this that these those的用法
答案
这四个单词都是指示代词
单数形式:this(这个),that(那个)
复数形式:these(这些),those(那些)
this(these)和that(those)的区别
通常this(these)指离说话人较近的物品,that(those)指离说话人较远的物品.指示代词既可以单独使用,也可以与名词连用.例如:
Xiaofeng,this is Xiaoyun,my friend.
These people are my friends.
That is Tom near the door.
Those people in the car are his brothers and sisters.
