七、任务型阅读。
阅读短文，回答下列问题。
We all know teeth are important to us. We celebrate Love Teeth 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 any smarter. They are seen as a symbol of being grown-ups.
Do you know how to keep your teeth strong and healthy? Let's look at the following tips.
What you 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 dental floss(牙线) for your teeth to make them cleaner. Get a new toothbrush every three months.
What you 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.
注：每题答案不超过6个词。
1. When do we celebrate Love Teeth Day?
2. How many baby teeth do children under 6 years old have?
3. Why do we need to use dental floss?
4. How often should we get a new toothbrush?
5. How do you keep your teeth healthy in your daily life?（请自拟一句话作答）
