问题     Over the past week, the "world’s first" artificial intelligence (AI) news anchor has gone viral online, a robot version of a presenter at China’s state Xinhua News Agency.
    Lauded for "his" ability to broadcast 24 hours a day, the presenter said he would "work tirelessly to keep you informed. " The anchor was developed by Xinhua and Chinese search engine Sogou. com and launched at the World Internet Conference last week.
    But is this actually a true example of AI? Will Knight, a senior editor for AI at MIT Technology Review, is somewhat skeptical.
    "The use of the term AI is a little bit tricky in this context, because the anchor itself is not intelligent, it doesn’t have any intelligence…But they are using some quite clever kind of machine learning which is a sub-field of AI to capture the likeness of a real anchor and the voice of that anchor," Knight told CNBC by phone.
    When Knight first saw the anchor, he thought it was an impressive piece of mimicry. "The underlying technology for learning how to reproduce faces and voices is quite a sort of fundamental idea, and a quite powerful one potential. "
    If the anchor wrote its own script, that might be a different story. "If it were to get a bunch of reports, take some phone calls and then reproduce it, that would be incredible, but that’s way beyond what machines can do," he added.
    As with any new technology, terms can enter people’s vernacular before they are fully understood. "We should also always be really careful think about the use of the term AI, and in this context you don’t want to suggest that this anchor is actually exhibiting any intelligence, because it’s not, it’s just like a kind of very sophisticated digital puppet," Knight said.
    AI may have created the Xinhua anchor and its voice, but the anchor itself cannot think, Ali Shaf-ti, a research associate in robotics and AI at Imperial College London, told CNBC by phone. "What actually creates those images and the movement of the lips and the voice of this anchor is using algorithms that are related to artificial intelligence. But to call this an AI anchor is slightly overselling it. "
    Defining AI isn’t straightforward, Shafti said. "The term itself is usually defined as a non-human device or algorithm being able to do behaviors and actions that are possible only for a person of human intelligence, or maybe not even possible for humans, so above human intelligence," he said.
    Knight said this is an area that is currently prone to mistakes. "Doing something like writing a report using language is one of the most difficult things you could have a computer do. Language is so powerful and flexible so it’s easy for machines to fall into making lots of errors which you see with chat bots and the like," he told CNBC.
Which of the following words can best replace the word "straightforward" in the sentence "Defining AI isn’t straightforward" in Paragraph 9?
选项 A、candid
B、easy
C、going forward
D、clear
答案B
解析 词义理解题。straightforward出现在第九段第一句。由第七、第八段可知，正是因为人们没有真正理解人工智能这一概念，才出现人们将“播报员”误解成人工智能这一现象；再结合第九段第二句对人工智能的定义可知，对人工智能的定义需要小心、谨慎，否则就会产生类似的误解，即Defining AI isn’t straightforward表达定义人工智能并不容易，easy最符合文意，故B项为答案。candid意为“坦率的，坦诚的”；going forward意为“前进，向前”；clear意为“清楚的”。straightforward意为“简单的”。
