用一個句子作狀語,這個句子就是狀語從句。狀語從句通常用來修飾句子、動詞或形容詞,表示時間、地點、條件、原因、目的、結果、方式、比較等。引導狀語從句的連詞叫從屬連詞。
在句中表示結果的狀語從句叫結果狀語從句。引導結果狀語從句的從屬連詞主要有so that,so ...that ...,such ...that ...等。
1.引導結果狀語從句的從屬連詞及用法
(1)so that引導結果狀語從句意為“以致;結果”。如:
We arrived early,so that we got good seats.我們到得很早,因此我們座位很好。
He studied hard so that he passed the exam.他學習用功,所以考試通過了。
(2)so ...that ...引導結果狀語從句意為“如此……以至于……”。如:
It was so hot that we wanted to go swimming.天氣太熱,我們想去游泳。
It was so dark that he couldn't see the faces of others.天是那樣黑,其他人的臉他都看不見了。
(3)such ...that ...引導結果狀語從句意為“如此……以至于……”。如:
They are such wonderful players that no one can beat them.他們都是出色的運動員,沒有人能戰(zhàn)勝他們。
She is such a good teacher that all the students like her.她是那么好的老師,每個學生都喜歡她。
注意:
so ...that和such ...that中的that有時(尤其在口語中)可省略。如:
I am so busy I have no time to write a letter.我很忙,連寫信的時間都沒有。
There was such a lot of rain (that)we couldn't go out.雨那么大,我們沒法出去。
2.結果狀語從句的位置
結果狀語從句總是位于主句的后面。如:
It was very cold so that the river froze.天氣寒冷,河水都結冰了。
Xiao Liu finished his work so well that the boss praised him in public.小劉工作完成得好,結果老板當眾表揚了他。
It is such a heavy box that nobody can move it away.這是一個很重的箱子,誰也搬不走。
3.so ...that與such ...that 的用法辨析
so ...that ...與such ...that ...都表示“如此……以至于……”,so后接形容詞或副詞,而such后接名詞。但有時“so+形容詞”后還可接一個名詞,且這個名詞總是帶不定冠詞的單數可數名詞,而不能是復數名詞或不可數名詞。如:
[正] He is so clever a child that we all like him.這小孩很聰明,我們都喜歡他。
[正] They are such clever children that we all like them.這些孩子很聰明,我們都很喜歡。
[誤] They are so clever children that we all like them.
注意:
①so ...that ...句型可與such ...that ...句型相互轉換。如:
It's such an interesting film that we all want to see it.這電影很有趣,我們都想看。
It's so interesting a film that we all want to see it.這電影很有趣,我們都想看。
②在much,many,little,few 這四個詞前總是用so而不用such。如:
He had so many falls that he was black and blue all over.他摔了許多跤,結果全身都是傷。
He earns so little money that he can hardly feed his family.他賺的錢很少,幾乎不能養(yǎng)家糊口。
③so ...that和such ...that有時引導的并不是結果狀語從句,應注意區(qū)分。如:
I'm so happy that you could visit us.我很高興你能來看望我們。(其中的so用于加強語氣,相當于very,that后引導的是賓語從句。)
It's such a great pleasure that you are here.你在這里,真是令人非常高興。(其中的that后引導的是主語從句,句首的it為形式主語。)
