The Truth about Left-Handed People
About 90% of people in the world today arc right-handed. The other 10% arc 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-hand preference. The other is the C gene. It has the ability to promote a preference for cither 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 arc made up of two halves. If the left half 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 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 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 arc nine times as many as the left-handers.

Are some people born clever, and others born stupid? Or is intelligence(智力)developed by our environment and our experiences? Strangely enough, the answer to both questions is yes. To some extent our intelligence is given to us at birth and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person’s intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways. It is easy to show that intelligence, to some extent, is something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random from the population, it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical twins(双胞胎)they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth. Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.

The environmental crisis is the result of success in cutting down the morality of infants (which has given us the population explosion), success in increasing farm output sufficiently to prevent mass famine, success in getting people out of the tenements of the 19th century city and into the greenery anti privacy of single family home in the suburbs (which has given us urban sprawl and traffic jams). The environmental crisis, in other words, is the result of doing too much of the right sort of thing at large.
To overcome the problems that success always creates, one mast build on it. But where to start? Cleaning up the environment requires determined, sustained effort with clear targets and deadlines it needed, above all, concentration of effort. Up to now we have tried to do a little bit of everything, what we ought to do first is to draft a list of priorities.
