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.

1. When people are homesick, they may often feel changes in their__________.
A.heartB.headC.stomachD.lungs
2. What is the cause of homesickness according to Klapow?
A.Lack of self-control.B.Uncertainty about one's environment.
C.Longing for love.D.Pessimism about the future.
3. How does homesickness affect people?
A.It protects people from getting hurt.
B.It prevents people from exploring new environments.
C.It helps people to have a closer relationship with their family.
D.It brings about both physical and mental discomfort.
4. What does Klapow think is the best way to fight homesickness?
A.Communicating with people in the same situation.B.Making more friends through different activities.
C.Seeking help from doctors and specialists.D.Showing compassion for people around you.

文章大意:本文是一篇夹叙夹议文。主要介绍了Peter Ellis访问加蓬热带雨林的经历,这些经历使他重新审视自然保护以及人与自然的关系。

【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.

1. What does Peter Ellis think of his first visit to the rain forests of Gabon?
A.It was poorly arranged.B.It made little difference to his life.
C.It brought him far-reaching influence.D.It was physically challenging for him.
2. What does Peter Ellis realize after his investigation in tropical rain forests?
A.Logging balances the rain forests.
B.Logging means a complete clear-out.
C.Logging brings huge profits to the locals.
D.Logging encourages the local damaging industries.
3. What does Ellis suggest scientists do in protecting the rain forests?
A.Conduct many experiments.B.Consult experienced local people.
C.Get involved in designing procedures.D.Spread more knowledge about wildlife.
4. What is the purpose of the last paragraph?
A.To stress the importance of biodiversity.
B.To introduce Ellis’s ideas about the future.
C.To provide further information about Ellis.
D.To call on people to preserve tropical rain forests.

文章大意:本文是一篇说明文。文章讲述了对声音在固体和液体中传播速度的研究,以及声音在固体物质中的最高速度的探索。

【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.

1. How did people find out the speed of waves?
A.By measuring the speed of sounds.
B.By using modern technology and science.
C.By depending on a great scientist’s theory.
D.By comparing the theories about the universe.
2. What does the underlined word “they” in paragraph 3 refer to?
A.Interactions.B.Particles.C.Values.D.Constants.
3. What do Trachenko’s words indicate?
A.Diamond has surely the highest speed of sound.
B.He believes in a theoretical fundamental limit.
C.Solid and liquid materials have the same speed limits.
D.Diamond has yet to be proven the hardest material.
4. What conclusion can we get if there is solid metallic hydrogen?
A.It has a close theoretical fundamental limit of speed.
B.There would be no carbon,no life in the universe.
C.Some materials broke theoretical fundamental limit.
D.It will surely travel to other sections of the universe.

【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.

1. What was the participants’ assignment?
A.To pick out ID-style photos they’d never met.
B.To match strangers’ photos with their names.
C.To find out Emily from various ID photos.
D.To perceive Emily’s character.
2. How is the “heat map” formed?
A.By drawing a map for each name.
B.By sorting out different faces in a map.
C.By showing a person’s face in different colors.
D.By highlighting certain features in warm colors.
3. What is the face-name effect?
A.People wear their character on their faces.
B.Hairstyle accounts for a large part in appearance.
C.A fixed idea of first names determines one’s look.
D.Social belonging is irrelevant to our facial features.
4. Which of the following shows the structure of the whole text?
P=Paragraph
A.B.
C.D.
