本期主题【全球气候变暖】

　　Global warming, a natural phenomenon,has been aheated topic in recent years. Global warming willredistribute global rainfall, make glacier andpermafrost melt and sea level rise, which not onlydoes harm to the balance of natural ecosystem, butalso threats human's food supply and livingenvironment. It's interesting that global warming is bad for some places but good for otherregions. For example, because temperature in cold areas in Antarctic and Arctic goes up,glacier will melt, thus making the habitat of animals decrease. While in the northeast ofChina, becoming warm means being able to plant grains of winter, thus raising agriculturalrevenue.

　　全球气候变暖是近年来全球一直热议的话题,是一种“自然现象”。全球变暧会使全球降水量重新分配，冰川(glacier)和冻土(permafrost)消融，海平面上升等，既危害自然生态系统的平衡，更威胁人类的食物供应和居住环境。有一个有趣的现象，就是全球变暧对有些地区是坏事，而对其他地区却是好事，比如，南北极的寒冷地区由于温度升高，导致冰川融化，动物栖息地减少。而在中国东北地区，天气变暖意味着可以种植冬季农作物，从而增加农业收入。
