【正文】 will speed up metabolic processes to answer itC.immune system will temporarily shut down to fulfill itD.brain will satisfy it by sharing optional metabolic output（2）In paragraph 3 this relationship most probably refers to the one between ______. A.experiences and related knowledgeB.happiness and biological evolutionC.immune function and healthD.optimism and length of life（3）What can be concluded from Robert Trivers39。 study? A.Younger people adopt strategies of handling tense situations from everyday life.B.Our ancestors evolved their immune systems in fighting against fierce animals.C.Realizing that their days are numbered, older people prefer being positive.D.Being negative drains energy from our body, lowering resistance to disease.（4）Which of the following is the best title of the passage? A.Brain, muscles and immune systemB.Age, health and happinessC.Ancestors, emergency and evolutionD.Energy, effort and response【答案】 （1）C（2）D（3）D（4）B 【解析】【分析】本文是一篇說明文，研究表明，老年人往往會記住生活中積極的事物，而不是消極的事物。十年前作者與生物學(xué)家羅伯特特里弗斯合作研究身體是如何使用能量的，他們的發(fā)現(xiàn)解釋了這一現(xiàn)象。 （1）考查推理判斷。根據(jù)第二段中的“We have an enormous number of immune cells coursing through our body, a momentary break from production is fine. So, when our body needs extra energy, one of the places it goes is our immune function.”可知我們的身體里有大量的免疫細(xì)胞，暫時停止運(yùn)作是可以的。因此，當(dāng)我們的身體需要額外的能量時，（我們的身體）會去找免疫系統(tǒng)。由此可以推斷，免疫系統(tǒng)會暫時停止來為身體提供額外的能量。選C。 （2）考查詞義猜測。根據(jù)第三段中的 being more focused on the positive things in life in an effort to enhance their immune functioning. 可知老人們更加關(guān)注生活中積極的事物，是為了增強(qiáng)他們的免疫功能。也就是說積極與免疫功能之間有關(guān)系，越積極，免疫功能越強(qiáng)，就能活得越久，所有選項(xiàng)中D項(xiàng)（樂觀與壽命）之間最切題，故選D。 （3）考查推理判斷。根據(jù)最后一段中的As a result, our immune system evolved to run in maximum amounts when we39。re happy, but to slow down dramatically when we39。re not.可知當(dāng)我們快樂時，我們的免疫系統(tǒng)進(jìn)化到最大程度，但是當(dāng)我們不快樂時，免疫系統(tǒng)會減弱。由此推斷，消極會消耗我們身體的能量，降低對疾病的抵抗力。選D。 （4）考查主旨大意。作者開頭提出老年人更關(guān)注積極的事情，后文提到積極的情緒會增強(qiáng)免疫系統(tǒng)，所以本文主要講的是年齡，健康與積極的情緒之間的關(guān)系，選B。 【點(diǎn)評】本題考點(diǎn)涉及推理判斷，詞義猜測和主旨大意三個題型的考查，是一篇科研類閱讀，考生需要根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。7．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?
