A branch of AI known as deep learning, which uses neural(神經(jīng)的) networks to scan through large volumes of data looking for patterns, has proven so useful that skilled practitioners can mand high sixfigure salaries to build software for Amazon, Apple, Facebook and Google. The standard route into these jobs has been a PhD in puter science from one of America39。s top universities. Earning one takes years and requires a personality suited to academia, which is rare among more normal folk. That is changing. Last month , a nonprofit education organization based in San Francisco, kicked off the third year of its course in deep learning. Since its foundation it has attracted more than 100, 000 students around the globe from India to Nigeria. The course and others like it, e with a simple idea: there is no need to spend years obtaining a PhD in order to practise deep learning. Creating software that learns can be taught as a craft, not as a high intellectual pursuit to be undertaken only in an ivory tower. Fast. ai39。s course can be pleted in just seven weeks. To make it accessible to anyone who wants to learn how to build AI software is the aim of Jeremy Howard, who founded with Rachel Thomas, a mathematician. He says school mathematics is sufficient. No. Greek. Letters, Mr. Howard intones, pounding the table with his fist for punctuation. Some experts worry that this will serve only to create a flood of unreliable AI systems which will be useless at best and dangerous at worst. In the earliest days of the Internet, only a select few nerds, namely puter holies with specific skills, could build applications. Not many people used them. Then the invention of the World Wide Web led to an explosion of web pages, both good and bad. But it was only by opening up to all that the Internet gave birth to online shopping, instant global munications and search. If Mr. Howard and others have their way, making the development of AI software easier will bring forth a new crop of fruit of a different kind.（1）What can we learn about deep learning?

Letters”沒有，希臘，字母“是想說fast, ai的深度學習課程很簡單。故選A。 （4）考查推理判斷。根據(jù)最后一段中的”If Mr Howard and others have their way, making the development of AI software easier will bring forth a new crop of fruit of a different kind. “如果霍華德和其他人如愿以償，那么讓AI軟件開發(fā)變得更容易將會催生出一批新的不同的果實。由此推斷簡化軟件開發(fā)可能會導致意料之外的結(jié)果。故選D。 【點評】本題考點涉及細節(jié)理解，句義猜測和推理判斷三個題型的考查，是一篇科研類閱讀，要求考生準確掌握細節(jié)信息，同時根據(jù)上下文的邏輯關(guān)系，進行分析，推理，從而選出正確答案。5．閱讀理解 Some people sit outside for hours without getting bitten by mosquitoes, but it always seems like you39。re being eaten alive within minutes of stepping outdoors. If this is you, you39。re not alone. According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoe
