A.helptoupdateputersystemsB.linkthehumanbrainwithputersC.helpthedisabledtorecoverD.controlaperson’sthoughts答案B解析細(xì)節(jié)理解題。根據(jù)第一段可知,自20世紀(jì)70年代以來,科學(xué)家一直尋找途徑能將人腦與電腦相連。BCI技術(shù)能幫助殘疾人向機(jī)器發(fā)送指令。故此處B項(xiàng)正確。而C項(xiàng)只是部分正確,雖然能幫助殘疾人,但卻不能幫他們康復(fù)。6.HowdidTavellaoperatethewheelchairinthelaboratory?A.Bycontrollinghismuscles.B.Bytalkingtothemachine.C.Bymovinghishand.D.Byusinghismind.答案D解析細(xì)節(jié)理解題。根據(jù)第三段可知Tavella只是思考動(dòng)他的左右手就能操作這個(gè)輪椅。甚至當(dāng)他觀察這臺(tái)機(jī)器時(shí)就能進(jìn)行交流,也能用他的思想指導(dǎo)機(jī)器人工作。因此機(jī)器人是在人腦的思想支配下進(jìn)行工作的。故D項(xiàng)正確。7.Theteamwilltestwithrealpatientsto.

A.makeprofitsfromthemB.provethetechnologyusefultothemC.makethemlivelongerD.learnabouttheirphysicalcondition答案B解析推理判斷題。根據(jù)最后一段第二句“Oneistestingwithrealpatients,soastoprovethatthisisatechnologytheycanbenefitfrom.”可知,在患者身上進(jìn)行實(shí)驗(yàn)是他們團(tuán)隊(duì)工作的一個(gè)目標(biāo),旨在證明這項(xiàng)技術(shù)對他們有益。故答案選B項(xiàng)。8.Whichofthefollowingwouldbethebesttitleforthetext?A.Switzerland,theBCIResearchCentreB.NewFindingsaboutHowtheHumanBrainWorksC.BCICouldMeanMoreFreedomfortheDisabledD.RoboticVehiclesCouldHelptoCureBrainInjuries答案C解析主旨大意題。本文為科技說明文,開篇點(diǎn)題。介紹科學(xué)家研究的這項(xiàng)新技術(shù)BCI,對殘疾人大有裨益。故答案為C項(xiàng)。四、七選五閱讀理解(2020·全國Ⅰ)AFewTipsforSelfAcceptanceWeallwantit...toacceptandloveourselves.Butattimesitseemstoodifficultandtoofaroutofreach.1Here’sahandfulofwaysthatwillsetyouintherightdirection.
