Most people now get a lot of their news on electronic devices, instead of traditional media, such as newspapers, television or radio. An increasing number of people also report turning to social media for information.Now, there is a new technology that could greatly change the way we get the news: computercreated news readers. China has launched what it called the worlds first artificial intelligence, or AI news presenters.The news readers, supported by machine learning technology, are based on two real life Chinese newsmen. One is able to present news broadcast in English; the other, in Mandarin Chinese. A report said machine learning was used to examine video images and sounds of the two newsmen. Similar technology has been used to create video products known as “deepfake videos”. A deepfake video is a video that looks real, but is electronically changed. Such videos can make people appear to say things they never said.Its said that the AI presenters will be a great improvement to the news team because they “can work 24 hours a day” on its website and on social media. One of the presenters even promised to “work tirelessly” to keep people informed. Some machine learning experts said the system showed off Chinas latest progress in voice recognition, text to speech technology and data analysis.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 lowcost labor machines.Anyway, for its great potential, some businesses have experimented with similar technology for possible use in news operations.【解题导语】本文主要介绍了人工智能新闻主播的相关内容。1People now get information mainly from _Aelectronic devicesBtraditional mediaCsocial mediaDAI news presentersA解析：细节理解题。根据第一段第二句中的“Most people now get a lot of their news on electronic devices”可知，人们现在主要从电子设备上获得信息。2The author mentioned “deepfake” in Paragraph 3 because _Ait was also artificialBit was also developed by ChinaCit also used machine learning technologyDit also gained popularity and recognitionC解析：推理判断题。根据第三段第三、四句“A report said machine learning was used.known as deepfake videos”可推知，作者提到deepfake是因为它也用了机器学习技术。3What can we know about AI news presenters?AAI news presenters can only “speak” one language.BNot all the people are in favor of AI news presenters.CAI news presenters will soon replace human news readers.DAI news presenters can reflect the improvement in robot making.B解析：细节理解题。根据第五段的内容，尤其是“Others wondered about the effects robots might have on employment and workers.”可知，并不是所有人都支持人工智能新闻主播。4What will probably be discussed in the following paragraph?AFurther research on the technology.BOther advantages of the technology.CPrinciples the technology is based on.DExamples the technology is applied to.D解析：推理判断题。根据第六段中的“some businesses have experimented with similar technology for possible use in news operations”可知，接下来的一段很可能讨论这种技术所应用的例子。B(2020重庆质量抽测)Would a faster reading speed mean that we could learn more? Some people claim that its possible. In July last year, the sixtime speed reading champion Anne Jones sat down to read Harper Lees Go Set a Watchman. Just 25 minutes and 31 seconds later, she finished itwhich equals a reading rate of around 3，700 words per minute. Jones runs training courses teaching speed reading, recall and concentration techniques and there are numerous speed reading apps that have appeared on the market over the past few years. But do they actually work?First, we need to understand how we read. The human eye movement system is central to our reading ability. Read over that sentence again, and think about how your eyes scan across the words. They dont move smoothly over them. Instead, they make a series of short, sharp jumps, skipping over a few characters before briefly landing on a word. The movements are known as saccades(扫视) and the pauses are called fixations.Reading isnt just about seeing the wordsyou need to comprehend them to build up a picture about what the text means. People are able to get through a block of text faster, but at the cost of accuracy and understanding. In other words, if you use a speed reading app, then youll probably get the gist(主旨) of a piece of text, but youll struggle to recall details about what youve just read.So, does speed reading work? Well, yes and no. It really depends on what youre reading and why you need to read it. As yet, there isnt a trick that enables you to read a piece of text both quickly and accuratelytheres always going to be a tradeoff【解题导语】本文是一篇说明文，主要介绍了快速阅读有一定作用。虽然快速阅读能掌握文章的主旨，但是回忆细节还需要时间。5Whats the main idea of the passage?ASpeed reading is bad at times.BSpeed reading i
