【题干】The Truth about Left-Handed People
About 90% of people in the world today are right handed. The other 10% are
left-handed, including Obama, the President of the US. Every day, left-handed
folks quietly face problems. It could be something as simple as driving a car or
using a can opener.
Why are so few of us left-handed? One theory is that handedness (hand
preference) could be a result of genetics. Scientists say that there are two genes
(基因) associated with handednss. One is the D gene. It is more frequent in the
population and promotes (促成) right hand preference. The other is the C gene. It
has the ailiy to promote a perene for cither hand. When he C gene is present,
there is a 50% chance hat a person could be ighth or le-handed
Another theory
has to do with human brains, which are made up of two
halves. If the left half is more powerful, then one
is most likely right-handed. But
wih lethandcrs. itis more coplcae. Seveany peren of them are alo
left-brain dominant (占优势的). The other 30% have right-side dominant brains.
During the 18th and 19th centuries, left-handedness was considered a
disability. But not all of the myths about left-handers are bad. One myth suggests
that they are more creative and smarter than the right handers. So far scientific
research has yet to find any truth to these claims. In fact, a 2013 survey out of
New Zealand found that left-handers and right-handers were the same.
Life might be a lttle more complicated for left-handers when it comes to
cutting a piece of paper or opening a bottle of wine. However, it seems to be a
good sign if you are trying to make it to the White House.
