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. Most of the people shown in these works were right-handed, so the scientists guessed that right-handedness had always been common through history. Today, only about 10% to 15% of the world's population are 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. 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. ①If 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 ②they don't have to.

A strange thing happens to nearly everybody. At night, people turn off the lights, pull up the covers and close their eyes. Six or seven sleeping hours later, they wake up again. Strange, isn't it?
Sleep ①puzzles science. Scientists and doctors would rather talk about why one can't fall asleep. They are not sure what causes sleep. The best conditions for sleep are good health and meal neither too big nor too small. No worries and a comfortable place are important, too.
Strange things happen during sleep. For example, you move often. You would feel tired if you didn't. You also dream. Part of your brain is still awake when you sleep. Dreaming happens when the memory and imagination in parts of your brain are still awake. Experiments have shown most of us dream in color. Bad dreams may be caused by stomachache. Don't worry if you dream. Some great stories and poems were begun while their writers slept.
