【题目】Being Left-handed in a Right-handed World

The world is designed for right-handed people, but a tenth of the population prefer the left. 1 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.2 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. 3 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. 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. 4 A person giving directions will put his left hand behind him and try to point with his right hand if necessary. In some Asian countries, eating with the left hand is considered impolite.

5 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.

A. In other words, left-handers are born that way.

B. Left-handedness used to be regarded as a disability.

C. The unfavorable associations of the use of the left hand among cultures are varied.

D. Why do they prefer to use their left hand rather than their right hand for routine activities?

E. Why do some parents force their left-handed children to become right-handed when writing?

F. In Ghana, pointing, gesturing, giving or receiving items with the left hand is considered rude.

G. Fortunately, nowadays most societies and cultures no longer reject left-handedness like before.
