    I was reading an article in a book while I came across a word I didn't know. “Dad, what is the meaning of the word?” My dad, as he usual did after work, was watching his most favorite show. “You have the dictionary, don't you?” he shot back. He didn't even look up my face. I went back my room, and there on my study table is that dictionary. I looked it up and found it's exact meaning. Ten year have passed and I still use that dictionary, along with the lesson I received earlier in life from my old man: to be independent.

按要求修改。
咱家那些事
      咱家是个四口之家，除了我，每个人都颇具个性。
      家有贪玩而智慧的爸爸。爸爸的工作是跑业务，经常一连几天都看不到他。爸爸在家时，最爱上网“斗地主”。电脑一开，爸爸就激情澎湃地“战斗”了。
      最让咱家感到幸福的是妈妈。（下面写“妈妈烧得一手好菜，自创菜谱”来表现贤惠。）
      我家还有一宝，就是我的妹妹。（下面写妹妹自导自演一出“话剧”，突出聪明可爱。）
      看到这里，你一定会觉得我有一个和谐快乐的家。
