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 don’t have enough conversational ability. It’s more likely that none of us start a conversation because it’s embarrassing 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 a valuable social practice that leads to big benefits.
It is easy to consider small talk as unimportant, but we can’t forget that deep relationships wouldn’t even exist (存在) if there weren’t casual conversations. 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 secret to successful small talk is learning how to connect with others, not just communicate with them.”
In a 2014 study, Elizabeth Dunn, professor of psychology at UBC, invited people to a coffee shop. One group was asked to interact with its waiter, the other, to speak only when necessary. The results showed that those who chatted with their server reported obviously 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 is important for our happiness and health.”
Dunn believes that people who reach out to strangers feel a greater sense of belonging, a link with others. Carducci believes developing such a sense of belonging starts with small talk. “Small talk is the basis of good manners,” he says.

2 . We often think about relationships on a scale from positive to negative. We are drawn to loving family members, caring classmates and supportive mentors. We do our best to avoid the cruel uncle, the playground bully and the jerk boss.
But the most harmful relationships aren’t the purely negative ones. They’re the ones that are a mix of positive and negative. We often call them frenemies, supposed friends who sometimes help you and sometimes hurt you. But it’s not just friends. It’s the in-laws who volunteer to watch your kids but devalue your parenting. The manager who praises your work but denies you a promotion.
Groundbreaking research led by the psychologists Bert Uchino and Julianne Holt-Lunstad shows that ambivalent (矛盾情绪的) relationships can be damaging to your health — even more than purely negative relationships.
Even a single ambivalent interaction can cause harm. In one experiment, people talked about controversial (具有争议性的) topics in front of a friend who offered feedback. The researchers had randomly assigned the friend to give ambivalent or negative comments. Receiving mixed feedback caused higher blood pressure than pure criticism. “I would have gone about the topic differently, but you’re doing fine” proved to be more distressing than “I totally disagree with everything you’ve said.”
The evidence that ambivalent relationships can be bad for us is obvious, but the reasons can be harder to read — just like the relationships themselves.
One reason is that ambivalent relationships are unpredictable. With a clear enemy, you put up a shield when you cross paths. With a frenemy, you never know whether Dr. Jekyll or Mr. Hyde is going to show up. Feeling unsure can break the body’s calming system and activate a fight-or-flight response. It’s unsettling to hope for a hug while also preparing for a likely quarrel.
Another factor is that unpleasant interactions are more painful in an ambivalent relationship. It’s more distressing to be let down by people you like sometimes than by people you dislike all the time. When someone stabs you in the back, it stings more if he’s been friendly to your face.

| C．Ambivalent Relationships are the most harmful. | D．Positive relationships are better than negative ones. |
3 . Tropical cyclones(热带气旋), including hurricanes and typhoons, are now moving at a slower speed than they did decades ago, new research shows.
While having a cyclone travel with less speed may seem like a good thing, it’s actually just the opposite. Wind speeds within the storm remain high, but the whole system itself moves slower, allowing punishing rains to stay longer over communities. “Nothing good comes out of a slowing storm,” says James Kossin, author of the paper. “It can increase the amount of time that buildings suffered from strong wind. And it increases rainfall.”
In his paper, Kossin showed that from 1949 to 2016, tropical cyclones across the globe slowed their movement by 10 percent on average. In some regions (地区), the speed of those storms slowed even more as they hit land. In the western North Pacific, the decrease was much more manifest—almost a third. That means a storm that may already hold more moisture (水分)will have time to drop more of it in each spot.
Kossin’s work was based on details of almost 70 years’ worth of storms, but he didn’t try to determine what was causing the slowdown. Still, the change is exactly what he and other cyclone experts said, which would be expected from climate change. With the polar regions warming faster than other parts of the globe, that is changing the pressure and reducing the winds that push these storms.
Christina Patricola, a scientist, called Kossin’s work important and new and said she found it reliable. “I was not surprised by his findings,” she says. “But I was surprised by the speed of the slowdown.”
Kossin hopes that scientists will begin building models that show which places are likely to face the most risk. Given that storms in some regions are moving towards polar regions and already increasing in intensity(强度), cyclones causing unusually powerful rain may threaten places not normally in their paths. Scientists must take action to make those places suffer less from the disasters.

| D．To call on scientists to focus on the danger of climate change. |
4 . In the late 1930s, people could donate blood, but very few hospitals could store it for later use. Whole blood breaks down quickly, and there were no methods at the time for safely preserving it. As a result, hospitals often did not have the appropriate blood type when patients needed it. Charles Drew, a Black surgeon and researcher, helped solve this monumental problem for medicine, earning him the title “Father of the Blood Bank.”
In 1938, while obtaining his doctorate in medicine, Drew became a fellow at Columbia University’s Presbyterian Hospital in New York. He studied the storage and distribution of blood, including the separation of its components, and applied his findings to an experimental blood bank at the hospital.
As Drew was finishing his degree at Columbia, World War II was erupting in Europe. Great Britain was asking the United States for desperately needed plasma (血浆) to help victims. Given his expertise, Drew was selected to be the medical director for the Blood for Britain campaign. Using Presbyterian Hospital’s blood bank as a model, Drew established uniform procedures and standards for collecting blood and processing blood plasma from nine New York hospitals. The five-month campaign collected donations from 15,000 Americans and was considered a success. His discoveries and his leadership saved countless lives.
With the increasing likelihood that the nation would be drawn into war, the United States wanted to capitalize on what Drew had learned from the campaign. He was appointed as the assistant director of a three-month pilot program to mass-produce dried plasma in New York, which became the model for the first Red Cross blood bank. His innovations for this program included mobile blood donation stations, later called bloodmobiles.

6 . Running and walking are both excellent forms of exercise. Those who regularly do either usually have healthier hearts, stronger bones and lower body weights than those who do little exercise. But does it matter whether you spend time walking or running? Arguments can be made for both, and which is right for you depends on your goals and your present fitness level.
“The key difference between running and walking is how many calories you are burning — not per mile, but per minute of exercise,” says Paul D. Thompson, a doctor at Hartford Hospital. “Running is a more efficient movement and it’s more demanding on the body, so it burns more calories per minute,” Thompson says. “But if you’ve got the time to walk long enough to burn the same amount of calories, then walking is fine.” That said, if your final goal is to lose weight, chances are that neither running nor walking alone is going to do the trick. Research has shown that it needs to be done along with calorie control.
In a recent study that analyzed data from nearly 50, 000 people, researchers found that runners’risk of heart disease was 4.5 percent lower than that of those who were inactive. But walkers who burned the same amount of calories daily had a risk level that was 9 percent lower than those who were inactive.
“Running gets the reputation for causing injuries because many people who are just starting to run try to do too much too quickly,” says Carol Ewing Garber, a professor at Columbia University. “And they often get injured as a result. If you want to progress from walking to running, do it slowly, gradually increasing your speed, distance and the frequency of your runs?”
Running may be more highly-intense and calorie-burning than walking, but walking is a great way to ease into exercise and make sure you are staying physically active every day. The bottom line is that getting exercise of any kind is beneficial — if you keep doing it.
“The best exercise is the one you are going to do,” Thompson says. “There are extra benefits to be gained from running, but what’s most important from a public health point of view is that everyone gets out and does some kind of exercise?”
1. What can we infer from Paragraph 2?| A．Walking is more demanding on the body. |
| B．Walking is better than running for busy people. |
| C．Running can reduce people’s fat quickly and safely. |
| D．Exercise on its own is not enough to lose weight. |

7 . Certain areas near the moon’s poles stay everlastingly in shadow, never receiving direct sunlight. Recent studies suggest these so-called permanently shadowed regions (PSRs) contain rich ice resource that could show details about the early solar system; they could also help future visitors make fuel and other resources. But these areas are hard to photograph from satellites moving around the moon and thus are a challenge to study. The few photos PSRs reflect are often flooded by camera noise and quantum effects (量子效应).
Now researchers have produced a deep-learning algorithm (算法) to cut through the interruption and to see these dark zones. “Our images enable scientists to identify the features of craters and boulders (陨石坑和巨石),” says Valentin Bickel, a planetary scientist at the Max Planck Institute of Solar System Research in Germany and lead author of a Nature Communications study testing the new algorithm.
The researchers used more than 70,000 images of completely dark lunar areas — with no light signal — together with details about the camera’s temperature and position in orbit to train their algorithm to recognize and remove camera noise. Next they dealt with the rest noise through information learned from millions of sunlit lunar photos, together with copied versions of the same images in shadow. Ignacio Lopez-Francos, a study co-author and engineer at the NASA Ames Research Center, says using such man-made shadow was necessary because sunlit PSR images do not exist. A similar technique is also used in low-light digital camera photography.
The researchers used their algorithm to analyze the size and number of craters and boulders in several PSRs that might be explored by NASA’s Artemis moon program. They also found the likely origins of some boulders and established a potential route for an astronaut through a PSR on the moon, avoiding obstacles and slopes steeper than 10 degrees.
“It’s an interesting application of machine-learning technology, and the noise model seems realistic and useful for this real case,” says computer scientist Chongyi Li, who uses similar strategies to enhance underwater images at Singapore’s Nanyang Technological University and was not involved in the study.

8 . Fiji is an island nation with mountains to climb, jungles to explore, vast reefs under the waves to dive, and beaches to walk on. You can go to the open-air souvenir markets to shop for authentic Fijian crafts (工艺品) like wooden kava bowls and visit the Fiji Museum. You can also attend Fire walking ceremony, the traditional practice of fire walking, where men walk barefoot across hot stones.
Best Time to Go
There is no bad time for Fiji vacations. However, November to April is the wet season, when temperatures and humidity (湿度) are higher and there is a greater risk of hurricanes. August and October are some of the most popular months to visit Fiji’s islands, but this also means you will have to deal with high-season crowds and prices. Brave the heavy but short downpours in the wet season if you want to escape the crowds and get some great deals.
Accommodation & Transport & Food
Some restaurants are expensive and attract the world’s rich and famous, but you can find much cheaper options with equally beautiful locations. Budget hotels start at around $30 a night for a double room with sea views.
If you don’t mind getting about on a bus, you will find this is a cheap and efficient form of transport. Traveling from Suva to Nadi, for example, costs around $25 for a four-hour trip.
You can eat for as little as 5insmallrestaurants, and mid—range restaurants start at around 15 for a meal. Many accommodation options include meals, so you can take full advantage of this to save some money.
All up, Fiji is a very reasonably priced destination with priceless experiences on offer. So, what are you waiting for?
1. What can tourists do in Fiji?| A．Witness a special ceremony. | B．Walk on hot stones with shoes. |
| C．Shop in large indoor souvenir markets. | D．Make wooden kava bowls by themselves. |

9 . While scientists have many ideas, they are not certain why humans yawn(打哈欠). Still, there is one thing experts know—yawns seem to be contagious(传染)!
Have you ever caught a yawn from someone else? Most people have. In fact, a person is six times more likely to yawn after seeing someone else do so. Experts have done many studies into why yawns seem to pass from person to person. As a result, they have a few theories(理论) for the reason behind it.
One possible explanation has something to do with social mirroring, which is caused by mirror neurons(镜像神经元) in the brain. These mirror neurons help the brain notice useful behavior of others and then copy it. When one person sees another yawn, his mirror neurons observe the action and consider it to be beneficial. That may cause him to yawn, too.
Another popular theory is that yawns are contagious because of social relationships. Being social creatures, humans form friendships, families and live together in groups. That’s why many people mirror others, such as smiling when another person smiles. Yawning may be just another example of this. In fact, research has shown that one is most likely to catch yawns from another person if the two share a social relationship.
The answer could even be that yawns aren’t truly contagious at all. Instead, people yawn together simply because they’re in the same environment. Experts say many things may cause yawning, including temperature and time of day. Whatever the explanation is, experts do know that contagious yawns aren’t limited to humans. One study found that lions in South Africa also caught each other’s yawns.

10 . When I was nine years old, I loved to go fishing with my dad. But the only thing that wasn’t very fun about it was that he could catch many fish while I couldn’t catch anything. I usually got pretty upset and kept asking him why. He always answered, “Son, if you want to catch a fish, you have to think like a fish.” I remember being even more upset then, because “I’m not a fish!” I didn’t know how to think like a fish. Besides, I reasoned, how could what I think influence what a fish does?
As I got a little older, I began to understand what my dad really meant. So, I read some books on fish. And I even joined the local fishing club and started attending the monthly meetings. I learned that a fish is a cold-blooded animal and therefore is very sensitive to water temperature. That is why fish prefer shallow water to deep water because the former is warmer. Besides, water is usually warmer in direct sunlight than in the shade. The more I understood fish, the more I became effective at finding and catching them.
When I grew up and entered the business world, I remember hearing my first boss say, “We all need to think like sales people.” But it didn’t completely make sense. My dad never once said, “If you want to catch a fish, you need to think like a fisherman.” What he said was, “You need to think like a fish.” Years later, with great efforts to promote long-term services to people much older and richer than me, I gradually learned what we all need is to think more like customers. It is not an easy job. I will show you how in the following chapters.
