阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项。
A
Our bodies need a healthy diet which should include all the things you need to develop normally—proteins,carbohydrates,fats,minerals and vitamins.Cutting out things you might see as fattening,such as carbohydrates or fats,can stop your body from developing normally.
There are some simple rules which can help you to stay a healthy and normal weight.They sound quite easy but might be more difficult to put into practice.You can ask your family and friends to help you to stick to these rules—and it might even help them to be a bit healthier!
·Eat regular meals—breakfast,lunch and dinner.
·Include carbohydrate foods such as bread,potatoes,rice or pasta with every meal.
·Eat at roughly the same time each day.Long gaps between meals can make you so hungry that,when you do eventually eat,you eat far more than you need.
·Get enough sleep.
·Avoid sugary or high fat foods and junk foods.If you have a lunch of crisps,chocolate and a soft drink,it doesn’t feel as if you’re eating very much,but it will pile on the pounds.A sandwich or roll with fruit and milk or juice will make you feel fuller,but you are much less likely to put on weight—and it’s better for your skin.
If you follow these suggestions you will find it easier to control your weight,and you won’t find yourself wanting sweet foods all the time.
