    At school many things happen to us. We may feel excited when we have success in a school play. We

may feel sorry if we lose an important game. We want to keep the memory for the rest of our lives.

    How to keep the memory? Our English teacher, Miss Wang, has taught us a good way of remembering

things to make our own yearbook. What is a yearbook? A yearbook is a kind of book which is used to keep

the memory of exciting moments. It's usually made at the end of the year.

    Last December, we began to make our yearbook. First we chose the persons who had done something

special, then some students interviewed (采访) them, some wrote down their stories, others took photos

of them. Everyone in our class had something to do. Finally our teacher helped us to put the things together.

We had our first yearbook.

    All of us put a lot of love into making the yearbook. It is so wonderful that not only the students but also

our parents and teachers will remember the special time for ever.
