重点：批示代词：this，that，these，those
人称代词：I，she，he，they
连系动词be及其缩略形式
难点：批示代词：this，that，these，those
知识点：
Those are my parents. 那是我父母。
those批示代词意为“那些”，是批示代词that复数。this复数形式是these
当第三者给互相不结识两人做简介时，通惯用this is/that is,而不用，she is/he is.
this
指代较近一种人或物
that
指代较远一种人或物
these
指代较近各种人或物
those
指代较远各种人或物
this that 为单数意义 与单数名词连用 these those 为复数意义，与复数名词连用，用来简介两个或两个以上人或物，意为“那些是，这些是……’

规律 Yes/No，改 this/that 改it

反 主语与be动词反过来
提问人用who
who背面用is 还是are取决于be动词背面名词单复数
who is/ are
Who is Zhai Wenfei?
Who is this boy?
Who is she?
Who are they?
And who’s he?尚有她是谁？
Who 疑问代词，意为“谁”
who宾格whom，在句中作宾语时，两者在口语中可互换，所有格whose
Well，have a good day！好吧，祝你们玩高兴！
well用在句子开头，其后加逗号，用在重新开始说话。意为“好吧，噢”
have 意为“经历，经受”
have a good day祝愿用语类似用法尚有
have a good time!
have a good dream!
have a good luck!
have a good trip!
4. These are my parents and this is my grandma. 这是我父母，这是我祖母。

强调重复，持续。
They read and read.

拓展：
1)名词所有格重要用途是用来表达所关于系。
This is my teacher's desk. 这是我教师课桌。 Tom's room汤姆房间
(2)名词所有格还可以表达类别。
the teacher's boo
