The study was done with a variety of animals using phenomenon based on the maximum speed of flashes of light an individual can see before the light source is seen as constant. Dogs, for example, have eyes with a refresh rate higher than humans. Professor Graeme Ruxton of the University of St Andrews in Scotland, who worked jointly on the research project, said in a statement, Having eyes that send updates to the brain at much higher frequencies than our eyes do is of no value if the brain cannot process that information equally quickly. Thus, this work highlights the impressive abilities of even the smallest animal brains. Flies might not be deep thinkers, but they can make good decisions very quickly. s(獵物)position.

The new software is the first to continuously track and recognize individual a wide range of poses, performing with high accuracy in difficult conditions such as low lighting and poor image quality. The technology can be potentially used to monitor species for conservation Although the present application focuses on chimpanzees, the AI software provided will be applied to other species, and help drive the adoption of AI systems to solve(解決)a range of problems in the wildlife sciences.（1）What is the purpose of developing the new soft? save wildlife researchers39。 behaviors. protect chimpanzees and help them to live longer. recognize and track the faces of wild chimpanzees.（2）What does the underlined word it in paragraph 2 refer to? photos. videos. powerful machine new AI software.（3）What does paragraph 4 mainly talk about? working principle of the new software. limitations of using the new software. unique advantages of the new software. attitudes to the new software.（4）What can be known from the last paragraph? advance is the final goal of science new software won39。t easy.【答案】 （1）D（2）D（3）C（4）B 【解析】【分析】本文是一篇說明文，介紹了一種新的人工智能軟件，這種軟件可以識別和追蹤黑猩猩的面孔,大大節(jié)省了研究者和野生動物保護者的時間，而且它還可以應(yīng)用到其他的物種研究。根據(jù)第一段中的”Scientists at the University of Oxford have developed new artificial intelligence(AI) software to recognize and follow up the faces of chimpanzees(黑猩猩)in the wild. ”可知，新軟件的開發(fā)是為了識別和追蹤野外黑猩猩的面孔。 （2）考查代詞指代。故選D。根據(jù)第四段的敘述可知，本段主要介紹了新軟件與其他軟件相比所具有的獨特的優(yōu)勢。 （4）考查細節(jié)理解。故選B。4．閱讀理解 They took a % part together of the total global new leaf area between 2000 and 2017. China played a major role, adding 25% to this increase, and India added %, followed by Canada and Russia. The study in the Nature Sustainability journal shows that more than million square kilometers of green leaf area was added globally. Since 2000, there has been a fivepercent increase in global green cover, it said.s green cover, and agriculture added another 32%. In India, 82% of the increase in leaf area was because of agriculture.s land area covered in green plants, Chi Chen told NASA Earth Observatory. That is a surprising finding, considering the land degradation(退化) in countries with large populations.s research team first detected an increase in global green cover in the 1990s but were unsure about what contributed to the increase. Finally, with the help of NASA39。IndiaB.CanadaD.To show how great the achievement was.B.To explain what difficulties we have now.D.China and India have large populations and land degradation problemB.s greening is in China and IndiaC.the leaf cover area in China and India is still limited if viewed globally【答案】 （1）B（2）A（3）B 【解析】【分析】本文是一篇說明文，一項新研究顯示，中國和印度在改善全球樹木覆蓋方面處于領(lǐng)先地位?？紤]到人口眾多國家的土地退化，這是一個令人驚訝的發(fā)現(xiàn)。根據(jù)第二段中的“China played a major role, adding 25% to this increase, and India added %, followed by Canada and Russia.”中國扮演了主要的角色，增加了25%，%，加拿大和俄羅斯緊隨其后。故選B。根據(jù)第三段中的‘The greening over the last twenty years shows an increase in leaf area on plants and trees which is as large as the area of the entire Amazon rainforest,’ Chi Chen, a Boston University researcher and lead of the study told Nature Sustainability.“過去20年的綠化表明，植物和樹木的葉子面積增加了，相當于整個亞馬遜雨林的面積，波士頓大學(xué)研究員、該研究的負責人陳馳告訴《自然可知作者提到了亞馬遜雨林，以表明這一成就是多么偉大。 （3）考查細節(jié)理解。s land area covered in green plants,’ Chi Chen told NASA Earth Observatory.”陳馳告訴美國國家航空航天局地球觀測站:中國和印度占了地球綠化面積的三分之一，但卻只占地球陸地面積的9%。 【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，是一篇環(huán)保類閱讀，考生需要準確掌握細節(jié)信息，并根據(jù)上下文進行邏輯推理，從而選出正確答案。 For most of us, work is the central, dominating fact of life. We spend more than half our conscious hours at work, preparing for work, traveling to and from work. Wha
