3.Soon enough,we will lose some of the most amazing sites on Earth!The Great Barrier Reef---Rising air temperatures will cause sea temperatures to rise as well.All life supported by the oceans will be affected with this shock to their ecosystem.Coral are some of the most vulnerable marine animals and we are already watching whole reefs disappear.The Great Barrier Reef in Australia is no exception and will continue to shrink as the temperatures rise!These reefs are some of the best in the world for diving,but they will soon disappear!Venice---Sprawing across(横跨)hundreds of small islands in Northeast Italy,Venice is at extreme risk of sinking into the Adriatic Sea.Rising sea levels are in fact a serious threat to many coastal cities located at sea level.Lucky for us,however,Venice is developing a series of sea walls to protect the city in times of high tide.
Glacier(冰川)National Park---Glacier National Park was once covered by over 150glaciers,but by 2005it only had about 27!Located in Montana,Canada,this park is over a million acres and has a huge plant and wildlife population.As temperatures rise,the glaciers and ice melt,which will upset the ecosystems sustaining over a thousand plant species and hundreds of animals.
The Amazon---The cause behind the disappearance of these fantastic places ultimately comes down to humans.Our expansion usually requires cutting down forests for land,fuel and materials,but rarely considers the consequences.These forests are sources of food and medicine for just about everyone on the planet!
What will happen if we lose these valuable places and beautiful destinations?!

分析 本文讲述了我们正在失去一些地球上惊奇的景观,而造成这一现状的原因是气温上升引起的海平面升高以及人类的破坏环境.
解答 8.C.细节理解题.由第一段The Great Barrier Reef---Rising air temperatures will cause sea temperatures to rise as well.All life supported by the oceans will be affected with this shock to their ecosystem可知海水温度上升影响了生态系统,导致了珊瑚虫死亡,故选C.
9.B.细节理解题.由第二段Rising sea levels are in fact a serious threat to many coastal cities located at sea level可知海平面上升对许多位于海平面的沿海城市来说是一个严重的威胁,故选B.
10.A.细节理解题.由第三段Located in Montana,Canada,this park is over a million acres and has a huge plant and wildlife population,可知冰川自然公园在蒙大拿州占据很大的面积,故选A.
11.D.细节理解题.由最后一段Our expansion usually requires cutting down forests for land,fuel and materials可知,亚马逊雨林的缩小是因为人类扩张土地,砍伐森林获取材料,而其他三个都是由于气候变暖,故选D.
点评 本篇文章都是细节推理题,答题的已给选项也一般不会和短文相关词语完全相同,需要考生自己理解句子,延伸推理出题目答案,比一般细节理解题偏难.
