wittobeusedinremoteorresource-limitedplaceslikesmallislands,ships,andevenforemergencyuse．(大多數(shù)商業(yè)上可用的便攜式海水脫鹽裝置使用的過濾器需要高壓泵來推動(dòng)水，這使得它們體積龐大，能源效率較低。這種無過濾器的MIT設(shè)備可以在偏遠(yuǎn)或資源有限的地方使用，比如小島、船只，甚至是緊急情況下使用。)”可知，第三段主要通過對(duì)比新的脫鹽設(shè)備和其他商業(yè)上可用的便攜式脫鹽設(shè)備來說明新設(shè)備的優(yōu)勢。故選A。7．C細(xì)節(jié)理解題。根據(jù)倒數(shù)第二段“Butbestofall,itisdesignedtobeusedbyaveragepeopleandnotengineers．(但最重要的是，它是為普通人而不是工程師設(shè)計(jì)的。)”可知，作者認(rèn)為這個(gè)新設(shè)備最突出的優(yōu)點(diǎn)是普通人也可以輕松操作。故選C。8．D標(biāo)題歸納題。通讀全文可知，文章主要介紹了一款新的即將面市的便攜式海水脫鹽設(shè)備，它操作方便，體積雖小但功能強(qiáng)大，普通人也能使用，可以為我們?nèi)彼氖澜鐜戆踩捎玫?。由此可知，D項(xiàng)“新的便攜式設(shè)備即將使海水可以飲用”符合文章大意，適合作為文章標(biāo)題。故選D。C(2023·廣東省梅州市高三二模)Artandsciencemayseemlikeoppositethings．Onemeansthecreativeflowofideas,andtheothermeanscold,harddata—somepeoplebelieve．Infact,thetwohavemuchincommon．Now,astudyfindsartcanhelpstudentsrememberbetterwhattheylearnedinscienceclass．MarialeHardiman,aneducationspecialistatJohnsHopkinsUniversity,noticedthatstudentswhousedartintheclassroomlistenedmorecarefully．Theymightaskmorequestions．Theymightvolunteermoreideas．What'smore,studentsseemedtoremembermoreofwhattheyhadbeentaughtwhentheirsciencelessonshadinvolved(涉及)art．Toprovethat,Hardimanteamedupwithsomeresearchersandsixlocalschools．Intheexperiment,theresearchersworkedwithteachersin16fifth-gradeclassrooms．Theyprovidedtraditionalsciencelessonsandart-focusedones．Inatraditionalscienceclass,forexample,studentsmightreadaloudfromabook．Intheart-focusedone,theymightsingtheinformationinstead．Theteamrandomlyassigned(隨機(jī)分配)eachofthe350studentstoeitheratraditionalscienceclassroomoranart-focusedone．Studentsthenlearnedscienceusingthatwayforthewholeunit—aboutthreeweeks．Whentheychangedtoanewtopic,theyalsochangedtotheothertypeofclass．Thisway,eachstudenthadbothanart-focusedclassandatraditionalone．Everyunitwastaughtinbothways,todifferentgroupsofstudents．Thisenabledtheresearcherstoseehowstudentsdidinbothtypesofclasses．Theteamfoundthatstudentswhostartedoffintraditionalclassesperformedbetteraftertheymovedintoanart-focusedclass．Butthosewhostartedinanart-focusedclassdidwellevenwhentheywentbacktoatraditionalscienceclass．Thesestudentsappearedtousesomeofthearttechniques(技巧)aftergoingbacktoatraditionalclass．Classroomteachersreportedthatmanystudentscontinuedtosingthesongsthattheylearnedafterfinishingtheunit．“Themorewehearsomething,themoreweretainit，”Hardimansays．“Itsuggeststhattheartsmayhelpstudentsapplycreativewaysoflearningontheirown．”9．WhydidMarialeHardimandothestudy？A．Toprovetheimportanceofartatschool．B．Toknowhowtoencouragestudentstoaskquestions．C．Tofindawaytohelpherstudentslearnbetter．D．Toseeifartmightimprovesciencelearning．10．Whatwerethestudentsrequiredtodointheexperiment？A．Learnthreeunitsintotal．B．Choosewhatthey'dliketolearn．C．Learntwotopicsforthreeweeks．D．Taketwotypesofclasses．11．Whatdoestheunderlinedword“retain”inthelastparagraphmean？A．Remember．
