Dear Donna, Help! I’m a 15—year—old high school student in New York, In eight months, I’m going to take an entrance exam. To prepare, I’m studying six hours a day. I want to do well, but I’m really stressed(焦虑不安的) these days. I can’t sleep. What can I do? Yours, Mary

Dear Mary, Many students around the world have the same problems as you. Here is some advice to help you deal with the street. Good luck! 1.Make a study plan for yourself, but don’t study too much in one day. You remember more by studying one hour each day for six days, than six hours in one day. Also, don’t study late at night. 2.Have a rest for 15 to 20 minutes every two hours. Go outside and walk. Doing exercise is a great way to reduce stress. 3.Don’t eat for drink a lot of sugar or drink a lot of coffee. Eat food high in vitamin(维生素) B (for example, eggs, milk, green vegetable and rice). These give you energy and help you think more clearly. 4.A student partner can help you practice for the test. When you’re worried about the exam, you can talk to your partner. This can reduce stress, too. Yours, Donna
