    As we know, when senior students finish their school, most of their reference books are thrown away, which are still in good condition. How a great waste it is!

    I suggest that students must recycle all these books. On the one hand, recycling them can save a lot of natural resource, which are used to make textbooks. On the other hand, the notes in the books are helpful to whoever need them.

    In fact, recycling textbooks has been increasing popular in such countries like America and Australia. We should learn from them, but make every effort to build energy-saving society. In my opinion, it is of much benefit from our present and our future.

    I went to see the film after supper. On my way to the cinema I met an English woman, that had lost her way. I gave up the chance see the film and take her to her hotel. While go there, I told her about great changes that had taken place here in the past few years and she told me something about her country. Although I missed the film, but I still felt very happily.

    My friend Mike have benefited greatly from humor. He is kind but overweight, that brings him a lot of problems. Once one of my classmates laughed him,“ Why are you so fat?” We all stopped to stare at Mike, wonder how he would answer the question. She just said in a calm voice, “Well, because of my size must be large enough to hold my large heart of love.” Hearing his word, we all burst into laughter.

    Watching one of the flag-raising ceremony in the capital left me a deep impression. On the morning of January 1, 2018，my parents and I go to the Tian'anmen Square. When they got there, a lot of people were already waiting. See the soldiers walking in sight, all of us felt exciting. Pacing in order, and the soldiers came to the stand. Then the mostly exciting moment came. The flag rose little by little with the familiar music, and we sang by it. The flag reached the top the moment the music came to end. Just then, cheers burst out from the crowds, what made me proud of our motherland.
