关于名词性从句的基本语法知识,同学们在高二就有过比较详细的学习。这里主要讲讲同学们在学习中应该注意的问题,以及在解题时的一些解题技巧。 一、概述 1,主语从句 What he wants is a piece of paper. It is believed that he can solve the problem. 注:1)从句作主语谓语动词用单数。 2) 连接词that引导主语从句时,that不可省略。 3)在表示"是否"的含义时,主语从句只能用whether, 不能用if。 2,宾语从句 I don't know how to solve the problem. Do you know where he lives? 注:宾语从句用正常语序。 3,表语从句 The problem is who can help me. This is why I came here. 注:1)连接词that引导表语从句时,通常不可省略,口语中可以省。 2)表语从句只能用whether,不能用if。 3)表语从句还有两个连接词,as if和because。如: It looks as if it is going to rain. 看来要下雨。 That is because he missed the morning train. 那就是因为他没赶上早晨的车。 4,同位语从句 I have no idea where he went. I heard the news that he would come. 注:同位语从句用that引导,常跟在fact, idea, news, promise, thought, message, hope, belief, doubt等词后,that在从句中不作任何成分。同位语从句有很多引导词,但which 不是同位语从句的引导词。 二、做题技巧 做名词性从句主要看从句中缺少什么成分,缺少什么成分,补什么成分。如: 1.__________ you need is more practice. 2.__________ we shall have our sports meet is still a question. 3.__________ we need more equipment is quite obvious. 4.That was __________ they were defeated. 5.The fact remains __________we are behind the other groups. 6.I have no idea __________we want to go next Sunday. 7.We expressed the hope __________ we would visit the city again. 8. _________ is troubling me is __________ I don't have much experience in this kind of work. 9.That is __________ the key lies. 10.That is __________ we are firmly against. 讲解: 第1题填What,what在这里的意思是"……东西",在从句中作need宾语。what引导的名词性从句做句子的主语。 第2题When,在从句中作时间状语。引导主语从句。 第3题填That,由于主要从句we need more equipment是个完整的句子,不缺宾语,所以这里用that引导主语从句。注意,这是一个同学们常会错的问题。 第4题填how,在从句中作状语。或why在从句中作原因状语。 第5题填that,这里是that引导的表语从句。 第6题填where,在从句中作go的地点状语。 第7题填that,that引导的hope的同位语从句。 第8题第一个空填what,第二个空填that。这道题把what和that的区别都讲到了,同学们可以留意一下。What在主语从句中作主语;that在表语从句中不作成分。 第9题填where,where在从句中作地点状语。 第10题填what,what在从句中作介词against宾语,what的意思是"……的东西"。 【考题解析】 1.─I drove to Zhuhai for the air show last week. ─Is that _____ you had a few days off ? (NMET 1999) A. why B. when C. what D. where 【答案】A 【解析】从题干和所给的4个选择中不难看出本题考查的是表语从句。"I drove to Zhuhai for the air show."提出一个事实,而第二句表明"I"不在的原因。故答案为A.why。 2.─It was _____ he said _____ disappointed me. (上海 1999) A. what; that B. that; that C. what; what D. that; what 【答案】A 【解析】该句考查的是强调句和主语从句。该句强调的是句中的主语,而该句的主语又是一个从句。从这个结构中可以看出第二个空和"It was"构成强调句,故第二个空应该是that;第一个空和"he said"构成主语从句;在这个从句中"said"一词后缺少宾语,故答案为A.what;that。
