AccordingtoJohn,thebankclosesat4p.m.Eachmanwillbepaidaccordingtohisability.dodo渡渡鳥Listening

DoDo鳥是一種不會(huì)飛的鳥，僅產(chǎn)于毛里求斯肥。擁有肥胖的身子和巨大的嘴。

16世紀(jì)后期，歐洲殖民者來(lái)到了毛里求斯。不會(huì)飛又跑不快的DoDo鳥很快成為歐洲人來(lái)到島上后主要的食物來(lái)源。人們開始大量的濫捕濫殺可憐的DoDo鳥，有時(shí)每天可以捕殺到幾千只到上萬(wàn)只。由于過(guò)度的捕殺,很快島上DoDo鳥便得越來(lái)越少。1681年，最后一只DoDo鳥被殘忍的殺害后，從此，地球上再也見(jiàn)不到這種東西了，除非是在博物館的圖片中。Ex3Choosethesentencewhichgivesthemainideaofthestory.Saywhatiswrongwiththeotherthree.Number2iscorrect.Number1iswrong.Itisnotfairtoblamethedodoforhisdisappearance.Number3onlyexplainhalfthestory.Thedodoandmandidbecomefriendsbutonlybecausemanwantedtokillallthedodosaseasilyaspossible.Number4iswrongbecausetheotheranimalsandbirdsdidnotdomuchtosavethedodo.Theywarnedhimbutdidnothelphim.Listentothetapeandchoosethecorrectanswertocompleteeachsentence.1.Thedodois_____.A.fierceB.unkindC.friendlyD.foolish2.HewantstobelievethatManistellingthetruthbecause_____.A.ManisfriendlyB.hethinksManisfriendlyC.hethinksthebearsandmonkeyslieD.Manishisbestfriend3.Hedidn’trealizewhohadkilledmanyofhisfriendsuntil_____.A.MantoldhimthetruthB.theotherbirdstoldhimC.hesawhowhisfriendwasbeingkilledbyManD.themonkeystoldhimfierceadj.
