【文章內(nèi)容簡(jiǎn)介】 Overall, in high173。ine countries, Behren39。s team estimates that following the rules could result in as much as a 17 percent reduction in land use, a 21 percent reduction in nutrient pollution, and a 25 percent drop in agricultural greenhouse gas emissions. Cutting down on how much food we waste—which is roughly a third in the US—could help even more. The results are in the Proceedings of the National Academy of Sciences. Of course, people are notoriously bad at following diets. But: These nationally remended guidelines do actually have a knock173。on effect on other areas of policy making. So if I39。m developing a new healthy173。eating173。for173。schools program then that39。s going to be based off a lot of detail that I get from the nationally remended guidelines. So while it might not necessarily be the case that people follow directly …they actually are quite influential on the preparation of other advice. It seems that a smaller environmental footprint and a healthier lifestyle could go hand in hand.（1）Which of the following statement will Paul Behrens approve of? A.Following a nationally remended diet can have similar impacts in different countries.B.Following a nationally remended diet can do good to our health.C.Not all the countries have remended diets in an explicit manner.D.Some high173。ine nations don39。t mention the diet explicitly for its impacts can be ignored.（2）What do the underlined words takes a big toll on in paragraph 3 probably mean? A.shows signs ofB.has a bad effect onC.takes full advantage ofD.makes up for（3）Which of the following is TRUE according to the passage? A.Food production can lead to about 20 percent of human173。caused greenhouse gas with only a third of the ice173。free land used.B.It is estimated that following dietary guidelines can lead to decrease in more land use than in nutrient pollution.C.Paul Behrens39。 new program concerning healthy eating for schools is likely to be based on national nutrition guidelines.D.Some wealthy countries tend to reduce meat and dairy though the other areas of policy making isn39。t effected much.【答案】 （1）C（2）B（3）A 【解析】【分析】本文是一篇說明文，介紹了營(yíng)養(yǎng)指南對(duì)地球也有利。通過膳食指南，似乎可以減輕對(duì)環(huán)境的傷害，人類自己也可以過上健康的生活，二者可以兼得。 （1）考查推理判斷。根據(jù)第二段中的 What we found is that impacts vary across nations, but in the high173。impact nations, in general, you can see that, if you follow a nationally remended diet, despite the fact that these diets don39。t mention explicitly—or most of them don39。t explicitly mention—environmental impacts, that you are going to have lower environmental impacts due to that.” 我們發(fā)現(xiàn)（營(yíng)養(yǎng)膳食指南的）影響因國(guó)家而異，但總的來說，在影響力較大的國(guó)家，如果你遵循國(guó)家推薦的膳食指南，即使這些膳食并未明晰對(duì)環(huán)境的影響，或者大多數(shù)膳食沒有明確說明這一點(diǎn)，但是你對(duì)環(huán)境的影響會(huì)因?yàn)樽裱改隙鴾p輕。由此推斷出 并非所有國(guó)家都以明確的方式推薦飲食 ，這個(gè)觀點(diǎn)Paul Behrens會(huì)贊成，故選C。 （2）考查詞義猜測(cè)。根據(jù)第三段中的“A third of the ice173。free land on Earth is used for agriculture, and according to some estimates, producing food accounts for roughly a fifth of all human173。caused greenhouse gas emissions. Fertilizer runoff also leads to other problems, like the algae blooms in Lake Eerie and the Dead Zone in the Gulf of Mexico.”地球上三分之一的無冰區(qū)被用于農(nóng)業(yè)生產(chǎn)，根據(jù)一些估算，食物生產(chǎn)大約占到了人類造成的溫室氣體排放量的五分之一。肥料徑流也導(dǎo)致了其他問題，例如伊利湖的藻類爆發(fā)以及墨西哥灣的死亡區(qū)域。由此推斷出劃線詞所在的句子意思是我們所吃的食物給環(huán)境帶來了巨大代價(jià)。takes a big toll on固定短語(yǔ)，“付出了巨大的代價(jià)”，故選B。 （3）考查細(xì)節(jié)理解。根據(jù)第三段中的“A third of the ice173。free land on Earth is used for agriculture, and according to some estimates, producing food accounts for roughly a fifth of all human173。caused greenhouse gas emissions.”地球上三分之一的無冰區(qū)被用于農(nóng)業(yè)生產(chǎn)，根據(jù)一些估算，食物生產(chǎn)大約占到了人類造成的溫室氣體排放量的五分之一。由此可知。A選項(xiàng)的描述 糧食生產(chǎn)可導(dǎo)致約20%的人為造成的溫室氣體，而只使用了三分之一的無冰土地 正確，故選A。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測(cè)和推理判斷三個(gè)題型的考查，是一篇科研類閱讀，要求考生準(zhǔn)確捕捉細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。5．犇犇閱讀理解 Environmental experts warn that our planet is drowning in plastic. The world39。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 recently 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 this year in three eastern . states, and also in Paris, France and some of the surrounding area. Then Loop plans to expand to the . West Coast, Toronto, Canada and Britain by the end of this year or 2020.（1）What does the author intend to do in Paragraph 2?
