[单项选择]Wide World of Robots
Engineers who build and program robots have fascinating jobs. These researchers tinker (修补) with machines in the lab and write computer software to control these devices. "They’re the best toys out there," says Howie Choset at Carnegie Mellon University in Pittsburgh. Choset is a robotics, a person who designs, builds or programs robots.
When Choset was a kid, he was interested in anything that moved — cars, trains, animals. He put motors on Tinker toy cars to make them move. Later, in high school, he built mobile robots similar to small cars.
Hoping to continue working on robots, he studied computer science in college. But when he got to graduate school at the California Institute of Technology in Pasadena, Choset’s labmates were working on something even cooler than remotely controlled cars: robotic snakes. Some robots can move only forward, backward, left and right. But snakes can twist (扭曲) in many directions and travel over a lot of different types of terra

[填空题]No one knows who the father of the World Wide Web is, except Berners-lee himself.
[单项选择]
Originally, the World-Wide Web was designed as information medium for (71) research teams. A deliberately simple implementation model was chosen to make it as simple as possible for authors to (72) documents to the web, and to (73) these in the sense of updating content. This implementation model is centered around the notion of resources, usually file-base D. For the (74) intended use of the web, resources presented a useful abstraction, as they related to relatively self-contained chunks of information such as research publications and (75) pages. Such chunks of information typically could be set up and maintained independently of other resources, so that resources were the appropriate abstraction for composition and modification.
