Xiao Ming’s Letter and the Answers Xiao 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?
