文章是一篇说明文。文章主要介绍了Nuro自主设计的一种自动驾驶汽车。此自动驾驶汽车被用来递送货物,并有着广阔的前景。1.D细节理解题。根据文章第一段中“Theelectriccarfeaturesfourexteriorcompartments(隔层) twooneachside toholdseparatedeliveries.”可知,Nuro的自动驾驶汽车的主要特征是它的运送可以在特殊的隔层里运输,故选D。2.C词义猜测题。根据第四段第二句“FullyautonomousvehicleswithoutatestdriverarentlegalinCaliforniatoday,andmanycompanieshaveshiftedtestingtostateswhereregulatorsaremorewelcomingofautonomousvehicles,suchasArizona.”可知,在加利福尼亚没有驾照驾驶全自动交通工具是不合法的,由此可推知hurdle意为“限制”,故选C。3.B细节理解题。根据倒数第二段第五句“Fergusonsaidhisteamhadconductedstudiesandfoundthatsuchtechniquescouldconfusepeople.”可知,这样的技术可能会使人困惑,故选B。4.A观点态度题。根据文章最后一段Ferguson 的话“Thisisnotswappingjobswithrobots.Itscreatingnewmarkets.Therewilldefinitelybenewemploymentopportunities.”可知这样的新技术增加了新的就业机会,据此推测Ferguson认为这样的新技术是有益的,故选A。.【文章大意】 本文是一篇说明文。文章主要介绍了一个用来诊断疾病的手机应用软件。1.F承接上文“Imaginethatyouareinaremotevillagesomewherewithnomedicalclinic.”,并结合常识可知,在一个没有医疗诊所的偏远村庄,病得很重的情况下,只能等数日才能得到医疗救助,故选F。2.B承接上文“Oncethedoctorsgettoyou,theyexamineyouandtakebloodsamples,buttheywontbeabletohelpyouuntiltheytakethesamplesbacktothehospitaltofindoutwhatiswrong.”可知,医生要先检查,采集血样,无法立即提供帮助,可推知,患者的治疗可能会被耽误,故选B。3.G承接上文“Manydoctors,forexample,donthaveenoughtrainingtocorrectlyinterpretwhattheysee.”可知,许多医生因为没有足够的训练而不能正确地进行诊断,由此会误诊,故选G。4.A承接上文“Qzcansinventionisimportantbecauseitisveryaccurateandeasytouse.”,并根据对本段的整体理解可推知,本段主要说明了这项发明很重要的另一个原因,故选A。5.D承接上文“Therefore,itcanbeeffectivelyalmostanywhere.”可知,由于经济实用,这项发明几乎可以在任何地方使用,由此可知,这个简单且实惠的产品将会挽救全世界数以百万计患者的生命,故选D。.【文章大意】
