22、f work done.”，可知，产品的分配是按照所干活的量(amount of work done)来决定的。3D 推理判断题。由第五段“We live in an arable area but we often do not know our farmers.This is a brilliant way of pulling people together，she said.She hopes to get her two teenage sons involved.”可知，Claire对菜园项目持支持态度。故选D项。4A 词义猜测题。由最后一段可知三个当地农民迫不及待地让出自己的土地
23、，说明Walston的想法已经成功激励了更多的人参与项目，由此可知prompted的意思是“激励”。故选A项。.七选五根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。How to Eat Better for the PlanetIs it possible to have a diet thats both healthy and friendly to our planet?Here are answers to your ecofriendly food questions.Does what I eat have an effect on climat

29、uarter of the planetwarminggreenhouse gases that humans generate each year.”可知，本段在讲人类的食物系统是怎样产生温室气体的；上句“That includes raising and harvesting all the plants,animals,and animal products we eat.”告诉我们：这个食物系统包括饲养和收获各种植物、动物及动物产品，所以，E项“加工、包装和运输食物也是其中一部分”符合语境。2G 本空承接上文。上句告诉我们：当一些森林为农场、牛、羊或其他家畜让地方而被清除时，一些很严重
30、的问题就出现了。本空承接上文，因此可推出，接下来讲“严重的问题是什么”，所以G项“被排放到大气层中的大量二氧化碳就会使地球变暖”符合语境。故选G。3D 由本段大意可知，本段主要讲述“鸡”的影响；再根据本空上一句，“A number of studies have found that chickens,ducks,and other birds have a lesser climate impact than cattle or sheep kept on a farm”，本空承接上文，因此可推出，接下来应该讲“鸡是怎样更小地产生影响的”，所以D项“Modernday chickens ar
31、e bred to be extremely efficient”符合语境。故选D。4C 本空承接上文。由本段大意可知，本段主要讲述“有机耕种”的影响；再根据本空上一句“but that doesnt mean its necessarily better than conventionally grown produce from a climate perspective”，本空承接上文，本空讲有机耕种的缺点，所以C项“有机耕种需要更多土地”符合语境。5B 这是一个主题句。由上文主题句的形式可知，答案确定在前两项中。由下文中“Its true that one person alone just makes a little bit in the climate problem.On the other hand,if many people made changes to their diets,that could start to add up.”可推出，作者在号召所有人都做出努力，故B项“我真的可以起到作用吗？”符合语境。
