2.Accordingtothesefigures,ourcompanyisdoingwell.从这些数字来看，我们的公司经营得不错。渡渡鸟是一种不会飞的鸟,仅产于非洲的岛国毛里求斯。肥大的体型总是使它步履蹒跚,再加上一张大大的嘴巴,使它的样子显得有些丑陋。幸好岛上没有它们的天敌,因此,它们安逸地在树林中建窝孵卵,繁殖后代。16世纪后期,带着来复枪和猎犬的欧洲人来到了毛里求斯。不会飞又跑不快的渡渡鸟厄运降临了。欧洲人来到岛上后,渡渡鸟就成了他们主要的食物来源。从这以后,枪打狗咬,鸟飞蛋打,大量的渡渡鸟被捕杀。就连幼鸟和蛋也不能幸免。开始时,欧洲人每天可以捕杀到几千只到上万只渡渡鸟,可是由于过度的捕杀,很快他们每天捕杀的数量越来越少,有时每天只能打到几只了。1681年,最后一只渡渡鸟被残忍的杀害了,从此,地球上再也见不到渡渡鸟了,除非是在博物馆的标本室和画家的图画中。ListeningEx3Choosethesentencewhichgivesthemainideaofthestory.Saywhatiswrongwiththeotherthree.Number2iscorrect.Number1iswrong.Itisnotfairtoblamethedodoforhis
