【2012年度】职称英语【卫生类】新增文章完整版.doc

2012年卫生类教材新增文章今年卫生类的新增文章还是集中在阅读理解和完形填空两部分，共增加新增文章10篇。其中阅读理解的文章总共增加5篇，A级新增两篇，B级新增两篇，C级新增一篇；完形填空部分也是一共增加5篇，其中A级增加3篇，B级增加1篇，C级增加1篇。1、卫生类新增文章难度变化分析1）阅读理解。去年的卫生类的新增文章的题目是比较难的，今年整体难度并没有增加。今年的C级的文章在难度上都没有太大的变化。A级和B级新增文章难度要大一些，难度主要体现在：第一点阅读理解的文章比较长，段落比较少的文章其段落很长。句子也是以长句子为主；第二点题面句子都比较长；第三点是阅读理解题目中，推断类和态度类的题目比较多，难度要大一些。2）完形填空。完形填空的难度变化不是很大。其中A级的完形填空题目中的“HealthProfile健康概貌”这篇文章的难度是C级难度。文章段落和题目都相对比较简单一些。所以整体而言，完形填空新增文章的题目难度有所降低，但是备考的范围增加了，因为A级要准备3篇文章。3、卫生类文章替换规律变化1）2012年的阅读理解和完形填空的新增文章总数都是5篇，这5篇的分布情况阅读理解是1（C）+2（B）+2（A），完型是1（C）+1（B）+3（A）的分配规律。C级的这两种题型新增的均是1篇。2）与去年（2011年新增文章）相比，新增文章替换数量的变化：阅读理解发生的变化是：去年A级和C级各新增1篇，B级新增两篇，比其他各个级别多新增一篇；今年整体数量上增加1篇，这一篇是A级新增，也就是今年A级比去年的新增数量多了一篇。完型填空发生的变化是：去年完形填空级新增篇，级新增2篇，C级新增1篇；今年不仅是整体数量上增加了一篇，在分布上也发生了改变，今年的A级新增了3篇文章，比去年新增文章多出了两篇，而B级的新增情况是减少了一篇，今年只是新增了一篇。整体的分析而言，不管是阅读理解和完形填空，C级文章在新增文章数量上都没有发生改变，而B级完形填空的新增文章数量均发生了变化，A级的阅读理解和完型填空在新增文章数量上都发生了变化。3）第三点值得注意的是，今年的教材很多替换掉的是去年的新增文章，这和以前每年以替换掉很老的文章是不同的。比如今年C级的“EatHealthy健康饮食”替换掉的是去年的新增文章“AttitudestoAIDSNow对待艾滋病的最新态度”；A级的“AHealthProfile健康概貌”替换掉了去年的“Homosexuals同性恋者”。4）今年卫生类的新增文章大部分是选自综合以及理工类教材中原有的老文章。这也是今年才有的新的替换趋势。这也正是从侧面反应了今年的卫生类文章题材的变化，题材会更偏向于综合类。3、卫生类新增文章题材分析1）今年卫生类的新增文章在题材上面最显著的变化就是专业性侧重点的转变。今年的新增文章没有出现疾病类以及药物类讲解文章。文章的题材均是有向综合类题材靠拢的趋势。文章内容更加贴近于生活，贴近于社会生活热点。2）卫生类今年新增文章主题大部分是和饮食、睡眠、健康、寿命等相关的健康常识和健康理念。这些也均是生活中的热点问题。选择的题材更具有新闻价值和社会关注度，这在某种程度上来看，也是在考察考生对社会焦点问题的关注和了解2012年职称英语综合类新增文章篇目注：1、2012年职称英语卫生类新增阅读理解第八篇 Eat HealthyClean your plate! and Be a member of the clean-plate -club! Just about every kid in the US has heard this from a parent or grandparent. Often，its accompanied by an appeal: Just think about those starving orphans in Africa! Sure, we should be grateful for every bite of food. Unfortunately, many people in the US take too many bites. Instead of staying clean the plate, perhaps we should save some food for tomorrow.According to news reports, US restaurants are partly to blame for the growing bellies. A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate quantity with value and most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little.Barbara Rolls, a nutrition professor at Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, the same time that the American waistline began to expand.Health experts have tried to get many restaurants to serve smaller portions. Now, apparently，some customers are calling for this too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believe restaurants serve portions that are too large; 23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who cant afford fine dining still prefer large portions. Seventy percent of those earning at least $150,000 per year prefer smaller portions; but only 45 percent of those earning less than $25,000 want smaller.Its not that working class Americans dont want to eat healthy. Its just that，after long hours at low-paying jobs，getting less on their plate hardly seems like a good deal. They live from paycheck to paycheck ，happy to save a little money for next years Christmas presents.词汇:orphan /?:f?n / n.孤儿belly /beli/ n.肚子nutrition / nju:tri?n / n.营养waistline / weistlain / n.腰围paycheck / peit?ek / n.薪金支票注释:1.

Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rates, not an increase in birthrates, that has led to the population explosion.Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times of famine, infants might be allowed to die because they could not survive if their parents starved, whereas if the parents survived they could have another child. In most contemporary societies, people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement, somebody else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illness than young or middle-aged people; unless they have wealth or private or government insurance, they must often go on welfare if they have a serious illness.When older people become senile or too weak and ill to care for themselves, they create grave problems for their families. In the past and in some traditional cultures, they would be cared for at home until they died. Today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. To meet this need, a great many nursing homes and convalescent hospitals have been built. These are often profit-making organizations, although some are sponsored by religious and other nonprofit groups. While a few of these institutions arc good, most of them are simply dumping grounds for the dying in which care is given by poorly paid, overworked, and under-skilled personnel.词汇：dependency / dipend?nsi/ n.依赖性contemporary / k?ntemp?r?ri / .现代的obligation / ,?bliei?n / n. 义务insurance / in?u?r?ns / n. 保险welfare / welf? / n.福利senile / si:nail / dj. 衰老的grave /reiv / dj. 严肃的convalescent /,k?nv?les?nt/ dj.康复的sponsor / sp?ns?/ v. 发起，资助institution /,institju:?n / n. 机构注释:1.

Perchance to file? Findings published online this week by the Proceedings of the National Academy of Sciences further support the theory that the brain organizes and stows memories formed during the day while the rest of the body is catching zzzs.Gyorgy Buzsaki of Rutgers University5 and his colleagues analyzed the brain waves of sleeping rats and mice. Specifically, they examined the electrical activity emanating from6 the somatosensory neocortex (an area that processes sensory information) and the hippocampus, which is a center for learning and memory. The scientists found that oscillations in brain waves from the two regions appear to be intertwined. So-called sleep spindles (bursts of activity from the neocortex) were followed tens of milliseconds later by beats in the hippocampus known as ripples. The team posits that this interplay between the two brain regions is a key step in memory consolidation. A second study, also published online this week by the Proceedings of the National Academy of Sciences, links age-associated memory decline to high glucose levels.Previous research had shown that individuals with diabetes suffer from increased memory problems. In the new work, Antonio Convit of New York University School of Medicine and his collaborators studied 30 people whose average age was 69 to investigate whether sugar levels, which tend to increase with age, affect memory in healthy people as well. The scientists administered11 recall tests, brain scans and glucose tolerance tests, which measure how quickly sugar is absorbed from the blood by the bodys tissues. Subjects with the poorest memory recollection, the team discovered, also displayed the poorest glucose tolerance. In addition, their brain scans showed more hippocampus shrinkage than those of subjects better able to absorb blood sugar.Our study suggests that this impairment12 may contribute to the memory deficits13 that occur as people age. Convit says. And it raises the intriguing possibility that improving glucose tolerance could reverse some age-associated problems in cognition.14 Exercise and weight control can help keep glucose levels in check15, so there may be one more reason to go to the gym.词汇：perchance p?t?:ns adv. 偶然；可能online ?nlain n. 在线的stow st?u vt. 贮藏，堆装emanate em?neit vi. 发源somatosensory ,s?um?t?sens?ri adj. 体觉的neocortex ,ni:?uk?:teks n. 新（大脑）皮质oscillation ,?silei?n n. 振荡intertwine ,int?twain v. 缠绕spindle spindl n. 纺锤体ripple ripl n. 波动，脉动diabetes ,dai?bi:ti:z n. 糖尿病recollection ,rek?lek?n n. 回忆shrinkage ?ri?kid? n. 收缩impairment imp?m?nt n. 损伤intrigue intri: n. 引起。兴趣（或好奇心）cognition k?ni?n n. 认识注释：1. file memories：归档并储存记忆。 file：意为 to put or keep (papers,etc. ) in useful order for storage or reference（把归档）。2.

Many now think that using genetic treatments we will soon be able to extend human life to at least 140 years. This seems a great idea. Think of how much more time we could spend chasing our dreams，spending time with our loved ones，watching our families grow and have families of their own.Longer life would give us a chance to recover from our mistakes and promote long term thinking, says Dr Gregory Stock of the University Of California School Of Public Health. It would also raise productivity by adding to the year we can work.Longer lives dont just affect the people who live them. They also affect society as a whole. We have war，poverty，all sorts of issues around，and I dont think any of them would be at all helped by having people live longer, says US bioethicist Daniel Callahan.The question is What will we get as a society? I suspect it wont be a better society.It would certainly be a very different society. People are already finding it more difficult to stay married. Divorce rates are rising. What would happen to marriage in a society where people lived for 140 years? And what would happen to family life if nine or 10 generations of the same family were all alive at the same time?Research into ageing may enable women to remain fertile for longer. And that raises the prospect of having 100-year-old parents，or brothers and sisters born 50 years apart. We think of an elder sibling as someone who can protect us and offer help and advice. That would be hard to do if that sibling came from a completely different generation.Working life would also be affected，especially if the retirement age was lifted. More people would stay in work for longer. That would give us the benefits of age-skill，wisdom and good judgment.On the other hand，more people working for longer would create greater competition for jobs. It would make it more difficult for younger people to find a job. Top posts would be dominated by the same few individuals，making career progress more difficult. And how easily would a 25-year-old employee be able to communicate with a 125-year-old boss?Young people would be a smaller part of a society in which people lived to 140. It may be that such a society would place less importance on guiding and educating young people，and more on making life comfortable for the old.And society would feel very different if more of its members were older. There would be more wisdom，but less energy. Young people like to move about. Old people like to sit still. Young people tend to act without thinking. Old people tend to think without acting. Young people are curious and like to experience different things. Old people are less enthusiastic about change. In fact ，they are less enthusiastic about everything.The effect of anti-ageing technology is deeper than we might think. But as the science advances，we need to think about these changes now. If this could ever happen，then wed better ask what kind of society we want to get， says Daniel Callahan. We had better not go anywhere near it until we have figure those problems out.词汇:mice / mais / n. 老鼠(复数)sibling / sibli? / n. 兄弟姐妹bioethicist / n. 生物伦理学家注释:1. brothers and sisters born 50 years apart 出生年份相隔50年的兄弟姐妹2. We had better not go anywhere near it 我们最好离它远点，这里的it指代前面讲的 anti-ageing technology.+第四十篇 Some People Do Not Taste Salt Like OthersLow-salt foods may be harder for some people to like than others，according to a study by a Penn State College of Agricultural Sciences food scientist. The research indicates that genetic factors inf1uence some of the difference in the levels of salt we like to eat.Those conclusions are important because recent ，well-publicized efforts to reduce the salt content in food have left many people struggling to accept fare that simply does not taste as good to them as it does to others，pointed out John Hayes，assistant professor of food science ，who was lead investigator on the study.Diets high in salt can increase the risk of high blood pressure and stroke. That is why public health experts and food companies are working together on ways to help consumers lower salt intake through foods that are enjoyable to eat. This study increases understanding of salt preference and consumption.The research involved 87carefully screened participants who sampled salty foods such as soup and chips，on multiple occasions ，spread out over weeks. Test subjects were 45 men and 42 women ，reportedly healthy ，ranging in age from 20 to 40 years. The sample was composed of individuals who were not actively modifying their dietary intake and did not smoke cigarettes. They rated the intensity of taste on a commonly used scientific scale，ranging from barely detectable to strongest sensation of any kind.Most of us like the taste of salt. However，some individuals eat more salt ，both because they like the taste of saltiness more ，and also because it is needed to block other unpleasant tastes in food. said Hayes. Supertasters，people who experience tastes more intensely ，consume more salt than do nontasters. Snack foods have saltiness as their primary flavor ，and at least for these foods， more is better ，so the supertasters seem to like them more. However ，supertasters also need higher levels of salt to block unpleasant bitter tastes in foods such as cheese ，Hayes noted. For example ，cheese is a wonderful blend of dairy flavors from fermented milk ，but also bitter tastes from ripening that are blocked by salt , he said. A supertaster finds low-salt cheese unpleasant because the bitterness is too pronounced.Hayes cited research done more than 75 years ago by a chemist named Fox and a geneticist named Blakeslee ，showing that individuals differ in their ability to taste certain chemicals. As a result ，Hayes explained ，we know that a wide range in taste acuity exists ，and this variation is as normal as variations in eye and hair color.Some people ，called supertasters，describe bitter compounds as being extremely bitter ，while others ，called nontasters，find these same bitter compounds to be tasteless or only weakly bitter. he said. Response to bitter compounds is one of many ways to identify biological differences in fo
