     阅读下面的短文,请根据短文后的要求答题(请注意问题后的词数要求)。

     There's a lot of discussion these days about fit kids. Being fit is a

way of saying a personeats well, gets a lot of physical activity (exercise) ,

and has ahealthy weight. If you're fit, your body works well, feelsgood,

and can do all the things you want to do.

      Here are four rules to live by, if you're a kid who wants tobe fit.

       1. Eat a variety of foods, especially fruits and vegetables.

      You may have a favorite food, but the best choice is to eat

a variety.If you eat different foods, you're more likely to get

the nutrients your body needs. Taste new foods and old ones

you haven't tried for a while.

         2. Drink water and milk most often.

      When you're really thirsty, cold water is the No. 1 thirst-

quencher. And there's a reason your school cafeteria offers

cartons of milk. Kids need calcium to grow strong bones, and

milk is a great source of this mineral.

         3. Listen to your body.

    What does it feel like to be full? When you're eating,

notice how your body feels and when your stomach feels

comfortably full. Sometimes, people eat too much because they

don't notice when they need to stop eating. Eating too much can

make you feel uncomfortable, and over a period of time, it can

lead to _____.

        4. Be active.

      One job you have as a kid-and it's a fun one-is that you

get to figure out which activities you like best. Not everyone

loves baseball or soccer. Maybe your passion is karate, or

kickball, or dancing. Ask your parents to help you do your

favorite activities regularly. Find ways to be active every day.
