Passage ThreeQuestions 31 to 35 are based on the following passage:

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 human, of course. They are machines. The word robot, and robots themselves, are less than 100 years old. But humans have been dreaming of real and imaginary¹ copies of themselves for thousands of years. Early people made little human statues out of clay². And they cut wood and stone to look like humans.What is the future of robots The goal of scientists is to create a true humanlike robot. Some experts have described this robot of the future as one that can act independently with the physical world through its own senses and actions. Humans have the ability 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 biggest problem in creating a humanlike robot is copying human intelligence³. The way the human mind works⁴ is almost impossible to copy. A simple computer can mathematical⁵ problems far beyond the ability of even the smartest human mind. But the human mind is better than a thousand supercomputers at speaking, hearing and problem solving. Several American and Japanese  to develop the senses of sight and touch for robots. The development of these senses will make robots much 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 unexpected⁶ situation. Humans do it all the time. Computers must do it for robots. This means⁷ 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.

31.According⁸ to the passage, however intelligent a robot may be, it ____.
A) acts as an ordinary animalB) is nothing but a machine
C) is viewed as a modern mythD) is regarded as a human being

32.Which of the following conclusions is best supported by 
A) Robot does not last long.
B) The early men made toys themselves.
C) Man has always had a desire to make a copy of himself.
D) The materials for making a copy of man are limited.

33.From the third paragraph⁹, we can know that ____.
A) there has not been a true humanlike robot yet
B) computers in the robots are expensive
C) robots may do what they are told
D) robots have been designed to work independently

34.According to the passage, why has human intelligence not been copied in the making of a robot
A) Computers can only do mathematical problems better than human beings.
B) Technology is not advanced enough to copy how human minds work.
C) Scientists are satisfied¹⁰ to have the robot with senses of sight and touch.
D) Robots with human intelligence will be dangerous to human beings.

35.In order to enable¹¹ the intelligent robot to deal with an unexpected situation, the computers in it must do the following things except ____.
A) having a large amount of information
B) making choices about how to act
C) studying the situation carefully
D) finding the information quickly
