一、英译汉
Heat stress also adversely affects milk production, meat quality and dairy cow reproduction.In addition， warmer summer temperatures have been shown to suppress appetites in livestock and hence reduce weight gain.For example, a study conducted in Appalachia found that a 5℃ increase in mean summer temperature caused a 10% decrease in cow, calf and dairy operations.
Provided there is adequate moisture, warmer temperatures and elevates CO2 concentrations are generally expected to increase growth rates in grasslands and pastures. It is estimated that a doubling of atmospheric CO2 would increase grassland productivity by an average of 17%, with greater increases projected for colder regions and moisture-limited grassland systems.However, study results tend to vary greatly with location, and changes in species composition may affect the actual impacts on livestock grazing.For instance, studies have noted future climate changes,particularly extreme events, may promote the invasion of alien species into grasslands, which could reduce the nutritional quality of the grass.

一、英译汉
热浪对牛奶生产、肉制品质量以及奶牛繁殖也很不利。另外，研究表明，夏季气温较高会抑止家畜的食欲，从而影响其体重增长。如阿巴拉契亚地区的一项研究表明，夏季平均气温上升5摄氏度，会导致奶牛、肉牛和奶制品产业产值减少10%。
假设湿度适宜，较高的气温和二氧化碳浓度通常会提高草场和草原的生长率。据估计，大气中二氧化碳浓度翻一翻，草场产量就会平均增长17%，在较冷的地区和湿度较低的草场上增长率更高。然而，研究结果地区差异很大，而物种构成的变化，也会使气候变化对家畜放牧的实际影响有所不同。比如，多项研究指出，未来气候变化，尤其是极端气候情况的出现，会助长外来物种侵入草场，从而降低草的营养价值。
二、汉译英
每当酷暑来临，我们的各种媒体上都会有商家销售空调的报道，比如一天售出几百台，或是一个月售出几千台。但是却没有人去计算这么多制冷剂会产生多少消耗臭氧层物质，这么多空调又会消耗多少能源，排放多少二氧化碳？在夏天的商务会议中，一些会议室的空调开得很大，温度低得让人发冷，还有的房间甚至开着窗子吹空调。
二、汉译英
Whenever a hot summer approaches, the news media report the air-conditioner manufacturers’ sales promotions, with daily sales of hundreds of units, and monthly sales in the thousands. But nobody has calculated how much ozone-depleting substance the refrigerants will produce, and how much energy the numerous air-conditioners will consume, and how much carbon dioxide (CO2) will be emitted. In summertime business meeting rooms, the air conditioners are often on at full blast, leaving participants shivering and sometimes making it necessary to open a window is to let some of the cold air out.
