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 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.

A.To prove sharing food increases petition.C.A meal taken in a family atmosphere.（2）For what purpose did the researchers carry out the present experiments? A.A meal consumed by oneself.B.A meal taken at home. The researchers measured cooperation by noting the number of rounds it took to reach an agreement, and found that those who shared food resolved the strike significantly faster（in 8. 7rounds）than those who did not（ rounds）. A similar experiment was conducted with 104participants and Goldfish crackers（餅干）, this time negotiating an airline39。 For the first test they recruited 100 pairs of participants from a local cafe, none of whom knew each other. The participants were seated at a table and fed tortilla chips with salsa. Half the pairs were given their own basket of 20 grams of chips and a bowl of 25 grams of salsa, and half were given 40 grams of chips and 50 grams of salsa to share. As a cover for the experiment, all participants were told this snack was to be consumed before the game began. Having conducted previous research in 2017 revealing that eating similar foods led to people feeling emotionally closer to one another, Dr Woolley and Dr Fishbach wondered whether the way in which food was served also had a psychological effect. They theorized that, on the one hand, sharing food with other people might indicate food scarcity（短缺）and increase a feeling of petition. However, they also reasoned that it could instead lead people to bee more aware of others39。3．犇犇閱讀理解 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。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。根據(jù)第三段中的“A third of the ice173。takes a big toll on固定短語，“付出了巨大的代價(jià)”，故選B。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。free land on Earth is used for agriculture, and according to some estimates, producing food accounts for roughly a fifth of all human173。 （2）考查詞義猜測(cè)。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。impact nations, in general, you can see that, if you follow a nationally remended diet, despite the fact that these diets don39。 （1）考查推理判斷。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。 new program concerning healthy eating for schools is likely to be based on national nutrition guidelines.D.It is estimated that following dietary guidelines can lead to decrease in more land use than in nutrient pollution.C.caused greenhouse gas with only a third of the ice173。makes up for（3）Which of the following is TRUE according to the passage?
