( )1. Dear Molly,

     I have a problem. My parents are always talking to me about studying. They want me to study harder

so I can go to a good school. I know studying is very important, but my parents put too much pressure

on me. How can I explain to my parents that I need some free time?

( )2. Dear Molly,

     My best friend Tony is a nice young man, but he has a bad habit. He is always late. No matter where

he is going to what he is doing, he is never on time. Once he turned up thirty minutes late for a meeting!

What can I do to break him of this bad habit?

( )3. Dear Molly,

     I have a new roommate named Louis. He is a good friend of mine, but he is driving me crazy because

What can I do?

( )4. Dear Molly,

     My cousin plays computer games a lot and he keeps on talking to me about various games. I don't have

any interest at all, but I find it difficult to stop him without hurting his feelings. Would you kindly give me

some advice?

( )5. Dear Molly,

     I'm feeling upset these days because the result of my last English exam was not as good as I had expected. My teacher comforted me, saying "Don't worry. You can do better next time." But I'm still feeling bad. I need

your help.
