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.”

　　【答案速查】　1－4　BADC

　　【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 ofB．make use of

　　C．keep track of

　　D．catch sight of

　　【解析】　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 YouTube，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”。
