问题 In the first paragraph the author introduces his topic by relating
Sony’s QRIO could carry out all the following work EXCEPT
选项 A、walking freely as it wishes.
B、understanding a few voice commands.
C、navigating automatically.
D、resuming walk when it falls over.
答案A
解析 细节题。文章第三段第二、三句提到"它(QRIO)行走，理解少数的声音命令，并能独立导航。如果它脸朝下跌倒，它会在停止的地方起来并重新开始"，由此可知索尼公司制造的机器人能够执行题目中其他三项所提到的任务；虽然文中提到它可以行走，但没有提到可以"随意"行走，所以答案选项为正确选项。
