1、 課題名稱 二輪復習—— 狀語從句 學習目標：狀語從句的各種類型，并正確使用從屬連詞 學習難點： 狀語從句中的時態(tài)表達法 在復合句中修飾主句中的動詞、形容詞和副詞的從句叫狀語從句。 狀語從句根據(jù)它表達的意思不同可分為時間狀語從句、地點狀語從句、條件狀語從句、比較狀語從句、目的狀語從句、結果狀語從句、方式狀語從句、讓步狀語從句和原因狀語從句等。狀語從句如果放在主句前通常用逗號分開。 一、復習時需注意的要點 1、如果hardly, scarcely 或no sooner等置于句首，句子必須用倒裝結構： 例如：Hardly /

2、 Scarcely had I got home when it began to rain. No sooner had I got home than it began to rain. 2、Not until …在句首，主句用倒裝。 例如：Not until the early years of the 19th century did man know what heat is. 直到19 世紀初，人類才知道熱能是什么。 Not until I began to work did I realize how much time I had wasted. 直到我開始工作，我

3、才認識到了我已蹉跎了幾多歲月。 3、當從句的動作發(fā)生于主句動作之前，只能用when 引導這個從句，不可用as 或 while。 例如：When you have finished your work, you may have a rest. 4、如從句表示"隨時間推移"，連詞能用as，不用when 或while。 例如：As the day went on, the weather got worse.　 日子一天天過去，天氣越變越壞。 5、as, though 引導的倒裝句 as / though引導的讓步從句必須把表語或狀語提前（形容詞、副詞、分詞、實義動詞提前）。句首名詞

4、不能帶任何冠詞。 如句首是實義動詞，助動詞放在主語后。如果實義動詞有賓語和狀語，隨實義動詞一起放在主語之前。 例如：Child as /though he was, he knew what was the right thing to do. = Though he was a small child, he knew what was the right thing to do. Try hard as he will, he never seems able to do the work satisfactorily. = Though he tries hard, he ne

5、ver seems… 雖然他盡了努力，但他的工作總做的不盡人意。 二、歷屆高考試題分析 例1、Generally speaking, _________ according to directions, the drug has no sid-effect. A. when taking B. when taken C. when to take D. when to be taken 答案為B。 【解析】 這是一個由when引導的時間狀語從句，原句應為“Generally speaking ,when it is taken accordin

6、g…”。由于take用被動時，主從句主語一致，因此從句中的it was可以被省略，簡化為when taken…分詞短語作狀語，而選A、C時則缺乏主語。譯文：通常地說，當這藥按照指導說明被服用的話是沒有副作用的。 例2、—Dad, I've finished my assignment. —Good ,and _________ you play or watch TV ,you mustn't disturb me. A. whenever B. whether C. whatever D. no matter 答案為B。 【解析】 no mat

7、ter不能直接引導讓步狀語從句，應用no matter + wh族疑問詞方可，故排除D；盡管A、C都有“無論”的意思，但只有B項whether可與or連用，表示選擇，即“無論你玩還是看電視，不許打擾我”。 例3、The famous scientist grew up _______ he was born and in 1930 he came to Shanghai. A. when B. whenever C. where D. wherever 答案為C。 【解析】 where引導的是地點狀語從句。譯文：這位著名的科學家在他的出生地長大，1930

8、年他來到上海。因為在從句中有表示時間的介詞短語in 1930,所以可以排除when和whenever; wherever引導讓步狀語，意思是“無論在哪里”，與句意不符。 例4、________, I have never seen anyone who's as capable as John. A. As long as I have traveled B. Now that I have traveled so much C. Much as I have traveled D. As I have traveled so much 答案為C。 【解析】

9、 這是一個讓步狀語從句。as在引導讓步狀語從句時，要把形容詞或副詞放在它的前面。如果是名詞，一般不加冠詞。如：Child as he is, he has learned two thousand new words .As long as“只要……”引導條件狀語從句；Now that“既然”引導原因狀語從句；As“因為”引導原因狀語從句。譯文：雖然我走過了那么多地方，我從來沒有見過像約翰這樣有能力的人。 例5、In such dry weather, the flowers will have to be watered if they________. A. have surviv

10、ed B. are to survive C. would survive D. will survive 答案為B。 【解析】 這是一個條件狀語從句，主句用了一般將來時態(tài)。在條件狀語從句中，一般不能使用將來時，但能和be to do的形式連用，所以應填are to survive。譯文：在如此干旱的天氣里，如果你想要花成活，就得給它們澆水。 例6、The WTO cannot live up to its name _____ it does not include a country that is home to one fifth of mankind.

11、A．a(chǎn)s long as B．while C．if D．even though 答案選C。 【解析】 從句子意思可知，是一個條件狀語從句。as long as“只要……”引導條件狀語從句經(jīng)常用肯定句，所以要填if。譯文：如果WTO不包括一個占人類五分之一的國家，它就名不符實了。 例7、She found her calculator ________ she lost it. A. where B. when C. in which D. that 答案為A。 【解析】 這是一個

12、地點狀語從句，意思是“東西是在丟的地方找到的?！眎n which用于定語從句中，其前必須有先行詞。這個句子中沒有先行詞，所以不能填in which。 例8、—I'm going to the post office. — ________you're there, can you get me some stamps? A. As B. While C. Because D. If 答案為B。 【解析】 while引導時間狀語從句，意思是“當……時”。這句話的意思是“當你在那兒的時候，是否能給我買一些郵票？”as雖然也可以引導時間狀語從句，但其意思是“一邊……一

13、邊……”；because引導的是原因狀語從句；if引導的是條件狀語從句，對方已經(jīng)說明要到郵局去，不能再作假設。 例9、You should make it a rule to leave things ________you can find them again. A. when B. where C. then D. there 答案為B。 【解析】 where引導地點狀語從句。這句話的意思是“你應該作出一個規(guī)矩，把東西放在你能再找到它們的地方?！? 例10、We'll have to finish the job, _______

14、_. A. long it takes however B. it takes however long C. long however it takes D. however long it takes 答案選D。 【解析】 however引導讓步狀語從句。要用陳述句的語序。 三、鞏固練習 Direction: Beneath each of the following sentences there are four choices marked A, B, C and D. Choose the best answ
