Text 3 Up until a few decades ago,our visions of the future were largely-though by no means uniformly-glowingly positive.Science and technology would cure all the ills of humanity,leading to lives of fulfillment and opportunity for all.Now utopia has grown unfashionable,as we have gained a deeper appreciation of the range of threats facing us,from asteroid strike to epidemic flu and to climate change.You might even be tempted to assume that humanity has little future to look forward to.But such gloominess is misplaced.The fossil record shows that many species have endured for millions of years-so why shouldn't we?Take a broader look at our species'place in the universe,and it becomes clear that we have an excellent chance of surviving for tens,if not hundreds,of thousands of years.Look up Homo sapiens in the"Red List"of threatened species of the International Union for the Conversation of Nature（IUCN）,and you will read:"Listed as Least Concern as the species is very widely distributed,adaptable,currently increasing,and there are no major threats resulting in an overall population decline."So what does our deep future hold?A growing number of researchers and organisations are now thinking seriously about that question.For example,the Long Now Foundation has its flagship project a medical clock that is designed to still be marking time thousands of years hence.Perhaps willfully,it may be easier to think about such lengthy timescales than about the more immediate future.The potential evolution of today's technology,and its social consequences,is dazzlingly complicated,and it's perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage.That's one reason why we have launched Arc,a new publication dedicated to the near future.But take a longer view and there is a surprising amount that we can say with considerable assurance.As so often,the past holds the key to the future:we have now identified enough of the long-term patterns shaping the history of the planet,and our species,to make evidence-based forecasts about the situations in which our descendants will find themselves.This long perspective makes the pessimistic view of our prospects seem more likely to be a passing fad.To be sure,the future is not all rosy.But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans,and to improve the lot of those to come.32.The IUCN’s“Red List”suggest that human being are
推理判断题干问的是“濒危物种名单（Red List）”意味着人类怎么样了？我们根据“IUCN”和“Red List”很容易定位到第三段。首段说的是几十年前至今人们对未来所持的态度，第二段出现转折，表明目前人们对于未来的危机意识加重。第三段再次转折，表示第二段中人们所持态度是错误的，即“人类未来不会有太大的生存危机”，并且在此段首句表明观点后，用各种信息去论证和支持这一观点。“Red List”很显然也是用来说明这个观点的，并且指出人类这个物种是widely distributed，adaptab
