     Xia Ming was worried about his study, so he wrote a letter to a magazine.
Dear editors,
     I'm a slow student in my class. Most of my classmates are much better than me. So I get very
stressed out. It's difficult to keep on working hard and it's really not fun. And I think although I
spend much time studying for the tests. I can't get good grades. My father gives me some help
sometimes. He tells me not to worry about it. But what do you think I should do?

Dear Xia Ming,
     Many famous people are not so good at the age like you. Edison, the famous scientist, had a
bad headache for his studies when he was a 12-year-old boy. But everyone knows that he did a
lot for the people in the world. And Newton had the same story like him. You should take it easy,
then try your best. I believe you can do better.
