【正文】 作“是否”解的if和whether在具體用法上差別較大，同學們不易掌握。以下再有這種例句，都為2002年中考題，只寫某地。ve passed the exam． 2．連詞whether或if：它們起連接作用，在從句中不作句子成分，作“是否”解，口語中多用if。1．連詞that：只起連接作用，在從句中不作句子成分，也無詞匯意義，在口語中或非正式文體中常被省略。學習賓語從句并不難，只要你能過好下面的三道關：第一關，選好連接詞（也有人叫關聯(lián)詞）。賓語從句是初中英語中最重要的一種從句，它內(nèi)容完整，句型結(jié)構(gòu)較為復雜，主句和從句時態(tài)搭配要求嚴格，在中考試題中頻頻出現(xiàn)。分別等于：no matter what, no matter how no matter where, no matter when二賓語從句結(jié)構(gòu):主句+that（可有可無）+肯定句結(jié)構(gòu):主句+if+一般疑問句結(jié)構(gòu):主句+疑問詞+肯定句。even if(=even though)▲ 在句末表示“然而”as表示“盡管”，從句的表語、狀語等成分要倒裝。但句后不能再用but。該結(jié)構(gòu)常見于： +形／副＋that +形＋a(an)＋單數(shù)名詞＋that ＋many/much＋復數(shù)名詞（不可數(shù)名詞）+thatsuch…that “如此的…以致于”表結(jié)果。無情態(tài)動詞表結(jié)果。 that, so…that, such…thatso that “以便”、“結(jié)果”表目的和結(jié)果。when, while后可以接分詞短語。when表時間，從句既可以用延續(xù)性動詞，又可以用瞬間動詞?！?結(jié)構(gòu)：主語+謂語+（連接詞）+賓語從句（用陳述句語序）Do you know who(whom)they are waiting for? I wonder whether(if)daughters are valued as much as sons in the +謂語+it+賓補+that+賓語從句用于這一結(jié)構(gòu)的及物動詞有consider, find, make, regard, see, take, think?！?例句：The news(that)he told me is really The news that our team has won the game is really 五、賓語從句★ 定義：句中及物動詞或介詞的賓語是一個完整的句子?！?從結(jié)構(gòu)上看，同位語從句是由連接詞引導，連接詞雖在從句中那個不充當任何成分，但不可省略?！?可接同位語從句的名詞一般是具有一定內(nèi)容含義的名詞：conclusion, evidence, fact, hope, idea, news, opinion, problem, promise, reason,truth等。同位語從句即表示同位語是一個完整的句子。The question is who can plete the difficult task.★ 注意：用because引導的標語從句僅限于以下一個句型 This/That/It is because(that)…I think it’s because you are doing too ，表語從句不能用why或because引導， reason why Hamlet is such a sucessful play is that it appeals to many different ，但可用as if引導?！?連詞：引導標語從句的連詞有that，whether, as if, 代詞who, what, which, 副詞when, where, how, why等?！?由it作形式主語，常用句型有：It is +名詞/形容詞/過去分詞+主語從句It is still a question whether she will e or is strange that you should like is still unknown which team will win the ，還有以下常用結(jié)構(gòu)： It turned out that… 結(jié)果是… It has been found that…已經(jīng)發(fā)現(xiàn)… It has been proved that…已經(jīng)證明… It happened/occurred that…恰好… It is wellknown that…據(jù)說…It is said/reported that…據(jù)說/據(jù)報道… It must be pointed out that…必須指出… It doesn’t matter whether…是否…都沒關系 It makes no difference whether…是否…毫無區(qū)別二、表語從句★ 定義：表語是一個完整的句子?！?連詞：引導主語從句的連詞有that, whether, 連接代詞有who, what, which, 連接副詞有when, where, how, why等。第四篇：英語從句用法小結(jié)英語從句用法小結(jié)一、主語從句★ 定義：主語從句時名詞性從句中的一種，指句中的主語是一個完整的句子。區(qū)別（2）同位語從句和先行詞是同等的關系；而定語從句是用來修飾先行詞，是從屬的關系。例如：Our teacher gave us some advice how we（should）use the suggestion came from the chairman that the new rule（should）be government gave the order that all these houses（should）be pulled down in three 。Word came that China launched its first manned spaceship on Oct 15，中國于2003年10月15日首次成功發(fā)射了載人飛船。例如：The news that our women volleyball team had won the championship encouraged us all ，而被別的詞語隔開，在語法上叫做分隔式同位語從句。s a question how he did 注：在名詞doubt“懷疑”后的同位語從句用whether連接；在no doubt“不懷疑”之后的同位語從句用that連接。He hasn39。We came to the decision that we must act at made a proposal that the meeting be 。在使用同位語從句時，應注意以下五個方面：一、常見帶有同位語從句的抽象名詞advice，announcement，argument，belief，claim（聲明、主張），conclusion，decision，evidence，explanation，fact，feeling，hope，idea，impression，information，knowledge，message，news，opinion，order，probability，promise，proposal，remark，reply，report，saying，statement（聲明、陳述），suggestion，thought，warning，wish，word二、同位語從句連接詞的選用在英語中，引導同位語從句的詞通常有連詞（that，whether），連接代詞(what ,who等)連接副詞（how，when，where）?！癐’ve settled everything。is going to be fine。is fine。es e。will e e。如：→Could you tell me how to get to the park?
