Question

【题目】任务型阅读

Everyone has two sets of teeth. The first set (of twenty) begins to grow when you are over six months old. The second set (of thirty-two) grows from the age of six until(直到) you are about twenty-one years old.

To help your teeth grow strong, you must drink much milk and eat green vegetables. Then your body will have the right chemicals(化学物质) that build teeth.

You should brush your teeth after each meal. You should turn the brush and go up and down as well as brushing sideways. If you can't brush your teeth after eating, rinse(冲洗) them with water, or eat an apple or a carrot.

Try to visit a dentist every six months. If there is a hole in the teeth, the dentist will fill it. If you do not have it filled, then the hole will grow larger. When a hole grows too big, the tooth may have to be taken out. So you should take care of your teeth well.
