Being Left-handed in a Right-handed World

The world is designed for right-handed people, but why does a tenth of the population

prefer the left? 36

The answer to it remains a bit of a mystery. Since scientists have noticed that left-handedness

tends to run in families, it's assumed that left-handedness has a genetic（基因的）component to

it. 37 In fact, identical twins, who share the same genes, can sometimes prefer to use

different hands. There are also plenty of theories on what else might determine which hand you

write with, but many experts believe that it's kind of random.

Historically, the left side and left-handedness have been considered a negative thing by

many cultures. 38 In some areas, the left hand became known as the "unclean" hand. In

many religions, the right hand of God is the favored hand. For example, Jesus sits at God's

right side. God's left hand, however, is the hand of judgement. Various activities and

experiences become rude or even signs of bad luck when the left hand becomes involved. In

some parts of Scotland, it is considered bad luck to meet a left-handed person at the start of a

journey. 39 A person giving directions will put their left hand behind them and even

physically try to point with their right hand if necessary. In some Asian countries, eating with

the left hand is considered impolite.

40 People come to realize that left-handedness is natural. People even noticed that

many famous people are left-handed, including Benjamin Franklin, Leonardo Da Vinci, and

Charlie Chaplin. Some researchers find out that lefties are more creative and can deal with

abstract thinking better. The left-handedness is more easily adaptable to the right-handed

world as well. Being left-handed is no longer a sad story now; instead, it is a wonderful gift or

maybe it is something you should take pride in. 高考英语模拟试题库  http://www.17xuexiba.com/yy/
