【总论点】beavers
【阅读部分】
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
【听力部分】
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
【参考范文】
The listening lecturer talks about three advantages to release beavers in England, and he asserts that the facts mentioned in the reading passage are inaccurate and different from reality.
First, according to the lecturer, it is not true that beavers use wood to build dams, which would block the water flow. This is because beavers wouldn’t build dams in every
river and the water flow of rivers in which they build dams is usually still. This directly refutes what the reading passage indicates.
Moreover, the professor argues that there is no solid evidence showing that beavers can dig holes causing the ground above rotten, which is detrimental to farmland. On the contrary, beavers often live in long rivers and the water flow of those rivers is usually very fast, so beavers can slow down the water flow, which is beneficial to farmland. This is another part where the listening lecture contradicts the reading passage.
Last but not least, the lecturer asserts that it is positive to the ecosystem that beavers use their strong teeth to burrow in trees and kill the trees. He thinks that when some trees are killed, the vegetation under the trees can be more diverse because when some of the killed trees are carried away, more plants under the trees before can obtain more sunshine, which could allow this vegetation to grow better and a new ecosystem will appear.
