综合
阅读：beavers should not be released in England
1. Beavers use wood build dams,这样就会block the water flow
2. Beavers 会dig holes,然后使ground above腐烂，不利于farmland
3. Beavers’teeth are so strong that they will burrow in trees and thus kill the trees
听力：releasing beavers的好处大于坏处
1. Beavers并不会在每条河流中build dams,很多build dams的河流是still的
2. Beavers通常在Long river中，通常long river水流很快,beavers可以slow down the water flow,这样对农田有利
3. 把有些trees kill掉反而使vegetation多样化，因为部分树木挪调之后会使原本在树荫下的植物有更多的阳光，这样这些vegetation就可以长的更好，就会出现一个new ecosystem
