No matter how much better than us computers are in fields such as calculating and analyzing,we humans still have a few skills that are exclusive to us-keeping secrets,for example.But don't feel too relieved just yet,because computers may be catching up faster than we thought.
The Google Brain team has been working on computing systems called"neural networks"-systems that were designed based on how neurons work in the human brain.
This time,they gave a mission to three of the neural networks,which they named Alice,Bob and Eve.
Each of the networks had its own job-Alice sent messages to Bob,Eve tried to"eavesdrop"(偷听)and find out the messages,and Alice and Bob had to figure out a way to hide the messages from Eve.
All the help that Alice and Bob got from the researchers before the mission began was made up of a set of numbers,which Eve didn't have access to.
At first,Alice was not very good at sending secret messages.But slowly it worked on a way to encrypt (加密)them-putting information into a special code so that others could not understand it even if they got the information 一 using the numbers given by researchers.And
after practice,Bob also came to be able to decrypt (解密)Alice's messages.
Without the numbers or keys,Eve failed to understand Alice's"speech"most of the time.This test is considered a big step in the development of computers,learning skills.
"Computing with neural networks on this scale has only become possible in the last few years,so we really are at the beginning of what's possible,"Joe Sturonas of US encryption company PKWARE told New Scientist magazine.
Unfortunately,the test happened only one week after UK physicist Stephen Hawking,while speaking at Cambridge University,warned how artificial intelligence could develop a will of its own.This could be"either the best or the worst thing ever to happen to humanity",he said.
But just as Sturonas pointed out,no matter what the possibilities of computers are in tlie future,they are just starting out.We still have plenty of time to work out a solution before they get anywhere near becoming a threat to humanity.
46.The underlined word"exclusive"in Paragraph 1probably means"___".
A.common
B.limited
C.convenient
D.important
47.The Google Brain team did the test to find out___.
A.how neural networks encrypt and decrypt
B.how neural networks communicate with each other
C.if neural networks could develop a will of their own
D.if neural networks could keep their communication private
48.Which of the following statements is TRUE about the test?___
A.Alice was responsible for sending messages because she was good at encryption.
B.Alice and Bob learned to encrypt and decode with the help of researchers.
C.Eve often found it hard to make sense of the messages Alice sent to Bob.
D.The three neural networks worked together on the numbers given by researchers.
49.What can we conclude from the article?___
A.Artificial intelligence is not great at blind decryption,at least for now.
B.Artificial intelligence is now able to decode encrypted text without any guidance.
C.The more advanced artificial intelligence is,the more we can benefit from it.
D.Stephen Hawking is strongly against the development of artificial intelligence.
50.What is the author's attitude toward the development of artificial intelligence?___
A.Optimistic.B.Worried.C.Doubtful.D.Neutral.
