cancer, intelligence Such news stories may lead us to believe our lives are being revolutionized by
genetic discoveries. We may be close to changing and getting rid of mental illness, for example and
identify the causes of crime, personality, and other basic human weaknesses.
But these hopes, it turns out, are based on faulty assumptions about genes and behavior.
In many cases, people are motivated to accept research claims by the hope of finding solutions
for frightening problems, like breast cancer. Accepting genetic causes for their characteristics can
relieve guilt about behavior they want to change but can't. Efforts made to fight against them, at
growing expense, have made little or no visible progress. The public wants to hear that science can
help.
Meanwhile, genetic claims are being made for many ordinary and abnormal behaviors, from
addiction to shyness and even to political views and divorce . If who we are is determined from
pregnancy, then our efforts to change or to influence our children may be useless. There may also
be no basis for insisting that people behave themselves and obey laws. Thus, the revolution in thinking
about genes has great consequences for how we view ourselves as human beings.
Most claims linking emotional disorders and behaviors to genes are statistical in nature. The
research finds are insufficient for deciding that alcoholism or manic-depression (躁狂抑郁症患者)
is inherited. In the late 1980s, genes for manic-depression were identified by teams of geneticists. The
claims have now been definitively proved wrong.
Genetic data on the major mental illnesses make it clear that they can't be reduced to purely genetic
causes. According to Myrna Weissman, Ph.D., Americans born before 1905 had a 1 percent rate
of depression by age 75. Among Americans born a half century later, 6 percent become depressed
by age 24! Similarly, while the average age at which manic-depression first appears was 32 in the mid
1960s, its average beginning today is 19. Only social factors can produce such large shifts in rate and
age of beginning of mental disorders in a few decades.
Scientists actively debate whether disorders like alcoholism are more or less biologically driven.
If they are mainly biological-rather than psychological, social, and cultural-then there may be a genetic
basis for them. In 1990,Kenneth Blum, Ph.D., of the University of Texas, and Ernest Noble, M.D.,
of the University of California, Los Angeles, found a certain gene in 70 percent of a group of alcoholics,
but in only 20 percent of a non-alcoholic group. But in 1993 Joel Gelernter, M.D., of Yale and his
colleagues surveyed all the studies that examined this gene and alcoholism. Different from Blum and
Noble's research, the results were that 18 percent of non-alcoholics, 18 percent of problem drinkers,
and 18 percent of severe alcoholics all had the gene. As for Blum and Noble's work, a more reasonable
model is that genes may affect how people experience alcohol. Perhaps some people's nerves are more
activated by alcohol. But although genes can influence reactions to alcohol, they cannot explain why
some people continue drinking to the point of destroying their lives.
Therefore, claims that our genes cause our problems, our misbehavior, even our personalities are
more a mirror of our culture's attitudes than a window for human understanding and change.

university found that 9 percent of communication time is devoted to writing, 16 percent to reading, 30
percent to speaking and 45 percent to listening.
We spend more time listening than we do in any other form of communication. However, most of
us don't pay much attention to it.
Research indicates that normal listening results in a 50percent retention immediately after a 10minute
presentation, which then declines to only about 25 percent after 48 hours. Extension Specialist Bob
Linda says the average person will hear 7. 5 minutes of a onehour presentation and will forget half of that.
One reason we listen so poorly is that our minds work much faster than our mouths. The average
person thinks 600-700 words per minute but speaks at a rate of about 125. His listeners' minds are
occupied with hearing only onefifth of the time he is speaking. The listeners may consider and react to
what is being said during the other fourfifths of the time, or become absorbed in coming up with his
response, or think other thoughts and miss the rest of what is being said.
If we really listen, we may be forced to accept a different perspective of reality. Most of us have
a firmly developed view of reality that we do not want to change. Carl Rogers, the psychiatrist, points
out that if you are really willing to listen to another, to enter his private world and see reality as he sees
it, you run the risk of being changed. "This risk of being changed is one of the most frightening prospects most of us can face. "
1. From the passage, we can learn that listening ______.
A. always forms a barrier to our communication
B. occupies the largest part in communication
C. will take the place of other ways of communication
D. is a difficult skill to master
2. The underlined word "retention" in the 3rd paragraph means "________".
A. attention
B. presentation
C. memory
D. occupation
3. In normal listening, the reason why an average person can only keep half of what the
speaker says in mind is that ________.
A. half of that will be forgotten
B. our mouths work much more slowly than our minds
C. most of us pay little attention to it
D. he is afraid of being changed
4. According to Carl Rogers, ________.
A. we should let listeners enter our private world
B. the opinions of the speakers may affect us if we listen to them willingly
C. we shouldn't make us changed while listening
D. it is wrong that we don't want to change while listening

The amount of water in the world is finite(有限的). The number of people is growing fast and water use is growing even faster. Global water consumption rose six times between 1900 and 1995—more than double the rate of population growth.
As important as quantity is quality—with pollution increasing in some areas，the amount of useable water declines.
And the wider effects of water shortages are just as frightening as the prospect of having too little to drink.
Seventy percent of the water used worldwide is used for agriculture. Much more will be needed if we are to feed the world's growing population. And consumption will rise further as more people expect Western－style lifestyles and diets—one kilogram of grain－fed beef needs at least 15 cubic metres of water，while a kilo of cereals(谷物)needs only up to three cubic metres.
New technology can help，however，especially by cleaning up pollution and so making more water useable，and in agriculture，where water use can be made far more efficient.
Drought－resistant(抗旱的)plants can also help.
The optimists say“virtual water”may save the day—the water contained in crops which could be exported from water－rich countries to dry ones. But the amounts involved would be huge，and the energy needed to transport the water would be enormous(巨大的).
In any case，it is not just us who need water，but every other species that shares the planet with us. We have to rethink how much water we really need if we are to learn how to share the earth's supply. While dams and other large－scale schemes play a big role worldwide，there is also a growing recognition of the value of using the water we already have more efficiently rather than harvesting ever more from our rivers. For millions of people around the world，getting it right is a matter of life and death.
1. Which of the following statements on water consumption is NOT true?
A. Agriculture consumes more than haft of the water used in the world.
B. The growing population worsens the water shortage situation.
C. Lifestyles play an important role in water consumption.
D. The Western way of agriculture uses more water than the Asian way.
2. “Virtual water” refers to the water that ________.
A. is hidden in crops
B. is saved in agriculture
C. can be transported
D. can be reused with the aid of the Internet
3. In the last paragraph，the author mainly ________.
A. criticizes big projects such as dams
B. criticizes the use of river water
C. calls for the protection of other species
D. calls for the more efficient use of water
4. What's the main idea of the text?
A. Water is mainly wasted in agriculture.
B. Water pollution is threatening our health.
C. Shortage of water is a very serious problem.
D. Population growing influences water use.
