问题     Robot. It is a word that seems very modern. A word that creates a strong mental picture. A picture of something that looks and acts like a human. Robots are not【S1】______, of course. They are machines.
    The word robot , and robots themselves, are less than 100 years old. But humans have been【S2】______of real and imaginary copies of themselves for thousands of years. Early people made little human statues out of clay. And they cut【S3】______and stone to look like humans.
    What is the future of robots? The goal of scientists is to【S4】______a true human-like robot. Some experts have described this robot of the future as one that can act【S5】______with the physical world through its own senses and actions. Humans have the【S6】______to see, hear, speak and solve problems. Engineers have built robots that have one or two of these abilities. But it takes a number of big expensive computers to make the robots work.
    The【S7】______problem in creating a human — like robot is copying human intelligence. The way the human mind works is almost【S8】______to copy. A simple computer can do mathematical problems far beyond the ability of even the smartest human mind. But the human mind is【S9】______than a thousand supercomputers at speaking, hearing and problem solving. Several American and Japanese companies are working to develop the senses of sight and touch for robots. The development of these senses will make robots【S10】______more useful.
    However, the most important human ability — the most difficult to copy — is problem solving. An intelligent robot must be able to change the way it acts when it faces an unexpected situation. Humans do it all the time. Computers must do it for robots. This means computers must have a huge base of information about many things. They must be able to find quickly the needed information in their systems. And they must make choices about how to act. So far, this is beyond the ability of computers.
A) worse B) create C) ability D) possible
E) imagine F) dreaming G) better H) wood
I) human J) impossible K) much L) independently
M) biggest N) copy O) robot
【S7】
选项
答案M
解析 当我们无法根据上下文的意思来选择答案时，可以从语法角度思考。从“The一problem”可以知道，要填充的是一个形容词。纵观所有剩下的选项，只有worse，better和biggest是形容词。一般使用比较级时有明显的两个比较范围，并且有比较标记词“than”，但是此句没有任何的比较级标记词，由此可以断定答案为"biggest”。本句意为：制造类似人类的机器人最大的问题就是模仿人的智慧。
