5 教学过程
活动1【导入】Step1 Free talk

S1:

T: They are waste, but they can be useful things again.
(比赛能调动学生的上课积极性，而欣赏与话题有关的图片可以让学生有话可讲，并能自然地进入话题。)
活动2【活动】Step2 Lead in
T: For example, what are they?
Ss: They are bottles.
T: Yes, they are empty bottles. What do you usually do with the empty bottles?
S: I usually throw the empty bottles away.
T: But from the pictures, we know some people put them to good use. They can be put to good use. Look! This is a beautiful art work/ piece.
（以其中一张空瓶子被制成的图片作为切入点，引出bottle, throw away, put
sth. to good use, beautiful art work/ piece等词汇。）
活动3【活动】Step3 Predicting
T: Not only the bottles, but some other things in our life can also be put to good use. What’s that?
Ss: It’s a house.
T: What do you think of it?
Ss: I think it’s special. …
T：They are made of things that are not wanted anymore. So don’t always throw away things that can be put to good use. We should rethink, reuse, recycle. They all have the letters re. If the letters are added in front of words, we call them prefixes.
T: Now you know the pictures and the title quite well. Can you predict what the passage is about?
