Jenny: That’s a lot of garbage! Can I help you sort it
Danny: Yes, please. Let’s put the glass here, the metal here, the plastic here and the paper here.
(After they sort the garbage, Danny and Jenny are surprised. Almost all of it can be reused or recycled! They need to throw away only one small bag of garbage!)
Text
Jenny: People throw too much away. They shouldn’t waste so much!
Danny: That’s right. Look! There is more paper than plastic. And there is less metal than plastic. There is the least amount of glass.
Jenny: And the most amount is paper. It is a waste to use paper only on one side.
Text
Danny: Hey! I found a toy car. One of the wheels is broken. I’ll take this car home and clean it. Then I’ll use some glue to fix the broken wheel. When I finish fixing this car, I will give it to my little cousin, Debbie.
Jenny: Nobody should throw away a toy like this. It can be fixed. It’s not right to waste things. Look at all of the glass. It can all be recycled and made into new glass.
Text
Danny: A lot of glass is broken. It’s dangerous to leave broken glass on the ground. Once, I cut my foot on a piece of broken glass.
Jenny: Litter can hurt people!

【拓展】empty的不同词性

a sort of 一种 all sorts of 各种各样的
e.g. The students think of all sorts of ways to solve

学生们想到各种各样的方式解决这个问题。
2. Can I help you sort it
(1) 此句为含有情态动词的被动语态，其构成形式为：情态动词(can/may/must/should)+be+过去分词
e.g. The flowers should be watered every day.
花应该每天被浇。
Cars mustn’t be parked here.
汽车不应该被停在这里。
3. Almost all of it can be reused or recycled!
(2) re-是前缀，意思是“再，重新”，
如rewrite, replay, reappear, rebuild, remarry等。
reuse 重新使用，再使用
e.g. She often reuses the packaging.
她经常重新使用包装。
recycle 使再循环；使……重新利用，重复利用
e.g.
They recycle empty cans in order to reuse the metal.
为了重新利用金属，他们循环使用空的易拉罐。
辨析：too much, much too和too many
too much 修饰不可数名词或修饰比较级，有“过分，难以接受”之意。
too many 太多，修饰可数名词的复数 。
much too 太……，修饰原级。
4. People throw too much away!
e.g.

在中国的南方雨水很多。
I see too many presents in the room.

5. There is the least amount of glass.
can be done是含有情态动词的被动语态。
fix相当于mend和repair，意思是“修理，修补”，
但fix较为口语化。mend除可以表示一般性修理外，还可以用来表示对衣服等进行修改或修补。
e.g. Can you fix the broken car
你能修理一下这辆坏了的车吗？
