问题     Every second in the United States alone, more than 250 animals are slaughtered for food, adding up to more than 8 billion animals each year. Reducing the amount of meat in one’s diet is nutritionally, environmentally, and ethically beneficial.
    People who eat meat usually have weaker immune systems compared to those of vegetarians. Meat has been directly linked to diabetes, obesity, arthritis, and many other illnesses. Furthermore, meat-eaters are at a higher risk for diseases, including cancer, and they are more likely to die from these diseases. Critics say that a meatless diet does not provide enough nutrients, especially protein and iron. Actually, according to A Teen’s Guide to Going Vegetarian, by Judy Krizmanic, protein is found in almost every food, and iron appears in many vegetables. Getting enough nutrients in a meat-reduced diet should not be difficult. A 1988 study found that some of the highest pesticide residues appear in meat and eggs. Diets including more fruits and vegetables will only make people healthier.
    Some skeptics believe that there will be a shortage of food if animals are not eaten. In fact, the opposite is true. More than 80% of the corn and 95% of the oats grown in the US are fed to livestock. The world’s cattle alone consume enough food to equal the caloric needs of 8.7 billion people, more than the entire human population. One half of the water used in the Unites States also goes to livestock; 2.50 gallons of water produces only 1 pound of beef. If people eat less meat and more plants, the amount of available food will increase.
    Many people become vegetarians because they feel that eating animals is unethical. 90% of these animals are raised in confinement. Chickens and other birds have only about half. a square foot of space each, and since they are raised so close together, a hot blade is used to cut off their beaks to prevent them from pecking each other to death. Likewise, pigs that are repressed will bite each other’s tails, so both their teeth and tails are removed as soon as they are born.
    Eating animals is hazardous in numerous ways. Even a slight reduction in meat intake is better than nothing at all. Consuming less meat is beneficial to the health of animals, the health of people, and to the health of the world.
In the third paragraph, the author implies that
选项 A、food will be insufficient if animals are not eaten.
B、lots of food and water are consumed by cattle.
C、a meat-reduced diet is environmentally beneficial.
D、animals are raised for human food.
答案C
解析 推理判断题。作者在第三段用具体的例子来证明观点，而且用具体的数字来增加事例的可信度。这一段讲的是人们喂养牲畜消耗大量食物和水，如果少吃肉的话，我们的食物将绰绰有余。[A]是some skeptics的观点，也是作者要驳斥的观点，予以排除；[B]项范围太窄，cattle只是一例；[C]“减少了肉类的饮食对环境有好处”正确，全文主旨句即第一段第二句话提到“减少膳食中的肉类摄入从营养、环境和道德伦理上来说都有益无害”，接下来的三段分别从营养、环境和道德伦理三个方面具体阐述，因此第三段讲的是[C]； [D]离题较远。
