Question

    Experts say that food is one of the biggest greenhouse gas polluters. The reason is the rising demand for meat. Animal farming is responsible for 14.5 percent of global greenhouse gas methane emissions. While cows are the worse contributors, pigs, sheep, donkeys and other animals play a part as well.

Animal farming also causes land to become damaged, water to be polluted and forests to get destroyed. That is why experts are advocating substituting some of the beef, chicken, or pork with ordinary insects!

Insects, which grow into adults within a matter of months, if not weeks, are ready for consumption much faster than domestic animals. They also require much less room, use less water and food, and produce far less greenhouse gas than animals.

Of the 1.1 million insect species worldwide, scientists have identified 1.700 as eatable. Among them are ants, grasshoppers, grubs, and earthworms. Just like animals, each insect has a different taste. Tree worms taste just like pork, and grubs are similar to smoked meat.

While eating insects might be a new concept for Western people, over 2 billion people worldwide consume insets as a regular part of their diet. Besides being delicious, insets are high in protein, have very few calories, and are free of the saturated fat. So eat insects, both your body and Mother Earth will thank you for it!

【解析】

这是一篇说明文。专家表示，食物是最大的温室气体污染源之一。原因是对肉类需求的增长。畜牧业排放的温室气体甲烷占全球总量的14.5%。畜牧业也导致土地被破坏，水被污染，森林被破坏，所以专家们提倡用普通昆虫代替一些牛肉、鸡肉或猪肉。文章主要说明了将昆虫作为食物的一些优势。

1.

细节理解题。根据第一段中Animal farming is responsible for 14.5 percent of global greenhouse gas methane (甲烷) emissions (排放). While cows are the worse contributors, pigs, sheep, donkeys and other animals play a part as well.可知畜牧业排放的温室气体甲烷占全球总量的14.5%。虽然牛是更糟糕的贡献者，但猪、羊、驴和其他动物也起到了一定的作用。由此可知，奶牛是全球甲烷排放量最大的动物。故选C。

2.

推理判断题。根据第三段Insects, which grow into adults within a matter of months, if not weeks, are ready for consumption much faster than domestic (驯养的) animals. They also require much less room, use less water and food, and produce far less greenhouse gas than animals.可知昆虫能在几个月甚至几周内长成成虫，它们可以比家畜更快地供人食用。与动物相比，它们需要更少的空间，使用更少的水和食物，产生更少的温室气体。由此可推知，第三段将昆虫和家畜进行比较，主要是通过比较展开的。故选D。

3.

细节理解题。根据倒数第二段中Tree worms taste just like pork, and grubs are similar to smoked meat.可知树虫吃起来就像猪肉，幼虫也像熏肉。由此可知，树虫吃起来像煮肉。故选A。

4.

推理判断题。根据最后一段中Besides being delicious, insets are high in protein, have very few calories, and are free of the saturated (饱和) fat.可知除了美味之外，燕窝还富含蛋白质，热量很低，而且不含饱和脂肪。由此可推知，燕窝是健康的食材，但是不含饱和脂肪，说明饱和脂肪对健康有害。故选C。
