Sleeping Position Reveals Personality Traits

Whether it's curled up in the fetal position , flat on the stomach or stretched out across the bed, the way people sleep reveals their personality, a British sleep expert said. The expert has identified six common sleeping positions and what they mean. "We are all aware of our body language when we are awake but this is the first time we have been able to see what our subconscious says about us, " he said. Crouched in the fetal position is the most popular sleep pattern and favored by 51 percent of women, according to the results of the study he conducted for a large hotel group. Fetal sleepers tend to be shy and sensitive while people who assume the soldier position, flat on their back with arms at their sides, are quiet and reserved. Sleeping on one's side with legs outstretched and arms down in what he refers to as the log, indicates a social, easygoing personality. But if the arms are outstretched in the yearning position, the person tends to be more suspicious. The free fall, flat on the tummy with the hands at the sides of the head, is the most unusual position. Only 6.5 percent of people prefer it and they are usually brash and gregarious. Unassuming, good listeners usually adopt the starfish position — on the back with outstretched arms and legs.The expert, who identified the positions by comparing personality traits of people.

睡姿揭示人的性格

一 位英国睡眠专家曾说过： 无论你是像胎儿一样蜷缩着睡觉， 或是趴在床上睡， 还是四肢伸开平躺着睡， 睡觉的姿势揭示了你的性格。该专家归纳了六种常见睡觉姿势， 以及这些姿势的含义。“ 醒着的时候， 我们都知道自己的肢体语言， 但这是我们第一次知道自己的潜意识在说些什么， ”他说。他对一家大型酒店集团所做的研究结果表明： 像胎儿一样蜷缩着睡觉是最流行的睡觉姿势， 有51% 的妇女喜欢这种姿势。采用胎儿式睡姿的人往往比较害羞， 也很敏感； 而采用仰卧、双臂放在身体两侧的士兵式睡姿的人则比较安静， 也不愿说话。侧卧、两腿伸直、双臂自然下垂的睡姿称为原木式睡姿。采用这种睡姿的人喜欢社交活动， 容易相处。但是如果双臂伸出， 呈渴望状， 这种人往往比较多疑。自由式， 即俯卧， 双手放在头的两侧， 这是最特别的睡姿。只有6.5% 的人喜欢这样睡， 他们通常性情急躁， 爱社交。谦虚忠实的听众通常选择仰卧且四肢伸展的海星式睡姿。该专家通过比较人物性格特征、他们喜欢的睡姿和最常见的睡姿归纳出以上这些睡姿。他说人们一旦采用了某种睡姿就很难再改变。

如今， 很多年轻人谈恋爱的时候， 总想知道对方的性格到底如何， 以检验与自己是否般配。对此， 不同的人有不同的方法， 有的人算姓名笔画和生辰八字， 有的看星座、生肖和血型， 其实我们也不妨留意一下对方的睡姿。“江山易改， 睡姿难移”, 大多数人一生中不大可能改变睡眠姿势， 因而睡姿也给我们提供了一个了解自己和他人的很好方式。

1. 意识理论。他把人类的心理结构分为三层， 即意识( conscious) 、前意识( preconscious)和无意识( 即潜意识) 。他认为意识处于大脑表层， 是一个人所直接感知到的内容； 前意识主要是在意识与无意识之间起警戒作用， 阻止无意识的本能欲望进入意识之中； 无意识处于大脑底层， 毫无理性， 是决定人的行为和愿望的内在动力。

2. 这里的once 不是“ 一次”或“ 曾经”的意思， 不是副词， 而是连词， 意为“ 一旦， 一就”, 如： Once printed, this dictionary will be very popular! ( 一旦出版， 这本词典将会非常畅销！ )

英语阅读题六级 篇2

Caught in a squeeze between the health needs of aging populations on one hand and the financial crisis on the other, governments everywhere are looking for ways to slow the growth in health-care spending. Increasingly, they are looking to the generic-drugs (普通药物) industry as a savior. In November Japans finance ministry issued a report complaining that the countrys use of generics was less than a third of that in America or Britain. In the same month Canadas competition watchdog criticized the countrys pharmacies for failing to pass on the savings made possible by the use of generic drugs. That greed, it reckoned, costs taxpayers nearly C$1 billion a year.

Then on November 28th the European Commission issued the preliminary results of its year-long probe into drug giants in the European Union. The report reached a damning~, though provisional, conclusion: the drugs firms use a variety of unfair strategies to protect their expensive drugs by delaying the entry of cheaper generic opponents. Though this initial report does not carry the force of law (a final report is due early next year), it has caused much controversy. Neelie Kroes, the EUs competition commissioner, says she is ready to take legal action if the evidence allows.

One strategy the investigators criticize is the use of the "patent duster( 专利群)". A firm keen to defend its drug due to go off-patent may file dozens or hundreds of new patents, often of dubious merit, to confuse and terrify potential copycats and maintain its monopoly. An unnamed drugs firm once took out 1,300 patents across the EU on a single drug. The report also suggests that out-of-court settlements between makers of patented drags and generics firms may be a strategy used by the former to delay market entry by the latter.

According to EU officials, such misdeeds -have delayed the arrival of generic competition and the accompanying savings. On average, rite report estimates, generics arrived seven months after a patented drug lost its protection, though where the drug was a big seller the lag was four months. The report says taxpayers paid about q 3 billion more than they would have-had the generics gone on sale immediately.

But hang on a minute, Though many of the charges of bad behavior leveled at the patented-drugs industry by EU investigators may well be true, the report seems to let the generics industry off the hook(钩子) too lightly. After all, if the drugs giants stand accused, in effect, of bribing opponents to delay the launch of cheap generics, shouldnt the companies that accepted those "bribes" also share the blame?

56. Why are governments around the world seeking ways to reduce their health-care spending?

A) They consider the generic-drugs industry as a savior.

B) They are under the double pressure of aging group and financial crisis.

C) Health-care spending has accounted too large proportion.

D) Health-care spending has cost taxpayers too much income.

57. What can we learn from the report issued by the European Commission?

A) Drug firm will use just ways to protect their drags.

B) Cheaper generic drugs are easy to enter market,

C) The report has come to an ultimate conclusion.

D) The final report may lead to commissioners legal action.

58. The investigators seriously condemned the drug firms for__________.

A) they do not let their opponents to resort to the comet

B) they use clusters of patents to protect their products

C) they bribe the cheaper generic opponents

D) trey do not pass on the savings made by use of generic drugs

59. On average, the genetics will be delayed to enter the market by __________.

A) seven months

B) three months

C) four months

D) eleven months

60. Which of the following accords with the authors view?

A) Charges on patented-drug industry are anything but true.

B) Generics industry is a sheer victim in the competition.

C) Only drug giants are to blame.

D) Exclusion of generics industry from taking responsibility is questionable.

英语六级阅读理解专项练习题及答案 篇3

Section A

Culture shock is an occupational disease for people who have been suddenly transplanted abroad. Like most illness, it has its own symptoms and a cure.

Culture shock is accelerated by the anxiety that results from losing all familiar signs and symbols of social intercourse. Those signs include the thousand and one ways in which we orient ourselves to the situation of daily life: when to shake hands and what to say when we meet people, when and how to give tips, how to make purchases, when to accept and refuse invitations, when to take statements seriously and when not. These signs, which may be words, gestures, facial expressions, or customs, are acquired by all of us in the course of growing up and as much a part of our culture as the language we speak or the beliefs we accept. All of us depend for our peace of mind and our efficiency on hundreds of these cues, most of which we do not carry on the level of conscious awareness.

Now when an individual enters a strange culture, all or most of these familiar signs are removed. He or she is like a fish out of water. No matter how broad-minded or full of goodwill you may be, a series of supports have been knocked from under you, followed by a feeling of frustration and anxiety. People react to the frustration in much the same way. First they reject the environment which causes discomfort: "The ways of the host country are bad because they make us feel bad." For example, Americans who are in a strange land get together to grouse about the host country and its people, you can be sure they are suffering from culture shock. Another phase of culture shock is regression. The home environment suddenly assumes a tremendous importance. To a foreigner, everything becomes irrationally glorified. All the difficulties and problems are forgotten and only the good things back home are remembered. It usually takes a trip home to bring one back to reality.

47. What kind of people may suffer from culture shock?

48. According to the passage, the signs and cues which we are familiar with help us _________.

49. Most of the cues which we depend on for our peace of mind and our efficiency are obtained ___________.

50. According to the author, how would people who are suffering from culture shock feel?

51. Apart from rejecting the new environment, people who are suffering from culture shock may overestimate _________.

参考答案：

Section A

47. People who suddenly enter a strange culture

或People who are suddenly transplanted abroad.

48. orient ourselves to the situation of daily life.

49. unconsciously in the course of growing up

50. frustrated and anxious.

51. the home environment.

英语阅读题六级 篇4

The food irradiation process is a simple one. The new U.S. plant, Vindicator of Florida Incorporated in Mulberry, Fla., uses a material called cobalt 60 to irradiate food. Cobalt 60 is radioactive isotope (form) of the metallic element cobalt. Cobalt 60, which gives off radiation in the form of gamma rays, is also used for radiation therapy for cancer patients and for sterilizing hospital equipment. The radioactive isotope is created by bombarding cobalt with subatomic particles in a nuclear reactor. However, irradiation plants do not themselves contain nuclear reactors.

In the irradiation plant, food is exposed to thin rods of cobalt 60. The rods give off gamma rays, which disrupt chemical processes in contaminating organisms. The disruption breaks down the cell walls of organisms or destroys their genetic material. The dose, set by the U.S. Food and Drug Administration (FDA), is enough to kill organisms on food, but not enough to produce significant changes in the food itself.

Although irradiation slightly decreases the nutritive value of foods, the loss is less than that produced by some other methods of food preservation. Canning, for example, results in a much greater loss of nutrients.

Those who object to irradiation say that the process may create substances not found in nonirradiated food. Since the 1960’s researchers have studied irradiated food at microscopic levels to try to find such substances, called unique radiolytic products. After reviewing these studies, the FDA determined that compounds formed during irradiation are similar to substance found in nonirradiated foods and are not dangerous to consume.

Destruction of microorganisms that cause illness is an important goal of irradiation. About 250 million cases of food poisoning or 1 per person—occur every year in the U.S., according to FDA estimates. Food poisoning can cause vomiting, diarrhea, fever, headache—and, occasionally, death.

Because of the apparent safety of food irradiation, and the problems presented by contaminated food, scientific groups—including the American Medical Association, the World Health Organization, and the United Nations food and Agriculture Association—have voiced nearly universal support for the process. Worldwide, 38 nations have approved irradiation for 355 products.

Like microwave ovens, food irradiation has aroused apprehension and misunderstanding. Yet it has been scrutinized more thoroughly than other methods of food treatment that we have come to regard as safe, and it appears to be a method whose time has come.

1.Cobalt 60, besides irradiating food, is also employed to ___.

A.detect metallic flaws

B.run a nuclear reactor

C.cure cancer patients

D.strengthen concrete walls

2.Gamma rays used to irradiate food ___.

A.are generally not strong enough to destroy contaminating organisms

B.do not bring about significant changes in the food itself

C.may destroy some of the nutrients in the food

D.should be submitted to FDA for approval

3.Irradiated food ___.

A.certainly loses its nutritive value

B.maintains its nutritive value no different from the nonirradiated

C.keeps its nutritive value better than canned food

D.is recommended as the best of all preserved foods

4.With cases of food poisoning increasing, ___.

A.food irradiation should be carried out with care

B.it is more urgent to irradiate foods

C.medical researches into treatment of the diseased should be strengthened

D.Americans are beginning to accept food irradiation

5.The passage may be taken from ___.

A.a news report

B.a textbook of food processing

C.a book of popular science

D.a manual of food irradiation

答案：CBCCD

英语阅读题六级 篇5

Federal Reserve System, central banking system of the United States, popularly called the Fed. A central bank serves as the banker to both the banking community and the government; it also issues the national currency, conducts monetary policy, and plays a major role in the supervision and regulation of banks and bank holding companies. In the U.S. these function are the responsibilities of key officials of the Federal Reserve System: the Board of Governors, located in Washington, D.C., and the top officers of 12 district Federal Reserve banks, located throughout the nation. The Fed’s actions, described below, generally have a significant effect on U.S. interest rates and, subsequently, on stock, bond, and other financial markets.

The Federal Reserve’s basic powers are concentrated in the Board of Governors, which is paramount in all policy issues concerning bank regulation and supervision and in most aspects of monetary control. The board enunciates the Fed’s policies on both monetary and banking matter. Because the board is not an operating agency, most of the day-to day implementation of policy decisions is left to the district Federal Reserve banks, stock in which is owned by the commercial banks that are members of the Federal Reserve System. Ownership in this instance, however, does not imply control; the Board of Governors and the heads of the Reserve banks orient their policies to the public interest rather than to the benefit of the private banking system.

The U.S. banking system’s regulatory apparatus is complex; the authority of the Federal Reserve is shared in some instances for example, in mergers or the examination of banks with other Federal Deposit Insurance Corporation (FDIC). In the critical area of regulating the nation’s money supply in accordance with national economic goals, however, the Federal Reserve is independent within the government, Income and expenditures of the Federal Reserve banks and of the board of governors are not subject to the congressional appropriation process; the Federal Reserve is self-financing. Its income ($20.2 billion in 1992) comes mainly from Reserve bank holdings of income-earning securities, primarily those of the U.S. government. Outlays ($1.5 billion in 1992) are mostly for operational expenses in providing services to the government and for expenditures connected with regulation and monetary policy. In 1992 the Federal Reserve returned 416.8 billion in earnings to the U.S. treasury.

1.The Fed of the United States ___.

A.function as China Bank

B.is the counterpart of People’s Bank of China

C.is subjected to the banking community and government

D.has 13 top officers who can influence the American financial market

2.The fact that stock in the Fed belongs to commercial banks ___.

A.doesn’t mean the latter is in control

B.means the latter is in control

C.means the latter is subjected to the Reserve banks

D.means the Reserve banks orient the latter’s policies

3.Which of the following statements is not true according to the passage?

A.The fed is a very big, complex and significant system which comprises many local banks.

B.All the commercial banks are not the components of Federal Reserve System.

C.Board of governors is the supreme policy-makers of America.

D.District Reserve banks rather than Board of governors perform the day-to-day policies.

4.The authority of the federal Reserve ___.

A.has to be shared with other establishments.

B.is exclusive at other times

C.isn’t limited by comptroller of the Currency and FDIC

D.is limited by Board of governors

5.Income of the Board of governors ___.

A.is borrowed from the U.S. treasury

B.is used by the government to make various policies

C.comes from the U.S. Treasury

D.is not granted by the government

仔细阅读

46. A it is unfair to those climate-venerable nations.

细节题，题目定位词除了Paris climate agreement之外还有一个重点定位词critical，问作者为什么对此协议是批判态度，在文中并不是很明确找到。第一段交代这项协议的具体时间内容等，第二段才谈到作者的批判态度。即we reveal just how deep this injustice runs,作者认为这是不公的，this injustice指代前两句，遭遇气候伤害的国家(少数4%国家)却承担一大半全球温室气体排放的责任，这是不公的。injustice=unfair

47.C They hardly pay anything for the problem they have caused

细节题。定位词“free-riders”，这个词在第三段，冒号后解释说，通过大量温室气体排造成严重问题，同时却不用承担气候变化的代价。In other words后面的句子也在解释同一件事情。原文出现cost和problem 在正确答案中以pay和problem复现。

48.C They have to bear consequences they are not responsible for

细节题，定位词“forced-riders”和second-hand smokers，定位在第四段，who are suffering from climate impacts despite having scarcely contributed to the problem.这些forced-riders没有助长全球变暖这个问题但却要承担气候问题的不良后果。答案为近义词替换：bear consequences=suffer from impacts，be not responsible for=scarcely contribute to

49.B There is no final agreement on where it will come from

细节题，定位词“100 billion”，定位到第7段，该段出现核心考点“however”，说明整个段落对这笔资金的使用是转折后的评价，即负评价。答案应该选择B或C两个包含负评价的词之一(均出现no)。其中B There is no final agreement on where it will come from是对应转折后面的两个不足中的第二个不足，即对There is also very little detail on who will provide the funds or importantly who is responsible for their provision的同义改写，即协议中对谁提供资金及谁承担募集资金的责任没有做明确说明，探讨资金来源而非资金花费的方式。

50. D putting in effect the policies in the agreement at once

细节题，定位词urgent action 对应第8段(倒数第二段)，there must urgently be a meaningful mobilization of the policies outlined in the agreement即动用协定中拟定的政策，近义词替换put in effect(生效)=mobilization(动用)，及原词复现。

passage 2

51.C Teenagers’ mental problems are often too conspicuous not to be observed.

句子理解题。考查句子意思与上下文相同或相反，此处上下文无转折词，应读下一句话：Their risky behaviors can alert parents and teachers that serious problems are brewing.其意思是青少年的一些危险举动—喝酒吸毒等—能警告父母老师大事不妙了。对应答案青少年的心理问题是非常显而易见得观察到的。serious problems指心理问题，conspicuous behaviors指破折号中的危险举动的概括改写。

52. D Many hitherto unobserved youngsters may have psychological problems

细节题。对应第二段转折but a new study：有一些青少年(睡眠不足不爱活动等行为)可能会有着同样的得精神疾病(psychiatric symptoms)的危险，正确答案对此处是概括型改写，那些行为对应着unobserved youngsters，也与上文的易观察的`行为有着转折关系，psychological problems对应psychiatric symptoms。

53. B Their behaviors do not constitute a warning signal.

细节题，定位词invisible risk,对应第三段，直接给出原因句：because their behaviors are not usually seen as a red flag. 同义替换warning signal=red flag

54.A They are almost as liable to depression as the high-risk group

细节题，顺序原则+定位词invisible group，至定位句but the invisible group wasn’t far behind the high-risk set,with more than 13%of them exhibiting depression. 定位即答案，两句话均表示，这一群体和高危青少年群体在表现抑郁症的比例上几乎不相上下。

55. B it provides new early-warning signals for identifying teens in trouble.

细节题，Carli和significance 对应最后一段it provides new early-warning signs for parents teachers and mental healthcare providers.
