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 problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风)within as little as a few hours after exposure. In one review 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. A separate 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. What can we learn from the text?
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.

Too much eating. Too many unhealthy foods. Too many ads for food. Too few activities. Different reasons are given for America’s weight problem---a problem increasingly shared by other countries. Almost one-fifth of American children and teenagers are overweight.
Schools have been asked to increase physical education, an important tool for public health. However, a recent study has shown an increase in the number of injuries in P.E. classes.
Researchers say one possible reason for this is a decrease in the number of school nurses. Schools without a nurse on duty may be more likely to send an injured child to a hospital.
Another possible reason for more injuries is a change in the traditional idea of physical education. This “New P.E.” expands the kinds of sports that are taught. But activities that some schools offer now, like rock climbing and skateboarding, can also increase the risks, says Cheryl Richardson, who is with the National Association for Sport and Physical Education(NASPE).
She also says not all states require P.E. teachers to be specially trained. Untrained teachers could be less likely to recognize unsafe conditions.
Cheryl Richardson points to one of the study’s findings –that injuries are often the result of contact with a person or a structure. This tells her that the teachers were not giving each student enough space to move around safely.
Six activities produced seventy percent of all injuries: running, basketball, football, volleyball, rugby and gymnastics.
The researchers say larger class sizes are another possible reason for the increase in injuries. Larger classes can mean less supervision(监督). The National Association for Sport and Physical Education says twenty to thirty students in a P.E. class should be the limit.
1.What does the passage mainly discuss?
A. What leads to the weight problem in America.
B. Whether students should have more P.E. classes.
C. Why there have been more injuries in P.E. classes.
D. What kinds of activities are safe for school students.
2.We can know from the third paragraph that__________.
A. nurses are paid more in hospitals than in schools in America.
B. many nurses in American schools don’t have good skills.
C. fewer people choose to become a nurse in America.
D. American schools need more school nurses at present.
3.Which of the following statements is TRUE?
A. P.E. classes become more dangerous for students now in America.
B. Fewer and fewer students are interested in P.E. classes in America.
C. The number of P.E. teachers in schools must be increased now.
D. P.E. classes follow the traditional ideas in physical education.
4.According to Cheryl Richardson,____________.
A. students should do more exercise when they are at school
B. teachers are partly responsible for injuries in P.E. classes
C. the equipment for P.E. classes must be improved in all schools.
D. P.E. teachers should give students more freedom in their classes
