综合:
保护某种濒危的海龟
阅读文章观点:
1. 保护并扩大一种长叶子植物的栖息地,海龟以这种植物为食
2. 先在研究所长大再放归自然
3. 统一将海龟们放归到适合它们生长的栖息地
听力反驳:
1. 这种植物对环境有特殊要求很难达到
2. 小海龟容易得病死亡
3. 这种乌龟有homing instinct,它们会本能的爬回以前生活的地方,不愿意待在新的栖息地,还有一个危险是它们可能会爬过交通繁忙的道路
范文
The author comes up with three strategies that can discourage gopher tortoise from disappearing. However, the professor thinks these methods are ineffective.
First, the reading claims that protect and expand long-leaf forest that is habitat of gopher tortoise is one of ways to control the declining. Nevertheless, the speaker says that there is no enough grass for tortoises to feed on. In fact, only in the situation that there are periodic forest fires that clear out some trees and let the sunshine reach the forest floor, can grass grow. But the problem is people usually prevent forest fires. Consequently, tortoises won’t have enough grass to survive.
Second, the writer proposes another strategy that young tortoises are bred in research stations and then release them into wild when they grow large enough. But the professor indicates that breeding tortoises in captivity is risky. It is because captive tortoises often contract infectious diseases and these diseases cannot be treated once tortoises are released into the wild. Furthermore, tortoises with diseases will infect the wild tortoises.
Third, the professor refutes the viewpoint showed in passage by saying that reintroducing tortoises into new areas is dangerous for tortoises and even kill them. The fact is if tortoises are put in a new environment, they will start migrate to either their original home or a habitat that was carefully chosen because they have a homing instinct. Also, they have high possibility to be killed because migrating tortoises often cross busy roads.
