【正文】 rs better measure Greenland39。s past and future climate. Just beyond the northwest edge of the vast Greenland Ice Sheet, researchers have discovered lake mud that have survived the last ice age. The mud, and remains of mon flies in it, record two interglacial periods(間冰期)in northwest Greenland.5．Directions: Choose the one that fits best according to the information given in the passage you have just read. 故選A。該劃線句子的字面意思是：機(jī)器人保姆可能會(huì)覺(jué)得自己已經(jīng)獲得了未來(lái)的工作，但事實(shí)上，他們的位置可能會(huì)更好。故選C。 （3）考查細(xì)節(jié)理解。 （2）考查詞義猜測(cè)。也就是說(shuō)，Starship Technologies公司創(chuàng)造的是一款配送物品的機(jī)器人。根據(jù)第一段中的The robot, created by a startup called Starship Technologies in 2014, is basically a cooler on wheels。本文以對(duì)相關(guān)信息進(jìn)行了介紹說(shuō)明。We still need someone to look after robots in the future.D.Robot carers will have a petitive advantage in the future.B.A lot of job opportunities will be created.D.Autonomous vehicles will bee much cheaper.B.D.are in relation ofB.are in the category ofD.A restaurant robot.B.A factory robot. 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。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。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。 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.

The robot, created by a startup called Starship Technologies in 2014, is basically a cooler on wheels。 【點(diǎn)評(píng)】本題考點(diǎn)涉及推理判斷，詞義猜測(cè)和主旨大意三個(gè)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。 （4）考查主旨大意。由此推斷，消極會(huì)消耗我們身體的能量，降低對(duì)疾病的抵抗力。re happy, but to slow down dramatically when we39。 （3）考查推理判斷。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。選C。因此，當(dāng)我們的身體需要額外的能量時(shí)，（我們的身體）會(huì)去找免疫系統(tǒng)。 （1）考查推理判斷。十年前作者與生物學(xué)家羅伯特D.Age, health and happinessC.Being negative drains energy from our body, lowering resistance to disease.（4）Which of the following is the best title of the passage?

A.D.immune function and healthB.brain will satisfy it by sharing optional metabolic output（2）In paragraph 3 this relationship most probably refers to the one between ______. A.organs will speed up metabolic processes to answer itC.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. As a result, our immune system evolved to run in maximum amounts when we39。t need to waste energy making immune cells to fight off tomorrow39。 When our ancestors needed more energy than usual, perhaps while being chased by a tiger, they had to get that energy from somewhere in the body. Could they borrow it from the brain? That organ uses 20 percent of our metabolic (新陳代謝) output, whether we are solving math problems or watching television reruns. Due to this constant energy requirement, borrowing energy from the brain when our need surpasses the available supply is not an option. Perhaps we could borrow energy from our muscles. Because we use far more muscle energy when we are active than when at rest, in principle, we could borrow energy when we are sitting. But the problem is that most of the energydemanding 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。 Studies show that older people tend to remember the positive thi
