【文章內容簡介】 o 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胞，暫時停止運作是可以的。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)。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. 可知老人們更加關注生活中積極的事物，是為了增強他們的免疫功能。也就是說積極與免疫功能之間有關系，越積極，免疫功能越強，就能活得越久，所有選項中D項（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.可知當我們快樂時，我們的免疫系統(tǒng)進化到最大程度，但是當我們不快樂時，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注積極的事情，后文提到積極的情緒會增強免疫系統(tǒng)，所以本文主要講的是年齡，健康與積極的情緒之間的關系，選B。 【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(jù)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。4．犇犇Choose the one that fits best according to the information given in the passage you have just read. The Rapid Rise and Fall of Robot Babysitters During the winter of 2017, an 18year old college student named Canon Reeves spent much of his time trailing a kneehigh robot around Fayetteville, Arkansas, as it delivered Amazon packages to students. The robot, created by a startup called Starship Technologies in 2014, is basically a cooler on wheels。 it uses radars, sensors, and nine cameras to make deliveries. Reeves39。s job was to monitor how it handled various grounds, field ments from the public, and press the off switch if necessary. He said, People would also ask if it could deliver beer. It couldn39。t. Broadly speaking, jobs of caring for robots fall under the umbrella of careers in automation, which include maintenance, engineering and programming. The demand for people with this skill set is considerable, with 20 million to 50 million new jobs to be expected in this category by 2030, according to the Mckinsey Global Institute. In the year that ended in June 2018, had almost three times the number of positions on the recruitment mittee that ended in June 2016. Over the last year, a 34yearold businessman named David Rodriguez spent hundreds of hours following a machine called the KiwiBot around UC Berkeley39。s campus while it delivered Red bull and other drinks to students. To retrieve (檢索) orders, the app encourages students to give the robot a wave。 the robot39。s digital eyes will roll depending on its mood. Rodriguez, who heads business development for the startup, was tasked, early on, with monitoring the KiwiBot for problems – even carrying it, should the motors fail. Since April 2018, though, the KiwiBot has largely been left unattended, and the majority of human interactions involve technical checks and loading food into the robot. To eliminate the boring work, the team is developing a restaurant robot to collect and load orders – which could happen in 2020. However, Rodriguez assured me that his staff won39。t be out of work. Everyone holds double roles in the pany. Greater robot selfgoverning just means employees will shift their focus to accounting, engineering, and design. Mckinsey estimates that millions of jobs globally could be lost to automation by 2030. A huge number of jobs will be produced as autonomous vehicles are released into the environment, Ramsey said. In 2016, Bosch started training students from Schoolcraft College, a munity college in Michigan, in autonomousvehicle repair。 Toyota has trained students in maintenance as well. We might even see a return to lowlevel jobs where people e and fuel the car for you, Ramsey said. Until we can wirelessly charge, someone needs to refuel them. The hardesttoautomate industries, as it happens, are the ones that require looking after humans, such as childcare, education and health care. Robot babysitters might feel like they have scored the job of the future, but in fact, they might be better positioned.（1）What kind of robot is the one created by a startup called Starship Technologies?
