D.Worried.【解析】选B。推理判断题。根据黄磊对新系统识别率的陈述及最后一段中的Huangsaysheseestheinterestlikelyexpandingiftheviruscontinuestospreadandtheuseoffacemasksincreases.(黄说,他认为,如果病毒继续传播,口罩的使用增加,人们的兴趣可能会扩大)可推知,黄磊对这项新技术持乐观态度。8.Whereisthetextmostlikelyfrom?A.Atravelbrochure. B.Ahealthmagazine.C.Amedicalpaper. D.Asciencereport.【解析】选D。推理判断题。根据第一段中的AChinesecompanysaysithascreatedanewfacialrecognitionsystemthatcanidentifypeopleeveniftheyarewearingmasks.(一家中国公司表示,他们开发了一种新的面部识别系统,即使人们戴着口罩也能识别他们)及下文对该项新技术的介绍可知,这篇文章很可能来自一篇科学报告。Ⅱ.完形填空LastJuly4th,threepoliceofficerswentintoasupermarkettogetsomethingcoldtodrink.Onceinside,thecopswere1byastoresecurityguardwhoaskedfor2withasuspectedthief.Thewomaninquestiondidn’thavethelookofan3criminal.Shewasobviouslyscared,andhercheekswerewetwith4.
