First,haze does harm to our physical health in an unclear way.When we draw air into our lungs,we breathe haze as well.So the respiratory(呼吸的)system may not be able to work well.Second,haze causes reduced visibility and this contributes to traffic st but not least,haze leaves a negative impression of the city.As a result,cities that are suffering from haze will look less attractive. Since we have known the reasons and the bad effects of haze now,we have to take action to solve the problem and make our city an agreeable place to live.

日前,一幅北极冰盖融化时的照片发人深省,因为它看起来仿佛一 张“哭泣的人脸”,专家形容这就像是绝望的“大自然母亲”在对全球变暖 的世界环境进行无声的抗议。
Arctic ice reveals last decade was the hottest in 2,000 years. The Arctic is now warmer than at any time during the last 2,000 years,according to a major new study. Temperatures around the North Pole have dramatically increased in the last 50 years—reversing a long-term natural cooling trend,scientists say.
The decade between 1999 to 2008 was the warmest in the last 2,000 years,the research found. Previous research has shown that Arctic temperatures rose three times faster during the 20th century than the rest of the Northern Hemisphere. Some experts have predicted that the Arctic could be free from sea ice in the winter within the next few decades if the temperatures continue to rise.
