    December 21 was Becky's fourteenth birthday. When she got home after school, she saw her parents in the living room. They said to her, "Happy birthday, dear! We have a present for you, Becky. Go and look for it in your bedroom."

    Becky ran quickly to her room. On her bed she saw a bright red box. She thought that her present must be in the box. She opened it. There was nothing but a card in it. The girl took it out and read.

    "Dear Becky, I'm your present. My first three letters are the same as in the word 'come'. My last two letters are the same as in the word 'water'. My middle three letters are in the word 'put'. What am I?"

    Becky thought hard and soon smiled. She then went back to the living room and shouted. "Aha, I know what present it is. Thank you very much, Mum and Dad! But where is it?" Her mother answered, "Look at the back of the card." Becky turned it over and read, "Come and look for me in the study."

    Becky hurried to the study. There on the desk she found her present. What was it? Do you know?

    August has always been difficult for me. It is the time when I realize that the books my English teacher assigned(布置) to me are not going to read themselves and that I have a difficult month in front of me.

    You might think that I don't want to spend my summer reading, hut that's not the problem；I love reading. On the first day of summer holiday this year, I borrowed a Gathering of Old Men by African-American writer Ernest Gaines. I enjoyed it very much. I read all the magazines that my parents subscribe to(订阅) and spend about     minutes every day with the morning newspaper.

    So why do I hate summer reading for school？Because the books on summer reading lists are often slow-going and just uninviting(不吸引人的) . Teachers don't under-stand that summer reading can be interesting as well as educational. They choose books called "spinach books": good for you, but not much fun to take in. Every summer, I read them, hate them and get bitter about the experience.

    This bitterness started three years ago when 1 began high school. As preparation. my English teacher told me to read The Age of Innocence(《纯真年代》). At 14, I couldn't understand the love 100 years ago in the story. I only know my love for baseball. The Age of Innocence was completely different to my life. What is more, sometimes I guess teachers don't think exciting plots make for "good literature". To me, a good writer describes events and characters in a way that makes the reader want to know what happens next.

    If I were making up a summer reading list, it would include The Friends of Eddie Coyle by George V. Higgins. The Right Stuff by Tom Wolfe, and Into Thin Air by Jon Krakauer. These are all books that have literary value(文学价值) and can also entertain kids. If the teachers could add a little fun into the books they assign, my Augusts would be a lot more enjoyable.
