表示“這個(gè)”，“那個(gè)”，“這些”，“那些”等意思的代詞叫做指示代詞。指示代詞分單數(shù)(this / that)和復(fù)數(shù)(these / those)兩種形式

2、指示代詞的用法區(qū)別
(1) this和these一般指在空間和時(shí)間上較近的事物，that和those一般指在空間和時(shí)間上較遠(yuǎn)的事物。

Please come this way. We'll go in by that door. 請(qǐng)這邊走，我們從那扇門進(jìn)去。
In those year they led a hard life. 在那些歲月里，他們生活得很艱難
2) this和these常指后面將要講到的事物，有啟下的作用，that和those常指前面已經(jīng)講到過的事物，起承上的作用。
例：I shall say this to you: he is an honest man. 我將對(duì)你說這一點(diǎn)：他是一個(gè)誠實(shí)的人。
He felt ill. That is why he didn't come. 他病了，那就是他沒來的原因。
He broke the glass, and that cost him five dollars. 他打破了玻璃，那花費(fèi)了他5美元。
(3) that和those有時(shí)可用來代替前面提到過的東西，以避免重復(fù)這個(gè)名詞：

(4) 在電話中，this表示打電話者，that表示接電話的對(duì)方。
例：A: Hello! This is Bob (speaking)。喂，我是鮑勃。
B: Who's that please? 請(qǐng)問是哪位？(美語用Who's it?或Who's this?)
3、such也是一個(gè)指示代詞，在句子中可用作：
(1) 定語：

(2) 主語：

(3) 表語：
