Question

    Experts say that if food were a country, it would rank second behind the US as one of the biggest greenhouse gas polluters. The reason is the rising demand for meat. Animal farming is responsible for14.5 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.

Animal agriculture also causes land to become damaged, water to be polluted and forests to get destroyed. With the world population forecast to rise to 9.8 billion by 2050, things are only looking worse for our already decreasing natural resources, While going vegetarian(素食的)would help meat consumption too deep - rooted in most western diets to allow for such a sharp, permanent change. 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(驯养的) 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 insects as a regular part of their diet. Besides being delicious, insects are high in protein, have very few calories, and are free of the saturated(饱和)at found in animal meat. Insects can be prepared in many ways. Creative cooks can use them to cook protein-rich soup make baked treats, and even fry a few with vegetables. So eat insects -both your body and Mother Earth will thank you for it ！

【解析】

本文为说明文。专家表示，如果食品是一个国家，它将排在美国之后，成为全球第二大温室气体排放国之一。原因是对肉类的需求不断增长。畜牧业占全球温室气体甲烷排放量的14.5%。畜牧业也导致土地被破坏，水被污染，森林被破坏。因此一些专家提倡用昆虫替代一些牛肉、鸡肉或猪肉。文章介绍了专家提议的理由和依据。

1.细节理解题。根据第一段中的While cows are the worse contributors, pigs, sheep, donkeys and other animals play a part as well.可知，牛是畜牧业中排放温室气体甲烷最多的动物。故A选项正确。

2.推理判断题。根据第三段中的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.可知，本段主要对昆虫和家畜进行了对比说明。故D选项正确。

3.细节理解题。根据倒数第二段中的Tree worms taste just like pork, and grubs are similar to smoked meat可知，树蠕虫的味道就像猪肉一样，幼虫和熏肉相似。故A选项正确。

4.推理判断题。根据最后一段中的Besides being delicious, insects are high in protein, have very few calories, and are free of the saturated at found in animal meat…So eat insects -both your body and Mother Earth will thank you for it！可推可知，饱和脂肪对健康有害。故C选项正确。
