A study has found that a lifetime of regular exercise and activity can slow down the aging process and a life of movement and exercise may help us live longer and healthier.
For their study, the researchers looked at two groups. The first group was made up of 125 non-professional cyclists between the ages of 55 and 79. This group included 84 healthy men and 41 healthy women. We will call this group the “cyclists”.
Researchers then found 130 people to make up a second group. Within this group, 75 people were aged from 57 to 80. The other 55 were between the ages of 20 to 36. The people in this group were also healthy, but they didn’t exercise regularly. We will call this group the "non-exercisers". Smokers, heavy drinkers of alcohol (酒) and people with other health problems were not included in the study.
Then, researchers gave both groups a series of tests. They tested their muscle mass (肌肉质量) , muscular strength, percentages of body fat and the strength of their immune systems (免疫系统). Then the researchers compared the results of the two groups.
Results showed that the cyclists didn’t experience body changes usually regarded as a normal aging process. For example, they didn’t lose muscle mass or muscular strength. Also, their body fat didn’t increase with age. The researchers also found something they had not expected. The study showed that the immune systems of the cyclists didn’t age either. The researchers advise us all to find an exercise that we like in our lives.

Warm up, cool down
Drink water
You might not feel hot, but that's because sweat evaporates (蒸发)more quickly into the chilly, dry air. So be sure to drink water before, during and after cold-weather workouts.
Running in cotton is a bad idea. Wear thin, breathable layers of synthetic (合成 的))clothing that help protect you from the wind and snow, but still let out heat and moisture (水分).Thirty percent of your body heat escapes through your hands and forty percent through your head. Wear a hat, or beanie (无边小便帽), and gloves so your circulatory system can distribute warm blood to the rest of your body.
Run into the wind
A.Dress right |
B.Keep warm. |
C.Don't go too fast, too soon |
D.Start and finish in the same way. |
E.Don't wait to drink water until you feel thirsty. |

Some sports or games go back thousands of years, like running or jumping. Chinese wushu, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time. Water-skiing is one of the newest in the family of sports.
People from different countries may not be able to understand each other, but after a game together they often become good friends. Sports help to train(培养,训练) a person’s character(性格,品格). One learns to fight hard but fight fair, to win without pride and to lose with grace(胜不骄,败不馁).

【推荐1】The newly-elected president of Brazil, Jair Bolsonaro says that his country should withdraw (退出) from the 2015 Paris Agreement, and that Brazil’s rainforest protections are standing in the way of economic success. During the election campaign, he promised to ease protections for areas of the Brazilian Amazon set aside for native people and wildlife. Are Brazil’s rainforests in danger?
The Amazon, the world’s largest rainforest, is called “the lungs of the planet.” Each tree takes in and stores carbon dioxide from the air around it. Billions of trees pull up water through their roots and release water vapor into the air, forming tiny drops of water. The Amazon creates 30 to 50 percent of its own rainfall. Carlos Nobre, a climate scientist, says that it is almost impossible to say Just how important the rainforest is to the planet’s living systems.
Some of Bolsonaro’s support comes from business and farming groups. One supporter, Luiz Carlos, noted that farmers “are not invaders, they are producers.” He blamed the past government for supporting rainforest protections at the cost of farmers. “Brazil,” he said, “will be the biggest farming nation on Earth during Bolsonaro’s years.”
Paulo Artaxo, a professor of environmental physics at the University of Sao Paulo, says that if Bolsonaro keeps his campaign promises, then “deforestation of the Amazon will probably increase quickly — and the effects will be felt everywhere on the planet.”
Other scientists warn that if the Amazon and other tropical rainforests lose too many trees, this could affect rainfall in other areas. Without enough trees to support the rainfall, the longer and bigger dry season could turn more than half of the rainforest into a tropical grassland.

【推荐2】In the past few decades, the way we shop has changed dramatically. We used to buy our goods in traditional shops. Now, customers are increasingly buying online, where they can order whatever they want directly to their door with the click of a mouse. As companies race to improve their Internet shopping experience, the trend towards shopping online is predicted to continue.
Most people commonly think that online shopping is better than in-store shopping. After all, an online store does not use the electricity that a traditional store might use and it doesn't require the customer to drive anywhere. So you would think the carbon savings must be significant.
Take the typical home delivery round in the UK, for example. Supermarket drivers often do 120 deliveries on an 80-kilometre round, producing 20 kilograms of CO2 in total. In contrast, a 21-kilometre drive to the store and back for one household would produce 24 times more CO2! However, the reality is slightly more complex than that. Many home deliveries fail the first time and the driver has to make a second or third attempt to deliver the purchase.
The carbon footprint also goes up if the customer chooses to return the item. A study in Germany shows that as many as one in three online purchases are returned. According to another study, merchandise(商品)worth nearly $326 million is returned each year in the USA. Two billion kilograms of this ends up in landfill(垃圾填埋池), leading to 133 tons of CO2 being released.
When we take all these factors into consideration, we realize that online shopping isn't necessarily as green as people might think. There is some positive news, as various online retailers(零售商)are starting to lower their carbon footprint by turning to electric delivery vehicles. However, the question of how to deal with returns efficiently and without waste is a challenge that many companies have not wanted to face, but they have to shoulder responsibilities.
1. What is a common belief about online shopping according to the text?A.It increases companies' pressure. |
B.It costs less than in-store shopping. |
C.It is more environmentally-friendly. |
D.It improves customers' shopping experience. |
A.online shopping is sometimes inconvenient |

C.customers should think twice before shopping |
D.online shopping may cause much carbon footprint |
A.By cutting the distance of delivery. | B.By using a greener way of delivery. |
C.By choosing to sell electric vehicles. | D.By recycling their customers' returns. |
A.Online shopping has bad impacts on the environment. |

【推荐3】It's been a year since the dramatic rescue of the 12 members of the junior football team and their Coach from the Tham Luang Nang Non cave in Chiang Rai Province, Thailand. The rescue put a spotlight on cave exploration and the adventures that people can have underground. Caves have an almost primal(原始的)appeal—they hold the secrets to our past and are mysterious in themselves. They are home to mini-ecosystems that could not exist above ground.
Mammoth Cave, Kentucky, USA
The longest cave system in the world lies beneath the Green River Valley in Kentucky, and while over 400 miles of passageways have been mapped, it has yet to be fully explored. The complex limestone labyrinth(石灰岩迷宫)was discovered by humans 4,000 years ago and is home to a rich habitat of many rare animals, including eyeless fish and cave salamanders(火蜥蜴).
Avshalom Cave Nature Reserve, Beit Shemesh, Israel
Also known as the Soreq Cave Nature Reserve, Avshalom is considered to be the Rosetta Stone(罗塞塔石碑)of climate history in the Eastern Mediterranean due to thickly packed stalactites(钟乳石)found in the cave, some of which are over 13 feet long and are as old as 300,000 years.
Crystal and Fantasy Caves, Hamilton Parish, Bermuda
A truly magical experience below the earth, these caves were formed in the Pleistocene Era(更新世), but only found by humans just over 100 years ago. Groups of crystals and stalactites hang above a crystal-clear pool that is a mix of fresh and salt water and is almost 60 feet deep.

【推荐1】Visitors to Henn-na, a restaurant outside Nagasaki, Japan, are greeted by a unique sight: their food being prepared by a row of humanoid robots. The "head chef", named Andrew, is using his two long arms:he stirs batter(面糊)in a metal bowl, then pours it onto a hot grill. In a nearby hotel, robots check guests into their rooms and help with their luggage.
CEO Hideo Sawada, who runs the restaurant and the hotel, predicts that 70 percent of the jobs at Japan's hotels will be automated in the next five years. He said, "Since you can work them 24 hours a day, and they don't need vacation, in the end it's more cost-efficient to use the robot."
This is seemingly worrying. In fact, in America, automation(自动化)helps the food-service and accommodation sector continue to grow. In the company Panera, because of its new kiosks, an app that allows online ordering, the chain is now processing more orders overall, which means it needs more total workers to meet consumers' demand. Starbucks customers who use the chain's app return more frequently than those who don't, the company has said, and the greater efficiency that online ordering allows has increased sales at busy stores (luring peak hours. Starbucks employed 8% more people in the U. S. in 2016 than it did in 2015, the year it began to use the app.
Of course, whether automation is a net benefit to workers in restaurants and hotels, and not just a competitive advantage for one chain over another will depend on whether an improved customer experience makes Americans more likely to dine out and stay at hotels, rather than brown-bagging(自备午餐)it or find an Airbnb to book unique homes.

【推荐2】Studying a subject that you feel pointless is never a fun or easy task.If you’re studying history, asking yourself the question “why is history important” is a very good first step. History is an essential part of human civilization. You will find something here that will arouse your interest, or get you thinking about the significance of history.
History grounds us in our roots. History is an important and interesting field of study, and learning the history of our home country can give us a deeper, more meaningful glimpse(一瞥)into our ancestral pasts, and how we got to where we are today. Many people feel like they need a sense of cultural belonging, which is something that studying your roots and being open-minded to the evolution of your culture can provide.
History enriches our experience. Reading history is an amazing experience because it enables us to reflect on the social and economic life of the people living long time ago. According to the experts, problems faced by people regardless of the past and present are the same.With the information about the ancestors, one can become more experienced in handling challenges of life.
History makes us more empathetic(具有共情能力的). Studying history can give us insight(洞察力)into why our culture does certain things, and how the past has shaped it into what we know now. It also provides a rather strong foundation for empathy across cultures. Fear and hate for others is usually caused by ignorance(无知).We’re scared of the things that we don't understand. History has the potential to break down those boundaries by offering us insight into entire worlds that would otherwise be foreign to us.
History can inspire us to learn more. What's fantastic about history is the way it broadens our horizons. It’s almost impossible to learn about one historical period without having dozens of questions about related concepts. Study the 19h century England, and you might catch a glimpse of Charles Dickens’ Oliver Twist. Look up Charles Dickens, and you might learn a thing or two about realism. Or maybe you end up switching your attention away from novels, and discover the history of romantic poets in England. It can go anywhere, and there is something in there for absolutely anybody.
The value of history cannot be underestimated. We don't have to live in the past, but we can definitely do better by learning from it and using the lessons learned to lead more meaningful lives.

【推荐3】School children across the United States have been taking part in local and state spelling competitions. These competitions are called spelling bees. The young competitors spell words that even some adults may never have heard of.
More than 280 local winners will earn the right to compete in this year’s Scripps National Spelling Bee. The event will take place from May 28 to June 3 near Washington, D.C., at the National Harbor in Maryland.
Most competitors in the National Spelling Bee are between the ages of 12 and 14. But this year, one competitor will be less than half that age — five-year-old Edith Fuller.
Last weekend, she won an area spelling bee in her home state of Oklahoma. The five-hour competition lasted 37 rounds. Edith correctly spelled words like sevruga(闪光鲟鱼子酱), jacamar (a kind of bird), and Nisei (a child of Japanese immigrants).
Her winning word? Jnana, a Sanskrit(梵语的) word that is related to having a higher level of knowledge. Remember, Edith is five. She is the youngest person ever to qualify for the National Spelling Bee.
Not so long ago, when she was just four, Edith surprised her parents when she was able to spell the word “restaurant”. At that moment, her mom and dad realized their child might have a mental gift.
Edith is home-schooled. So, her parents are able to spend a little more time teaching her to spell.
About two percent of US children are home-schooled. Yet, home-schooled kids usually make up 8 to 10 percent of those who make it to the National Spelling Bee.
Now, the Fullers must prepare young Edith for the national bee. But no matter how she does there, Edith is already being called a “spellebrity”.

【推荐1】Traditional Chinese medicine(TCM) is an ancient form of healthcare that dates back over 2,500 years, which aims to prevent or cure disease by maintaining or restoring yinyang balance. Fundamentally, TCM seeks to restore a dynamic balance between two complementary forces, yin(passive) and yang(active) . According to the yinyang theory, a person is healthy when harmony exists between these two forces; illness, on the other hand, results from a breakdown in the balance.
TCM practitioners(从业者) look to treat the root cause of disease and take a holistic approach to helping people experience complete recovery without the use of conventional drugs. TCM is “holistic” because it takes into account all aspects of a patient's life, rather than just several obvious symptoms. TCM practitioners view the body as a complex system, rather than separate organs. They use smell, hearing, touch, and pulse diagnosis(诊断) to discover the source of an unbalanced health condition. In addition, the practitioner typically makes use of what is known as five phases(wuxing) . Using the five-phase theory, the practitioner can create a plan for treatment that might contain such components as herbs, lifestyle changes, and foods for recovery.
Over the past several decades, TCM has been going global. It is now practiced in 183 countries and regions with 86 of them signing agreements with China to promote it. More and more medical schools are now recognizing the importance of training students and staff in “mind-body” practices that emphasize disease prevention and holistic treatments. A study of 3,200 physicians, conducted by Health Products Research, indicates that more than 50 percent of physicians in the U. S. planned to begin or increase use of TCM.

【推荐2】Six supporters of PETA (People for the Ethical Treatment of Animals), including one inside a cat costume and another dressed as a pig, marched on the sidewalk outside High School District 113 in Highland Park, Illinois, US. Their goal was to get the district to end animal dissection in science classes.
Animal dissection has always divided people: Is it right to dissect frogs, pigs or other animals in school science classes, particularly when computers can show detailed images of the parts of animals?
“Especially with all the violence in the US, it is important we teach children compassion for all living beings, said Mysti Lee, assistant campaign manager for PETA.
The American Anti-Vivisection Society reports that 18 states, including Illinois, have laws allowing students to choose alternatives to dissection. And in recent years, biology classes have moved toward the study of cells, molecules and genetics. “Dissection is horrific and unnecessary,” protester Victor Przysiezny said.
However, most biology teachers believe that dissection is an important part of education when done right. “It’s one thing to see it on a computer screen,” said Jaclyn Reeves. “Its another to see the size and scale. Science is about getting your hands dirty.” She added that dissection can inspire students to take up a career in biology or put them off.
At its recent protest in Highland Park, PET A singled out Bio Corp., a company that provides frogs, pigs, turtles, rabbits, cats and other animals and their parts for educational purposes. Following the charges of animal cruelty, Bill Wadd, co-owner of Bio Corp., invited city officials to tour Bio Corp. He said that more than 98 percent of the animals Bio Corp received last year were already dead. “We just take what people would throw away,” Wadd said. “Instead of throwing it in the trash, why not have students learn from it?”
District 113 spokeswoman Christine Gonzales said that district officials would think about using computer images in class instead. “We are always looking for new and innovative methods, because we do want to ensure our kids get the best instruction and are kind to all creatures,” she said.
