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.

B. About 10 million people will die from smoking each year by 2020.

The belief that new technologies are causing the death of work is the idea that never goes away. Despite evidence to the contrary, we still view technological change today as being more rapid and dramatic in its consequences for work than ever before. But this is nothing new. People have always viewed the technological changes that take place during their lives the most dramatic and dangerous that ever happened in history.

In the 1930s, the British economist（经济学家）John Maynard Keynes predicted the widespread use of electricity would produce a world where people spend most of their time doing nothing. In the United States during the 1960s, the government repeatedly investigates fears that automatic machines would permanently reduce the amount of work available, In 1988, one Australian historian claimed that at least a quarter of the workforce would be without jobs within 10 years because of computers.

Of course, none of these disasters came to pass in the United Kingdom, the United States and Australia, or anywhere else.

Yet today, we are seeing the return of these predictions, with some experts claiming the world of work once more undergoing radical and unprecedented change. They argue that robots and other workplace technologies are causing a reduction in the total amount of work available, or are bringing a more rapid pace substitution of machines for humans has been seen previously.

But there is a little evidence to support such beliefs, Statistics show that the percentage of people in work, the number of hours they work, and how frequently they change jobs have remained remarkably constant over the past 20 years.

This stability should not come as a surprise, There are good reasons why we should not expect new technologies to cause the death of work. New technologies always cause job losses, but that is only part of the story. What also needs to be understood is how they increase the amount of work available.

One way this happens is through the increases in incomes that accompany the use of new technologies. With the introduction of these technologies, good and services can be produced faster, which results in higher real incomes for workers. Higher incomes then increase demand for other products and consequently more workers are needed to make them. Additionally, while new technologies are likely to substitute for some types of workers, they will also increase demand for other types of workers, especially those with higher level skills and expertise.

So, the end of work is no closer today than at any time in the past. But there is still a need to keep disproving the prediction, to reduce people’s fears.

1.What is the function of the second paragraph?

A. To explain the importance of developing new technology.

B. To give historical examples of unnecessary fear about new technology.

C. To argue that technological dangers are becoming more serious.

D. To show how technology affected employment in the past.

2.How can employment statistics over the past 20 years best be described?

A. Confusing　　 B. Reliable

C. Stable　　 D. Variable

3.According to paragraph 7, why does demand for products often increase after new technology is introduced?

A. Productivity improvements help raise workers’ salaries.

B. There is more demand for new skills in the economy.

C. There are more goods for people to choose from.

D. Higher quality goods at lower prices encourage consumption.

4.What is the author's opinion about the introduction of new technology?

A. It does not have an effect on most people’s jobs.

B. Its danger to peoples employment possibilities is overstated.

C. It usually leads to a significant increase in employment.

D. Its benefits are usually not worth the introduction.

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.

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.

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.

1.What physical effects does stress result in?

A.Overreacting to little problems.

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.

1. According to the passage, which of the following ranks NO. 1 among the causes of disability?

A. Cancer. B. Depression.

C. Back pain D. Heart disease.

2.What can we learn from the first paragraph?

A. Depression has been treated as a global public health priority.

B. PLOS Medicine is a website dealing with medical problems.

C. The study only analyzes depression all over the world.

D. Most patients with depression haven’t been treated.

3.Who is Alize Ferrari?

A. She is a doctor working in a hospital.

B. She is a professor at a university leading the study.

C. She is an official from the government.

D. She is a common teacher taking part in the study.

4.Which of the following is TRUE according to Paragraph 4?

A. There is a common standard of recognizing disability worldwide.

B. Most reasons for disability are similar.

C. Mental health has raised much attention among people.

D. How to find patients suffering from depression is not easy.

5.Why did the WHO start a global mental health action plan?

A. To make policy-makers of all countries pay attention to the problem of depression.

B. To help patients become healthier.

C. To raise the status of doctors in the world.

D. To help build more colleges that study mental health.
