Why aren’t going there ------Becau I don’t want to.

since引導原因狀語從句;相當于now that;意思是“因為……;既然……; 鑒

于……”..

例如：Since the rain has stopped;let’s go for a walk. 既然雨停了;我們出

去散散步吧..

as和since語氣較弱;一般用來表示明顯的原因..由as和since引導的原因狀語

從居多放在句首..

例如 ：As he has no car; he can’t get there easily.

my bike.

He took off his coat _______ he felt hot.

you can’t answer the question; I’ll ask someone el.

二、結果狀語從句

1結果狀語從句由so…that; such…that; so that引導..

2so…that語hat可以互換..在由so...that引導的結果狀語從句中;so是副

詞;與形容詞連用..其結構是: “...so + 形容詞副詞+ that + 從句”..

例如： He was so glad that he couldn’t say a word.

Mother lives so far away that we hardly ever幾乎不;從來不 e her.

在由such…that引導的結果狀語從句中;such是形容詞;它修飾的可以是單數或復

數可數名詞;也可以是不可數名詞；其結構是: “...such +a / an + 形容詞+名詞

+ that + 從句”..

例如： It was such a hot day that nobody wanted to do anything.

He had such long arms that he could almost touch the ceiling.天花

板

有時上述兩種結構是可以互換的..

例如： It was such a wonderful film that all of us wanted to e it again.

=The film was so wonderful that all of us wanted to e it again.

Since we have no money; we can’t buy it.

I decided to stop and have lunch; for I was feeling quite hungry.

3for表示所說的理由是一種補充說明;for引導的從句一般不放在句子的開頭..如:

練習： I was late for class yesterday _______ there was something wrong with

3如果名詞前由many; much; little; few等詞修飾時;只能用so; 不用such..

例如：Soon there were so many deer that they ate up all the wild ros.

He has so little time that he can’t go to the cinema with you.

4如果主從句的主語相同;并且從句是否定的形式;可以用句型轉化..

例如：He was so excited that he couldn't go to sleep that night. = He was

too excited to go to sleep.

5如果主從句的主語相同;但從句是肯定的形式;可以用adj.+ enough替換..

例如：He is so old that he could go to school. = He is old enough to go to

school.

他夠大了;可以去上學..

練習： It is ___ hot in the room ___ we have to go out for a walk.

It was a wonderful movie all of us wanted to e it

again.

There were little water in the bottle the bird

couldn’t reach it.

三、目的狀語從句

1目的狀語從句通常由 so that; in order that為了;以便引導..

例如：We started early so that we could catch the first train.

We ud the computer in order that we might save time.

2so that可引導目的狀語從句;此時可用to或in order to替換;將其改為簡單句..

例如：He got up early so that he could get to school on time.

=He got up earlyin order to get to school on time.

3so that既可引導目的狀語從句;又可引導結果狀語從句..區別這兩種從句的辦法有

兩個：1目的狀語從句里往往帶有情態動詞can; could; may; might等..2從意

思上看;目的狀語從句往往表示的目的很明確..

例如： Speak clearly so that they may understand you. 目的狀語從句

Jack is badly ill so that he has to rest. 結果狀語從句

練習： I hurried I wouldn't be late for class.

We should go by bus ___ we can get there earlier.

May I sit nearer I can e more clearly

4 補充：

so as to…肯定結構 eg. He got up early so as to catch the early train.

so as not to…否定結構 eg. He got up early so as not to miss the early

train.

to… eg. He got up early to catch the early train.

in order that … eg. He got up early in order that he could catch

the early train.
