Is this your pencil
Tip:
mine = my + n.
mine相当于my加一个名词。
It’s my pencil.
提示：让学生在情景中感受mine名词性物主代词，借助学生的物品加强感知：询问第一位同学（基础要比较好）Is this your 。。。
学生回答：Yes, it is. It’s mine. 再指着ppt引导学生说出It’s my。。。。，再依次抽几位同学，第3位就可以抽基础中等的啦。
由浅入深，先感知mine有利于后续感知hers his 等。
No, it isn't.
It's hers.
Is this your ruler
Tip:
hers = her + n.
hers相当于her加一个名词。
It’s her ruler.
提示：让学生在情景中感受mine名词性物主代词，借助学生的物品加强感知：询问第一位同学（基础要比较好）Is this your 。。。
学生回答：No, it isn’t. It’s hers.
同样的方式再指着ppt引导学生说出It’s her。。。。，再依次抽一些同学

It's his.
Is this your eraser

his = his + n.
注意his两种形式是一样的哦。
It’s his eraser.
提示：让学生在情景中感受mine名词性物主代词，借助学生的物品加强感知：询问第一位同学（基础要比较好）Is this your 。。。
学生回答：No, it isn’t. It’s his.
同样的方式再指着ppt引导学生说出It’s his。。这里可以幽默一点和学生互动It’s his. It’s his book. which one is right both of them is ok, because...再强调一下tip. 再依次抽一些同学加强感知。
然后学生已经感知了his，hers, mine的意思和用法了，可以随意拿起教室里的其他物品让学生回答这几个一般疑问句，检测学生，能回答了就说明理解了。
Yes, they are.
Are these
your books
提示：前面学生已经感知了his，hers, mine的意思和用法了，这里让学生感知在情景中感受these 的yes or no问答,
同样的方式借助教室的pens, books 操练Are these， are those....
No, they aren't.
They are his.
Are those
your keys
Is this his bag
No, it isn't.
It's mine.
提示：操练了Are these， are those....，最后落脚点到mine，学生基本掌握了一般疑问句的问答和mine， her....
