Private Car in AmericaThe private automobile(私家车)has long played an important role in the United States. In fact, it has become a necessary and important part of the American way of life.

However, when teenage children have the use of the car, their parents can’t keep an eye on them. There is a great danger if the driver has been drinking alcohol or taking drugs, or showing off by speeding or breaking down traffic laws. Mothers of victims(受害者)of such accidents have formed an organization called MADD(Mothers Against Drunk Driving). These women want to prevent further tragedies(悲剧). They have worked to encourage the government to limit the youngest drinking age. Students have formed a similar organization SADD (Students Against Drunk Driving) and are spreading the same message among their friends.For many Americans, the automobile is a necessity.

The truth about left-handed peopleAbout 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 handedness. One is the D gene. It is more frequent in the population and promotes（促成）right-handed preference. The other is the C gene. It has the ability to promote a preference for either hand. When the C gene is present, there is a 50% chance that a person could be right-or left-handed.Another theory has to do with human brains, which are made up of two halves. If the left hand is more powerful, then one is most likely right-handed. But with left handers, it is more complicated. Seventy percent of them are also left-brain dominant（占优势的）. The other 30% have right-side dominant brains.During the 18thand 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 little 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.The right-handers are nine times as many as the left-handers.
