指示代词

英语中用来表示“这个”、“那个”、“这些”、“那些”等指示概念的代词称为指示代词。

指示代词是表示指示概念的代词，即用来指示或标识人或事物的代词。指示代词与定冠词和人称代词一样，都具有指定的含义，用来起指示作用，或用来代替前面已提到过的名词。如：This is my sister. 这是我的姐姐。

That is my brother. 那是我的哥哥。

These are teachers. 这些是我的老师。

Those are my friends. 那些是我的朋友。

单数

复数

近指

this

these

远指

that

those

我们所学的指示代词有：

近指: this these 远指: that those

指示代词的用法及注意事项：

（1）指示代词既可作限定词又可做代词，例如：

　　限定词：This girl is Mary. Those men are my teachers.

　　代词：　This is Mary.　Those are my teachers.

（2）this和these指在时间或空间上较近的人或物，that和those指在时间或空间上较远的人或事物。例如：

　　This is a pen and that’s an eraser. 这是一支笔，那是块橡皮擦。

This is a boy and those are girls. 这是个男孩，那些是女孩。

（3）打电话过程中，介绍自己时通常用this指代“我”，不用代词I；询问对方时用that指代“你”，不用代词you。例如：

　　—-Hello. This is Mary. Who’s that? 喂，我是玛丽。你是谁？

—-This is Tom. 我是汤姆。

（4）在回答指示代词作主语的一般疑问句时，不管指示代词指人还是指物，答语中都用it或they。例如： 　—-Is this a ruler? —-Yes, it is.

（5）向别人介绍某个人时，要说“ This is ….”，不能说“ He is ….”或“ She is ….”。介绍两个人时，先用“ This is ….”介绍一个人，然后用“ That is ….”介绍另一个人。如：

　　This is Li Ming. Li Ming, this is Wei Hua. 这是李明。李明，这是魏华。

This is my brother and that is my sister. 这是我哥哥，那是我妹妹。
