Recently, a Chinese student who studied abroad delivered a speech at the graduate ceremony. Her speech soon became the hot issue, because she criticized Chinese air pollution, which was a great threat to her health. Though her speech had exaggerated the problem, it is true that China has faced many pollution problems. The haze in Beijing is famous around the world, which is the punishment for human to ruin the environment. It needs time to fix the problem, but there is no need to deny our country. Even for the developed countries, they have once faced such problem before. We can do something in the daily life to protect it, such as do not throw away the rubbish. 
最近，一位中國留學生在畢業典禮上發表了演講。她的演講很快就成爲了熱點話題，因爲她批判中國的空氣污染嚴重，給她的健康帶來了很大的威脅。雖然她的演講誇大了這個問題，但是，中國確實面臨着許多污染問題。北京的霧霾在世界是出了名的，這是對人類破壞環境的懲罰。解決這個問題是需要時間的，並沒有必要因此而否定我們的國家。即使是發達國家，它們也曾經遇到過這樣的問題。我們可以從日常生活中做些事情來保護它，比如不亂扔垃圾。
