Grammar
（1）指示代词this, that作主语时, be动词用单数形式, 且后面名词用单数形式。
e.g. 这是一本书。
那是我的爷爷。
This is a book.
That's my grandfather.
★ 注意
that is = that's
但是 this is 没有缩写形式
（2）回答主语是this或that的一般疑问句或特殊疑问句时, 答语中用 it 代替句中的 this 或 that 。
回答主语是these或those的问句时, 答语中用they 代替句中的 these 或 those 。
e.g. —What are these
— are flowers.
They
e.g. —Are these your grandparents
—Yes, are.
they
e.g. —What's this in English
— is a cup.
It
指示代词的句型转换
1. 一个句子中，如果主语是“this/that/these/those+名词”，则该句子常可变换成指示代词作主语的句子。
This is Sally’s picture. 这是萨莉的照片。
Those dogs are my cousin’s. 那些狗是我堂哥的。
Those are my cousin’s dogs. 那些是我堂哥的狗。
This picture is Sally’s. 这张照片是萨莉的。
2. 单数句变复数句：
① this变these，that变those；
② be动词is变成are；
③ 可数名词单数变为复数；
④ 不定冠词a/an要去掉。
These are cats.
Those are erasers.
This is a cat.
That is an eraser.
可数名词单数变复数规则
(1)一般情况下在名词后面加-s。

(2)以辅音字母加y结尾的名词，先将y改为i，再加-es。
family→families
(3)以s, x, ch, sh结尾的名词,其后加-es。
watch→watches box→boxes(盒子)
(4)以f或fe结尾的名词，先将f或fe改为v，再加-es。
knife→knives(小刀) leaf→leaves(树叶)
(5)以o结尾的名词，有的加-es，有的直接加-s。
tomato→tomatoes(西红柿) hero→heros(英雄)
photo→photos(照片)
(6)特殊情况。
man→men(男人) child→children(儿童)
Hi, I’m Sally.
This is my mother.
