填空题Reinventing the Table
An earth scientist has rejigged the periodic table to make chemistry simpler to teach to students.
1
But Bruce Railsback from the University of Georgia says he is the first to create a table that breaks with tradition and shows the ions of each element rather than just the elements themselves.
"I got tired of breaking my arms trying to explain the periodic table to earth students, " he says, criss-crossing his hands in the air and pointing to different bits of a traditional table.
2
But he has added contour lines to charge density, helping to explain which ions react with which.
"Geochemists just want an intuitive sense of what"s going on with the elements, " says Albert Galy from the University of Cambridge
3
4
He explains that sulphur, for example, shows up in three different spots one-for sulphide, which is found in minerals, one for sulphite, and one for sulphate, which is found in sea slat, for instance.
He has also included symbols to show which ions are nutrients, and which are common in soil or water.
5
A. There have been many attempts to redesign the periodic table since Dmitri Mendeleev drew it up in 1871.
B. Railsback has still ordered the elements according to the number of protons they have.
C. "I imagine this would be good for undergraduates. "
D. Railsback has listed some elements more than once.
E. And the size of element"s symbol reflects how much of it is found in the Earth"s crust.
F. The traditional periodic table was well drawn.
填空题A. imaginativelyB. recentlyC. carefullyD. unscientificallyE. accidentallyF. satisfactorily

Faces, like fingerprints, are unique. Did you ever wonder how
it is possible for us to recognize people? Even a skilled writer probably could
not describe all the features that make one face different from another. Yet a
very young child or even an animal, such as a pigeon--can learn to recognize
faces.{{U}} (46) {{/U}}. We also tell people apart by
how they behave. When we talk about someone's personality, we mean the ways in
which he or she acts, speaks, thinks and feels that individual different from
others. {{U}} (47) {{/U}}. But describing someone's
personality in words is somewhat easier than describing his face. If you were
asked to describe a "nice face" looked like, you probably would have a difficult
time doing so. But if you were asked to describe a "nice person", you might
begin to think about someone who was kind, considerate, friendly, warm, and so
forth. {{U}} (48) {{/U}}. Gordon Allport, an American
psychologist, found nearly 18,000 English words characterizing differences in
people's behavior. And many of us use this information as a basis for
describing, or typing, his personality. Bookworms, conservatives, military
types--people are described with such terms.{{U}} (49) {{/U}}. Actors in
early Greek drama wore masks to show the audience whether they played the
villain's (坏人)or the hero's role. In fact, the words "person" and "personality"
come from the Latin persona, meaning "mask".{{U}} (50) {{/U}}. But we
can easily tell the "good guys" from the "bad guys" because the two types differ
in appearance as well as in actions. A. There are many words to
describe how a person thinks feels and acts. B. Like the human
face, human personality is very complex. C. Today, most
television and movie actors do not wear masks. D. We recognize
a person by his or her appearance. E. We all take this ability
for granted. F. People have always tried to "type" each
other.
填空题
Leukemia is a kind of cancer in which abnormal white blood
cells grow in an uncontrolled manner. These abnormal cells interfere with the
production of normal white blood cells, which fight infection. Leukemia is a
disease of the bone marrow and other blood-forming organs. Consequently,
leukemia also affects the production of red blood cells, which carry oxygen from
the lungs throughout the body, and platelets, blood cells that help stop
bleeding. Signs of leukemia include repeated infection, anemia, and frequent
bleeding. 2. The cause of most human leukemia is
unknown. Researchers have discovered a leukemia virus in cats, and they have
identified a virus that appears to cause a rare type of leukemia in people.
Other possible causes include exposure to radiation and harmful chemicals.
3. Doctors classify leukemia according to the type
of white blood cell affected. Two of the main blood cell types affected by.
leukemia are myeloid and lymphoid. Myeloid cells fight bacterial infections.
Lymphoid cells detect and respond to the presence of foreign substances in the
body. All kinds of leukemia can be either acute of chronic. 4.
Acute leukemias often develop suddenly. Abnormal, immature white
blood cells multiply rapidly, and the number of normal cells decreases sharply.
Acute myeloid leukemia most often occurs among adults. The treatment for this
leukemia is chemotherapy, the use of chemicals that are more toxic to cancer
cells than to normal cells. Seventy percent of patients enter remission. During
remission, the blood cells and the bone marrow temporarily return to normal.
Researchers are trying to develop methods of prolonging remission in acute
myeloid leukemia patients. The treatment of acute leukemias is intensive and may
endanger the patient's life. The use of powerful antibiotics and of blood
transfusions has increased the chances of surviving the intensive therapy.
5. Chronic leukemias develop more slowly
than acute leukemias. In chronic leukemias, the abnormal white blood cells
appear mature, and they resemble normal white blood cells. In the early stages
of the disease, these abnormal cells even function normally to some extent.
Chronic lymphocytic leukemia is the most common leukemia among adults. The
average age of people suffering from this disease is the early 70's. The disease
may take as long as 10 years to develop completely. Chronic myeloid leukemia is
a less common form of leukemia that occurs primarily among adults. Doctors
generally use drugs to treat chronic leukemia patients.
填空题Intellectual Disability
People with intellectual disability form one of the largest single disability groups in a community. Intellectual disability refers to a general slowness to learn and function within society, and the identification of intellectual disability is usually based on an assessment of a person"s performance in a variety of tests. An individual"s level of performance, as assessed, can change with time and circumstances. With skilled training and opportunity for development, people with intellectual disability have much greater potential for acquiring skills and for participation in community life than previously had been thought possible.
In many western societies, five categories of intellectual disability have traditionally been used in order to indicate the perceived degree of difficulty an individual has with learning. All five may occur in either children, adolescent or adult, and show as mild, moderate, severe, profound or multiple intellectual disability.
For the majority of intellectual disabilities, there is no identifiable cause but there are some causes that are well documented. They include: brain damage at birth due to lack of oxygen—prolonged labor during childbirth; brain damage before birth due to factors such as rubella (风疹), drug or diet-related problems; damage after birth due to illnesses such as encephalitis (脑膜炎) or accident; hereditary defects in the genes;abnormal chromosome count resulting in, for example, Down Syndrome (唐氏综合症).
Like everyone else, people with an intellectual disability need a rewarding job, a satisfying place to live and a good social life. But they may need extra support to achieve these things. Good support services are based on the principle of normalization—which means enabling people to be part of the community like everyone else.
With the introduction of the intellectually disabled into communities, there is a need to promote awareness of communication. Although many people may have little experience in talking with an intellectually disabled person, there are common guidelines that can simplify the interaction. Firstly, it is useful to remember that people with disabilities have feelings. Speaking in the same friendly manner as you would to anyone else is also recommended. Being prepared to wait a little longer for replies during a conversation with an intellectually disabled person would undoubtedly benefit the exchange.

填空题Mergers The most common kind of consolidation today is the merger. (46) With the deregulation of natural gas, the nation's 20 interstate pipeline companies became fearful of cutthroat competition. (47) In 1985 Internorth of Omaha paid $2.3 billion for Houston Natural Gas Corporation, thereby gaining control of the world's longest pipeline. 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. (48) 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 has 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,and then gradually declined. Many of the acquisitions involved giant firms in one industry buying up large companies in totally unrelated industries. Such mergers are called conglomerate mergers (49) 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 only to those valued at $100 million or more. The petroleum industry had mergers and acquisitions valued at close to $ 80 billion between 1981 and 1984. (50) A. Some felt that they could increase their efficiency and improve their market flexibility by merging.B. They maintain that such action increases competition instead of reducing it.C. Other industries experiencing large takeovers were banking and finance, insurance, mining and mineral, and processed foods.D. Fierce competition on the international market results in combinations of small firms.E. A classic example is Mobil Oil Corporation's purchase of the huge retail chain Montgomery Ward & Company.F. A merger occurs when two or more companies get together to form one company.
填空题The Drink Your Body Needs Most
1. Our bodies are estimated to be about 60 to 70% water. Blood is mostly water, and our muscles, lungs, and brain all contain a lot of water. Water is needed to regulate body temperature and to provide the means for nutrients (滋养物) to travel to all our organs. Water also transports oxygen to our cells, removes waste, and protects our joints and organs.
2. We lose water through urination (排尿), respiration (呼吸), and by sweating. If you are very active, you lose more water than if you do not take much exercise. Symptoms of mild dehydration (脱水) include chronic pains in joints and muscles, lower back pain, headaches, and constipation (便秘). A strong smell to your urine, along with a yellow color indicates that you are not getting enough water. Thirst is an obvious sign of dehydration and in fact, you need water long before you feel thirsty.
3. A good rule of thumb (好的做法) is to take your body weight in pounds and divide that number in half. That gives you the number of ounces (盎司) of water per day that you need. For example, if you weigh 160 pounds, you should drink at least 80 ounces of water per day. If you exercise you should drink another 8-ounce glass of water for every 20 minutes you are active. If you drink coffee or alcohol, you should add at least an equal amount of water. When you are traveling on an airplane, it is good to have 8 ounces of water for every hour you are on board the plane.
4. It may be difficult to drink enough water on a busy day. Be sure you have water handy at all times by keeping a bottle for water with you when you are working, traveling, or exercising. If you get bored with plain water, add a bit of lemon for a touch of flavor. There are some brands of flavored water available, but some of them have sugar or artificial sweeteners that you don"t need.
填空题Bedwetting (尿床)
Millions of kids and teenagers from every part of the world wet the bed every single night. It"s so common that there are probably other kids in your class who do it. Most kids don"t tell their friends, so it"s easy to feel kind of alone, like you might be the only one on the whole planet who wets the bed.
1
The fancy name for bedwetting is nocturnal enuresis. Enuresis runs in families. This means that if you urinate, or pee, while you are asleep, there"s a good chance that a close relative also did it when he or she was a kid.
2
The most important thing to remember is that no one wets the bed on purpose. It doesn"t mean that you"re lazy or a slob.
3
For some reason, kids who wet the bed are not able to feel that their bladders is full and don"t wake up to pee in the toilet. Sometimes a kid who wets the bed will have a realistic dream that he"s in the bathroom peeing only to wake up later and discover he"s all wet. Many kids who wet the bed are very deep sleepers.
4
Some kids who wet the bed do it every single night. Others wet some nights and are dry on others. A lot of kids say that they seem to be drier when they sleep at a friend"s or a relative"s house.
5
So the brain may be thinking, "Hey, you! Don"t wet someone else"s bed! " This can help you stay dry if you"re not aware of it.
A. The good news is that almost all kids who wet the bed eventually stop.
B. Trying to wake up someone who wets the bed is often like trying to wake a log— they just stay asleep.
C. It"s something you can"t help doing.
D. Just like you may have inherited your mom"s blue eyes or your uncles" long legs, you probably inherited bedwetting, too.
E. That"s because kids who are anxious about wetting the bed may not sleep much or only very lightly.
F. But you are not alone.
填空题Before you fall in love, you'd better get a job As told by Lee Joon-ho, 20, a senior in law at Seoul National University, Korean TV dramas have shown a lot of rebellious youth, (46) . Confucianism has a great influence on us. For instance, Confucius said that we should be dutiful to our parents and value the family. Thus we prefer a school that's close to home so we can go back every day. (47) . The other day, my professor was flying to Vienna on a business trip. Instead of waiting for hours in the queue, he was told to check in first and didn't have any problem with overweight luggage. When it comes to important decision-making, such as choosing a university, a job, and a wife, we listen to our parents' suggestions. Most parents seem liberal in study decisions, (48) . Male chauvinism (大男子主义) is prevalent among our parents' generation, since they had to support the whole family through hard work. We need to shoulder the same responsibility, but we've also learned to respect women, as they're doing prominent work in lots of areas. (49) .

Many Benefits from Cancer
Organization 1 Do you know a child who
survived leukemia (白血病) ? Do you have a mother, sister or aunt whose breast
cancer was found early thanks to a mammogram (乳腺X光照片) ? Do you have a friend or
coworker who quit smoking to reduce their risk of lung cancer? Each of these
individuals benefited from the American Cancer Society's research program.
2 Each day scientists supported by the American Cancer
Society work to find breakthroughs that will take US one step closer to a cure.
The American Cancer Society has long recognized that re search holds the
ultimate answers to the prevention, diagnosis and treatment of cancer.
3 As the largest source of nonprofit cancer research
funds in the United States, the American Cancer Society devotes over $100
million each year to research. Since 1946, they've invested more than $ 2.4
billion, in research. The investment has paid rich dividends(回报、效益). In 1946
,only one in four cancer patients was alive five years after diagnosis;today 60
percent live longer than five years. 4 Investigators and
health professionals in universities, research institutes and hospitals
throughout the country receive grants from the American Cancer Society. Of the
more than 1,300 new applications received each year, only 11 percent can be
funded. If the American Cancer Society had more money available for research
funding, nearly 200 more applications considered outstanding could be funded
each year? 5 You can help fund more of these applications
by participating in the American Cancer Society Relay(拉力) for Life, a team event
to fight cancer. More funding means more cancer break throughs and more lives
being saved. To learn more, call Donna Hood, chair with the Neosho Relay for

填空题The Earth is surrounded by an ocean of gases we call the atmosphere. The atmosphere is important because it contains the air most living things breathe. ______ It even recycles water by returning it back to the Earth as rain. Without the atmosphere, life as we know it could not exist on Earth. The atmosphere extends about 600 kilometers (about 373 miles) above the surface of the Earth. Scientists discovered that the atmosphere is divided into layers, just like a layer cake.A. The layer of the atmosphere we live in is called the Troposphere (对流层).B. It also absorbs heat energy from the sun.C. Air temperature and air pressure are not the same all the way up through the Troposphere.D. Together they make up the remaining half of all the air that surrounds the Earth.E. Scientists have discovered that the ozone layer has gotten thinner due to pollution.F. It is also wise to wear sunglasses on bright days to guard against damage to our eyes.
填空题Archaeological Archaeological study covers an extremely long span of time and a great variety of subjects. The earliest subjects of archaeolgical study date from the origins of humanity. These include fossil remains believed to be of human ancestors who lived 3.5 million to 4.5 million years ago. The earliest archaeological sites include those in Ethiopia, Tanzania, Kenye; and elsewhere in East Africa. These sites contain evidence of the first appearance of bipedal(upright-walking),apelike early humans. (46) Some sites also contain evidence of the earliest use of simple tools. Asia about 1.8 million years ago, then into Europe about 900,000 years ago. The first physically modern humans, Homo sapiens, appeared in tropical Africa between 200,000and 150,000 years ago dates determined by molecular biologists and archaeologists working together. Dozens of archaeological sites through tout Age(100,000 to 15,000 years ago). (47) Archaeologists have documented that the development of agriculture took place about 10,000 years ago. Early domesticationis evident in such places as the ancient settlement in Jordan and in Mexico. Archaeology plays a major role in the study of early civilizations, such as those of the Sumerians of Mesopotamia, who built the city of Ur, and the ancient Egyptians, who are famous for the pyramids near the city of Gina and the royal sepulchers(tombs)of the Valley of the Kings at Thebes. (48) Archaeological research spans the entire development of phenomena that are nuique to hu mans. For instance, archaeology tells the story of when people learned to bury their dead and developed beliefs in an afterlife. Sites containig signs of the first simple but purposeful burials in graves date to as early as 40,000 years ago in Europe and Southwest Asia. By the time people lived in civilizations, burials and funeral ceremonies had become extremely important and elaborate rituals. (49) . Few burials rival their lavish sepulchres. Being able to trace the development of such rituals over thousands of years has added to our understanding of the development of human intellect and spirit. Archaeology also examines more recent historical periods. Some archaeologists work with historians to study American colonial life, for example. They have learned such diverse information as how the earliest colonial settlers in Jamestown, Virginia, traded glass beads for food with native Algonquian peoples; how the lives of slaves on plantations reflected their roots in Africa; and how the first major cities in the United States developed. (50) . This garbage is the modern equivalent of the remains found in the archaeological record. In the future, archaeologists will continue to move into new realms of study.[A] For example, the Mocha lords of Sip an in coastal Peru were buried in about ad 400 in fine cotton dress and with exquisite ornaments of bead, gold, and silver.[B] By 40,000 yeas ago people could be found hunting and gathering food across most of the regions of Africa.[C] Archaeological studies have also provided much information about the people who first arrived in the Americas over 12,000 years ago.[D] They were simple plants that had not devloped sepa-appeared in the Silurian period. They were simple plants that had not developed separate stems and leaves.[E] One site in Tanzania even reveals footprints of humans from 3.6 million years ago.[F] One research project involves the study of garbage in present-day cities across the United States.[G] Other sites that represent great human achievement are as varied as the cliff dwellings of of the ancient Anasazi(a group of early Native Americans of North America)at Mesa Verde, Colorado; the Inca city of Machu Picchu high in the Andes Mountains of Peru; and the mysterious, massive stone portrait heads of remote Easter I sand in the Pacific.
填空题The Safeness of IUDs for HIV-positive Women 1. Women infected with the most common form of HIV may safely use the intrauterine device (IUD) for contraception, provided they see a doctor regularly, new study findings suggest. 2. World Health Organization guidelines currently state that, in general, HIV-infected women should avoid IUDs. "Those guidelines were essentially made on theoretical concerns, and there are really very little data on what contraceptive is appropriate for HIV-infected women, " said the lead author Dr. Charles S. Morrison in North Carolina. 3. Morrison and colleagues gathered information on IUD-related complications at 1,4 and 24 months after placement of the device in 636 women living in Nairobi, Kenya. Of these women, 156 had HIV infection. Participating physicians did not know the patients' HIV status. There was "little difference in any side effects in HIV-infected women compared with HIV-uninfected women, suggesting that the IUD is likely an appropriate method for HIV-infected women, " Morrison said. "This is an important issue, because there are now 16 million women living with HIV and a lot of them have a critical need for contraception, " he added. 4. The researchers did find that women with infections such as gonorrhea or chlamydia at the study's outset were at increased risk of IUD complications, confirming current guidelines suggesting that women with sexually transmitted diseases not use IUDs. 5. In addition, there was no difference in the amount of virus the HIV-positive women were releasing from their cervix, or shedding, at the beginning of the study compared with 4 months after the IUD was inserted, the researchers reported in the August issue of the British Journal of Obstetrics and Gynaecology. Conversely, some studies have shown a relationship between increased cervical HIV shedding and the use of oral contraceptives. 6. "What this study suggests is that you need to avoid IUD use in women with a cervical infection but not women with HIV infection, " Morrison said. "Women with cervical infections are at increased risk of complications; women with HIV infection are not. /
填空题False Fear of Big Fish
Many people believe sharks (鲨鱼) are dangerous and will always try to hurt or even kill humans.
26
A shark exhibition at the National Aquarium (水族馆) in Baltimore, US, proves this. Visitors can touch young sharks, see their eggs develop and watch a dozen different species swim smoothly around a huge tank.
Most people fail to realize that shark attacks don"t happen very often. Humans are more likely to be killed by lightning than by a shark.
27
There, kids can learn, from an early age, not to fear sharks.
"People fear what they don"t know," said Nancy Hotchkiss, an organizer of the exhibition. "Sharks have been around for 400 million years and play an important role in the ocean"s food chain. We want people to discover that sharks are amazing animals that need our respect and protection. "
28
A study, published in January in the US magazine,
Science
, found that almost all recorded shark species have fallen by half in the past eight to fifteen years. Thousands of sharks are hunted in Asia for special foods, such as shark fin (鱼翅) soup. And many others get caught in nets, while fishermen are hunting other fish.
29
"Some fishing methods are actually cleaning out the ocean for sharks," said Dave Schofield, the manager of the aquarium"s ocean health programme.
30
A. They can watch them develop inside their eggs and feed the skin of the older swimmers.
B. A shocking 100 million sharks are killed every year around the world by humans.
C. In fact, 94 per cent of the world"s 400 species are harmless to humans.
D. It is a worrying situation and some areas have put measures in place to protect these special fish.
E. And to make this point clear, the museum has set up a special touching pool for children.
F. More than half of the sharks caught are smaller than one metre long.

1. Forty-thousand of the world's young children die every day. This is
15-million a year. Many of these deaths can be prevented. In fact, experts say
techniques now exist to save the lives of half of these children. The techniques
are medically effective, simple to use and low cost. The biggest task has been
to inform parents about these life-saving techniques. 2. The
Untied Nations Children's Fund, UNICEF, list four ways to improve children's
health. The first way is to use a mixture of sugar, salt and water to treat
diarrhea (腹泻). The second way is to use vaccines(疫苗)to protect children against
common diseases. The third way is to feed babies mother's milk. And the fourth
way is to measure carefully children's growth rates. 3. Diarrhea
is the major cause of death among children in developing countries. Diarrhea
results when the body tries to clear itself of harmful bacteria. The body does
this by forcing fluids out, sometimes uncontrollably, from the bowels(肠). If too
much water, sugar and salt are lost in this way, the kidneys(肾)and heart
cannot work normally, The child may die. 4. UNICEF's diarrhea
treatment is called Oral Rehydration Therapy. It uses a simple mixture of sugar
and salt in water. The mixture does not stop diarrhea. But if used as often as
needed, it keeps fluid levels normal until the body has fought off the harmful
bacteria.
填空题Hypnosis(催眠)
Increasing numbers of American doctors are using a technique known as hypnosis. They say hypnosis often can help persons stop suffering pain and stress. It also can help speed the healing of burns, and treats some forms of asthma and some skin diseases. Hypnosis is not new. It has been used for many years both in scientific research and to please crowds at public gatherings.
Hypnosis is commonly described as a condition similar to sleep. But,experts say it is more a form of sleep, in which the thought becomes so intense that it is no longer just a thought. To the person, it becomes reality.
Hypnotized patients are reported to have increased self-control and a reduced sense of pain. Some doctors use hypnosis to limit pain during a medical operation. Hypnosis is used mainly when the patient may have problems with usual anesthetic or pain-killing drugs. Doctors may advise hypnosis for women who are giving birth. Dentists may use it in place of traditional pain-killing drugs, such as novocaine. Hypnosis also has been used to treat burn victims. Researchers have found that burn victims who are hypnotized improve faster than those who are not. But, they are not sure why this happens.
Hypnosis can reduce or end a patient"s pain. But experts say this does not mean the patient is cured. The problem that caused the pain still must be treated.
Experts also say persons cannot be forced to do something they would normally oppose. That is why hypnosis often is not effective in treating cigarette smokers and persons who eat or drink too much. The success of the technique depends on how much someone wants it to succeed.
