With the large number of dogs roaring through our communities， people need to know the facts about
rabies (狂犬病)， a fatal disease caused by animal bites. Despite vaccination (接種疫苗) programs， rabies is still very prevalent， and will continue to be a serious public health problem for
many years to come.
Rabies strikes the central nervous system and brings on choking， convulsions (抽搐) and inability to swallow liquids. It can even cause death. If you or anyone in your family is bitten
by dog， cat or other animal， you should not panic， but thoroughly wash the wound with plenty of
soap and water and rush to nearby hospital for immediate treatment. If you own the animal which did the
biting， you should immediately call a veterinarian for advice and make sure the public health
authorities know when and where the biting took place and who was bitten.

The findings are based on a German study of almost 700 people who suffered heart attacks. The patients described their activities during the four days before their heart attack. Researchers found that those who had been in traffic were three times more likely to have a heart attack within one hour, compared to those who had not been in traffiC. Most of those in the study had been traveling by car. But some had been on bicycles and others were on buses.
Research shows that people in cars and buses are exposed to ten times the amount of pollutants as people walking on the street. That is largely because they breathe in the particles and gasses released from the vehicles in front of them.
Over time, these small particles speed the buildup of a sticky substance in the blooD. This can cause blockages(阻塞) to form. in the arteries(动脉) around the heart and lead to a heart attack.
Other studies have also linked heart trouble to stress, similar to the kind that people face while driving in heavy traffiC. But the researchers of the latest study say they do not know whether the increased heart attack risk was the result of stress or pollution. They suggest it may be a combination of stress, noise and pollution. Experts say the research shows the need fro cleaner vehicles and better city planning.
9.According to the study, which of the following ways is the safest in traffic？
A. Driving a car
B. Walking on the street
C. Taking a bus
D. Riding a bicycle
9.From among the 700 people who suffered heart attacks we learn that ______.
A. those who have been in traffic are three times as many as those who have not
B. those who have been in traffic for more than one hour are most likely to suffer heart attacks
C. the risk of a heart attack is three higher among those who have been in traffic than those who have not
D. Most of the subjects (实验对象) felt uncomfortable during the four days before the attack
9.The particles released from vehicles ______.
A. build up in the blood
B. become blockages in the arteries
C. make the blood more sticky
D. do harm to the heart
9.According to the studies, which of the following is NOT a likely cause of heart attack？
A. Stress
B. Noise
C. Air pollution
D. Traffic accident
9.What suggestion do experts make to lower the risk？
A. Reducing traffic as much as possible.
B. Living away from nose.
C. Planting more trees in the city.
D. Making vehicles clean.
Heart failure, for example, appears to have seasonal and temporal patterns. A higher percentage of heart attacks occur in cold weather, and more people experience heart failure on Monday than on any other day of the week. In addition, people are more susceptible to heart attacks in the first few hours after waking. Cardiologists first observed this morning phenomenon in the mid-1980, and have since discovered a number of possible causes. An early-morning rise in blood pressure, heart rate, and concentration of heart stimulating hormones, plus a reduction of blood flow to the heart, may all contribute to the higher incidence of heart attacks between the hours of 8:00 AM and 10:00 AM.
In other studies, both birthdays and bachelorhood have been implicated as risk factors. Statistics reveal that heart attack rates increase significantly for both females and males in the few days immediately preceding and following their birthdays. And unmarried men are more at risk for heart attacks than their married counterparts. Though stress is thought to be linked in some way to all of the aforementioned risk factors, intense research continues in the hope of further comprehending why and how heart failure is triggered.
What does the passage mainly discuss？
A．Risk factors in heart attacks.
B．Seasonal and temporal patterns of heart attacks.
C．Cardiology in the 1980s.
D．Diet and stress as factors in heart attacks.
