Question: why do the little blackbirds fly away?
引导学生用Unit6 所学知识回答：
Because the air is dirty.
Because there aren’t any trees on the hill. They have no
home.
T: Now our living environment is polluted, so we should
protect the Earth.——出示课题并教读。We
should make the Earth a better place for you and me, and the entire human race.

Step 2. Pre-reading
1.出示无污染的地球图片。
T：Look, the
Earth is a beautiful place. There are many kinds of sources in it. Do you know
some of them? ( water, trees, air etc.)

① It’s black and hard. We can
find it under the ground. It can make us warm. There’s a lot of it in Shanxi. (
coal )
② It’s a black liquid. We can
find it under the ground too. Cars need it. ( oil )
③ It’s usually white and thin.
We can write and draw on it. ( paper )
④ It comes from trees. We use it
to make tables, desks, chairs, beds and many other things. ( wood )
