is OK as it was in the miss each other when they are I take exams, my mind blanks and more college students, prefer to stay in 、初中狀語從句重點：時間、條件狀語從句。（一）時間狀語從句中的連接詞：When / while / asafter / before / sinceAs soon astill（不可用于句首）/ until By the time（解釋以上連接詞的意思）（二）時間狀語從句中的時態(tài)： begin to know something when you think you know president laughed as he the end of this year, it will be four months since they joined the went home after we had finished the father had left for Canada before the letter ：主句從句現(xiàn)在時現(xiàn)在時/過去時將來時現(xiàn)在時/過去時過去時過去時提問：為什么有些動作會用進行時/完成時表示？ 觀察下列句子中的動詞：While my mom was reading the newspaper, I was watching my mom came in, I was watching mom was reading the newspaper while I came left the office after he(had)finished the writer had written many unknown books before he got famous overnight.（三）條件狀語從句的連接詞和時態(tài)：Unlessif時態(tài)一致性：主句從句將來時現(xiàn)在時（過去將來時過去時）翻譯下列句子：。If you ask him, he will help ，比賽將照常進行。The game will be held unless it I were you, I would not be so ，我不會那么笨的。練習(xí)：____ the days went on, the weather got Tom ____ into the house when no one 。was slipped。looked 。had slipping。lookedHe was told that it would be at least three more months he can he can he could he could recover They ____ the train _____ it disappeared in the , , , , until It’s years ____ I met an old If you _____(open up)your mind, you ______(find)the world is full of stars are shining in the was no air pollution.(用when連接兩個句子)We _____(leave)school before we _____(finish)the homework..我們完成作業(yè)前就回家了。第四篇：狀語從句講解+練習(xí)(導(dǎo)學(xué)案)狀語從句學(xué)習(xí)目標：、記憶，記住狀語從句的考點、講解，會用狀語從句的知識解決問題。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when, as, while, whenever, after, before, till(until), since, once, as soon as(或the moment), by the time, no sooner … than, hardly(scarcely)… when, every time等引導(dǎo)。 I came into the office, the teachers were having a started as soon as he received the you see him, you will never forget sooner had I gone to bed than I went to sleep.（二）原因狀語從句原因狀語從句是表示原因或理由的，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。 is disappointed because he didn39。t get the it is raining, I will not go that you mention 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。 wherever you a mark where you have a question.（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。 clearly, so that they may understand has bought the book in order that she could follow the TV left early in case he should miss the train.（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)。 was ill, so that she didn’t attend the was so excited that he could not say a is such a good teacher that everyone 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, unless, so(as)long as, on condition that, so(as)far as, if only(= if)。注意：條件從句中的if 不能用whether替換。 he is not in the office, he must be out for may borrow the book so long as you keep it far as I know（據(jù)我所知）, he will be away for three can go swimming on condition that(= if)you don’t go too far away from the river he had e a few minutes earlier, he could have seen her.（七）讓步狀語從句讓步狀語從句可由although, though, as, even if(though), however, whatever, whether … or, 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的。 he is a child, he knows a as he is, he knows a (= No matter what)you say, I’ll never change 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)。 must do the exercise as I show acted as if nothing had happened.（九）比較狀語從句比較狀語從句常用than, so(as)… as, the more … the more等引導(dǎo)。 have made a lot more mistakes than you smokes cigarettes as expensive as he can busier he is, the happier he feels.（十）使用狀語從句時要注意的幾個問題在時間和條件（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?！痩l go outing if it doesn’t rain ’ll write to you as soon as I get to 、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。(he was)still a boy of ten, he had to work day and (you are)asked you may e (it is)necessary I’ll explain to you 、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，能引導(dǎo)多種從句。 are to find it where you left it.（地點狀語從句）Tell me the address where
