Today, people want to keep healthy through sports and exercise（锻炼）. But some of them have some wrong ideas about it.

“Meat is a good meal before games because it has much energy（能量）.” You can have some food like potatoes, bread, bananas and so on. But meat is not a good meal before games, Because the best food before games should have carbohydrates（碳水化合物）.

“The best time to exercise is early in the morning.” Morning is a good time to exercise, but it may not be good for you. You can also exercise in the afternoon or evening. So there is no fixed time for you to exercise.

“You can't drink water when you exercise, because it makes you feel tired.” When you exercise, you must have some water during breaks（休息时间）. And after exercising, you must have much water. If you don't drink enough water, then you may feel tired.

“______________________” No. You need to give your body a day to have a break. Too much exercise is bad for our health. And remember, don't exercise when you are very tired.

You may not have heard the words “freshman fifteen” before, but they are very important for students who are entering university. A freshman is a first-year college student. “Fifteen” refers to fifteen pounds—the fifteen pounds added to a student's weight in his or her first year. There are a number of reasons why first-year university students gain weight; but it's encouraging to know that freshmen don't have to add these harmful fifteen pounds.

University kitchens serve many kinds of food. Some students choose unhealthy food, because now their parents are not nearby to help them choose. Some students visit the kitchen many times while studying. Late at night, some students get harmful fast food such as French fries with coke to drink. Students also have less time for walking, running, and doing sports because of their schoolwork.

If you' re careful, you don't have to add fifteen pounds. Here are some ideas:

Remember that the “freshman fifteen” can happen to anyone. Talk to your friends about it. Together, try to eat healthy food and not to eat junk food. Walk, run, do sports—move and you will feel better! And it is always more fun with friends. Help each other and you can have a healthy and happy freshman year.
