1、Thecommunicationbypaperbetweendoctorshasproblemspartlybecause.

A、itcostsalargeamountforpostage

B、somedoctorshavedifficultyreadingthehandwritingonthepaper

C、thereisn'tagoodfillingsystemtorecordthedocument

D、ittakestoomuchtimetocopywhatiswritteninthediagnosis

標準答案:B

知識點解析:細節(jié)題。該細節(jié)在文章的第一段開頭.如把病歷從一個醫(yī)院轉(zhuǎn)移到另

外一個醫(yī)院很慢,醫(yī)生的筆跡不好辨認等等。選項中,郵費的問題文中沒有提到,

故A錯誤,沒有好的記錄系統(tǒng)文中也沒有提到。抄寫診斷書的內(nèi)容文中也沒有涉

及,只有B,書寫很難辨認文中提到了,故選B。

2、Whatwasmadepossiblebyadoptingcomputertechnologyinmedical

communication?

A、Patientsdon'thavetocometothephannacytopickuptheirmedicine.

B、Doctorscanprovideatreatmentwithouttheassistanceofnurses.

C^Hospitalscanacceptmorepatientsattheemergencyroom.

DxPatientsathomecancoinmnnicatewiththeirdoctorabouttheirbloodpressure.

標準答案:D

知識點解析:細節(jié)題。該細節(jié)在文章的第二、三段,比如醫(yī)生可以在第一時間知道

你的過往病歷,方便醫(yī)生和患者的溝通,和患者信息的交換,更安全高效等。選項

中,文中沒有說到患者可以不去抓藥,也沒有說醫(yī)生不需要護士幫忙治療,或者說

醫(yī)院可以在急救室接受病人,A、B、C都沒有提到,只有D正確,病人可以在家

和醫(yī)生溝通自己的血壓。

3^Inmakingprescriptions,.

A、doctorsshouldbecarefulnottowritedownpersonalinformation

B、itisdifferenttofindoutallthepatient,sallergies

C、thenewtechnologyhelpsavoiderrorsabouttheamountofmedication

D、doctorsandnursesworktogethertodoublecheckwhoreceivedthemedication

標準答案:C

知識點解析:細節(jié)題。艱據(jù)文章的第三段,在處方方面。4ithcycanalsoremindthe

doctoraboutpotentialadversedrug-druginteractionsorpatientdrugallergies,and

evenrecommendanadjusteddosebasedonapatient'skidneyfunction,,?''intravenous

drugsarcdeliveredthrough4smartpumps'thatensurethedoseisacceptable”,即提醒醫(yī)

生藥物間不良的相互作用或藥物過敏,還會根據(jù)患者的腎功能推薦藥量.可以控制

靜脈注射的約量等等,選項中只有避免約物用量錯誤符合題意。

4、Computerizinghcalth-caresystems.

A、arestillimprovingandbecomingsafer

B、requiremanyspecialistsaboutcomputerstoavoidaccidents

C、solveeveryproblemwehavenowinhospitals

D^areconvenientfordoctorsandnurses,butnotforpatients

標準答案:A

知識點解析:推斷題。根據(jù)文章的最后一段,作者提到如果操作不當(dāng),會使醫(yī)生迷

惑降低病歷的可信度,但是這些問題只是有時發(fā)生??梢酝茢噙€是需要今后的改

進。而沒有說到需要電胸專業(yè)人員來避免危險.不可能解決醫(yī)院的一切問題。電子

病例對醫(yī)生、護士和患者都有利,故B、C、D錯誤,A正確。

5、Whichofthefollowingstatementsistrue?

A、Ihcnewhcalth-carcsystemwithcomputersistooexpensivetobeadoptedbymost

medicalinstitution.

B、Thenumberofhospitalswheredoctorsuseacomputerizedhealth-caresystemis

increasing.

C>Evencomputersmakemistakes,soitissaferfbrdoctorsandnursestocheckeach

prescription.

D、Inthefuture,patientsdon'thavetogotothehospitalbecausetheycangetthe

diagnosisandtheprescriptiononline.

標準答案:B

知識點解析:細節(jié)題。文章的第一段和最后一段提到這種系統(tǒng)正在被越來越多的醫(yī)

院使用,雖然貴,但是收效很大,但是沒有說到大多數(shù)機構(gòu)都買不起,故A錯

誤,B正確。也沒有提到電腦出錯的問題,故C錯誤。電子病歷只是方便了醫(yī)生和

患者的溝通,但并不是說患者就可以不去醫(yī)院了,故D錯誤。故選B。

6、Barkbeetles.

A、aredisappearingbecauseoftheincreaseofwildfires

B、areeasilykilledbywoodpeckersandnuthatches

C^laytheireggsunderthegroundatthebottomoftrees

D、havebecomeabletosurvivethewinter

標準答案:D

知識點解析?:細節(jié)題。本文講述了因為全球變暖,導(dǎo)致一種害蟲在森林肆虐的情

況。因為全球變暖,樹木的樹脂干枯,不能淹死入侵的害蟲,導(dǎo)致害蟲的繁殖量增

大,幼蟲死亡率降低,在森林中肆虐。故A錯誤。"Woodpeckersandnulhatches

keepadultnumbersincheck,butwithwarmerwinters,beetlepopulationscan

quadrupleinayear,outpacingtheirpursuers^,故它的天敵不能有效地控制蟲害,B

錯誤。由“Thegalleriesofeggstheylayinsidethebark..”,可以看出他們把卵產(chǎn)在樹

皮下,故C錯誤。從"mildwintersinWyominghavehelpedthebeetlelarvae(幼

蟲)survivetheseason”中看出D正確。

7、Whatistherelationshipbetweenbarkbeetlesandclimatechange?

A、Moreandmorebarkbeetlesdieduetoglobalwanning.

B、Barkbeetleshavemoreriskofdyinginwarmingwinters.

C、Globalwarmingcausesanincreaseinthenumberofbarkbeetles.

D、Thereisnorelationbetweenthem.

標準答案:C

知識點解析:細節(jié)題。從上題的解析中可以看出,氣候變暖對于這種害蟲的繁衍有

利.暖冬可以使他們的死亡率降低,故A、B、D錯誤。他們的關(guān)系是變暖可以導(dǎo)

致害蟲數(shù)量的增長。

8、Whydowehavemorewildfiresnowthanbefore?

A、Becausethenumberofthebarkbeetlesisdecreasing.

Becausetreeswherebarkbeetleslivedryouteasilyandcatchfire.

C、Becausebarkbeetlespreventtheearthfromgettingwarmer.

D^Becausebarkbeetlesarecold-bloodedandneedfiretowarmuptheirbodies.

標準答案:B

知識點解析:推斷題。眼據(jù)文章的第一段,氣候變暖導(dǎo)致樹木及土壤水分量減少,

導(dǎo)致火災(zāi)數(shù)量的增多。由此可見問題在于水分的減少。而這種害蟲導(dǎo)致樹木死亡,

死亡的樹木含水量很低,就更容易著火,故選B。

9、Whatkindofchangeshasappearedinthelivingareaofbarkbeetles?

A、Theyaremovingfromthecoolercasttothewarmerwestareas.

B、Theyhavebecomeabletoliveinthehigherareasofthemountains.

C、TheyaremovingfromAlaskatoWyoming.

D^Theyhavecometoliveinthedeadtreesafterwildfires.

標準答案:B

知識點解析:細節(jié)題。由文章的最后一段,“Warmingisalsoexpandingthe

beetles'rangeintohigherakitudes.”可知,因為氣候變暖,地球上高海拔地區(qū)也開始

溫度升高,這樣這種害蟲的生活范圍向上延展,可以在更大的范圍內(nèi)生活,故B

正確。這種擴大是海拔上的,立體的,而不是橫向的,故A、C錯誤。D文中沒有

提及。

10、Whichofthefollowingstatementistrue?

A、Thelifeexpectancyofthebarkbeetlesisbecomingshorter.

B、Globalwarmingdoesn,tinfluencetheearth'sbiologicalsystems.

C>Thenumberofwoodpeckersisrapidlyincreasingbecauseofwarmerwinters.

D、Wecanrelyonbarkbeetlestoindicateglobalclimatechange.

標準答案:D

知識點解析:細節(jié)題。艱據(jù)本文的大意(見第1題解析),A、B和文章的意思相

悖。C中因為暖冬數(shù)量增加的是這種甲蟲,而不是啄木鳥,故錯誤。D這一細節(jié)在

文中結(jié)尾,“thebeetlesseemtobeareliableindicatorofglobalclimatechange''提及

過,故選Do

A、Bypromotinglow-fatversionsofmanypopularfoods.

B、Byforcingthemtopaymoreforcertainkindsoffood.

C、Bydecreasingtheamountofsugarallowedinproducts.

D、Bycreatinglawsconcerninghowmuchpeopleareallowedtoeat.

標準答案:B

知識點解析:細節(jié)題。在很多國家,為了使本國的人民吃得更健康.政府正在準備

增加不健康食物的消費稅,以減少人們對這些食物的購買。本題的答案可以從文章

的第—段得出."'governmentsaretryingtogetcitizenstoeatmorehealthily...Oneway

inwhichgovernmentsaretryingtodothisisbyincreasingtaxesonfoodsthat

areunheakhy.”即促使人們在買這些食物的時候多花錢,故選B。其他三項文中都

沒有提及。

12、DairyfarmersinDenmark.

A^feltthattheywerebeingmadetoproducetoomanyproducts

B、wereworriedthatthegovernmentwasplanningtobancheese

C、arguedthattheirproductsarehealthierthanthegovernmentsaid

D、admittedthattheirproductscontainedanunhealthyamountoffat

標準答案:C

知識點解析:細節(jié)題。該細節(jié)在文章的第二段,^Danishdairyfarmersfeltthatthe

governmentwaswrongtosaythatthefoodstheyproduceareunhealthy.Cheese,for

example,containsalotoffat?butitdoesnotseemtoleadtohealthproblemsinthe

wayotherkindsoffatdo.”即他們認為他們生產(chǎn)的食物不是不健康的.故選C。

13、Whatwasoneresultoftaxingfoodsthathavealotoffat?

A、Manypeopleavoidedpayingthetaxbyshoppingabroad.

B、ManypeoplebeganeatingtraditionalDanishfood.

C、Itmadehealthyfoodslikefruitandvegetablescostmore.

D、ItcausedpeopleinGermanyandSwedentospendlessmoney.

標準答案:A

知識點解析:細節(jié)題。該細節(jié)在文章的第三段,“Sincethesecouldnotbeboughtin

Denmarkatreasonableprices,manyDanishpeoplebeganshoppingin

nearbycouniries.”即他們離不開這些食物,只能去鄰國買這些產(chǎn)品。故A符合題

意。

14、ManyductorslliinkdialtheDanishgovcriiiiicnl.

A、couldhaveendedthetaxonfatsmuchsooner

B、ismoreconcernedaboutmoneythanthehealthofitscitizens

C、hasenoughinformationtoseeiftaxesonunhealthyfoodsareeffective

D、shouldaskothercountriestomakelawsagainstsellingfattyfoods

標準答案:B

知識點解析:細節(jié)題。醫(yī)生的看法可以在文章的最后一段找到,umanydoctorssay

thatoneyearisnotlongenoughtoknowifthetaxhelpedDanish

citizens,health...TheyclaimthattheDanishgovernmentisworriedmoreaboutthe

economythanitisabouttheDanishpeople.”即他們認為政府考慮經(jīng)濟多些,而不是

人民的健康,故與B相符。

15、Whichofthefollowingstatementistrue?

A、Somepeoplethinkthatmakinghealthyfoodscheaperwouldworkbetterthanatax.

B、Healthexpertssaythatweshouldeatmoredairyproductsthanotherfoods.

C、Somekindsoffruitandvegetablesareasunhealthyasmeat.

D、Manypeoplebuyunhealthyfoodstoavoidpayinghightaxes.

標準答案:A

知識點解析:細節(jié)題?!癝uchcriticsbelievethatthegovernmentshouldinsteadtryto

makehealthyfoods,suchasvegetables,cheaper.”即不該多收不健康食物的稅,而

應(yīng)該降低健康食物的價格,故A正確。而文中健康專家說“weneedtoconsidereach

fbodscparatclyandnotsimplyworryabouthowmuchfatitcontains”.并沒有說奶制品

更健康,故B錯誤。文中沒有提到水果和蔬菜不健康,故C錯誤。D與文意相

反,不健康的食物有更高的稅,人們?yōu)榱吮荛_交稅而不會買不健康的食物,故選

A、development

B>evolution

C^cultivation

D^transformation

標準答案:D

知識點解析:詞匯題。通過理解上下文,從相近的詞語中猜測詞義。文中提到了

“mutationorrenewa「故可知renewal便是它的近義詞,意為“突變,演變”,D選項

也表示這個意思,故選D。
