1 . We’ve all been there: in a lift, in line at the bank or on an airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.
What’s the problem? It’s possible that we all have compromised conversational intelligence. It’s more likely that none of us start a conversation because it’s awkward and challenging, or we think it’s annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it’s an invaluable social practice that results in big benefits.
Dismissing small talk as unimportant is easy, but we can’t forget that deep relationships wouldn’t
even exist if it weren’t for casual conversation. Small talk is the grease(润滑剂) for social communication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. ＂Almost every great love story and each big business deal begins with small talk,＂ he explains. ＂The key to successful small talk is learning how to connect with others, not just communicate with them.＂
In a 2014 study, Elizabeth Dunn, associate professor of psychology at UBC, invited people on their way into a coffee shop. One group was asked to seek out an interaction(互动) with its waiter; the other, to speak only when necessary. The results showed that those who chatted with their server reported significantly higher positive feelings and a better coffee shop experience. ＂It’s not that talking to the waiter is better than talking to your husband,＂ says Dunn. ＂But interactions with peripheral(边缘的) members of our social network matter for our well-being also.＂
Dunn believes that people who reach out to strangers feel a significantly greater sense of belonging, a bond with others. Carducci believes developing such a sense of belonging starts with small talk. ＂Small talk is the basis of good manners,＂ he says.

3 . Albert Einstein’s 1915 masterpiece “The Foundation of the General Theory of Relativity” is the first and still the best introduction to the subject, and I recommend it as such to students. But it probably wouldn’t be publishable in a scientific journal today.
Why not? After all, it would pass with flying colours the tests of correctness and significance. And while popular belief holds that the paper was incomprehensible to its first readers, in fact many papers in theoretical physics are much more difficult.
As the physicist Richard Feynman wrote, “There was a time when the newspapers said that only 12 men understood the theory of relativity. I do believe there might have been a time when only one man did, because he was the only guy who caught on, before he wrote his paper. But after people read the paper a lot understood the theory of relativity in some way or other, certainly more than 12.”
No, the problem is its style. It starts with a leisurely philosophical discussion of space and time and then continues with an exposition of known mathematics. Those two sections, which would be considered extraneous today, take up half the paper. Worse, there are zero citations of previous scientists’ work, nor are there any graphics. Those features might make a paper not even get past the first editors.
A similar process of professionalization has transformed other parts of the scientific landscape. Requests for research time at major observatories or national laboratories are more rigidly structured. And anything involving work with human subjects, or putting instruments in space, involves piles of paperwork.
We see it also in the Regeneron Science Talent Search, the Nobel Prize of high school science competitions. In the early decades of its 78-year history, the winning projects were usually the sort of clever but naive, amateurish efforts one might expect of talented beginners working on their own. Today, polished work coming out of internships(实习) at established laboratories is the norm.
These professionalizing tendencies are a natural consequence of the explosive growth of modern science. Standardization and system make it easier to manage the rapid flow of papers, applications and people. But there are serious downsides. A lot of unproductive effort goes into jumping through bureaucratic hoops(繁文缛节), and outsiders face entry barriers at every turn.
Of course, Einstein would have found his way to meeting modern standards and publishing his results. Its scientific core wouldn’t have changed, but the paper might not be the same taste to read.

4 . My best friend traveled to stay with our family last weekend. When she arrived, she went straight to the kitchen and, without asking, ate a spoonful of raspberry jam and some dried fruit. She wasn’t being rude. I knew she would do this. We’ve known each other for almost 20 years. She can eat anything she wants from my kitchen. Indeed, I bought her favorite fruits and snacks at the shop that morning.
Our long weekend together was luxuriously (惬意地) simple. I was recovering from surgery (手术) and couldn’t go to shopping malls. We passed the time running errands (做杂事), going to the post office and collecting dry cleaning. We drank way too many cappuccinos. But we talked about every little detail of our lives.
There’s never been a quiet moment in our friendship. We’ve lived in different cities for almost a decade. Reunions demand constant conversation. our personalities are matched, to be sure, and a shared history is indescribably valuable. We were competitors in high school before bonding over a bad experience. Then we discovered the many interests that we had in common. Our friendship cemented (巩固) itself quickly. We stayed companions through law school, through our first jobs and our first boyfriends. We supported each other through break-ups and breakthroughs. Ours is a friendship for the ages.
There is something special about friends who know everyone and everything about you. They are rare. These are the people you’ve chosen to witness your life. They have seen the bright lights of achievement, the depths of despair (绝望) and the boring routine (平淡乏味) of the in-between.
It’s special to unpack feelings and frustrations without wasting time filling in the blanks. As my long weekend shows, with such friends we don’t have to “do”, we simply have to “be”. We drop the act, the performance, the public version of ourselves.
The special friendships are those which never fail to delight, the continuation of which is worth the extra effort, despite distance and difference sneaking (溜进) into your separate lives. I had the very great joy of this reminder last weekend. I’m lucky to have found this friend, to see a future where her companionship remains. Being together is perfection.

5 . The history of microbiology begins with Dutch cloth maker named Antoni van Leeuwenhoek, a man of no formal scientific education. In the late 1600s. Leeuwenhoek, inspired by the magnifying lenses（放大镜）he used to examine cloth, built some of the first-microscopes. He developed technique to improve the quality of tiny, rounded lenses, some of which could magnify an object up to 270 times. After removing some plaque from between his teeth and examining it under a lens, Leeuwenhoek found tiny twisting creatures, which he called “animalcules”.
His observations, which he reported to the Royal Society of London, are among the first descriptions of microbes（微生物）. Leeuwenhoek discovered an entire universe invisible to the human eye. He found different microbes in samples of pond water, rain water, and human blood. He gave the first description of red blood cells, observed plant tissue, examined muscle, and investigated the life cycle of insects.
Nearly two hundred years later, Leeuwenhock’s discovery of microbes helped French chemist and biologist Louis Pasteur to develop his “theory of disease”. This concept suggested that disease originates from tiny organisms attacking and weakening the body. Pasteur’s theory later helped doctors to fight infectious diseases including anthrax, diphtheria, polio, smallpox, tetanus, and typhoid. All these breakthroughs were the result of Leeuwenhoek’s original work. Leeuwenhoek did not foresee this legacy.
In a 1716 letter, he described his contribution to science this way: “My work, which I’ve done for a long time, was not pursued in order to gain the praise I now enjoy, but chiefly from a strong desire for knowledge, which I notice resides in me more than in most other men. And therefore; whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, so that the scientific community might be informed thereof.”

6 . Modern medicine’s ability to keep us alive makes it tempting to think human evolution may have stopped. But if we look at the rate of our DNA’s evolution, we can see that human evolution hasn’t stopped – it may even be happening faster than before.
Evolution is a gradual change to the DNA of a species over many generations. It can occur by natural selection, when certain traits created by genetic changes help an organism survive or reproduce. Such genes are thus more likely to be passed on to the next generation, so they increase in frequency in a population. Gradually, these changes and their associated traits become more common among the whole group.
By looking at global studies of our DNA, we can see evidence that natural selection has recently made changes and continues to do so. Though modern healthcare disrupts a key driving force of evolution by keeping some people alive longer, in countries without access to good healthcare, populations are continuing to evolve. Survivors of infectious disease outbreaks drive natural selection by giving their genetic resistance to offspring. Our DNA shows evidence for recent selection for resistance of killer diseases like Lassa fever and malaria. Selection in response to malaria remains in regions where the disease remains common.
Humans are also adapting to their environment. Gene change allowing humans to live at high altitudes have become more common in populations in Tibet, Ethiopia, and the Andes. The spread of genetic changes in Tibet is possibly the fastest evolutionary change in humans, occurring over the past 3,000 years. This rapid increase in frequency of a mutated gene that increases blood oxygen content gives locals a survival advantage in higher altitudes, resulting in more surviving children.
Diet is another source for adaptations. Studies show that natural selection favoring a change allowing adults to produce lactase – the enzyme (酶) that breaks down milk sugars – is why some groups of people can digest milk. Over 80 per cent of northwest Europeans can, but in parts of East Asia, where milk is much less commonly drunk, an inability to digest lactose is the norm. Like high altitude adaptation, selection to digest milk has evolved more than once in humans and may be the strongest kind of recent selection.
Yet, despite these changes, natural selection only affects about 8 per cent of our genome. But scientists can’t explain why some genes are evolving much faster than others. We measure the speed of gene evolution by comparing human DNA with that of other species. One fast-evolving gene is human accelerated region 1 (HAR1), which is needed during brain development. A random section of human DNA is on average more than 98 per cent identical to the chimp comparator, but HAR1 is so fast evolving that it’s only around 85 per cent similar. Though scientists can see these changes are happening – and how quickly – we still don’t fully understand why fast evolution happens to some genes but not others.

7 . We all experience “oh crap” moments. Running into the person you canceled a date with — while you’re on another date. Realizing you hit “reply all”on an e-mail that you’d do anything to have back. Whatever the situation, the first thing you probably do is freak out. Everybody does.
While many of us think that we’re cool in a crisis, science tells us that we seldom are. At the moment we need to be keenly aware of our surroundings, our attention can tunnel in on the scariest thing in the scene, leaving us unaware of the other sights, sounds, and even smells around us. Armed robbers go unidentified because witnesses remember little more than the guns. Our ability to remember the things we do notice also becomes compromised; we can be told something, and two seconds later we’ll forget. And we jump to conclusions. When we’re freaked out, we’re anything but at our best.
These normal human reactions can be reversed. Once you calm down, you’ll face the most routinely ignored challenge of any crisis situation — identifying what the crisis is really about. We tend to misdiagnose problems because we don’t practice for them. Do the thinking ahead of time so you can just find the solution when it’s showtime. This is why flight attendants suggest you find the closest exit before you depart — so you don’t have to go exit shopping after the plane has caught fire or is sinking into a river.
Performing in a crisis is becoming more important for all of us, for two reasons. Back in the good old days, the reliability of most anything we used or did was far less than it is today. Now think about what happens to our preparedness as the possibility of something bad happening shrinks. Unless we practice what hardly ever happens, our ability to respond when it does happen tends to slip away. Reliability can kill you. Also, the systems we use today are more complex. There are seldom moving parts in plain view that allow us to see when things are about to go wrong. When complex systems lack transparency (透明度,显而易见), serious situations can “come out of nowhere.” We should all learn to breathe, recognize the situation, and carry out the plan that we were smart enough to prepare well in advance.
1. What does the underlined phrase “freak out” mean?| A．Be at one’s best. | B．Calm down gradually. |
| C．Run away immediately. | D．Panic or be scared. |
| A．Because the witnesses jump to conclusions. |

| A．Because of less reliability and less complexity. |
| B．Because of more reliability and more complexity. |
| C．Because of worse transparency and less preparedness. |
| D．Because of better transparency and more preparedness. |

| B．Staying cool and ignoring the challenge. |
| C．Calming down and remembering the situation. |
| D．Performing escaping and rescuing beforehand. |
8 . It’s late in the evening, time to close the book and turn off the computer. You’re done for the day. What you may not realize, however, is that the learning process actually continues in your dreams.
It might sound like science fiction, but researchers are increasingly focusing on the relationship between the knowledge and skills our brains absorb during the day and the often strange imaginings they generate at night. Scientists have found that dreaming about a task we’ve learned improves performance in that activity (suggesting that there’s some truth to the popular idea that we’re “getting” a foreign language once we begin dreaming in it). What’s more, dreaming may be an essential part of understanding, organizing and retaining what we learn.
While we sleep, research indicates, the brain replays the patterns of activity it experienced during waking hours, allowing us to enter what one psychologist calls a neural (神经的) virtual reality. A vivid example of such replay can be seen in a video researchers made recently about sleep disorders. They taught a series of dance moves to patients suffering from sleepwalking and related conditions. They then videotaped the subjects as they slept. Lying in bed, eyes closed, one female patient on the tape performs the dance moves she learned earlier.
This shows that while our bodies are at rest, our brains are drawing what’s important from the information and events we’ve recently encountered, then integrating that material into the vast store of what we already know. In a 2010 study, researchers reported that college students who dreamed about a computer maze (迷宫) task they had learned showed a 10-fold improvement in their ability to find their way through the maze compared with participants who did not dream about the task.
That study’s chief researcher Herbert Smith suggested that studying right before bedtime or taking a nap following a study session in the afternoon might increase the probability of dreaming about the material. Think about that as you go to sleep tonight.

A few years ago, my mom went to the doctor to ask him about her neck, which had been a little bigger than usual． It turned out there was something t wrong with her lymph glands (淋巴结), and soon they scheduled Mom to have a biopsy (组织切片检查) on the seventh of September．
As soon as I found out, I was very angry, as September 7 is my birthday．They had promised to take me to see a spider- man movie and had a picnic in the yard．I shouted at her and everyone else, too． I even shouted at the dog． I started begging her to reschedule the biopsy, She gave me this look like she was about to cry and said, “I’m sorry, but I’ve done everything I can. I’ve got a disease. Could you forgive me?” Finally, I just yelled, “ I hate you!” and ran into my room, crying． I sat on my bed thinking —Why do things always have to happen to me? Everyone gets diseases． Why couldn’t mom just go to hospital another day?
For the next couple of weeks 1 remained silently angry． Deep down I knew 1 shouldn't act that way, but I did anyway． Anyone could see how sad I was making my mom． I knew it wasn't her fault, but I had to have someone to blame．
Finally, my birthday came． My parents left early in the morning for the hospital, and I was sent to our neighbor's house． No spider-man movie, no birthday present, and no picnic． Though I was taken good care of, I was not having a good time． “This isn't fair,” I thought． “This was supposed to be my day．”
My parents came home late that night． Mom walked in with a bandage on her neck． She sat down and rested her head on my dad's shoulder． It hurt so badly that it was difficult for her to talk．

Sarah lived in a big family—four children with three sisters older than her. Father worked hard on the farm all day long to support the family. They had to save every penny to make ends meet.
One winter morning in March, Sarah put on her old spring coat to go out and play. “These buttons don't work,” Sarah said lo Mama. Just then, Mama noticed that this coat was too small for Sarah, She promised Sarah that after her sisters left for school, she would check the hand-me-downs (旧衣) for a coat that fit.
When the house was quiet. Mama went to the hall closet and pulled out all the old spring coats. But she could not find a suitable one for Sarah—Sylvia’s were too big, Susan’s too spotted, and Sally's too ragged. The coats were fine far play. But Sarah had no coat for church and (own and special occasions. Mama told it to Papa when he came in from the bam (布棚), after feeding the cows.
Papa sat down at the table. “Are you sure Sarah can't wear a hand-me-down?” he said. “It's either a new coat or a ragged coat,” Mama said. Papa frowned, staring out at the front yard. “Sarah has never had a new coat,” Mama added.
For a long while, nobody spoke. The fire in the wood stove crackled (发出劈啪声). Sarah looked closely at Papa. Then Papa cleared his throat. “A ragged coat won't do,” he said. “Sarah，are you old enough to lake care of a new coat?” “Yes, Papa,“ Sarah said, "I'm old enough to do almost anything.” Papa gave her a serious look. “Very well,” he said. “While we are in town today, we'll buy you a coat of your very own.” After they had eaten the soup, they headed for town in Papa's old truck.
