26、 The effect of artificial intelligence(AI)will be felt across various industries,and advertising is no different.From programmatic buying to e﹣commerce,AI is already changing how brands connect with consumers.The real future of AI in advertising will rely on people working together to create experiences which bring real value to consumers.
"Brands don't just exist because of what they say but because of what they do.They must create new customer interactions(互动),"says Ogilvy Consulting Senior Partner Pierre Robinet."These interactions have to be useful,sharable and personal,providing an essential service at the right moment and in the right place."
It is predicted that by 2020,85 per cent of customer interactions will be managed without the need for a human being.This presents a fantastic opportunity to rethink customer strategy(策略).How do we connect with an AI﹣empowered customer who speaks more than he writes,who uses his face and fingers to interact with his devices,who prizes a hassle﹣free experience?
"AI is going to influence the revenue(收益)structure of any company,"says Robinet."Sellers are always trying to be more exact in predicting which product you want to get from their platform.Amazon is already moving goods into their warehouses(仓库)based entirely on predictive demand,moving the model from'shopping then delivery'to'delivery then shopping.'"We are presently in an exciting period of experimentation,where brands and marketers are exploring the different possibilities and applications of AI.Decision﹣makers now must figure out how AI can influence business models and be a driver of growth.
In order to overcome fear and mistrust of issues like the mishandling of data,Robinet believes that each and every consumer should be equipped to understand these technologies so they can make a wise decision."On one side,we need more fairness and ethics(道德标准)in AI,as well as specific frameworks and rules to do so,"he says."While on the other,we need to give people the right tools,services and education,and motivate them to share their data."
【1】What is the author's attitude towards using AI in advertising?
A.Cautious.
B.Favourable.
C.Doubtful.
D.Worried.
【2】What does the underlined word"hassle﹣free"in Paragraph 3 most probably mean?
A.Real﹣life.
B.First﹣hand.
C.Convenient.
D.Professional.
【3】Why is Amazon mentioned in Paragraph 4?
A.To show AI can help entirely reshape business models.
B.To explain sellers always know customers better.
C.To prove consumers are likely to interact with machines.
D.To show AI can free people from tough jobs.
【4】What can we infer from the last paragraph?
A.People's fear of AI is increasing.
B.AI can help people make decisions.
C.More and more people are unwilling to share their data.
D.People must know AI well before they accept it.
27、 Entering a university is an important part of a person’s life. Today, many people go to a university to study and train for a future job in subjects like law, medicine or education. 【1】. An important one started in Egypt over one thousand years ago.
The world’s oldest surviving university, AL-Azhar, is in Cario, Egypt. It was first built as a mosque for religion (宗教寺院) in A.D.972. A few years later, learners and teachers began meeting in the mosque. They read and talked about the subject of religion and law. 【2】. Leaders in the city of Cario decided to create a school for higher learning and soon after that, and AL-Azhar University was founded.
【3】. For these teachers at AL-Azhar, they needed to think about what courses to teach and how to teach them. The earliest courses were in law and religion. In a course, students read and studied with the teachers, but there was also free discussion. Often, students and teachers had interesting discussions, and there was no ‘right’ answer. In the years that followed, the new university interested scholars from around the world. 【4】. At AL-Azhar, people studied the past, but it was also a place for sharing new ideas.
Over a thousand years later, AL-Azhar is still an important university in the world. 【5】. Today, many of the world’s most important universities such as Oxford and Harvard still follow the same traditions as they do at AL-Azhar.
A. However, the university is not a modern invention.
B. There are many reasons to study in Egypt.
C. They came here to teach and do research.
D. Around the year 988, a new decision was made.
E. Its library contains many of the world’s oldest and most valuable books.
F. The cost of university education is increasing year by year.
G. A university was a new idea at that time.
28、Many of us live with a roommate at some stage. Sometimes, there can be problems. Who hasn’t had an argument about whose turn it is to take out the rubbish or who should be the one to clear up after dinner? However, living with another person also comes with many benefits.
You know that there’s always someone else around, which can help you feel safer. There is always someone to talk to, so you never feel lonely. Besides these obvious benefits, there are some you may not notice. For example, we’re actually more likely to eat healthier food when living with others.
To examine the effect of living alone, Australian university researchers did much research and found that people living alone tended to eat less fresh food, which can have a significant negative effect on long-term health. However, those living with others generally benefited from a more varied diet compared to those living alone.
What could explain these findings? The researchers believe the social and cultural roles played by cooking, food preparation and eating may be important considerations. For example, those living with friends have someone else to go shopping with, and thus are likely to buy higher-quality fresh food regularly.
Cooking skills may be another factor. If people living alone find they do not have the knowledge required to prepare a particular dish or cook a certain food,they may fall back on ready-made, less healthy food. However, if they live with at least one other person, they may be able to ask for help.
In addition, people living alone can eat whatever they want at any time of the day or night. However, it’s helpful to have someone around who questions your decision to eat frozen pizza at 3 am. In other words, roommates can draw your attention to unhealthy routines.
So,if you now live alone and find yourself fighting a losing battle against poor eating habits, why not consider sharing a home with someone else? You could encourage one another on to greater health and well-being.
【1】The author uses the first paragraph to ______.
A.introduce the topic of the text
B.remind readers of their roommates
C.show the problems of living with others
D.recall the experience of sharing a room
【2】The second paragraph is mainly about _______.
A.The reasons for living with others
B.the benefits of having a roommate
C.the way of dealing with a roommate
D.the importance of communicating with others
【3】The underlined phrase”fall back on” in Paragraph 5 means________.
A.hunt for
B.cut down on
C.depend on
D.give up
【4】What is the main purpose of this text?
A.To explain why roommate have arguments.
B.To tell readers every coin has two sides.
C.To encourage people to have a roommate.
D.To persuade people to develop healthy eating habits.
29、We fill our water bottle with cool water from a stream and watch as puffy clouds slowly push shadows over the green hills. At the country' s first camping site, Glamping Georgia, in Ambrolauri, six white tents are set on a hill, overlooking a valley and slopes of dense pine forest. There’s a bathroom inside the air-conditioned tents, and a mini kitchen outside, a private deck with wicker rocking chairs. Linden, oak and apple trees surround the tents. The clean, fresh air is rich with birdsong and insects zip back and forth. The only other sound is the Krikhula River. It's the perfect place to disconnect. A layer of stars opens up overhead and Giorgi, the owner, drops by to give us a bottle of his homemade grape.
We spend the final days of our trip in central Georgia, at Borjomi, a summer retreat for the Romanovs, famous for its mineral waters and sulphur(硫磺)baths. Covering 210,000 acres, the Borjomi-Kharagauli National Park has one of the largest areas of old-growth forest in Europe, and many wildlife habitats. There are 12 marked tracks for hiking, riding and snowshoeing, as well as . tourist shelters and camping areas.
We hike the Nikoloz Romanov Trail from Likani to Lomis mountain where a river valley leads up through forest to alpine meadows(高山草甸) of tall grasses and wild flowers. We pass only a handful of other hikers. I know that the reward at 7,200ft will be the views. What I don't expect to find at the top are free -ranging horses with shiny brown coats, a tiny decorative church and carpets of wild flowers.
This is what we came for—undamaged nature and slow travel. It's a few hours’ hike back down, but all I want to do is lie down among the flowers, close my eyes and just breathe.
【1】What is the author' s impression of Glamping Georgia?
A.It is not easily accessible.
B.It is a densely populated area.

34、Directions:Fill in each blank with a proper word chosen from the box. Each word can only be used once. Note that there is one word more than you need.
A huge milestone has just been reached in the field of artificial intelligence: AlphaGo, a program developed by Google’s DeepMind unit, has defeated legendary Go player Lee Se-dol in the first of five historic matches being held in Seoul, South Korea. Lee 【1】 after about three and a half hours, with 28 minutes and 28 seconds remaining on his clock. The series is the first time a professional 9-dan Go player has taken on a computer, and Lee is 【2】 for a $1 million prize.
“I was very surprised,”said Lee after the match.“I didn’t expect to lose. But I didn’t think AlphaGo would play the game in such a perfect manner.”DeepMind founder Demis Hassabis expressed“huge 【3】 for Lee Se-dol and his amazing skills.”calling the game“hugely exciting”and“very tense.”Team lead David Silver said it was an“amazing game of Go that really pushed AlphaGo to its 【4】.”
Go is an ancient Chinese board game that has long been considered one of the great 【5】faced by AI. While computer programs ow best the world’s leading human players of games like checkers and chess, the high level of intuition and 【6】required by Go has made it tough for computers to crack. DeepMind’s AlphaGo program is the most 【7】effort yet, using a complex system of deep neural networks and machine learning; it beat European champion Fan Hui last year, but Lee Se-dol is another 【8】 rival entirely.
“I don’t regret accepting this challenge,”said Lee.“I am in shock, I admit that, but what’s done is done. I enjoyed this game and look forward to the next. I think I failed on the opening layout so if I do a better job on the opening aspect I think I will be able to increase my 【9】 of winning.”Lee was surprised both by how strong AlphaGo’s opening was, and by some 【10】moves.
35、Directions: Complete the following sentences by using the proper form of the words or expressions given in the frame. Each one can only be used once.
Why your Password May Not Be As Safe As It Seems? Does “qaz2ws” strike you as a nice safe password? What about “adgjmptw”? An analysis has found them to be among the passwords that are most 【1】 used, which of course means they are not secure at all.
When ten million passwords were leaked on to the internet,they appeared to 【2】that attempts by internet security experts to make us improve our password strength had been successful, even if, in the specific case of the leaked passwords, they are also completely pointless.
While many of the passwords were still single words, such as “password”,there was also a clear attempt by many to make them harder to【3】. The problem was that people seemed to do so in the same way.
“Users are becoming slightly more 【4】what makes a password strong,” explained WP Engine, an internet company that performed the analysis. “For instance, adding a number or two at the end of a text phrase. That makes it better, right?”
But 【5】no. They found that almost half a million passwords did this and in 20 percent of those all people did was put the number “1” at the end.
Perhaps this is why some companies are now trying to move gradually beyond passwords. Yahoo! is giving users the option to 【6】 their mobile phone with an account, having a single use passwords texted to it each time they want to log on.
Although the serviced is voluntary, Dylan Casey an executive at Yahoo!,said that it was “the first step to【7】passwords”. He said it was a(n)【8】that it was increasingly hard for people to remember all the passwords they had. “I don’t think we, as an industry, have done a good enough job of putting ourselves in the shoes of the people using our products,” he said.
It would certainly be a more sensible strategy than same people’s improving upon “password” by using “password” or,“tran5p053d numb3r5 f0r 133tr3r5”.
“We are, for the most part,predictably【9】when it comes to choosing passwords, despite a decade of warnings from password strength checkers during sign-ups” said WP Engine. “We love taking a(n) 【10】, and so do password crackers.

Yet, some people are【1】 They claim that surfing the Internet is a waste of time. They make the 【2】 that children spend too much time chatting and playing games instead of 【3】 on their school work. However, a recent survey conducted in the USA shows that 80 per cent of Internet users 【4】 it mostly to search for answers to questions. The second most common use of the Internet, for 79 per cent of Internet users, is to find out information about hobbies. These statistics prove that gathering information is the 【5】 use for the Internet.
37、Directions: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.
Driving an electric car 【1】 to the protection of environment, or so the marketing departments of their makers would have you believe. Yet a report which analyzes car emissions presents a rather different picture. A battery-powered car recharged with 【2】 generated by coal-fired power stations, it found, is likely to be more harmful. It could cause more than three times as many deaths from pollution as a 【3】 petrol-driven vehicle.
The study was carried out by the University of Minnesota. The researchers estimated how levels of fine particulate matter (细颗粒物) and ground-level ozone — two important 【4】 of air pollution — would change when a car is powered by different ways.
It was no surprise that electric cars whose batteries were recharged with power from wind, solar or hydro-electric sources came out to be virtually free from harmful 【5】. They were estimated to cause 231 deaths over the course of a year, compared with 878 for petrol cars. Electric cars recharged with power from natural gas-fired stations were also a lot less harmful than petrol-driven ones, with 439 deaths. But if those same electric cars were recharged 【6】 by coal, they would be responsible for over 3,000 deaths.
Biofuels also caused more health problems than petrol. But diesel, which often 【7】 concern about pollution, is slightly cleaner than petrol. This is because the study assumes for all cars that emission-control technologies will be more widely used, especially particulate filters which have a remarkable effect on cleaning diesel 【8】. Diesel cars are also more 【9】 of fuel than petrol-driven ones.
Overall, the study shows that electric cars are cleaner than those traditional vehicles only if the power used to charge then is also clean. That is hardly a surprise, but the 【10】 of the difference is. How green electric cars really are, then, will depend mainly on where they are driven. In France, which obtains more than half of its power from nuclear station, electric cars look like a good bet. In China and some other developing countries, where a large amount of electricity is produced from coal, they may not be so environment- friendly as they are marketed.
