  • Artificial intelligence is set to benefit mankind in many ways. It will make everyday tasks easier and bring efficiency to various industries. It might just prove to be one of man's greatest inventions. And yet, like any other technology, AI will also bring risks and dangers. When people mention that AI could be dangerous, most people think of scenarios from movies or books where an AI program decides to eliminate(消灭)or conquer all humans.
        In February 2018, a group of AI experts got together to discuss the potential misuse of AI. Their main concern was that criminals could use AI for evil purposes. Someone can use AI to create websites that could be used to steal people's personal information. Another potential risk is faster hacking(非法入侵)-AI programs could be taught to find loopholes in software and break into secure computer systems. Some of the risks were as dramatic as the ones we see in books and movies. For example, the experts mentioned automated terrorism (自动化的恐怖主义) by using drones(无人驾驶飞机)or unmanned vehicles as weapons. Remote attacks using such could be made easier through the use of AI.
        And finally, there were some concerns about the fact that AI can mimic voices as well. Last year the US filmmaker Jordan Peele teamed up with BuzzFeed to make a movie using AI techniques to copy former US President Barack Obama's voice. They "had" him voice his opinions on the 2017 movie Black Panther and current US President Donald Trump. While in China, the tech giant Baidu, has also developed a program called Deep Voice that can "copy" anyone's voice by analyzing a 3.7-second audio sample.
        The famous British physicist Stephen Hawking even thought AI could be the worst event in the history of our civilization. "Once humans develop artificial intelligence, it will take off and redesign itself at an alarming rate. Humans couldn't compete and would be superseded," he told the BBC. However, Hawking suggested, "I believe we can create AI for the good of the world. We simply need to be aware of the dangers, identify them, employ the best possible practice and management, and prepare for its consequences well in advance."
        Actually, AI technology is making great progress in terms of the three-stage development of artificial intelligence. It is unlikely that fully developing AI would make it hard for mankind to survive. After all, without human intelligence, AI cannot even develop itself, let alone replace human civilization.

    (1)According to the text, which of the following is NOT the risk brought by AI?
     

    A.AI can be used to create websites to steal people's personal information.
    B.AI can help criminals to break into secure computer systems without permission.
    C.AI can be used by terrorists to carry out terrorist attacks.
    D.AI can be used to clone humans.
    (2)What does the underlined word "mimic" in Paragraph 3 mean?
     

    A.Imitate.
    B.Disturb.
    C.Record.
    D.Change.
    (3)What can we infer from Stephen Hawking's words?
     

    A.AI is the best invention in the history of our civilization.
    B.AI is not as intelligent and creative as humans.
    C.AI can identify the dangers in advance.
    D.AI will benefit the world if under careful management.
    (4)Which best describes the author's attitude towards the future of AI?
     

    A.Worried.
    B.Indifferent.
    C.Positive.

  • "More and more consumers across the country are using cashless payment methods. The rapid development of third-party mobile payment tools is helping to encourage cashless payments across the country," said Dong Ximiao, a researcher at Renmin University of China.
        Although there were 3.4 billion third-party payment accounts(账户)in total in China in 2016, China is not the first country to seek a cashless society. Developed countries like Sweden, Denmark and Singapore are also seeing that increase.
        However, the rapid development of cashless payments does not mean there are no challenges and criticisms. Alibaba's Hema store has come under the spotlight recently. The media said that consumers can't buy goods with cash there, which would be considered illegal.
        Alipay and WeChat Pay, the nation's two major third-party mobile payment tools, also launched campaigns this month to encourage more people to use cashless payment methods, which caused concern over whether cash will soon disappear.
        "Some offline sellers refuse to accept cash, which influences the natural circulation(流通)of cash," said Dong. He stressed that a cashless society would not mean that cash would completely disappear. "Also it's important to remember that nearly half of China's population live in the country, and they are unable to enjoy innovation(革新)brought by the Internet," said Dong. "And when it comes to China's senior citizens, most of them prefer to use cash in their daily lives," he added.
        "It's ridiculous(荒谬的)to question digital payment tools' contribution to financial development. In the long term,various payment methods will be used by consumers, and merchants should respect consumers' payment habits," Dong noted.

    (1)What does the underlined word "that" in Paragraph 2 probably refer to?
     

    A.The economic activity.
    B.A large amount of payment.
    C.Development of the economy.
    D.The cashless payment.
    (2)Why has Alibaba's Hema store become a focus?
     

    A.It fights against illegal activities.
    B.Customers are not permitted to use cash there.
    C.It provides comprehensive services.
    D.It starts campaigns to encourage mobile payment.
    (3)What is Dong Ximiao's attitude towards the payment in the future?
     

    A.The cashless payment should be limited in the countryside.
    B.The innovation from payment is ridiculous in fact.
    C.Various payment methods should be encouraged.
    D.The digital payment should replace cash completely.
    (4)What is the best title of the passage?
     

    A.Innovation on the Internet
    B.Cash or cashless?
    C.Payment online should replace cash
    D.Is the circulation of cash dying?

  • Learning online should make use of a number of Internet tools. For example, e-mail lets you exchange letters between continents very cheaply and almost immediately. Large groups of people can share their discussions by using electronic lists to send every letter to everyone on the list. Electronic magazines bring you up-to-date topics, such as news, arts, and sports. Search engines allow you to look for anything you want on the Internet, including the holdings of major libraries. In a chat room you can have a real-time written talk. Audio and video bring the world to your computer-you can listen to the world's radio stations,and watch the evening news from another continent. And in an online conference you can even talk to your teacher and fellow students abroad.
        Do you have an e-mail box? How much time do you spend communicating with your friends over the Internet? The Internet, the newest child in technology, is like a modern communication highway. It's also a kind of super-shop where you can buy almost anything-you can get anything through the Internet, without leaving home at all.
