1 . Children born in the past four decades had the luxury of being the center of their parents’ attention. The entire family’s resources were poured into their education and well-being.
However，when the same resources are split between two children，the amount distributed to each one is going to shrink.
According to the Hangzhou Daily，when there are two children in the family，parents tend to choose public schools instead of private schools，which are usually more expensive. Each child is enrolled in fewer after-school training classes.
But having a second child may cure some deep-rooted problems in China’s traditional family education.
Having two children in the family can help to prevent one child being spoiled by too much attention，according to People’s Daily. It also spares the only child from the pressure of shouldering parental expectations all alone. Taking care of a sibling also enables children to gain a sense of responsibility，cooperation，obedience and caring.
China’s public education system is also expected to shift. Currently，there are not enough vacancies in kindergarten and schools to accommodate the potential increase in children.
“It’s not only the enrollment capacity of educational institutions that will feel the pressure. People are also placing more emphasis on the quality of education，”Peng Xizhe， director of the Population and Development Research Policy Center at Fudan University，told China Education Daily.
He predicts the government may have to invest more to support the educational system as a result of the new family planning measure.

2 . Some people must carefully pay attention to everything they put in their mouths in order to control their weight. By contrast, others can eat French fries to their hearts' content and achieve the same result. How do some people manage never to gain weight?
"Perception, one of the most important factors, has nothing to do with the body type because our personal feeling is always wrong. We often feel that some people who eat more don't put on weight. Actually? those who appear to eat whatever they like without gaining weight aren't eating more than the rest of us," said professor Kathleen Melanson. "For example, your friend who eats ice cream on a daily basis might eat less at another meal- or snack less throughout the rest of the day.”
“Physical activity can also make a difference, but it doesn't have to be a gym workout. There's little evidence to suggest that—without exercise-some people were born to burn significantly more calories than others," said Dr Ines Barroso, a researcher at the University of Cambridge. But there may be physical differences that allow some people to naturally control the number of calories they consume without exercising much self-regulation.
A lot of nervous system signals and hormones （激素）that circulate in our blood interact to tell us when we're hungry or full. This is called the appetite regulatory system, and it may be more sensitive in some people than others, Melanson said. One important hormone involved in this system is leptin （瘦素）.It helps regulate how much food we want to eat over longer periods of time, not just for our next meal. So a person with a more sensitive system might go back for seconds and thirds at a party, then feel full for the next few days and eat less.
Genetics can also play a role in a person's tendency to gain or lose weight. Researchers have identified over 250 different regions of DNA that are associated with obesity, according to a 2019 study published in PLOS Genetics.

3 . The death of soccer legend Diego Maradona has shocked fans worldwide and drawn an outpouring of grief. Maradona, 60, died of a heart attack on Nov 25,2020.
Argentina's president, Alberto Fernandez, declared three days of national mourning upon Maradona's death. "You took us to the top of the world," he wrote on the social networking platform Twitter, "and you were the greatest of Indeed, Maradona lived a life that showed that soccer at its peak can have passions that move entire nations. He was a man who was deified (奉若神明)in Argentina and the Italian city of Naples.
Maradona reached legendary position during the 1986 World Cup in Mexico after scoring two winning goals against England in the quarterfinal. That was a redemption (救赎)for the nation, which was defeated in a war over territory (领土)conflict by the UK just four years earlier. But his magic didn't stop there. At a time when teams were largely domestic, Maradona became the first truly global soccer superstar. Before his arrival in Napoli in 1984 they never won the Serie A title. The city took him in, regarding him as the man to bring back pride and respect to Naples. The club won the championship for the first time ever in the 1986-87 season.
Magician though Maradona may have been, he was deeply human, thus deeply flawed. He appeared in newspapers more for his drug habit than for his soccer skills in the late 1990s. After he played his goodbye game in 2001, Maradona stated, "The ball does not show the dirt."
As a symbol and idol he shone brighter than any other athlete in the last century. Argentina and Barcelona star Lionel Messi wrote, "He leaves us but does not leave, because Diego is eternal (不朽的)

4 . A strong coffee after a poor night's sleep is the kick-start many people need in the morning but new research suggests that it might be best to have a bite to eat first.
A study has found that drinking coffee first can have a negative effect on blood sugar control - a risk factor for diabetes （糖尿病）and heart disease.
“We know that nearly half of us will wake in the morning and, before doing anything else, drink coffee --- subjectively the more tired we feel, the stronger the coffee,“ said Professor James Betts, at the University of Bath in the UK.
For their study, researchers at the University of Bath got 29 healthy men and women to take part in three different overnight experiments, with at least a week between them.
In one, the participants had a normal night's sleep, roughly from 11 p.m. to 7 a.m., and were asked to consume a sugary drink on waking in the morning. They then experienced an interrupted night's sleep, where the researchers woke them every hour for five minutes by sending them text messages to which they had to respond — and upon waking were given the same sugary drink.
On another night, participants experienced the same sleep interruption, but this time were first given a strong black coffee 30 minutes before consuming the sugary drink.
They found that one night of interrupted sleep did not worsen the participants' blood sugar and insulin （胰 岛素）responses when compared to the normal night's sleep-- although previous research suggested that losing many hours of sleep or many nights of poor sleep could have a negative effect. However, strong black coffee consumed before breakfast actually increased the blood sugar response by around 50% — suggesting that relying on coffee after a bad night to stop feeling sleepy could limit your body's ability to tolerate the sugar in your breakfast.

5 . Honeybees can’t swim, and when their wings are wet, they can’t fly, either. But Chris Roh and other researchers at the California Institute of Technology found that when bees drop into bodies of water, they can use their wings to produce little waves and slide toward land—like surfers who create and then ride their own waves.
As with many scientific advances－Isaac Newton’s apple or Benjamin Franklin’s lightning bolt—Dr. Roh’s experiment began with a walk. Passing Caltech’s Millikan Pond in 2016, he observed a bee on the water’s surface producing waves. He wondered how an insect known for flight could push itself through water.
Dr. Roh and his co-worker, Morteza Gharib, used butterfly nets to collect local Pasadena honeybees and observed their surf-like movements. The researchers used a wire to restrict each bee’s bodily movement, allowing close examination of their wings. They found that the bee bends its wings at a 30-degree angle, pulling up water and producing a forward force. Bees get trapped on the surface because water is roughly three times heavier than air. But that weight helps to push the bee forward when its wings move quickly up and down. It’s a tough exercise for the bees, which the researchers guess could handle about 10 minutes of the activity.
The researchers said the surf-like movement hasn’t been documented in other insects and most semiaquatic insects use their legs for propulsion, which is known as water-walking. It may have evolved in bees, they predicted.
Dr. Roh and Dr. Gharib have imagined many practical applications for bees’ surfing. One plan is to use their observations to design robots able to travel across sky and sea. “This could be useful for search and rescues, or for getting samples of the surface of the ocean, if you can’t send a boat or helicopter,” Dr. Gharib said.

6 . Killer whales, or orcas, are known for their severe attacks on sea animals but they have never posed a threat to humans. However, since late July, the normally social animals have been intentionally attacking sailboats off the coasts of Spain and Portugal.
The strange behavior first surfaced on July 29, 2020, when a 46-foot boat was repeatedly attacked for almost an hour by nine orcas, causing the boat to rotate(旋转) 180 degrees and having its engine switched off. Since then, over 30 more similar incidents have been reported. On September 23, 2020, Spain's government banned boats of less than 50 feet in length from sailing in the 60-mile stretch of the Atlantic coastline between Ferrol and the Estaca de Bares Cape, where the attacks have been occurring.
Researchers across the world are trying to explain the orcas' behavior. Some believe it could be a result of the overfishing of the bluefish tuna - the orcas' primary food source -which has left the area's killer whales starving and unable to feed their babies. "I saw them look at boats carrying fish. I think they know humans are somehow related to food shortages, "says Ken Balcomb, senior scientist at the Center for Whale Research in Washington, USA. The environmentalists believe the sudden increase in boat traffic and fishing activities, after months of absence due to restrictions on human activity last spring, could also be contributing to the agitation.
However, Alfredo López, a biology professor in Galicia, Spain, thinks the attacks are defensive measures the orcas adopted to protect themselves against boat injuries. The researcher came to this conclusion after looking at the of the videos of a few incidents and noticing that two of the young killer whales involved had serious injuries. Hopefully, the experts will be able to find a way to restore the harmony between the animals and the humans soon.

7 . For much of human history and in many places, girls were considered property, or required to obey their fathers until the day they had to start obeying their husbands. In most of the world that vision of girlhood now seems not merely old-fashioned but unimaginably remote. In field after field girls have caught up with boys. Globally, young women now outnumber (数量超过) young men at university. Girl babies are more wanted than ever before. Even in places, such as China, where the sex-selective abortion of girls has been common, it is becoming less so. Girls are also less likely to be married off in childhood. In 1995 almost six in ten girls in South Asia were married before reaching 18; that has fallen by half.
When societies handle girlhood well, the knock-on effects are astonishing. A girl who finishes secondary school is less likely to become a child bride or a teenage mother. Education boosts earning power and widens choices, so she is less likely to be poor or to suffer domestic abuse. She will have fewer children, and invest more in them. They will be less likely to die in babyhood, or to grow up stunted physically or mentally. She will read to them more and help them with their homework. All this means they will learn more, and earn more as adults. A recent study estimated that, if 100% of their girls completing secondary school is ensured, it could lead to a lasting boost to GDP.
Despite the benefits of nurturing girls, some countries have still failed to grasp them. Only one girl in three south of the Sahara finishes her secondary education. The COVID-19 pandemic could disturb progress for girls in poor countries, or even reverse it. When Ebola forced west African schools to close in 2014, many girls dropped out, never went back and ended up pregnant or as child laborers. UNICEF warns that something similar could happen with COVID-19—but on a larger scale.

8 . On April 30. 2020, the world's most famous musicians met online to celebrate the tenth International Jazz Day. with the hope to revive jazz music and explore its possibility as a unifying voice across cultures.
Despite the celebrations, though, the jazz audience continues to grow older because the music has failed to attract the younger generations. It's their job to help change that.
Jason Moran, the Kennedy Center's artistic adviser for jazz, was one of the musicians. He hopes to widen the audience for jazz and make the music more accessible and enjoyable.
“Jazz seems like it's not really a part of the American appetite （胃 口）. " Moran tells National Public Radio's reporter Neal Conan. "I hope that the younger generations understand that jazz is not black anymore. It's actually colorful, and it's actually digital.
Moran says one of the problems with jazz today is that the fun side of the music has been lost. “Today, the music can't be presented the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same. " says Moran.
Last year, Moran worked on a project that arranged Fats Waller's music for a dance party, “I just wanted to put it back in the mind that Waller is dance music as much as it is concert music. says Moran. “For me, it's just to re — contextualize. Sometimes we lose sight that the music has a wider context. It can be adapted to（适应）different situations.
During the interview, he asked- "In music, where does the feeling lie? Are we, as humans, gaining any insight（感悟）on how to talk about ourselves and how a Fats Waller record gets us into a dialogue about our emotions and our thoughts?”
He added that most of the musicians have recognized the need and agreed to continue those dialogues for the year.

9 . A living, bio-degradable (可生物降解的) fabric named "Biogarmentry" has been invented.
Made from algae (藻) the textile (纺织品) purifies the air around it through photosynthesis (光合作用).
Researchers claim it’s the first living textile, and have fashioned the material into sheer, cloak-like garment. While prototypes (雏形) like these are still in the early stages of research and design, and far from mass production, they challenge the fashion industry to reimagine ways it can reduce its large carbon footprint through alternative fabrics.
Fashion is one of the world's most polluting industries. It's responsible for more carbon emissions than international flights and shipping combined, amounting to 10% of all greenhouse gasses emitted globally. The crops traditionally used to make clothing absorb carbon as they grow, but most natural materials are still carbon emitters. Take a single T-shirt made of cotton as an example. The estimated footprint of a cotton shirt over its lifetime is 15 kilograms (33 pounds) of carbon dioxide, with most of that emitted during the energy-intensive production and dyeing (染色) processes.
In recent years, environmental start-ups have proposed a number of alternative natural fibres, many Of which have the potential to sequester carbon but none have been shown to achieve zero emissions. As algae has the ability to trap carbon, a carbon-negative raincoat made of marine algae has been created. Algae-based materials are, currently, where electric vehicle technologies were a decade ago. The technology is now ready for prime time. When the resulting garments are commercially available, we can imagine people wearing their own organic cloak, spraying their organism as they go to work and encouraging their algae to purify the air.
1. What's the text mainly about?| A．A textile helping purify air. | B．An industry causing pollution. |
| C．A way to achieve zero-emission. | D．A trend in the fashion industry. |
| A．An international flight. | B．Clothing made of cotton. |
| C．A petrol-powered vehicle. | D．A raincoat made Of algae. |

10 . Besides the excitement of travel, one reason to study abroad is that you will experience new customs, holidays, foods, art music and politics firsthand.
“I learned the language and am now fluent, but perhaps more important was how much I learned about cultures, people and myself. I learned this from the viewpoint of an active member of the community and my host family , not from the tourists’ point of view，," said Andrew, who studied in Poitiers, France.
Another reason for studying abroad is that you'll gain self-confidence. Christina studied in Caracas, Venezuela, a city of 10 million people and a huge change from her hometown of 35,000! Christina says she learned how to better stand up for herself and her beliefs and to express herself in another language. What could make you more confident than that?
Living away from home can also help you adjust in the transition (过渡)to college and adulthood .Matthew says he returned from studying in Australia with confidence and a real interest in international affairs that really set him apart from his peers. "After having gone abroad in high school, I found the transition to college to be a breeze——moving 560 miles from home didn’t seem particularly frightening after having lived thousands of miles away.”
And speaking of college, improving your language skills might help you get into dream colleges and even land future jobs. Colleges and employers know that studying abroad provides leadership skills in a world that is increasingly globally interconnected.
Most of all, it's fun! You're not likely to suffer from general boredom while you're studying in a different learning environment.
