写作题

读写任务。

阅读下面的短文,然后按照要求写一篇150词左右的英语短文。

This weekend in Sydney, Australia “lights out” activity will be staged. Sydney people will keep lights off for an hour, so that the Australia’s largest city will be thrown into darkness in the night.

In Sydney, a large number of businessmen have been added to this action plan. The government officials and tens of thousands of people have also answered the call enthusiastically.

The landscapes of Sydney such as Sydney Opera House, Sydney Harbor Bridge and dozens of skyscrapers will keep lights off for one hour from 7:30, and even McDonald’s big “M” logo will be switched off. But its significant lighting, such as the flying lights and the traffic lights will be on as usual.

This event is called “Earth Hour”. One of the organizers says this action will encourage Australians to switch off unnecessary lights in their daily life.

“Our aim to do this is very simple. We do not want people to return to live in cave time. We just want to reduce greenhouse gases into the atmosphere as much as possible.” He also said, “One-hour  black out is only the beginning, and the next step is to improve people’s awareness of energy saving”.
