不是仙境是污染,首都等各大城市霧霾籠罩
AIR pollution levels in Beijing have hit dangerous levels in recent days, with smog drastically reducing visibility and authorities warning people to stay indoors and avoid strenuous exercise.
北京的空氣污染水平最近幾天已經達到危險水平，霧霾大大降低了能見度，政府提醒人們呆在室內，避免劇烈運動。Local authorities said the severe pollution is likely to persist until Tuesday, as weather conditions are preventing pollutants from dispersing.
地方機構說嚴重污染可能持續到週二，隨着天氣狀況正防止污染物擴散。The Beijing Municipal Environmental Monitoring Center has reported air quality readings between 176 and 442 from its monitors throughout the greater Beijing area since Friday.
北京市環境監測中心報告了自上週五以來監控整個北京地區的空氣質量數據在176和442之間。
The monitors measure levels of airborne PM 2.5 particulates. These tiny particles are considered among the most harmful as they can travel deep into the respiratory tract, reaching the lungs. Exposure is linked to respiratory and other problems.
監測是以空氣顆粒物PM 2.5來衡量的。這些微小粒子被認爲最有害因爲他們可吸入呼吸道到達肺部。暴露其中會引發呼吸道等其他問題。Air quality is considered good when readings are 50 or below but hazardous at between 301 and 500, when people are told to avoid outdoor physical activities.
當數據PM2.5低於50時空氣質量被認爲是好的，但在301和500之間時就有危險，當人們被告知要避免戶外體育活動時。The elderly, children and those suffering from respiratory and cardiovascular diseases are advised to stay indoors to reduce exposure to polluted air.
老人、兒童和那些患有呼吸系統和心血管疾病的人建議儘量留在室內，減少接觸污染的空氣。Monitors in Beijing reported air quality indexes above 300 on Friday, and the center's real-time reports showed the capital remained heavily polluted yesterday, with readings around 500 at 5pm from some stations.
週五北京公佈的空氣質量監測指標PM2.5高於300，中心的實時報告顯示首都仍然嚴重污染，昨天下午5時一些地區的PM2.5在500左右。A warning on the monitoring center's website yesterday said the density of PM2.5 had reached 700 micrograms per cubic meter in many parts of Beijing and that the pollution was set to linger for three more days.
監控中心的網站昨日提醒說在北京的許多地方PM2.5的密度已經達到700微克每立方米，污染將持續三天。This air quality data is the worst in Beijing since the municipal government began to track PM2.5 early last year.
自北京市政府去年年初開始追蹤PM2.5以來，這是最糟糕的空氣質量數據。Sports activities stop
體育活動停止According to rules issued by the city government in December, all outdoor sports activities are to stop and factories have to reduce their production capacity if Beijing's official air quality reading goes over 500.
根據市政府在12月發佈的規定，所有戶外體育活動都叫停了，如果北京的官方空氣質量讀數超過500時工廠不得不降低他們的產能。Several other cities, including Tianjin on the coast east of Beijing and Wuhan, capital of central Hubei Province, also reported severe pollution.
