上一单元我们讲过，表示“这个”“那个” 等指示概念的词，叫指示代词。如this，that等。同样表示“这些”“那些”等指示概念的词也叫指示代词。英语中指示代词的用法同汉语中的情况相似, this(这个)和these(这些)一般用来指较近的人或事物, that(那个)和those(那些)则指较远的人或事物。Explanation---Is this (that) your sister?
---No, it isn’t.
---Yes, it is.
本句是询问“这(那)是你的……吗？”，
是一般疑问句，它的肯定回答为Yes, it is;
否定回答是No, it isn’t. Explanation 指示代词作主语并用于问句中时，回答一般用it代替this和that，they代替these和those。如：Is this her sister？ 这是她的姐姐吗？
No, it isn’t. 不, 不是。
Are these your brothers. 这是你的哥哥们吗?
Yes, they are. 是的。ExplanationThis is my friend.
这是我的朋友。
These are my friends.
这是我的朋友们。
在英语中句子中，注意单复数的一致性。如this 和friend 在意义上是单数，要选用相应的系动词is。these 和friends在意思上是单数，选用相应的系动词is。Explanation名词复数形式
在英语中，名词分为可数名词和不可
数名词。凡能用数数的人或物，其名词
就是可数名词。
可数名词可分为单数和复数两种形式：表示一个人或事物的名词用单数形式，
表示两个或两个以上的人或事物的名词
用复数形式。拓展名词复数构成方法：拓展名词复数构成方法：拓展※少数名词的复数形式是不规则的。例如：
