14、the panda”可知C项正确；根据第二段的“Professor of fisheries and wildlife”可知D项正确；第一段说自然保护区外还有许多适合大熊猫生存的栖息地，并没说大熊猫在外面生活得更好，故选B。2The purpose of developing habitat models is .Ato know where pandas actually live in ChinaBto build a larger nature reserve for the pandasCto develop conservation strategies for endangered

21、ever DSoC过去人们大量捕杀狼，然而后来国家通过法律保护狼，因此前后为转折关系。but也可表示转折，但but是连词，不用逗号分开。2A.farmers BsportsmenCsoldiers DofficersB此空从前文“because hunters were killing hundreds of them for sports”得出。3A.skin BcoveringCmeat DfurD有的人捕杀狼是为了它们的皮。4A.increased BreducedCimproved DchangedA因为有法律保护狼，因此狼的数量增加了。5A.killing BusingCeating

22、 DdestroyingD从空后的“their own food ”看，本空应该填“毁灭”。6A.supply BanimalsCstores DdeerA狼太多了，它们破坏了自己的食物供应。7A.hunter BdeerCfarmer DwolfB下文中的“People there also hunt deer.”等一系列关于鹿的叙述为重要提示。8A.joy BskinCfood DsafetyC文章一直在探讨食物链的问题，上下文中几处有“food”这一重要线索。9A.killed BharmedChunted DprotectedB在此A项有较大干扰性，作者说寒冷的冬季及食物的变化对鹿伤害

23、极大，但还不至于死亡。下一句“当鹿找不到食物时，它们就会死亡”也能说明这一点。10A.everyday BcoldCanimal DplantD气候的寒冷和植物的变化。11A.much BgoodCenough DfreshC鹿找不到足够的食物便会死亡。12A.stop BcontinueCremain DgoB如果狼继续杀死大量的鹿，鹿总有一天会灭绝，狼也会。13A.disappear BdieCreduce DstarveA从空后的“some day”看，作者在讲述未来的结果，联系空前的内容，鹿有一天会灭绝。14A.find BuseCchange DinsistC基于上面的原因，我们应该

24、改变这样的食物圈。15A.save BkeepCdefend DmakeA在此B项有较大干扰性，keep.from意思是“阻止做某事”，而save.from意思是“从中把挽救出来”。 16A.water BlandCforest DfarmD从下文我们得知，如果狼得不到足够的鹿，它们就会去袭击鸡等，因此保护好鹿，也会使some farm animals得到保护。17A.deer BharesCdogs DcowsDhare的意思是“野兔”，它不是农场的动物，因此B不合题意；在C、D两项中，cows是较容易捕杀的，因此D为最佳答案。18A.force BinsistCwant DorderCwant the United States government to do符合句意。A、D两项显然不合题意，insist构成的搭配为insist on doing，而不可以是insist sb.to do sth.。19A.scientists BsoldiersChunters DdoctorsA从空后的“to study the problem”可知答案。20A.right BnecessaryCuseful DnaturalB他们认为在有的地区捕杀狼而在数量少的地方保护狼是有必要的。
