around the world may feel that the climate has been getting steadily warmer and warmer in recent years.Places which used to be abundant in snowfall have frequently experienced snow-free winters.Drought lasts longer in some dry areas.People find that without air conditioners they could hardly work or fall asleep on hot summer days.,The side effects of global warming are alarming.A warmer global climate melts the ice caps,raising sea levels.What is more,it disturbs weather patterns,causing droughts,severe storms and hurricanes.People suffer a lot from disasters relevant to

caused the worlds first horses to shrink nearly 50 million years ago.,In fact,a team from the universities of Florida and Nebraska says it has found a link between the Earth heating up and the size of mammalshorses,in this case,the last time the world heated up.,The scientists used fossils to follow the evolution of horses from their earliest appearance 56 million years ago.,As temperatures went up their size went down,and vice versa;at one point they were as small as a house cat,said Dr Jonathan Bloch,curator of the Florida Museum of Natural History.,The scientists say that the current warming could have the same effect on mammalsand could even make humans smaller.,21/26,重点词汇,重点句型,重点语法,功效,走近高考,拓展阅读,“Horses started out small,about the size of a small dog like a miniature schnauzer.Whats surprising is that after they first appeared,they then became even smaller and then dramatically increased in size,and that exactly corresponds to the global warming event,followed by cooling.,“It had been known that mammals were small during that time and that it was warm,but we hadnt understood that temperature specifically was driving the evolution of body size,”Dr Bloch said in the“Science”journal.,22/26,重点词汇,重点句型,重点语法,功效,走近高考,拓展阅读,译文,全世界人或许以为近几年气候正逐步变得越来越暖和。过去降雪丰富地方已经经常经历无雪冬天了。干旱在一些较干地域连续时间更长了。人们发觉,没有空调他们几乎无法在酷热夏日里工作或入睡。,全球变暖副作用在敲响警钟。更暖和气候使冰块融化,海平面上升。而且,全球变暖扰乱了天气模式,造成干旱、严重暴雨和飓风。与全球变暖相关灾难使人们受了很多苦。,这里相关于全球变暖另一个发觉。,科学家警告说,全球变暖可能会使人类变矮。科学家宣称已经找到证据,:,近,5000,万年前全球变暖就曾让世界上最早马个头变小。,23/26,重点词汇,重点句型,重点语法,功效,走近高考,拓展阅读,实际上,来自佛罗里达州和内布拉斯加州大学一支研究团体称,他们已经找到地球变暖和哺乳动物个头之间联络。这一案例中马变矮现象是上一次全球变暖时发生。,科学家用化石来追溯马从,5600,万年前诞生至今进化历程。,伴随气温上升,马个头变小,;,反之,气温下降,马个头就变大。佛罗里达自然历史博物馆馆长乔纳森,布洛赫博士说,它们曾一度像家猫那么小。,科学家称,当前全球变暖可能也会对哺乳动物产生一样影响,甚至可能会让人类个子也变小。,布洛赫博士在科学杂志中写道,:“,马最初个头很小,和一只小狗个头差不多,大约也就像一只迷你型雪纳瑞犬那么大。令人诧异是,在马诞生后过了一段时间,它们个子变得更小,之后个头又显著变大,而这些改变与全球变暖既而变冷恰好是相对应。,24/26,重点词汇,重点句型,重点语法,功效,走近高考,拓展阅读,“,我们已经知道哺乳动物在那个时期个头较小,而那个时期气候也较暖,但我们还未意识到正是温度驱动着身体大小进化。,”,词海拾贝,1,.abundant,b,nd,nt,adj.,丰富,大量,2,.mammal,mml,n.,哺乳动物,3,.curator
