Researchers study television to understand its effects on viewers and to measure its effectiveness in selling products. Much of the research on TV audiences is market research, paid for by companies with something to sell. Let me repeat; research on television is supported largely by advertisers.

The television industry depends on advertising money to run, and this relationship influences what television offers viewers. Advertisers aim to reach mass audiences and particular social groups. In turn, the television tries to meet the needs of advertisers, because pleasing the advertisers is nearly as important as pleasing the public. This means advertisers have a lot of control over what programs are made and when they are shown.

Television is the most effective marketing tool ever created. Many advertisement apply basic psychology（心理学）by sort of turning to our insecurities and desires. Ads convince us that the things we once thought were luxuries（奢侈）are now necessities. Television is highly programed as well. Using expert market research, programmers and advertisers sort to paint a picture of life centered on material possessions. This kind of life may look attractive and desirable, but it’s all at the expense of personal relationships.

As you probably can tell, I prefer to agree with critics（评论家）of the media. Advertising does create false needs, and products we really need don’t require advertising. Television advances consumerism（消费至上）. It shows us things, things, and more things. It encourages greed and envy. Television helps create a wasteful society, where things are thrown out long before they are worn out.

1.What is the main idea of the passage?

A．Television research is an interesting field.

B．Advertising is effective in selling products

C．Television helps develop a culture of consumerism

D．The television industry should be better managed

2.According to the passage, researchers study television to ________.

A．learn about the types of programs

B．understand the culture of the society

C．decide which programs to export

D．measure how much it help to sell products

3.The writer uses the underlined sentences in Paragraph 3 to________.

A．argue that television images of life lack depth and meaning

B．warn readers not to spend more money than they can afford

C．show that television programs can advance personal growth

D．suggest that readers watch only high-quality programs

4.What is the writer’s opinion of television?

A．Television is the best way to advertise products and services.

B．Television mostly has had a side effect on viewers

C．People have a wrong opinion of television

D．It is the duty of television to help create a rich society

When it comes to the prevention of heart disease, women need to pay attention to their own special risks. And so do men. Surprisingly, even children and teens need to be aware- or at least the parents who want to keep them safe do. Thankfully, scientists have also made great leaps in figuring out the specific prevention strategies that work best for all. So now, knowledge is your best protection.

What Men Need to Know

According to the American Heart Association (AHA), at least half of the people who die suddenly from heart disease each year had no clue they were sick. Some think that half of all heart attacks strike out of the blue. Not true, insists Jennifer Mieres, a spokeswoman for the AHA. A 2004 study found that at least 90 percent of first heart attacks are caused by well-known problems like high cholesterol(胆固醇) or diabetes. “If you look closely,” says she, “you’ll almost always find a risk factor that was undiscovered, ignored, or not adequately treated.”

Lifestyle changes like adopting a healthy diet, getting out for regular exercise, avoiding tobacco, losing weight are the first line of defense.

What Women Need to Know

There are some special considerations for the women who are  healthy and want to make sure they stay that way. First, they shouldn't smoke-no one should, but the habit is even harder on women's heart than it is on men's.

Women who find that they are at risk should talk to their doctor about taking a statin(他汀,药物名). Indeed, statins reduce the risk of heart disease, but there has been not enough evidence that they help high-risk women and it can't guarantee the long-term safety. So it's worth noting that a healthy diet and exercise also reduce cholesterol.

What Parents Need to Know

Last year, a study showed that overweight children and teens have arteries(动脉)that look like those of an average 45-year-old. New guidelines say these children should get a cholesterol test by age ten -- and even urge doctors to consider statins for those most at risk if nothing else works. The recommendations caused oppositions. Lifestyle changes such as diet and exercise are the best strategy, says Dr. Greer, a professor at the University of Wisconsin School of Medicine. Statins should be considered only for kids in danger.

A decade-long study, also the first major research into air pollution and disease has shown that living near a main road increases the risk of dementia(痴呆). The study of 6.6 million people found that one in 10 dementia deaths in people living within 50 metres of a busy road was due to waste gas and noise.

Air pollution is already known to contribute to the deaths of around 40,000 people in Britain each year by worsening breathing and heart conditions, while previous research showed emissions (排放物) can cause brain shrinkage. But the new study by Canadian public health scientists is the first to find a link between living close to heavy traffic and the increasing of dementia, a discovery described as "believable" and "impressive" by British experts.

Dr Hong Chen said. "Our study suggests that busy roads could be a source of environmental stressors that could give rise to the onset of dementia. Population growth and urbanization has placed many people close to heavy traffic, and with widespread exposure to heavy traffic and growing rates of dementia, even a modest effect from near-road exposure could cause a large public health burden.  More research to understanding this link is needed, particularly into the effects of different aspects of traffic, such as air pollutants and noise."

In the new study, the team tracked all adults aged between 20 and 85 living in Ontario for more than a decade from 2001 to 2012. They used postcodes to determine how close people lived to a main road and analyzed medical records to see if they went on to develop dementia, Parkinson's disease or multiple sclerosis(多发性硬化).

While there was no correlation between living near a road and Parkinson's disease or multiple sclerosis, dementia risk reduced as people lived further from a main road, with a 7 percent higher risk in developing dementia among those living within 50 metres; a 4 percent higher risk at 50-100 metres and a 2 percent higher risk at 101-200 metres. After 200 metres there was no increase. Researchers believe that noise of traffic may also play a role in the raised risk as well as other urban pollution, which is often present near busy roads.

1.What can we know about Canadian's new study?

A. British experts think highly of it.

B. It brings benefits to dementia patients.

C. It shows that air production is very serious.

D. It shows that air pollution can cause brain shrinkage.

2.What Dr Hong Chen said showed that______.

A. people are diagnosed with dementia mainly due to air pollution

B. widespread exposure to traffic will reduce the risk of having dementia

C. the link between living near roads and having dementia was not obvious

D. busy roads could be a source of environmental stressors that caused dementia to increase

3.What does the underlined the word ‘correlation’ mean?

A. Change.　　 B. Improvement.

C. Association.　　 D. Secret

4.What can be inferred from the last paragraph?

A. Living near a main road adds to the risk of noise.

B. Living beyond 300 metres of a main road is safe for people.

C. Living within 200 metres of a main road has a lower risk of having dementia.

D. The further people live away from heavy traffic, the smaller the risk of having dementia.

When we hear of dangerous diseases, cancer and heart disease are often what first come

to mind. Recently, a virus called Ebola has reappeared in Guinea, killing 62 people so far. It leads to high fever, bleeding and so on. Ebola can kill 90% of those infected (感染), especially in underdeveloped societies like those in Africa.

Ebola is named after the Ebola River, where it was first discovered in 1976. There are five different types of the Ebola virus, each named after where they first happened: Sudan, Ivory Coast, Reston, Bundibugyo, and Zaire. The deadliest of the five, Zaire, was responsible for the 2012 outbreak, and is believed to be attacking Guinea.

Ebola is naturally found in fruit bats, which pass on the virus to other animals by biting or sucking on their blood. Humans who are suffering from the Ebola infection might have touched the bodily fluids (体液) of the infected animals. Once infected, a human becomes a carrier of the deadly virus.

Since we live in an interconnected world, where the situation in one country can affect us all, the effects of Ebola are huge: damaging trade relations, affecting foreign visitors, and weakening entire countries. Already the Guinea virus is spreading fast with a few cases spotted in Conakry—the capital city of Guinea, far away from the origin of the virus. It is feared that the disease may have already reached neighboring Liberia and Sierra Leone, too.

Unfortunately, there are no disease-specific treatments for Ebola. Healthcare workers only supply the infected people with water to keep them in good condition. Since there have been many cases of nurses catching the disease from patients, they are forced to wear strict protective clothes, and in some cases, not even allowed to get close to the infected. The fact that there is no cure for the Ebola virus is what makes the outbreak a challenging one to control.

1.From the text we know that ________.

A. Ebola is naturally found in fruit

B. Ebola is a highly infectious virus

C. Ebola is a newly discovered disease

D. Ebola is recently controlled in Guinea

2.What is Paragraph 4 mainly about?

A. The causes of Ebola.　　 B. The origin of Ebola.

C. The treatment for Ebola.　　 D. The influences of Ebola.

3.In Ebola infected areas, healthcare workers _______.

A. face the danger of catching virus

B. take measures to protect the nurses

C. give water and medicine to the patients

D. do whatever they can to save the infected

4.The text probably comes from ________.

A. an English newspaper　　 B. a tourist guide

C. a safety brochure　　 D. a medical report

When a cat is frightened, its heart starts beating faster, its muscles get tense, and there are changes in the chemicals in its bloodstream. If the danger continues, it will defend itself, or it will run away as fast as possible.

Something like this also happens to people. When we are excited, angry, scared or aroused(冲动) by others' emotions, our bodies go through many physical changes, all of which make us more alert（警惕的） and ready to react. We also get ready to defend ourselves or run. Human beings, however, have a problem that animals never face. If we give way to our feelings and let them take over, we can get into trouble. Have you ever said something in anger —— or hit somebody —— and regretted it later? Have you ever shouted at a teacher, told somebody you were lonely, or said you were in love, and then wished later you had kept your mouth shut? It isn't always wise to express your feelings freely.

Does this mean that it's smarter always to hide our feelings? No! If you keep your feelings of anger, sadness, and bitterness hidden away or bottled up(掩饰) inside, your body stays tense. Physical illnesses can develop, and you can feel disturbed badly inside. It can actually be bad for your health.

You can try to treat emotions as if they were bananas in the cupboard. You can hide them and you can pretend they don't exist, but they'll still be around. And at last you'll have to deal with them, just like those bananas.

C. people's physical reactions are like those of animals in a way

B. we should put some bananas in the cupboard when we're angry or scared

C. feelings will gradually disappear when we hold them in

D. we should neither express our feelings freely nor hide the bad feelings inside
