Task Overview

Reading Passage

Many animals use coloration to protect themselves from predators. One defensive strategy involving the use of coloration is what is known as revealing coloration. 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.

Original Answer: ~~The reading passage illustrates the concept of revealing coloration, which is a strategy for the animals to escape from its predators.~~ The reading passage introduces the concept of revealing coloration, a strategy animals use to escape from their predators. (将句子结构简化，使其更自然) ~~And the professor uses two examples to illustrate this.~~ The professor provides two examples to demonstrate this concept. (使用更高级的词汇) The first one is ~~peanut bug~~ the peanut bug, which has its front wing colored so that it can blend in with the environment. And it also has the back wings, which is usually hidden, but has some bright spots on it. So when the predator attacks, it will reveal its back wing and surprise the predator with its bright spots so that it has a chance to escape. And the second example is a morpho butterfly, which has some part of its body that is shiny and reflects sunlight. So when the predator attacks, the butterfly would fly away and the flash of the light reflected by the part of the body would make the predator, which is the bird, hard to follow so that it can escape.

Revised Answer (140 words):

The reading passage introduces the concept of revealing coloration, a strategy animals use to escape from their predators. The professor provides two examples to demonstrate this concept. The first example is the peanut bug, which possesses front wings that are colored to blend in with its surroundings. Its back wings, usually hidden, have bright spots on them. When a predator attacks, the peanut bug reveals its back wings, startling the predator with the bright spots and providing an opportunity to escape. The second example is the morpho butterfly, which has shiny parts on its wings that reflect sunlight. When a predator, such as a bird, attacks, the butterfly takes flight, and the flashes of light reflected by its wings make it difficult for the bird to follow, allowing the butterfly to escape.
