Many __________ mental issues of teenagers are blamed on a lack of communication with their parents.

Don't Let Depression Ruin a Good Thing

Feeling down? Got the blues? You're not alone. Everyone gets. sad (yes, everyone you've ever met). Some people have sad feelings just once in a while, and others may have sad feelings pretty often. More than half of teenagers go through a sad period at least once a month and plenty of younger kids do, too.

When you're in a sad mood, it may feel like it will last forever, but usually feelings of sadness don't last very long a few hours, or maybe a day or two. A deeper, more intense kind of sadness that lasts a lot longer is called depression. Each year millions of people are estimated to suffer from depression, a condition so widespread that it has been dubbed "the common cold of mental illness. "

Symptoms of Depression

Depression is associated with many symptoms and not everyone has the same ones. Some people have many symptoms, while others may only have a few. The symptoms below may signal that you or someone you love may be depressed:

Appearance—sad face, slow movements, absent-minded look

Unhappy feelings—feeling sad, hopeless, discouraged, or listless

Negative thoughts—"I'm a failure," "I'm no good," "No one cares about me. "

Reduced activity—"I just sit around and mope," "Doing anything is just too much of an effort."

Reduced concentration.

People problems—"I don't want anybody to see me," "I feel so lonely."

Guilt and low self-esteem—"It's all my fault," "I should be punished."

Physical problems—Sleeping problems, weight loss or gain, decreased sexual interest, or headaches.

Suicidal thoughts or wishes—"I'd be better off dead," "I wonder if it hurts to die."

Causes of Depression

The exact cause of depression remains unclear. The most probable explanation is that it is an imbalance in neurotransmitters (神经传递素) in the brain. But what triggers it in the first place?

First, genetic factors. There is growing interest in genetic approaches t6 understanding a variety of diseases and depression is no exception. Some people certainly seem to be more vulnerable to depression than others and there is growing evidence that some genes could make individuals susceptible to the disease. Some studies have shown that people who have relatives with depression have a one in four chance of developing it themselves, compared with only one in fourteen for the general population.

Secondly, external triggers. In most cases just having these genes is probably not enough to cause depression on its own. Depression can be triggered by a number of factors such as unemployment, bereavement (丧亡), social isolation or even a severe physical illness.

Victims of Depression

Anyone may suffer from depression, regardless of age, gender, race and belief. It is "normal" for certain people to feel depressed-such as women, older people, employees with work-related stress, or people with chronic illness.

Women are more than twice as' likely as men to experience depression. Although the reasons for this difference are not known, research suggests that biological differences in women such as hormonal(荷尔蒙) changes and genetics-may contribute to depression. Additionally, social reasons, such as greater stresses from work and family responsibilities, and even the increased rates of sexual abuse and poverty among women, may lead to higher rates of clinical depression.

Depression affects employees at all levels of the corporate ladder. One in every 20 employees experiences the illness. An estimated 200 million workdays are lost each year due to employee depression. Depression tends to affect people in their prime working years and if left untreated may last a lifetime.

听力原文： Experts from more than 100 countries are gathering in the Swedish capital Stockholm to discuss global water and sanitation issues, at the start of World Water Week today. The organizers have emphasized the importance of addressing the problem of water and sanitation in eliminating poverty, disease and gender inequality, as well as curbing environmental damage. Barbara Miller reports:

The statistics of the worldwide water crisis are staggering. 1 in 5 people lack access to a safe water supply. 2 in 5 don't have basic sanitation and a child dies every 30 seconds, as a result of a lack of clean drinking water and sanitation. For a long time what are known as hard approaches to solving these problems were predominantly applied, the construction for example of large-scale infrastructure such as dams and irrigation systems. This year the conference hosts at the Stockholm International Water Institute want to focus attention on ensuring these methods are balanced with soft approaches such as marketing campaigns to promote hand washing. The conference will also consider the impact of corruption and development, how climate change affects world water supplies, and the opportunities for water sharing in the Middle East, which is facing severe water scarcity.

The conference addresses the following issues EXCEPT ______.

A．poverty

B．gender inequality

C．environmental protection

D．world peace

More efforts are being made toward environmentally safe work places. An environmental policy research organization has done that in Washington, D.C. The World Resources Institute re-designed its office to make it safer for people and the environment. This newly-designed office is called a "green" office.

2. The newly designed office was made with environmentally safe building materials instead of building products that are harmful to the environment. For example, the floor of the office is made of bark(树皮)from a cork tree. The bark of a cork tree will renew itself so the tree does not die. The cork floor also feels good to stand on.

3. The floor in another part of the office is made of bamboo(竹子). Bamboo is a fast-growing grass that quickly replaces itself. Other areas of the floor are covered with carpeting. However, unlike many offices, the carpet was made without harmful chemicals.

4. Storage areas in the office are made from the crushed shells of sunflower seeds. The office doors are made from pressed wheat straw. Wheat straw is an agriculture waste product that would normally be burned. That process adds chemicals to the atmosphere.

5. World Resources Institute officials also chose lighting and other electrical equipment that use less energy. And, they improved their communication systems. New video communication equipment lets workers see and talk to people in other cities. The new equipment was added to reduce the amount of travel by office workers. That reduces the amount of harmful gases that are released into the atmosphere by cars or planes.

6. The organization's officials also announced a plan that would reduce harmful carbon dioxide gases from their office by the year 2005.

7. World Resources Institute officials say the cost of building a "green" office is similar to that of a traditional office. They say building more "green" offices could lead to a healthier environment. They say a healthy environment and a strong economy can exist together. The organization says it is creating a work environment that is better for people.

A. A plan to reduce harmful gases from offices

B. A "green" office safer for people

C. The decoration of the green office

D. The materials of the green office

E. More things to do for a better work environment

F. The cost of the green office

Last year， researchers published new findings from the Women"s Health Initiative， a long-term study of more than 160000midlife women. The data showed that multivitamin-takers are no（26）than those who don"t take the pills， at least when it comes to the big diseases——cancer， heart disease， and（27） "Even women with poor diets weren"t helped by taking amultivitamin，" says the study author Marian Neuhouser， PhD， in the cancer（28）program at the Fred Hutchinson CancerResearch Center， in Seattle. Vitamin（29）came into fashion in the early 1900s， when it was difficult or impossible for most people to get a wide variety of fresh fruits and vegetables. Back then， vitamin-deficiency diseases weren"t unheard-of: the bowed legs and（30）ribs caused by a severe shortage of vitamin D， or the skin problems and mental confusion caused by a lack of vitamin B， But these days， you"re（31）unlikely to be seriously deficient if you eat an average diet， if only because many packaged foods are vitamin-enriched. Sure， most of us could do with a couple more daily（32）of produce， but a multivitamin doesn"t do a good job at（33）those. "Multivitamins have maybe two dozen（34）but plans，s have hundreds of other useful compounds，"Neuhouser says. "If you just take a multivitamin， you"re missing lots of compounds that may be providing benefits. " There is onegroup that probably ought to keep taking a multivitamin: women of reproductive age.

We should also know that "greed" has little to do with the environmental crisis. The two main causes are population pressures, especially the pressures of large metropolitan populations, and the desire—a highly commendable(praiseworthy)one—to bring a decent living at the lowest possible cost to the largest possible number of people.

The environmental crisis is the result of success—success in cutting down the mortality (死亡率)of infants (which has given us the population explosion), success in raising farm output sufficiently to prevent mass famine (which has given us contaminati9n by pesticides and chemical fertilizers), success in getting people out of the houses of the 19th-century city and into the teenager and privacy of the single-family home in the suburbs(which has given us urban sprawl and traffic jams). The environmental crisis, in other words, is largely the result of doing too much of the right sort of thing.

To overcome the problems that success always creates, one must build on it. But where to start? cleaning up the environment requires determined, sustained effort with clear targets and deadlines. It requires, above all, concentration of effort UP to now we have tried to do a little bit of everything—when what eve ought to do first is draw up a list of priorities.

This passage assumed the desirability of______.

A．1iving in comfortable family lifestyles

B．setting disputes peacefully

C．combining cancer and heart diseases with energetic research
