名词性从句的注意要点.docVIP

一、八点注意?(一) 注意不可多that连接代词who, whom, which, whose, what;连接副词how, why, when, where; 连接词if, whether; 所有这些词前，不可再用that。例如：　　 He doesn’t know that when they arrived here.(去掉that)(二) 注意不可少that　　 引导名词性从句的that在句子中无具体意思，但在下列情况下，that不可省略：1. 宾语从句被分隔时； 2. 宾语从句不止一个时； 3. 引导主语从句、表语从句或同位语从句时。例如下列句子中不可省略that：?I don’t doubt, in any case, he keeps his word.(应在he前加上that)Everyone could see what was happening and poor Tom was nearly frightened. (应在and后加上that)　　 The earth goes round the sun was not widely accepted at that time.(应在句首加上That)　　 The problem is fuels like coal and oil cause a lot of pollution.(应在is 后加上that)　　 We heard the news our team had won.(应在news后加上that) （三）引导词that的省略 ?1.引导宾语从句时，that可以省略；但引导主语从句、表语从句和同位从句时，that通常不省略。例如：--Now we all know (that) capitalists brought in large quantities of wealth by taking possession of the surplus value --I first heard the story from my neighbor that the head of the county was arrested. 2.当用it作形式主语、宾语时，引导词that通常也不省略。 例如：--It was really strange that a quick was turned into nothing in a flash by the magician. --Do you think it necessary that we should make up the missed lessons? (四) 注意that与what的用法 引导主语、宾语或表语从句时，what在从句中要充当句子成分；而that引导主语、宾语、表语和同位语从句时，不作任何成分，只起语法连接作用。that没有意义，在句中只起引导的作用，不作成分；what意为“……的东西（事物）”，在从句中可作主语或宾语、表语、宾语补足语。例如：　　 That he needs is your help.(把That改成What)?1) ________we can’t get seems better than_ _______we have.　　 A. What; what??? B. What; that? ?C. That; that D. That; what2) ________ fashion differs from country to country may reflect certain cultural differences.　　 A. What?? B. That?? C. This??? D. Which?3) People were perhaps more honest a long time ago when life was very different from ________it is today.　　 A. which???? B. that?? ?C. what? ?D. how4) The word media basically refers to ________we commonly call newspapers, magazines, radios and televisions.　　 A. which??? B. what??? C. why???? D. that?(五) 注意区分that, because和why　有些名词如reason, cause作句子的主语时，其后的表语从句常用 that引导，不可用because; because引导表语从句时用于句型That’s
