【正文】 第一篇：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?！?位置：它可以放在主句謂語動詞之前，但多數(shù)情況下由it作形式主語，而把主語從句放在主句之后?！?連詞：引導(dǎo)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?！?例句：That she was able to e made us very she will e or not is still a we need is more will go makes no team will win the match is still they will start is not known she has gone is a this happened is not he did that wasn’t.★ 引導(dǎo)主語從句的that不作成分，但不能省略?！?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(guān)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。，由引導(dǎo)，有時可省略that.★ 位置：從句位于系動詞之后?！?連詞：引導(dǎo)標語從句的連詞有that，whether, as if, 代詞who, what, which, 副詞when, where, how, why等?！?例句：That fact is(that)she never liked could be this part of the ice sheet is not necessarily sensitive to golbal 。The question is who can plete the difficult task.★ 注意：用because引導(dǎo)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(dǎo)， reason why Hamlet is such a sucessful play is that it appeals to many different ，但可用as if引導(dǎo)。He looked as if he was going to 、同位語從句★ 定義：同位語是一個名詞，表示與前面名詞相同的人或物，如“my friend John”中，John 是friend的同位語，the Yangtze, the longest river of China”中，river 是Yangtze的同位語。同位語從句即表示同位語是一個完整的句子?！?位置：同位語從句跟在名詞后面，進一步uom該名詞的具體內(nèi)容，或?qū)υ撁~作進一步解釋。★ 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?！?連詞：that(不能用which)，連接副詞when, how, why, whether, 連接代詞what.★ 例句： His delay is due to the fact that the car went wrong news that our team has won the match is asked the reason why there was a problem whether this material can be used in our factory has not been has no idea what a remarkable woman Mary 、同位語從句與定語從句的區(qū)別★ 從意義上看，同位語從句是名詞性從句，是對一個名詞加以補充說明，而定語從句是形容詞性的，是對一個名詞加以修飾和限定。★ 從結(jié)構(gòu)上看，同位語從句是由連接詞引導(dǎo)，連接詞雖在從句中那個不充當任何成分，但不可省略。而定語從句中的關(guān)系代詞代替先行詞，并在句中充當成分（主語或賓語），充當賓語時?？墒÷??！?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?！?連詞：連接賓語從句的連詞有that, whether, if, 連接代詞有 who，whose, what, which 以及連接副詞有when, where, how, why?！?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。We find it necessary that we practise speaking English every always take it for granted that he can pass the exam without hard work.第二篇：同位語從句用法小結(jié)同位語從句用法小結(jié)在復(fù)合句中充當同位語的名詞性從句稱為同位語從句。在使用同位語從句時，應(yīng)注
