B.Positive.C.Negative. D.Ambiguous.解析:選B觀點(diǎn)態(tài)度題。根據(jù)最后一段可知,機(jī)器人服務(wù)員的技術(shù)改進(jìn)會穩(wěn)步提高,尤其在跟人類交流和開展新活動方面會更好。由此推斷出作者對機(jī)器人服務(wù)員持積極態(tài)度。BChinarecentlycompletedanin-flightconfirmationforsatellitedrag-freecontroltechnology,markingastepforwardinthecountry'sspace-basedgravitationalwave(引力波)detectionprogram.State-ownedChinaAerospaceScienceandTechnologyCorporation(CASC)confirmedthesuccesswiththeTianqin-1,thecountry'sfirstsatelliteforspace-basedgravitationalwavedetection,onSaturday.Drag-freecontroltechnologyblocksforcesthataffectasatellite,excludinggravity,soitcanremainstable,thereportsaid,notingthatforcesneedtobecanceledincludingsunlightpressureandatmosphericdrag.Basedonflightdata,thenewtechnologyreducedexternal(外部的)forcesontheTianqin-1'saccelerationbylessthan1-400millionthofthegravitationalacceleration,markingabetterresultthantheEuropeanSpaceAgency'sGOCEsatellite's1-300millionth.Theresultssuggestthatexternalforceshaveanaccelerationeffectoflessthanahumanyawn,thereportsaid.Moreover,theChinesetechnologywassuccessfulinreducingthedisplacementfromexternalforcesto30nanometers,or1-4,000thofthediameterofanadulthumanhairstrand.Itisalsobetterthantheinternationallywell-knownLISAsatellite's40nanometers,accordingtoScienceandTechnologyDaily.ThetworesultshavesignificanttheoreticalandpracticalvalueindetectingEarth'sgravitationalfield,accordingtothereport.Withthislatestachievement,theTianqin-1hasproventhelevelofitstechnology.TheresearchinstituteunderCASCstartedconductingrelatedresearchin2010,accordingtoScienceandTechnologyDaily,whichalsonotedthatChinastillneedstimetopracticallyapplythetechnologytogravitationalwavedetection.LaunchedonDecember20,2019,theTianqin-1isChina'sfirsttechnologydemonstrationsatelliteintheTianqingravitationalwavedetectionprogram.StartedbytheSunYat-senUniversityin2015,theprogramwilleventuallyconsistofthreesatellitesthatwillformatrianglearoundEarth.語篇解讀:本文是一篇說明文,介紹了“天琴一號”衛(wèi)星上應(yīng)用的無拖拽控制技術(shù),該技術(shù)體現(xiàn)了中國科技的進(jìn)步。5.Whatdoestheunderlinedword“it”inParagraph2referto?A.Gravitationalwavedetection.B.Drag-freecontroltechnology.C.Acertainspacesatellite.D.Sunlightpressure.解析:選C代詞指代題。根據(jù)第二段中的“Drag-freecontroltechnologyblocksforcesthataffectasatellite,excludinggravity,soitcanremainstable”可知,無拖拽控制技術(shù)可以阻止除引力外影響衛(wèi)星的力,因此衛(wèi)星可以保持穩(wěn)定,故畫線詞it指的是“衛(wèi)星”,故C項(xiàng)正確。6.WhatdoestheauthorintendtotellusinParagraph3?A.Ourtechnologyishighlyadvanced.B.TheTianqin-1iswidelyknownworldwide.C.TheLISAsatelliteisatotalsuccess.D.TheTianqin-1'saccelerationisincreased.解析:選A推理判斷題。第三段前半部分說中國的新技術(shù)比歐洲的先進(jìn),無拖拽控制技術(shù)使得外力對加速度的影響比打哈欠給人帶來的加速度的影響還要小,后半部分強(qiáng)調(diào)這一技術(shù)優(yōu)于國際著名的LISA衛(wèi)星應(yīng)用的技術(shù),故本段的主要目的是向讀者展示中國先進(jìn)的科技,故A項(xiàng)正確。7.WhatisTRUEabouttheTianqin-1?A.Itwassentintospacein2015.B.Itguaranteesgreateraccuracywhenworking.C.Itstillneedstimetoremainstable.D.Itcancreategravitationalwaves.解析:選B推理判斷題。根據(jù)第三段最后兩句可知,中國這一技術(shù)(無拖拽控制技術(shù))將外力引起的衛(wèi)星移位控制在了30納米,優(yōu)于國際著名的LISA衛(wèi)星的40納米。由此可推知“天琴一號”在工作時(shí)可以保證較高的準(zhǔn)確性。故B項(xiàng)正確。8.Whereisthispassageprobablytakenfrom?A.Anartmagazine. B.Atravelbrochure.C.Amathematicessay. D.Asciencejournal.解析:選D文章出處題。根據(jù)全文內(nèi)容可知,本文主要介紹了中國航天事業(yè)上的科技進(jìn)步,故本文很有可能選自科學(xué)雜志,故D項(xiàng)正確。Ⅱ.短文改錯DearPeter,Iamwritingtotellyouaabsolutelywonderfulnews.OurschoolphotographyclubistoholdanInternationalStudentPhotographyExhibition,itsthemeisenvironmentalprotection.Theexhibitionwilllastthreeweeks.ThosewhoisinterestedcansignupattheStudentUnion.AsfarasIamconcerned,particularlykeenintakingphotos,youarealwayshavingthedesiredosomethingfortheenvironment.Whichimpressesmemostarethephotosyoutookwhileyouvisitthepark.Whynotshowittoeveryoneattheexhibition?Youcandefinitelymakethedifferent,callingonpeopletodevotethemselvestoprotecttheenvironment.Iwouldbemorethandelightedifyoucouldjoinus.Yours,LiHua答案:第一句:去掉a第二句:its前加and或its→whose第四句:is→are第五句:in→on;desire后加to第六句:Which→What;visit→visited第七句:it→them第八句:different→difference;protect→protectingⅢ.書面表達(dá)假定你是李華,你的英國筆友Peter在給你的郵件中提到他對中國的筷子文化很感興趣,請根據(jù)以下要點(diǎn)給他回一封郵件,簡要介紹中國的筷子文化。1.歷史:3000多年;2.起源于中國,流傳至韓國及日本;3.常用材質(zhì):竹子、木頭;4.推動中國廚藝發(fā)展;5.餐桌禮儀。注意:1.詞數(shù)100左右;2.短文須包括所有提示內(nèi)容;3.可以適當(dāng)增加細(xì)節(jié),以使行文連貫。參考詞匯:烹飪(術(shù))cuisine
