____5____

sendsanotificationtothecaregiver’ssmartphone”中的“發(fā)送消息”可推測，這種傳感器在患者下床時進行監(jiān)測。故選A。12．考查副詞詞義辨析。句意：該傳感器被設(shè)計為在患者下床時進行監(jiān)測，特別是在他們本應(yīng)休息的時候，并立即向護理者的智能發(fā)送通知。A.incredibly難以置信地；B.immediately立即；C.basically基本上；D.gradually逐漸。根據(jù)下文“Thesmallsensorisfastsendinganalarmassoonastheresidentbeginsto____12____.”可知，傳感器進行檢測后，會立即向護理者的智能發(fā)送通知。故選B。13．考查形容詞詞義辨析。句意：這款能夠改變生活的設(shè)備的靈感對Kenneth來說有著深刻的個人意義。A.conditional有條件的；B.rational理性的；C.personal個人的；D.professional專業(yè)的。根據(jù)下文“Idon’tthinkIwilleverforgetmy
