第五講百花齊放的名詞性從句李仕才一、名詞性從句的種類名詞性從句分為主語從句、表語從句、賓語從句和同位語從句，其作用相當于名詞，可分別作主句的主語、表語、賓語和同位語。1.主語從句：在句子中充當句子主語的從句Whoever is interested in making small inventions can join in it. 對小發(fā)明感興趣的任何人都可以參加。What he really means is that he disagrees with it. 2.表語從句：在句子中起表語作用的從句The last important thing you should remember is that you have to send the article to me before June 28th.你應(yīng)該記住的最后一件重要事情是在6月28日前把文章發(fā)給我。Today is what we can hold and make use of.今天是我們能夠抓住并能利用的。3.賓語從句：在句子中作及物動詞或介詞的賓語His uncle tells him that if his cousin wins the competition，the family will win an overseas tour for free.他的叔叔告訴他，如果他的表弟贏得了比賽，家人將贏得免費海外旅游。If I could interview him，I would ask him what made him an astronaut and how he was trained.如果我去采訪他，我會問他是什么讓他成為了一名宇航員以及他是如何訓(xùn)練的。4.同位語從句：在復(fù)合句中充當同位語的從句，用以解釋或說明前面名詞的具體內(nèi)容There is no doubt that everyone needs to make their contribution to environment protection.毫無疑問，人人都需要為環(huán)境保護做出自己的貢獻。He made a promise that he would never come late.他承諾永不會遲到。I have no idea how I can use the library.我不知道如何運用圖書館。二、名詞性從句的寫法在寫作中，如果我們能夠把兩個簡單句合并為一個含有名詞性從句的復(fù)合句，或者把一個簡單句擴展成為含有名詞性從句的復(fù)合句，對寫作都是一種質(zhì)的升華。名詞性從句在寫作時可采用“三步法”：第一步：寫出兩個簡單句。第二步：讓一個簡單句作從句，要注意和另一個句子的關(guān)聯(lián)性。第三步：把兩個句子合成復(fù)合句，要特別注意連接詞的選擇和從句的語序。示例第一步：寫出兩個簡單句。He said a lot at the meeting.His words were very attractive.第二步：讓句作主語從句，可轉(zhuǎn)換為“他在會上所說的話”，即what he said at the meeting。第三步：把句轉(zhuǎn)換的主語從句和句連在一起。What he said at the meeting was very attractive.跟 蹤 訓(xùn) 練.按要求把下列句子轉(zhuǎn)換成名詞性從句1.It disappointed everybody that he didnt turn up.(轉(zhuǎn)換為同位語從句)The fact that_he_didnt_turn_up disappointed everybody.2.To his surprise，the little girl knows so many things.(轉(zhuǎn)換為主語從句)What_surprises_him is that the little girl knows so many things.3.We find it necessary to help others when they are in trouble.(轉(zhuǎn)換為主語從句)It is necessary that_we_help_others_when_they_are_in_trouble.4.Winter is colder than summer.Do you know the reason？(轉(zhuǎn)換為賓語從句)Do you know why_winter_is_colder_than_summer?5.We have different opinions on this matter.(轉(zhuǎn)換為表語從句)This matter is where we differ.用適當?shù)倪B接詞填空1.Listening and speaking is _where my weakness lies when it comes to English.2.If I could interview him，I would ask him what made him an astronaut and how he was trained.3.What we need most are popular science books.4.I am wondering whether you can help me sell some.5.One day，she heard the news that the sports meeting would be held.用名詞性從句完成句子1.The news that_they_had_won_the_game soon spread over the whole school.他們贏得比賽的消息很快傳遍了整個學(xué)校。2.What_impressed_me_most was that they all had had professional training.使我印象最深的是，他們都經(jīng)過了專業(yè)培訓(xùn)。3.I_wonder_if/whether you can give me some advice on how to make friends.我想知道你能否給我提供一些如何交友的建議。4.The_reason_why some people become ill is_that they dont take exercise.一些人生病的原因是他們不鍛煉。5.No_one_can_deny_the_fact_that a persons education is the most important aspect of his life.沒有人能否認：教育是人生最重要的一方面。 3
