问题     The 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 7 kg, 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.
Which of the following is the most suitable title of this passage?
选项 A、New Entertainment Robots Produced in Japan.
B、QRIO—the Robot Dancers.
C、Robots—Man’s Best Friends.
D、An Extraordinary Performance in Sony’s Lab.
答案A
解析 主旨大意题。标题需要既全面又突出地概括文章的主题。本文先是描述“舞蹈演员”，然后揭晓这是些“机器人”(第2段第1句)，接着对Sony公司的一些机器人产品进行详细介绍。选项A比较全面地概括了文章内容。选项B、D只是涉及细节，不能全面地概括本文的内容。而C又过于笼统，不具有针对性。
