Suicide has been a cause of concern in most societies for a long time. The classical Greeks, for example, required people who wanted to kill themselves to get permission from the senate. While this law is not without humor by today's standards, it clearly shows an awareness of the problem in times gone by.
In today's society, is much more prevalent than we want to admit. Why do people try to take their own lives?
The motives for can be categorized into areas such as a failure, wrath(暴怒), the needfor attention, stress, and so on. However, the qualities of a person who wants to take his own life change from person to person, making it difficult to depict(描写)the typical victim. To make the problem even more confusing, people will often camouflage(掩盖)their true feelings, thus causing their friends to disregard problems that should be viewed as serious.
In theUnited States, a network of centers has been created to attempt to prevent s.People who are bitter, worded, or depressed are encouraged to contact workers at these centers. These workers, often trained volunteers, offer benevolent advice to the callers, trying to help the callers to see that as a solutions to problems is an illusion. The accomplishments of these centers, insofar(到这个程度)as their effectiveness to reduce is concerned, are minimal However, they have helped a lot of people with a wide variety of problems. So, in the somewhat amorphous(难以名状的)area of man helping his fellow man, they are certainly a success.

细节题。C的含义是说人们在努力地帮助那些想的人，在某种程度上他们已经取得了一定的胜利。文章的一句就是这个意思?
Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need. It has been demonstrated that rats will, when given a choice over a period of time, prefer water with vitamins to water without vitamins even though there is no difference in taste or smell between the two water bottles. When a fragrant flavor was added to the vitamin enriched fluid, the rats did seem to develop a taste for it and kept drinking it, even after the vitamins were switched to the clear water. In time, however, they broke the habit and went back to where the necessary vitamins were.
In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria feeding arrangement, with a wide selection of baby food before them. They were given whatever food they pointed to or appeared interested in. We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet.
So, in selecting food, rats and babies do seem to know and act on what's best for them.Apparently, there is a kind of "body wisdom", which hmnans soon lose.Most of us do not eat as wisely as we could.
Many of our food preferences are culturally determined and influenced by long-established habits. Some people eat fox, dog and blackbirds, while we eat cows and pigs. So what people eat and how much they eat seem to be greatly influenced by what is going on around them.

A.encourage rats to drink vitamin-enriched water
B.find out rats preference in flavor
C.test whether rats know which drink is good for them

参考答案：C
细节题。答案在文章一段"It has been demonstrated that rats will, when given a choice over a period of time, prefer water with vitamins to water without vitamins even though there is no difference in taste or smell between the two water bottles."
7.The expression "the habit"( Line 6, Paragraph 1) refers to drinking water which ( ).
A.has no smell
B.is tasteless
C.has vitamins
D.is flavored
参考答案：D
细节题。一段的谈到"When a fragrant flavor was added to the vitamin-enriched fluid.the rats did seem to develop a taste for it and kept drinking it…"所以句子中的habit实际上指的是老鼠喜欢喝有香味的水。所以D是正确答案。

B.adults usually cannot resist the temptation of various delicious foods
C.adults' eating habits are closely related to the social and cultural customs
D.adults have more choices of food than babies in eating patterns
参考答案：C
细节题。由文章第二段的一句"Babies managed to select well-balanced diet."和文章的第三段中："Many of our food preferences are culturally determined and influenced by lon established habits."可以看出成年人和婴儿的饮食习惯的不同点在于：成年人的饮食习惯和他们的社会和文化习俗有关。

细节题。根据上下文，我们可以知道，文章中并没有提到“大多数人都有合理的饮食;选择有营养的食物以及喜欢吃有香味的食品。”因此A、B、D都是错误的。根据文章的一句："What people eat and how much they eat seem to be greatly influenced by what is going on around them."可以断定“我们的饮食习惯受周围环境的影响。”C是正确答案。
10.As far as their eating habits are concerned, babies and rats are similar in that ( ).
A.both have the wisdom to choose a balanced diet
B.both prefer flavored food and drink
C.both have the same eating patterns
D.both develop a taste for the same kinds of flavors
