Dear fellow students，

【答案】Dear fellow students，
    I'm writing to you. Here is my suggestion that we recycle textbooks.
    There are many reasons why we should do this. Above all， a large number of textbooks have been used， resulting in a serious waste of resources. For another， recycling textbooks can release the financial burden of society and individuals.
    However， what should we do to recycle textbooks？ On the one hand， the careful usage of textbooks is needed， which will guarantee they can be used again. On the other hand， we should set up an institution to organize the textbooks recycling.
    Finally， I propose that we all take action to participate in the activity of recycling textbooks and contribute our own strength to save resources.
Yours，
Li Hua
