The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choice and do not like to see it restricted when it is within the legal and moral boundaries of society. The structure of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, we can smoke, drink excessively, refuse to wear seat belts, eat whatever foods we want, and live a completely sedentary life style without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.
A multitude of factors, both inherited and environmental, influence the development of health related behaviors, and it is beyond the scope of this text to discuss all these factors as they may affect any given individual. However, the decision to adopt a particular health related behavior is usually one of personal choices. There are healthy choices and there are unhealthy choices. In discussing the morals of personal choice, Fries and Grapo drew a comparison. They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide. Thus, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors that are associated with a statistical probability of increased vitality and longevity.
The concept of personal choice concerning health is important because ____.
| A．personal health choice help cure most illness |
| B．it helps raise the level of our medical knowledge |
| C．it is essential to personal freedom in American society |
| D．wrong decisions could lead to poor health |
Sound personal health choice is often difficult to make because ____.
| A．current medical knowledge is still insufficient |
| B．there are many factors influencing our decisions |
| C．few people are willing to trade the quality of life for the quantity of life |
| D．people are usually influenced by the behavior of their friends |
To knowingly allow oneself to pursue unhealthy habits is compared by Fries and Crapo to ____.
| A．improving the quality of one’s life |
| B．limiting one’s personal health choice |
| C．deliberately ending one’s life |
| D．breaking the rules of social behavior |
Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age.
Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception(观察力) of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.
The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time.
Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here’s where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles — making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles — so it appeared to be smaller than the real smaller orange circle.
When young children aged 4 to 6 looked at these tricky pictures, they weren’t fooled — they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time.
As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they’re more likely to fall for this kind of visual trick.Doherty and his team of scientists did an experiment to evaluate .
| A．children’s and adults’ eye-sight |
| B．people’s ability to see accurately |
| C．children’s and adults’ brains |
| D．the influence of people’s age |
When asked to find the larger circle, .
| A．children at 6 got it wrong 79 % of the time with no gray ones around |
| B．only adults over 18 got it right 95% of the time with gray ones around |
| C．children at 4 got it right about 79 % of the time with gray ones around |
| D．adults got it right most of the time with gray ones around |
According to the passage, we can know that .
| A．a smaller orange circle appears bigger on a white background |
| B．an orange circle appears bigger than a gray one of the same size |
| C．a circle surrounded by other circles looks bigger than its real size |
| D．a circle surrounded by bigger ones looks smaller than its real size |
Visual context may work when children get older than .
| A．4 | B．6 | C．10 | D．18 |
Why are younger children not fooled?
| A．Because they are smarter than older children and adults. |
| B．Because older people are influenced by their experience. |
| C．Because people’s eyes become weaker as they grow older. |
| D．Because their brain can hardly notice related things together. |
