Passage OneThe dancers stand motionless at their position and the room grows silent. But as the music starts, they began to move, bending, turning and waving their fans gracefully as they perform a traditional Japanese dance. Yoshihiro Kuroki watches in silence, occasionally making notes. But as the dance ends, he beams with happiness. The performance has been flawless.There have been many performances of traditional Japanese dances over the centuries, but this one is unique, because it is performed not by human dancers but by robots. And the performance takes place not in a dance studio but in a laboratory of Sony Corp's Entertainment Robot Co. in Shinagawa, Japan, where Kuroki is general manager. He is the mastermind behind a series of even more capable humanoid entertainment robots, starting with the Sony Dream Robot, or SDR, in 1997, up to the current QRIO in 2003.These delightful machines are only 58 cm tall, about the size of a newborn infant, weigh about 7kg, and move with 38 degrees of freedom, each with its own servomotor (辅助马达).QRIO's predecessor, the SDR4X, announced in 2002, can walk, dance, sing, speak, recognize faces, and understand continuous speech. Each robot has two charge-coupled-device cameras to detect color and position and can locate a colored ball, move toward it, and kick it into a goal. It also has contact sensors in several joints to avoid pinching real human fingers. Seeing the robot perform, it is difficult to remember that there is no sentience (知觉) behind those glass eyes.1Which of the following is the most suitable title of this passage?A.New Entertainment Robots Produced in Japan.B.QRIO the Robot Dancers.C.Robots Man's Best Friend.D.An Extraordinary Performance in Sony's Lab.2Yoshihiro Kuroki ______.E.is excited when the robots are performing a traditional Japanese danceF.keeps silent because he is a little unsatisfied with the new productG.witnesses the creation of a series of entertainment robotsH.is an executive manager of Sony Corp.3Which aspect of the robots is NOT mentioned in the passage?I.The vividness of their motion.J.Their pleasant appearance.K.Their smart designing principles.L.Their communicative ability.4The Sony Dream Robot was ______.M.the first human-like entertainment robot developed by the Sony CorpN.as capable as the QRIO of speaking, dancing, singing and walkingO.largest among all the entertainment robots developed by the Sony CorpP.the first entertainment robot sold at the market by the Sony Corp5The robots can locate colored balls by means of ______.Q.a charge-coupled deviceR.two camerasS.two contact sensorsT.a digital detector
