More and more, the operations of our businesses, governments, and financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information for his own purposes can reap big reward. Even worse, a number of people who have done this and been caught at it have managed to get away without punishment.It's easy for computer crimes to go undetected if no one checks up on what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers.

     Of course, we have no statistics on crimes that go undetected. But it's disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures. The computer criminals who have been caught may have been the victims of uncommonly bad luck.

      Unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations and perhaps other benefits. All too often, their demands have been met.

     Why? Because company executives are afraid of the bad publicity that would result if the public found out that their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled (诈骗) the most confidential (保密)records right under the noses of the company's executives, accountants, and security staff. And so another computer criminal departs with just the  needs to continue his crimes elsewhere.

A) A strict law against computer crimes must be enforced
B) Companies usually hesitate to uncover computer crimes to protect their reputation
C) Companies will guard against computer crimes to protect their reputation
D) Companies need to impose restrictions on confidential information

4. What may happen to computer criminals once they are caught?
A) With a bad reputation they can hardly find another job.

   The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with humanlike ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (软件) or by altering the architecture but that too will happen.
    I think it certain that in decades, not centuries, machines of silicon (
) will arise first to rival and then exceed their human ancestors. Once they exceed us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe.
    As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands or millions of people, will be within our power. 

16. In what way can we make a machine intelligent?
A) By making it work in such environments as deserts, oceans or space.
B) By working hard for 10 or 20 years.
C) By either properly programming it or changing its structure.
D )By reproducing it.
17. What does the writer think about machines with human-like ability?
A) He believes they will be useful to human beings.
B) He believes that they will control us in the future.
C) He is not quite sure in what way they may influence us.
D) He doesn't consider the construction of such machines possible.

18. The word carbon( Line 4, para. 2) stands for" _______"
A) intelligent robots B) a chemical element
C) an organic substance D) human beings

19. A robot can be used to expand our frontiers when _______.
A) its intelligence and cost are beyond question
B) it is able to bear the rough environment
C) it is made as complex as the human brain
D) its architecture is different from that of the present ones

20. It can be inferred from the passage that _______.
A) after the installation of a great number of cells and connections, robots will be capable of self reproduction.
B) with the rapid development of technology, people have come to realize the possibility of making a machine with human-like ability.
C) once we make a machine as complex as the human brain, it will possess intelligence
D) robots will have control of the vast, man-made world in space.
