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.

Unlike most other holidays,the history of April Fools’ Day.Sometimes called All Fools’ Day,is not totally clear.The only point in time that can be agreed on as the beginning of this tradition was 1582,in France.Before that year,the New Year was celebrated for eight days,beginning on March 25.The celebration reached the highest point on April 1.With the reform of the calendar under Charles 1X,the the Gregorian calendar(公历，阳历）was introduced,and New Year’s Day was moved to January 1.
However,because in those days communications were not as developed as they are today,many people did not receive the news for several years.Some people refused to accept the new calendar and continued to celebrate the New Year on April 1.These backward people were considered”fools” by other people.They were often sent on “fools” errands（徒劳无益的工作）or were made the targets of jokes.
This developed,over time,into a tradition of playing a trick on someone on the first day of April.The tradition eventually spread to England and Scotland in the eighteenth century.It was later introduced to the American colonies of both the Britain and France.April Fools’ Day thus developed into an international fun feast,so to speak,with different nationalities specializing in their own kind of humor at the expense of their friends and families.

No one knows why we sleep,but it’s certain that we need to.People who are prevented from sleeping begin to suffer obvious effects after a few days—they think less clearly,and they fall asleep during the working hours;some may have hallucinations（幻觉）.
There are no rules about sleep.Generally speaking,grown-ups sleep about 7 and half hours each night and probably more than 60 percent get between seven and eight hours.But perhaps eight percent are quite happy with 5 hours or lees,and four percent or so find that they want ten hours or more.If you feel all right,you’re probably getting enough sleep.The important thing is not to worry how much other people get—their needs may be different.Exercise doesn’t seem to need to increase the sleep time—office workers,for example,sleep for about as long as people doing physically active work.
Children sleep more than grown-ups---perhaps 14 to 18 hours soon after birth,going down to grow-up levels by early teenage.Sleep patterns also tend to be different in the elderly,who may sleep less at night than they did when younger,find sleep getting more broken,and often make it a rule to sleep during the daytime.

Dear Li Hua,
I am glad to receive your letter. I can understand how sad you are as they have to transfer to other school. But everything will be fine when you adapt to your new surrounding. In your letter, you asked me about my first school. In my memory, my first school was very large with each classroom beautiful decorated. There was a big square lies in the center of the schoolyard. And I could have good view of the square from my classroom windows. My favorite teacher was my English teacher which was patient with me. Besides, I had met my best friend Peter in the school, to whom I still keep in touch even though we are in different schools now. I hope you will make new friends but enjoy your time in the new school.
