七、阅读表达。
阅读短文，回答下列问题。每题答案不超过5个词。
We all know teeth are important for our lives. We celebrate National Teeth-Loving Day on 20 September.
Do you know the life cycle of the teeth in your mouth? Children under 6 years old have 20 baby teeth. From 6 to 13, people lose their baby teeth one by one. Now permanent teeth(恒牙) begin to grow. Between the ages of 17 and 25, some people grow wisdom teeth(智齿). Of course, wisdom teeth don't make you smarter. They look like a symbol(象征) of being grown-ups.
Do you know how to keep our teeth strong and healthy? Let's look at the following tips.
What we can do
Brush your teeth at least twice a day: in the morning and before bedtime. Brush for at least two or three minutes every time.
Brush up and down on every tooth.
Use a dental floss(牙线) for your teeth to make them cleaner. Get a new toothbrush every three months.
What we can’t do
Don’t eat too much candy or sweet food. Don’t drink too much soda. Don’t eat very hard food that can hurt your teeth.
Don’t eat snacks before bedtime.
Teeth are important to everyone. Healthy teeth help us eat food to let us grow. They help us speak clearly. And yes, they help us look good.
