高考英语一轮复习Unit4Globalwarming学案新人教版选修6全球变暖晨读·经历Refresh Our EnvironmentAs the director stated on behalf of his researching group, the data of this graph makes a clear presentation of the future environmental tendency. On one hand, the quantity of fuel keeps on decreasing by 9% per year while the growth of a wide range of pollution has been a global trend. On the other hand, the mildly but steadily going up of the average temperature is resulting in catastrophes like widespread floods. Without disagreement, they subscribe to the view that it is humans’ existence and their randomly consuming energy that result in this phenomenon.Many people have a commitment that developing nuclear power or energy from outer space will stop bad consequences coming about. However, scientists and educators are opposed to this view even if our needs may be met on the whole. They tend to advocate refreshing our circumstances by saving energy and recycling waste.It is suggested that we use energy-saving appliances such as electrical motors, microwaves and so on and not be casual about little things like recycling a can. So please glance around and see what you can do. So long as everybody makes contribution, we will not have to put up with this problem anymore.复原环境生气正如那位主任代表他的研究小组所说明的那样，这张图表的数据清晰地描述了以后环境的趋势：一方面，燃料的数量以每年9%的速度连续减少，同时，大范畴污染的增长差不多成为一种全球趋势;另一反面，平均气温轻微却稳固地升高正在造成像广泛的洪涝那样的灾难。
