【文章內(nèi)容簡介】 he exam was because he was too careless.【正】 The reason why he failed in the exam was that he was too careless.【析】 主語為reason時，引導表語從句的關聯(lián)詞一般用that，不用because，構成The reason why/for which/that/for . . . is that . . . 句型。because引導名詞性從句只用于It/This/That is because . . . 結構。 5.【誤】 It is unknown that where we will have the meeting.【正】 It is unknown where we will have the meeting.【析】 名詞性從句一般只能用一個引導詞，連接詞that與連接副詞不可并用。 6.【誤】 The problem is when will he e back.【正】 The problem is when he will e back.【析】 名詞性從句應該用陳述句語序，即“引導詞 + 主語 + 謂語”。 7.【誤】 Could you tell me which was the way to the Science Museum?【正】 Could you tell me which is the way to the Science Museum?【析】 當主句為過去時態(tài)的時候，賓語從句中要用過去的某種時態(tài)。但該句中的could不是表示過去，而是表示一種委婉的語氣，故賓語從句中的謂語動詞應用一般時態(tài)。8.【誤】 If he is an engineer is unknown.【正】 Whether he is an engineer is unknown.【析】 if不能用來引導主語從句，在表示“是否”這一意義時要用whether。 9.【誤】 I have been worrying about if I have hurt her feelings.【正】 I have been worrying about whether I have hurt her feelings.【析】 if和whether引導動詞后的賓語從句時可互換。但介詞后的賓語從句及主語從句、表語從句、同位語從句只能用whether引導。10.【誤】 What he needs are enough time and what I need is enough books.【正】 What he needs is enough time and what I need are enough books.【析】 名詞性從句作主語時，謂語動詞常用單數(shù)。但what引導主語從句時，若表語為單數(shù)名詞或不可數(shù)名詞，則謂語動詞用單數(shù)；若表語為可數(shù)名詞復數(shù)，則謂語動詞常用復數(shù)。 11.【誤】 No matter who es to visit the exhibition is wele. 【正】 Whoever es to visit the exhibition is wele. 【析】 “No matter + 疑問詞”結構只能引導讓步狀語從句，“wh + ever”既可引導讓步狀語從句，也可引導名詞性從句。 12.【誤】 I’ll make known to all that you were not honest. 【正】 I’ll make it known to all that you were not honest. 【析】 當賓語從句前有形容詞或名詞作賓補時，須用it作形式賓語，而將真正的賓語從句后置。其句式為：主語 + 動詞 + 形式賓語it + 賓補（形容詞或名詞）+ 賓語從句。又如：I found it quite pleasant that I worked with him. 13.【誤】 He is said that he has gone to America. 【正】 It is said that he has gone to America. 【析】 It is said that是一固定句型，it為形式主語，不可用其他詞代替。14. 【誤】 My suggestion is that we will learn more words by heart. 【正】 My suggestion is that we should learn more words by heart. 【析】 主語為suggestion, advice, order, proposal等名詞時，表語從句要用虛擬語氣，即用“（should）+ 動詞原形”的結構。這些名詞的同位語從句也要用虛擬語氣。15.【誤】 Why we decided to put off the meeting is because we had some difficulty in preparing it.【正】Why we decided to put off the meeting is that we had some difficulty in preparing it.【析】why引導主語從句時，表語從句要用that引導。練習一： 單句改錯 the earth turns around the sun are known to all. the meeting will be held haven’t been known yet. didn’t know that you will e. said that he is writing a story. you tell me when will he arrive? can begin to see why does English have such strange rules.練習二：用that / what填空： he wants is a book.2. ______ he wants to go there is obvious. result is ______ we won the game. is _____ we want to know. _____ he told us true ? should pay attention to ______ the teacher is saying.7.
