【正文】 考查細節(jié)理解。由此可推斷出對于艾滋病的治療迫在眉睫，非常緊迫。根據(jù)第三段中的“nearly 37 million people were living with HIV in 2017.... Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease” 可知，“2017年全世界有近3700萬人感染艾滋病毒。研究人員表示，這一“突破性”的發(fā)現(xiàn)是“現(xiàn)在唯一的”以低成本為發(fā)展中國家生產(chǎn)抗艾滋病毒聯(lián)合治療的方法，但還有待于進一步的完善。A social webpage.D.A biology textbook.B.It still requires perfecting.D.It can prevent infections of HIV.B.By attaching it to the HIV virus.D.By transforming it into proteins.B.Remind readers of HIV prevention.D.Stress the urgency of HIV treatments.B. They say the easiest and most costeffective way to use the rice will be to make it into a cream to be put on the skin. The HIVfighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves. This would prevent the cost and travel required for many patients to receive treatments and medicine. The Joint United Nations Program on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017. The organization says the largest number of those are in developing countries. Nearly twothirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease. According to a recent study, a new genetically modified rice can prevent infections of HIV, the virus responsible for the disease AIDS. 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科研類閱讀，要求考生在捕捉細節(jié)信息的基礎(chǔ)上，進一步根據(jù)上下文的邏輯關(guān)系，進行分析，推理，概括和歸納，從而選出正確答案。發(fā)表在《科學進展》(Science Advances)雜志上的這項新研究將蜜蜂也列入了這一名單。 （4）考查主旨大意?？芍?，新研究的發(fā)現(xiàn)說明了在更多的物種中發(fā)現(xiàn)了數(shù)字認知。根據(jù)倒數(shù)第二段中的“Many species can understand the difference between quantities and use this to search for food, make decisions and solve problems. But numerical cognition, such as exact number and arithmetic operations, requires a more plex level of processing.”許多物種都能理解數(shù)量之間的差異，并以此來尋找食物、做出決定和解決問題。故選B。根據(jù)第五段中的“If math doesn39。故選D。”可知，RMIT大學 的 （1）考查細節(jié)理解。此前的研究表明，一些靈長類動物、鳥類、嬰兒甚至蜘蛛都可以加減法。Numerical Cognition Requires a Complex Level of ProcessingD.A Discovery About the Tiny Brain of BeesB.Numerical cognition has been found in many more species.D.Bees can recogize the exact number.B.only involves their shortterm working memoryD.requires addition and subtraction two plex processingB.Bees can do basic mathematics.（2）According to Adrian Dyer, bees39。Longterm rules and short term working memory.C. Previous studies have shown some primates (靈長目動物), birds, babies and even spiders can add and/or subtract. The new research, published in Science Advances, adds bees to that list.（1）What have the researchers from RMIT University discovered? A.t require a massive brain, there might also be new ways for us to include interactions of both longterm rules and working memory in designs to improve rapid AI learning of new problems,” said Dyer. The findings suggest that advanced numerical cognition (認知) may be found much more widely in nature among nonhuman animals than previously suspected. RMIT39。 Researchers have found bees can do basic mathematics, in a discovery that deepens our understanding of the relationship between brain size and brain power. Recently, A study conducted by researchers from RMIT University in Melbourne, Australia showed that bees could perform arithmetic operations like addition and subtraction (減法). 【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，是一篇科教類閱讀，考生需要準確掌握細節(jié)信息，同時根據(jù)上下文進行邏輯推理，從而選出正確答案。由此可推斷出，我們鼓勵孩子去贏的同時，提醒他們要體諒他人。 （4）考查推理判斷。由此可推斷出，人們天生不喜歡不友善的行為。 （3）考查推理判斷。根據(jù)第二段中的“Asked which puppet they liked better, 18 of the 21 toddlers in the experiment reached for the puppet who had been allowed to pass. Because respect from others is a marker of status, this suggests that children have a preference for those with a higher status—even before age three.”可知，蹣跚學步的孩子喜歡那個被允許通過的木偶，是因為這種行為代表著受人尊敬，孩子們更喜歡受尊敬的人。故選B。根據(jù)第一段中的“A recent study published in Nature Human Behaviour showed that we seem to have an innate（天生的）preference for highranking peoples—but only if those people aren39。ll keep reminding him that helping his brother so they both finish faster is what winning is all about.（1）What do we tend to do according to the first paragraph? challenges all the time. highranking people. advantage of high status. others with offensive words.（2）Why did toddlers prefer the puppet allowed to pass? looked adorable. behaved smartly. seemed polite. was respected.（3）What can we infer from the latter study? people are better loved by toddlers. naturally dislike unkind behavior. care little about high social status. helpful contributes to being supported.（4）What should we do when we encourage children to win? them to use proper and creative ways. them to be as hardworking as possible. them to be considerate to other people. them to try to cooperate with someone else.【答案】 （1）B（2）D（3）B（4）C 【解析】【分析】本文是一篇說明文，介紹了人們更傾向于喜歡和尊敬地位高而又無害于他人的人，這似乎是一種天性，即使是蹣跚學步的孩子也是如此。 However, the results were quite different when two puppets approached one another and one used force to knock the other down before continuing to the other side. In this case, 18 of the 21 toddlers reached for the one who was knocked down. As the researchers concluded, When approaching others, very young children care not only who wins, but also how. The previous experiment has shown that toddlers know about social status, but this experiment went one step further by proving they have an obvious preference for high status. Since the participants were so young, this might even be an innate human preference.t hurtful toward others.re racing their bikes down the sidewalk or just finishing their snacks.
