1 . Three scientists jointly won this year’s Nobel Prize in physics for proving that tiny particles (粒子) could keep a connection with each other even when separated, a phenomenon once doubted but now being explored for potential real-world applications such as encoding information. Frenchman Alain Aspect, American John F. Clauser and Austrian Anton Zeilinger were quoted by the Royal Swedish Academy of Sciences for experiments proving the “totally crazy” field of quantum entanglements (量子纠缠) to be all too real. They demonstrated that unseen particles, such as photons (光子) , can be linked, or “entangled”, with each other even when they are separated by large distances.
In quantum entanglement, establishing common information between two photons not near each other “allows us to do things like secret communication, in ways which weren’t possible to do before”, said David Haviland, chair of the Nobel Committee for Physics. Quantum information “has broad and potential effects in areas such as secure information transmission, quantum computing and sensing technology”. The kind of secure communication used by China’s Micius satellite, as well as by some banks, is a “success story of quantum entanglement”, said Harun Siljak of Trinity College Dublin.
The Nobel Committee said Clauser developed quantum theories first put forward in the 1960s into a practical experiment. Aspect was able to correct an error in those theories, while Zeilinger demonstrated a phenomenon called quantum teleportation that effectively allows information to be sent over distances. “Using entanglement you can send all the information which is carried by an object over to some other place where the object is.” Zeilinger said. He added that this only works for tiny particles. “It is not like in the Star Trek films transporting something, certainly not the person, over some distance,” he said.

4 . The traditional Chinese solar calendar divides a year into 24 solar terms. The Spring Equinox, the fourth term of the year, signals the equal length of the day and night time.
The ancient Chinese people divided the fifteen days of the Spring Equinox into three “hou’s,” or five-day parts. As the old saying goes, “swallows fly back to the North in the first hou; thunder cracks the sky in the second hou; lightning occurs frequently in the third hou.”
Standing an egg upright is a popular game across the country during the Spring Equinox. It is an old custom that dates back to 4,000 years ago.
In ancient times, people did not have good medical resources. So to pray for health, they wrote their medical issues on paper kite. When the kite was in the air, people would cut off the string to let the paper kite float away, symbolizing the flying away of diseases.
This practice is popular in the southern area of the lower reaches of the Yangtze River. As the Spring Equinox comes, farm work starts and both the farmers and the cattle start to become busy. Farmers will reward cattle with sticky rice balls to express their gratefulness.
A.Reward farm cattle |
B.Hold sacrifice ceremonies |

I grew up in the south of Arizona in a little community called Estepona. I was 16 when one morning, my father told me I could drive him into a remote village called Mijas, about 18 miles away, on condition that I take the car in to be serviced at a nearby garage. Having just learned to drive, and hardly ever having the opportunity to use the car, I readily accepted.
I drove Dad into Mijas and promised to pick him up at 4 P. M…Then I drove to a nearby garage and dropped off the car. Because I had a few hours to spare, I decided to catch a couple of movies at a theater near the garage. However, I became so immersed in the films that I completely lost track of time. When the last movie had finished, I looked down at my watch. It was six o’clock. I was two hours late!
I knew Dad would be angry if he found out I’d been watching movies. He’d never let me drive again. I decided to tell him that the car needed some repairs and that they had taken longer than had been expected. I drove up to the place where we had planned to meet and saw Dad waiting patiently on the corner. I apologized for being late and told him that I’d come as quickly as I could, but the car had needed some major repairs. I’ll never forget the look he gave me.
“I’m disappointed that you feel you have to lie to me, Jason.”
“What do you mean? I’m telling the truth.”
Dad looked at me again. “When you did not show up, I called the garage to ask if there were any problems, and they told me that you had not yet picked up the car. So you see, I know there were no problems with the car.”

Like almost every set of new parents, Bryan and Elizabeth Shaw started snapping pictures of their son, Noah, practically from the moment he was born. When he was about three months old, Elizabeth noticed something odd.
The flash on their digital camera created the typical red dot in the center of Noah’s left eye, but the right eye had a white spot at the center, almost as if the flash was being reflected back at the camera by something. When Elizabeth took Noah to an eye doctor, Noah was diagnosed with retinal (视网膜) cancer with the white reflection as a sign. He endured months of treatment, but it was too late.
Noah’s cancer is treatable if caught early. Bryan Shaw wondered whether there were signs he’d missed. He went back over every baby picture of Noah he could find and discovered the first white spot in a photo taken when Noah was 12 days old. As time went on, it appeared more frequently. “By the time he was four months old, it was showing up in 25percent of the pictures taken of him per month,” Bryan recalled.
Later, Bryan was determined to put his hard-won insights to good use. He created a database that recorded the cancer’s appearance in every photo of Noah. He also collected photos and compiled the data from eight other children with the same cancer. Armed with that data, he began to work with colleagues to develop a smartphone app that can scan the photos in the user’s camera roll to search for white eye and can be used as a kind of ophthalmoscope (眼底镜). Called White Eye Detector, it is now available for free on Google Play and in Apple’s Apple Store.
“I just kept telling myself, I really need to do this,” Bryan said. “This disease is tough to detect. Not only could this software save vision, but it can save lives.”

8 . Social media companies are often compared to tobacco companies, for they both market harmful products to children and design their products for maximum customer loyalty (that is, addiction), but there’s a big difference: Teens can and do choose, in large numbers, not to smoke. Social media, in contrast, applies a lot more pressure on non-users, at a much younger age and in a more unnoticed way.
Once a few students in any middle school open accounts at age 11 or 12, the pressure on everyone else to join becomes intense. Even a girl who consciously knows that Instagram can foster beauty obsession, anxiety, and eating disorders might sooner take those risks than accept the seeming certainty of being out of the picture and excluded. In this way, social media unlocks a remarkable achievement: It even harms adolescents who do not use it.
A recent study in the University of Chicago illustrated the effects of the social media trap precisely. The researchers asked more than 1,000 college students how much they would need to be paid to deactivate (停用) their accounts on Instagram for four weeks. On average, the students said they would need to be paid roughly $ 50. Then the experimenters told the students that they were going to get most of their friends to do the same, and then asked, Now how much would you have to be paid to deactivate, if most others did so? The answer, on average, was less than zero — most students were willing to pay to have that happen.
Most students are on social media only because everyone else is too. This is the textbook definition of what social scientists call a collective-action problem. It’s what happens when a group would be better off if everyone in the group took a particular action, but each actor is discouraged from acting, because unless the others do the same, the personal cost outweighs the benefit. Cigarettes trapped individual smokers with a biological addiction. Social media, however, has trapped an entire generation in a collective-action problem.

10 . There’s a site in Cornwall, in southern England, called Woodland Valley Farm. Here, farmer Chris Jones allows beavers (河狸) to wander in an enclosed five-acre plot. Their natural dams, he says, have helped control repeated flooding of the downstream village.
Centuries after beavers were hunted to extinction in Britain, efforts are now underway by environmentalists to reintroduce the creature. “Sometimes they can really be annoying; they can mess everything up,” says Christof Angst, an official consultant of be aver management. “But if you look at it on the whole, the positive impact of this species is huge.” Some of the benefits of beavers’ work on a landscape include a boost to biodiversity, drought resistance, and improvement of water quality by moving pollutants.
Yet, as the animals’ return becomes increasingly widespread, the debate is shifting from whether to bring them back to a question of how to manage them once they start appearing in waterways. The consequences of bringing beavers back are not all positive, the most common one being the flooding they can cause, rather than reduce. In addition, critics point to the high costs of beaver-felled trees and be aver reintroduction programs.“Who’s going to pick up the cost, who’s going to do the repairs, who’s going to cover crop loss?”asks Richard Bramley, a farmer from the York area.“There’s no plan.”
To avoid conflicts, organizers have fenced in beaver-related projects. The beavers are not permitted to wander freely beyond the fences. The government has also put together a beaver management strategy framework, which advises communication and listening, in an effort to clear up misunderstandings and concerns. When beavers do cause issues, available options will be provided, including modifying the dams, reducing water levels, or relocating the animals.
“What we want to direct people towards is coexistence with wildlife and nature,” saysEva Bishop, head of communications and education at the Beaver Trust. “We need to encourage people to give space for nature to function.”
