Unit4 Lesson1 同步练习（2）
一、阅读理解（本大题共8小题，共16.0分）
A
China's lasting research and development efforts have helped the nation keep its pioneering role in developing 5G mobile communication technology, related standards and the licensing stage.
Chinese telecom companies are trying to keep their leading role in the global race for 5G commercialization (商业化). They are speeding up R&D of the fifth-generation mobile communication technology. The 5G technology is said to be at least 10 times faster than 4G services which means it will enable superfast downloads of "heavy" files like movies, self-driving cars and virtual (虚拟的) reality games. It will do large-scale experiments of using 5G in 17 cities. Yang Jie, chairman of China Telecom, said, "We aim to begin commercial 5G services in 2020."
China Mobile Communications Corp is planning to use 5G with AI and cloud technology for a latest network, which is planned to be used in the year 2020. The company has played an important role in the finish of the first stage of global 5G standards. The company will push forward the cloud deployment (云部署) of the superfast technology and build an intelligent network.
Similarly, China Unicom said it will start 5G testing this year, commercialize 5G in 2019 and finally carry out large-scale commercialization in 2020.
China is expected to have 576 million 5G users by 2025, according to a report published by EY earlier this month. With the global united standard set to be finished in the next year or so, China is likely to advance its plan for the commercial use of 5G connections to 2019, to possibly become one of the first 5G-ready markets in the world, EY forecast.
In the past, China was behind other countries in publishing 4G and 3G licenses. But in 5G, perhaps China will race ahead in R&D. China is struggling to take a leadership role in the global landscape. China is also hungry to join in the decision of 5G international standards, making it one of the major players.
The word "heavy" in the second paragraph refers to ______.
A. important B. long C. huge D. valuable
What can we infer about the passage
A. China attaches great importance to the commercial application of 5G.
B. The large-scale experiments of using 5G will be done in 17 cities by China Mobile.
C. China lay behind other countries in using 4G and 3G in the past.
D. China will decide 5G international standards in the future.
According to EY forecast, the year when China plans the commercial use of 5G connections is likely to be _____.
A. 2018 B. 2019 C. 2020 D. 2025
The best title of this passage is _____.
A. The 5G technology in China
B. Three communication companies in China
C. The commercial use of 5G in China
D. Chinese carriers wrest (争夺) 5G lead
B
A new study has shown how computers and robots powered by artificial intelligence can read human eye movements to "read" human personalities.
The eyes, they say, are the windows to the soul. And if that is true, computers and robots powered by sophisticated artificial intelligence algorithms (算法) may soon have the ability to peer into your soul. That is the result of a new study on the connection between eye movements and personality, conducted by neuroscience researchers based at the University of South Australia and published in the scientific journal Frontiers in Neuroscience.
"Eye movements during an everyday task predict aspects of our personality," wrote the researchers, led by University of South Australia neuroscientist Tobias Loetscher, whose team follows 42 study subjects around the university campus recording their eye movements, then determines their personality traits (特点) with "well-established questionnaires" for determining personality type, according to a summary of the study published by the site Science Daily.
The researchers fed the data into their Al algorithms and found that computers running the algorithms were able to record human eye movements and immediately determine a person's major personality traits, such as "neuroticism, extraversion (外向)，agreeableness, conscientiousness, as well as perceptual curiosity", the scientists wrote.
"The new findings could improve the way human beings interact with their computers and other high-tech devices, even robots, allowing for more natural and realistic social interactions with machines," Loetscher said.
"People are always looking for improved, personalized services. Today's robots and computers are not socially aware so they cannot adapt to non-verbal information," Loetscher said in a statement quoted by Indian Express. This research provides opportunities to develop robots and computers so that they can become more natural, and better at interpreting human social signals."
The study revealed previously undiscovered relations between specific personality characteristics and specific eye movement tendencies, according to a summary in Britain's Daily Mail newspaper.
What do the underlined words "peer into" in Paragraph 2 probably mean
A. Understand. B. Stare at.
C. Search for. D. Concern about.
How did the researchers conduct the research
A. It was carried out in a lab.
B. 42 subjects' eye movements were recorded.
C. The students' daily movements were tracked.
D. Its subjects' personalities were determined by computer.
According to Tobias Loetscher, what can we know
A. Robots and computers are socially conscious.
B. People care less about improved, personalized services.
C. Today's robots and computers can accustom to non-verbal information.
D. The discovery will improve the interaction between human beings and machines.
What can be a suitable title for the text
A. Human Personality Traits
B. What Human Eye Movements Are
C. Tell Personalities by Eye Movements
D. How Humans and Machines Interact

2.此处考查被动语态。网购现在被人们所喜爱和欢迎。主语online shopping是单数形式。故填is welcomed。
