It's three o'clock in the afternoon. Some girls are in the park. Linda is flying a kite with her friend, Lucy. Mary is near a river. What's she doing? She's watching fish. They are swimming in the river. Amy is behind a tall tree. She's dancing. And what is Lily doing? She's drawing a picture. They are all very happy in the park.

    Look at this room. It's nice and clean. There is a big bedroom and a big living room. In the living room, there is a sofa and a desk. There is a yellow chair in front of the desk. You can see a computer and a plant on the desk. There is an English book near the plant.

    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.
