1、Semco
At 21, Ricardo Semler became boss of his father-s business in Brazil, Semco, which sold parts for ships. Semler Junior worked like a madman, from 7:30 am. , until midnight every day. One afternoon, while touring a factory in New York, he collapsed. The doctor who treated him said, "There's nothing wrong with you. But if you continue like this, you'll find a new home in our hospital." Semler got the message. He changed the way he worked. In fact, he changed the way his employees worked too.
He let his workers take more responsibility so that they would be the ones worrying when things went wrong. He allowed them to set their own salaries, and he cut all the jobs he thought were unnecessary, like receptionists and secretaries. This saved money and brought more equality to the company. "Everyone at Semco, even top managers, meets guests in reception, does the photocopying, sends faxes, types letters and dials the phone."
He completely reorganized the office, instead of walls, they have plants at Semco, so bosses can't shut themselves away from everyone else. And the workers are free to decorate their workspace as they want. As for uniforms, some people wear suits and others wear T - shirts.
Semler says, "We have a sales manager named Rubin Agater who sits there reading the newspaper hour after hour. He doesn't even pretend to be busy. But when a Semco pump an the other side of the world fails and millions of gallons of oil are about to spill into the sea, Rubin springs into action.
He knows everything there is to know about our pumps and how to fix them. That's when he earns his salary. No one cares if he doesn't look busy the rest of the time."
Semco has flexible working hours, the employees decide when they need to arrive at work, The employees also evaluate their bosses twice a year. Also, Semco lets its workers use the company's machines for their own projects, and makes them take holidays for at least thirty days a year.
It sounds perfect, but does it work? The answer is in the numbers. In the last six years, Semco's revenues have gone from $ 35 million to $ 212 million. The company has grown from eight hundred employees to 3,000, Why?
Semler says it's because of "peer pressure". Peer pressure makes everyone work hard for everyone else. ____ In other words, Ricardo Semler treats his workers like adults and expects them to act like adults, And they do.

2、Blasts from the Past
1 Volcanoes were more destructive in ancient history. Not because they were bigger, but because the carbon they released wiped out life with greater ease.
2 Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions and mass extinctions. Not all volcanic eruptions killed off large numbers of animals, but all the mass extinctions over the past 300. million years coincided with huge formations of volcanic rock. To his surprise, the older the massive volcanic eruptions were, the more damage they seemed to do.
3 Wignall calculated the "killing efficiency" for these volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced. He found that size for size, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.
4 The Permian extinction, for example, which happened 250 million years ago, is marked by floods of volcanic rock in. Siberia that cover an area roughly the size of western Europe, Those volcanoes are thought to have pumped out about 10 gigatonnes of carbon as carbon dioxide, The global warming that followed wiped out 8 per cent of all marine genera at the time, and it took 5 million years far tire planet to recover.
5 Yet 60 million years ago in the late Palaeocene there was another huge amount of volcanic activity and global-warming but no mass extinction. Some animals did disappear but things returned to normal within ten thousands of years, "The most recent ones hardly have an effect at all," Wignall says. He ignored the extinction which wiped out the dinosaurs at the end of the Cretaceous, 65 million years ago, because many scientists believe it was primarily caused by the impact of an asteroid.
6 Wignall thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of C02 Ocean chemistry may also have played a role. As the supercontinents broke up and exposed more coastline there may have been more weathering of silica rocks. This would have encouraged the growth of phytoplankton in the oceans, increasing the amount of C02 absorbed from the atmosphere.
7 Vincent Courtillot, director of the Paris Geophysical Institute in France, says that Wignall's idea is provocative. But he says it is incredibly hard to do these sorts of calculations. He points out that the killing power of volcanic eruptions depends on how long they fasted. And it is impossible to tell whether the huge blasts lasted for thousands or millions of years.
8 Courtillot also adds that it is difficult to estimate how much lava prehistoric volcanoes produced, and that lava volume may not necessarily correspond to carbon dioxide or sulphur dioxide emissions.
Paragraph 5____

A.Killing Power of Ancient Volcanic Eruptions

B.Association of Mass Extinction with Volcanic Eruption

C.Calculation of the Killing Power of Older Eruptions

D.A Mass Extinction

E.Volcanic Eruptions That Caused No Mass Extinction

F.ccounting for the Killing Power of Older Eruptions

正确答案:E

答案解析:Volcanic eruptions that caused no mass extinction：没有造成大量生物灭绝的火山爆发。上面讲到了“较早的火山喷发在灭绝生物方面的效率至少是后来的火山喷发的10倍”。第五段就是对“后来的火山喷发”的灭绝生物能力不行的证明。

3、Happy Marriage, Happy Heart
Happily married people have lower blood pressure than unhappily married people or singles, a Brigham Young University study says.
On the other hand, even having a supportive social network did not translate into a blood pressure benefit for singles or unhappily married people, according to the study.
"There seems to be some unique health benefits from marriage. It's not just being named that benefits health-what's really the most protective of health is having a happy marriage," study author Julianne Holt Lunstad, a psychologist who specializes in relationships and health, said in a prepared statement.
The study included 204 married and 99 single adults who wore portable blood - pressure monitors for 24 hours. The monitors recorded blood pressure at random intervals and provided a total of about 72 readings.
"We wanted to capture participants' blood pressure doing whatever they normally do in everyday life. Getting one or two readings in a clinic is not really representative of the fluctuations (波动) that occur throughout the day," Holt Lunstad said.
Overall, happily married people scored four points lower on the blood pressure readings than single adults. The study also found that blood pressure among married people, especially those in happy marriages dropped more during sleep than in single people.
"Research has shown that people whose blood pressure remains high throughout the night are at much greater risk of heart disease than people whose blood pressure drops," Holt Lunstad said.
The study was published in the March 20 ____ of the journal Annals (年刊) of Behavioral Medicine.
The study also found that unhappily married adults have higher blood pressure than both happily married and single adults.
Holt Lunstad noted that married couples can encourage healthy habits in one another, such as eating a healthy diet and having regular doctor visits. People in happy marriages also have a source of emotional support, she said.

4、Nurse ! I Want My Mummy
When a child is ill in hospital, a parent's first reaction is to be with them.
Most hospitals now allow parents to sleep overnight with their child, providing a bed or so far on the ward.
But until the 1970s this practice was not only frowned upon, it was actively discouraged. Staff worried that the children were upset when their parents left, and so there was a blanket ban.
A concerned nurse, Pamela Hawthorn, disagreed and her study "Nurse! I want my mummy" published in 1974 , changed the face of paediatric nursing.
Martin Johnson, a professor of nursing at the University of Salford, said that the work of nurses like Pamela had changed the face of patient care.
"Pamela's study was done against the background of a lively debate in paediatrics and psychology as to the degree women should spend with children in the outside world and the degree to which they should be allowed to visit children in hospital. "
"The idea was that if mum came to visit a small child in hospital the child would be upset and inconsolable for hours. "
"Yet the nurse noticed that if mum did not come at all the child stayed in a relatively stable state but they might be depressed. "
"Of course we know now that they had almost given up hope that mum was eve coming back. "
"To avoid a little bit of pain they said that no one should visit. "
"But children were alone and depressed so Hawthorn said parents should be ____ to visit. "
"Dr Peter Carter, chief executive and general secretary of the Royal College of Nursing, said her work had been seminal. "
"Her research put an end to the days when parents handed their children over to strangers at the door of the hospital ward. "
"As a result of her work, parents and careers are now recognized as partners and are afforded the opportunity to stay with their children whilst they are in hospital, which has dramatically improved both parents' and children's experience of care. "

5、Population
The advantages and disadvantages of large population have long been a subject of discussion among economists. It has been argued that the supply of good land is limited . To feed a large population, inferior land must be cultivated and the good land worked intensively. produces less and this means a lower average income than could be obtained with a smaller population . Other economists have argued that a large population gives more scope for specialization and the development of facilities such as ports, roads and railways, ____
One of the difficulties in carrying out a worldwide birth control program lies in the fact that official attitudes to population growth vary from country to country depending on the level of industrial development and the availability of food and raw materials. In the developing country where a vastly expanded population is pressing hard upon the limits of food, space and natural resources, concern of government to plane a limit on the birth rate, whatever the consequences may be. In a highly industrialized society the problem may be more complex. A decreasing birth rate may lead to unemployment it results in a declining market for manufactured goods. When the pressure of population on housing declines, prices also decline and the building industry is weakened. Faced with considerations such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable or in decline.
