高中英语难点从句中怎么区分that和whatWord文档格式.docx

1、 3.With his work completed, the businessman stepped back to his seat, feeling pleased _ he was a man of action.A. which B. that C. what D. whether 4.It is what you do rather than what you say _ matters.A. that B. what C. which D. this 5.His plan was such a good one _ we all agreed to accept it.A. so

2、 B. and C. that D. as上面5个题中的前四个题，在选项中都同时出现了what和that，如何选择呢？第1题为答案A。考查名词从句连接代词what的使用。“十年前是一片荒地的地方建起了一座现代化的城市”。作介词in的宾语不能用that，因为名词从句中that不做任何成分；连接代词what引导一个宾语从句，“是一个什么样的地方”；第2题为答案A。考查定词从句关系代词that的使用，“因为记忆不好，你告诉我的，我都给忘了”。句中先行词为“all”，that为关系代词，意指all，在从句中做宾语；第3题答案为B。考查名词从句从属连词that的使用。“他很得意自己是个干事的人。”陈述了

3、一个事实，故选择从属连词that 第4题为答案A。考查强调句结构中的that。“It is （was） + 所强调的成分 + that （who） + 其他成分。” 第5题为答案C。考查结果状语从句中的从属连词that。“他的计划非常好，我们都同意接受。 从上面的分析中，我们不难看出，“that”一词非常活跃，在定语从句、名词从句、状语从句和强调句中都有使用；而命题设项时，“what”又常常用来作为干扰，所以，要想辨清“that” 和“what”这两个词，突破复合句式的这个难点，就要注意：一、定语从句的关系代词中没有what，所以要牢记what不会引导定语从句。例如： 1.The though

4、t of going back home was kept him happy while he was working abroad.A.that B.all that C.all what D.which 答案为B。这里的all是先行词，而that是关系代词，在从句中做主语。很多同学将此题误选成了C。需要注意的是，C选项前面要是去掉all，则变成了what引导的名词从句，则就是对的了。 2.You can only be sure of_ you have at present; you cannot be sure of something _ you might get in the

5、future. 2007 安徽卷 A. that; what B. what; / C. which; that D. /; that前一个空为名词从句连接代词what，（从句做of的宾语，what又为get的宾语），后一个空为定语从句（先行词为something，关系代词做get的宾语，关系代词省略）。 二、名词从句中同时存有that和what这两个连接性词语，能够从其语法地位和意思上来辨别。 that 引导名词性从句时，没有任何含义和语法作用，仅仅提示引导了名词从句；而what引导名词性从句时，在主从句中都要充当一定的句子成分，what的意思是“什么”1.The mountain is n

6、o longer _ it used to be. A. which B. that C. what D. as 答案C 。“山不是以前那个样子了”。以前“什么样”，对应了what。 2.There is much chance _ Bill will recover from his injury in time for the race.A. that B. which C. until D. if 答案A。that引导的名词从句陈述事实，说的即是前面的chance，为同位语从句。三、定语从句与同位语从句中that的区别，主要看that在从句中有没有语法作用。定语从句中的关系代词that在

7、句中做宾语或主语，有时能够与 which 互换。同位语从句中的连词that只起连接作用，在从句中不担当任何句子成分；而如果句子是同位语从句，就应用连词that而不能用which。同位语从句一般放在表具体含义的名词如：fact、suggestion、truth、possibility、idea等后面，解释名词的含义或内容，而定语从句仅仅对先行词的限定和修饰。 The football star Henry expressed the hope that he would come to visit China again in 2008. 同位语从句，从句就是hope的内容； The hope

8、the football star Henry expressed is that he would come to visit China again in 2008. 定语从句，从句修饰hope，是“表达的”愿望。 再如： 1.Its thirty years since we last met. But I still remember the story, believe it or not, _ we got lost on a rainy night. A. which B. that C. what D. when 同位语从句，解释story。 2.I still remembe

9、r the big names in the stories _ my mother told me when I was young. A. when B. that C. what D. where 定语从句，意指stories，做told的宾语。 名词性从句中that和what的用法区别 一。that 引导的名词性从句 首先，连接代词that除引导第一个宾语从句时能够省略外，引导其他各类名词性从句皆不能省略。例如： It is required in the regulations that you should not tell other people the password of

10、 your e-mail account. - Dont you think it necessary that he go home at once? - but the problem is that there is no car. There is much chance that Bill will recover from his injury in time for the race. Our English teacher told us （that） we all did very well in the examination and that ten of us got

11、full mark. 以上四个句子中，that 分别引导主语从句，表语从句，同位语从句和宾语从句，除在第四个例句中第一个that 能够省略外，其他的that 均不可省略。 其次，在引导名词性从句时，that不作句子中的任何成分。 Nobody believed his reason for being absent from the class that he had to meet his uncle at the airport. 该句中，that引导同位语从句，但在句中不作任何成分。 It is our belief that improvements in health care wi

12、ll lead to a stronger, more prosperous economy. 该句中，it 是形式主语，that引导的主语从句才是整个句子的真正主语，that在句中不作任何成分。 最后，在引导名词性从句时，that没有任何词汇意义。 A warm thought suddenly came to me that I might use the pocket money to buy some flowers for my mothers birthday. Danby left word with my secretary that he would call again i

13、n the afternoon. 在以上两个考例中，that仅起引导同位语从句的作用，没有任何词汇意义。 综上所述，that 在引导名词性从句时具有三大特点：不可省略，不作成分，没有词义。二。 what引导的名词性从句首先，what 引导名词性从句时，what 在句中不省略。这个用法与that引导名词性从句时的用法不尽相同。 He spoke proudly of his part in the game, without mentioning what his teammates had done. what 在该句中引导宾语从句，what 不可省略。 Great changes have taken place in that school. It is no longer what it was 20 years ago, when it was so poorly equipped. what在该句中引导表语从句，但在句中不可省略。 其次，what 引导名词性从句时，具有词汇意义。这是what 与that 引导名词性从句的重要区别之一，What 一般指“-的东西/事情/人/时间/地点等
