18.Are You Right Handed or Left Handed?
Which hand do you use when write?About 8to 15percent of people are left handed.They often have to use tools that are designed for right-handed people.So it is difficult for left-handers to use most tools.If you are right handed,try this experiment:Take a knife with your left hand and try cutting a potato into pieces.Don't be surprised if you feel awkward(别扭的).
In the past,people thought it was strange to use the left hand.Young students looked down upon their left-handed classmates.Some children were even punished for using their left hand to write.But these days parents and teachers have accepted that.In almost every school in the world,left-handed students can use their left hand to write.
What causes people to be left handed or right handed?Experts have searched long and hard on this.They conclude(得出结论) that left-handed people are left handed for the same reason that right-handed people are right handed.One out of every ten people just is a left-handed people are right handed.One out of every ten people just is a left-hander.It's simply like the color of our eyes-some people have brown eyes,while some others have black eyes.
However,may researchers think that left-handers and right-handers are different in some aspects.Right-handers are more talkative and outgoing than left-handers.Many right-handed people understand spoken words better.For example,after they listen to directions to a supermarket,they can find it easily.Right-handers are good at organizing people,too.They are also better basketball guards.Just ask Yao Ming.
