                                                                   What should I do?

    One of the most popular items in the school newspaper is the advice column. No one knows who writes it. The students think their teacher does, but it might be a student using a false name. The students enjoy

thinking up problems for the advice column. Here are some of them and their answers.

                                                                    ASK THE WISE OWL

Q: I'm always late for school. I try not to be, but I can't help it. Please advise me what to do. Tommy.

A: You are probably late for school because you don't really like school. My advice to you is to try and

enjoy school more, then you won't be late so often.

Q: I find it difficult to make friends. What do you think I should do? Sara.

A: I can't advise you until I know more about you. Your problem may be that you are shy. On the other

hand, it may be the opposite. You may be too bold (大胆的). Write and tell me more about yourself.

Q: I'm always at the bottom (底) of the class. What do you advise me to do? Molly.

A: I advise you to concentrate on improving your grades in one subject to start with. If you can do this,

you should move a little way up from the bottom. Next, try to improve your grades in another subject, and so on. If you concentrate on one subject at a time, by the end of the year you should be quite a long way

up from the bottom in all your classes. The Wise Owl.
