Many students don't realize how daily habits affect their health.
Eating too much 46 (
unhealthy
) food can make us feel tired. They don't give our bodies the energy we need to study and play but make us fat. A big problem with sweet foods and drinks is what they do to our 47 (
teeth
). Dentists (牙科医生) say we should brush them 48 (
twice
) a day to keep our smiles shining.
Another important health rule is getting enough sleep. Teenagers usually have 49 (
less
) than 8 hours of sleep each night. They like to stay 50
up
to play games or read novels. Doctors say we 51 (
really
) need 8 to 10 hours to make ourselves feel good.
There are many simple 52 (
ways
) to stay healthy. Eating three 53 (
meals
) regularly with fruit and vegetables, drinking more water instead of 54 (
bottles
) of coke, and 55 (
playing
) outside to have a rest are all good ideas. When we take care of our bodies, we have more energy to enjoy life and do well in school!
