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.

In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception（感知） of the food in front of us.

Studies have shown, for instance, that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual clues, like plate size and lighting, have been shown to affect portion size and consumption.

A new study suggested that our short-term memory also may play a role in appetite. Several hours after a meal, people's hunger levels were predicted not by how much they’d eaten but rather by how much food they'd seen in front of them—in other words, how much they remembered eating.

This disparity (新旧研究的差异）suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal, says Jeffrey M. Brunstrom, a professor of experimental psychology at the University of Bristol.

"Hunger isn't controlled individually by the physical characteristics of a recent meal. We have identified an independent role for memory for that meal，" Brunstrom says. "This shows that the relationship between hunger and food intake is more complex than we thought."

These findings echo earlier research that suggests our perception of food can sometimes trick our body’s response to the food itself. In a 2011 study, for instance, people who drank the same 380-calorie milkshake on two separate occasions produced different levels of hunger-related hormones （荷尔蒙），depending on whether the shake’s label said it contained 620 or 140 calories. Moreover, the participants reported feeling more full when they thought they'd consumed a higher-calorie shake.

What does this mean for our eating habits? Although it hardly seems practical to trick ourselves into eating less, the new findings do highlight the benefits of focusing on our food and avoiding TV and multitasking while eating.

The so-called mindful-eating strategies can fight distractions and help us control our appetite, Brunstrom says.

1.What is said to be a factor affecting our appetite and food intake?

A. How we feel the food we eat.

B. When we eat our meals.

C. What element the food contains.

D. How fast we eat our meals.

2.What would happen at meal time if you remembered eating a lot in the previous meal?

A. You would probably be more particular about food.

B. You would not feel like eating the same food.

C. You would have a good appetite.

D. You would not feel so hungry.

3.What do we learn from the 2011 study?

A. Food labels may mislead consumers in their purchases.

B. Food labels may influence our body’s response to food.

C. Hunger levels depend on one's consumption of calories.

D. People tend to take in a lot more calories than necessary.

4.What does Brunstrom suggest we do to control our appetite?

A. Trick ourselves into eating less.

B. Choose food with fewer calories.

C. Concentrate on food while eating.

D. Pick dishes of the right size.

5.What is the main idea of the passage?

A. Eating distractions often affect our food digestion.

B. Psychological factors influence our hunger levels.

C. Our food intake is determined by our biological needs.

D. Good eating habits will contribute to our health.

A team of researchers in the UK has shown that children who were taken to the library more often and owned more books at two years old achieved higher scores in school tests when they began primary school. The research also showed that although social background has a noticeable effect on a child’s readiness for school, attending pre-school and having their parents teach them a wide range of activities have a positive effect---while extended exposure to television lowers their scores.

“One message coming through loud and clear is that how a child learns in his very early years is critical (至关重要的) for a smooth transition into the educational system,” said Professor James Law. “This is a very positive message, as it gets us away from the belief that a child’s educational future is pre-determined by standard measures of socio-economic disadvantage, such as income, housing, or the mother’s education.”

Data from the study shows that children from a positive communication environment had a better expressive vocabulary by their second birthday. These children went on to achieve higher scores in language, reading and maths tests when they entered school. In the early years, the communication environment was a better predictor of children’s success with language than their general social background.

Most children develop speech and language effortlessly, but some are slow to acquire these skills and go on to struggle with literacy (读写能力) and academic skills throughout their schooling. This project set out to uncover what factors contributed to these problems.

Professor Sue Roulstone said, “These findings are an encouragement to all parents to provide a positive communication environment for their children from the very start of their lives. The project did identify particular aspects of the communication environment, such as having children’s books around and not having the television on too much. But the main message is that, as parents, we can have an impact on how our children learn to talk by providing a range of communication experiences. And the better our children are at talking by the age of two years, the better they will do when they start school.”

1.According to the passage, what is the most important factor contributing to children’s success at school? _____.

A. Their general social background.

B. Being taken to a library as early as possible.

C. Being involved in various activities.

D. Their communication environment.

A. children could naturally have a smooth transition into the educational system

B. the very early years had a big effect on children’s school performance

C. communication with children after they were over two years old was more effective

D. children’s educational future was pre-determined by their parents’ social position

3.The study shows that two-year-old children who have a positive communication environment do better in _____.

A. maths            B. reading

C. writing            D. speaking

4.What is implied in the passage? _____.

A. The research could help children who suffer from learning difficulties.

B. Parents should take their children to school as early as possible.

C. Teachers should teach children how to communicate with their parents.

D. Children who have good language abilities will not have difficulties in class.

Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.

Any owner will tall you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water.
