探究一：指示代词用法
1.指示代词 表示“这个”“那个”“这些”“那些”等指示概念的词,叫指示代词。如this，that, these, those等。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。

探究一：指示代词用法
2. 学习指示代词, 应注意以下几点:
①this与is, these与are没有缩写形式。This is a Chinese car. 这是一辆国产轿车。
②指示代词作主语指物并用于问句中 时，回答一般用it代替this和that，they代替these和those.
3. 指示代词在句子中的用法
在句子中指示代词可以充当主语、定语、宾语或表语。例如：
This is a pear.(作主语) 这是一个梨。
These video clips are very interesting and those ones are not.(作定语)
这些光碟很有趣, 那些没意思。
I like this very much.(作宾语)我很喜欢这个。
Oh, it’s not that.(作表语) 哦, 不是那个。

名词性物主代词
mine，hers，yours 等是名词性物主代词，相当于一个名词，可以在句子中单独使用。它相当于“形容词物主代词 + 名词”。而形容词性物主代词只能和名词在一起使用。例如：
This is your ruler. It’s not my ruler. (= This ruler is yours. It’s not mine.)
Those aren’t his books. They’re her books. (= Those books aren’t his. They’re hers. )
I my mine
you your yours
she her hers
he his his
