{{B}}Old Man Myths and Realities{{/B}}1. When
does a middle-aged man become an old man? Officially, of course, it's when we
reach retirement age. But, as we all know, this is a fairly blunt (生硬的) method
of decision making. As life expectancy (预期寿命) increases, retirement planning
needs to be changed. This is because being an old man today is very different
from what it was a generation or so ago.2. Sixty-five is the new middle-aged
man. These days people are talking about the young-old, that is ages 70-75, and
those over 75 as the old-old. The young-old frequently continue in good health
and maintain strong links with friends and family. The old-old have a much
higher chance of poor health and social isolation.3. Although men are living
longer, there are still more old women than old men. This fact alone should
arouse interest as to why. Relatively little is actually known about why this is
the case or about the experiences of the old man. Sure, we are aware that the
old man experiences anxiety, financial problems, loneliness, etc., but that's
really about all we know.4. It is usually believed that the old man often
complains about their health. In fact, most rate their health as good even
though most are diagnosed with at least one chronic illness. The physical health
of the old man is strongly affected by their health behavior when they were
younger.
填空题Yoga May Help Ease High Blood Pressure
People who follow the ancient practice of yoga may be getting an added health boost, with a new study suggesting it can fight high blood pressure—also known as hypertension.
"This study confirms many people"s feelings that exercise may be useful in the control of hypertension," said Dr. Howard. "Yoga would be a useful adjunct in the lowering of blood pressure in certain populations."
1
Although the study couldn"t prove a cause-and-effect relationship, doing yoga two to three times a week was associated with an average drop in blood pressure readings from 133/80 to 130/77 ,the researchers said.
In comparison, the average decrease in blood pressure was smaller (134/83 to 132/82) among people who ate a special diet but did not do yoga. In a bit of a surprise, doing yoga in tandem with a special diet did not outperform doing yoga alone.
2
Dr. Howard said the study shows that "yoga can have a favorable effect" on hypertension.
3
"But some large population studies have suggested that changes of this magnitude could have very significant long-term benefits."
4
, including its relatively short length and the fact that most participants were young and had milder forms of high blood pressure, Dr. Howard said.
5
"Yoga, along with deep breathing exercises, meditation and inner reflection, is a good adjunctive and integrative cardiovascular approach to better health, including lowering blood pressure, as this data suggests," said Dr. David Friedman.
A. This may be because doing both required a greater amount of time, making it more difficult for participants to stick with their regimens.
B. In the study, researchers tracked 58 women and men, aged 38 to 62 ,for six months.
C. The study did have some limitations
D. Yoga is proved to be effective in lowering high blood pressure.
E. Another expert agreed that the ancient Indian practice of yoga might ease hypertension.
F. The amount of change was small, he said.

Shortly after the British naturalist, Charles Darwin,
published his theory of evolution, a Victorian lady was asked what she thought
of the idea that humans and animals were descended from a common ancestor. "Let
us hope it is not true," she said.{{U}} (46) {{/U}} This
story is probably apocryphal, but it illustrates well the attitudes of the
time.{{U}} (47) {{/U}}Many people accept Darwin's view of how we came
into being that our bodies evolved through the process of natural selection
acting on our genes. However, Darwin believed evolution was
responsible for far more than just our physical characteristics. He saw it as
the major influence in shaping our psychology. In- deed, he predicted that "in
the distant future, psychology will be based on a new foundation".{{U}} (48)
{{/U}} To proponents of concepts like free will and personal
responsibility, such an idea seems absurd.{{U}} (49) {{/U}} Their
research has revealed increasing evidence that the human mind is made up of
innate mechanisms, which control everything from the way we perceive time and
space, to how we learn survival techniques and choose mates. {{U}}
(50) {{/U}}Steven Pinker, Professor of Cognitive Science at the
Massachusetts Institute of Technology, likens language ability to computer
software, "children learn a new word every 90 minutes of their waking life for
years, then they have to figure out how to string them together using a kind of
mental computer program. The essence of human language is the ability to convey
new ideas by putting words together in different combinations. Since we all have
this language 'software' in our minds, we can figure out what others are saying
by the meanings of the words and the order in which they are
arranged." A. Today, we are more comfortable with out
past. B. "And, if it is true, let us hope it does not become
public knowledge." C. But a growing number of scientists are
questioning the extent to which our behavior is controlled by our
culture. D. Many people are calling for controls on cloning

was, of course, his theory of evolution. F. Nowhere is this more
obvious than our innate ability to learn languages.
填空题Lung Cancer
1 The death rate due to cancer of the lungs has increased more than 800 percent in males and has more than doubled in females during the last 25 years. It is considerably higher in urban and industrial areas than in rural districts. There are many possible causes, but it is still controversial which are most blameworthy. Those factors which have been mentioned most frequently are the presence of foreign particles and other irritants in the air (smoke particles, smog, exhaust fumes), and the smoking of cigarettes and cigars.
2 Numerous studies have demonstrated a striking correlation between the death rate from lung cancer and smoking habits. Among heavy smokers-21 to 30 cigarettes per day-the mortality rate from lung cancer is nearly 17 times the rate from nonsmokers. It is expected the death rate among women will increase as the present high rate of smoking among women has its effect.
3 Sometimes cases of lung cancer are discovered at the time an X-ray is taken for the purpose of detecting tuberculosis. Too often, however, a current emphasis upon the danger of exposure to radiation from X-ray machines can frighten people away from routine chest X-rays and thus prevent an early diagnosis of lung cancer. Early detection is absolutely essential if any possibility of cure is to be maintained. Modern X-ray machines in competent hands pose such slight danger, at least to those over 40 years of age, that this would be much more than offset by the advantages of discovering a tumor while it is small enough to be completely removed.
4 A common form of lung cancer is bronchogenic carcinoma, so-called because the malignancy originates in a bronchus. The tumor may grow until the bronchus is blocked, cutting off the supply of air to that lung. The lung then collapses, and the secretions trapped in the lung spaces become infected, with a resulting pneumonia or the formation of a lung abscess. Such a lung cancer can also spread to cause secondary growths in the lymph nodes of the chest and neck as well as in the brain and other parts of the body. The only treatment that offers a possibility of cure, before secondary growths have had time to form, is to remove the lung completely. This operation is called pneumonectomy.
5 Malignant tumors of the stomach, the breast, the prostate gland and other organs may spread to the lungs, causing secondary growths.
填空题China Seek Donors to Narrow Bone Marrow(骨髓)Gap
China has launched a campaign to recruit more bone marrow donors, amid a shortage of funds as well as of sibling donors who could help the growing number of patients in need of life-saving transplants, state media reported on Monday.
The Chinese Red Cross began the national campaign over the weekend to find donors for some 4 million patients suffering from leukaemia (白血病), thalassanemia (地中海贫血) and other blood diseases and awaiting bone marrow transplants, the official China Daily said. Every year China has 40,000 new leukaemia patients, most of them under 35 and 50 per cent of them children, the newspaper said. Other reports have linked China"s growing childhood leukaemia to solvents and building materials used in interior decoration.
With a tiny pool of bone marrow donors, weakened by the absence of sibling donors for most children because of China"s one-child policy, doctors rely on donors from Taiwan to save many young leukaemia patients, the Belling Evening News said last weekend. Tatwan, with a population of 22 million, has 210,000 registered donors compared with fewer than 30,000 donors among mainland China"s 1.3 billion people, the newspaper said.
Yet the lack of registered donors may reflect a lack of funding for testing and recording data on potential donors rather than a lack of volunteers, the newspaper said. China needs a pool of at least 100,000 donors but testing them would cost more than 50 million yuan (6 million dollars), it said.
The Hong Kong Marrow Match Foundation said it has helped "a handful" of patients in Beijing, Shanghai and other cities. "The number of requests is increasing" from mainland China, including direct calls to the charity from desperate patients or relatives, said the foundation"s donor coordinator Marven Chin. But the cost of extracting bone marrow from one of the foundation"s 40,000 registered donors and flying it by courier has to be borne by the patients, and many of them have to be aided financially, Chin said.
填空题The rate of forgetting is the same ______.
填空题Mergers The most common kind of consolidation today is the merger. A merger occurs (46) . With the deregulation of natural gas, the nation's 20 interstate pipeline companies became fearful of cutthroat competition. Some felt that they could increase their efficiency and improve their market flexibility by merging. In 1985 Inter north of Omaha paid $2.3 billion for Houston Natural Gas Corporation, (47) . The system connected markets from coast to coast and raised sales to $10 billion. On occasion, mergers have occurred between smaller companies in an industry dominated by a few giant firms. These smaller companies claim that they need to merge to become more efficient and effective in competing against the biggest corporations. They maintain that such action increases competition instead of reducing it. The Antitrust Division of the Justice Department has not always agreed with them. Four major waves of mergers have taken place in this country. The first started in 1887, just prior to the passage of the Sherman Antitrust Act, and ended in 1904. It involved such giants as United States Steel and Standard Oil trying to create monopolies in their industries. From the end of World War I until the 1930s, large firms swallowed smaller firms to create oligopolies. The monopoly had no chance and the oligopoly little chance of succeeding today under present antitrust policy. The third major merger movement began in the 1960s, reached a peak in 1969, (48) . Many of the acquisitions involved giant firms in one industry buying up large companies in totally unrelated industries. Such mergers are called conglomerate mergers. A classic example is Mobil Oil Corporation's purchase of the huge retail chain Montgomery Ward & Company. Mergers in the last ten years were in the thousands. More important is the value of the transactions, which has risen sharply. The number of mergers and acquisitions apply (49) . The petroleum industry had mergers and acquisitions valued at closed to $80 billion between 1981 and 1984. Other industries (50) were banking and finance, insurance, mining and mineral, processed foods.A. thereby gaining control of the world's longest pipelineB. and then gradually declinedC. experiencing large takeoversD. resulting in combinations of small firmsE. only to those valued at $100 million or moreF. when two or more companies get together to form one company
填空题
Einstein Named "Person of the
Century" Albert Einstein, whose theories on
space time and matter helped unravel the secrets of the atom and of the
universe, was chosen as "Person of the Century" by Time magazine on
Sunday. A man whose very name is synonymous with scientific
genius, Einstein has come to represent more than any other person the flowering
of 20th century scientific though that set the stage for the age of
technology. "The world has changed far more in the past 100
years than in any other century in history. The reason is not political or
economic, but technological—technologies that flowed directly from advances in
basic science," wrote theoretical physicist Stephen Hawking in a Time essay
explaining Einstein's significance. {{U}} {{U}} 1 {{/U}}
{{/U}} Time chose as runner-up President Franklin Roosevelt to
represent the triumph of freedom and democracy over fascism, and Mahatma Gandhi
as an icon for a century when civil and human rights became crucial factors in
global politics. "What we saw was Franklin Roosevelt embodying
the great theme of freedom's fight against totalitarianism, Gandhi personifying
the great theme of individuals struggling for their rights, and Einstein being
both a great genius and a great symbol of a scientific revolution that brought
with it amazing technological advances that helped expand the growth of freedom,
"said Time magazine Editor Walter Isaacson. Einstein was born
in Ulm, Germany in 1879. {{U}} {{U}} 2 {{/U}} {{/U}}He was slow
to learn to speak and did not do well in elementary school. He could not stomach
organized learning and loathed taking exams. In 1905, however,
he was to publish a theory which stands as one of the most intricate examples of
human imagination in history. {{U}} {{U}} 3 {{/U}}
{{/U}}Everything else—mass, weight, space, even time itself is a variable. And he
offered the world his now-famous equation: energy equals mass times the speed of
light squared-E=mc2. {{U}} {{U}} 4
{{/U}} {{/U}}"There was less faith in absolutes, not only of time and space
but also of truth and morality." Einstein's famous equation was
also the seed that led to the development of atomic energy and weapons. In
1939, six years after he fled European fascism and settled at Princeton
University, Einstein, an avowed pacifist, signed a letter to President Roosevelt
urging the United States to develop an atomic bomb before Nazi Germany did.
{{U}} {{U}} 5 {{/U}} {{/U}}Einstein did not work on the
project. Einstein died in Princeton, New Jersey in
1955. A. "Indirectly, relativity paved the way for a new
relativism in morality, art and politics," Isaacson wrote in an essay explaining
Time's choices. B. How he thought of the relativity theory
influenced the general public's view about Albert Einstein. C.
"Clearly, no scientist better represents those advances than Albert
Einstein." D. Roosevelt heeded the advice and formed the
"Manhattan Project" that secretly developed the first atomic weapon.
E. In his early years, Einstein did not show the promise of what he was
to become. F. In his Special Theory of Relativity, Einstein
described how the only constant in the universe is the speed of light.

{{B}}Dung to death{{/B}} Fields across
Europe are contaminated with dangerous levels of the antibiotics (抗生素) given to
farm animals. The drugs, which are in manure sprayed (喷射) onto fields as
fertilizers (肥料), could be getting into our food and water, helping to create a
new generation of antibiotic-resistant "superbugs” The warning
comes from a researcher in Switzerland who looked at levels of the drugs in farm
slurry.{{U}}(46) {{/U}} Some 20,000 tons of
antibiotics are used in the European Union and the US each year. More than half
are given to farm-animals to prevent disease and promote growth.{{U}} (47)
{{/U}} Most researchers assumed that humans become infected
with the resistant strains by eating contaminated meat. But far more of the
drugs end :up in manure than in meat products, says Stephen Mueller of the Swiss
Federal Institute for Environmental Science and Technology in Dubendorf.{{U}}
(48) {{/U}} With millions of tons of animals manure
(施肥于) spread onto fields of crops such as wheat and barley each year, this
pathway seems an equally likely route for spreading resistance, he said. The
drugs contaminate (污染) the crops, which are then eaten.{{U}} (49)
{{/U}} Mueller is particularly concerned about a group of
antibiotics called sulphonamides. {{U}}(50) {{/U}} His analysis found
that Swiss farm manure contains a high percentage of sulphonamides; each hectare
of field could be contaminated with up to 1 kilogram of the drugs. This
concentration is high enough to trigger the development of resistance among
bacteria. But vets are not treating the issue seriously. There
is growing concern at the extent to which drugs, including antibiotics, are
polluting the environment. Many drugs given to humans are also excreted
unchanged and are not broken down by conventional sewage (用污水灌溉)
treatment. A. They do not easily degrade or dissolve in
water. B. And manure contains especially high levels of bugs
that are resistant to antibiotics, he says. C. Animal
antibiotics is still an area to which insufficient attention has been
paid. D. But recent research has found a direct link between the
increased use of these farmyard drugs and the appearance of antibiotic-resistant
bugs that infect people. E. His findings are particularly
shocking because Switzerland is one of the few countries to have banned
antibiotics as growth promoters in animals feed. F. They could
also be leaching into tap water pumped from rocks beneath fertilized
fields.

Health Education Health
education is the part of health care that is concerned with promoting healthy
behavior. A person's behavior may be the main cause of a health problem, but it
can also be the main solution. This is true for the teenager
who smokes, the mother with the poorly nourished (营养) child, and the butcher
(屠夫,卖肉的人) who gets a cut on his finger. By changing their behavior these
individuals can solve and prevent many of their own problems.
Health education does not replace other health services, but it is needed
to promote the proper use of these services. One example of this is
immunization(免疫) : scientists have made many vaccines(疫苗) to prevent diseases,
but this achievement is of no value unless people go to receive immunization.
Health education encourages behavior that promotes health,
prevent illness, cures disease and contributes to recovery. The needs and
interests of individuals, families, groups, organizations, and communities are
at the heart of health education programs. Thus there are many opportunities for
practicing health education. Health education is not the same
thing as health information. Correct information is certainly a basic part of
health education, but health education must also address the other factors that
affect health behavior such as availability (可获性) of resources, effectiveness of
community leadership, social support from family members, and levels of
self-help skills. Health education therefore uses a variety of methods to help
people understand their own situations and choose actions that will improve
their health. Health education is incomplete unless it encourages involvement
and choice by the people themselves. Also, in health education
we do not blame people if they do not behave in a healthy way. Often unhealthy
behavior is not the fault of the individual. In health education we must work
with families, communities, and even regional authorities to make sure that
resources and support are available to enable each individual to lead a healthy
life.
A. Importance of immunization B. Relationship
with other health services C. Creation of necessary conditions
for healthy behavior D. Encouraging unhealthy behavior
E. Encouragement of behavior good for your health
F. Addressing a variety of behavior--affecting factors
填空题Insomnia
Chinese people don"t seem to be catching much sleep. Experts say insomnia (失眠) has become the second most serious health problem after headaches in neurological (神经病学的) diagnoses over the country, afflicting (使苦恼,折磨) most people between 30and 50.
According to a study last year on adult sleep quality in six large Chinese cities, about 57 percent of respondents have had sleep disorders over the year. And many of them have insomnia. Over the past four years, the number of patients treated at the insomnia clinic of the Sleep Disorders Institute at the Shanghai TCM Hospital has increased 3.5 times every year. Last year, it treated more than 18,000 people with sleeping problems, about 50 every day.
People complain to their doctors that when they cannot sleep well at night,they don"t feel good during the day. And then they can"t sleep well again that night. It"s a vicious cycle that haunts (visit frequently) people with sleep disorders.
Traditional Chinese Medicine (TCM) doctors are telling people to go to bed early in autumn and winter. Most Chinese believe it is a golden rule for good health. But new research indicates uninterrupted sleep is more important than the length of time in bed. Fragmented sleep causes health problems, which could affect the quality of sleep at night.
Different seasons make different times appropriate for going to bed and waking up, TCM doctors say. And in both autumn and winter, it"s better to sleep early and eat certain dishes to keep healthy. They suggest people at night to fall asleep between 11 p.m. and 1 a.m. and massage (按摩) the feet before sleeping if possible.
A new research in US indicates sleep does not change much from age 60 onwards; and poor sleep is not because of aging, but mostly because of illnesses or medications used to treat them, says a report in the
New York Times

填空题Every Dog Has Its Say
Kimiko Fukuda, a Japanese girl, always wondered what her dog was trying to say. Whenever she put on makeup, it would pull at her sleeve.
1
When the dog barks, she glances at a small electronic gadget (装置). The following "human" translation appears on its screen: "Please take me with you. I realized that"s how he was feeling." said Fukuda.
The gadget is called Bowlingual, and it translates dog barks into feelings. People laughed when the Japanese toymaker Takara Company made the world"s first dog—human translation machine in 2002 But 300,000 Japanese dog owners bought it.
2
"Nobody else had thought about it," said Masahiko Kajita, who works for Takara. "We spend so much time training dogs to understand our orders; what would it be like if we could understand dogs?" Bowlingual has two parts.
3
The translation is done in the gadget using a database (资料库) containing every kind of bark.
Based on animal behaviour research, these noises are divided into six categories, happiness, sadness, frustration, anger, declaration and desire
4
In this way, the database scientifically matches a bark to an emotion, which is then translated into one of 200 phrases.
When a visitor went to Fukuda"s house recently, the dog barked a loud "bow wow". This translated as "Don"t come this way".
5
The product will be available in US pet stores this summer for about US $120. It can store up to 100 barks, even recording the dog"s emotions when the owner is away.
A. A wireless microphone is attached to the dog"s collar, which sends information to the gadget held by the owner.
B. Nobody really knows how a dog feels.
C. It was followed by "I"m stronger than you" as the dog growled (嗥叫) and sniffed (嗅) at the visitor.
D. More customers are expected when the English version is launched this summer.
E. Now, the Japanese girl thinks she knows.
F. Each one of these emotions is then linked to a phrase like "Let"s play", "Look at me", or "Spend more time with me".

填空题Co-educational VS. Single-sex schools
Do you have any strong opinion on co-educational or single-sex schools?
A supporter of xo-educational schools would probably say that schools should be like the societies they belong to. In Hong Kong, men and women mix socially on a day-to-day basis. In many fields men are even likely to have female bosses. It is, therefore, desirable that boys and girls grow up together, go to school together, and prepare themselves for a society that does not value sexual separation.
Some would go on to argue further that growing up with members of the opposite sex is important for personal development. Regular contact (接触) can remove the strange ideas about the opposite sex and lead to more natural relationships. Single-sex conditions are seen as leading to more extreme opinions, and possibly even as encouraging homosexuality (同性恋), though there is no proof that this is the case.
Those who are against co-education often also fix their attention on the sexual side. Some parents fear that close contact with members of the opposite sex is dangerous for teenagers. They want their children to be attentive to their studies. Such parents feel uncomfortable with modern ways and the free mixing of the sexes.
A stronger argument comes from research into school results. Girls grow up earlier than boys, tend to be more orderly and are likely to be better at languages. In a mixed class, boys who might do well in a single-sex class become discouraged and take on the role of troublemaker. Certainly in the UK this situation has greatly alarmed (惊动) the government for it to be encouraging co-educational schools to have some single-sex classes. In the UK the best schools are all single-sex, strongly suggesting that co-education is not the best answer. This may, however, not be as simple as it looks. It may simply be that the famous old schools that attract the best students happen to be single-sex, rather than that being single-sex makes them better schools.
