考研英语重在基础，建议广大考生在了解考研英语大纲的前提下，首先积累英语词汇量，并通过做阅读理解、翻译、写作等练习在词义方面加以提升，然后再考虑学习掌握答题技巧。当然，我们知道英语知识的复习是一个长期积累的过程。让我们跟随何凯文老师的每日一句。所谓：不积跬步，无以至千里;不积小流，无以成江海。坚持就是胜利!

And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can perform some kinds of brain and bone surgery with submillimeter accuracy — far greater precision than highly skilledphysicians can achieve with their hands alone.But if robots are to reach the next stage of labor saving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselves — goals that pose a real challenge. “While we know how to tell a robot to handle a specific error,” says Dave Lavery, manager of a robotics program at NASA, “we can’t yet give a robot enough ‘common sense’ to reliably interact with a dynamic world.”

48. According to the text, what is beyond man’s ability now is to design a robot that can ________.

[A] fulfill delicate tasks like performing brain surgery

[B] interact with human beings verbally

[C] have a little common sense

[D] respond independently to a changing world

And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can perform some kinds of brain and bone surgery with submillimeter accuracy — far greater precision than highly skilledphysicians can achieve with their hands alone.

But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselves — goals that pose a real challenge. “While we know how to tell a robot to handle a specific error,” says Dave Lavery, manager of a robotics program at NASA, “we can’t yet give a robot enough ‘common sense’ to reliably interact with a dynamic world.”

由于电子和微观机械仪器的不断缩小，现在已有一些机器人系统能够进行精确到毫米的脑部和骨髓手术，其精确性远远超过熟练的医生用他们的双手所能达到的水平。

但是如果机器人要进入节省劳力的下一个阶段，他们必须能够在更少的人工监控下运行，并且至少能够独立地做一些决定。这些目标给我们提出了一个真正的挑战。“虽然我们知道如何让机器人去纠正一个特定的错误，”NASA的一个机器人项目经理戴维•拉维里说，“我们仍然不能赋予机器人以足够的‘常识’，使它们能够与动态的世界进行可靠的交流。”

48. According to the text, what is beyond man’s ability now is to design a robot that can ________.

[A] fulfill delicate tasks like performing brain surgery

[B] interact with human beings verbally

[C] have a little common sense

[D] respond independently to a changing world

题型识别：细节题

题干定位：题干中出现了beyond含有否定的含义，题干的实质含义就是：现在人类所能设计出来的机器人还不能做什么?

根据这点可以确定是在But之后寻找答案，因为but前是在讲机器人能做什么。

思路解析：典型的细节题解题思路，定位读取后替换。

选项分析：[A] fulfill delicate tasks like performing brain surgery

在but前明确的表明了现在人类能够用手就能完成非常精确的手术，所以为错误答案。

[B] interact with human beings verbally

文中没有谈到和人类之间的言语互动

[C] have a little common sense

否定对象被扩大。文中提及的是：不能有足够的常识而不是没有一点常识。

[D] respond independently to a changing world

文中段落最后一句谈及：can’t reliably interact with a dynamic world. ( 不能可靠地和动态的世界互动)

选项中的independently就是对于reliably的替换，dynamic就是对于changing的同意替换。

所以D选项就是正确选项。
