问题 In the opening paragraph, the author introduces his topic by ______.
In the last paragraph, the author cites the nutritionists’ words to show that ______.

选项 A、people in the richest countries consume more meat than that is necessary for health
B、meat consumption may cause an ecological disaster
C、nutrition in meat is not as good as other kinds of food
D、grains are wasted if people don’t eat meat

答案A

解析 由题干the author cites the nutritionists’ words to show定位到原文最后一段最后一句...don’t need nearly as much protein as we’re currently getting from meat....细节题。该句意为:但是营养学家们证实在那些最富裕的国家中,大多数人并不需要我们现在从肉类食品中所摄取的这么多的蛋白质,而且有充足的植物来源一包括现在被浪费在饲料上的谷物—可提供我们所需的蛋白质。句中... don’t need nearly as much protein as we’re currently geeing from meat...是A)的同义转述,故选A)。[避错]文章虽有肉类消费可能引起生态灾难的意思,但具体营养学家的这儿句话是为了证明目前人类大可不必消耗如此大量的肉类,排除B);该句后半部分there are plenty of vegetable sources...that can provide the protein we need说明植物一样可提供我们所需的蛋白质,并没有肉类营养不如其他食品好的意思,排除C);文章主题是反对人们吃肉,D)与文意相悖。
