In most parts of the world, many students help their school make less pollution. They join in “environment clubs”. In an environment club, people work together to make our environment clean.
Here are things students often do:
Turn off the water! Do you know that some toilets can waste twenty to
forty tons of water an hour? In a year, that would fill a small water! In environment clubs, students mend those broken toilets.
No-car day. On a no-car day, nobody comes to school in a car-not the students and not the teachers. Cars give pollution to our air, so remember: walk, jump, bike or run.
Use your legs! It’s lots of fun!
No-garbage(垃圾) lunches. How much do you throw away after lunch?
Environment clubs ask students to bring their lunches in bags that can be used
again. Every week they will choose the classes that make the least garbage
and report them to the whole school.
We love our environment! Let’s work together to make it clean!

● Brush your teeth the right way.
Brush your teeth at least twice a day after breakfast and before bedtime. If you can, brush after lunch or after sweet snacks(快餐), too.
Brush all your teeth, not just the front ones. Spend time brushing teeth along the sides and back of your mouth. Brush away from your gums(齿龈), too.
Spend at least three minutes each time you brush. Play a song you like to help pass the time.
Get a new toothbrush every three months. When you buy your tooth brush, be sure it has soft bristles(鬃毛).
● Learn how to floss your teeth.
Flossing is a very important way to keep your teeth healthy. Food may hide in places where a toothbrush cannot get to, like the space between the teeth. Flossing can help get rid of it. Carefully move the floss between two teeth, up and down. You need to floss your teeth at least once a day.
● Have good eating habits.
You need to be careful about what you eat and drink. Eating sugar is a major cause of tooth decay(腐朽). Eating sugar before you go to bed can make things even worse. Eat lots of fruit and vegetables and drink water instead of soda.
