1. 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 of getting enough protein-the body-building element in food. If you have ever been without meat or other animal foods for some days or weeks (say, for religious reasons), you will have noticed that you tend to get physically rather weak. You are glad when the fast（斋戒） is over and you get your reward of a succulent（汁多味美的）meat meal. 2. Proteins are built up from approximately twenty food elements called \amino-acids\ (氨基酸), 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 deal 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. 3. 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 amount 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. 4. 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 sources. A lacto-vegetarian (乳蛋素食者) 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 useable animal protein and next come milk, fish and eggs.【缺少答案，请补充】

1. There are two basic ways to see growth: one as a product, the other as a process. People have generally viewed personal growth as an external result or product that can easily be identified and measured. The worker who gets a promotion, the student whose grades improve, the foreigner who learns a new language--all these are examples of people who have measurable results to show for their efforts. 2. By contrast, the process of personal growth is much more difficult to determine, since by definition it is a journey and not the specific signposts or landmarks along the way. The process is not the road itself, but rather the attitudes and feelings people have, their caution (小心) or courage, as they encounter new experiences and unexpected obstacles. In this process, the journey never really ends; there are always new ways to experience the world, new ideas to try, new challenges to accept. 3. In order to grow, to travel new roads, people need to have a willingness to take risks, to confront the unknown, and to accept the possibility that they may \fail\ at first. How we see ourselves as we try a new way of being is essential to our ability to grow. Do we perceive ourselves as quick and curious? If so, then we tend to take more chances and to be more open to unfamiliar experiences. Do we think we're shy and indecisive? Then our sense of timidity (胆小) can cause us to hesitate, to move slowly, and not to take a step until we know the ground is safe.Do we think we're slow to adapt to change or that we're not smart enough to cope with a new challenge? Then we are likely to take a more passive role or not try at all. 4. These feelings of insecurity and self-doubt are both unavoidable and necessary if we are to change and grow. If we do not confront and overcome these internal fears and doubts, if we protect ourselves too much, then we cease to grow. We became trapped inside a shell of our own making.【缺少答案，请补充】

1. Doctors, lawyers and health authorities say the sale of organs by poor donors (捐赠者) is a growing phenomenon. Because it is possible to live with just one kidney and because demand for the organs is so high, kidneys are among the most popular organs for commercial deal. People have sold their own blood for years. 2. The new British law makes it a criminal offense to give or receive money for supplying organs of either a living or dead person. It also prohibits acting as a broker (中间人) in such an arrangement, advertising for organs for payment or transplanting an organ from a live donor not closely related to the recipient (接受者). 3. A new computerized nationwide registry, which records all transplants from both live donors and dead bodies, will be used to help enforce the law. At least 20 other countries, including the United States, Canada and most of Western Europe, already have laws or policies prohibiting the sale of human organs. 4. Britain has had a transplant law since the 1961 Human Tissue Act, which considered it immoral for a practitioner (开业者) to traffic in human organs. But the new law is believed to be the world's first legislation aimed exclusively at the commercial organ transactions. 5. The British law applies only to transplants performed in the nation's private hospitals and not to those overseas by the government-supported National Health Service, which provides free medical care for British citizens. The service, which has not used paid donors, gets first pick of all kidneys available for transplant in the nation. At present, about 1,600 transplants are performed each year, with a waiting list of about 3,600 patients.【缺少答案，请补充】
