Problems	Solutions(解决办法)
My best friend Jack goes on vacation a lot and always brings me something expensive. I don’t have enough money to get him anything every time. What should I do? Bob	Souvenirs don’t have to cost a lot. Show him you are thinking of him. That’s important. Imagine how excited he would be if he got a postcard from you! Miller
I have a crush on a movie star. I really wish I did not. I have had dreams about him, and I even find myself wishing to be his wife. Are there any ways to stop this? Alice	A star is cute, but what else? What do you think is important for person? Being good-looking or kind-hearted? Remember that the star in the movie probably isn’t what he is like in real life. So don’t let yourself spend too much time on the star. Staying with friends or taking more activities will help you get him out of your mind. Miller
I’m always arguing with my parents. I hate it, but I can’t help it. What can I do? Harry	Sometimes it seems that our parents just don’t know us well, doesn’t it? When I’m arguing with my parents, I usually take a walk and calm myself down. It gives me time to clear my head. That means I can talk to them and solve(v.解决) the problem. Have a try—parents are easier to talk with when you are cool and calm. Miller
