1 . Professor Stephen Hawking recently came out with a serious warning for people. While at the Starmus Festival, a festival in Trondheim, Norway, celebrating science and the arts, Hawking warned people that the human race is in serious danger.
Hawking criticized President Donald Trump for denying climate change. Then the physicist warned the audience, “I am not denying the importance of fighting climate change and global warming, unlike Donald Trump, who may just have taken the most serious, and wrong, decision on climate change this world has seen.”
Hawking proposed that the leading countries should send astronauts to the Moon before 2020 to restart a movement of more exploration in space. BBC reported that Hawking suggested that we “build a lunar base in 30 years’ time and send people to Mars by 2025.”
According to BBC, Professor Hawking said, “Spreading out into space will completely change the future of humanity.” He continued, “I hope it would unite competitive nations in a single goal, to face the common challenge for us all.” The physicist shared more ideas to motivate the younger generation to continue exploring space. Hawking stated, “a new and ambitious space program would excite (young people), and stimulate interest in other areas, such as astrophysics and cosmology.”
Hawking also revealed his vision for other forms of energy that could move us to a new planet. He warned the audience, “The Earth is under threat from so many areas that it is difficult for me to be positive.” He continued, “Our natural resources are being drained, at an alarming rate. We have given our planet the disastrous gifts of climate change, rising temperatures, reduction of the polar ice caps, deforestation, and decimation (大量毁灭) of animal species. We can be ignorant, unthinking lot (人).”
The professor warned the audience that doing nothing would lead nowhere. He said, “If we succeed, we will send a probe (航天探测器) to Alpha Centauri within the lifetime of some of you alive today. It is clear we are entering a new space age. We are standing at the threshold (起点) of a new era. Human colonization and moving to other planets is no longer science fiction, and it can be science fact.” Hawking advised the audience to move to other worlds because we are running out of space.

2 . 
News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world’s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday, three months after a male robot joined the profession.
Unlike previous news robots though, Xin does not read news like a cold machine; she reads it almost like a human being. The muscles on her face stretch and relax-and her reactions change-as she continues reading. That’s why many news anchors were worried: Will AI replace us in the near future?
To find the answer, we have to analyse the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the Al news anchor reads, the micro -electric motors behind her face move to make her expressions seem more human.
Yet we need a thorough knowledge of deep leaning technology to make a robot imitate a person’s voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them Into the machine and match them with the text or the Al to lean and read. The process for imitating facial movements is similar. The developer has to analyse the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to lean, and imitate the movements of facial muscles via programs
Both the technologies used to make Xin’s performance impressive are mature. The real difficulty lies in the third -the technology to match the pronunciations with facial movements so that Xin expressions vary according to the content of the news report. In fact, Xins expressions don' t always change according to the content. As a result, her expressions look anything but human. Actually. AI is still no match for human qualities.

3 . In 2015, a man named Nigel Richards memorized 386, 000 words in the entire French Scrabble Dictionary in just nine weeks. However, he does not speak French. Richards’ impressive feat is a useful example to show how artificial intelligence works — real AI. Both of Richard and AI take in massive amounts of data to achieve goals with unlimited memory and superman accuracy in a certain field.
The potential applications for AI are extremely exciting. Because AI can outperform humans at routine tasks — provided the task is in one field with a lot of data — it is technically capable of replacing hundreds of millions of white and blue collar jobs in the next 15 years or so.
But not every job will be replaced by AI. In fact, four types of jobs are not at risk at all. First, there are creative jobs. AI needs to be given a goal to optimize. It cannot invent, like scientists, novelists and artists can. Second, the complex, strategic jobs — executives, diplomats, economists — go well beyond the AI limitation of single-field and Big Data. Then there are the as-yet-unknown jobs that will be created by AI.
Are you worried that these three types of jobs won’t employ as many people as AI will replace? Not to worry, as the fourth type is much larger: jobs where emotions are needed, such as teachers, nannies and doctors. These jobs require compassion, trust and sympathy — which AI does not have. And even if AI tried to fake it, nobody would want a robot telling them they have cancer, or a robot to babysit their children.
So there will still be jobs in the age of AI. The key then must be retraining the workforce so people can do them. This must be the responsibility not just of the government, which can provide funds, but also of corporations and those who benefit most.
1. What is the main purpose of paragraph 1?| A．To introduce the topic. |
| B．To mention Nigel’s feat. |
| C．To stress the importance of good memory. |
| D．To suggest humans go beyond AI in memory. |
| A．Be superior to | B．Be equal to |
| C．Be similar to | D．Be related to |
| A．The writer. | B．The shop assistant. |
| C．The babysitter. | D．The psychologist. |
| A．Limit the application of AI to a certain degree. |
| B．Get more support from the government. |
| C．Apply for the donation from companies. |
| D．Upgrade themselves all the time. |
4 . What will higher education look like in 2050? That was the question addressed Tuesday night by Michael Crow, president of Arizona State University.
“We’re at the end of the fourth wave of change in higher education,” Crow began, arguing that research universities followed the initial establishment of higher education, public colleges, and land-grant schools in the timeline of America.
In less than a half-century, he said, global market competition will be at its fastest rates of change ever, with several multi-trillion-dollar economies worldwide. According to a recent projection, the nation’s population could reach 435 million, with a large percentage of those residents economically disadvantaged. In addition, climate change will be “meaningfully uncontrollable” in many parts of the world.
The everyday trends seen today, such as declining performance of students at all levels, particularly in math and science, and declining wages and employment among the less educated, will only continue, Crow maintained, and are, to say the least, not contributing to fulfilling the dream of climbing the social ladder mobility, quality of life, sustainable environment, and longer life spans that most Americans share.
“How is it that we can have these great research universities and have negative-trending outcomes?” Crow said in a talk “I hold the universities accountable. … We are part of the problem.”
Among the “things that we do that make the things that we teach less learnable,” Crow said, are the strict separation of disciplines, academic rigidity, and conservatism, the desire of universities to imitate schools at the top of the social ranks, and the lack of the computer system ability that would allow a large number of students to be educated for a small amount of money.
Since 2002, when Crow started being in charge at Arizona State — which he calls the “new American university” — he has led more than three dozen initiatives that aim to make the school “inclusive, scalable, fast, adaptive, challenge-focused, and willing to take risks.”
Among those initiatives were a restructuring of the engineering and life sciences schools to create more linkages between disciplines; the launch of the School of Earth and Space Exploration and the School of Sustainability; the start of a Teachers College to address K-12 performance and increase the status of the Education Department at the university; and broadened access, increasing the freshman class size by 42 percent and the enrollment of students living below the poverty line by 500 percent.
Universities must start, Crow noted, “by becoming self-reflective architects, figuring out what we have and what we actually need instead of what legend tells us we have to be.” Research universities today have “run their course,” he added. “Now is the time for variety.”
During a discussion afterward, Crow clarified and expanded on some of his points. He discussed, for example, the school’s distance-learning program. “Nearly 40 percent of undergraduates are taking at least one course online,” he said, which helps the school to keep costs down while advancing interactive learning technologies.
He said that Arizona State is working to increase the transfer and completion rates of community-college students, of whom only about 15 percent, historically, complete their later degrees. “We’ve built a system that will allow them to track into universities,” particularly where “culturally complex barriers” beyond finances limit even the most gifted students.

5 . When people see machines that respond like humans, or computers that perform amazing feats of strategy, they sometimes joke about a future in which humanity will need to accept robot overlords. But buried in the joke is a seed of unease. Science fiction writing and popular movies have shown us about artificial intelligence (AI) that exceeds the expectations of its creators and escapes their control, eventually outcompeting and enslaving humans or targeting them for extinction(灭绝).
Even in the real word, not everyone is ready to welcome AI with open arms. In recent years, as computer scientists have pushed the boundaries of what AI can accomplish, leading figures in technology and science have warmed about the frightening dangers that artificial intelligence may pose to humanity, even suggesting that AI capabilities could destroy the human race.
But why are people so frightened about the idea of AI?
Elon Musk is one of the famous voices that have raised red flags about AI, In July 2017. Musk told attendees at a meeting of the National Governors Association, I have exposured to the very cutting-edge Al,and I think people should be really concerned about it.I keep sounding the alarm bell. But until people see robots going down the street killing people, they don't know how to react, because it seems so impossible."
Earlier, in 2014, Musk had labeled AI "our biggest existential threat," and in August 2017, he declared that humanity faced a greater risk from AI than the terrorists. Physicist Stephen Hawking, who died on March14, also expressed concerns about AI, telling the BBC in 2014 that "the development of full artificial intelligence could spell the end of the human race.

6 . In the movie Jurassic Park (1993) a billionaire creates a theme park filled with dinosaurs, brought back from extinction through cloning by a team of scientists.
Although the film is of course fictional, the methods used in it to bring animals back from the dead may soon become reality.
Scientists from Harvard University in the US are currently working on resurrecting the woolly mammoth, a mammal that became extinct around 4,000 years ago.
However, it wouldn't be an exact copy of the hairy beast. "Our aim is to produce a hybrid elephant-mammoth embryo,” Professor George Church, head of the team of scientists, told The Guardian.
“Actually, it would be more like an elephant with a number of mammoth traits. We're not there yet, but it could happen in a couple of years."
The team is hoping to make a “mammophant”- a mix between an elephant and a mammoth. It would be like a regular elephant but have features from the mammoth that would make it more adaptable to cold weather.
Small ears, a thick layer of body fat and, of course, long hair are what helped the mammoth live in freezing temperatures.
So why go through all the effort and expense to bring back an animal that died out thousands of years ago? The answer lies in climate change.
It's hoped that the creatures will stop frost in the world's tundra from melting and releasing huge amounts of harmful greenhouse gases into the atmosphere.
Mammoths used to keep the tundra from thawing by punching through snow and allowing cold air to come in," said Church. In the summer, they knocked down trees and helped the grass grow."Church and his team are attempting to mix mammoth DNA, recovered from frozen samples of the animal found in Siberia, with that of the Asian elephant, which is its closest relative.
There are critics who believe that the media has got carried away with the story though, after several websites ran headlines such as Woolly mammoths will be roaming Earth again within two years.
“So far, scientists have managed to incorporate traits of the mammoth into elephant DNA. In a few years, they hope to make an embryo, but that's a long way from creating a viable embryo, "Popular Science magazine wrote.
Some have even gone so far as to call the story “fake news". Paleoanthropologist(古人类学家)John Hawks wrote on blog platform Medium: Is this just another case of the media sensationalizing(大肆渲染) what is otherwise a good science story?"
Although we may not be seeing woolly mammoths at the zoo any time in the near future, it's still exciting to know that there is still the possibility of a real Jurassic Park someday, however tiny that possibility may be.

7 . Whether in the home or the workplace, social robots are going to become more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.
While household robots today do the normal housework, social robots will be much more like partners than tools. For example, these robots will be able to tell when someone is happy or sad. This allows them to respond more properly to the user.
The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn’t just give general answers to questions; it responds based on what it learns about each person in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.
Social robots are not just finding their way into the home. They have potential(潜在的) applications in everything from education to health care and are already finding their way into some of these areas.
Fellow Robots is one company bringing social robots to the market. The company’s “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product’s location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.
The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not aimed to replace workers, but to work together with other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.
