2.Accordingtothesefigures,ourcompanyisdoingwell.從這些數(shù)字來看，我們的公司經(jīng)營得不錯。渡渡鳥是一種不會飛的鳥,僅產(chǎn)于非洲的島國毛里求斯。肥大的體型總是使它步履蹣跚,再加上一張大大的嘴巴,使它的樣子顯得有些丑陋。幸好島上沒有它們的天敵,因此,它們安逸地在樹林中建窩孵卵,繁殖后代。16世紀(jì)后期,帶著來復(fù)槍和獵犬的歐洲人來到了毛里求斯。不會飛又跑不快的渡渡鳥厄運降臨了。歐洲人來到島上后,渡渡鳥就成了他們主要的食物來源。從這以后,槍打狗咬,鳥飛蛋打,大量的渡渡鳥被捕殺。就連幼鳥和蛋也不能幸免。開始時,歐洲人每天可以捕殺到幾千只到上萬只渡渡鳥,可是由于過度的捕殺,很快他們每天捕殺的數(shù)量越來越少,有時每天只能打到幾只了。1681年,最后一只渡渡鳥被殘忍的殺害了,從此,地球上再也見不到渡渡鳥了,除非是在博物館的標(biāo)本室和畫家的圖畫中。ListeningEx3Choosethesentencewhichgivesthemainideaofthestory.Saywhatiswrongwiththeotherthree.Number2iscorrect.Number1iswrong.Itisnotfairtoblamethedodoforhis
