The computer is fast, and never makes a mistake, while people are too 1 and full of mistakes sometimes. That's what people often say when they talk about computers. For over a quarter of a century, scientists have been 2 better and better computers. Now a computer can do a lot of everyday 3 wonderfully. It is 4 used in factories, hospitals, post offices and airports. A computer can report, decide and control in almost every field. Many computer scientists are thinking of making the computer “think” like a man. With the 5 of a person, a computer can draw pictures, write music, talk with people, 6 chess, recognize voices, translate languages and so on. Perhaps computers will one day really think and feel. Do you think the people will be 7 when they find that the computer is too clever to listen to and serve the people? No, people will make 8 use of the computers in the future. Man is always the master of the computer. The computer 9 only with the help of man. It cannot take the 10 of man.
It is reported that some developed countries have shipped broken parts of computers to China. Such a thing can be found almost every day although it is against international laws. Hong Kong officers once found 131, 000 kilograms of broken computers, TVs and phones sent from Japan.
Things like these are called electronic waste or e-waste. Dealing with e-waste is not an easy job because dangerous poisons like mercury(汞)and lead(铅)can be found in e-waste. Every time an old computer breaks down, it needs to be dealt with safely. But at present, broken computer parts are usually buried. It may be hundreds of years before they are really gone in the earth.
Many places in China are polluted by e-waste. Guiyu in Guangdong Province is one of them. This town is named as" the e-waste capital of the world”. It has to deal with 1. 5 million kilograms of e-waste each year, from which it makes 75 million yuan. But it comes at a cost. Many of the poisons in e-waste find their way into the environment. Plastic is burned outdoors and chemical water is poured into rivers. An environmental group has found the air, the earth and the rivers in Guiyu badly polluted.
The Chinese government wants to develop, but in a way that doesn't do harm to the environment and people's life. China passed a new environmental protection law in 2015, the strictest one we have ever ha D. Computer companies like Lenovo and Dell will be asked to take back their old computers. This is because the companies that make computers know how to deal with them safely. Hopefully, the problem with e-waste will be solved in the near future.
