外一个医院很慢,医生的笔迹不好辨认等等。选项中,邮费的问题文中没有提到,
故A错误,没有好的记录系统文中也没有提到。抄写诊断书的内容文中也没有涉

你的过往病历,方便医生和患者的沟通,和患者信息的交换,更安全高效等。选项
中,文中没有说到患者可以不去抓药,也没有说医生不需要护士帮忙治疗,或者说
医院可以在急救室接受病人,A、B、C都没有提到,只有D正确,病人可以在家

知识点解析:推断题。根据文章的最后一段,作者提到如果操作不当,会使医生迷
惑降低病历的可信度,但是这些问题只是有时发生。可以推断还是需要今后的改
进。而没有说到需要电胸专业人员来避免危险.不可能解决医院的一切问题。电子
病例对医生、护士和患者都有利,故B、C、D错误,A正确。

院使用,虽然贵,但是收效很大,但是没有说到大多数机构都买不起,故A错
误,B正确。也没有提到电脑出错的问题,故C错误。电子病历只是方便了医生和
患者的沟通,但并不是说患者就可以不去医院了,故D错误。故选B。

6、Barkbeetles.
A、aredisappearingbecauseoftheincreaseofwildfires
B、areeasilykilledbywoodpeckersandnuthatches
C^laytheireggsunderthegroundatthebottomoftrees
D、havebecomeabletosurvivethewinter
标准答案:D
知识点解析•:细节题。本文讲述了因为全球变暖,导致一种害虫在森林肆虐的情
况。因为全球变暖,树木的树脂干枯,不能淹死入侵的害虫,导致害虫的繁殖量增
大,幼虫死亡率降低,在森林中肆虐。故A错误。"Woodpeckersandnulhatches
keepadultnumbersincheck,butwithwarmerwinters,beetlepopulationscan
quadrupleinayear,outpacingtheirpursuers^,故它的天敌不能有效地控制虫害,B
错误。由“Thegalleriesofeggstheylayinsidethebark..”,可以看出他们把卵产在树
皮下,故C错误。从"mildwintersinWyominghavehelpedthebeetlelarvae(幼
虫)survivetheseason”中看出D正确。
7、Whatistherelationshipbetweenbarkbeetlesandclimatechange?
A、Moreandmorebarkbeetlesdieduetoglobalwanning.
B、Barkbeetleshavemoreriskofdyinginwarmingwinters.
C、Globalwarmingcausesanincreaseinthenumberofbarkbeetles.
D、Thereisnorelationbetweenthem.
标准答案:C
知识点解析:细节题。从上题的解析中可以看出,气候变暖对于这种害虫的繁衍有
利.暖冬可以使他们的死亡率降低,故A、B、D错误。他们的关系是变暖可以导
致害虫数量的增长。
8、Whydowehavemorewildfiresnowthanbefore?
A、Becausethenumberofthebarkbeetlesisdecreasing.
Becausetreeswherebarkbeetleslivedryouteasilyandcatchfire.
C、Becausebarkbeetlespreventtheearthfromgettingwarmer.
D^Becausebarkbeetlesarecold-bloodedandneedfiretowarmuptheirbodies.
标准答案:B
知识点解析:推断题。眼据文章的第一段,气候变暖导致树木及土壤水分量减少,
导致火灾数量的增多。由此可见问题在于水分的减少。而这种害虫导致树木死亡,
死亡的树木含水量很低,就更容易着火,故选B。
9、Whatkindofchangeshasappearedinthelivingareaofbarkbeetles?
A、Theyaremovingfromthecoolercasttothewarmerwestareas.
B、Theyhavebecomeabletoliveinthehigherareasofthemountains.
C、TheyaremovingfromAlaskatoWyoming.
D^Theyhavecometoliveinthedeadtreesafterwildfires.
标准答案:B
知识点解析:细节题。由文章的最后一段,“Warmingisalsoexpandingthe
beetles'rangeintohigherakitudes.”可知,因为气候变暖,地球上高海拔地区也开始
温度升高,这样这种害虫的生活范围向上延展,可以在更大的范围内生活,故B
正确。这种扩大是海拔上的,立体的,而不是横向的,故A、C错误。D文中没有
提及。
10、Whichofthefollowingstatementistrue?
A、Thelifeexpectancyofthebarkbeetlesisbecomingshorter.
B、Globalwarmingdoesn,tinfluencetheearth'sbiologicalsystems.
C>Thenumberofwoodpeckersisrapidlyincreasingbecauseofwarmerwinters.
D、Wecanrelyonbarkbeetlestoindicateglobalclimatechange.
标准答案:D
知识点解析:细节题。艰据本文的大意(见第1题解析),A、B和文章的意思相
悖。C中因为暖冬数量增加的是这种甲虫,而不是啄木鸟,故错误。D这一细节在
文中结尾,“thebeetlesseemtobeareliableindicatorofglobalclimatechange''提及
过,故选Do

知识点解析:细节题。在很多国家,为了使本国的人民吃得更健康.政府正在准备
增加不健康食物的消费税,以减少人们对这些食物的购买。本题的答案可以从文章
的第—段得出."'governmentsaretryingtogetcitizenstoeatmorehealthily...Oneway
inwhichgovernmentsaretryingtodothisisbyincreasingtaxesonfoodsthat

没有提及。

governmentwaswrongtosaythatthefoodstheyproduceareunhealthy.Cheese,for
example,containsalotoffat»butitdoesnotseemtoleadtohealthproblemsinthe
wayotherkindsoffatdo.”即他们认为他们生产的食物不是不健康的.故选C。
13、Whatwasoneresultoftaxingfoodsthathavealotoffat?
A、Manypeopleavoidedpayingthetaxbyshoppingabroad.
B、ManypeoplebeganeatingtraditionalDanishfood.
C、Itmadehealthyfoodslikefruitandvegetablescostmore.

知识点解析:细节题。该细节在文章的第三段,“Sincethesecouldnotbeboughtin
Denmarkatreasonableprices,manyDanishpeoplebeganshoppingin
nearbycouniries.”即他们离不开这些食物,只能去邻国买这些产品。故A符合题
意。

B、ismoreconcernedaboutmoneythanthehealthofitscitizens
C、hasenoughinformationtoseeiftaxesonunhealthyfoodsareeffective
D、shouldaskothercountriestomakelawsagainstsellingfattyfoods
标准答案:B
知识点解析:细节题。医生的看法可以在文章的最后一段找到,umanydoctorssay
thatoneyearisnotlongenoughtoknowifthetaxhelpedDanish
citizens,health...TheyclaimthattheDanishgovernmentisworriedmoreaboutthe
economythanitisabouttheDanishpeople.”即他们认为政府考虑经济多些,而不是
人民的健康,故与B相符。
15、Whichofthefollowingstatementistrue?
A、Somepeoplethinkthatmakinghealthyfoodscheaperwouldworkbetterthanatax.
B、Healthexpertssaythatweshouldeatmoredairyproductsthanotherfoods.
C、Somekindsoffruitandvegetablesareasunhealthyasmeat.

应该降低健康食物的价格,故A正确。而文中健康专家说“weneedtoconsidereach
fbodscparatclyandnotsimplyworryabouthowmuchfatitcontains”.并没有说奶制品
更健康,故B错误。文中没有提到水果和蔬菜不健康,故C错误。D与文意相
反,不健康的食物有更高的税,人们为了避开交税而不会买不健康的食物,故选
