浙江省杭州市2018届英语高考模拟试卷三
What do Leonardo da Vincii, Marie Curie, and Albert Einstein have in common? They were all left-handed, along with other famous people including Brad Pitt Prince William, and Barack Obama. In fact, an estimated 13 percent of the world's population may be left-handed and still most people around the world are right-handed.
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, whereas 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 birth, which makes them left-handed. However, if this theory were true, it would not explain why the percentage of left-banded people is so similar in every society, when birth conditions vary so much from society to society.
Whatever the reasons behind it, people's attitudes toward left-handedness have changed a lot over the years. Statistics show that although 13 percent of young people (10-20 years old) are left-handed, only 6 percent of the elderly are left-handed. 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 on nor are they considered abnormal. For most people today, either case is perfectly acceptable.
