11.Australia's koalas could die out within 30years unless immediate action is taken to stop the losing in population,according to researchers.They say development,climate change and bushfires have all combined to reduce the number of wild koalas sharply.The Australian Koala Foundation said a recent survey showed the population could have dropped by more than half in the past six years.The number of koalas was once estimated to be more than 100,000,but now is as few as 43,000.
The foundation collected field data from 1,800sites and 80,000trees to calculate the numbers.In one area in northern Queensland estimated to have 20,000koalas a decade ago,a team of eight people could not find a single animal in four days of searching.
The foundation said besides problems caused by cutting down forests,hotter and drier conditions because of global warming had reduced the nutritional value of their main food,eucalyptus (桉树) leaves,leading to poor nutrition for them.Koalas,which live in the forests in Australia's east and south,are very picky about what types of the leaves they eat.
Foundation chief Deborah Tabart said:"The koalas are missing everywhere we look.It's really no tree,no me.If you keep cutting down trees you don't have any koalas."
She is hoping the new figures will persuade the government's Threatened Species Steering[.Com]Committee (TSSC) to list the koala as threatened.But committee chairman Bob Beeton said a decision was not likely recently and the koala's status as one of the country's favorite animals would not be a factor."There's a number of species which are attractive and people have special feelings towards them.We don't consider that,"Mr Beeton said.
13.The writer gives the example of the area in northern Queensland in Paragraph 3to show thatD.
A.the forests are being damaged heavily
B.the environment is being polluted seriously
C.koalas usually live in wild mountainous areas
D.the number of koalas is dropping quickly
14.Global warming is an important cause of koalas'reduction becauseB.
A.koalas can hardly stand the hot weather
B.the leaves koalas eat are losing nutritional value
C.koalas cannot get enough water to drink
D.the leaves koalas eat cannot grow in hotter and drier weather
15.According to Bob Beeton,C.
A.the koala is one of his favorite animals
B.a decision will be made to protect koalas in the future
C.they needn't pay special attention to koalas
D.koalas needn't be protected at all.
分析 研究显示,澳大利亚的考拉可能在30年内灭绝,除非立即采取行动阻止数量的流失.他们说发展,气候变化和山火都在大幅减少野生考拉的数量.
澳大利亚考拉基金会说,最近的一项调查显示,在过去六年考拉数量可能下降了一半以上.考拉的数量曾经估计超过100000,但现在只有43000.
基金会收集来自1800个网站和80000棵树来计算数字.在昆士兰北部一个十年前有20000只考拉的领域,一个八人的小组在四天的搜索中找不到一个动物.
基金会说除了砍伐森林造成的问题,全球变暖造成的更加燥热的气候条件已经减少了考拉主要食物-桉树的营养价值,导致考拉营养不良.考拉生活在澳大利亚东部和南部的森林里,对吃什么类型的树叶非常挑剔.
基金会首席Deborah说:"考拉失踪,我们到处都能看到.真的是没有树,没有我.如果你继续砍伐树木你将失去考拉."
她希望新数据将说服政府的濒危物种指导委员会(TSSC)列出考拉正在受威胁.但委员会主席鲍勃Beeton说最近做出决定不太可能,考拉作为国家的最喜欢的动物之一的地位不会是一个因素."有很多物种很吸引力,而且人们对他们有特殊的感情.我们不考虑这些."Beeton先生说.
解答 13-15 DBC
13题答案是D.细节理解题.The foundation collected field data from 1,800sites and 80,000trees to calculate the numbers.In one area in northern Queensland estimated to have 20,000koalas a decade ago,a team of eight people could not find a single animal in four days of searching 十年前有20000只考拉的区域在4天的搜索中找不到一只动物,可知考拉的数量在急剧下降.故答案是D.
14题答案是B.细节理解题.根据hotter and drier conditions because of global warming had reduced the nutritional value of their main food,eucalyptus (桉树) leaves,leading to poor nutrition for them.Koalas,which live in the forests in Australia's east and south,are very picky about what types of the leaves they eat.可知考拉对食物很挑剔,主要食物--桉树的叶子因全球变暖而营养价值下降.故答案是B.
15题答案是C.细节理解题.根据But committee chairman Bob Beeton said a decision was not likely recently and the koala's status as one of the country's favorite animals would not be a factor."There's a number of species which are attractive and people have special feelings towards them.We don't consider that,"Mr Beeton said.考拉作为国人最爱的动物不是受保护的因素,他们不考虑人们对动物的特殊感情.可知他们不对特殊关注考虑.故答案是C.
