Passage One There are many commonly held beliefs about glasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eye. 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 the wrong glasses. We have all heard some of the common myths about how eyesight gets back Most people believe that reading in dim light cause 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. But, although eyestrain may cause some pain or headaches, it does not permanently damage eyesight. Another myth about eyes is that they can be replaced, or transferred from one person to another. There are close to one million nerve fibers that connect the eyeball to the brain, and 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 file eyes, some day a full transplant may be possible. Passage Two The incident occurred one morning outside Albert Schweitzer's hospital in the African jungle. A patient had gone fishing in another man's boat the previous night. The owner of the boat thought he should be given all the fish that were caught. Dr. Schweitzer said to the boat owner: 'You are right because the other man ought to have asked permission to use your boat. But you are wrong because you are careless and lazy. You merely twisted the chain of your canoe round a palm tree instead of fastening it with a padlock. Of laziness you are guilty because you were asleep in your hut on this moonlit night instead of making use of the good opportunity for fishing.' He mined to the patient: 'But you were in the wrong then you took the boat without asking the owner's permission. You were in the right because you were not so lazy as he was and you did not want to let the moonlit night go by without making some use of it.' Dr. Schweitzer divided the catch among the fisherman, the boat owner and the hospital. Passage Three Why Seat Belts Are Necessary More than 30,000 drivers and front seat passengers are killed or seriously injured each year. The impact on you of an accident can be very serious. At a speed of only 30 miles per hour it is the same as falling from a third-floor window. Wearing a seat belt saves lives it reduced your chance of death or serious injury by more than half. Who has to wear a seat belt? Drivers or front passengers in most vehicles. If you are 14 or over, it will be your responsibility to wear the belt. lf you do not, you could be fined up to ＄50. It will not be up to the driver to make sure you wear your belt. But it will be the driver's responsibility to make sure that children uruler 14 do not fide in the front unless they are wearing a seat belt of some kind. A very few vehicles have a middle front seat between the front passenger seat and the driver's seat, for example, a bench seat. Your vehicle may be one of them. If just one passenger sits in front, he must wear a seat belt. But if two passengers sit in front, the person sitting in the middle will not have to wear a belt. Medical exemptions Certain people ought not to wear a seat belt because of their health. It may be more risky for them to wear a belt than to be in a road accident without one. But they will not have to wear a belt if they get a valid medical certificate from a doctor. If you think this applies to you, go and tal
