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 lead to heart attack or stroke(中風(fēng))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 US 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.

As the morning school bell rings and students rush in, teenagers in one classroom settle onto mats and meditation(冥想) pillows. They fail silent after the teacher taps a “singing bowl”.

These students are in a for-credit, year-long mindfulness class, which is meant to ease youth anxiety and depression and to prevent violence. For 90 minutes, three days a week, they practice a mix of yoga, sitting, and walking meditation, deep breathing, journaling, and non-judgmental listening.

Yoga and meditation have gained popularity among Americans in recent decades, supported by studies showing benefits to emotional, mental, and physical health. The centuries-old practices have roots in eastern religions, but Western culture has long focused on physical postures (姿勢), breathing, and relaxation techniques.

Some people have greeted the move with less than enthusiasm. Last year, an elementary school in Ohio ended its mindfulness program after parents complained it was too closely linked to religion. But many school districts are reporting success. In Richmond, California, schools have reported drops in school problems among low-income, at-risk youths. The school district in South Burlington, Vermont, introduced a successful mindfulness course as part of a health and wellness program, and now administrators there have advocated mindfulness into K-12 curriculums.

Two years ago, Caverly Morgan developed the after-school mindfulness program teamed up with Allyson Copacino, who teaches yoga. After hundreds of students signed up, Principal Brian Chatard took note. The school was dealing with a student' s suicide (自殺), and few resources were available to address students’ emotional and mental health.

“High school is the hardest period of time for kids,” Mr. Chatard said. “You’ve got emotional changes, physical changes, and all the social pressures. It’s also the onset of mental illness for some kids, depression hits, and there’s the pressure of college and sports. All these things kids do is overwhelming without having a strategy (策略) to deal with it. ” And now schools all over the country are introducing the practices.

1.What do Western people value more about yoga and meditation?

A. Non-judgmental listening. B. Religious meaning.

C. Physical benefits. D. Journaling.

2.What can we infer about the mindfulness class?

A. It is supported by parents.

B. It relives pressure of students.

C. It mainly builds students up physically.

D. It improves students’ academic performance.

3.Who started the mindfulness class?

A. Administrators. B. Brian Chatard.

C. Caverly Morgan. D. Allyson Copacino.

4.What is Mr. Chatard’s attitude towards the program?

A. Supportive. B. Concerned. C. Doubtful. D. Reserved.

We’ve all experienced peer pressure (同伴壓力). It happens to everybody. However, people have different reactions. Confident people refuse to do things they don’t want to do, but shy and anxious people often give in. It may be because they want to be liked. It may be because they worry that their friends will make fun of them, or perhaps they’re just curious about trying something new. 1.

It’s hard being the only one who says no and the question is: how do you do it? 2. If you think that missing maths, or smoking, or going somewhere you know your parents wouldn’t like is a bad idea then the answer is simple: don’t do it. It’s your decision, nobody else’s. You don’t need to be aggressive. You don’t need to shout and scream, but you must be confident and you must be firm. You need to say, “No thanks. I don’t want to do that.”

Being on your own against everybody else is very hard, so it can really help to have at least one other peer, or friend, who will say no too. 3. You want friends who will support you when you’re in trouble. You don’t want people who will always agree with the majority. Remember, the most popular people aren’t always the most trustworthy.

4. — You can learn a lot from people your own age. They can teach you great football skills or the best way to do your maths homework. They can recommend music and advise you on fashion. And don’t forget you can tell them things too, and that always feels great. So, find friends who have similar interests. And remember, friendship isn’t about feeling depressed and guilty. 5.

A. Choose your friends carefully.

B. Firstly, you must decide what you believe in.

C. It’s about sharing experiences and having fun.

D. Of course, peer pressure isn’t completely bad.

E. It may be because they were all born to be stubborn.

F. Depression and guilt will surely give you peer pressure.

G. Whatever the reason, some people end up doing things they really don’t want to.
