　　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 isgeneral 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(輔助馬達).

　　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 andcan locate a colored ball, move toward it, and kick it into a goal. It also has contact sensors in severaljoints to avoid pinching real human fingers. Seeing the robot perform, it is difficult to remember that there is no sentience(知覺)behind those glass eyes.

　　1.[A] 主旨大意題。標題需要既全面又突出地概括文章的主題。本文先是描述“舞蹈演員”，然后揭曉這是些“機器人”(第2段第1句)，接著對Sony公司的一些機器人產品進行詳細介紹。選項A比較全面地概括了文章內容。選項B、D只是涉及細節，不能全面地概括本文的內容。而C又過于籠統，不具有針對性。

　　2.[C] 事實細節題。選項C符合第2段最后一句“He is the mastermind behind a series of... robots...”。仔細閱讀有關的細節信息會發現,第1段第3句可幫助否定選項A。第1段最后兩句可幫助否定選項B。另外，根據第2段倒數第2句可否定選項D。

　　3.[D] 事實細節題。全文分四段，分別討論機器人三方面的特點：第1段和第2段描述機器人舞蹈演員栩栩如生的表演，即選項A;第3段描寫它們的外表，即選項B;第4段介紹它們巧妙的設計，即選項C;只有選項D是沒有提到的，故為答案。

　　4.[A] 推理判斷題。該句中的分詞結構“starting with...”表明the Sony Dream Robot是第一個人形娛樂機器人，因此選項A正確。文章在最后一段的第1句提到兩種能說話、跳舞的機器人，但沒有提到SDR是否和它們一樣，由此可否定選項B。在第3段討論機器人大小的時候也沒有提到SDR體型最大，因此選項C不正確。選項D在文中沒有討論到。

　　5.[B] 事實細節題。該句中“two…cameras to...”的結構表明這兩個攝像頭可以用于定位，所以選項B正確。選項A在該句中也有提到，但它只是攝像機的工作機制，而不是用于定位的裝置。選項C在下一句提到，但與題干提到的定位功能無關。選項D在文中并未提及。
