求大神帮翻译一下，救急啊！！！

A study suggests that dirty air can reduce lung development. Researchers at the University of Southern California in Los Angeles published their work in the "New England Journal of Medicine". About one thousand seven hundred children from different communities in Southern California took part in the study. The scientists tested the children every year for eight years, starting at age ten. They say this is the longest study ever done on air pollution and the health of children. The scientists found that children who lived in areas with the dirtiest air were five times more likely to grow up with weak lungs. Many were using less than eighty percent of normal lung strength to breathe. The damage from dirty air was as bad as that found in children with parents who smoke. Children with reduced lung power may suffer more severe effects from a common cold, for example. But the researchers express greater concerns about long-term effects. They say adults normally begin to lose one percent of their lung power each year after age twenty. The doctors note that weak lung activity is the second leading cause of early deaths among adults. The first is smoking. By the time people are eighteen, their lungs are fully developed, or close to it. The doctors say it is impossible to recover from any damage. Researchers say they are still not sure how air pollution affects lung development. They believe that pollution affects the tiny air spaces where oxygen and carbon dioxide (二氧化碳) are exchanged. Arden Pope is an economics professor at Brigham Young University in Provo, Utah. Professor Pope wrote a commentary about the study. He noted that air quality in Southern California has improved since the study began in the early nineteen-nineties. Clean-air laws have reduced pollution from vehicles, industry and other causes. But dirty air is still a problem in areas of California and other places. Professor Pope says continued efforts to improve air quality are likely to provide additional improvements in health.

一项研究表明,肮脏的空气可以减少肺癌的发展。在洛杉矶南加州大学工作的的研究人员发表了他们的成果在“新英格兰医学杂志”。大约一千七百儿童来自不同社区在南加州参加了这项研究。科学家们每年测试这些孩子持续了8年,在他们十岁时开始。他们说这是最长的一次研究空气污染和孩子的健康。科学家们发现,孩子住在肮脏的空气的地区,肺部成长比在健康地区的孩子弱了5倍。许多人使用的正常肺强度低于80%去呼吸。这个危害来自肮脏的空气，最糟糕的是孩子的父母吸烟。孩子的肺强度减少可能遭受更严重的疾病来自同样的寒冷，比如。但是研究人员表示最关心的是长时间的影响。他们说成年人通常开始失去百分之一的肺能力在20岁以后的每一年。医生指出,弱肺活动是成年人早期死亡的第二个主要原因。第一个是吸烟 。十八岁的人,他们的肺发育完全,或接近它。医生说那是不可能的从任何伤害中恢复过来。研究人员说他们仍然不知道空气污染如何影响肺发展 。他们相信污染是影响微小的空气，当氧气与二氧化碳交换的时候。Arden Pope是一名经济学教授在Brigham Young University in Provo。。。pope教授写了一个评论关于这个研究。他指出,在南加州的空气质量已有所改善因为这个研究早在。。。就开始了。
空气法已经减少来自汽车，工业和其他原因的的污染。但是肮脏的空气仍然是一个地区的问题。Pope教授说继续改善空气质量能够提供另外的改进在人们的健康上

话说这是几年级的文章。。。。
