Whether you've gone away to college, moved to a new city or even just traveled for vacation.
Whether you've gone away to college, moved to a new city or even just traveled for vacation, homesickness is a common emotional experience. But what exactly are we feeling when we experience homesickness, why do we feel it so deeply, and why does it sometimes affect us physically?
“Homesickness has everything to do with attachment (依恋)," said Joshua Kiapow, a physically and emotionally," he explained. "We're longing for something that in our minds is known, predictable, consistent and stable."
Of course, different people experience homesickness in different ways. Kiapow said homesickness often causes physical changes in our bodies. "You feel it in your stomach — it' s an unease in which you feel uncomfortable, nervous, anxious, stressed, or tense because you're in a place or situation that's not familiar, that triggers (触发) your "fight-or-flight" response (“战或逃”反应), he said. "It's an evolutionary (进化的), adaptive thing that wires us to protect ourselves from danger when something is unknown. When we think about home, we know that the sense of unknown and potential danger is not happening there, so we want to return."
Meanwhile, longing and sadness also play a big part in feeling homesick. "The comfort of home becomes like a person you've lost and miss," said Kiapow. "You may have some (memories) about home and what you're missing, comparing everything in your day to your experience back home, and that can create a lot of sadness."
So what's the best way to fight homesickness? According to Klapow, keeping yourself busy with activities like schoolwork is a good way to keep your mind focused on other things. "When you're doing an activity, it distracts you, but you're also creating a new reality for yourself," he said. And, most importantly, sharing your feelings with others who are going through the same thing as you are means you have a support network. "Once you feel compassion (同情) from other people in the same place, you tend to feel less homesick," as Klapow said.

【推荐1】Every tropical (热带的) forest looks different, particularly in the eyes of an ecologist, and Peter Ellis has been lucky enough to visit a fair few. One in particular holds a special place in his heart: the rain forests of Gabon. He first visited as a Peace Corps volunteer. “It completely changed the way I think about conservation and our relationship with nature,” he says.
These days, Ellis is the global director of natural climate solutions science at the US-based conservation organization — The Nature Conservancy, where he’s presently investigating the role that logging (cutting down trees) can play in tropical forests. Logging for forest conservation may sound contradictory, and it often is. But logging in a tropical forest looks different to the practices we might expect to see. “We might imagine it as a wasteland of stumps (树桩) after a clear cut,” says Ellis. Instead, only a few trees are actually removed. A sustainably logged forest is the one that remains a breathing, rich, tropical rain forest full of trees and wildlife, thus helping keep a large part of the biodiversity while ensuring that more damaging industries don’t take its place. It can also provide a means of basic livelihood for the local people.
The two years that Ellis spent in the Gabon rain forests opened his eyes to a different method of land management. “The locals took me out into the forest and taught me the names, usages and spiritual significance of all the trees and other plants in the forest,” he says. “Science is about exact, designed experiments, but it’s also about asking the right questions. And the people who live in those places and protect the ecosystem are more likely to help us learn what the right questions to ask are.”
Tropical forests are essential to our planet’s future as they support high levels of biodiversity and act as crucial carbon sinks (碳储存器). “We need to honour, and protect them so that they can do their job to help save us all” says Ellis.

【推荐2】The universal speed limit of any kind of wave — whether electromagnetic or gravitational travelling through a vacuum has been known since Albert Einstein developed his theory of special relativity in 1905. But the maximum speed of sound moving through a solid or a liquid has just been calculated for the first time. It is about 36 kilometre per second, more than 8,000 times lower than the speed of light in a vacuum.
To make this calculation, Kostya Trachenko at Queen Mary University of London and his colleagues started with two well-known physical constants: the ratio of proton mass to electron mass, and the fine structure constant, which characteristics the strength of interactions between charged particles.
Trachenko says we have a pretty good idea of these values, because if they were changed even a bit, the universe wouldn’t look at all like it does.” If you change these constants by a few percent, then the proton might not be stable anymore, and you might not even have the processes in stars resulting in the combination of heavy elements, so there would be no carbon, no life,” he says.
Sound is a wave that spreads by making neighbouring particles interact with one another, so its speed depends on the density of a material and how the atoms within it are bound together. Atoms can only move so quickly, and the speed of sound is limited by that movement.
“The common wisdom was that diamond has the highest speed of sound, because it is the hardest material, but we didn’t know whether there was a theoretical fundamental limit to it,” says Trachenko. The theoretical bound is about twice the speed of sound in a diamond.
The speed of sound is also dependent on the mass of the atoms in the material, so there searchers predicted that solid metallic hydrogen — a material that theoretically exists at the centre of giant planets, but for which laboratory evidence has been hotly questioned — should have the highest speed of sound. They calculated that it should be close to the theoretical limit. They also looked at experimental data for 133 materials and found that none of them broke the limit.

【推荐3】Most parents can remember the artful mix of excitement and anxiety accompanying the choice of their baby’s name—it will follow the child his or her entire life. But the effect could be even more significant. In research recently published in the Journal of Personality and Social Psychology, our research team shows that the stereotype (模式思维) that a given society has of a first name can influence the way people look.
In eight studies, we found that participants shown ID-style photos of people they’d never met were able to recognize the first name of the described person well above the chance level. In other words, there is something about an Emily that…just looks like an Emily.
If an Emily really does look like an Emily, even a computer should be able to guess her true name. The computer was even able to produce a “heat map” for each name, a face with the features that “betray” a person carrying that name shown in red or orange colors. How should we understand this effect? Until now, social psychologists knew that our facial appearance influences the extent to which others perceive us as attractive, intelligent, trustworthy or warm. These studies show that others’ perceptions of our first name are reflected in our faces.
Interestingly, the face -name effect occurs even if we can only see the hair of a person. Our hair is possibly the part of our face that we control with the most ease. The fact that this alone can produce the face name effect further illustrates the suspected self-fulfilling mechanism behind it.
Together, the eight studies suggest that we wear our social belonging on our face, and that we actively shape our features to be recognized by our reference group. Choosing baby names remains exciting. Whatever the first name you give to your child, he or she will end up wearing it.

【推荐1】I know a lot of people have the urge to stick their head in the sand and pretend this could never happen to them. “But all that does is leave us open to not being prepared,” Dr. Abigail Hardin, a rehabilitation (复原) psychologist said. And that is exactly the last thing Dr. Abigail Hardin wants to see during this epidemic.
“Our brains do not function well under great stress. And when it's time to go to the hospital, you're going to be under immense stress. So it's much smarter to prepare in advance,” Hardin said, which is why Hardin says she was motivated to write “The COVID—19 Survival Guide: How to Prepare for, Manage, and Overcome a Coronavirus Infection.”
Hardin's first steps for accomplishing this? Taking continuous health precautions and creating a COVID—19 preparedness kit. "The preparedness kit is an equal to the medical kit that you put in the trunk of your car as an emergency kit," Hardin said. “Women who are pregnant often pack a kit to go to the hospital to give birth. This is the same.”
Hardin says most items in the kit are things we already know to pack in case of emergency. But it also includes important documents such as powers of attorney (授权书) and wills—documents that the National Institute on Aging recommend preparing in advance of a medical emergency. It includes things like an advanced directive or living will. Those will really help the care team provide care for us in a way that will improve the recovery process.
Hardin's book also goes over the list of care providers you could meet if hospitalized with the virus, including lead physicians, specialists, nurses and therapists. “I think there're larger problems here that we as a health care system need to address and one of them is making sure that in the future, when something like this happens, we do have psychologists available everywhere because no one deserves to go through this alone," Hardin said.
1. What's Hardin's attitude towards many people's view on COVID—19?A.Worried. | B.Skeptical. | C.Approving. | D.Indifferent. |
A.To share how to reduce stress. |

In Japan, a new social media campaign highlights the issues many women have with this footwear.
“
As early as January, Ishikawa shared her frustration about the unfairness of this dress code on the Instagram social network. In her part-time job as a funeral usher(迎宾员), she was required to wear black heels between 5 and 7cm high.
It’s a modest dream. Not too long ago, Japanese businessmen were expected to wear neckties, even on hot days. Then, the government encouraged companies to use less air conditioning and reduce electricity use. Men were freed from neckties. “This petition is the first step toward ‘creating a working environment free from unnecessary burdens’.” Ishikawa said.

【推荐1】Did you ever notice how your favorite clothes lose their color and seem thinner with time? Washing may be to blame.
According to a new study, clothes lose fewer dyes(染料) and fibers when washed in shorter cycles and in cool water. That means they will fade and thin less. These wash settings are greener, too—good for the environment.
As clothes are being washed in a washing machine, some of the fabric’s fibers loosen and are washed away. Clothes also lose some of dyes that colored them and the dyes and fibers lost in the water will end up in the environment.
“There is some sort of environmental impact as to almost everything you do,” says Lucy Cotton from the University of Leeds. Her research team put together two batches of clothes for tests. One had dark-colored T-shirts. The other had shirts in lighter colors. The team washed each batch in the same machine but used two different cycles. The first cycle lasted 30 minutes and used 25°C water. The second cycle used 40°C water and ran for 85 minutes.
After each cycle, the team collected fibers in the wash water and from an extra empty wash cycle afterward. They found that all shirts lost more color when washed in hot water in the longer cycle. Room-temperature water released fewer dyes than the hotter water did. The shirts also lost more tiny fibers in the longer, hotter cycle. Those microfibers matter because they give fabric its weight and strength. When the fabric loses too many microfibers, it will thin and weaken. Those microfibers will also pollute waterways.
And, just as microfibers add up to tons of waste, even small steps to cut waste will also add up. “Everything that you can do can make a difference,” Cotton says, “even if it is something as simple as changing your wash settings.”

【推荐2】These days,American children usually can receive about$800 each year in tips,according to the American Institute of Public Accountants. Most of American parents tie the tips to the completion of certain daily work.
“Kids are tipped for two main purposes,”says Steven Mintz,a historian at the University of Texas at Austin.“First,to give them a sense of independence—to buy candies,cheap toys,and other inexpensive products for themselves—and second,to teach them the value of money.”
However,many experts expressed concern that tying payments too closely to daily work can send kids wrong messages about family and personal responsibility. Suniya Luthar,a psychologist at Arizona State University,is doubtful of the idea of paying kids on a per-work basis.“Should we pay a child when he picks up his clothes off the floor?”she asks.
Luthar is not opposed to(反对) giving tips, but she thinks it’s important to let children know that certain work has to be done not because it’ll lead to payment,but because it’s part of what you have to do for yourself or as a family member. “In a family, no one’s going to pay you to put your clothes away or tidy up the house,” Luthar says.
Other researchers disagree.Heather Beth Johnson,a sociologist at Lehigh University,says,“When we pay kids to do things that humans have always had to do,”she says,“it sends them a message that they have to work for returns.”
Johnson adds that upper-middle-class families are usually ready to pay children for things like doing well in school or taking care of the younger children.She says that this sort of tips can make kids happier to carry out more basic responsibilities.“This isn’t happening in poor families,”she adds.

【推荐3】American and British people both speak English of course. But sometimes it does not seem like the same language. In fact, there are some important differences between British English and American English.
First of all, they sound very different. Often, Americans don’t say each word separately. They say several words together. Americans may say “I dunno” instead of “I don’t know.” Or they may say “Whaddya say?” instead of “What did you say?” However, the British are more careful in their speech. They usually say all the words and keep them separate.
Also, some letters have different sounds. For example, the Americans say the “a” in half like the “a” in cat. But the British say the “a” in half like the “o” in soft. Sound is not only the difference between British English and American English. Words sometimes have different meanings too. Some American words are never used in England. The same thing is true of some British words in America. For example, the vocabulary for cars and driving is very different. Americans drive trucks, but in England people drive lorries.
Many expressions are also different in the two countries. In England, if you are going to telephone your friends, you “phone them up”. In America, you “give them a call”. When you are saying goodbye in England you might say “Cheerio!”In America you might say “See you later.”
There’re also some differences in grammar. For example, Americans usually use the helping verb “do” when they ask a question. They say “Do you have a storybook?” But the British often leave out the helping verb. They say “Have you a storybook?”
All these differences can be confusing if you are learning English. But most languages are like this. Languages change over time. When people live in separate places, the languages change in different ways. This is what has happened to English. It can also happen to other languages, such as French. Many people in Canada speak French but their French is very different from the French of France.
