47．Physical activity is important in preventing cardiovascular（心血管的）disease in young people so long as they don't undertake very intense activity on days when air pollution levels are high，according to a recently released study.
Until now，little has been known about the relationships between the health benefits of physical activity taking place outdoors and the potentially harmful effects of air pollution.Previous research by the authors of the current study had investigated the question in middle-aged people at a single point in time，but this is the first time that it has been investigated in young adults aged between 20-30 years over a period of several years.In addition，the researchers wanted to see what happens when people increase or decrease their physical activity over time.
At each health check-up，the participants completed a questionnaire asking about their physical activity in the past seven days and this information was changed into units of metabolic equivalent task（MET，代謝當(dāng)量任務(wù)）minutes per week（MET-mins/week）.The participants were divided into four groups：0，1-499，500999 and 1000 or more MET-mins/week.People are recommended to do 500-999 MET-mins/week and this can be achieved by；for example，running，cycling or hiking for 15-30 minutes five times a week，or brisk walking，doubles tennis or slow cycling for 30-60 minutes five times a week.
The researchers used data to calculate annual average levels of air pollution，in particular the levels of small particulate matter tat are less than or equal to 10 or 2.5 microns in diameter，known a PM10 and PM25.
Overall，the results show that physical activity is associated with a lower risk of developing cardiovascular disease among young adults.However，when air pollution levels are high，exercising beyond the recommended amount may offset or even reverse the beneficial effects.The study cannot show that air pollution causes the increased cardiovascular risk，only that it is associated with it.
（1）What can we know from Paragraph 2？
A．Outdoor physical activity harms our health.
B．Exercising isn't advised on serious air pollution days.
C．A first in-depth survey has been done on young adults.
D．Middle-aged people have been the ideal research target.
（2）How do the results come out？
A．By doing research on young adults.
B．By collecting PM 10 and PM2.5 data.
C．By making experiments on middle-aged people.
D．By studying a questionnaire on physical activity.
（3）What do we know about the result？
A．Air pollution leads to cardiovascular disease.
B．Cardiovascular disease relates to air pollution.
C．More physical exercise benefits young people.
D．Young adults seldom develop cardiovascular disease.
（4）What would be the best title for the passage？
A．Physical activity & air pollution：when to do more or less physical activity
B．Physical activity & health benefit：how to prevent cardiovascular disease
C．Physical activity & air pollution：what to do with high air pollution levels
D．Physical activity &health benefit：how to maximize the health benefits of exercising組卷：2引用：1難度：0.5
