20、色液体，以掩护自己逃走。1.D.细节理解题。短文第二自然段一开始讲述的是蝗虫随庄稼颜色的改变而改变自身的颜色。联系“but birds cannot easily catch them.”这句话即可得出答案。2. C.细节理解题。本题所设的问题是：与周围植物颜色差别明显的昆虫如何逃避危险？第二自然段最后的“So they have to hide themselves for lives and appear only at night.”这句话是答案的出处。 3. A.细节理解题。这也是一道考查表层理解能力的题目。由第三自然段最后的“This is because they have the

21、 colors much like the trees.”这句话可以找到答案。 4. B. 细节理解题。根据“While the liquid spreads over, its enemies cannot find it. And it immediately swims away.”这两句话可知，这种鱼喷射出黑色液体的目的是让对方看不清自己，然后乘势逃走。另外，由“its enemies cannot find it.”可知，这种液体并不是用来杀伤对手的。所以答案是B。 5. C. 细节理解题。根据短文的叙述和列举的例子，显然可以看出它主要讲的是不同昆虫和动物身上的颜色的用途。换句话说，该短文是关于动物是如何用颜色来保护自己的。而A项中说的动物身上颜色的改变，B项中讲的不同动物身上的颜色，这两项虽然也是短文表达的意思，但并不能概括作者向我们表达的主要意思。
