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 left 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.
Did you know that cigarette butts(烟头) are the most common form of rubbish in our lives? People throw about 4.5 trillion(万亿) of them into the environment every year. Cigarette butts can kill fish, and they have been found in the stomachs of sea turtles, birds and other wildlife. {#blank#}1{#/blank#}.
Now, Dutch company TechTics plans to help solve the cigarette problem with its BeachBot (BB).{#blank#}2{#/blank#}Even part of the butt hidden in the sand can be found. At just 80 centimeters wide, BB has four wheels, two cameras and two arms to pick up cigarette butts. {#blank#}3{#/blank#}Once it finds cigarette butts, BB just needs to place them into a bin(垃圾箱) that it carries. After it finishes cleaning, people deal with the waste properly.
However, BB still needs help to tell the difference between things like a cigarette butt and a small seashell(海贝壳).{#blank#}4{#/blank#}Using this app, anyone with a smartphone can send BB photos of cigarette butts to help the robot learn to know them. Besides that, TechTics works on a pair of smaller robots that can look for cigarette butts. They tell the larger robot where the butts are so it can pick them up.
{#blank#}5{#/blank#}But while the robot works well without wasting time, TechTics wants to get people to litter less. If people stop throwing their cigarette butts onto the beach, robots like BB wouldn't be necessary.
A. The way this robot works is very simple. B. To do this, the company turns to Microsoft Trove. C. It is a beach-cleaning robot that uses AI to find cigarette butts. D. During its first demo, BB picked up 20cigarette butts in 30 minutes. E. Though they're everywhere, people don't notice them because they're so small. |
