As we know, when the students finish the middle school, they may throw away their textbooks, though most of them are still in good condition. It is really a great waste!
I suggest that we should recycle these books. ⑴ On the one hand, we can save a lot of materials by recycling them. On the other hand, the students have made plenty of useful notes on the pages, they are very helpful to the following users.
At present, the whole country is calling on us to build a saving society. ⑵It is very meaningful to our country. In fact, in other countries, recycling textbooks is also popular.
