Eat to Live
A meager diet may give you health and long life, but it’s not much fun — and it might not even be necessary. We may be able to hang on to most of that youthful vigor even if we don’t start to diet until old age. Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse’s liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won’t reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins.
Spindler’s team fed three mice a normal diet for their whole lives, and fed another three on half-rations3. Three more mice were switched from the normal diet to half-feed3 for a month when they were 34 months old — equivalent to about 70 human years.
The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production一probably bad news for mouse health. In the mice that had dieted all their lives,27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 per cent of these gene changes.
"This is the first indication that these effects kick in pretty quickly,”says Huber Warner from the National Institute on Aging near Washington D. C.
No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful. “There’s attracting and tempting evidence out there that it will work,” he says.
If it does work in people,there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective.
But Spindler isn’t sure the trade-off is worth it. “The mice get less disease, the y live longer, but they’re hungry,” he says. “Even seeing what a diet does, it’s still hard to go to a restaurant and say: ‘I can only eat half of that,. ”
Spindler hopes we soon won’t need to diet at all. His company, Lifespan Genetics in California, is looking for drugs that have the effects of calorie restriction.

第二十九篇“Don’t Drink Alone” Gets New Meaning
In what may be bad news for bars and pubs，a European research group has found that people drinking alcohol outside of meals have a significantly higher risk of cancer in the mouth and neck than do those taking their libations with food. Luigino Dal Maso and his colleagues studied the drinking patterns of 1,500 patients from four cancer studies2 and another 3，500 adults who had never had cancer.
After the researchers accounted for the amount of alcohol consumed, they found that individuals who downed a significant share of their alcohol outside of meals3 faced at least a 50 to 80 percent risk of cancer in the oral cavity, pharynx, and esophagus, when compared with people who drank only at meals. Consuming alcohol without food also increased by at least 20 percent the likelihood of laryngeal4 cancer. “ Roughly 95 percent of cancers at these four sites5 traced to smoking or drinking6 by the study volunteers，”Dal Maso says. The discouraging news, his team reports, is that drinking with meals didn’t eliminate cancer risk at any of the sites.
For their new analysis，the European scientists divided people in the study into four groups，based on how many drinks they reported having in an average week7. The lowest-intake group included people who averaged up to8 20 drinks 狂week. The highest group reported downing at least 56 servings of alcohol weekly for an average of eight or more per day.9 Cancer risks for the mouth and neck sites rose steadily with consumption even for people who reported drinking only with
meals. For instance, compared with people in the lowest-consumption group, participants who drank 21 to 34 alcohol servings a week at least doubled their cancer risk for all sites other than the larynx10. If people in these consumption groups took some of those drinks outside meals, those in the higher consumption group at least quadrupled their risk for oral cavity and esophageal cancers.
People in the highest-consumption group who drank only with meals had 10 times the risk of oral cancer, 7 times the risk of pharyngeal cancer, and 16 times the risk of esophageal cancer compared with those who averaged 20 or fewer drinks a week with meals. In contrast, laryngeal cancer risk in the high-intake, with-meals-only group11 was only triple that12 in the low-intake consumers who drank with meals. “Alcohol can inflame tissues. Over time, that inflammation can trigger cancer. ”Dal Maso says. He suspects that food reduced cancer risk either by partially coating digestive-tract tissues or by scrubbing alcohol off those tissues. He speculates that the reason laryngeal risks were dramatically lower for all study participants traces to the tissue’s lower exposure to alcohol.
1. Researchers have found that the risk of cancer in the mouth and neck is higher with people
A who drink alcohol outside of mealsur
2. Which of the following is NOT the conclusion made by the researchers about “drinking with meals”?
C It increases by 20 percent the possibility of cancer in all sites.
3. Approximately how many drinks do the lowest-intake group average per day?
A 3 drinks.
4. Which cancer risk is the lowest among all the four kinds of cancer mentioned in the passage?
B Laryngeal cancer.
5. According to the last paragraph, tissue’s lower exposure to alcohol
D reduces the risk of laryngeal cancer.
第三十九篇Sauna
Ceremonial bathing has existed for thousands of years and has many forms, one of which is the sauna. The Finns have perfected the steam bath，or sauna, which may be taken, usually in an enclosed room, by pouring water over hot rocks or as a dry heat bath. The Japanese, Greeks, Turks and Russians as well as Native Americans have forms of the sweat bath in their bathing rituals. Dry heat and steam baths had advocates in ancient Rome and' pre-Columbian Americans used sweat lodges.
The earliest saunas were probably underground caves heated by a fire
that naturally filled with smoke as chimney making was unknown at that time. A fire kept in a fire-pit would heat the rock walls of the cave. After reaching full heat, the smoke was let out of the cave and the stones would retain heat for several hours. A few people today say that the smoke sauna, “ savusauna”，is the only true sauna experience and that all saunas should have at least a background odor or smoke. Today most saunas use electric stoves, although gas and wood-burning stoves are available.
Saunas are relaxing and stress relieving, Those with muscle aches or arthritis may find that the heat relaxes muscles and relieves pain and inflammation. Asthma patients find that the heat enlarges air passageways of the lung and facilitates breathing. Saunas do not cure the common cold but they may help to alleviate congestion arid speed recovery time. The body’s core temperature usually rises a 1-2 degrees while in the sauna, thus imitating a slight fever. The sauna could be considered to fol low the old saying “feed a cold，starve a fever' The regular use of a sauna may decrease the likelihood of getting a cold in the first place.
Sauna is good for your skin as the blood flow to the skin increases and sweating occurs. Adults sweat about 2 lbs8 of water per hour on average in a sauna. A good sweat removes dirt and grime from pores and gives the skin a healthy glow. The loss in water weight is temporary as the body's physiological mechanisms will quickly restore proper volumes. The cardiovascular system9 gets a work out10 as the heart must pump harder and faster to move blood to the surface for heat exchange. Heart rate may increase from 72 beats per minute on average to 100-150 beats per minute.
A normal heart can handle these stresses but those with heart trouble wishing to begin to use a sauna should seek a doctor's advice. The elderly and those with diabetes should check with their doctor prior to beginning to take saunas. Pregnant women should not take saunas, particularly in the first three months. Indeed, everyone just starting out should take short sessions11 at first to become accustomed to this type of bath.
1. Ceremonial bathing _________.
C) has various forms
2. What is understood by some people to be the true sauna experience?
B) Saunas with smoke.
3. According to the third paragraph, saunas can do all of the following EXCEPT .
D) curing asthma
4. According to the fourth paragraph, sauna gives the skin a healthy glow because_________.
A) pores are cleaned by sweat
5. Who are advised not to take a sauna?
D) All of the above.
第二篇 A Biological Clock
Every living thing has what scientists call a biological clock that controls behavior. The biological clock tells _ plants when to form flowers and when the flowers should open. It tells _ insects _ when to leave the protective cocoons and fly away，and it tells animals and human beings when to eat, sleep and wake.
Events outside the plant and animal _ affect the actions of some biological clocks. Scientists recently found, for example, that a tiny animal changes the color of its fur _ because of _ the number of hours of daylight. In the short _ days _ of winter, its fur becomes white. The fur becomes gray brown in color in the longer hours of daylight in summer.
Inner signals control other biological clocks. German scientists found that some kind of internal clock seems to order birds to begin their long migration _ flight _ twice each year. Birds _ prevented from _ flying become restless when it is time for the trip，_ but _ they become calm again when the time of the flight has ended.
Scientists say they are beginning to learn which _ parts _ of the brain contain biological clocks. An American researcher, Martin Moorhead, said a small group of cells near the front of the brain _ seems to control the timing of some of our actions. These _ cells _ tell a person when to _ awaken _ ，when to sleep and when to seek food . Scientists say there probably are other biological clock cells that control other body activities.
Dr. Moorhead is studying _ how _ our biological clocks affect the way we do our work. For example, most of us have great difficulty if we must often change to different work hours.
_ It _ can take many days for a human body to accept the major change in work hours. Dr. Moorhead said industrial officials should have a better understanding of biological clocks and how they affect workers. He said _ such _ understanding could cut sickness and accidents at work and would help increase a factory’s production,
第九篇The Case of the Disappearing Fingerprints
One useful anti-cancer drug can effectively erase the whorls and other characteristic marks that give people their distinctive fingerprints. Losing _ them._ could become troublesome. A case
released online in a letter by Annals of Oncology indicates how big a _ problem _ of losing fingerprints is.
Eng-Huat Tan, a Singapore-based medical doctor describes a 62-year old man who has used capecitabine to _ treat._ his nasopharyngeal cancer. After three years on the _ drug. ，the patient decided to visit U. S. relatives last December. But he was stopped by U. S. customs officials _ for 4 hours after entering the country when those officials couldn't get fingerprints from the man. There were no distinctive swirly _ marks _ appearing from his index finger.
U. S. customs has been fingerprinting incoming foreign visitors for years, Tan says. Their index fingers are printed _ and screened against digital files of the fingerprints of bad guys—terrorists and potential criminals that our federal guardians have been tasked with keeping out of the country. Unfortunately, for the Singaporean traveler，one potential _ side _ effect of his drug treatment is a smoothing of the tissue on the finger pads. _ Hence _ ，no fingerprints.
“It is uncertain when fingerprint loss will _ begin _ to take place in patients who are taking capecitabine，” Tan points out. So he cautions any physicians who _ prescribe _ the drug to provide their patients with .a doctor’s note pointing out that their medicine may cause fingerprints to disappear.
Eventually, the Singapore traveler made it into the United States. I guess the name on his passport didn’t raise any red flags. But he，s also now got the explanatory doctor’s note —and won’t leave home _ without _ it.
By the way, maybe the Food and Drug Administration, _ which _ approved use of the drug
11 years ago, should consider _ updating _ its list of side effects associated with this medicine. The current list does note that patients may experience vomiting, stomach pain and some other side effects. But no where _ does _ it mention the potential for loss of fingerprints.
第十四篇Young Adults Who Exercise Get Higher IQ Scores Young adults who are fit have a higher IQ and are more _ likely _ to go on to university，reveals a major new study carried out at the Sahlgrenska Academy and Sahlgrenska University Hospital.
The results were recently published in the Proceedings of the National Academy of Sciences (PNAS). The study involved 1.2 million Swedish
men doing military service who were born between 1950 and 1976. The research group analyzed the _ results _ of both physical and IQ tests the youngsters took right after they started serving the army.
The study shows a clear link _ between _ good physical fitness and
better results for the
IQ test.
The
strongest
links are for _ logical
_
thinking and verbal comprehension. But it is only fitness that plays a
role _ in the results for the IQ test，and not strength. “Being fit means
that you also have good heart and lung _ capacity _ and that your brain
gets plenty of oxygen _ ，”says Michael Nilsson, professor at the
Sahlgrenska Academy and chief physician at the Sahlgrenska
University Hospital. “This may be one of the reasons why _ we can see
a clear link with fitness, but not with muscular strength _. We are also
seeing that there are growth factors that are important. ”
By analyzing data for twins, the researchers have been able _ to
determine that it is primarily environmental factors and not genes that
explain the link between fitness and a _ higher _ IQ.
“We have also shown that those youngsters who _ improve _ their
physical fitness between the ages of 15 and 18 increase their cognitive
performance,” says Maria Aberg, researcher at the Sahlgrenska
Academy and physician at Aby health centre. “This being th e case6,
physical _ education _ is a subject that has an important place in schools,
and is an absolute must if we want to do well in maths and other
theoretical subjects.”
The researchers have also compared the results from fitness tests _
during _ national service with the socio-economic status of the men
later in _ life _. Those who were fit at 18 were more likely to go into
higher education, and many secured more qualified jobs.

理工C阅读理解新增文章 第九篇An Essential Scientific Process All life on the earth depends upon green plants. Using sunlight, the plants produce their own food. Then animals feed upon the plants. They take in the nutrients the plants have made and stored. But that’s not all. Sunlight also helps a plant produce oxygen. Some of the oxygen is used by the plant, but a plant usually produces more oxygen than it uses. The excess oxygen is necessary for animals and other organisms to live. The process of changing light into food and oxygen is called photosynthesis. Besides light energy from the sun, plants also use water and carbon dioxide. The water gets to the plant through its roots. The carbon dioxide enters the leaves through tiny openings called stomata. The carbon dioxide travels to chloroplasts, special cells in the bodies of green plants. This is where photosynthesis takes place. Chloroplasts contain the chlorophylls that give plants their green color. The chlorophylls are the molecules that trap light energy. The trapped light energy changes water and carbon dioxide to produce oxygen and a simple sugar called glucose. Carbon dioxide and oxygen move into and out of the stomata. Water vapor also moves out of the stomata. More than 90 percent of water a plant takes in through its roots escapes through the stomata. During the daytime, the stomata of most plants are open. This allows carbon dioxide to enter the leaves for photosynthesis. As night falls, carbon dioxide is not needed. The stomata of most plants close. Water loss stops. If photosynthesis ceased, there would be little food or other organic matter on the earth. Most organisms would disappear. The earth’s atmosphere would no longer contain oxygen. Photosynthesis is essential for life on our planet. 词汇： nutrient n.营养物 organism n.生物体，有机体 carbon dioxide n.二氧化碳 chloroplast n.叶绿体 molecule n.分子 vapor n.水蒸气 oxygen n.氧气 photosynthesis n.光合作用 chlorophyll n.叶绿素 glucose n.葡萄糖 cease v.停止 注释： 1．Then animals feed upon the plants.动物以植物为食。 练习： 1．In the first paragraph，the word “excess” means Aheavy.

2020年职称英语考试卫生类B级阅读判断练习及答案 （3） “We hire talent. ” Those are the words of Rod Franz， a civil service computer technology director， responding to the question of opportunities for women who are interested in pursuing careers as computer technicians. On at least one of three shifts in his operation， the male-female ratio is 50-50. That is not surprising because government and educational institutes are required by the law to make every effort to open hiring opportunities to women and minority workers. What may be even more interesting to young women is that，according to Franz， private industry is hiring women and minorities away from us. And， since private industry pays more， it succeeds. Managers in the rapidly growing computer service field are quick to agree. They strongly encourage women to train for technician jobs， and they actively recruit female technicians across the country. They believe that this career field offers a wealth of possibility for women. A recent study by the Devry Institute of Technology that involved 100 employment managers in the Chicago area showed，too， that the number of women entering the field of computer science is on the rise， and that those already in the field are moving up. A significant increase in the number of women

2020年职称英语卫生类阅读判断练习（3） Online Cancer Chat with a Safety Net Cancer Research UK has launched an online chat forum for cancer patients to swap stories and share experiences on how to cope with such a devastating disease. But Cancer Chat is a forum with a difference： it has an information safety net. This means that a Cancer Research UK team will keep a watching brief to ensure that patients are not subjected to rogue "cancer cures" or scientifically unsound information. Anyone can have access to the messages posted on Cancer Chat but if people wish to post a message they will need to register. And Rebekah Gibbs,cancer patient and star of TV's Casualty has pledged her support for the new project."I think Cancer Chat is a brilliant idea," she said."I have written a public diary about what I went through with breast cancer and I have had such a heart-warming response from other people going through the same thing. "The idea of a Cancer Chat forum means you can share information about treatment and side effects and you can really open up about your feelings online in a way that can be difficult when talking to close friends and family.And with Cancer Research UK monitoring the forum people can be reassured about the quality of information being exchanged."
第五篇Tracking Down HIV In the summer of 1980, a patient had a strange purplish spot removed from below his ear. It was Kaposi’s sarcoma, a rare form of skin cancer. This patient also had lymph node swelling and exhaustion. In November 1980, a Los Angeles immunologist examined a young man who had diseases linked to immune system malfunctions. The doctor had a T-cell count taken of the patient’s blood. T-cells are a type of white blood cell that plays a key role1 in immune responses. The patient had no helper T-cells. By the end of 1980, 55 Americans were diagnosed with infections related to immune system breakdown; four had died. A year later the death toll was 74. Intravenous drug users had T-cell abnormalities. People who had received blood transfusions showed symptoms of immune system breakdown. By July 1982, 471 cases of the disease, now called Acquired Immune Deficiency Syndrome (AIDS), had been reported; 184 people had died. In April 1984, American virologist Dr. Robert Gallo isolated the pathogen, or disease producer, responsible for2 AIDS. He called it HTLV-III. In Paris, Dr. Luc Montagnier identified a virus he called LAV. An international panel of scientists determined that both men had found the same virus. It became known as Human Immunodeficiency virus (HIV). Blood banks began screening for HTV in 1985, but by then about 29,000 people had been infected through blood transfusions. Some 12,000 hemophiliacs had contracted HIV through blood-clotting products. By 1995, 477,900 Americans had AIDS; 295,500 had died.
2010年职称英语等级考试用书（理工类） 新增文章参考译文 第四部分阅读理解 第三篇 公民科学家 理解大自然对气候变化有怎样的反应需要监视世界各个角落的关键生命周期事件——花开、叶子的出现、第一只青蛙叫出春天的到来。但是生态学家不可能去到世界的各个角落，所以他们向非科学家求助，这些非科学家有时也被称作公民科学家。 气象科学家不可能足迹遍及天下。因为在世界上有如此多的地方，没有足够的科学家来观察它们。所以他们请求你来帮助观察全世界气候变化的迹象。公民科学家运动鼓励普通人根据自己的兴趣来观察某一个特定的方面——鸟儿、树木、花开等等——并把他们的观察结果发送到一个巨大的数据库来供专业科学家研究。这有助于数量有限的科学家得到如果只靠他们自己根本收集不到的巨大数据。就像公民记者帮助报道传统新闻报道方式所忽略的小型社区的相关信息一样，公民科学家也对他们所居住的环境很熟悉。所需要的就是每天或每周留出几分钟来搜集数据并发送过来。 一群科学家和教育家在去年发起了一个叫做纽约国家物候学的组织。“物候学”就是科学家们所说的在自然中研究每个事件的时间。 其中一个小组的首要尝试就是依靠科学家和非科学家来收集关于每年植物开花和长叶子的数据。这一项目叫做花季追踪计划，它收集遍布美国的各种各样的植物生长周期的数据。参与这一项目的人们——这一计划对所有人开放——把他们的观察记录在花季追踪计划网站上。 “人们不需要是植物学家——他们仅仅需要环视四周看看周围有什么。”Jennifer
Schwartz说，她是这项计划的教育顾问。“通过收集数据，我们就能够估算出气候变化对植物和生物群落会有怎样的影响。” 第六篇 北极冰山融化 地球的北极和南极都以冰冷闻名。但是，去年北冰洋上的冰含量跌到了历史最低点。 正常情况下，每年冬天在北极附近的北冰洋开始结冰，并在夏天缩减。但是多年以来，在夏天结束时冰的含量在下降。 自从1979年以来，每l0年在夏季末的冰覆盖量都下降11.4％。在1981到2000年之间，北极冰的厚度下降了22％——变成了l.13米这么薄。 去年，北极的冰雪覆盖达到了最薄的程度。在2007年夏天快结束的时候，冰层已经缩减到只覆盖四百二十万平方公里。这比那年的平均覆盖面积少38％，比两年前最低记录少23％。这个持续的趋势令科学家们万分担忧。 冰雪融化有许多原因，话雅图华盛顿大学的海洋学家张金伦说，有许多原因导致了冰层融化。极不寻常的强风去年刮过大西洋，风把大西洋中部的冰散去，留下大面积的薄冰和没有冰覆盖的海面。 科学家们还怀疑在大西洋上空有比过去越来越少的云层。晴朗的天空使更多的阳光照射大西洋。升高的温度使水和空气都变温暖。在去年大西洋的部分海域，表面温度比平均温度高3.5摄氏度，比历史最高点还高l.5摄氏度。 由于空气和水都变暖，冰从上面和下面都开始融化。在波弗特海的部分海域，阿拉斯加的北部和加拿大的西部，夏天开始时冰的厚度为3.3米，但到了季末仅仅为50厘米。 新的测量表明，情况远远比科学家们仅仅从表面上看到的要严重得多，新罕布什尔州汉
