(通过复习颜色单词，并比较，引出课文。)

反义词示例：new-----old small-----big thin-----fat tall-----short(long)

Step2、lead-in

T：Yesterday I bought a new bag. My bag is broken.（新单词broken）Guess, what color is it? What color is your bag?

教师拿出两个提前准备好的包进行描述:

1. This is my bag. It's green. But it is old and broken.(拿一个破旧的包进行描述;实物能够让学生充分理解broken的意思)

2.然后拿出一个新的包:This is my bag too. It's red. It's new. It's got two pockets.(出示pocket这个单词,并指着包上的口袋让学生明白其意思.)

3. Let SS carry the two bags. Ask how they feel. (自己可先做示范，教授新单词：heavy，light)

There are three books in my new bag, so it's heavy.

There is nothing in my old bag, so it's light.

4.将新学的单词编成一首chant,便于学生记忆:

Pocket, pocket, pocket,

My bag has one pocket,

Light, Light, Light,

Her bag is Light.

Broken, broken, broken,

Your bag is broken.

Heavy, heavy, heavy

His bag is heavy.
