    Hello! I'm John. I'm ten. I'm from Shenzhen, China. I'm short and fat. I have a big head and a big body. I have two small eyes and a big mouth. I have two long arms and two short legs. My feet are small. My hands are small, too.

    We get headaches sometimes. But how much do you know about headaches? What may cause that? And what should we do if we have a headache? When should we go to see a doctor?

    A headache is not a disease, but it may show that something in our body is wrong. We may have more than one headache each month.

    Usually a fever may cause headaches. We may get a headache when we work too hard. We may get a headache when we don't get enough sleep. We may get a headache when we exercise with an empty stomach. What should we do if we have a headache?

    We should lie down and rest. We should have a good sleep. We shouldn't take too much exercise if we are hungry. If we have headaches often, we need to see a doctor.

Mary: What can you do at home, Lisa?

Lisa: I can clean the windows and make the bed. What about you, Tom?

Tom: I can cook the meal and water the flowers. Can you sweep the floor?

Lisa: Yes, of course. I often help my mom sweep the floor.

Mary: No, I can't. But I can do the dishes and wash the clothes.

Tom: We are all helpful at home.
