试题习题、尽在百度 Task 1 ：阅读下列短文，从每题所给的四个选项(A 、B 、C 和D) 中，选出最 佳选项. (2015·安徽，D)There are an extremely large number of ants worldwide.Each individual (个体的) ant hardly weighs anything ，but put together they weigh roughly the same as all of mankind.They also live nearly everywhere ，except on frozen mountain tops and around the poles.For animals their size ，ants have been astonishingly successful，largely due to their wonderful social behavior. In colonies (群体) that range in size from a few hundred to tens of millions ，they organize their lives with a clear division of labor.Even more amazing is how they achieve this level of organization.Where we use sound and sight to co unicate，ants depend primarily on pheromones (外激素)，chemicals sent out by individuals and smelled or tasted by fellow members of their colony.When an ant finds food ，it produces a pheromone that will lead others straight to where the food is.When an individual ant comes under attack or is dying ，it sends out an alar pheromone to warn the colony to prepare for a conflict as a defense unit. In fact，when it comes to the art of war ，ants have no equal.They are completely fearless and will readily take_on a creature much larger than themselves ，attacking in large groups and overcoming their target.Such is their devotion to the co on good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy. Behaving in this selfless and devoted manner ，these little creatures have survived on Earth for more than 140 million years，far longer than dinosaurs.Because they think as one，they have a collective (集体的) intelligence greater than you would expect from its individual parts. 【语篇解读】 本文是说明文.文章主要讲的是蚂蚁.单个的蚂蚁显得微不足 道，但成群结队的蚂蚁却蕴含着巨大的力量.蚂蚁的数量之众，加起来可以与人 类的重量相媲美.蚂蚁分布极为广泛，除了寒冷的山顶和两极
