狀語從句（2）

1、語法·剖析·活用狀語從句在上一個模塊中我們學習了用不同的引導詞引導時間狀語從句，在本模塊中，我們介紹其他幾種狀語從句的具體應用。看下表所示：名稱引導詞例句原因狀語從句BecauseShe didnt go to school today because she was ill.目的狀語從句so thatShe dressed like a man so that she could join the army.結果狀語從句SoHe got up too late so he missed the school bus.注意：目的狀語從句中的時態(tài)表示未來，可能性；而結果狀語從

2、句中表示已經發(fā)生。1.引導原因狀語從句的連詞原因狀語從句一般由because, since, as, for引導，注意as, because, since和for的區(qū)別:1)如果原因是構成句子的最主要部分,一般用because。because引導的從句一般不放在句子的開頭。如:I missed the train because I got up late.注:對于以why開頭的問句,一般只能用because引導的從句回答。2)如果原因已為人們所知,或不如句子的其余部分重要,就用as或since，since比as稍微正式一些。as和since引導的從句一般放在句子的開頭。如:As he was

3、 not well, I decided to go there without him.Since this method doesnt work, lets try another.3)for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:I decided to stop and have lunch, for I was feeling quite hungry.2.引導結果狀語從句的連詞除so之外，還有so/such.that.,so that等。1) so.that結構在某種情況下可以與enough to和too.to結構相互轉換。如:She is so s

8、sD. when the meeting would start思路解析：本題考查賓語從句。賓語從句的從句要用陳述語序，Could you.?表達委婉的語氣，而不是過去時，根據(jù)答語可以知道引導詞要用when，所以本題選擇A項。答案：A黑色陷阱：本題容易錯選D項，因為沒有注意到句中could 不是表達過去時。綠色通道：在含有賓語從句的復合句中，不管主句用什么語序，從句必須用陳述語序，時態(tài)取決于主句的謂語時態(tài)，即主句是一般現(xiàn)在時，從句根據(jù)實際情況選用不同的時態(tài)，主句是一般過去時，從句要用相應的過去時態(tài)。但應注意Could/Would you.?表達委婉的語氣，不是過去時。例2(2010江蘇蘇州中考

9、) What will you do if it _tomorrow?Ill stay at home and watch the match on TV.A. rain B. rainsC. will rain D. is raining思路解析：本題考查if 引導的條件狀語從句。主句用一般將來時，從句用一般現(xiàn)在時。所以本題選擇B項。答案：B黑色陷阱：本題容易錯選C項。因為有的同學只注意tomorrow 應該用將來時，而忽略了if 從句。綠色通道：本題的關鍵是if 引導的條件狀語從句。主句用一般將來時，從句用一般現(xiàn)在時。類似的還有as soon as, before, when, until

10、 等引導的從句。例3(2010江蘇南京中考) Well try our best to do the work with_ money and _people.A. little; fewB. a few; a littleC. less; fewerD. fewer; less思路解析：本題考查less 和fewer 的用法。less后接不可數(shù)名詞，fewer后接可數(shù)名詞。所以本題選擇C項。答案：C黑色陷阱：本題容易錯選A項。許多同學不能正確理解句子的意思，將此題錯誤地用了原級。綠色通道：money為不可數(shù)名詞，只能用little, a little 或less修飾；people 為可數(shù)名詞

11、的復數(shù)，應用a few, few 或fewer修飾。例4(2010黑龍江哈爾濱中考) The boy was able to _himself when he was very young.A. dressB. wearC. put onD. have on思路解析：本題考查詞組dress oneself,意思是“自己穿衣服”。所以本題選A項。答案：A黑色陷阱：本題容易錯選C項，因為沒有搞清楚put on 后接表衣服的名詞，而不是接人。綠色通道：做本題的關鍵是掌握dress的用法，以及和wear, put on的區(qū)別。dress, put on,意思是“穿上”，表示動作；dress 之后通常接

12、人，不接衣服；put on后跟表衣服的名詞；wear 意思是“穿著”，表示狀態(tài)。例5(2010江蘇徐州中考) Dont make me _ this or that. Im too busy!A. to doB. doC. doingD. done思路解析：本題考查make sb. do的結構，所以本題選B項。答案：B黑色陷阱：本題容易錯選A項，因為有的同學認為make sb.后接動詞不定式作賓語補足語。綠色通道：make sb. do 動詞不定式作賓語補足語，應省略to,類似的詞還有l(wèi)et，have 等。原創(chuàng)題看圖表，用more, less或fewer完成練習。NowIn 100 years
