Depression is the second most common cause of disability worldwide after back pain, according to a review of research. The disease must be treated as a global public health priority (优先考虑的事), experts report in the journal PLOS Medicine. The study compared depression with more than 200 other diseases and injuries as a cause of disability. “Globally, only a small part of patients have opportunities to be treated,” the World Health Organization (WHO) says.

Depression was ranked at number two as a global cause of disability, but its effects varied in different countries and regions. For example, rates of major depression were highest in Afghanistan and lowest in Japan. In the UK, depression was ranked number three in terms of years when people lived with a disability.

Dr Alize Ferrari from the University of Queensland’s School of Population Health led the study.　　 “Depression is a big problem and we definitely need to pay more attention to it than we do now,” she told BBC News. “There’s still more work to be done in terms of awareness of the disease and also successful ways of treating it. The burden is different between countries, so the rate of depression tends to be higher in low and middle income countries and lower in high income countries.” Policy-makers have made an effort to bring depression to the forefront, but there is still a lot more work to be done.”

“There’re lots of confusions we know related to mental health,” Prof. Alize Ferrari explained. “What one person recognizes as disabling might be different to another person and might be different across countries as well, there are lots of cultural effects and explanations that are related to depression, which makes it more important to raise awareness of the size of the problem and also signs and how to find depression.”

The data—for the year 2010—follows similar studies in 1990 and 2000 looking at the global burden of depression. Commenting on the study, Dr Daniel Chisholm, a health economist at the department of mental health and substance abuse (药物滥用) at the WHO said depression was a very disabling condition.

“It's a big public health challenge and a big problem to be thought about but not enough is being done. Around the world only a tiny part of people get any sort of treatment or diagnosis.” Dr Daniel Chisholm said.

The WHO recently started a global mental health action plan to raise awareness of depression among policy-makers.

Stress is one of the most common causes of health problems in modern life. Too much stress results in physical, emotional, and mental health problems.

There are numerous physical effects of stress. Stress can affect the heart. It can increase the pulse rate, make the heart miss beats, and can cause high blood pressure. Stress can affect the respiratory (呼吸的) system. It can lead to asthma and cause a person to breathe too fast, resulting in a loss of important carbon dioxide. Stress can affect the stomach. It can cause stomachaches and problems of digesting food. These are only a few examples of the wide range of illnesses and symptoms resulting from stress.

Emotions are also easily affected by stress. People suffering from stress often feel anxious. They may have panic attacks and feel tired all the time. When people are under stress, they often overreact to little problems. For example, a normally gentle parent under a lot of stress at work may yell at a child for dropping a glass of juice. Stress can make people angry, moody, or nervous.

Long-term stress can lead to a variety of serious mental illnesses. Depression, an extreme feeling of sadness and hopelessness, can be the result of continued and increasing stress. Alcoholism and other addictions often develop as a result of overuse of alcohol or drugs to try to relieve（释放）stress. If stress is allowed to continue, then one’s mental health is put at risk.

It is obvious that stress is a serious problem. It attacks the body. It affects the emotions. Untreated, it may eventually result in mental illness. Stress has a great influence on the health, our feelings and our minds. So, reduce stress: stop the world and rest for a while.

Floods are second only to fire as the most common of all natural disasters.They occur almost everywhere in the world,resulting in widespread damage and even death.Consequently,scientists have long tried to perfect their ability to predict floods.So far,the best that scientists can do is to recognize the potential for flooding in certain conditions. There are a number of conditions,from deep snow on the ground to human error,which cause flooding.

When deep snow melts it creates a large amount of water.Although deep snow alone rarely causes floods,when it occurs together with heavy rain and sudden warmer weather it can lead to serious flooding.If there is a fast snow melt on top of frozen or very wet ground,flooding is more likely to occur than when the ground is not frozen.Frozen ground or ground that is very wet cannot absorb the additional water created by the melting snow.Melting snow also contributes to high water levels in rivers and streams.

Rivers that are covered in ice can also lead to flooding.When ice begins to melt,the surface of the ice cracks and breaks into large pieces.These pieces of ice move and float down the river,They can form a dam in the river,causing the water behind the dam to rise and flood the land upstream.If the dam breaks suddenly,then the large amount of water held behind the dam can flood the areas downstream too.

Broken ice dams are not the only dam problems that can cause flooding.When a large human-made dam breaks or fails to hold the water collected behind it,the results can be devastating.Dams contain such huge amounts of water behind them that when sudden breaks occur,the great force of the water is like a great tidal wave.The dam waters can travel tens of kilometres,cover the ground in metres of mud and litter,and drown and crush every thing and creature in their path.

Although scientists cannot always predict exactly when floods will occur,they do know a great deal about when floods are probably going to occur.Deep snow,ice-covered rivers,and weak dams are all strong conditions for potential flooding.

1.Which of the following shows the structure of the passage?

("P" stands for "Paragraph".)

A. 　　 B.

C. 　　 D.

2.Why does frozen ground probably contribute to flooding when deep snow melts?

A. It is likely to form an ice dam.

B. It is too hard for water to run off.

C. It cannot take in more water.

D. It makes the snow melt too quickly.

3.Which of the following words has the closest meaning to the underlined word "devastating" in Paragraph 4?

A. Positive.　　 B. Disappointing.

C. Impressive.　　 D. Damaging.

4.What is mainly talked about in the passage?

A. How floods come into being.　　 B. Where floods usually occur.

C. Why floods do huge damage.　　 D. How to prevent floods effectively.

An allergy is a strong reaction to a substance. Many things can cause allergies. The most common cause is pollen (花粉), which is usually produced by trees in the spring, grasses in the summer and weeds in the fall, as part of their reproductive process.

Other causes include organisms, chemicals, plants and dead skin particles from dogs and cats can also cause allergic reactions. So can insect stings and some food.

The most common kind of allergic reactions is itchy (痒的) , watery eyes and a blocked or watery nose. Allergies can also cause red, itchy skin. Some reactions can be life-threatening, for example, when breathing passages become blocked.

It is not always easy to avoid allergies. Drugs may offer an effective treatment. Another treatment used in some cases is called immunotherapy. A patient is injected with small amounts of the allergy-causing substance. The idea is that larger and larger amounts are given over time until the patient develops resistance in his body.

In the United States, experts estimate that up to 8% of young children have food allergies. Every year these allergies cause about 30,000 cases with severe reactions that require immediate treatment. It can result in breathing trouble and in some cases death. It is said that about 100 to 200 people will die. It is said that most of the reactions are caused by peanuts and tree nuts like walnuts.

People can also be allergic to medicines. The American Academy of Allergy, Asthma and Immunology says about 10％ of bad reactions to commonly used medicines are allergic. In other words, a person’s immune system overreacts and produces an allergic reaction. The most common reactions include skin rashes, itching, breathing problems and swelling in areas such as the face.

Heart disease is the leading cause of disability and death worldwide. 1. With that in mind, if you knew that you could help keep your heart healthy by eating just a little bit less every day- about six standard-size Oreos’ worth of calories-would you?

Researchers have found evidence that just a modest reduction in our daily caloric intake (摄入) could have protective benefits for our hearts. They drew on data from the Long term Effects of Reducing Intake of Energy (ERIE) study. According to the study, the experiment began with 218 participants, all of whom were normal weight or just slightly overweight and between the ages of 21 and 50. Researchers started 143 participants on a diet that reduced their caloric intake by 25%. 2.. In the end, 188 participants completed the study-117 with caloric restriction and 71 without. Over two years, people in the calorie-cutting group reduced their caloric intake by an average of about 12%.

3.. They lost about 16.5 pounds on average and saw improvements, including lowered cholesterol (胆固醇) and blood pressure, on all six primary factors associated with risks to heart health. “We expected there to be some improvement on cardiometabolic (心血管代谢) factors,” says William Kraus, the study’s lead author. “4..”

Though the weight loss was relatively impressive, it wasn’t responsible for a majority of the heart benefits. After conducting further analysis, researchers determined that caloric restriction can have health benefits above and beyond those normally associated with weight loss. “5..”

A. We need to do exercise to benefit heart.

B. The others were assigned to a normal diet.

C. It can hold back negative effects of aging.

D. But we didn’t expect the degree of improvement we saw.

E. About 2,200 people in the U.S. die per day due to heart problems.

F. The experiment was carried out by comparing two different groups.

G. This reduction in calories had significant effects on the participants who ate less.

One of the most popular and enduring myths about depression is that depressed people are sad all the time—and that by extension, people who are happy can’t be experiencing depression, even if they say they are. It is a mistaken version of depression. Depression doesn’t make you sad all the time.

When I’m having a depressive feeling, I’m not walking around in black clothes, and weeping. I go out with friends. I play jokes. I keep working, and have friendly chats with the people I work with. I read books. Above all, I experience moments of happiness. Yet I feel a strange conflicting pressure. On the one hand, I feel like I need to engage in a sort of sadness for people to understand that I really am depressed and that each day is a struggle for me. Because that way I will appear suitably sad, and thus, depressed—and then maybe people will recognize that I’m depressed and perhaps they’ll even offer support and assistance.

On the other hand, I feel an extreme pressure to perform just the opposite, because sad depressed people are boring and no fun, as I am continually reminded every time I speak openly about depression or express feelings of sadness and frustration. I’m caught in a trap where if I don’t perform sadness, I’m not really depressed, but if I express sadness at all to any degree, I’m annoying and boring and should stop being so self-centered. Depression can become your master, but you can slip out from under it occasionally. And many depressed people don’t actually spend it fainting dramatically on the couch and talking about how miserable they are.

1.Which of the following is TRUE according to the passage?

A. Sad people are always depressed.

B. Depressed people are sad all the time.

C. Happy people will never feel depressed.

D. Depressed people do not always feel sad.

2.When feeling depressed, the writer usually avoids ________.

A. expressing sad feelings straight

B. going out with friends and relatives

C. having friendly chats with colleagues

D. experiencing moments of happiness

3.What’s the writer’s attitude to being sad and depressed?

A. Positive.        B. Negative.        C. Indifferent.        D. Cold.

4.In the passage, the writer advises depressed people to ________.

A. speak openly about depression

B. hide the depression in the heart and never express it

C. be optimistic and become the master of depression

D. lie on the couch and talk about how depressed they are

Tobacco is the second major cause of death in the world. It is responsible for the death of one in ten adults worldwide (about 5 million deaths each year). If current smoking patterns continue, it will cause some 10 million deaths each year by 2020. Half the people that smoke today, that is about 650 million people, will eventually be killed by tobacco.

Tobacco is the fourth most common risk factor for disease worldwide. The economic costs of tobacco use are equally devastating (破坏性的). In addition to the high public health costs of treating tobacco-caused diseases, tobacco kills people at the height of their productivity, depriving (剥夺) families of breadwinners(养家糊口的人) and nations of a healthy workforce. Tobacco users are also less productive while they are alive due to increased sickness. A 1994 report estimated that the use of tobacco resulted in an annual global net loss of 200 thousand million US dollars, a third of this loss being in developing countries.

Tobacco and poverty are closely linked. Many studies have shown that in the poorest households in some low-income countries as much as 10% of total household expenditure is on tobacco. This means that these families have less money to spend on basic items such as food, education and health care. It contributes to a higher illiteracy rate, since money that could have been used for education is spent on tobacco instead.

Public speaking is a common cause of stress for everyone. The idea of standing in front of a large group with all eyes on you can make you feel fearful in almost all kinds of situation, for example giving a presentation in class, proposing a toast at dinner or making a work-related presentation. It seems to be a fear that’s impossible to overcome. If you have ever experienced this, you know while the anxiety may develop at the actual event, it is a feeling that begins much earlier than the actual day. There are many ways you can work on your confidence and prepare yourself for a public speaking event.

A consultant specializing (专门研究) in presentation skills can help you to overcome your sense of panic. Working with a consultant does not indicate that you have a major problem; it is only an approach to receiving guidance on relaxation strategies, such as deep breathing, which can help you deal with public speaking problems with ease.

Consultants can also help you work on your confidence. Confidence is extremely important in public speaking as it lets a speaker sound more convincing. Even well-established public speakers practice techniques such as meditation (沉思冥想) to calm themselves before a public appearance.

It’s well worth the time and effort to overcome the fear of public speaking, particularly if talks and presentations are part of your work description. Keep in mind that many of those around you are also struggling with this fear of public speaking. It will help you to become an able speaker if you can prepare beforehand. For example, you can put in time on planning your presentation in detail and practicing it many times in secret. As you get more and more familiar with your material, you’ll be able to fine-tune (微调) the details of your presentation and this will make you a confident speaker. Your speech will become excellent in terms of style and content.

Remember that the more you get into this pattern of feeling good about yourself, the stronger you will feel about approaching events when you have to make a speech. You can also work on physical details such as adjusting your tone (音调) before the presentation by doing some warm-up exercises.

In a word, believing in yourself and presenting yourself well can help you deeply impress your audience. And after a few speeches you’ll notice yourself overcoming the sense of panic that you now feel in public speaking situations.
