Vegetarianism A strict vegetarian is a person who never in his life eats anything derived from animals. The main objection to vegetarianism on a long-term basis is the difficulty to getting enough protein, the body building elements in food. If you have ever been without meat or animal foods for some days of weeks(say, religious reasons) you will have noticed that you tend to get physically rather weak. You are glad when the fast is over and you get your reward of a succulent meat meal. Proteins are built up from approximately twenty food elements called "amino-acids", which are found more abundantly in animal protein than in vegetable protein. This means you have to eat a great deal more vegetable than animal food in order to get enough of these amino-acids. A great of the vegetable food goes to waste in this process and from the physiological point of view there is not much to be said in favor of life-long vegetarianism. The economic side of the question, though, must be considered. Vegetable food is much cheaper than animal food. However, since only a small proportion of the vegetable protein is useful for body-building purposes, a consistent vegetarian, if he is to gain the necessary 70 grams of protein a day, has to consume a greater bulk of food than his digestive organs can comfortably deal with. In fairness, though, it must be pointed out that vegetarians claim they need far less than 70 grams of protein a day. Whether or not vegetarianism should be advocated for adults, it is definitely unsatisfactory for growing children, who need more protein than they can get from vegetable source’’s. A lacto-vegetarian diet, which includes milk and milk products such as cheese, can, however, be satisfactory as long as enough milk and milk products are consumed. Meat and cheese are the best sources of usable digestible and next come milk, fish and eggs. Slow and careful cooking of meat makes it more digestible and assists in the breaking down of the protein content by the body. When cooking vegetables, however, the vitamins, and in particular the water-solube vitamin C, should be lost through overcooking. Which of the following is best reflected the author’s attitude?

A:Vegetarianism is not good for one’s health. B:Vegetarianism should be advocated for adults. C:One should have a well-balanced diet containing elements of all foods. D:A lacto-vegetarian diet is the best as it provides adequate nutrition.

Today vegetarianism is trendy -25 percent of adolescents even think it’s "cool". The success of vegetarian cosmetics and vegetarian foods like veggie dogs and turkey is a testament to the diet’s popularity. Groups that promote vegetarianism and animal rights, like the Humane Society of the United States (HSUS) and People for the Ethical Treatment of Animals (PETA), have tremendous lobbying (游说) power with major companies. But vegetarianism hasn’t always been so generally accepted, nor has it always been linked with the animal - rights movement.
In 17th - and 18th - century Europe, some Protestant groups embraced vegetarianism as a moral directive - a way to be sinless. By the 19th century, European and North American vegetarianism had become a fringe (外围的) health movement. Adherents promoted the dietary benefits of vegetarianism -even coupling it with temperance (戒酒) and anti - tobacco movements. Modem, organized vegetarianism began with the formation of the Vegetarian Society in 1847 by the Bible Christian Sect of England. Within a year, the Society had 478 members.
It wasn’t until the mid 20th century that vegetarianism partnered with animal rights movement. America’s most notorious animal rights organization, PETA, vigorously protests against all meat, animal products and animal testing. It is best known for its bold ad campaigns. The HSUS takes a less strict approach. It accepts that people will eat meat and focus instead on reducing meat consumption, replacing animal products and improving farming techniques. Both PETA and the HSUS, however, are powerful political machines: They hold stock in companies like Tyson, Wal - Mart, McDonald’s and Smithfield’s. The modem vegetarian movement is getting ever more powerful.
Which of the following is not true according to the first paragraph

A:Vegetarianism is trendy and many youngsters applaud it. B:It has always been generally accepted and linked with the animal -right movement. C:Popularity of the diet is reflected by the success of vegetarian cosmetics and vegetarian foods. D:Groups that promote vegetarianism and animal rights are influential to some big companies.

Vegetarians choose their diet for many reasons. Some are health - conscious, some believe animal agriculture hurts the environment and others have moral or religious objections to meat.
Vegetarianism has become a popular health diet. Vegetarian favorites like fruit, vegetables, whole grains, and legumes (豆科植物) are low in fat and cholesterol (胆固醇) and rich in fiber, vitamins C and E. The American Dietetic Association even reports that vegetarians have lower blood pressure, cholesterol and body mass indexes than non - vegetarians. Of course, no diet is automatically healthy. Vegetarians must make sure they take in enough protein, calcium and vitamin B12 without overindulging in fatty, high -calorie foods like cheese.
Many vegetarians are as concemed with the Earth’ s well - being as they are with their own. Some vegetarians choose the diet for environmental reasons because they believe traditional agriculture has less of an ecological impact than animal agriculture.
People usually try not to think about where their meat comes from. It can be unpleasant toimagine your hamburger as a wide - eyed cow in the pasture, let alone as an unhealthy animal in acramped (狭小的) factory farm. But for many vegetarians, disassociation or denial is impossible. They often feel morally unable to eat animals slaughtered for their meat. Vegans take their ethical objections a step further and refuse to eat dairy or eggs from animals that they believe have led unnaturally short and unhappy lives.
Some of vegetarianism’ s ethical concerns have spread to the mainstream. Even steadfast (忠诚的，忠实的) meat - eaters often like the idea of free - range (活动范围不受限制的) chicken or cage -free eggs- animal husbandry (饲养业) techniques that promise a more compassionate (表示怜悯同情的) altemative to traditional factory farming.
Vegetarians have long chosen the diet for ethical reasons. Although the first practitioners only temporarily avoided meat for purification, the first regular vegetarians began the diet after philosophical awakenings in the Eastern Mediterranean region and India.
The philosopher Pythagoras of Samos (c. 530 BC) taught vegetarianism to his followers. Pythagoras believed that because we are related to animals, we should treat them with kindness. Many other famous philosophers agreed--Plato, Epicurus and Plutarch condemned animal sacrifice and avoided eating meat.
In India, the Buddhist religions teach that humans should not kill living creatures for food. Although Buddhism later declined in India, vegetarianism remained and spread among people Many upper classes and some lower classes adopted the virtue of harmlessness, which forbade hurting living things.
In paragraph seven, the author cites several philosophers to

A:prove that many philosophers are/have been vegetarians. B:show how philosophy contributed to the development of vegetarianism. C:compare how they differed in the philosophical theories. D:tell the reader that vegetarianism has had a very long history.
