It's always nice to have a little help around the house.But what if you could employ the assistance of one of the greatest minds of the 20th century?
That's the idea behind a new robot modelled after Albert Einstein.Called Professor Einstein and standing at just over a foot tall,this personal assistant can tell you the weather and keep track of your schedule like any other robots.With built-in Wi-Fi,Einstein robot has access to brain ceasing games,and can answer math problems and science questions.With natural language speech processing,you can actually interact with Professor Einstein.And because the robot is connected to the Internet,it is constantly updated with new information.
To help get the perfect replica(复制品) of Einstein,a tech company Hanson Robotics turned to the Hebrew University of Jerusalem,the home of the Albert Einstein archives(档案).“We worked very closely with them to bring the product to marker,” the company's Dr Jeanne Lim said.
Einstein robot was introduced to the public at the Consumer Electronics Show in Las Vegas and was quickly hailed by those who saw it.“He became one of the breakout stars of the convention,” wrote Melia Robinson.“Crowds flooded into the company to have a look at the little guy.”
“Technology is often now very cold and socially isolating(孤立的),” explained David Hanson,the cofounder of the company behind the new robot,“By bringing an lively character into our physical world,we're humanising(使更人道) the technology instead of dehumanising the humans.”
As for Hanson Robotics,the company has been building human-size robots for over a decade.But this marks the company's first commercially available product.“Professor Einstein is just the start,” said Hanson.“We're witnessing the arrival of conversational robots that can walk in our world.It's a golden age of invention.”
4.What can Einstein robot do?
A.Teach you to learn any new language.
B.Have a regular conversation with you.
C.Design a number of science questions.
D.Keep track of other robots constantly.
答案B
解析细节理解题。根据第二段中的“Withnaturallanguagespeechprocessing,youcanactuallyinteractwithProfessorEinstein.AndbecausetherobotisconnectedtotheInternet,itisconstantlyupdatedwithnewinformation.”可知,因为有了自然语言语音处理并且和互联网相连接,你可以和爱因斯坦机器人互动聊天。故选B项。
5.Which of the following best explains “hailed” underlined in paragraph 4?
A.Broken. B.Improved.
C.Ignored. D.Praised.
答案D
解析词义猜测题。根据文章第四段可知,在这款机器人出现在展览会上被介绍给公众后,MeliaRobinson 认为它“becameoneofthebreakoutstarsoftheconvention”。同时在最后一句还提到“Crowdsfloodedintothecompanytohavealookatthelittleguy.”。由这两处可知,大家对这个机器人的认可度很高,它受到了公众的欢迎。故选D项。
6.What can be inferred from David Hanson's words?
A.He expects humans to be less isolated from robots.
B.He dreams of humanising humans through invention.
C.He worries about a golden age for conversational robots.
D.He stays hopeful about the future of robot invention.
答案D
解析推理判断题。根据最后一段中的“‘ProfessorEinsteinisjustthestart,'saidHanson.‘We'rewitnessingthearrivalofconversationalrobotsthatcanwalkinourworld.It'sagoldenageofinvention.'”可知,我们处于发明的黄金时代,见证了对话机器人的到来。他对机器人的发明充满了希望。故选D项。
7.What can be a suitable title for the text?
A.A New Robot Makes Humans Much Happier
B.The Golden Age of Invention Is Approaching
C.Albert Einstein Changes into an Assistant
D.Albert Einstein Helps to Humanise Robots
答案C
解析标题归纳题。根据文章第一段中的“It'salwaysnicetohavealittlehelparoundthehouse.Butwhatifyoucouldemploytheassistanceofoneofthegreatestmindsofthe20thcentury?”可知,此处的“greatestmind”指的就是下文第二段提及的以爱因斯坦为原型的新型机器人(Einsteinrobot)。文章第二段提到Einsteinrobot 这个私人助理可以帮忙做很多事情,如:tellyoutheweatherandkeeptrackofyourschedule以及youcanactuallyinteractwithProfessorEinstein。因此根据上下文可知,本篇文章讲述的就是将Einsteinrobot变成一个助理。故选C项。
C
Earthquake rescue robots have experienced their final tests in Beijing.Their designers say with these robots,rescuers will be able to save lives during an earthquake.
This robot looking like a helicopter,is called the detector-bot.It's about 4 metres long,and it took about 4 years to develop the model.Its main functions are to collect information from the air,and send goods of up to 30 kilos,to people trapped by an earthquake.
This robot has a high definition 360 degree panoramic(全景) camera.It can work day and night and will also be able to send the latest pictures from the quake area.
Dr Qi Juntong,Chinese Academy of Science,said,“The most important feature of this robot is that it doesn't need a distant control.We just set the destination information on it,and then it takes off,and lands by itself.It flies as high as 3,000 metres,and as fast as 100 kilometres per hour.”
This robot has a different function — it can change as the environment changes.Its main job is to search for any signs of life in places where human rescuers are unable to go.
As well as a detector that finds victims and detects poisonous gas,a camera is placed in the 40-centimetre long robot,which can work in the dark.
Another use for the rescuers is the supply part,with its 10-metre long pipe.People who are trapped in the ruins,will be able to get supplies including oxygen and liquids.
Experts have said that the robots will enter production,and serve as part of the national earthquake rescue team as soon as next year.
8.According to the passage,this robot　　　. 
A.is carried by the helicopter
B.weighs about 30 kilos
C.is a machine with a length of 10 metres

Technology is forever changing the way we get our news.Many people now get a lot of their news on electronic devices,instead of traditional media,such as newspapers,television or radio.Now,there is a new way we get the news:computer-created news readers.
Recently,a China's company launched the world's first AI news presenters with the Chinese search engine.The news readers created by machine learning technology are based on two real-life newsmen.One is able to present newscasts in English;the other,in Mandarin Chinese.
One report said machine learning was used to examine video images and sounds of the two newsmen,which look and sound like real people.
Some machine learning experts said the system showed off China's latest progress in voice recognition,text-to-speech technology and data analysis.But several experts suggested that the term AI does not correctly describe abilities of the robotic news readers.
On social media,many Chinese noted that the AI presenters did not seem real.People blamed them for not being more lifelike.Others wondered about the effects robots might have on employment and workers.Some people argued that only low-level jobs requiring heavy labour will be easily replaced by robots.Others praised the technology as a way for companies to make money from low-cost labour machines.
Some businesses have experimented with similar technology for possible use in news operations.One of Britain's company recently released a video that used machine learning to make it look like one of its news readers speaking different languages.The London-based company that developed the system says its goal is to “remove the language barrier” for many different kinds of video across the Internet.
12.What does the author intend to do in paragraph 1?
A.Introduce the topic of the text.
B.Summarise the different opinions.
C.Add some data about the AI presenters.
D.Compare different ways of getting news.
答案A
解析推理判断题。第一段首句说明科技永远在改变我们获取新闻的方式,最后一句“Now,thereisanewwaywegetthenews:computer-creatednewsreaders.”引出了本文的话题:computer-creatednewsreaders。故选A项。
13.What is the machine learning technology used to do?
A.To keep AI presenters from making any mistakes.
B.To make AI presenters speak more fluently.
C.To ensure images and sounds are like real persons.
D.To bring newscasts up to date every hour.
答案C
解析细节理解题。根据第三段中的“...machinelearningwasusedtoexaminevideoimagesandsoundsofthetwonewsmen,whichlookandsoundlikerealpeople.”可知,这一技术用来检查视频图像和声音,以使图像和声音看起来或听起来就像真人一样。故选C项。
14.What are some people worried about when AI presenters were launched?
A.Robots will eventually replace human all over.
B.Robots may threaten some people's employment.
C.Robots may endanger most people's health.
D.Robots will rule over the world in the end.
答案B
解析细节理解题。根据倒数第二段中的“Otherswonderedabouttheeffectsrobotsmighthaveonemploymentandworkers.”可知,有些人对机器人会给就业带来的影响感到忧虑。故选B项。

阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。
Do you know what a big dream is?Does a big dream show one's future?Or,is a big dream something that provides only entertainment?Children dream big dreams,but there are three barriers to realising dreams.　16　. 
The self
Immediately following the birth of a big dream,a negative self-talk takes over and gives all the reasons why it cannot happen.This voice inside of people is the ego(自我).It's there for protecting and should be listened to.Sometimes it is right,but more often it is wrong.　17　.That's why only a handful of people make their dream come true. 
Family and friends
Family and friends are a lot the ego.　18　,so they will often list all the reasons why the big dreams won't come true.Sometimes,family and friends destroy dreams of those they love most,out of their own fear of those left behind. 
　19　 
If one gets past the first two barriers,one has to face the world.It is the last and the most terrible barrier.In the past,big dreamers were locked up and sometimes even killed when they were shown to the world.Fortunately,in most of the world today,big dreamers just get laughed at.
　20　.When children feel confident and then try their best,they will be ready to accept any failure.The truth is that every great dreamer whose dreams have never seen the light of success knows failure well.They simply fail until they succeed. 
A.The world
B.The future
C.Most people are influenced by it
D.They want to protect those they love
E.And their big dream is to be a rock star or a famous artist
F.They often kill them before they ever have a chance to grow
G.The way to realise a big dream is with confidence and action
答案16.F　17.C　18.D　19.A　20.G

FaceshapeletsAIspotraredisorders
People with genetic syndromes (综合征) sometimes have revealing facial features,but using them to make a quick and cheap diagnosis can be 　21　 given there are hundreds of possible conditions they may have.A new neural (神经系统的) network that analyses photographs of faces can help doctors 　22　 the possibilities. 
Yaron Gurovich at biotechnology firm FDNA in Boston and his team built a neural network to look at the overall impression of faces and 　23　 a list of the 10 genetic syndromes a person is most likely to have. 
They 　24　 the neural network,called DeepGestalt,on 17,000 images correctly labelled to match more than 200 genetic syndromes.The team then asked AI to 　25　 potential genetic disorders from a further 502 photos of people with such conditions.It included the correct answer among its list of 10 responses 91 per cent of the time. 
Gurovich and his team also 　26　 the neural network's ability to distinguish between the different genetic mutations(突变,变异) that can lead to the same syndrome.They used photographs of people with Noonan syndrome,which can result from mutations in any one of five genes.DeepGestalt correctly identified the genetic source of the physical appearance 64 per cent of the time.It's clearly not 　27　,but it's still much better than humans are at trying to do this. 
As the system makes its assessments,the facial regions that are most helpful in the determination are 　28　 and made available for doctors to view.This helps them to understand the relationships between genetic make-up and physical appearance. 
The fact that the diagnosis is based on a simple photograph raises questions about 　29　.If faces can reveal details about genetics,then employers and insurance providers could,in principle,　30　 use such techniques to 　31　 against people who have a high probability of having certain disorders.　32　,Gurovich says the tool will only be 　33　 for use by clinicians. 
This technique could bring significant 　34　 for those who have genetic syndromes.The real value here is that for some of these ultra-rare diseases,the process of diagnosis can be many,many years.This kind of technology can help narrow down the search space and then be confirmed through checking genetic markers.For some diseases,it will cut down the time to diagnosis dramatically.For others,it could perhaps add means of finding other people with the disease and,　35　,help find new treatments or cures.

When I was a teenager,my father and I were standing in line to buy tickets for the circus.Finally there was only one family between the ticket office and us.
This family made a deep impression on me.There were eight children,all probably under the age of twelve.You could tell they didn't have a lot of money.Their clothes were not expensive,but they were clean.The children were well-behaved.They were excitedly talking about the clowns,elephants and other acts they would see that night with their brothers or sisters in a low voice.One could sense they had never been to the circus before.It promised to be a highlight of their young lives.
The father and mother were at the head of the pack,standing proud as they could be.The ticket lady asked the father how many tickets he wanted.He proudly responded, “Please let me buy eight children's tickets and two adults' tickets,so I can take my family to the circus.”
The ticket lady gave the price.The man's wife let go of his hand,lowered her head and her lips began to shake.The father leaned a little closer and asked,“How much did you say?” The ticket lady told him the price again.The man obviously didn't have enough money.
How was he supposed to turn and tell his eight children that he didn't have enough money to take them to the circus?Actually we were not wealthy in any sense,so I understand how the kids would feel.I felt sorry for them.

Seeingwhatwasgoingon,mydadputhishandinhispocket,pulledouta$20billanddroppeditontheground.Then he picked it up and tapped the man on the shoulder and said,“Excuse me,sir,this fell out of your pocket.”The man turned around and saw the money.He knew what was going on.He looked straight into my dad's eyes,hold my dad's hand in both of his and took the $20 bill.With tears in his eyes,he replied,“Thank you,thank you,sir.This really means a lot to me and my family.”
ThatdaymyfatherandIwenttoourcaranddrovehomewithoutanytickets.We didn't go to the circus that night,when I asked Dad why he did so,he said,“My child,it was a desperate and embarrassing situation for a father.Surely he wasn't begging for a handout,but he reminded me of my father,when I was young.” He paused for a while,as if wandering in his memory.“We should appreciate what we have obtained from life and seize every opportunity to help others.We didn't go to the circus tonight,but we still got a lot.”
