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．

分析 本文是一篇說(shuō)明文，說(shuō)明了狗和貓可以和平相處，它們相互學(xué)習(xí)、理解自己的語(yǔ)言，通過(guò)這篇文章，人們也應(yīng)該和平相處，積極打造和平世界．

解答 46．D 推理判斷題，由第一段最后一句Two-thirds of the homes interviewed reported a positive relationship between their cat and dog三分之二的家庭采訪報(bào)告了他們的貓和狗的關(guān)系，可以推斷出swimmingly意思是平滑，流暢與smoothly意義相近，故選D．
47．C 細(xì)節(jié)理解題，根據(jù)第二段第3行One reason for this is probably that some of their body signals were just opposite．說(shuō)明貓和狗不能好好相處的原因是他們的肢體信號(hào)所表達(dá)的意思是相反的，會(huì)引起對(duì)方的誤解，所以選C．
48．C 細(xì)節(jié)理解題，根據(jù)第四段3，4，5行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 on the sofa．說(shuō)明貓和狗在相處的過(guò)程中，智力都有了提高，能夠?qū)W會(huì)說(shuō)對(duì)方的語(yǔ)言．所以選C．
49．B 推理判斷題，根據(jù)第4段2，3行They can learn how to read each other's body signals，suggesting that the two may have more in common than we previously suspected．說(shuō)明貓和狗身上的差別要比我們預(yù)料的要少，共同點(diǎn)比預(yù)料的要多，故B項(xiàng)內(nèi)容正確．所以選B．
50．A 推理判斷題．根據(jù)文章最后一行If cats and dogs can learn to get along，surely people have a good chance．說(shuō)明如果貓和狗都能和平相處，那么我們?nèi)祟惛鼞?yīng)該和諧的生活在一起．故A正確．

點(diǎn)評(píng) 本文講述了貓和狗能夠在一起和諧相處的情況，文章中做了一個(gè)調(diào)查，研究了貓狗不能和平相處的原因，并提出了相關(guān)的建議，如何讓二者和諧相處，最后還推廣到人類生活．考查了較多的推理題，解此類題需要結(jié)合上下文提供的語(yǔ)境和信息進(jìn)行簡(jiǎn)單的概括和判斷．

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．

46．The underlined word"exclusive"in Paragraph 1probably means"B"．
A．common
B．limited 
C．convenient
D．important
47．The Google Brain team did the test to find outD．
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？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
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
A．Optimistic．B．Worried．C．Doubtful．D．Neutral．

6．Once Chinese students in American schools were largely limited to graduate students．Gradually that trend shifted，with more students coming from China to earn bachelor's degrees at American institutions．Now，the population is widening once again，with many Chinese students studying in the U，S．from ever-younger ages．
Bill Zhou，a resident of California，though born in Shenzhen，and his wife are currently housing just such a student：Hsu，also from Shenzhen，who is living with Zhou （a paid arrangement） while he attends a private，religious institution．．
Although Zhou is caring，he knows there are many people taking advantage of the trend who lack conscience．In a Lost Angeles Times article，Zhou described his reservations about the current system．"They don't know if the school is good．They don't know if the home stay is good．But everyone else is doing it，so they do it，too，"Zhou said，addressing the parents of so-called parachute（降落傘）children，who earn the nickname by"parachuting"into the U．S．by themselves，unaccompanied by family．
Based on statistics，Zhou has reason to be concerned．A recent article in Sixth Tone'，stated that the number of Chinese students enrolled at U．S．secondary schools increased from just 647 in 2006 to more than 46，000 in 2016．Those numbers are reflected in Chinese society and even popular culture，where a new television drama titled"A Love for Separation"was released several months ago．
"It is a common misunderstanding that studying in a private American high school is easier than in China，a mother told．"My son is under enormous pressure to compete with accomplished peers．He was very lonely during his first year of high school，and found it hard to assimilate into an unfamiliar environment．"
Chinese parents send their teenagers abroad for varieties of reasons．For some students，it is to escape the strict Chinese education system； for others，it is a second chance to recover from bad grades or a low score on China's college entrance exam．For still others，it is simply a lifelong dream．

24．What's Bill Zhou's attitude towards the trend of growing parachute children？C
A．Positive'．B．Indifferent      C．Concerned       D：Opposed
25．What does the underlined phrase"assimilate into"in Paragraph 5 mean？D
A．show respect to   B．get rid of     C．take advantage of    D．fit in with
26．Which is not the reason why increasing parents send their little children abroad？B
A．They just follow the crowd．
B．They just show off their large treasure．
C．They want their children to break away from Chinese education system．
D．They want to give their children with poor grades another chance to succeed．．
27．What's the author's purpose in writing the text？D
A．To help these parents to choose a reliable home stay．．
B．To remove these parents doubts about studying abroad．．
C．To encourage these parents to send their kids abroad as early as possible．
D．To remind these parents to be more sensible before sending their kids abroad..
