Read the following text(s) and write an essay to 1) summarize the main points of the text(s), 2) make clear your own viewpoints, and 3) justify your stand. In your essay, make full use of the information provided in the text(s). If you use more than three consecutive words from the text(s), use quotation marks( ). You should write 160-200 words.American beverage giant Coca-Cola is offering a hefty environmental hardship allowance to its China-based expatriate employees, as foreign companies struggle to attract and retain staff with many people scared off by chronic pollution.China s hazardous air pollution, with just three out of 74 cities last year meeting minimum government standards, has become the key issue for foreign companies looking to post workers to cities such as Beijing or Shanghai. Many companies offer better medical insurance benefits, more paid trips home and subsidies for air filters to the roughly half a million foreigners working in China.Australian architectural firm Hassell provides its staff in China with face masks to travel to and from work. It also changes its air filters every week during periods of heavy pollution. In Australia, you might do that every year, said Peter Duncan, Hassell s managing director for Asia, who is based in Shanghai.Three decades of double-digit growth and lax regulation has taken its toll on China s environment. According to environment ministry statistics only three cities out of 74 met government standards for pollution last year.In Beijing, more than half of the days in May failed to meet government standards for air quality, while Shanghai fared slightly better with 58 per cent of days in the commercial capital-considered satisfactory.The World Health Organisation said earlier this year that air pollution was responsible for the deaths of 3.7 million people under the age of 60 across the globe in 2012.Peter Arkell, managing director Asia for recruitment firm Swann Global, said the Coca-Cola allowance showed the company was having trouble retaining and attracting staff to China. I hear more and more stories about executives not extending their contracts because they don t think China is a good place to bring up a family, he said. It (the environmental payment) is a way of addressing the air pollution issue but it does look like a pretty generous payment to me.
