than twice the length of the Hoover Dam,and can be seen from space.The mammals use trees,mud and stones to make a type of moat(壕沟) where they can use their swimming skills to evade(躲避) any predators(食肉动物).The families of beavers live in lodges on the dams and spend their days adding to and repairing the incredible structures.While beaver dams are often found to be around 1,500 feet in length,this one has surprised biologists because of its length.The dam is located on the southern edge of Wood Buffalo National Park in northern Alberta,Canada.It is thought that several beaver families joined forces to create the big dam that contains thousands of trees and must have taken many months to complete.The dams are an important part of the ecology and wider environment,and climate change can be judged by the spread of the dams.Sharon Brown,a biologist from Beavers: Wetland and Wildlife,an educational organisation in North America,said:“Beavers build dams to create a good habitat.They are very agile(灵活的) in the water,but they’re a bit slow moving on land.”“They create a habitat with lots of water,like a moat,around their lodges so they can swim and dive,and keep one step ahead of predators.”“They also use water to move the trees they use in their dams,because it is easier floating branches on the water than dragging them over land.”“Their dams are also beneficial because they slow the flow of water leading to less drought and less flooding.And when plant matter dies in water,it turns into peat(泥炭) and that is one of the best ways for storing carbon dioxide.”【语篇解读】世界上最长的海狸水坝位于伍德布法罗国家森林公园,长2,790英尺,是胡夫水坝的两倍多,可以从太空看到。海狸水坝可以延缓水的流动,减少干旱和洪灾的发生。4.What does the passage mainly tell us?A.The world’s longest man-made dam.B.The biggest woodland

height答案A解析细节理解题。根据第二段的最后一句“Itisthoughtthatseveralbeaverfamiliesjoinedforcestocreatethebigdamthatcontainsthousandsoftreesandmusthavetakenmanymonthstocomplete.”可知,是几个海狸家庭合作建成了这个大坝,所以选A项。6.Why do
