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，一位中国留学生在毕业典礼上发表了演讲。她的演讲很快就成为了热点话题，因为她批判中国的空气污染严重，给她的健康带来了很大的威胁。虽然她的演讲夸大了这个问题，但是，中国确实面临着许多污染问题。北京的雾霾在世界是出了名的，这是对人类破坏环境的惩罚。解决这个问题是需要时间的，并没有必要因此而否定我们的国家。即使是发达国家，它们也曾经遇到过这样的问题。我们可以从日常生活中做些事情来保护它，比如不乱扔垃圾。
