  1.D2.B3.C4.C5.A

  分析:

  短文大意:这篇短文主要讲述了一种新型的机器人,一种新技术将使得机器人在损坏后也能继续工作.1.Untilnoweventhemostadvanced(先进的)robotwasalmostcertaintobreakdownwhenitwasdamaged.描述,可知是因为当机器人改变时,电脑就不工作了。故选D。2.Forthefirsttimescientistshavemadearobotthatcantakeabeating(挨打)andkeepongoing.描述,可知新技术将使得机器人在收到损坏后也能继续工作。故选B。3.Itmaysomedayhelpscientistscreatebetterartificial(假的)armsandlegs描述,可知这个人称代词指代的是前文提到的假肢,故选C。4.andtwosensors(传感器)thatreadhowthemachineisworking.描述,可知传感器是用来感知机器人的状况的。故选C。5.
