In the competition of Olympic weightlifting, the athletes try to lift the maximum (最大的) weight they can. There are special conditions they have to meet in order to compete: body weight, height and strength.
The Olympic weightlifting mainly tests the limit of explosive strength (爆发力). There are not many lifters who really like Olympic weightlifting and the explanation is very simple: they are short of explosive strength.
The weights used for Olympic weightlifting are added in kilograms. The order by which the athletes enter the competition is not general, but it is set depending on the event. Usually the athlete with the lowest weight begins. If he/she is not successful, he/she can try later. There is a maximum of three lifts allowed for every competition.
For many years Olympic weightlifting was only for men. However, now women also take part in Olympic weightlifting. It was at the beginning of the 21st century that women’s competitions entered an organized professional environment. For women, Olympic weightlifting is more difficult because of their different body structure. However, strength training techniques (技术) are widely and successfully used by women, too.
Lots of the athletes who’ve ended up in Olympic weightlifting competitions have started with strength training only to improve their muscle condition and their body power. However, the demarcation line (界线) is not still very clear between power training and Olympic weightlifting. This is how so many lifters have got into Olympic weightlifting competition, even if their purpose was different at the beginning.

【推荐1】Twin sisters Wang Liuyi and Wang Qianyi won the women’s double free title to take China’s third gold in artistic swimming at the 19th FINA World Championships on Thursday.
The 25-year-old twins, who also won the women’s technical double and the women’s team technical, beat the Ukrainian and Austrian teams with a score of 95.5667 points. The Ukrainian Aleksiiva sisters, Maryna and Vladyslava, got the silver medal with 94.1667, while Anna-Maria and Eirini Alexandria of Austria came third on 92.8000.
“I feel very happy and excited to win the third gold medal for the Chinese artistic swimming team,” older sister Wang Liuyi told Xinhua. “The help of the coach and the encouragement of teammates have given us a lot of motivation. We have overcome tiredness and various difficulties. I did very well today and I’m satisfied with my performance.”
Wang Qianyi said: “This is the first time for us to compete in both the double and the team events, so I felt a little bit of pressure.”“In spite of tiredness, we were able to withstand (承受) this pressure. I feel very happy,” she added.
Since the start of the FINA Worlds, the sisters have delivered seven performances in the preliminaries and the finals.
According to Qianyi, a key to success was the winter training plan by the coach, which has laid a very good foundation for them. “In terms of physical fitness, both of us have greatly improved. The coach gave us a solid training and gave us a lot of trust. We are encouraging each other too,” she said.
On Friday, the sisters will compete in the team free final, which is their last event in the Championships. Wang Liuyi said: “We hope to be able to work together with our teammates in the final tomorrow, to have a better performance and achieve better results.” “The World Championships is a big test for us.

【推荐2】Lacrosse is an outdoor team sport of Native American origin. It’s played with rackets (球拍) called lacrosse sticks, crosses for short, and a rubber ball. The crosses are long sticks with triangular (三角形的) nets on one end used to catch, carry and throw the ball. The crosses are different lengths depending on the position of the team member. There’re short crosses that are about a meter long, and there’re long crosses that are 1.3 to 1.8 meters long. Lacrosse is played on a field that is 100 meters long and 55 meters wide. In addition, there’re goals at either end that are 1.8 meters by 1.8 meters with nets. All players wear helmets.
Teams consist of ten players each: a goalie, three defensive players, three midfielders and three attackmen. The object of the game is to get the ball into the opponents’ (对手的) goal with the crosses. The team with the most goals at the end of the game wins. The goalie guards the goal, and the defensive players stay near the goalie to help protect the area. The midfielders can go anywhere on the field. The attackmen are usually the players who score the goals.
The game starts with a face-off between two players at the center of the field to see which team gets the ball first. Players then use their crosses to pass the ball to team members, trying to get the ball into the opponents’ goal. The opposing team can take the ball by using the end of their crosses to try and knock the ball out of the net of another player’s crosse. Only the goalies can touch the ball with their hands. Players can use their bodies to bump (碰撞) other players to try to get the ball. This is called body checking, and it’s only allowed above the waist (腰) and below the shoulders.
Men and women play lacrosse, but the rules are slightly different for men’s and women’s teams. For example, the women wear less protective clothes and body checking is not allowed. Rules also differ depending on if the team is a youth team, a college team or a professional team.

【推荐3】It's not often to see a woman who’s seven months pregnant running a marathon. But Beatie Deutsch is anything but typical.
The 30-year-old mother of five is ranked as one of the top women marathon runners in the world and, as of today, has qualified for the 32nd Summer Olympics. What impresses people more deeply is that, unlike many Olympic hopefuls who have been training their whole lives, Deutsch only took up running four years ago.
Why did she train for a marathon? "I was really out of shape after having five kids," she said. "So I set the goal for myself of running a marathon and that helped me. I needed something to be motivated to get out there and train every day. I didn't ever expect it to take me to this."
The Israeli press has been tracking her with pride, calling her "Speedy Beatie". Hoping to add more purpose to her newfound fame, Deutsch uses her running as a way to raise money for a charity Beit Daniella. This nonprofit organization provides a recovery center for youths who are struggling with mental health issues.
That mission(使命)is helping fuel her Olympic dreams. At the Tiberias Marathon last month, Deutsch was the fastest woman in the race. This past September, she finished the Cape Town Marathon in two hours and thirty-six minutes. That's a few minutes shy of her personal best of two hours and twenty-nine minutes, a time that qualifies her for the Olympics. She will try to shave even more time off when she competes in the Rotterdam Marathon this April.
It's remarkable for someone who started her athletic career in her late 20s. "I always tell people to have big dreams, and set huge goals. Don't get caught up in the place where we are right now and have tunnel vision and are limited in what we see of ourselves," said Deutsch, who now travels the world as a motivational speaker.
1. What is the main reason for Deutsch's being impressive?A.Her typical birth place. | B.Her five lovely children. |
C.Her identity as a marathon runner | D.Her short time involved in running |
A.Creative. | B.Caring. |
C.Modest. | D.Adaptable. |
A.Deutsch’s dream | B.Deutsch’s mission |
C.Deutsch's achievement. | D.Deutsch's shy personality. |

【推荐1】Small talk has a reputation for being uninteresting, and for good reason. Pointing out the fact that it’s raining seems as ridiculous as pointing out the fact that you have a head—you’re fully aware of both things, and don’t require an outsider to confirm them. But despite being evident and often painfully dull, small talk has an important role to play, enabling us to overcome social obstacles towards improved , meaningful interaction (互动).
Humans can be sensitive souls. We each have our boundaries and lists of potential upsets, which when broken, cause us to either gently back away to an alternative position in the room, or become cross at the person. Small talk is first a way to test the waters with an unfamiliar person, so that you may better understand their character. When finding yourself positioned closely to a person who you know little about, it’s much safer to point out the rainy sky than to share your political views on a sensitive topic. Until you know the person better, heavier topics should probably be kept under wraps, so you won’t find yourself on the receiving end of a cold stare.
Though insignificant, small talk still has great power. When talking with fellow humans, much of our soul is exposed through non-verbal communication. A response to “how was your weekend” can unveil much about the person’s character. The length of their response might indicate their level of self-confidence; the tone of speaking might show how agreeable a person is; their slightly lowered head, as if protecting themselves from attack, a possible sign of a regrettable history of bullying.
As more of a person’s character is revealed, we have the insight needed to determine whether to broach more significant topics—the things that we actually want to talk about. Conversation is a great educator, and deep conversations establish lasting bonds with others, forming precious friendships that paint our lives with vibrant colors. Such friendships begin with small talk.

【推荐2】Efforts to preserve the Amazon rainforest, which supports immense biodiversity and locks away tons of climate threatening carbon, are growing more urgent as the ecosystem’s destruction speeds up. Indigenous (当地的) peoples have been trying to protect the region by patrolling (巡逻) their territorial boundaries for illegal activities. But rapid deforestation continues.
A recent study shows that combining on-the-ground monitoring with satellite data and smartphone technology could help put the brakes (刹车) on Amazon deforestation —and potentially that of forests elsewhere.
Illegal logging, agriculture and coca cultivation particularly threaten the Amazon in the Peruvian Indigenous communities and outsiders are often the culprits (罪魁祸首). The research team wondered if providing training for local people to use satellite based “early deforestation alerts (警报)” could help. The scientists cooperated with 76 Indigenous communities, 36 of which participated in using these alerts to watch over the forest. Over the next two years these trained participants were paid to work as forest monitors and received monthly alerts via the app when satellite data indicated local forest losses. Monitors investigated alerts, patrolled for deforestation in other areas and reported confirmed tosses back to their communities, which decided whether to deal with the culprits on their own or inform state authorities.
The researchers analyzed the same forest-loss satellite data from the given time period in all 76 communities. They found the early-alert program reduced forest loss by 8.4 hectares in the first two year — a 52% reduction compared with the average loss in the control communities.
Experts say this approach to tackling Amazonian deforestation looks promising. “Would this work in all communities that have high risk of deforestation? Given the results, it’s worth a try,” says Catherine Tucker, a researcher at the University of Florida. “But some communities may not have access to the resources needed for such a program, or their territories may hold valuable minerals that would increase the risk of deforestation by outsiders despite monitoring efforts,” wrote Francisco Hernandez Cayctano, a community member involved in the research, “we as Indigenous peoples ask the world for support.”

【推荐3】Fifty-five public schools in New York City have recently invited furry friends to their classrooms. The Comfort Dog Program has been around for five years.
Comfort dogs have been found to augment levels of oxytocin, serotonin and dopamine in our brains, hormones (激素) promoting positive feelings and a happy mood (心情). But how are these pets helpful in the classroom?
For some students the comfort pet provides the emotional support they need, which then allows the child to be engaged and successful in their studies. A struggling student can hold the pet in the arms and get the support he or she needs at the time, which also develops their self-awareness and ability to regulate their emotions. In other cases, teachers use the pet as part of the lesson. Meredith Loftus, a teacher in New York, brought a dog named Chip to help out with a phonies game in the classroom.
Dog training isn’t necessarily a walk in the park, although it can definitely include that. It takes time, effort and consistency to train pets, and this is the case for this program, too.
To be a part of the program, an educator and their dog must participate in a six-hour training session by The Good Dog Foundation. This training teaches the educator what to do if students are scared of pets. It also trains dogs on the differences they’ll experience in a school environment, such as the school bell, fire alarms, loud announcements and other possible distractions. The dog is also trained at being friendly with strangers and the handler, in this case the educator, who needs to be very in tune with the pet and know how to look out for its stress signals.
The program has been a genuine success so far, and a helpful addition to the education and well-being of many students in New York. In fact, hundreds of other schools have expressed their interest in joining the program and may be including it in their curriculum in the near future.

President Clinton arrived in Korea directly after leaving Japan and had not changed his culture gears.His failure to follow Korean customs gave the impression that Korea was not as important to him as Japan.
In addition to Koreans,some Asian husbands and wives do not share the same family names.This practice often puzzles(使困惑) English-speaking teachers when talking with a pupil’s parents.They become puzzled about the student’s correct last name.Placing the family name first is common among a number of Asian cultures.
Mexican naming customs are different as well.When a woman marries,she keeps her family name and adds her husband’s name after the word de(of).This affects(影响) how they fill in forms in the United States.When requested to fill in a middle name,they generally write the father’s family name.But Mexicans are addressed by the family name of the mother.This often causes puzzlement.
Here are a few ways to deal with such difficult situations:don’t always think that a married woman uses her husband’s last name.Remember that in many Asian cultures,the order of first and last names is reversed(颠倒).Ask which name a person would prefer to use.If the name is difficult to pronounce,admit it,and ask the person to help you say it correctly.

【推荐2】Teenagers have their own TV channels, websites and magazines. So what about books?
Last year one publisher, Martins, started publishing a series called Waves. We spoke to the director Julia Smith. She explained, "Teenage fiction has been published since the 1970s but publishers have never been very successful in getting teenagers to buy and read books. Now they're realizing that teenagers are just older children, but are not adults either. They are often not interested in adult fiction. For this series we are looking for new writers who write especially for teenagers.
Athene Gorr's novel was published in the series last year and is selling well. Its title is The Purple Ring. She says, "The important thing is to encourage teenagers to pick up your book. I'm a new writer. Although I've got an unusual name which people might remember, nobody knows it yet! But my book has a fantastic cover which makes people want to look inside. Then they realize what an excellent story it is!"
And what do teenagers themselves think about the series? We talked to Sophie Clarke, aged 15. She said? "I've read a few books in the Waves series. They say they are for 14-19 year olds and I agree with that. We're not interested in the same things as people in their twenties and thirties. I like them and I think they look really good too. The only thing is that because bookshops put them in the children section, lots of teenagers won't find them so they may not do very well. And it's a shame there's no such series as I think lots of teenagers, especially boys, might buy."

【推荐3】When we are born, we are unflawed. As we grow, we develop many complexities due to many influences in our lives. Our brain collects and retains all visual, auditory(听觉的)information from the moment we are born and to the smallest of the details. Apart from our brain having memory, cells in our body, in billions, have their own memory. In other words, our body stores both physiological and psychological memories. We are complex emotional beings in nature compared to any other living animal.
Apparently, physical and psychological memories strongly influence our emotions! Interestingly, we can create, store, and release emotion like energy. Moreover, if we do not process our negative emotions properly and suppressed for a long time, they can find a way out violently and unexpectedly. Unfortunately, we carry our guilt throughout our lives putting ever-increasing burden on our shoulders. We become heavy with guilt and anger for things we could or did not achieve, and for things we cannot have.
Both guilt and anger are useless for us. They give us no advantage. Therefore, one may ask: is there a way to put down the burden from our heavy shoulders? It is possible, indeed. Importantly, since our guilt and anger inside us neither released nor given attention, they are stored. Actually, we should process and address our emotions in order to remove from our system. We cannot just wish them away.
In fact, by acknowledging their presence and providing a channel for them to dissipate, we can dissolve our emotions gradually. Taking drugs and consuming alcohol only worsen situation. They only provide short-term comfort. Is there a better way to unload our burden? Luckily, we have a natural gift to process our feeling and emotions. Forgiveness stands first of all the other natural remedies.
Indeed, there is no better way than forgiving ourselves. Of course, we should also learn to readily forgive others. But when we learn to forgive ourselves, we also naturally forgive others.
In summary, there is no benefit carrying our years of emotional baggage. By forgiving, we can throw away the emotional baggage we carry for years. Forgive your past mistakes. The moment you start forgiving, you feel a lot lighter and years of heaviness lifted magically! To your surprise, you start feeling a lot energetic and optimistic in your daily life.

【推荐1】“Confidence” is probably one of the most noticeable quality in the Americans. They show confidence in the way they talk, the way they smile, the way they dress and the way they walk. Living and competing with all these confident American students, I find it extremely important to be confident as an international student and teacher. As a student, being confident means you should dare to raise your hand whenever a question or a point comes to your mind. Don’t mind if it sounds simple or silly. Otherwise you will never get a chance to speak in class at all. What’s worse, the professors may think you are not prepared for the discussion or you do not have your own opinion on the topic---this is the last comment any graduate would not like to receive.
Being confidence for me as a foreign teacher means calmly asking the student to repeat what he or she has said if I did not get it. Pretending to understand what you actually did not may just bring yourself uneasiness or even shame. But the time I most need to be confident is when my students come to my office and bargain about the grades I have given for their Speeches. (The course I’m teaching here is Public Speaking.) Modesty(谦虚) is a quality highly valued in China, but it won’t be of much help here if you want to survive and succeed in a good American graduate program.

【推荐2】April showers bring May flowers, as the saying goes. And with those flowers comes May Day, a holiday that most people have heard of but have no idea what it's for.
May Day, celebrated on May I every year, has its roots in ancient festivals marking the beginning of summer. Ancient Celts called it Beltane, which is still celebrated today. Over the centuries, it gradually developed in Europe, with maypole dances now connected with the holiday.
But May Day isn't all about skipping around with ribbons in the sunshine. It has also been on the same day as International Workers' Day since the 1880s. In fact, May Day is equal to America's Labor Day for certain countries.
On May 1,1886, hundreds of thousands of U.S. industrial workers took part in a nationwide strike to demand an 8-hour workday. (At the time. it was common to work 10 to 16 hours a day, according to Industrial Workers of the World.) The activities in Chicago lasted for several days, and on May 3. a strike at McCormick Reaper Works ended in a brawl with police officers. Several strikers were wounded or killed.
The next night, the violence became even worse. When police came to break up a crowd of people gathered in Haymarket Square, a bomb went off in the policemen. The bomb killed seven of them and wounded 60 more. Police then opened fire on the crowd, killing several men and wounding 200.
In honor of these events, now known as the Haymarket Affair, the International Socialist Conference declared May I as an international holiday for labor. That's why the world sees not only celebrations of warmer weather on the first day of May, but often marches for labor unions as well.

【推荐3】A Chinese company says it has created a new facial recognition system that can identify people even if they are wearing masks.
Engineers at the Beijing-based Hanwang Technology Ltd. say their system is the first to be created to effectively identify people wearing face masks. A team of 20 people built the system in about a month. The system is based on existing technologies developed over the past 10 years. The process involved adding a collection of about 6 million unmasked faces and a much smaller collection of masked faces.
Hanwang is now selling two main kinds of products that use the new technology. One performs “single channel” recognition, which is designed to be used at the entrances to buildings. The other product is a “multi-channel” recognition system that uses groups of surveillance cameras (监控摄像头).
“When wearing a mask, the recognition rate can reach about 95 percent, which can ensure that most people can be identified,” said Huang Lei, Hanwang’s vice president. He added that the system’s success rate for people not wearing a mask is about 99.5 percent.
Huang said Hanwang’s technology can be used to identify and track people as they move about. He added the system can identify crime suspects, terrorists or make reports or warnings.
However, the new system struggles to identify people wearing both a mask and sunglasses. “In this situation, all of the key facial information is lost. In such cases recognition is tough,” Huang said.
It was not immediately clear how people were reacting to the new technology. While some have expressed opposition to such tools, many others seem to have showed interest in the new system and accepted it as a way to deal with the current health emergency — the spread of the novel coronavirus (新型冠状病毒). Huang says he sees the interest likely expanding if the virus continues to spread and the use of face masks increases.
