When scientists accidentally killed what turned out to be the world’s oldest living creature, it was bad enough. Now, their mistake has been worsened after further research found it was even older – at 507 years.
The ocean quahog, a type of deep-sea clam, was dredged (捕捞) alive from the bottom of the North Atlantic near Iceland in 2006 by researchers. They then put it in a fridge-freezer, as is normal practice, unaware of its age. It was only when it was taken to a laboratory that scientists from Bangor University studied it and concluded it was 400 years old.
The discovery made it into the Guinness Book of World Records. However, by this time, it was too late for Ming the Mollusc(软体动物), named after the Chinese dynasty when its life began. Unfortunately researchers who calculated Ming’s age killed it instantly by opening its shell.
The researchers opened the ancient clam up to judge its age by counting growth rings inside. But the rings were so close together that scientists ended up having to count the rings on the outside to be accurate, leading CBS journalists to point out that if scientists had just started there, Ming could have lived on. Now, after examining the quahog more closely, using more advanced methods, the researchers have found the animal was actually 100 years older than they first thought.
Dr Paul Butler, from the University’s School of Ocean Sciences, said: “We got it wrong the first time and maybe we were a bit hasty publishing our findings back then. But we are absolutely certain that we’ve got the right age now.” The mollusc was born in 1499 – just seven years after Columbus discovered America and before Henry VIII had even married his first wife, Catherine of Aragon in 1509.
A quahog’s shell grows by a layer every year, in the summer when the water is warmer and food is plentiful. It means that when its shell is cut in half, scientists can count the lines in a similar way that trees can be dated by rings in their trunks.
Jan Heinemeier, associate professor at the University of Denmark, who helped date Ming, told Science Nordic: “The fact that we got our hands on a 507-year-old animal is incredibly fascinating, but the really exciting thing is of course everything we can learn from studying the mollusk.”At first, the scientists found that _____________.

The British National Health Service (NHS) was set up in 1948 and was designed to provide equal basic health care, free of charge, for everybody in the country. Before this time health care had to be paid for by individuals.
Nowadays central government is directly responsible for the NHS although it is administered by local health authorities. About 83 percent of the cost of the health service is paid for by general taxation and the rest is met from the National Insurance contributions paid by those in work. There are charges for prescription and dental care but many people, such as children, pregnant women, pensioners, and those on Income Support, are exempt from payment.
Most people are registered with a local doctor (a GP, or General Practitioner) who is increasingly likely to be part of a health centre which serves the community.
As the population of Britain gets older, the hospital service now treats more patients than before, although patients spend less time in hospital. NHS hospitals—many of which were built in the nineteenth century—provide nearly half a million beds and have over 480, 000 medical staff. The NHS is the biggest employer in Europe although Britain actually spends less per person on health care than most of her European neighbours.
During the 1980s there was considerable restructuring of the Health Service with an increased emphasis on managerial efficiency and the privatization of some services (for example, cleaning). At the end of the 1980s the government introduced proposals for further reform of the NHS, including allowing some hospitals to be self-governing, and encouraging GPs to compete for patients. Patients would be able to choose and change their family doctor more easily and GPs would have more financial responsibility. The political questions continue of how much money should be provided to support the NHS and where it should come from. We can know from the first paragraph that ______.
| A．the original aim of the NHS was to provide equal basic health care for everybody |
| B．people didn’t have to pay for health care since the NHS was set up |
| C．patients were charged for receiving health care before 1948 |
| D．the NHS was an organization which gave free advice to villagers |
. What do we know about the NHS?
| A．It’s managed by the central government. |
| B．Its cost is mainly paid for by the National Insurance contributions. |
| C．It hires more people than any other unit in Europe. |
| D．Fewer patients go to its hospitals than before because they spend less on health care. |
All the following statements about GPs are true except that they ______.
| A．take care of the local people’s health |
| B．often take part in competitions to see who is the best |
| C．work under high pressure nowadays |
| D．have more responsibilities than before |
What does the underlined word “exempt” probably mean?
| A．suffering | B．different | C．prevented | D．free |
The biggest problem for the NHS is ______.
| A．many hospitals are too old to be used |
| B．some services are in the charge of individuals |
| C．more and more patients go to GPs for treatment |
| D．there is not enough money for further reform |
Happiness is U-shaped, for we are happier at the start and end of our lives but hit a slump when we are middle-aged, British and US researchers say.
Economists from the University of Warwick, central England, and from Dartmouth College, New Hampshire, looked at data on the mental health of two million people from 80 countries.
In Britain, the probability of depression for men and women peaks at around 44 years of age, Warwick University said in a press release.
In the United States, though, ________________________between men and women. Among women, unhappiness peaked at around the age of 40, whereas among men, it was about 50.
But the U-shape of happiness is constant around the world, and mid-life depression occurs regardless of marital status(婚姻状况), changes in job or income.
The study appears in Social Science & Medicine, published by the Dutch publishing house Elsevier.
"It happens to men and women, to single and married people, to rich and poor, and to those with and without children." said co-author Andrew Oswald.
One possibility may be that people realize they won't achieve many of their ambitions at middle age. The researchers said.
Another reason could be that after seeing their fellow middle-aged peers begin to die, people begin to value their own remaining years and embrace life once more.
But the good news is that if people make it to aged 70 and are still physically fit, they are on average as happy and mentally healthy as a 20-year old.
"For the average persons in the modern world, the dip in mental health and happiness comes on slowly, not suddenly in a single year," Oswald said. "Only in their fifties do people emerge from this low period.

The hospital burn unit is a popular place on the day after Thanksgiving. I found that out three years ago, when my 18-month-old daughter touched a radiator pipe while playing around our friends' farmhouse. Instead of feasting on leftover stuffing, I rushed my child as she screamed to hospital. Instead of getting a jump on my Christmas shopping, I learned how to take care of second-degree burns.
Our story had a happy ending. With weeks of twice-daily treatments at Mommy and Papa's kitchen-table burn clinic, my daughter's hands healed. But other children we saw at the outpatient burn clinic weren't so lucky. I saw hands _____________________, a mouth that would never smile straight, a scalp that would never grow hair. All the parents had stories of accidents as easy as ours: a cup of tea knocked from a side table, a tumble (摔倒) into a space heater. "Heaters and soup," one veteran nurse told me at the hospital. "That's all it is. Heaters and soup."
Most of the injuries were to hands and wrists, and most came from contact with hot liquids or from touching hot objects. Not only do small children not realize the danger posed by hot objects; their skin is much thinner than that of adults. They burn more quickly, and the burns tend to be deeper and more severe.
Traditional fire safety education focused on preventing fires. The number of children injured by playing with fire has declined substantially when the Consumer Product Safety Commission required that cigarette lighters be child-resistant. "We know people know about smoke alarms," says Chrissy, program manager for Safe Kids USA, a nonprofit that works to reduce childhood injuries. Now, fire safety experts hope that public education efforts will turn to burns that can be just as terrible as injuries caused by flame.

Modern life is a lot les s to the advantage of friendships and neighborliness than it used to be. The average American moves every five years. People drive straight into their garages, hire lawn services, hang out in their backyards instead of their front porches (前走廊). These days, neighbors don't even know each other's names.
Good neighbors and good friends are a lot like electricity or running water: We don't know how much we depend on them until we don't have them. In fact, the authors of a recent book, Refrigerator Rights, claim that refrigerators are signs of close relationships--after all, you wouldn't snatch a drumstick(鸡腿) from the refrigerator of a stranger.
The surprising thing is that all it takes to strengthen your relationship with friends and neighbors is respect for their feelings, concern for their property, and a helping hand when it's needed. Here's how to develop your relationships with two types of vitally important people in your life.
_________________. A true friend doesn't flee when changes occur. The sign of a good friend is one who stays true through it all--marriage, parenthood, new jobs, new homes, the losses. Just because situations change doesn't mean the person has to.
Friendships fade away if there isn't an balance between the give and the take. So make sure you aren't being a burden to your friends. Be sensitive to how much your friend can and can't offer you--be it time, energy, or help -- and don't step over the line. Meanwhile, friendships that drain(耗尽) you will not last. If a friendship is out of balance in this way, you'll need to talk the situation through.

A true friend will stay the same even when the situations change.
