It is an everyday observation that animals are born, grow, and mature, then begin to lose
some of their capabilities, and finally die. This loss of capabilities is progressive, irreversible and common for all members of a species and is called aging. In humans it shows in many ways, some very visible: decline in height, shrinkage of muscle, thinning and graying of hair, and wrinkling of skin. Internally, and even more significantly, there is the progressive loss of cells in the brain, kidneys, and other vital organs. This cell loss has resulted in stoppage of a vital process. Whatever the reason, important tissues ranging from the muscles to the brain shrink and become less competent with age. Many of these changes are reflected in functional decline. Not only do nerve cells at levels from the brain to the spinal cord diminish, but also those that remain conduct impulses at a slower rate so that the reaction time of the older animal is slowed. Memory often shows a decline.

Another widespread decline is in the loss of cells involved in the hearing process. The loss is most masked for high pitches and may require tile assistance of a battery-operated hearing aid. More subtle are such declines as those in the processes involved with being immune to disease, which result in a lessoned ability of the older organism to cope with infection. Indeed, pneumonia is one of the most common causes of death among the elderly population of most nations.
Mixed with true aging processes are disease processes that may be so common as to be mistaken for aging. For instance, the buildup of deposits of fatty materials in arteries tends to be progressive with aging; everything else being equal, the narrowing of arteries results in such serious illnesses as stroke or heart attack, occurring with increasing frequency as an individual ages.
It is now recognized that arteriosclerosis is the result of many factors, not only genetic but also environmental high blood pressure, high saturated-fat diets, and smoking, the effects of which be come more obvious with the passage of time. It is therefore an age-related, but not a universal aging, process and can thus usually be controlled.
As far as aging is concerned ______.
A．the changes inside human bodies are more important than exterior ones
B．the loss of competence is more significant than that of cells
C．the shrinkage of muscles is more significant than the decline in height
D．the thinning of hair is less important than the wrinkling of skin

阅读理解 Researches say people traveling in traffic are three times more likely to suf
fer a heart attack. They say the risk of a heart attack is greatest within an hour of being in traffiC.
点击查看答案
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.
