Section B

Passage One

There are many commonly held beliefs about eye glasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of vision if they have glasses inappropriate for their eyes.

We have all heard some of the common myths about how eyesight gets bad. Most people believe that reading in dim light causes poor eyesight, but that is untrue. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bed, and watching too much television. However, although eyestrain may cause some pain or headaches, it does not permanently damage eyesight.考试网

Another myth about eyes is that they can be replaced, or transferred from one person to another. There are close to one million nerve fibres that connect the eyeball to the brain, as of yet it is impossible to attach them all in a new person. Only certain parts of the eye can be replaced. But if we keep clearing up the myths and learning more about the eyes, some day a full transplant may be possible.

Passage Two

When people care for an elderly relative, they often do not use available community services such as adult daycare centers. If the caregivers are adult children, they are more likely to use such services, especially because they often have jobs and other responsibilities. In contrast, a spouse usually the wife, is much less likely to use support services or to put the dependent person in a nursing home. Social workers discover that the wife normally tries to take care of her husband herself for as long as she can in order not to use up their life savings. Researchers have found that caring for the elderly can be a very positive experience. The elderly appreciated the care and attention they received. They were affectionate and cooperative. However, even when caregiving is satisfying, it is hard work. Social workers and experts on aging offer caregivers and potential caregivers help when arranging for the care of an elderly relative. One consideration is to ask   parents what they want before they become sick or dependent. Perhaps they prefer going into a nursing home and can select one in advance. On the other hand, they may want to live with their adult children. Caregivers must also learn to state their needs and opinions clearly and ask for help from others especially brothers and sisters. Brothers and sisters are often willing to help, but they may not know what to do
