原因、結(jié)果、目的狀語從句講解和練習(xí)(答案)

1、學(xué)習(xí)必備歡迎下載原因狀語從句(1) 原因狀語從句通常由because, since, as,for引導(dǎo)。(2)because表示直接原因，語氣最強(qiáng)。because引導(dǎo)的原因狀語從句多放在主句之后?；卮鹩蓋hy提出的問題，只能用because。此外， because和 so 不能 同用在一個句子里。例如：- Why arent going there? - Because I don t want to.since引導(dǎo)原因狀語從句，相當(dāng)于now that，意思是 “因?yàn)?，既然?鑒于 ”。例如：Since the rain has stopped， lets go for a walk. 既然雨

2、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(dǎo)的原因狀語從居多放在句首。例如： As he has no car, he cant get there easily.Since we have no money, we can t buy it.(4)for 表示所說的理由是一種補(bǔ)充說明,for 引導(dǎo)的從句一般不放在句子的開頭。如I decided to stop and have lunch, for I was feeling quite hungry.:小試牛刀：I was late for class yesterday _ there

3、 was something wrong with my bike.He took off his coat _ he felt hot.you can t answer the question, I ll ask someone else.結(jié)果狀語從句(1) 結(jié)果狀語從句由sothat, suchthat, so that 引導(dǎo)。(2) sothat 語 such.that可以互換。在由so.that引導(dǎo)的結(jié)果狀語從句中，so是副詞，與形容詞連用。其結(jié)構(gòu)是 :.“so +形容詞（副詞）+ that +從句 ”。例如：He was so glad that he couldnt say a

4、word.Mother lives so far away that we hardly ever（幾乎不，從來不）see her.在由suchthat引導(dǎo)的結(jié)果狀語從句中，such是形容詞，它修飾的可以是單數(shù)或復(fù)數(shù)可數(shù)名詞，也可以是不可數(shù)名詞；其結(jié)構(gòu)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(jié)構(gòu)是

5、可以互換的。例如： It was such a wonderful film that all of us wanted to see it again.=The film was so wonderful that all of us wanted to see it again.(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 roses.He ha s so little time that he can

6、 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too.to. 句型轉(zhuǎn)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

7、了，可以去上學(xué)。小試牛刀： It is _ hot in the room _ we have to go out for a walk.There wereIt was a wonderful movie all of us wanted to see it again.little water in the bottlethe bird couldn t reach it.學(xué)習(xí)必備歡迎下載He is so young that he couldntgo to school.=.The classroom is so big that it can hold 100 person. =.目的

8、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(dǎo)。例如： We started early so that we could catch the first train.We used the computer in order that we might save time.(2)so that可引導(dǎo)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 early（in order

9、） to get to school on time.(3)so that既可引導(dǎo)目的狀語從句，又可引導(dǎo)結(jié)果狀語從句。區(qū)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(tài)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(jié)果狀語從句)小試牛刀：I hurriedI wouldn't be late for class.We
