答案：One possible version: Now， many middle school students face some problems. Many students have too much homework to do. To finish it， they have to stay up late. So they often feel tired and have no spare time for their hobbies. Some students feel lonely because their parents are too busy to stay with them and they don't have any close friends to talk to. I think they can talk to their parents and teachers about their problems and ask them for help. Some other students aren't happy with their weight. To lose weight and keep fit， they need to do more exercise and eat healthy food.
