    Everyone is talking about bird flu (禽流感). Yes it is a very dangerous disease that could make people very

sick. It will be a few months before we have good medicine for bird flu.

    But that doesn't mean you can't do anything to prevent it now.

    So far, all the people who have caught bird flu have been those who touched sick chickens or their droppings

(粪便). So it is a good idea for people to stay away from live chickens. "People used to (过去常常) go to the

markets to buy live chickens to eat, but now they have to change that habit," said Peter, an expert (专家) from

World Health Organization. But if you do touch a sick bird, remember to wash your hands carefully with soap

at once. Experts (专家) also say having good habits and a healthy body will help keep you safe from bird flu.

For example, don't buy or eat birds that have not been checked. Don't eat anything that has touched raw meat.

Also don't forget to open your windows often and do the sports. Getting enough sleep is also very useful for

fighting illness .If you feel sick, see a doctor right away (马上). At present (目前), no one in Shanghai has bird

flu. But WHO says children under 12 years old could easily get sick with bird flu.

    Try to stay away from people who have the flu, and always cover your mouth and nose when you cough or

sneeze.

Look into the mirror and what do you see? You see yourself. But when you move. you do everything backward(相反地)in the mirror! If you wave your left hand, your right hand waves in the mirror. If you wink your right eye, your left eye, your left eye winks(眨). Try to read a page in the mirror .The words will be backwards.

What is really happening? You do not see through the glass of a mirror as you do through a window. The glass of a mirror has a silver coating on the back. The light from the sun or a bulb bounces (弹回)off you ,goes into the mirror ,and bounces straight back out to you again.

Mirrors have been used for thousands of years. The earliest were round pieces of shiny metal. Glass mirrors came late. The ancients thought that a mirror was magic. They did not understand how it worked. They thought they saw their spirits in a mirror and breaking a mirror brought bad luck.

Today mirrors have many uses .For example, they can make rooms look bigger and prettier. They also show us if our hair is combed(梳理) well and our faces are clean. On cars, buses and trucks, mirrors help drivers see traffic behind them. Mirrors are also used in telescopes(望远镜)and searchlights(探照灯).
