狀語從句總結(jié)及例題

1、狀語從句總結(jié)及例題由從句擔(dān)任的狀語，在句子中可修飾謂語（或其它 動詞）、形容詞、 副詞或是整個句子，它可以用來表示時間、地點、原因、目的、結(jié)果、條 件、方式、比較、讓步等。 狀語從句是一較大的語法項目，也是近幾年高 考題中常見的一個重要試點。高考中已考查了時間、讓步、地點、條件、 目的等狀語從句，這些從句仍是今后高考熱點，應(yīng)作充分準備。同時對方 式狀語從句也應(yīng)引起重視。(一) 時間狀語從句表示時間的狀語從句可由 whe n, as, while, whe never, after, before, till (until), since, once, as soon as (或 the mom

2、ent), bythe time, no soon er than, hardly (scarcely) when, everytime等引導(dǎo)。e.g. When I came into the office, the teachers were having a meeti ng.He started as soon as he received the n ews.Once you see him, you will n ever forget him.No sooner had I gone to bed tha n I went to sleep.（二）原因狀語從句原因狀語從句是表示原

3、因或理由的，引導(dǎo)這類從句的最常用的 連詞是 because, since, as , now that （既然）等，for表示因果關(guān)系時（它引 導(dǎo)的不是從句）為并列連詞，語氣不如 because強。e.g. He is disappo in ted because he did nt get the positi on.As it is raining, I will not go out.Now that you men ti on it, I do remember.(三) 地點狀語從句引導(dǎo)地點狀語從句的連詞是 where 和wherever等。e.g. Sit wherever you

4、like.Make a mark where you have a questi on.（四）目的狀語從句引導(dǎo)目的狀語從句最常用的詞（組）是 so, so that（從句謂語常有 情態(tài)動詞），in order that, in case（以防，以免）等。e.g. Speak clearly, so that they may un dersta nd you.She has bought the book in order that she could follow the TV less ons.He left early in case he should miss the train.（

5、五）結(jié)果狀語從句結(jié)果狀語從句是表示事態(tài)結(jié)果的從句， 通常主句是原因，從句是結(jié)果。 由so that （從句謂語一般沒有情態(tài)動詞）,so that, such that 等引導(dǎo)。e.g. She was ill, so that she did nt atte nd the meeti ng.He was so excited that he could not say a word.She is such a good teacher that every one admires her.（六）條件狀語從句條件狀語從句分真實性（有可能實現(xiàn)的事情）與非真實性（條件與事 實相反或者在說話者看來不大

6、可能實現(xiàn)的事情）條件句。引導(dǎo)條件狀語從 句的詞（組）主要有 if, uni ess, so （as） long as, on con diti on that, so （as） far as, if only （ = if ）。注意：條件從句中的if不能用 whether替換。e.g. If he is not in the office, he must be out for lun ch.You may borrow the book so long as you keep it clea n.So far as I know（據(jù)我所知），he will be away for three

7、 mon ths.You can go swimming on condition that （ = if ） you dont go too far away from the river bank.If he had come a few minu tes earlier, he could have see n her.（七）讓步狀語從句讓步狀語從句可由 although, though, as, even if (though),however, whatever, whetheror, no matter who (when,what,）等引導(dǎo)。注意：as引導(dǎo)的讓步狀語從句一般是倒裝

8、的。e.g. Though he is a child, he knows a lot.Child as he is, he knows a lot.Whatever ( = No matter what ) you say, Ill n ever cha nge my mind.(八) 方式狀語從句方式狀語從句常由 as, as if (though), the way, rather than等引導(dǎo)。e.g. You must do the exercise as I show you.He acted as if nothing had happe ned.(九) 比較狀語從句比較狀語從

9、句常用 than, so (as) as, the more the more 等 引導(dǎo)。e.g. I have made a lot more mistakes tha n you have.He smokes cigarettes as expe nsive as he can afford.The busier he is, the happier he feels.(十)使用狀語從句時要注意的幾個問題1、 在時間和條件(有時也在方式、讓步等)從句中，主句是一般將來 時，從句通常用一般現(xiàn)在時表示將來。e.g. Well go outi ng if it does nt rain tomo

10、rrow.ril write to you as soon as I get to Sha nghai.2、有些時間、地點、條件、方式或讓步從句，如果從句的主語與主句主語一致(或雖不一致，是it)，從句的謂語又包含動詞 be，就可省略 從句中的主語+ be”部分。e.g.When (he was) still a boy of ten, he had to work day andn ight.If (you are) asked you may come in.If (it is) necessary Ill explain to you again.3、注意區(qū)分不同從句：引導(dǎo)的是什么從句，不僅要根據(jù)連詞，還要根據(jù)句子結(jié)構(gòu)和句意來判別。以where為例,e.g. You are to find it where you left it.能引導(dǎo)多種從句。（地點狀語從句）Tell
