Jack is a businessman. His main task is to sell “Living Machines”. He is very interested in clean water. He is also interested in saving money. So it’s natural that he is to be a developer of a small and affordable system (系统) to clean waste water. His “Living Machine” can clean waste water in your home.

The “Living Machine” is a system for cleaning waste water. The waste water goes into a big plastic tank where bacteria (细菌) start to break down the waste. A few days later after it is dealt with, the water is brought into a greenhouse filled with plants and fish. With the help of sunlight, the plants and animals remove more chemicals from the water, making it cleaner. Then the water can be reused for washing or bathing. It can’t be used for drinking and cooking. But the water is clean enough for watering the flowers, washing the dog, or even for bathing or swimming.

The advantage of this technology is that it is affordable and good for the environment. If you have enough homes and businesses use “Living Machines”, you’d better buy it. It can help to use less fresh water. It can help keep the water supply unpolluted, too.

With the rapid development of science and technology, the ways of communication among people have changed a lot in the past years.

As we all know, in ancient times, people communicated with others who were far away only by writing letters. It took a very long time to get the message.

In the 19th century, telegraph was invented, but it was not widely used. The letter was still the commonest way at that time. In 1836, John Coker invented the first electromagnetic telegraph (电磁电报机) in the world, and then telegraph came into being and was popular. It was much faster than letters, bringing great convenience to people.

As time goes by, telephones become increasingly widely used. Now, phones have been developed as mobile phones, fixed telephones, Internet telephones and other categories. They are important communication tools in modern information society.

In addition, network communication is popular as well. It is especially widely welcomed by the youth. A great number of people communicate with others on the Internet by using software (软件), such as QQ, Wechat, BBS and MMS. Using software is easy. A computer which is connected to the network is enough. In China, Wechat has become the most popular communication software nowadays. Wechat, known as Weixin in China, is a mobile phone text and voice messaging communication software which is developed by Tencent. People who make video calls can not only hear the sound, but also see the people they talk to.
