单选题 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.

单选题 Which of the following is true according to A Teen’s Guide to Going Vegetarian?
【正确答案】 B
【答案解析】[设题点] 观点总结处
[解析] 事实细节题。由A Teen’s Guide to Going Vegetarian将答案锁定在第二段第五句话。[B]同义转述了文中的protein is found in almost every food,故为答案。[A]其实是critics的观点,protein是文中nutrients的下义词;[C]与第二段第六句话相矛盾;[D]是1988年的一项研究所发现的内容;此三项皆予以排除。
单选题 In the third paragraph, the author implies that
【正确答案】 C
【答案解析】[设题点] 例证处、数字处
[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。

【正确答案】 D
【答案解析】[设题点] 例证处
[解析] 推理判断题。文章第四段举了家禽和猪的例子,谈到:由于密集饲养,家禽被削掉了嘴尖,而猪被拔了牙齿,切了尾巴。浏览选项:首先排除[A],因为[A]“饲养家畜不道德”不合逻辑;[B]“吃动物不道德”是许多人成为素食者的原因;[C]表意肤浅;只有[D]“成为素食者对动物的健康有好处”表意深刻且概括了作者举例子的目的。故[D]为答案。
单选题 Which of the following would be the best title for the text?
【正确答案】 A
【答案解析】[设题点] 首段,尾段
[解析] 主旨大意题。这类题目的解题关键在于寻找主题句,一般出现在文章的第一段和最后一段。遇到这种题型时,首先要认真阅读文章第一段的起始句和最后一句,再到最后一段的第一句或最后一句去找出与之相呼应的句子,以此就能轻易地找出全文的主题句或中心大意,然后再确定文章的题目。本文章中,第一段最后一句是主题句,最后一段最后一句照应主题句,两句都讲到了少吃肉类的好处,因此[A]为答案。
