14.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"(偷聽(tīng))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.

D.if neural networks could keep their communication private
48.Which of the following statements is TRUE about the test?C
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

2.Can dogs and cats live in perfect harmony in the same home?People who are thinking about adopting a dog as a friend for their cats are worried that they will fight.A recent research has found a new recipe of success.According to the study,if the cat is adopted before the dog,and if they are introduced when still young (less than 6 months for cats,a year for dogs),it is highly probable that the two pets will get along swimmingly.Two-thirds of the homes interviewed reported a positive relationship between their cat and dog.
    However,it wasn't all sweetness and light.There was a reported coldness between the cat and dog in 25% of the homes,while aggression and fighting were observed in 10% of the homes.One reason for this is probably that some of their body signals were just opposite.For example,when a cat turns its head away it signals aggression,while a dog doing the same signals submission.
    In homes with cats and dogs living peacefully,researchers observed a surprising behaviour.They are learning how to talk each other's language.It is a surprise that cats can learn how to talk'dog',and dogs can learn how to talk'Cat'.
    What's interesting is that both cats and dogs have appeared to develop their intelligence.They can learn to read each other's body signals,suggesting that the two may have more in common than we previously suspected.Once familiar with each other's presence and body language,cats and dogs can play together,greet each other nose to nose,and enjoy sleeping together in the sofa.They can easily share the same water bowl and in some cases groom(梳理)each other.
    The significance of this research on cats and dogs may go beyond pets--to people who don't get along,including neighbors,colleagues at work,and even world superpowers.If cats and dogs can learn to get along,surely people have a good chance.

47.Some cats and dogs may fight whenC.

The Man at the Market
When the supermarket clerk summed up my groceries,It was 12overwhatIhadonme.Ibegantoremoveitemsfromthebags,whenanothershopperhandedmea20 bill."Please don't put yourself out,"I told him.
"Let me tell you a story,"he said."My mother is in hospital with cancer.I visit her every day and bring her flowers.I went this morning,and she got mad at me for spending my money on more flowers.She demanded that I do something else with that money.So,here,please accept this.It is my mother's flowers."
A Family's Food Angel
Since my mother lost her job,our family troubled new worries:no income,the same bills,and no way to afford groceries.It was around this time that she started finding boxes of food outside our door every morning.This went on for months,until she was able to land a job.We never did find out who it was and who left the groceries for us,but they truly saved our lives.
Seven Miles For Me
Leaving a store,I returned to my car only to find that I'd locked my keys and cell phone inside.A teenager riding his bike saw me kick a tire and say a few choice words."What's wrong?"he asked.
I explained my situation."But even if I could call my wife,"I said,"she can't bring me her car key,since this is our only car."He handed me his cell phone."Call your wife and tell her I'm coming to get her key."
"That's seven miles round trip."
"Don't worry about it."
An hour later,he returned with the key.I offered him some money,but he refused."Let's just say I needed the exercise,"he said.Then,like a cowboy in the movies,he rode off into the sunset.
Breaking Bread
Last December,before work,I stopped at a deli (熟食店) and ordered an everything bagel with cream cheese.It was toasty warm,and I couldn't wait to dig in.But as I left the store,I noticed an older indigent gentleman sitting at the bus stop.Knowing it would probably be his only warm meal of the day,I gave him the bagel.
But all was not lost for me.Another customer from the deli offered me half of her bagel.I was so delighted because I realized that in one way or another,we are all looked after.
