Eating too much fatty food，exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.

Previous studies have linked high exposure（暴露）to environmental pollution to an increased risk of heart problems, but two analyses now show that poor air quality can cause heart attack or stroke（中风） within as little as a few hours after exposure. In one report of the research, scientists found that people exposed to high levels of pollutants（污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. Another study of stroke patients showed that even air that the U.S. Environmental Protection Agency（EPA）considers to be of　 “moderate”(良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.

The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

1.The text mainly discusses the relationship between _________ .

A. heart problems and air quality

B. heart problems and exercising

C. heart problems and smoking

D. heart problems and fatty food

2.The underlined word “modest” in Paragraph 3 most probably means _________ .

A. relatively high　　　　　　　　　　　 B. extremely low

C. relatively low　　　　　　　　　　　　 D. extremely high

3.We can learn from the text that __________？

A. eating fatty food has immediate effects on your heart.

B. the EPA conducted many studies on air quality.

C. moderate air quality is more harmful than smoking.

D. stricter regulations on pollutants should be made.

4.The author’s purpose of writing the text is most likely to _________ .

A. inform　　　　　 B. persuade　　　　　 C. describe　　　　　 D. entertain

第三部分：阅读理解（共20小题，每题2分，满分40分）

Sitting too much is now listed with smoking and junk food as a bad habit that increases your risk of heart disease.

New Australian research shows that half-an-hour in the gym will not make up for the waist-expanding damage caused by spending the rest of the day sitting.

But the good news is that doing chores (家务杂事) in the house or gently walking around the office while on the phone might be enough to keep you fit.

The study joins the growing body of evidence suggesting too much sitting might undo the benefits of exercise.

The study measured the intensity (强度) of physical activities in 168 subjects over seven days. It found that, regardless of how much exercise they did or their total sitting time, those who took more breaks from sitting had lower risk of thick waists and lower levels of blood lipids (脂质).

“Higher levels of blood lipids have been linked to a heightened risk of heart disease,” principal researcher Genevieve Healy of the University of Queensland said. “What the study shows is that there are benefits in just getting up regularly and interrupting your sitting time.”

Researchers behind the Stand Up Australia project have written to the Rudd Government requesting $3.5 million for a two-year study into how long sitting affects health and productivity of workers. The study would also develop and test strategies for reducing sitting time on the job.

The latest study builds on work that is shifting the health promotion focus from purposeful exercise, such as running, to lower intensity activities throughout the day.

The Australian research has been backed up by US studies.

“To hold a body that weighs 77 kilograms upright takes a fair amount of energy from muscles,” said Professor Marc Hamilton from the University of Missouri. “There is a large amount of energy associated with standing every day that cannot be easily replaced by 30 to 60 minutes in the gym.”

56.The study shows that            .

A. exercising for 30 minutes in the gym is good after sitting too long

B. walking is the best physical activity after sitting too long

C. sitting too long in the office causes the waist to expand

D. having breaks from sitting is good for your health

57.What’s the aim of the Stand Up Australia project?

A. To develop and test strategies for reducing working time.

B. To study the reasons for the longer sitting time in the office.

C. To develop and test strategies for reducing sitting time at work.

D. To study the factors influencing productivity of workers.

58.The purpose of the last paragraph is to        .

A. provide a scientific basis for the benefits of standing up

B. compare the effect of standing with exercising in the gym

C. report the new research findings of Professor Marc Hamilton

D. figure out the amount of energy associated with daily standing

59.The health promotion focus used to be on         .

A. purposeful exercise                        B. running

C. lower intensity activities              D. long sitting

60.What’s the best title for the text?

A. Exercise in the Gym Is Out                  B. Your Office Chair Is Killing You

C. A Cause of Heart Disease          D. Good News for Workers

Everyone knows that eating too much junk food is not good to our health. Yet, what is it about junk food that is so completely irresistible(无可抗拒的)? For one thing, it’s everywhere. From chips in fast food restaurants to candy in supermarkets, junk food always seems available. Thankfully, science is now providing new clues to help us reduce snacking.

Make friends with dainty(讲究的) eaters.

Studies have found that people tend to increase or reduce the amount of food they eat depending on what their companions are taking in.

See happy movies and always get the smaller bag of popcorn(爆米花).

According to some experts, people eat up to 29% more popcorn if they are watching a sad or serious movie, compared to when they are watching a comedy. Viewers consumed almost 200 calories more when snacking from a large bucket, as opposed to when given a medium-sized container.

Eat breakfast.

Nutritionists have gone back and forth（来来回回）about the question of how much to eat in the morning, but new studies suggest that consuming a good breakfast is a must. Surveys on long-term weight-loss show that two key factors in keeping weight down are eating breakfast and exercising.

Divide your food and conquer overeating.

Any kind of dividing your food into portions slows down your eating. Any kind of marker makes you aware of what you’re eating and of portion size. Researchers advise reallocating（再分配）snack foods into small plastic bags. It sounds simplistic, but it works.

1.Why do people eat too much junk food though it is bad for our health?

A. It’s delicious from chips to candy.

B. Because it’s available here and there.

C. It’s easily taken everywhere.

D. It’s easily bought in fast food restaurants.

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

A. If people are watching a tragedy, they eat up to 29% more popcorn.

B. People are likely to eat more food when staying with friends.

C. Nutritionists have the same opinion about how much to eat in the morning.

D. People prefer to snack from a large bucket.

3.What will he or she do if he or she wants to lose weight?
