【文章內(nèi)容簡介】 60。B.Reduced uptake of glucose.C.Having higher intake of glucose.D.Expected increase in brain function.（4）From which is the text probably taken? A.Science fiction.B.A chemistry book.C.A science research.D.A health brochure.【答案】 （1）A（2）C（3）B（4）C 【解析】【分析】本文是一篇說明文，介紹了如何預(yù)測你的記憶喪失是否是老年癡呆癥,一項新的研究表明，不是遺忘，而是沒有意識到我們的健忘讓人們感到害怕。 （1）考查推理判斷。根據(jù)第一段中的“In our twenties, we find it funny when we can39。t remember our neighbor39。s cat39。s name or a handsome actor who starred in a famous movie. In our thirties, we jokingly call it ‘brain freeze’ In our forties, we laugh it off as a‘senior moment’ and follow up with one of these old age jokes. But the reality is that there es a point when being forgetful stops being funny and starts to seem a bit dreadful. ”在二十多歲的時候，當(dāng)我們記不起鄰居的貓的名字或是主演一部著名電影的英俊演員時，我們覺得很有趣。在三十多歲的時候，我們開玩笑地稱它為“大腦凍結(jié)”，在四十多歲的時候，我們把它當(dāng)作“老年時期”來嘲笑，然后繼續(xù)講這些老年笑話。但現(xiàn)實是，有這樣的時候，健忘不再有趣，而且看起來有點可怕，可推知選A。 （2）考查細節(jié)理解。根據(jù)第二段中的“ The fact that you recognize your own forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimer39。s disease（AD） ”承認自己的健忘也許是一個很好的跡象，至少從你患老年癡呆癥,的可能性來看，可知選C。 （3）考查細節(jié)理解。根據(jù)第四段中的“ It is an objective marker of the sort of reduced brain function that goes along with expected, glucose uptake was reduced in those with AD. ”這是一個患有老年癡呆癥降低了腦功能的客觀標(biāo)志。正如所料，老年癡呆癥患者的葡萄糖吸收降低，故選B。 （4）考查推理判斷?？v觀全文可知，是一項科學(xué)研究，介紹了如何預(yù)測你的記憶喪失是否是老年癡呆癥,故選C。 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確掌握細節(jié)信息，并根據(jù)上下文進行邏輯推理，從而選出正確答案。4．閱讀理解 Learning, Fast and Deep Over the past five years researchers in artificial intelligence have bee the rock stars of the technology world. 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?
