【正文】 rgydemanding emergencies of our ancestors required a muscular response. There was no way to borrow energy from our muscles during an emergency because relaxing when a tiger showed up was not an effective response. This brings us to our immune system, which, when strong, protects us from many illnesses and diseases. Like the brain, the immune system works at great metabolic cost, but largely in the service of keeping us healthy in the future. 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. When you39。t need to waste energy making immune cells to fight off tomorrow39。 As a result, our immune system evolved to run in maximum amounts when we39。re not. With this background in mind, Trivers supposed that older people evolved a strategy of turning this relationship on its head, being more focused on the positive things in life in an effort to enhance their immune functioning. This was helped along by their knowing much more about the world than younger adults, so they can deal with some of the unpleasant things in life more easily.（1）According to Robert Trivers, when our body needs extra energy, ______. A.organs will speed up metabolic processes to answer itC.brain will satisfy it by sharing optional metabolic output（2）In paragraph 3 this relationship most probably refers to the one between ______. A.B.immune function and healthD. study? A.Our ancestors evolved their immune systems in fighting against fierce animals.C.Being negative drains energy from our body, lowering resistance to disease.（4）Which of the following is the best title of the passage? A.Age, health and happinessC.D.十年前作者與生物學家羅伯特 （1）考查推理判斷。因此，當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)。選C。根據第三段中的 being more focused on the positive things in life in an effort to enhance their immune functioning. 可知老人們更加關注生活中積極的事物，是為了增強他們的免疫功能。 （3）考查推理判斷。re happy, but to slow down dramatically when we39。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。 （4）考查主旨大意。 【點評】本題考點涉及推理判斷，詞義猜測和主旨大意三個題型的考查，是一篇科研類閱讀，考生需要根據上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。 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.s top universities. Earning one takes years and requires a personality suited to academia, which is rare among more normal folk. 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。 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.

The Earth isn39。t grow after you die. The holes at the top of Bic biro pens are there so that, if you swallow one accidentally, you can still breathe and won39。s debatable whether that last one there is mon knowledge or not. A quick Google search of the fact, rewritten as a question, shows articles addressing this point going back several years, with the latest (re)appearing just this week over on ScienceAlert. We suppose it39。If you jump over to Bic39。 pens have a hole in their cap is to prevent the cap from pletely obstructing the airway if accidentally breathed in. This is requested by the international safety standards ISO11540, except for in cases where the cap is considered too large to be a choking risk. s rather lovely of them. In appreciation of their want to not kill off their more clumsy customers, we thought we39。The best part of the Bic site, however, is this rather curious fact: 100 percent of pen balls are made through a highlycontrolled process. As opposed to a highly uncontrolled process, involving explosions and bouncy castles and total chaos, we suppose.（1）Why does the author mention the case of Yellowstone? A
