(一)指示代词this, that, these, those
含有指示概念的代词叫做指示代词。this, that, these和those都可作指示代词，分别表示“这个”、“那个”、“这些”和“那些”。指示代词在句子中可作主语、宾语、表语、定语等成分。
指示代词是表示“这个；那个； 这些；那些”的代词。其中，this(这个) 和these(这些)指离说话人较近的人或事物；
【重点】
语法讲解
that(那个)和those(那些)指离说话人较远的人或事物。
eg：This is Jenny and that is Alice.
这是珍妮，那是艾丽斯。
These are pears and those are apples.
这些是梨，那些是苹果。
That ________ my aunt.
These ________ our bikes.(is, are)
is
【解析】本题采用主谓一致法。that后用单数is, these后用复数are。
指示代词this, that 作主语时，系动词be用单数形式is，同时后面的名词用单数形式；当these，those作主语时，系动词be用复数形式 are, 同时后面的名词用复数形式。
are
【重点】
在回答主语是this或that 的一般疑问句或特殊疑问句时，在答语中用it代替问句中的this或that 。当回答主语是these或those的问句时，在答语中用they来代替句中的these或those。
【易错点】
who用作疑问代词，指人，可用作主语、宾语、表语等成分。
(二)who引导的特殊疑问句
who用于实义动词前作主语，且提问
时常用作第三人称单数。
【易错点】
—________likes science
—My friend Rosie.
Who　
【解析】由答语可知问句为对人的提问，故填Who。
英语中，名词分为可数名词和不可数名词。不可数名词没有复数形式；可数名词在表示多个人或物时用复数形式。可数名词的复数形式一般是在词尾添加 s或 es构成。
