⒈An artist Tries to Solve the Smog Problem Beijing is a city often covered with smog. Many people are looking for ways to solve it. A Dutch artist has made a tower that takes in smog and gives off clean air. This tower is 7 metres tall and is the biggest air cleaner in the world, according to Chinanews.com. It can clean the air in an area the size of a soccer field in 36 hours. Beijing has been testing the tower since January. But some experts don't think this tower can truly work. "It's more of an art piece to raise people's awareness(意识) of air protection," they said. People will know if the tower works when the results come out. Teens |

⒉The World's Worst Traffic If we travel in big cities, it's very likely that we will come across traffic jams, which often make us complain. But people in Bangkok, Thailand, have more to complain about. This is because Bangkok has the worst evening rush hour traffic in the world, according to a GPS company in Europe. Each year, the company will work out a list of the world's most congested(拥堵的) cities. The results are based on statistics(数据) of 390 cities across the world. This year, Chinese cities Chongqing and Zhuhai are also on the list. The list aims to help drivers and cities understand the traffic trends (趋势) and take action to improve the bad traffic. Teens |
