描述的三种来拯救濒危的乌龟
R&L对照
Reading:
1.建造一片长叶森林;
2.把乌龟养大再放生;
3. 把他们放到适合他们生长的栖息地。
Lecture:反驳
1.不能提供足够的grass,因为需要periodical forest fire,而我们还不能放任森林大火;
2.小乌龟有传染病,放生后不仅不能被治疗,还会传染给其他野生乌龟;
3.这种乌龟有homing instinct,它们会本能的爬回以前生活的地方,不愿待在新的栖息地,还有一个危险是它们会爬过交通繁忙的地方。
新托福写作题目回忆版本二:
保护一种动物
passage给了3个solution:
1.建立保护区
2.现在研究所里养着,后面放生
3.elocate到新的地方
lecture反对原因:
1.保护区难以保证足够的食物,且那种树叶的保护区需要在大火烧掉树的特定情况下发生。
2.那个动物很容易感染病毒,尽管在研究所里被treat well,出去也容易被感染 。
3.动物有homing instinct,即便去了新的地方也会爬回原来的地方。然而migration的途中经常经过busy road,一不小心又要死了。
新托福写作题目回忆版本三:
阅读主要观点提取
总论点:生物学家提出了可以防止地鼠龟(gopher tortoise)消失的策略。
策略一:保护地鼠龟的栖息地。地鼠龟数量下降的一个重要原因是因为它们的栖息地遭到了破坏。地鼠龟生活在长叶松森林里,但是这些森林逐渐的被人类破坏。所以为了挽救地鼠龟,这些森林应该被保护起来或者种植更多的长叶松。
策略二:在研究站饲养地鼠龟,然后再将它们放回大自然。这个方法可以防止幼儿地鼠龟被捕食者抓到。一旦幼儿地鼠龟可以保护自己,它们就可以回到大自然了。
策略三:在地鼠龟消失的地方重新引入地鼠龟。新的地鼠龟繁殖出大量的后代,因此地鼠龟的整体数量会增加。
听力主要观点提取
总论点:阅读中提出的方法都是无效的。
解释一:保护和扩建森林是不可行的。只有在森林大火清除一些树木并且阳光折射地面的情况下,长叶松才会生长。问题在于我们通常都在预防森林火灾。如果没有周期性的森林大火,地鼠龟是没有足够的食物来维持生命的。
解释二:被圈养起来的地鼠龟是很容易得传染病的。在圈养的情况下,传染病是可以被治愈的。一旦地鼠龟被放回大自然,传染病是不可治愈的。同时,这些带有传染病的地鼠龟还有感染大自然中其他健康的地鼠龟。
解释三:将地鼠龟带入新环境也是不可行的。地鼠龟天生就有一种归巢的本能(homing instinct)。如果我们把一群地鼠龟放到一个新的环境里,它们会开始迁移。即使不会到原来的位置,它们也会迁移到它们自己选择好的栖息地。然而,迁移的过程也是很危险的,比如有很多地鼠龟都死在了马路上。
新托福综合写作范文
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.
