编者按：全球变暖已成为科学界争论的话题。很多科学家认为全球变暖是由人类活动造成的，由于人们焚烧化石矿物或砍伐并焚烧森林，产生了二氧化碳等多种温室气体，导致全球气候变暖。有的科学家认为全球变暖是谣传，甚至还有科学家认为全球变暖事实上是好事，因为这样可以允许人们在很多原来冰冻的地区种植农作物。不管怎样，全球变暖会使全球降水量重新分配，冰川和冻土消融，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。避免温室效应，势在必行。 There is a huge argument going on in the world these days and it is centered on the notion that our planet is warming up. It’s called global warming and it postulates that our use of fossil fuels such as coal and oil and our destruction of large areas of forest across the world have combined to create so-called greenhouse gases. These gases prevent the heat from sunlight and other sources from radiating away into space and the trapped heat is slowly causing all sorts of negative effects. Those who warn us about all this point to receding ice caps at the north and south poles, less snow in winter, smaller glaciers in the mountains and so on. They say the consequences will be dire . There is an argument because not everyone believes that global warming is taking place. The 阅读全文>> |

One decided that it would be much better to go first. He thought, "The road will not be rutted by the carts, the bullocks will be able to choose the best of all the grass, we will find the best fruits and vegetables to eat, my people will appreciate my leadership and, in the end, I will be able to bargain for the best prices." The other merchant considered carefully and realized there were advantages to going second. He thought, "My friend's carts will level the ground so we won't have to do any road work, his bullocks will eat the old rough grass and new tender shoots will spring up for mine to eat. In the same way, they wi...阅读全文>> |
