解析：1.考查細(xì)節(jié)理解。根據(jù)Motel6Downtown部分中的"NeighboringtheGoldenGateBridge,it'soneofthemostpopularmotelsinSanFranciscowithenoughfreeparkingspaces"(該旅館毗鄰金門大橋,是舊金山最受歡迎的汽車旅館之一,有足夠的免費(fèi)停車位)可知,想要免費(fèi)停車服務(wù)的游客可以去Motel6Downtown,故A項(xiàng)正確。

2.考查細(xì)節(jié)理解。根據(jù)VanNessInn部分中的"Pricefor1nightperroom:$118fortwoadults,$5foronechild"(每個房間一晚的價格:兩個成人118美元,一個孩子5美元)可知,一對夫婦帶一個孩子住兩晚的價格是(118+5)×2=246美元,故D項(xiàng)正確。

3.考查推理判斷。通讀全文,特別是根據(jù)第一段"IfyouareplanningtotakeatripacrosstheUnitedStates,andareeagerforahotel,herearefoureconomiconesforyoutochoosefrom"(如果你正計劃去美國旅行,并且想人住一家旅館,這里有四家經(jīng)濟(jì)型旅館供你選擇)可知,本文主要介紹的是四家經(jīng)濟(jì)型旅館的相關(guān)信息,據(jù)此可以推知文章的目的應(yīng)是吸引更多的顧客前來入住,故B項(xiàng)正確。B答案：1-4.BCAA

解析：1.考查細(xì)節(jié)理解。根據(jù)第二段中的"It'scrucialthatallitemstakenaboardtheInternationalSpaceStation(ISS)areodorless....alltheirobjectsmustbecheckedbeforeleavingEarth"可知,宇航員離開地球前所攜帶的東西必須經(jīng)過氣味檢查,這是至關(guān)重要的?？臻g站的東西也必須是無味的。可見,氣味檢查是非常嚴(yán)格的。故選B。

2.考查推理判斷。根據(jù)第三段中的"WhentheISSheatsup,aprocesscalledoff-gassingoccurs,whichmeanschemicalsflowoutfromcertainsubstances.ObjectsthatwouldbesafeonEarthcouldgiveoffunpleasantodorsorbecomedangerouswhenexposedtohightemperaturesintheISS'suniqueenvironment"可知,在排氣過程中,地球上安全的物體在國際空間站獨(dú)特的環(huán)境中暴露在高溫下可能會發(fā)出難聞的氣味或變得危險,由此可以推斷這一過程可能對宇航員有害。

3.考查細(xì)節(jié)理解。根據(jù)第四段中的"Ofcourse,humansaren'ttheonlytestersorthefirsttobeexposedtopotentiallydangerousobjects.BeforeAldrichputshisnosenearasubstance,ithasbeenexaminedbymachines"可知,人類并不是唯一也不是首先接觸到可能有危險的物體的測試者,在Aldrich他們工作前會有機(jī)器測試物體。故選A。

4.考查主旨大意。通讀文章可知,本文講述了化學(xué)專家GeorgeAldrich和他的團(tuán)隊(duì)用鼻子來保護(hù)宇航員,使其免受難聞或有害氣味的傷害。他們可以說是不同尋常的氣味測試者。故選A。C答案：1-4.ADAB

解析：1.推理判斷題。本題題干意為:我們對國際空間站的細(xì)菌的了解有哪些?根據(jù)題干中的關(guān)鍵詞bacteriaintheInternationalSpaceStation可定位至第一段。根據(jù)第一段中Bacteriaareanannoyingproblemforastronauts.ThemicroorganismsfromourbodiesgrowuncontrollablyonsurfacesoftheInternationalSpaceStation,soastronautsspendhourscleaningthemupeachweek.可知,國際空間站的細(xì)菌非常難處理,所以選擇A項(xiàng)。B:它們導(dǎo)致空氣污染;C:它們以不同的形式出現(xiàn);D:它們毀壞儀器。

2.細(xì)節(jié)理解題。本題題干意為:HUNCH項(xiàng)目的目的是什么?第二段第一句HUNCHisdesignedtoconnecthighschoolclassroomswithNASAengineers.(HUNCH的設(shè)計目的是將高中教室與NASA的工程師聯(lián)系在一起。)中的highschoolclassrooms與D選項(xiàng)中的schooleducation(學(xué)校教育)對應(yīng),NASAengineers與D選項(xiàng)中的spacetechnology(空間技術(shù))對應(yīng),故選D。A:為了加強(qiáng)師生關(guān)系;B:為了提升學(xué)生的交流技能;C:為了讓學(xué)生體驗(yàn)失重。

3.推理判斷題。本題題干意為:NASA的工程師為參加此項(xiàng)目的學(xué)生做了些什么?根據(jù)題干中的NASAengineersdo可定位至第三段的Engineerscomeandreallydoanin-personreview,and...it'snotaverynicethingattimes.It'sahardbusinessreviewofyourproduct,句中兩次出現(xiàn)review(檢查,審查),證明NASA的工程師做的事情就是對學(xué)生做出的研究結(jié)果進(jìn)行檢查,所以答案是A項(xiàng)。B:指導(dǎo)項(xiàng)目設(shè)計;C:調(diào)整工作時間表;D:給他們的作業(yè)打分。

4.主旨大意題。本題題干意為:最適合本文的標(biāo)題是什么?本文主要介紹HUNCH項(xiàng)目,這個項(xiàng)目是有關(guān)太空研究的,而且研究者都是高中生。根據(jù)以上要點(diǎn)可知,最佳選項(xiàng)是B項(xiàng)(Space:TheFinalHomeworkFrontier),Space對應(yīng)太空研究,Homework對應(yīng)高中教育,Frontier(前沿)突出了這個項(xiàng)目的領(lǐng)先性。D答案：1-4.BCDA

解析：1.考查推理判斷。根據(jù)第一段內(nèi)容可知,他過去的項(xiàng)目包括凈化空氣的霧霾凈化塔和光之門等,由此可知,DaanRoosegarde在解決環(huán)境問題上很有創(chuàng)造力,故B項(xiàng)正確。

2.考查細(xì)節(jié)理解。根據(jù)第二段中的"Theexperiencewasdesignedtomakethepublicknowmoreabouthowmuchspacejunkthereis"可知,舉辦這個激光秀的目的是增加公眾對太空垃圾數(shù)量的了解,故C項(xiàng)正確。

3.考查詞義猜測。根據(jù)畫線詞后的"ifsuccessful,burningspacetrashcouldsomedayreplacefireworksatlargepublicevents"可知,DaanRoosegarde設(shè)想如果成功的話,焚燒太空垃圾有一天會取代大型公共活動中的煙火,由此可知,畫線詞意為"設(shè)想,想象",故D項(xiàng)正確。

4.考查細(xì)節(jié)理解。根據(jù)最后一段內(nèi)容可知,帆的作用是在任務(wù)結(jié)束時將衛(wèi)星帶入到大氣層中自動毀滅,故A項(xiàng)正確。第二節(jié)答案：BGDAF

解析：如何調(diào)整睡眠周期,有一個好的睡眠呢?請看作者告訴了你哪些方法!①上文提到"Eatbreakfastlikeaking,lunchlikeaprinceanddinnerlikeapoorman"是人們常說的有關(guān)一日三餐的諺語,與B項(xiàng)中的Thissaying相對應(yīng),故選B項(xiàng)。②上文提到"早起"的前提是"早睡",立刻入睡可能不容易,需要一些放松的程序來達(dá)到目的,故選G。③本段主要講的是室內(nèi)光線要適合睡眠,D項(xiàng)的內(nèi)容"Switchofflaptopsandothersourcesoflightinyourbedroom"與此一致,要關(guān)掉筆記本電腦和臥室的其他光源。④該段主要講了要保持有規(guī)律的睡眠時間,周六允許多睡一個小時,但周日必須恢復(fù)過來,故選A項(xiàng)。⑤該段主題是停止擊打止鬧按鈕,F項(xiàng)"最有效的方法是將鬧鐘放到房間的另一端"與下文內(nèi)容聯(lián)系緊密,當(dāng)鬧鐘響的時候,你必須起床找鬧鐘并將鬧鈴關(guān)掉,這樣就能準(zhǔn)時起床了。第二部分語言知識運(yùn)用第一節(jié)答案：1-5.BACDD;6-10.BCCBD;11-15.ADBCB

解析：1.根據(jù)上文中的"someprettyamazingthings"及下文中的"inzerogravity"可知,B項(xiàng)符合語境。

2.根據(jù)常識和語境可知,這里是說沒有重力,宇航員有很多事情不能做。

3.根據(jù)語境可知,在沒有重力的情況下,宇航員不能做很多事情,這是很令人難過的。sad"讓人難過的"符合語境。下文中的sadness也是信息提示。

4.根據(jù)上文中的"lettheirsadnessshow"和下文中的關(guān)鍵詞tears及crying可知,應(yīng)選D項(xiàng)。

5.根據(jù)常識可知,在太空中沒有重力。weightless"失重的"符合語境。

6.根據(jù)語境可知,此處表示"這意味著當(dāng)你在太空中哭泣時,你的眼淚無處可去",故B項(xiàng)符合語境。

7.由上文中的"yourtearshavenowheretogo"可知,此處表示眼淚只會停留在眼眶里,故選C項(xiàng)。

8.根據(jù)下文中的"Myrighteyeispainfullikecrazy"可知,2011年5月,宇航員AndrewJ.Feustel在太空中就經(jīng)歷過這樣痛苦的事。experience"經(jīng)歷"符合語境。
