【文章內(nèi)容簡介】 不僅可以作為形式主語，還可以作為形式賓語而真正的賓語that 從句則放在句尾，特別是在帶復(fù)合賓語的句子中。例如：We heard it that she would get married next 。 從句的動詞這類動詞有allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。這類詞后可以用不定式或動名詞作賓語，但不可以用that引導(dǎo)的賓語從句。如：正確表達：I admire their winning the ：I admire that they won the 有些動詞不可用于“動詞＋間接賓語＋that從句“結(jié)構(gòu)中，常見的有envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。例如：正確表達：He impressed the manager as an honest ：He impressed the manager that he was an honest 若主句謂語動詞為think, consider, suppose, believe, expect, fancy, guess, imagine等，其后的賓語從句若含有否定意義，一般要把否定詞轉(zhuǎn)移到主句謂語上，從句謂語用肯定式。例如：I don’t think this dress fits you 。表語從句在復(fù)合句中作表語的名詞性從句，放在系動詞之后，一般結(jié)構(gòu)是“主語＋連系動詞＋表語從句”?？梢越颖碚Z從句的連系動詞有be, look, remain, seem等。引導(dǎo)表語從句的that常可省略。另外，常用的還有the reason is that? 和It is because 等結(jié)構(gòu)。例如： 1)The question is whether we can make good preparation in such a short )This is why we can’t get the support of the )But the fact remains that we are behind the other )The reason he is late for school is that he missed the early 同位語從句就是在復(fù)合句中作名詞的同位語的名詞性從句。同位語從句對于名詞進一步解釋，說明名詞的具體內(nèi)容，一般由that引導(dǎo)，例如：1)The king’s decision that the prisoner would be set free surprised all the )The order that all the soldiers should stay still is given by the 同位語從句有時可以不緊跟在它所說明的名詞后面，而是被別的詞隔開。例如：He got the news from Mary that the sports meeting was put (1)定語從句中的that既代替先行詞，同時以在從句中作某個成分（主語或賓語），而同位語從句中的that是連詞，只起連接主句與從句的作用，不充當(dāng)句中任何成分。(2)定語從句是形容詞性的，其功能是修飾先行詞，對先行詞加以限定，描述定的性質(zhì)或特征；同位語從句是名詞性的，其功能是對名詞進行補充說明。例如： 1)The news that he told me is that Tom would go abroad next year.（他告訴我的消息是湯姆明年將出國。）（第一個that引導(dǎo)的從句是定語從句，that在從句中作賓語）2)The news that Tom would go abroad is told by him.（湯姆將出國的消息是他講的。）（同位語從句，that在句中不作任何成分）高一英語名詞性從句專項練習(xí)1．____he does has nothing to do with matter what manager came over and asked the customer how____ the quarrel came about quarrel had e about the quarrel e about the quarrel e about is ____makes thing work.. has been put forward ____ more middle school graduates will be admitted into is ___the Shenzhou V Spaceship which have no idea at he has gone did he go place has he gone has he gone doctor did a lot to reduce the patient’s fear ____he would die of the which that order came ___the soldiers ____the small village the next 。had to leave。should leaveC./。must leave。should leave no possibility ____Bob can win the first prize in the 。that。that。whether 。whether question came up at the meeting_____ we had enough money for our _____he said really true?
