Ⅴ．Focus Explanation and Practice:
In order to help the students understand the dialogue correctly and master the mastery contents, according to their study, I'll explain and practice some of the following language points:
1．Jenny has emptied two bags of garbage onto the floor.
empty 可作形容词或动词，意思是“空的；倒空”。
E.g.: There is an empty bottle on the table.
Can you empty the plates for me
2．Can I help you sort it
（1）提供帮助常用句式： Can I help you / What can I do for you
答语： Yes, please. / No, thanks.
（2）sort 可作名词或动词，意思是“类；分类”。
E.g.: What sort of people are they
We must sort out the bad apples from the good.
3．That's everything that isn't glass, metal, plastic or paper.
that isn't glass, metal, plastic or paper是定语从句，用来修饰先行词everything，关系代词只能用that，不能用which。
4．Good heavens! So much garbage!
good heavens意思是“天哪”，表示惊讶，不相信等。
5．That's the same weight as a small car!
（1）the same…as意思是“和……一样”。 same前必须加the. For example:
They have the same population （人口） as we do.
