Did you ever see a fish with its very own lights? Some fish have built-in lights. That is, the lights are really part of the fish’s body! One such fish lives in the Red Sea. It is called the “flashlight fish” because it has special body parts, or organs, that give off light.
The flashlight fish has one light organ underneath (在下面）each eye. These lights are bright and greenish in color, and they are always “on”. But a flashlight fish can hide its lights by raising an extra (额外的）piece of skin up over each organ. Then, when the fish lowers the skin,the lights can be seen again.
What are these special lights for? The light organs help the fish find food at night along the Red Sea reefs (暗礁).They also help the fish run away. Usually,the lights are flashed “on” and “off’ about once every 20 seconds. But when the fish is worried, it will blink (眨眼）its lights about 75 times in 1 minute. Can you imagine 20 or 30 flashlight fish blinking their lights all at the same time?

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(人口) 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 more 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.
1.How many people in the world are left-handed now?
A.Less than one sixth. B.More than a half.
C.About 40%. D.The passage doesn’t tell us.
2.According to the passage, which of the following is NOT true?
A.No one really knows what makes a person become right-handed.
B.Left-handedness is cleverer than right-handedness.
C.Today children are not made to use their right hands only.
D.Scientists think there must be some reason why people become left-handed.
3.The best title for this passage is _______
A.Scientists’ New Inventions B.Left-handed People
C.Which Hand D.Different Brains, Different Hand
