阅读理解。 Most people around the world are right

题文

阅读理解。      Most people around the world are right-handed. This also ems to be true in history. In 1997, scientists studied works (作品) of art made at different times from 15,000 B.C. to the 1950s. Most of the people shown inthe works are right-handed, so the scientists guesd that right-handedness has always been common through history. Today, only about 10% to 15% of the world's population is left-handed.       Why are there more right-handed people than left-handed ones? Scientists now know that a person's two hands each have their own jobs. For most people, the left hand is ud to find things or hold things. The righthand is ud to work with things. This is becau of the different work of the two sides of the brain (大脑). The right side of the brain, which makes a person's hands and eyes work together, controls the left hand. The leftside of the brain, which controls the right hand, is the centre for thinking and doing problems. The findingsshow that more artists should be left-handed, and studies have found that left-handedness is twice as commonamong artists than among people in other jobs.       No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed becau their main brain is damaged (损害) when theyare born. However, this doesn't happen to everyone, so scientists guess there must be another reason (原因), why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene (基因) for right-handedness, he/she may become either right or left-handed accordingto the chance (偶然性) and the people they work or live with.       Though right-handedness is more common than lefthandedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to u their right hands like other children, but today they don't have to. 1.
