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, China's Xinhua launched (推出) the world's first AI news presenters with the Chinese search engine Sogou. 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 Xinhua's 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 labor will be easily replaced by robots. Others praised the technology as a way for companies to make money from low-cost labor machines.
Some businesses have experimented with similar technology for possible use in news operations. Britain's BBC 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.
1.What does the author intend to do in Paragraph 1?
A.Introduce the topic of the text.
B.Summarize the different opinions.
C.Add some data about the AI presenters.
D.Compare different ways of getting news
2.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.
3.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.
4.From the last paragraph we know that______.
A.BBC has removed the language barrier in newscasts
B.BBC's news readers can speak different languages
C.BBC shows interest in Xinhua's AI news presenters
D.BBC has done similar experiments as Xinhua does

Though great progress has been made in science these years, there are still many people lived in poor conditions. They make their lives by collecting and selling used thing. Their children cannot go to school because they have not enough money to send their children to there. Why you think so many people still suffer from poverty now? The answer lies on the population explosion. A president of a developing country once said; “It is us who are to blame for the poverty because we used to ‘produce’ child without limit.” Although this few words sound simple enough, they have clear pointed out one of the causes of the population explosion.

There have been many great inventions that changed the way we live. The first great invention was one that is still very important today—the wheel. This made it easier to carry heavy things and to travel long distances. For hundreds of years after that there were few inventions that had as much effect as the wheel. Then in the early 1800’s the world started to change. There was little unknown land left in the world. People did not have to explore much anymore. They began to work instead to make life better. In the second half of the 19th century many great inventions were made. Among them were the camera, the electric light and the radio. These all became a big part of our life today.
The first part of the 20th century saw more great inventions. The helicopter in 1909. Movies with sound in 1926. The computer in 1928. And jet planes in 1930. This was also a time when a new material was first made. Nylon came out in 1935. It changed the kind of clothes people wear. The middle part of the 20th century brought new ways to help people get over disease. They worked very well. They made people healthier and let them live longer lives. By the 1960’s most people could expect to live to be at least 60. By this time most people had a very good life.
Of course new inventions continued to be made. But man now had a desire to explore again. The world was known to man but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then the United States took a step. Since then other countries, including China and Japan, have made their steps into space. In 1969 man took his biggest step away from the earth. Americans first walked on the moon. This is certainly just a beginning, though.
New inventions will someday allow us to do things we have never yet dreamed of.
1.Why did the world start to change in the early 1800’s?
A.Because there were few inventions that had as much effect as the wheel for hundreds of years.
B.Because people began to work to make life better instead of exploring unknown world.
C.Because there was little unknown land left in the world.
D.Because people did not have to explore much anymore.
2.In Paragraph 2, the word “They” in the sentence “They worked very well” refers to ________.
A.helicopters, computers, jet planes, nylon B.new materials
C.new ways to help people get over disease D.people
3.Why did man have a desire to explore again?
A.Going into space is a dream for man to realize.
B.Man wanted to move to other stars.
C.Other countries wanted to follow Russia.
D.Other countries wanted to catch up with America.

Electronic books have changed the way many people read for pleasure. Now online textbooks are changing the way some students learn and some teachers teach.
More than one hundred seventy-five thousand students attend the public schools in Fairfax County, Virginia, outside Washington. Last year, the school system used digital books in fifteen schools. This school year, middle schools and high schools changed from printed to electronic textbooks in their social studies classes.
Luke Rosa is a history teacher at Falls Church High School. His students work on laptop computers at school. He explains the idea to them this way. “I mean, it’s just like a regular textbook, except it’s got it all online.”
Peter Noonan, an assistant superintendent (助理监督) of schools, said, “The world’s changing. And the online textbooks can change right along with the events that are happening.” Digital books also cost less than printed textbooks, he said.
A student named Melanie Reuter said, “I don’t have to carry a textbook around, so that’s nice.”
But another student said, “I don’t like it because the Internet sometimes doesn’t work.”
Students also need access to the Internet when they are not at school. About ten percent of students in Fairfax Country do not have a computer or online access at home. Public libraries in the country have free Internet. There are also after-school computer labs as well as computer clubhouse supported by the country. Middle school student Slieman Hakim is happy about that. He said, “My family only has one computer; my sister and I both do our homework on it. So I come here to do my homework. It’s good.”
Other school systems in the area are also considering online textbooks.

The Internet has changed the world we live in dramatically, so that in some ways it is unrecognizable from the place we lived in twenty years ago. Communications have been revolutionized. Not only have cell phones found their way into most people’s pockets or purses, but they are also used for next messaging and as cameras. Long distance phone calls have been replaced by e-mail and video conferencing. Communications, person to person or company to company, have turned into a fast-paced exchange with instant response. In fact, it has become more convenient and efficient.
The other kind of communication the Internet provides is information. School children and medical researchers alike will tell you that they could not work without the Internet and its ability to connect them to any number of websites and databases of information. Many people do their banking on-line. Others plan a trip and book a flight for themselves. People do their own stock trading through the Net. Sports fans follow scores and statistics on websites. Political junkies(政治狂) gather campaign statements and debate topics, even between elections. And almost everyone who owns a computer and has Internet access has bought at least one item on-line. No wonder some young people can not imagine what life was like before the Internet.

Advances in artificial intelligence and the use of big data are changing the way many large companies recruit (招募) entry level and junior management positions. These days, graduates’ CVs may well have to impress an algorithm (算法) rather than an (human resources) manager.
While algorithms supposedly treat each application equally, experts are divided about whether so-called robo-recruitment promises an end to human prejudice in the selection process —or whether it may in fact add to it.
“AI systems are not all equal,” says Loren Larsen, chief technology officer for HireVue, which has developed an automated video interview analysis system. “I think you have to look at the science team behind the work,” says Mr Larsen.
The problem, experts say, is that to find the best candidates an algorithm has first to be told what “good” looks like in any given organization. Even if it is not given criteria that seem discriminatory, a powerful machine-learning system will quickly be able to copy the characteristics of existing workers. If an organization has favoured white male graduates from well-known universities, the algorithm will learn to select more of the same.
The growing dependence on automation to judge suitability for everything from a loan to a job worries Yuriy Brun, an associate professor specializing in software engineering. “It takes a lot of the time for a company to put out software but it doesn’t know if it is discriminatory” he says. Prof Brun explains that, considering the use of big data, algorithms will unavoidably learn to discriminate.
Many of those working with robo-recruiters are more optimistic. Kate Glazebrook, the leader and co-founder of Applied, a hiring platform, says her task is to encourage hiring manager to move away from such indicators of quality as schools or universities and move to more evidence-based methods. When candidates complete tests online, Applied hides their names and shows the tests the candidates have completed, question by question, to human assessors. Every stage of the process has been designed to remove prejudice.
With the same aim, Unilever decided in 2016 to switch to a more automated process for its graduate-level entry programme. Unilever worked with HireVue, Amberjack, which provides and advises on automated recruitment processes, and Pymetrics, another high volume recruitment company, which developed a game-based test in which candidates are scored on their ability to take risks and learn from mistakes, as well as on emotional intelligence. Unilever says the process has increased the ethnic diversity of its listed candidates and has been more successful at selecting candidates who will eventually be hired.
“The things that we can do right now are impressive, but not as impressive as we’re going to be able to do next year or the year after,” says Mr Larsen.
Still, robo-recruiters must be regularly tested in case prejudice has occurred without anyone realizing it, says Frida Polli, the leader and co-founder of Pymetrics. “The majority of algorithmic tools are most likely causing prejudice to continue existing. The good ones should be examined.”
1.What’s the purpose of adopting automated recruitment processes according to the passage?
A. For the sake of fairness.
B. For the purpose of cutting down costs.
C. To relieve the pressure of staff.
D. To favor graduates from well-known universities.
2.The automated process Unilever adopted in 2016 for its graduate-level entry programme ________.
A. was found to have prejudice
B. was copied by many other companies
C. scored the candidates on their ethnic backgrounds
D. turned out to be less or not racially discriminatory
3.According to Mr Larsen, robo-recruitment ________.
A. is good enough for wide use now
B. is not suitable for practical use now
C. will do better and better in the near future
D. will completely replace HR staff within two years
4.Frida Polli stresses in the last paragraph that algorithmic tools ________.
A. need routine checks
B. will unavoidably have prejudice
C. are mostly good and effective
D. must be combined with human staff
