原因、結(jié)果、目的狀語從句講解和練習(xí)和答案

1、狀語從句總結(jié)、原因狀語從句(1)原因狀語從句通常由because, si nee, 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。回答由 why提出的問題，只能用because。此外，because和so不能同用在一個(gè)句子里。例如： Why aren t going there? Because I don t want to.since弓I導(dǎo)原因狀語從句，相當(dāng)于 now that，意思是因?yàn)?，既? 鑒于”。例如：Si nee the rain has stopped, let s go for a walk.既然雨停了，我

2、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。例女口 : As he has no car, he can t get there easily.Since we have no money, we can t buy it.(3)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。如練習(xí)：I decided to stop and have lun ch, for I was feeli ng quite hun gry.I was late for class yesterdaythere was s

4、other 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 n obody wan ted to do anything.He had such long arms that he could almost touch the ceili ng.（天花板）有時(shí)上述兩種結(jié)構(gòu)是可以互換的

5、。例如：It was such a won derful film that all of us wan ted to see it aga in.=The film was so won derful that all of us wan ted to see it aga in.例如： Soon there were so many deer that they ate up all the wild roses.He has so little time that he can t go to the cinema with you.如果主從句的主語相同，并且從句是否定的形式，可以用to

6、o.to句型轉(zhuǎn)化。例如： He was so excited that he could nt 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 eno ugh to go to school.他夠大了，可以去上學(xué)。練習(xí)：It ishot in the roomwehave to go out for a walk.It wasa

7、 won derful movieall of us wan ted to see it aga in.Therewerelittlewater in the bottlethe bird couldn t reachit.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(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(shí)

8、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 ） 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(gè)：1）目的狀語從句里往往帶有情態(tài)動(dòng)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 y

9、ou.（目的狀語從句）Jack is badly ill so that he has to rest. （結(jié)果狀語從句）練習(xí)：I hurried I wouldnt be late for class.We should go by buswe can get there earlier.May I sit n earerI can see more clearly?（4）補(bǔ)充：f so as to （肯定結(jié)構(gòu) ）eg.
