Your grandpa probably complained that rain was coming---he could feel it in his knees. We wouldn’t want to question an elder’s wisdom, but is there any scientific basis in his claims? One expert, Elaine Husni, director of Cleveland Clinic’s Arthritis(关节炎) and Musculoskeletal Center, explains the effects of barometric pressure (气压) and why these aches and pains could be telling.
Dr. Husni says that many, but not all, of her osteoarthritis patients complain that weather does influence their pain levels. “There is some consensus that lower barometric pressure and dropping temperatures correlate with more joint pain,” says the Cleverland doctor. Barometric pressure---essentially the weight of the air around us---drops when it gets colder. The thinking, she explains, is that lightness can cause the thin lining known as the joint capsule(关节囊)， which surrounds joints and maintains lubrication(润滑), to expand and stretch nerves, causing pain. A similar phenomenon can occur with humidity changes: There can be shifts in pressure that cause swelling around the joints, Dr. Husni says.
Theories include that “patients with arthritis already have inflammation(炎症) of their joints(specifically around the joint capsule) so any additional changes in the atmosphere could be detected more easily,” she says. “Perhaps the nerve endings are more sensitive in patients with arthritis.”
People with migraines (偏头痛) sometimes insist they feel headaches coming on when the air turns cold and the air pressure drops. These are called barometric pressure headaches, and a small study of 31 migraine sufferers in Naples, Italy, found that low pressure can lead to constricted(收缩的) blood vessels and result in more severe headaches, though the reasons, according to scientists, aren’t totally clear.
Dr. Husni is quick to point out that clinical studies have been conducted to find direct correlations between patients with hip or knee pains and changes in the weather, but the results were mixed. “There does seem to be a loose association between certain temperature variables like barometric pressure, cold temperatures and humidity and increased joint pain, but it isn’t so easy for patients to say with precision, ‘It will be 60 degrees and rainy tomorrow,’” she says. While many patients do feel more pain when it gets cold or humid, “they are not psychic(灵媒). In studies, they couldn’t predict the weather with accuracy.”
The studies Dr. Husni cites don’t pinpoint (准确描述) an exact time of when pain is set off by changing temperatures, nor has she seen evidence that certain climates are better for those with joint pain. “A lot of people with osteoarthritis say they do better in warmer climates, but the changes in climate aren’t always clinically meaningful,” says the joint expert. She cites a study that tracked online searches for terms related to arthritis and knee and hip pain and weather changes across 5 years in 50 American cities. When temperatures fell to between minus 5℃ and 30℃, search volumes(量) for hip pain increased by 12 index points, and knee pain increased by 18 index points; above 30℃, search volumes dropped by 7 index points. Still, says Dr. Husni, the study didn’t prove predictive abilities---just curiosity. “It’s not like you need to move to a warmer climate,” she says.
Blustery(大风的) weather may indeed increase pain in those who suffer from joint pain, but Dr.Husni suggests some basic fixes. No matter your local climate, keep your core warm and dry, she says. A sweater, scarf and gloves are perfectly fine well into March. No hard evidence suggests that applying heat or cold will eradicate joint pain. But “if an ice pack feels good or a heat pad helps, I’m not going to stop my patients from using them,” she says.
Anti-inflammatory medications are also go-tos, but Dr. Husni encourages patients with arthritis and other joint discomfort to seek medical advice. “Consult your doctor, who can treat you personally, she says. “Osteoarthritis affects 27% of Americans, and there are a lot of experts out there. Get diagnosed, get help, and you don’t have to suffer in bad weather.

The concept of a “born leader” seems so fanciful that it belongs on the cover of a bad business book. But it turns out that born leaders are real, and researchers have discovered a key factor, which isn’t genes, parents, or peers, but birth order.
First-born children are 30 percent more likely to be CEOs or politicians, according to a new paper by several economists, Sandra E. Black at the University of Texas-Austin, and Bjorn Ockert and Erik Gronqvist at Sweden’s Institute for Evaluation of Labor Market and Education Policy. The paper, which only looked at boys, found that first-borns stay in school longer, make more money, have a higher IQ, and even spend more time on homework than on television,
The idea that birth order might shape personality goes back at least to the 1920s, when Alfred Adler theorized that first-born children develop a “taste for power” at a young age, since they can dominate their younger siblings. He went on to say young children are spoiled and become dependent on their parents (the “baby of the family” effect), while middle children, being often in a war for their parents’ attention, are status-conscious and naturally competitive.
Obtaining personality from birth may strike you. But Adler’s hypotheses (假说) have held up in numerous studies. In a 2013 paper, “Strategic Parenting, Birth Order and School Performance,” V. Joseph Hotz, a professor of economics at Duke University, and Juan Pantano, a professor of economics at Washington University in St. Louis, used American data to show that school performance declines with birth order.
The researchers chalked their findings up to what they called the “reputational model of strategic parenting.” Put simply, parents invest a lot of time in establishing rules for their first child, building a reputation for toughness that they hope will pass down to later children. As a result, first-borns are doubly blessed—having too much of their parents’ attention, and then entrusted to act as the rules enforcer of the family, which helps them build intelligence, discipline, and leadership qualities. In the survey, parents report that they consider their older children more successful, and they are less likely to discipline their later-born children for improper behaviors, such as acting up or not doing homework.
This new study relies on Swedish data, and it comes to a similar conclusion. First-borns aren’t just healthier or smarter, but also they score higher on “emotional stability, persistence, social outgoingness, willingness to assume responsibility and ability to take the initiative.” Its researchers ruled out genetic factors; in fact, they uncovered evidence that later-born children might be healthier than first-borns.
Instead, the differences among siblings had everything to do with family dynamics in the children’s early years. First, having more children means parents can spend less time on each child, and as the parental investment declines, so may IQ.
Second, the most important effect, the researchers said, might not be the “strategic parenting” but something more like “strategic brothering.” As siblings compete for their parents’ love (or ice cream, or toys), they occupy certain positions---older siblings demonstrate their competence and power, while younger siblings develop more creative strategies to get attention. This effect seems particularly strong among later-born boys with older brothers. Younger brothers are much more likely to enter “creative” occupations ---like architect, writer, actor, singer, or photographer---if they have older brothers, rather than older sisters. In other words, among young brothers, specialization within the family forecasts specialization in the workforce.
There is a considerable implication in this idea that family dynamics during childhood can shape adult personality. Young children are highly sensitive to their environment, in ways that often have lasting effects.

Even then my only friends were made of paper and ink. At school I had learned to read and write long before the other children. Where my school friends saw notches of ink on incomprehensible pages, I saw light, streets and people. Words and the mystery of their hidden science fascinated me, and I saw in them a key with which I could unlock a boundless world, a haven from that home, those streets, and those troubled days in which even I could sense that only a limited fortune awaited me. My father didn’t like to see books in the house. There was something about them---apart from the letters he could not recognize---that offended him. He used to tell me that as soon as I was ten he would send me off to work and that I’d better get rid of all my scatterbrained ideas if I didn’t want to end up a loser, a nobody. I used to hide my books under the mattress and wait for him to go out or fall asleep so that I could read. Once he caught me reading at night and flew into a rage. He tore the book from my hands and flung it out of the window.
“If I catch you wasting electricity again, reading all this nonsense, you’ll be sorry.”
My father was not a miser and, despite the hardships we suffered, whenever he could he gave me a few coins so that I could buy myself some treats like the other children. He was convinced that I spent them on sunflower seeds, or sweets, but I would keep them in a coffee tin under the bed, and when I’d collected enough coins I’d secretly rush out to buy myself a book.
My favorite place in the whole city was the Sempere & Sons Bookshop on Calle Santa Ana. It smelled of old paper and dust and it was my refuge. The bookseller would let me sit on a chair in a corner and read any book I liked to my heart’s content. He hardly ever allowed me to pay for the books he placed in my hands, but when he wasn’t looking I’d leave the coins I’d managed to collect on the counter before I left. It was only small change---if I’d had to buy a book with that pittance (极少的报酬), I would probably have been able to afford only a booklet of cigarette papers. When it was time for me to leave, I would do so dragging my feet, a weight on my soul. If it had been up to me, I would have stayed there forever.
One Christmas Sempere gave me that best gift I had ever received. It was an old volume, read and experienced to the full.
“Great expectations, by Charles Dickens,” I read on the cover.
I was aware that Sempere knew a few authors who frequented his establishment and, judging by the care with which he handled the volume, I thought perhaps this Mr. Dickens was one of them.
“A friend of yours?”
“A lifelong friend. And from now on, he’s your friend too.”
That afternoon I took my new friend home, hidden under my clothes so that my father wouldn’t see it. It was a rainy winter, with days as gray as lead, and I read Great Expectations about nine times, partly because I had no other book at hand, partly because I did not think there could be a better one in the whole world and I was beginning to suspect that Mr. Dickens had written it just for me. Soon I was convinced that I didn’t want to do anything else in life but learn to do what Mr. Dickens had done.

Humans kill large carnivores---a category of animals that includes wolves, bears, lions, tigers and pumas---at more than nine times their death rate in the wild. Although they may not be our prey (猎物) in the traditional sense, new research shows that some of the world’s biggest carnivores are responding to humans in a way that resembles how prey animals react to predators (捕食者). Biologists at the Santa Cruz Puma Project, an ongoing research effort in the mountains of California’s central coast, report that even the scary puma, or mountain lion, shows its fearful side when people are around.
In a recent study, the researchers followed 17 mountain lions outfitted with GPS collars (项圈) to the animals’ deer kill sites. Once the cats naturally left the scene between feedings, ecologist Justin A. Smith, now at the University of California Berkeley, and her team trained motion-activated cameras on the prey bodies. On the animals’ return, the cameras triggered nearby speakers, which broadcast recordings of either frogs croaking (呱呱叫) or humans conversing.
The pumas almost always fled immediately on hearing the human voices, and many never returned to resume feeding or took a long time to do so. But they only rarely stopped eating or fled when they heard the frogs. They also spent less than half as much time feeding during the 24 hours after first hearing human chatter, compared with hearing the frogs, the team reported.
The human presence in such a situation has far-reaching consequences. A previous study found that Santa Cruz pumas living near residential areas killed 36 percent more deer than those in less populated places. The new finding could explain why: if the cats are scared away from their kills before they finish feeding, they may be taking more prey to compensate. And fewer deer could mean more plants go uneaten, according to Chris Darimont, a professor of conservation science at the University of Victoria in British Columbia, who was not involved in the study. Thus, fear of humans may alter the entire food chain.
“Humans are the most significant source of death for pumas in this population even though the cats are not legally hunted for food or sport,” Smith says. “Many are hunted illegally, struck by vehicles or legally killed by governmental agencies as a means of protecting livestock. So they have good reason to be fearful of us,” she adds. Darimont predicts other large carnivores would show similar responses because humans have effectively become the planet’s top predator---even if we often do not eat what we kill.
1.How did researchers make the discovery?
A. By fitting GPS collars to the animals’ prey and following them.
B. By getting to the kill sties and broadcasting all types of sounds.
C. By observing pumas’ reaction to frogs’ croaking or humans’ voices.
D. By counting how long pumas spent eating in different backgrounds.
2.According to the passage, humans’ presence will lead to ______.

C. pumas occupying less populated areas D. more puma feeding times within a day
3.Smith’s attitude towards the government hunting pumas is ______.
A. doubtful B. disapproving C. disappointing D. objective
