In conclusion,________.,名詞性從句易錯點分析 一、that引導的定語從句與同位語從句的區(qū)別 同位語從句通常是在一個名詞,如fact,idea, news, hope, belief, thought, doubt, proof等后,對其作進一步的解釋。 I have no idea that you were here. He can’t answer the question how he got the money.,①Along with the letter was his promise that he would visit me this coming Christmas. ②Do you still remember the chicken farm that we visited three months ago? 解釋:在句①中,that引導同位語從句解釋說明promise的內(nèi)容,that不充當任何句子成分,只起連接作用;而在句②中,that引導的定語從句對先行詞the chicken farm起修飾作用,先行詞在從句中作visited的賓語。,二、名詞性從句中,關于it作形式主語和形式賓語的易錯點 1.名詞性從句作主語或賓語時,為保持句子平衡,常用it作形式主語或形式賓語。以下是常見的用it作形式主語的復合結構: ①It is+名詞+that從句 It is a fact/pity/shame/no wonder/good news.that. ②It is+形容詞+that從句 It is necessary/strange/important/wonderful/possible/likely that.這類句型中的謂語動詞多為“( should)+動詞原形”結構。 ③It is+過去分詞+that從句 It is said/reported/decided/believed that.,④It+不及物動詞+that從句 It seems/happened/doesn’t matter/has turned out that. It’s a pity that he doesn’t come to give a speech. (it作形式主語) We think it possible that you can finish the job today. (it作形式賓語) It happened that her mother was away. It has turned out that he was the murderer. 2.謂語動詞appreciate, dislike, hate, like, love, make等后接由if或when引導的賓語從句時,往往在從句前加上形式賓語it。 I would appreciate it if you could come to my birthday party.,【單項填空】 It is obvious to the students________ they should get well prepared for their future. A. as B.which C.whether D.that,D,三、that和what的區(qū)別 連詞that在從句中不作任何成分;what可作主語、表語或賓語等。 【單項填空】 ①A modern city has been set up in ________was a wasteland ten years ago. A. what B.which C.that D.where ②Great changes have taken place in that school. It is no longer ________it was 20 years ago,________ it was so poorly equipped. A. what; when B.that; which C.what; which D.which; that,A,A,③—Is there any possibility ________you could pick me up at the airport? —No problem. A. when B.that C.whether D.what,B,四、名詞性從句的語序 名詞性從句通常用陳述句語序。 【單項填空】 He asked ________for the violin. A.did I play how much B.I paid how much C.how much did I pay D.how much I paid,D,五、if和whether的用法比較 ①if引導賓語從句和條件狀語從句。 ②whether引導主語從句、表語從句、賓語從句和同位語從句。 【單項填空】 At first he hated the new job but decided to give himself a few months to see________ it got any better. A. when B.how C.why D.if,D,- 配套講稿:
