Dear mom,
I’m writing to you from America. You don’t know how happy I am. I made many new friends here. They are very helpful. Last week I got a fever and had to stay in bed for three days. They helped me a lot with my lessons. Cathy is one of my good friends at school. She has a round face with a pair of glasses. She is two months older than I am, but a little shorter . She works hard and is good at all her lessons. She often helps me with my English. We like talking to each other at lunchtime. After school, we always go home together because we live in the same street.
Sometimes we take a dancing lesson for half an hour before we go home. She dances better than any other student. She wants to be a dancer when she grows up. At the weekends, Cathy usually goes swimming. I sometimes go swimming with her. I think it’s a good way to keep healthy. We always have a good time.
Write soon.
Love

Some people think only school children do not agree with their parents. However，it is not true. Communication（交流）is a problem for parents and children of all ages. If it's hard for you to communicate with your parents，don't worry about it. Here is some advice about getting on well with parents.
Don't argue（争辩）with your parents. Don't talk with your parents when you are angry. Your parents probably won't think over your ideas if you are shouting at them. And you can't express yourself well if you are angry. Go some place to cool off and think about what you want to say to your parents.
Try to reach an agreement. Perhaps you and your parents disagree on something. You can keep your disagreement and try your best to accept each other. Sometimes your parents might refuse to accept your reasons for something. In these situations, it is especially important to show love and respect to them. Showing respect will keep your relationship strong.
Talk about your values （价值观）. The values of your parents are probably different from yours. Tell your parents what you care about, and why. Understanding your values might help them see your purposes in life.
A good relationship with your parents can make you a better and happier person. It is worth having a try! Is communication a problem only for parents and school children?
How many pieces of advice does the writer give you?
What should you do when your parents refuse to accept your reasons?
Why do you need to talk about your values with your parents?
