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.”

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”。
