阅读理解。 You may have known several kinds of police, traffic police, and street police. But have you ever heard of energy-saving (节能) policemen? A group of 22 of these new policemen went to work last week in Beijing. They go around the city to see the use of energy in hotels, office buildings, shopping centers and onther public places. One of their aims is to make sure that these sites have set their air conditioning (空调) no cooler than 26 ℃. They also set up a special phone line so that people can tell them which buildings fail to follow the rule. 'If everyone sets their air conditioning at 26 ℃, Beijing will save 400 million kilowatt-hours of electricity in one summer. That's one-third of all the usage of the city in the season,' said a TV advertisement. Other Chinese cities, like Wuhan in Hubei Province and Yangzhou in Jiangsu Province, are going to follow Beijing's steps in setting up a similar police team. As one of the fastest developing countries, China is using a lot of energy. This has a great effect on the country's environment and limited energy. From 1986 to 2005, the country experienced 20 warm winters continuously. Numbers show that Chinese cities have to spend billion of yuan solving (解决) environmental problems every year. At the beginning of this month, China made its first action plan to fight pollution. It aims to reduce energy usage by 20％ and increase renewable energy up to 10％ from 7％ by 2010. To introduce the public to a green life, last week Beijing held a show on energy-saving technology and productions. Environment-friendly machines, such as a vending machine that helps colllect used bottles, have attracted lots of attention. 'We want to tell people that there are certain ways to protect the environment. Each of us can find effective ways to do it in our daily lives,' said Liu Qianguang, an environmental engineer in Beijing. 1. The job of the energy-saving policemen is ___________.
