Most people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed 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 hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person’s hands and eyes work together, controls the left hand. The left-side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as 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 because their main brain is damaged when they are born. However, this doesn’t happen to everyone, so scientists guess there must be another reason 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-handed or left-handed according to the chance and the people they work or live with.
Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don’t have to.

Taiwan will finalize a plan by the end of June to open up the island to tourists from mainland China, though no date has been fixed for formal implementation(执行), an official at the Mainland Affairs Council(MAC)said on Monday.
The official said the reports in the local press on Monday that the MAC has decided to postpone its plan to announce the implementation of the new plan on July 1 were inaccurate.
The official said cooperation between different organizations was still underway.The United Daily news quoted the director of the MAC’s legal affairs department, Liu Thehsun, as saying the plan to open up to mainland tourists would not be implemented as scheduled due to a lack of cross-strait communication.
Although relevant authorities, including the Bureau of Immigration and the Tourism Bureau, have complete reports on how to deal with visitors from mainland China, the decision has been taken not to press, ahead with announcement of the plan’s implementation on the first of July, Liu was quoted as saying.
The report also said that while no restrictions would be imposed on the mainland visitors in terms of age or residence in China, the visitors would need to hold a steady job or have more than 50,000RMB(about 6,000, U.S.dollars)in bank savings before they would be eligible(有资格的)to visit Taiwan.
In addition, Taiwan bound mainland tourists would have to come as part of a tour group and would be allowed to stay a maximum of 10 days each time.
The number of mainland tourists allowed to enter the island would also initially be limited to 1,000 people a day.
Although most people from Taiwan are free to travel to China, only a small number of mainland Chinese have been able to visit the island due to restrictions imposed by both sides of the Taiwan Strait after the end of a civil war in 1949.
