【答案解析】[解析] 22-25 W: And now here's our guest, David Newman, to tell us about the robot Twendy-One, which is one of today's major exhibits. Good morning, David. I'm especially curious about your robot's name. Why do you call it Twendy-One? M: Well, (22) the name represents a 21 st century version of Wendy, an earlier version. W: That's really a meaningful name. Are there any differences between Twendy-One and Wendy? M: (23) Twendy-One is designed to help care for the aging population; therefore he has a light touch and a soft grip. But don't be fooled—he has enough strength to support a man to sit or stand. At the same time, he can pick up and serve a loaf of bread without crushing it. W: Twendy-One is no doubt a capable assistant. (24) How do you manage to balance strength and flexibility? M: (24) Yes, this is our key breakthrough—but it has taken almost seven years and cost millions of pounds to assemble the 241 pressure-sensors in each silicon-wrapped "hand" and the ability to speak. In order for the robot to safely co-exist with humans, researchers have equipped it with a large number of touch and force feedback sensors to detect and react to collisions in order to prevent injuries. W: Injuries? Will the robot hurt human beings? (25) With his square head, big round eyes and long arms, he puts us in mind of E.T. from the science fiction movies. M: Aha, no. I mean injuries to the robot. You know our robot is very expensive. Our researchers are demonstrating the robot helping an elderly person get out of bed and preparing breakfast for him. Shall we go and have a look? W: That would be wonderful. 22.Why is the robot called Twendy-One?
