The world’s cities produce 2 billion tons of trash every year. By the year 2050 that number is expected to rise to 3 billion tons. The World Bank estimates that the largest amount of trash today,about 44 percent,is plastic. But we often have to buy packaged goods. And often that packaging is made of plastic. Now,that may be changing. A new environmentallyfriendly shopping model was launched at the World Economic Forum in Davos,Switzerland. This shopping model,called Loop,aims to replace throwaway containers with reusable ones. Loop is the idea of Terra Cycle,an Americanbased recycling pany. Its chief,Tom Szaky told the Associated Press (AP) that “removing plastics from the ocean is not enough. ” He said the point is to get away from singleuse packages. Szaky said that Loop is the future of shopping. But it es from an idea of the past. He pared it to the “milkman model” of the 1950s in the United States. Back then,someone brought milk to your doorstep in glass bottles and then left with empty bottles. These could be cleaned and used again. The result is zerowaste. Jennifer Morgan from the environmental nonprofit organization Greenpeace also joined in the discussion about Loop at Davos. She said that “Greenpeace weles the aim of the Loop Alliance to move away from throwaway culture and disposability. ” But Morgan questioned whether panies worldwide are ready to change their business models. Loop is set to launch later 2019 in three eastern U. S. states,and also in Paris,France and some of the surrounding areas. Then Loop plans to expand to the U. S. West Coast,Toronto,Canada and Britain by 2020. 【語篇概述】本文是一篇環(huán)境保護類短文。24. What does the author intend to do in Paragraph 2?A. Provide background information. B. Advocate zerowaste lifestyle. C. Explain the reason for trash. D. Introduce a new topic. 【解析】選A。根據(jù)文章第二段The world’s cities produce 2 billion tons of trash every year. By the year 2050 that number is expected to rise to 3 billion tons. The World Bank estimates that the largest amount of trash today,about 44 percent,is plastic. But we often have to buy packaged goods. And often that packaging is made of plastic. 可知,世界上的城市每年產生大量的垃圾,并且其中數(shù)量最大的垃圾是塑料,結合下文可知,作者寫本段目的是為下文提出新的購物模式提供背景信息。25. Where does the idea “Loop” e from?A. The World Economic Forum. B. Demand of some panies. C. Zerowaste model. D. Jennifer Morgan. 【解析】選C。根據(jù)文章第四段Szaky said that Loop is the future of shopping. But it es from an idea of the past. 和第五段He pared it to the “milkman model” of the 1950s in the United States. Back then,someone brought milk to your doorstep in glass bottles and then left with empty bottles. These could be cleaned and used again. The result is zerowaste. 可知,Loop購物模式的想法來自過去的“送奶工模式”,是一種零浪費的模式。26. Which countries is Loop expected to expand to by 2020?A. United States and Switzerland. B. Switzerland and Britain. C. Canada and Britain. D. France and Canada. 【解析】選C。根據(jù)文章最后一段Loop is set to launch later 2019 in three eastern U. S. states,and also in Paris,France and some of the surrounding areas. Then Loop plans to expand to the U. S. West Coast,Toronto,Canada and Britain by 2020. 可知,Loop計劃在2020年將業(yè)務擴大到加拿大和英國。主旨大意題。故選A。RMIT大學的研究人員發(fā)現(xiàn)了蜜蜂能做基本的數(shù)學運算。發(fā)表在《科學進展》雜志上的這項新研究將蜜蜂也列入了這一名單。細節(jié)理解題。故選D。A. requires addition and subtraction two plex processingB. has a possible effect on the future development of AIC. only involves their shortterm working memoryD. calls for a lot of maths knowledge【解析】選B。根據(jù)第五段“If math doesn’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,”“如果數(shù)學不需要一個巨大的大腦,那么在設計中,我們也可能有新的方法來包括長期規(guī)則和工作記憶的互動,從而提高人工智能對新問題的快速學習,”可知,Adrian Dyer認為,蜜蜂的數(shù)字認知對人工智能的未來發(fā)展可能有影響。30. What does the finding of the new research suggest?A. Bees can recognize the exact number. B. Arithmetic operations exist in human and bees. C. Numerical cognition has been found in many more species. D. Some primates,birds and even spiders can add and subtract. 【解析】選C。根據(jù)倒數(shù)第二段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。”可知,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。31.

As a result,the survival of some species of wildlife is threatened. To help protect wildlife,a lot of practices should be carried out by environmentalist as well as the general public. 　　Create homes for species that are endangered because of losing their own natural habitats. Wildlife shelters should be developed,and habitats should be created in existing(現(xiàn)存的) national parks. Efforts(努力) should also be made to protect existing habitats,such as providing food and wat
