Your genetic makeup plays a big part in determining your size and weight. If both your parents are tall, there is a good chance you’ll be tall. But if your parents are smaller than average, you may want to rethink that professional basketball career!

The same goes for your body type. Have you ever heard someone say a person is “big boned?” It’s a way of saying the person has a large frame, or skeleton(骨骼). Big bones usually weigh more than small bones. That’s why it’s possible for two kids with the same height, but different weight, to both the right weight.

Being overweight can run in someone’s family, but it may not be because of their genes. Poor eating and exercise habits also run in families and these may be the reasons the members of a family are overweight. And even though some kids gain weight more easily than others, when they eat right and exercise, most kids can have a healthy weight that’s right for them. It’s true- the way you live can change the way you look.

How much your weight is a balance between the calories you eat and the calories you use. If you eat more calories than your body needs to use, you will gain too much weight. If you spend you free time watching TV, your body won’t use as many calories as it would if you played basketball, skated, or went for a walk. But if you eat more and exercise less, you may become overweight. On the other hand, if you eat less and exercise more, you may lose weight.

B.they must be of the same size

C.they must be of the same weight

A.Eating right and exercise normally can keep you healthy.

B.The members of a rich family must be overweight.

C.The way you live has nothing to do with the way you look.

D.the members of a poor family can’t be overweight.小题5: ______ can help you to get your weight right.

C.Eating less and doing more exercises
