Article: Some years ago industries had more freedom than they have now, and they did not need to be as careful as they must today. They did not need to worry a lot about the safety of the new products that they developed. They did not have to pay much attention to the health and safety of the people who worked for them. Often new products were dangerous for the people who used them; often conditions in the work place had very bad effects on the health of the workers. Of course sometimes there were real disasters which attracted the attention of governments and which showed the need for changes. Also scientists who were doing research into the health of workers sometimes produced information which governments could not ignore. At such times, they inquire into the causes of the disasters or the problems. New safety rules were often introduced as a result of these inquiries; however. the new rules came too late to protect the people who died or who became seriously ill. Today many governments have special departments which protect customers and workers.In the U.S, for example, there is a department which tests new airplanes and gives warnings about possible problems. It also makes the rules that aircraft producers must follow. Another department controls the foods and drugs that companies sell. A third department looks at the places where people work. and then reports any companies that are breaking the laws which protect the health and safety of workers. Of course, new government departments and new laws cannot prevent every accident or illness. but they are having some good results. Our work places are safer and cleaner than before. The planes and cars which we use for travel are better. Producers are thinking more about the safety and health of the people who buy and use their products.

Article: Handshaking, though a European practise is often seen in big cities of China. Nobody knows exactly when the practice started in Europe. It is said that long long ago in Europe when people met, they showed their unarmed hands to each other as a sign of goodwill. As time went on and trade in cities grew rapidly, people in cities began to clap each other's hands to make a deal or to reach an agreement. This practice was later changed into shaking hands among friends on meeting or leaving each other. "Let's shake (hands) on it" sometimes means agreement reached. Do the Europeans shake hands wherever they go and with whomever they meet? No. Sometimes the Chinese abroad reach out their hands too often to be polite. It is really very impolite to give your hand when the other party, especially when it is a woman, shows little interest in shaking hands with you and when the meeting does not mean anything to him or-her. Even if, for politeness, he holds out his unwilling hand in answer to your uninvited hand, just touch it slightly- There is generally a misunderstanding among the Chinese that westerners are usually open and straighforward, while the Chinese are rather reserved in manner. But in fact some people in western countries more reserved than some Chinese today. So it is a good idea to shake hands with a westerner only when he shows interest in further relations with you.
