Red Ribbon Week is held every year, usually during the last week of October. It started with a police officer named “Kiki” Camarena. He was sent to Mexico in order to investigate(调查) a Mexican drug company and stayed there for four and a half years. His efforts helped put a stop to several major drug making companies. So the bosses wanted to murder the men who brought them down. When Camarena left his office for a lunch date with his wife on February 7, 1985, a car drove up and kidnapped(绑架) him, and a month later he was killed. At that time he was only 37 years old.
Shortly after his death, people in Camarena’s town began wearing red ribbons in his honor. Then Camarena’s high school friend, Henry Lozano, started Camarena Club. Hundreds of people joined the club and promised to be drug-free in order to honor the death of Camarena. And then schools in several states began to join in. Now, at the end of every October, millions of Americans wear red ribbons in memory of “Kiki” Camarena. So, in 1988, the first national Red Ribbon Week was founded in America.
Red Ribbon Week has become the largest drug education and prevention organization in theUnited States. It encourages communities to stand up against drugs and it encourages children to make a promise not to take drugs in their life.

Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries slowly.
You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes
Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.
Your hands and wrists (手腕)
Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something. 2) Keep your elbows (肘部） at the same height as the keyboard. 3) Stop something and exercise your hands, wrists and fingers in a different way.
Your back
Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you should sit with your back straight. The top part of the screen should all be in front of your eyes. Your forearms（前臂）, wrists, hands and the upper（上部） part of your legs should all be parallel (平行) to the floor. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and necks.

Of the 90 million pet cats in this country, about two—thirds are allowed to go outside. It is said that these cats kill hundreds of millions of birds each year, as well as billions of small animals such as rabbits and field mice.
