托福閱讀事實(shí)信息題考點(diǎn)及應(yīng)對策略
46 2017-07-20
<1>提問方式
1.AccordingtoParagraph…,whichofthefollowingistrueaboutX?
2.AccordingtoParagraph…,how/what/why…?
3.Paragraph…/ThepassagesupportswhichofthefollowingstatementsaboutX?
朗閣海外考試研究中心的專家認(rèn)為帶有提問方式的題型可以總結(jié)為以下幾個(gè)特點(diǎn):
a.該題型屬于細(xì)節(jié)類題型,并且在大部分情況下題干中會出現(xiàn)一個(gè)明確的細(xì)節(jié)定位詞───X。
b.該題型是對細(xì)節(jié)信息的正面提問(由題干中true/support可知),這一點(diǎn)與否定事實(shí)信息題相反。
c.該題型疑問部分一般由特殊疑問詞:which/how/what/why…引導(dǎo),可以得出該題型可以就某細(xì)節(jié)信息的具體“特性、原因、方式等”進(jìn)行發(fā)問。
<2>解題步驟:
第一步:讀題干,劃出定位詞。
定位詞特點(diǎn):
a.在提問方式1和3當(dāng)中就是X所代表的部分。
b.在提問方式2中比較復(fù)雜,一般是尋找該句中的名詞部分,多數(shù)充當(dāng)句中的主語或賓語。
c.定位詞有可能是原文原詞或者近義詞。
例題:
1.Accordingtoparagraph6,whichofthefollowingstatementsaboutaquifersindesertsistrue?(TPO12WaterintheDesert)
本題干的定位詞即aquifers,符合提問方式1。
2.Accordingtoparagraph7,whywouldasocialgroupuseshunning?(TPO13TypesofSocialGroups)
本題干的定位詞即shunning,符合提問方式2。
3.Paragraph1supportswhichofthefollowingstatementsaboutpaintinginEurope?(TPO4CaveArtinEurope)
本題干的定位詞即是paintinginEurope,符合提問方式3。
第二步:根據(jù)定位詞回原文進(jìn)行定位。
注意:
1.若定位詞非原文原詞,在定位過程中要對其在原文中的同義替換詞敏感。
2.若定位詞在原文中出現(xiàn)若干次,要關(guān)注所有出現(xiàn)過的地方。
例題:
Paragraph3:Thesubjectsofthepaintingsaremostlyanimals.Thepaintingsrestonbarewalls,withnobackdropsorenvironmentaltrappings.Perhaps,likemanycontemporarypeoples,UpperPaleolithicmenandwomenbelievedthatthedrawingofahumanimagecouldcausedeathorinjury,andifthatwereindeedtheirbelief,itmightexplainwhyhumanfiguresarerarelydepictedincaveart.Anotherexplanationforthefocusonanimalsmightbethatthesepeoplesoughttoimprovetheirluckathunting.Thistheoryissuggestedbyevidenceofchipsinthepaintedfigures,perhapsmadebyspearsthrownatthedrawings.Butifimprovingtheirhuntingluckwasthechiefmotivationforthepaintings,itisdifficulttoexplainwhyonlyafewshowsignsofhavingbeenspeared.Perhapsthepaintingswereinspiredbytheneedtoincreasethesupplyofanimals.CaveartseemstohavereachedapeaktowardtheendoftheUpperPaleolithicperiod,whentheherdsofgameweredecreasing.(TPO4:CaveArtinEurope)
Accordingtoparagraph3,scholarsexplainedchipsinthepaintedfiguresofanimalsbyproposingthat______○UpperPaleolithicartistsusedmarkstorecordtheanimalstheyhadseen.
○Thepaintingswereinspiredbytheneedtoincreasethesupplyofanimalsforhunting.
○Theartistshadremovedroughspotsonthecavewalls.
○UpperPaleolithicpeopleusedthepaintingstoincreasetheirluckathunting.
解題步驟:
1.讀題干,找出定位詞chips
2.根據(jù)定位詞回原文進(jìn)行定位,發(fā)現(xiàn)在原文中只有一處出現(xiàn)了chips的原詞。那么暫且將答案鎖定在該句。
Paragraph6:Allthisapplies,ofcourse,onlytoanadultleatherback.Hatchlingsaresimplytoosmalltoconservebodyheat,evenwithinsulationandcountercurrentexchangesystems.Wedonotknowhowold,orhowlarge,aleatherbackhastobebeforeitcanswitchfromacold-bloodedtoawarm-bloodedmodeoflife.Leatherbacksreachtheirimmensesizeinamuchshortertimethanittakesotherseaturtlestogrow.Perhapstheirrushtoadulthoodisdrivenbyasimpleneedtokeepwarm.(TPO15:AWarm-bloodedTurtle)
11.Accordingtoparagraph6,whichofthefollowingstatementsismostaccurateaboutyoungleatherbackturtles?○Theylackthecountercurrentexchangesystemsthatdevelopinadulthood.
○Theirrateofgrowthisslowerthanthatofotherseaturtles.
○Theyloseheateasilyevenwithinsulationandcountercurrentexchangesystems.
○Theyswitchbetweencold-bloodedandwarm-bloodedmodesthroughouttheirhatchlingstage
解題步驟:
1.讀題干,劃出定位詞youngleatherbackturtles
2.根據(jù)定位詞回原文進(jìn)行定位,在原文中并不能找到原文原詞。因此,考慮有可能是近義詞,進(jìn)而發(fā)現(xiàn)youngleatherbackturtles的同義替換詞hatchlings。
(點(diǎn)評:該題的難點(diǎn)就在于定位,考生必須要對同義替換詞非常熟悉)
Paragraph6:Groundwaterisstoredintheporespacesandjointsofrocksandunconsolidated(unsolidified)sedimentsorintheopeningswidenedthroughfracturesandweathering.Thewater-saturatedrockorsedimentisknownasan"aquifer".Becausetheyareporous,sedimentaryrocks,suchassandstonesandconglomerates,areimportantpotentialsourcesofgroundwater.Largequantitiesofwatermayalsobestoredinlimestoneswhenjointsandcrackshavebeenenlargedtoformcavities.Mostlimestoneandsandstoneaquifersaredeepandextensivebutmaycontaingroundwatersthatarenotbeingrecharged.Mostshallowaquifersinsandandgraveldepositsproduceloweryields,buttheycanberapidlyrecharged.Somedeepaquifersareknownas"fossilwaters.Theterm"fossil"describeswaterthathasbeenpresentforseveralthousandyears.Theseaquifersbecamesaturatedmorethan10,000yearsagoandarenolongerbeingrecharged.(TPO12:WaterintheDesert)
8.Accordingtoparagraph6,whichofthefollowingstatementsaboutaquifersindesertsistrue?
○Waterfromlimestoneandsandstoneaquifersisgenerallybettertodrinkthanwaterfromsandandgravelaquifers
○Sandandgravelaquiferstendtocontainlessgroundwaterthanlimestoneorsandstoneaquifers
○Groundwaterindeepaquifersismorelikelytoberechargedthangroundwaterinshallowaquifers
○Sedimentaryrocks,becausetheyareporous,arenotcapableofstoringlargeamountsofgroundwater
解題步驟:
1.讀題干,找出定位詞aquifersindeserts
2.根據(jù)定位詞回原文進(jìn)行定位,在原文中找到了aquifers的原文原詞,但問題是出現(xiàn)了五次。
(點(diǎn)評:該題的難點(diǎn)不在于尋找定位詞,而在于定位詞出現(xiàn)次數(shù)過多,因此考生此時(shí)需要看的范圍非常大,對于考生篩選信息的能力要求比較高。)
第三步:比較定位句和選項(xiàng),篩選出和原文信息匹配的選項(xiàng)。
注意:
1.大多數(shù)情況下答案就在定位詞所在的句子里,但有時(shí)也有可能位于定位句的上一句或下一句。
2.考生只需要核對定位句的信息和選項(xiàng)里的信息是否吻合即可,不需要推理。
3.該題型對于考生的長難句分析能力要求比較高,因?yàn)橥ㄎ痪涠际墙Y(jié)構(gòu)上比較復(fù)雜的句子。
例題:
Paragraph4:Nomadismalsosubjectspastoralistmunitiestostrictrulesofportability.Ifyouareconstantlyonthemove,youcannotaffordtoaccumulatelargematerialsurpluses.Suchruleslimitvariationsinaccumulatedmaterialgoodsbetweenpastoralisthouseholds(thoughtheymayalsoencourageatasteforportablegoodsofhighvaluesuchassilksorjewelry).So,byandlarge,nomadismimpliesahighdegreeofself-sufficiencyandinhibitstheappearanceofanextensivedivisionoflabor.Inequalitiesofwealthandrankcertainlyexist,andhaveprobablyexistedinmostpastoralistsocieties,butexceptinperiodsofmilitaryconquest,theyarenormallytooslighttogeneratethestable,hereditaryhierarchiesthatareusuallyimpliedbytheuseofthetermclass.Inequalitiesofgenderhavealsoexistedinpastoralistsocieties,buttheyseemtohavebeensoftenedbytheabsenceofsteephierarchiesofwealthinmostmunities,andalsobytherequirementthatwomenacquiremostoftheskillsofmen,including,often,theirmilitaryskills.(TPO14:PastoralisminAncientInnerEurasia)
9.Accordingtoparagraph4,thefactthatpastoralistmunitiesaresubjectto“strictrulesofportability”encouragessuchmunitiesto
○relocatelessfrequentlythantheywouldotherwise
○havehouseholdsthataremoreorlessequalinwealth
○beself-sufficientinthemanufactureofsilkandjewelry
○sharelargematerialsurpluseswithneighboringmunities
解題步驟:
1.讀題干,尋找定位詞,即題干部分已經(jīng)標(biāo)記陰影的strictrulesofportability。
2.根據(jù)定位詞回原文進(jìn)行定位,很容易發(fā)現(xiàn)定位詞所在的句子即是第一句。但仔細(xì)閱讀發(fā)現(xiàn)本句話并不是答案。因?yàn)轭}目是想問某個(gè)現(xiàn)象的影響,而第一句話只是在描述這個(gè)現(xiàn)象。那么只有繼續(xù)往下看,發(fā)現(xiàn)第三句話Suchruleslimit…可以推斷這里的代詞suchrules應(yīng)該指代的定位詞strictrulesofportability,而且仔細(xì)閱讀該句話的意思也是在說明某件事的影響。
3.比較定位句與選項(xiàng):
定位句:Suchruleslimitvariationsinaccumulatedmaterialgoodsbetweenpastoralisthouseholds.大致意思說:“這樣的條例會限制不同游牧家庭之間所收集的產(chǎn)品的差別”。
選項(xiàng)A談到relocate定居,不符合該句話;B選項(xiàng)moreorlessequalinwealth就等同于limitvariationsinaccumulatedmaterialgoods;C選項(xiàng)self-sufficient自滿自足的,不符合原文;D選項(xiàng)sharelargematerialsurplus共享剩余產(chǎn)品資料,不符合原文。
點(diǎn)評:
該題的主要難點(diǎn)在于定位詞所在句并不是答案,考察考生在更大范圍內(nèi)搜索答案。在考試時(shí)間比較緊張的情況之下,非常考察一個(gè)考生的沉著冷靜。
Paragraph1:Petroleum,consistingofcrudeoilandnaturalgas,seemstooriginatefromorganicmatterinmarinesediment.Microscopicorganismssettletotheseafloorandaccumulateinmarinemud.Theorganicmattermaypartiallydpose,usingupthedissolvedoxygeninthesediment.Assoonastheoxygenisgone,decaystopsandtheremainingorganicmatterispreserved.
2.Accordingtoparagraph1,whichofthefollowingistrueaboutpetroleumformation?
○Microscopicorganismsthatliveinmudproducecrudeoilandnaturalgas.
○Largeamountsofoxygenareneededforpetroleumformationtobegin.
○Petroleumisproducedwhenorganicmaterialinsedimentsbineswithdecayingmarineorganisms.
○Petroleumformationappearstobegininmarinesedimentswhereorganicmatterispresent.
解題步驟:
1.讀題干,找到定位詞petroleumformation;
2.根據(jù)定位詞回原文進(jìn)行定位,沒有發(fā)現(xiàn)定位詞,并且通段都是在介紹petroleum是如何形成的。所以,此時(shí)只能通讀整段,結(jié)合排除法對選項(xiàng)一一排除。
3.選項(xiàng)A微生物microscopicorganism能夠制造出原油crudeoil和天然氣,不符合原文。因?yàn)楦鶕?jù)文章,石油的形成主要來自于有機(jī)物organicmatter,而微生物microscopicorganism只是起到一個(gè)幫助前者分解的作用。因此要排除A。選項(xiàng)B考點(diǎn)詞為Largeamountsofoxygen,原文并沒有提到具體需要的氧氣量。選項(xiàng)Corganicmaterial與marineorganisms結(jié)合形成石油,不符合原文,因?yàn)閼?yīng)該是有機(jī)物organicmatter和微生物microscopicorganism結(jié)合。選項(xiàng)D符合原文,與原文第一句話Petroleum,consistingofcrudeoilandnaturalgas,seemstooriginatefromorganicmatterinmarinesediment的意思符合。其中同義替換部分為originatefrom=begin。
點(diǎn)評:
該題的主要難點(diǎn)在于定位詞不夠specific,不夠獨(dú)特。當(dāng)該題型給出的定位詞整個(gè)通段都在描述相關(guān)信息的時(shí)候,那么考生極有可能需要通段瀏覽,且只能用排除法一一進(jìn)行排除。
小結(jié):
綜上所述,可以言簡意賅地說事實(shí)信息題主要考察考生的兩種能力:定位&同義轉(zhuǎn)換。朗閣海外考試研究中心的專家認(rèn)為考生可以沿著這兩個(gè)方向去備考,另外建議廣大考生先學(xué)習(xí)詞匯題和句子簡化題,然后再學(xué)習(xí)事實(shí)信息題。
