    When I was ten years old, my father got very sick. He couldn't walk well, but he swent to school with me. He said, "It's my duty to tyou to school. I want to see you every minute." The day before he died, he told me to go to university no matter how pwe were. I really miss him and I haven't for gotten his words. Now I live with my aunt. I can't go to middle school b I don t have enough money. I help my aunt sell things in the market. This is what I say every day, "Biscuits. 3 dollars." I will try my best to earn some money to realize my father's d.

    One day, a rich man met Tom. The rich man asked him, "I heard you are very clever and nothing is difficult fyou. Can you tell me wyou are so clever?"

    Tom answered with a smile on his face, "Oh, I am not clever. Maybe it is be-cause you are too foolish." The rich man became very angry, of course.

    Tom said, "Please dbe angry with me. If you don't believe what I said, now let me ask you a very simple question; If you have a group of sheep, I gyou another group. Then, tell me, how mgroups of sheep do you have? " "Oh That's the easiest question in the world！ One and one is two. Anybody knows that. I have two groups of sheep, of course."

    Tom laughed and laughed and said, "You are quite w, I'm afraid. Two groups of sheep put together is still ogroup. That's the easiest question in the world, isn't it?"
