Most people around the world are right-handed. This fact also seems to have held true throughout history. In 1977, scientists studied works of art made at various times in history, starting with cave drawings from 15,000 B.C. E. and ending with paintings from the 1950s. Most artists of these works are right-handed, so scientists guessed that right-handedness has always been common. Despite the prevalence of right-handedness, left-handedness presents its own unique array of characteristics and tendencies. Many researchers claim to have found relationships between left-handedness and various physical and mental characteristics, such as blond hair, blue eyes, vegetarianism, and sleep difficulties. Other studies have found a higher-than-normal level of left-handed people in certain occupations, including professional baseball and tennis players, architects, lawyers, and so forth. However, some of these connections are very weak, and others haven't been proven. What makes a person become right-handed rather than left-handed? As yet, no one really knows for sure. One simple idea suggests that people normally get right-handedness from their parents. Studies have found that two right-handed parents have only a 9.5 percent chance of having a left-handed child, while two left-handed parents have a 26 percent chance of having a left-handed child. Another common theory is that left-handed people suffer mild brain damage during their birth. Whatever the reasons behind it, people's attitudes toward left-handedness have changed a lot over the years. Left-handed children used to be punished until they began using their right hand like other children, but today people who are left-handed are no longer looked down upon nor are they considered abnormal. Statistics show that although only six percent of the elderly are left-handed, 13 percent of young people (10-12 years old)are left-handed. This shift indicates a greater social acceptance and understanding of differences in individual characteristics. For most people today either case is perfectly acceptable. There are even a number of shops now that specialize in selling products designed for left-handed people, such as left-handed scissors, can openers, guitars, and even a left-handed camera. Don't you think it's wonderful? 1)From studying works of art, what have the scientists learned?A. Left-handed people are better artists.B. Most artists in history were right-handed.C. Right-handed people create more abstract art.D. Cave drawings were drawn with the right hands. 2)What, though not proven yet, has been found by many researchers?A. Left-handed people are usually professional.B. Left-handed people are good at doing certain jobs.C. Left-handedness can be caused by doing certain jobs.D. Left-handedness is linked with people's characteristics. 3)One suggested idea about what makes a person right-handed is ________.A. the genes from the person's parentsB. the environment where the person livesC. the severe brain damage at the person's birthD. the serious illness that the person experienced 4)What would happen to children of two left-handed parents from the studies in Para. 3?A. They are more likely to become left-handed.B. They are more likely to become vegetarianism.C. They are 9.5 percent more likely to become lawyers.D. They are 26 percent more likely to use both hands equally well. 5)From the passage, what can we learn about left-handedness?A. Left-handedness has aroused little attention.B. Left-handedness has caused a lot of problems.C. People today treat left-handedness the same as in the past.D. People today have positive attitudes toward left-handedness.
