标题:
❶ Revealing Coloration 00:45 seconds
❷ Many animals use coloration to protect themselves from predators.
❸ One defensive strategy involving the use of coloration is what is known as revealing coloration.
❹ Animals employing this strategy have an area of bright color on some part of their body, this bright color is usually hidden from predators’ view. When approached by a predator, the animal suddenly reveals the area of bright color, this unexpected display of color startles or confuses the predator and provides the would-be-prey with an opportunity to escape.
关键点
记Title:
由于task 4的阅读主要是关于某一个科学术语的解释和说明,考生在开始阅读的第一秒钟就应该迅速在纸上纪录下阅读的题目——即科学术语本身。
记定义:
常见的表示定义的提示词有 refer to, known as, is, is called, etc.
注意点:
若定义过长或者很难确定的时候,考生应当舍弃该定义,但必须说出阅读文章中的title.
Task 4中的定义句不一定出现在段首,也非常可能出现在段尾或者段中。
文本分析
Title:
Revealing Coloration
考生对Coloration一词较熟,可预测段落解释重点放在Revealing上。
定义:
❸中重复出现了标题Revealing Coloration,并且有非常明显的提示词known as 。结合内容,动物保护色是动物进行自我防御的一种策略。因此,该句是定义句。
注意点:
很多考生认为定义句一般出现在段落开头,但❷中指出许多动物用颜色作为保护,以预防捕食者的袭击。这属于背景叙述,不是定义句。
❹中是对动物保护所采取的strategy的的具体描述,因为从句较长,考生应该对内容加以概括或适当舍弃。
