this/that的替代用法 知识点

一、this作替代词的用法:this用作代词可用以指叙述中的人或事物,即指前面提到过的人或事物或下文提及的事物;this一般作主语时才指人;在电话用语中, this用来指代自己。当陈述部分的主语是this时,附加疑问部分的主语须用it。
例如:①This is, in part, my own mistake.在某种程度上来说,这是我自己的错。
②Now don't laugh when you hear this.听了这个你不要笑。
二、that作替代词的用法 
1.that用来替代前面提到的特指的事物,所代替的名词可以是可数名词,也可以是不可数名词。代替可数名词可以用the one替换。但其前面不可用任何限定词修饰。
例如: ①The population of China is larger than that of Japan.中国的人口比日本多。(that代替不可数名词population,不可用the one替换)   
②The headteacher in your class is younger and more active than that in theirs.你们班的班主任比他们班的更年轻更活跃。(that代替可数名词headteacher,可用the one替换)  
2.that在并列分句中,可以替代前面某一个名词或整个句子内容,可用it 替换,也可改为非限制性定语从句。
例如:  ①She heard a terrible noise,and that brought her heart into her mouth.她听到一阵可怕的声音,她的心提到了嗓子眼。(that替代前面的名词noise)   
②They said they had discussed the problem,and that was impossible.他们说他们讨论过这个问题,那是不可能的。(that替代前面整个并列分句They said...)   
3.that在定语从句中,可作关系代词,代替某个先行词(人或物)。
例如:   ①The lady that came to our class is from Australia.来我们班的那位女士来自澳大利亚。(that指代先行词lady)   
②A clock is a machine that tells people the time.时钟是告诉人们时间的机器。(that指代先行词machine)
