  新托福口语题目回忆版本二:

  标题:ecological trap(生态陷阱)

  定义:Normally speaking, correct signals as to where suitable habitats are will be given to animals. But because human have changed nature, consequently, those signals lead animals to dangerous habitats.

  正常来说, 动物会接收到提示适宜栖息地的正确信号,但因为人类改变了自然,所以信号会讲动物引入危险的栖息地。

  例子: For example, Mayflies usually lay eggs in water, and they can know if they are on the ground or on a lake by judging for the reflection of sunlight for water. Recently a lot of mayflies lay eggs on paved pebbles because the way the sun light reflects on paved pebbles is the same to that of water surface.

  例如蜉蝣一般在水中产卵,它们会依赖阳光在水中的反射来判断自己是在湖泊还是在地面上。而最近很多蜉蝣在铺路石上产卵就是因为阳光在铺路石上的反射方式与在水面上的相似。
