1、第五講第五講狀語從句狀語從句第一課時知識過關課李仕才1在時間狀語或條件狀語從句中，通常用一般現(xiàn)在時代替一般將來時，用現(xiàn)在完成時代替將來完成時。2辨析：when，while，as引導時間狀語從句。while必須與延續(xù)性動詞連用，強調(diào)主句動作延續(xù)到從句所指的整個時間時，只能用while；表示“隨著”只能用as；表示有規(guī)律的“每當”時或主句動作與從句動作有先后時，只能用when。3辨析：because，since，as引導原因狀語從句。because語氣最強，表示直接的原因，是說話人認為對方不知道的原因，它引導的從句通常位于主句之后；在回答why時，或者在強調(diào)結構中，只能用because。since
2、和as是對大家已知的事實提供理由或背景，它們引導的從句多位于主句前，有時也位于主句后。4as引導讓步狀語從句時，從句中的狀語、表語或動詞必須置于句首；though引導讓步狀語從句時，這些成分可置于句首也可用正常語序；但although等其他詞引導的讓步狀語從句不能將這些成分前置。5表示“雖然”的連詞though/although不能與表示“但是”的連詞but連用；表示“原因”的because等連詞不可與表示結果的連詞so等同時使用。讀語篇，悟語法。反復朗讀下列短文，領悟畫線黑體部分。思考：有多少種狀語從句？下面的狀語從句各屬于哪一種？有哪些特殊的用法？My mother was cooking
3、 in the kitchen while1 I was doing my school assignments.As soon as2 I finished my homework, I went to get some water to drink. Then the doorbell rang. However, my sister unlocked the door before3 I could open it.We were surprised the moment4 we saw her because5 her clothes and face were terribly di
4、rty.She looked much poorer than6 we expected. Since7 we didnt know what had happened to her, we stood there and waited for my sisters story. We wouldnt leave unless8 my sister told us all about it.

5、 way to my uncles home in the countryside. She couldnt get out of the ditch.Although11 she cried for help, no one could hear her.

6、d where14 she was and waited until15 a boy student passed by and gave her a hand. The boy reached her a long rope and told her to climb with the rope.

7、t hurry. Thats true. We should mind our step so that20 we can ensure our safety.1用于對比兩件事，意思是“而”用while，不能用when/as代替。2as soon as引導時間狀語從句，表示“一就”。3before表示“還沒來得及就”。4名詞詞組如the moment/the second/the day/the first time/next time.等可以用來引導時間狀語從句。5引導表示原因的從句時用because，其引導的原因狀語從句一般放在主句之后，而如果只是名詞性短語表示原因，則用because o
8、f引導。6在表示比較時，用than來引導比較狀語從句，than也可以作介詞。7對大家已知的事實提供理由或背景時，常用since引導，意思是“既然”。其引導的從句多在主句之前。8引導條件狀語從句，unlessif.not，是“除非，如果不”之意。9after/before引導表示時間先后的狀語從句，根據(jù)實際表達需要選用其一。10when引導表示“當時”的時間狀語從句。11引導讓步狀語從句時，可以用although或though，主句可以與副詞still連用，但不能再與連詞but連用了，一個復合句只需一個連詞。當是as引導讓步狀語從句時，從句中的狀語、表語或動詞置于句首。12however引導讓步
9、狀語從句時，其后常接形容詞或副詞，用于修飾該形容詞或副詞，wherever，whenever也可以引導讓步狀語從句，在從句中作狀語，相當于no matter how/where/when；另外whatever，whoever，whichever也可以引導讓步狀語從句。13表示“隨著”時，只能用as引導。14引導地點狀語從句時，用where/wherever，表示“在的地方”。15固定用法“直到才”可以用兩種表達形式：“延續(xù)性動詞until句子”(用肯定形式)；“not短暫性動詞until句子”(用否定形式)。16引導方式狀語從句時，可以用as，意思是“按照，像那樣”。17so that引導結果
10、狀語從句，從句表示的通常是某件事的結果。18when引導表示“當時”的時間狀語從句時，如果主句的主語和從句的主語是一致的，可以省略when從句的主語和be動詞，用分詞來表示。19表示“即使，盡管”的even though/if引導讓步狀語從句。20so that除了引導結果狀語從句外，還可以引導目的狀語從句，常與情態(tài)動詞can/could等連用。.單句填空(用適當?shù)膹膶龠B詞填空)1_ hard you try, it is very difficult to lose weight without cutting down the amount you eat.2Did Jenny retur

19、“延續(xù)性動詞until句子”用肯定形式，而“not短暫性動詞until句子”則用否定形式。3unless根據(jù)句意“除非他取得滿意的成績，否則他是不會放棄的”可知。4as引導讓步狀語從句時，從句中的狀語、表語或動詞置于句首，意思是“盡管”。5because根據(jù)前面可知“盡管他沒有取得很大的進步，但是他毫不氣餒，因為他堅信只要堅持，總會成功”。6As根據(jù)句意“隨著時間的流逝”，只能用as。7before引導時間狀語從句，意思是“在之前”。8Since從下文“we had a very good time”可以推斷出，此從句是原因狀語從句，從句在主句之前，常用since，意思是“既然”。9where
20、動詞stood是不及物動詞，其后跟的是表示地點的狀語從句，意為“站在曾經(jīng)學習和玩耍的地方”。10wherever從下文“or whatever we would do”可知，前面是一樣的結構，從句缺狀語。11although/though從下文的“we still fought back the tears”可知前面是讓步狀語從句。12than從前面的“a little sadder”可知是比較狀語，用than。第二課時高考研究課狀語從句在語法填空中的考查點規(guī)律方法1正確理解語境；2根據(jù)語境暗含的邏輯關系，選用正確的連接詞。1Pahlsson screamed _ loudly that he

23、n/If語境意義：這位媽媽在很大程度上和人類一樣用前肢抱著嬰兒，如果嬰兒哭了/當嬰兒哭的時候，它會前后搖晃，并輕輕拍打來安慰嬰兒。根據(jù)語境可知所填之處引導條件狀語從句或時間狀語從句。if語境意義：如果你不介意，我想停下來喘口氣。根據(jù)語境可知所填之處引導條件狀語從句。狀語從句在短文改錯中的考查點1根據(jù)語境體現(xiàn)的上下文邏輯關系，判斷連詞是否正確；2兩個并列成分之間是否只有一個連詞。規(guī)律方法1My only mistake was that I dropped some on the floor after I was packing them up.(2015陜西卷)_2Though not ve
