"At present, the videos are fed electronically，" said research scientist Cornelia Fermuller. "Originally, we took our own videos, our cameras looking at us doing the cooking，" she explained. "And, as the robot advances, it reacts to good quality videos. And it will react to even lower quality home­made videos."

　　So far, the robot named Julia can make a simple salad by breaking each task into basic parts, such as grasping a spoon, bringing it to the bowl, stirring the salad and observing the results.

　　But why teach a robot how to understand a video when it can easily follow a fixed program? Aloimonos believes predetermined instructions lack flexibility. He thinks one of the problems is how to make the robot understand and use what it learns during a certain task, the so­called feedback (反馈意见); another is the introduction of language.

　　"I believe it will take quite some time before the robots are able to understand metaphorical (比喻性的) language，"he added."But，" he said, "we don't need that to create a new world where the robots will be working for us."

　　语篇解读：机器人按既定指令完成任务并不让人觉得新鲜，但能看着视频学做饭的机器人，你可能前所未闻。

　　1．The underlined phrase "capitalize on" probably can be replaced by ________.

　　A．take hold of　　　　　 　B．make use of

　　C．keep track of D．catch sight of

　　解析：选B　词义猜测题。由第二段的第一句"If you have posted a video of your favorite recipe on the popular website You Tube, chances are that it will be used by a robot."可知，机器人能利用网上大量的视频信息，结合第二段的最后一句可知，capitalize on应与"use"意思相近，因此选择B项。take hold of"握住"；make use of"利用"；keep track of"与......保持联系"；catch sight of"看到"。

　　2．Aloimonos probably agrees that at present the robot ________.

　　A．can not fully digest what it learns

　　B．can not make a simple salad

　　C．can follow home­made videos

　　D．can understand metaphorical language

解析：选A　推理判断题。根据最后一段Aloimonos的话可知，该机器人目前还不能理解比喻性的语言。根据倒数第二段的最后一句可推知，Aloimonos可能认为目前该机器人还不能完全消化它学的东西，应选择A项。
