My life has changed a lot in the past three years. Especially with the growth of my knowledge, I have greatly changed. I can well remember that I used to be short, but now I am one of the tallest in my class and to my joy, I have be chosen to be on the school team. Besides, what interested most in the past was playing computer games, but now I realize it is a waste of time. Reading is my favorite hobby. Good books are the key to one’s wit and the treasure in one life. Another change is that now I like vegetables and fruit much better than junk food. So you see, I am much healthier than before. All in all, I am happy with these changes because they have brought me the happiness of growth.
试题分析：这是一篇给材料作文，描述自己现在和过去的变化。本题没有给出具体材料, 只给出了几个方面，需要自己先确定写作内容,然后在动笔写作.选取材料时,注意选择自己熟悉的内容.在写作时要注意时态，结合所给材料可知，描写自己过去时，应该主要用一般过去时，描写自己现在时，应该主要用一般现在时。写作中应适当使用连词，做到上下文联系紧密，符合逻辑关系。
【亮点说明】如果文章中使用了非常好的短语或句子会给文章增色，如Especially with the growth of my knowledge；I am happy with these changes。句中使用了what，because 及that引导的从句，还运用了but ，Besides，All in all等使上下文衔接的更好。
