D. Want their guests to use more disposable things.

Many disposable things are made of plastic. People throw them away after only using them once. It is a waste of natural resources and is very bad for the environment. Do you know, one Chinese person makes as much as 400kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw away about 19,000 tons of plastic bags and 1,320 tons of plastic lunch bowls every year! Plastic can take between 100 and 400 years to break down. So the less plastic we throw out, the better. So, wherever you travel, bring your own things and use them again and again.

Back at home and school, you can also do something to make our world a better place. Try to do these things in your daily life: Use cloth shopping bags, not plastic ones. After using a plastic bag, wash it out and let it dry. Then you can use it over and over again. Do not use paper cups. At your school canteen(食堂), use your own bowl and chopsticks instead of disposable ones.

Starting from June, some hotels in Beijing will no longer provide guests with these disposables. They want to ask people to use less disposable things.

On Oct. 12, 1989, some Chinese scientists were working at the computers to look for the information they needed. Suddenly they saw a lot of very bright spots crossing the computer's screens. At the same time the computers were working much slower. To find out what was happening, they stopped their work to check some parts of the computers. To their horror, they found out that most of their stored information was got rid of by computer viruses. Obviously all these computers had been infected by computer viruses.

It is said that the computer viruses were made by a group of young men fond of playing tricks. They all had excellent education. They created the viruses just to show their intelligence. This kind of computer viruses are named Jerusalem Viruses. These viruses can stay in computers for a long time. When the time comes they will attack the computers by lowering the functions, damaging normal programs or even getting rid of all the information.

We now know that Jerusalem Viruses often attack computers on Fridays and that they are spreading to a lot of computers. Among the computers that suffered from computer viruses last year are Britain, Australia, Switzerland and the US. But till now, how to get rid of the terrible viruses remains a problem.
