【答案】1.A2.B3.C

【解析】

這是一篇應(yīng)用文。文章是?篇關(guān)于能夠帶入英國物品的說明，包括可以帶入的物品、要被征

稅的物品和煙酒類產(chǎn)品的起征額度等信息。

【1題詳解】

細(xì)節(jié)理解題。根據(jù)Alcohol&tobaccoallowance表格中“Beer：16litres（啤酒:16升理

是所有商品中數(shù)額最大的，故“啤酒”這種來自歐盟以外的產(chǎn)品有最大的免稅額度。故選A。

【2題詳解】

細(xì)節(jié)理解題。根據(jù)"Therateofdutyortaxonitemsabovetheallowanceis:92.5%

forgoodsworthupto￡630（超過免稅額的物品的稅率為：?630英鎊以下的商品價格為

2.5%）”可知，一個來自中國的人在美國買一枚價值500英鎊的戒指要交稅500*2.5%=12.5

英鎊。故選B。

【3題詳解】

細(xì)節(jié)理解題。根據(jù)“Goodsbannedinclude:?meatanddairyproductsfrommostnon-EU

countries.（禁止的商品包括：來自大多數(shù)非歐盟國家的肉類和奶制品）”可知，澳大利亞奶

酪磚會被禁止帶入。故選C。

【答案】4.C5.A6.D7,C

【解析】

這是一篇記敘文。文章講述了鄉(xiāng)村醫(yī)生Cortez針對村民感染新冠病毒的現(xiàn)狀，結(jié)合國家疫

情防控形勢和村子的地理特征，果斷采取措施，降低村民感染率的故事。

【4題詳解】

推理判斷題。由第一段內(nèi)容尤其是最后一句"Adoctororderedhisfamilytoburyhim

quickly,againstPhilippinetradition,andalleightpeoplewholivedwithhimwere

putundera14-dayquarantine（隔離）intheircrowdedhome.n可知，Cortez依據(jù)死

者的死亡檢查報告和疫情情況，迅速做出反應(yīng)并立即對死者的家人采取隔離措施。由此可推

知，Cortez展現(xiàn)出了他的職業(yè)敏感性。故選C項。

【5題詳解】

細(xì)節(jié)理解題。由第四段最后兩句"CortezandBalgosaresharplyawareofthethreatthe

virusposestoBambang,whichsitsinavalleysurroundedbymountains.Anyonegoing

southtoManilaornorthtowardtherestofthecountryendsuppassingthrough

Bambang.M可知，Bambang地處交通要道，Cortez意識到疫情可能會對它產(chǎn)生影響，決定采

取嚴(yán)格的防控措施。故選A項。

【6題詳解】

推理判斷題。由倒數(shù)第二段最后兩句"Anyonewithsymptomswouldbemovedtoacenter

setupinthemountains.Sofarthatcenterhasremainedempty."可知，任何出現(xiàn)

了癥狀的人都會被送往山區(qū)的隔離點，而現(xiàn)在山區(qū)的隔離點還沒有人。由此可推知，Cortez

建立的接觸追蹤系統(tǒng)是有效的。故選D項。

【7題詳解】

推理判斷題。通讀全文可知，文章講述了鄉(xiāng)村醫(yī)生Cortez投身于新冠病毒防控的故事。由

此可推知，本文很有可能選自雜志。故選C項。

【答案】8.D9.D10.B11.C

【解析】

這是一篇說明文。文章講述科學(xué)家們通過研究發(fā)現(xiàn)石墨烯制成的衣服在應(yīng)對蚊蟲叮咬方面有

一定的效果。

【8題詳解】

細(xì)節(jié)理解題。根據(jù)第二段“Itwouldbegreatifclothingcouldbeusedtocompletely

preventpeoplefromgettingbitten.Researcherstestedgraphene（石墨烯），amaterial

thatisincrediblythinbutreallystrong,inordertofindoutifitcanmakeclothing

resistanttomosquitoes.（如果衣服能完全防止人們被咬，那就太好了。研究人員測試了

石墨烯，一種非常薄但非常結(jié)實的材料，以確定它是否能使衣服抵抗蚊子。）”可知，研究

者做這個實驗的目的是測試石墨烯預(yù)防蚊蟲叮咬的有效性。故選Do

【9題詳解】

詞義猜測題。根據(jù)劃線單詞所在句"Avideocamerawasthenusedtorecordandquantify

mosquitoes'behavior,includingwhethertheylandedontheskin,howlongtheystayed

there,andwhethertheybegantodrawblood（然后用一臺攝像機記錄和量化蚊子的行

為，包括它們是否落在皮膚上，停留多長時間，以及它們是否開始吸血。）和常識可知，蚊

子停留在人的皮膚上目的就是吸血，由此可知，此處〃draw〃的意思是suck“吸”。故選D。

【10題詳解】

推理判斷題。根據(jù)最后一段"Asaresult,thenumberofmosquitobitesonnakedskin

wasthehighest,about16onaverage;skinonlyprotectedbycheeseclothgotthe

second,approximately10perfiveminutes'exposure.（結(jié)果，蚊子叮咬裸露皮膚的

次數(shù)最多，平均約16次;只有粗棉布保護的皮膚得到第二，大約每5分鐘10次。）和“The

mosquitoeslandedonskintotallyuncoveredorcoveredincheeseclothabout23times

onaverage,andstayedforonetotwominutes.（這些蚊子平均有23次降落在沒有遮

蓋的皮膚上，或者被紗布覆蓋，停留1到2分鐘。）”可推知，研究者們通過比較數(shù)據(jù)得出

結(jié)論的。故選B。

【11題詳解】

推理判斷題。根據(jù)第二段“Itwouldbegreatifclothingcouldbeusedtocompletely

preventpeoplefromgettingbitten.（如果衣服能被用來完全防止人們被叮咬，那就太

好了o）”和最后一段“Butfortunately,thenumberofmosquitobitesineitherdry

orwetconditionscanbeloweredaslongasthegraphenematerialisimprovedto

acertainextent.（但幸運的是，只要石墨烯材料在一定程度上得到改善，無論是干燥還

是潮濕條件下，蚊子叮咬的次數(shù)都可以降低。）”可得知，本文通過先提出假設(shè)再得出結(jié)論

的方式來介紹本文內(nèi)容的。故選C。

這是一篇新聞報道。主要說明了中國科學(xué)家已經(jīng)使用激光精確識別了地球軌道上空間碎

片。文章對這項技術(shù)進行了簡單說明，介紹了軌道碎片的相關(guān)知識以及這項研究的一些背景

知識。

【12題詳解】

細(xì)節(jié)理解題。根據(jù)第二段“Theteamappliedaspeciallydevelopedsetofrulesto

【答案】16.C17.E18.G19.B20.D

【解析】

【分析】本文是說明文。短文介紹了了如何祝賀別人的三個技巧。

【詳解】1.根據(jù)選項位置以及第二段中“Whenthereissomethingtocelebrate,don，t

skirtaroundtheissue.n當(dāng)有什么值得慶祝的時候，不耍回避這個問題?？芍?，在有值

得慶祝的事情時、不要回避話題，即我們要提出這個話題。選項C."Bringupthesubject"

提起話題，可以概括本段。故選C。

2.根據(jù)前文“Explainwhyyoucongratulatethepersonrightoffthebat.”解釋一

下你為什么要馬上祝賀那個人。選項E.“Youcanalsotellhimorherhowyouheardthe

newsifnecessary.”如果有必要，你也可以告訴他或她，你是怎么聽到這個消息的。是對

上文的解釋，故選E。

3.根據(jù)前文“Expresshowyoufeelaboutthesubject.v表達你對這個話題的感受?？?/p>

知，接下來為闡述你對這件事情的感受。選項G.“Youcanfurtherconveyyourfeelings

appropriatelyaftersaying"congratulations.”你可以在說完“恭喜”之后，再進一

步表達你的感受。是對前文的補充和延續(xù)，符合文意，故選G。

4.上文提到“Rememberthatyourtoneofvoicecanreallycarryweight”記住你的語

氣要有分量，所以在表達情感時要注意語氣，盡量表現(xiàn)出來，選項B.“Beasexpressiveas

youcan.”盡可能的表現(xiàn)出來。符合文意，故選B。

5.結(jié)合上文提至！JuSurelytherewillbemomentswhenyourcomplimentsarenotgiven

fromthebottomofyourheart.”當(dāng)然，有些時候你的贊美不是發(fā)自內(nèi)心的選項與上文為

轉(zhuǎn)折關(guān)系。選項D.“Butyou'dbetterbeasgenerousaspossible."但你最好盡量慷

慨一點。呼應(yīng)主題句“盡量使你的祝賀真誠”。故選D。
