Tai chi, a traditional, slow-moving form of Chinese physical exercise, is known to increase flexibility and improve balance. New research has been conducted to determine whether tai chi has an influence on lowering blood pressure in people with prehypertension (高血压前期).

In the study, Chinese scientists put 342 adults with prehypertension into two groups. The average age of people taking part in the study was 49. About half the participants (参与者) took part in aerobic exercise, including jogging, climbing stairs and cycling. The other half was trained to practice tai chi. Both groups got hour-long exercises four times a week.

Nearly 22% of the people who practiced tai chi saw their blood pressure fall to be normal, compared with nearly 16% of people in the aerobic exercise group. And fewer patients in the tai chi group went on to develop high blood pressure than patients in the aerobic exercise group.

So what is it about tai chi that helps lower blood pressure? “The practice tends to get more of a response from the parasympathetic (副交感的) nervous system, which is the network of nerves that relaxes your body after periods of stress or danger,” says Ruth Taylor-Piliae, a professor at the University of Arizona’s College of Nursing.

“I think the beauty of tai chi is that you don’t have to have a special gym membership, you don’t have to have special clothing,” Taylor-Piliae says. “Once you learn tai chi, you can do it anytime and anyplace. And it does provide a calming and relaxing effect.”

Evidence suggests it can also help protect against cognitive fall and even improve memory. But you have to practice it continually to get the most benefit.

1. What is the function of paragraph 1?
A.To offer some examples.B.To explain a definition.
C.To introduce the topic.D.To give people suggestions.
2. What can we know about the participants in the study?
A.They were divided into two groups.B.They suffered from heart disease.
C.They were 49 years old.D.They got exercises five times a week.
3. What might Taylor-Piliae agree with about tai chi?
A.It can make people calm down.
B.It requires training and specialized equipment.
C.It has no influence on the parasympathetic nervous system.
D.It is suitable for individuals with aerobic exercise experience.
4. Which is the most suitable title for the text?

文章大意:这是一篇新闻报道。文章介绍了76岁的埃迪是英国年龄最大的女子铁人三项运动员,并且参加了多次马拉松比赛,除此之外她还在2013年发起了慈善机构Silverfit,为老年人推广体育运动的事迹。

【推荐1】It’s no wonder they call her Iron Gran. At the age of 76, she’s the UK’s oldest female Ironman triathlete (铁人三项运动员), and has lost count of the number of marathons she has run. Just as incredible is the fact that Edwina Brocklesby or “Eddie” as she’s known only took up running in her 50s. With her boundless energy and infectious smile she inspires everyone she meets.

As well as her personal achievements, the super-granny also launched the charity Silverfit in 2013. It promotes sport for older people and started with events in London’s parks and has since grown to have 2,000 members. Silverfit offers a range of activities to the over-45s. To make sure no one is excluded due to cost, membership is only £12 per year. As Eddie says: “It’s absolutely essential with our aging population that—they age healthily and that they have fun doing so. Our core message is that it’s never too late to start exercising.”

Len Bass, 76, has been coming along for two years. He wanted to get fit after surviving stomach cancer that left him barely able to walk. Within weeks of joining he had begun to see a difference. “I was bent over when I started, but by the end of the first month I could run up hills. Thanks to Silverfit, today I am really fit, I am off all medication.”

And Marjorie Barnes, 62, from Dulwich added: “I had terrible back problems, and was walking with a stick when a friend recommended Silverfit. I joined Silverfit and within a year I’d alleviated (减轻) my back problems and even entered the London half marathon. I’ve got my freedom back and it’s all down to the wonderful Eddie. She’s amazing.”

Eddie’s personal drive to get fit was driven by her husband’s sudden death in his 50s. Now Eddie has completed at least 12 marathons. “Running with friends helped me dramatically after I lost my husband. My advice would be to make the best of your life, and have fun.”

1. What can we learn about Eddie?
A.She came to running late.
B.She is the oldest marathon runner.
C.She broke the record for a marathon.
D.She always goes on trips to scenic spots.
2. Why did Eddie start a charity?
A.To kill her leisure time.
B.To raise money for her career.
C.To support Ironman triathletes.
D.To encourage the old to exercise.
3. What did Len Bass say about Silverfit?
A.It helped him realize his marathon dream.
B.It freed him from his medication.
C.It helped him make a friend.
D.It became a burden to him.
4. How might people most probably find Eddie’s story?
A.Uninteresting.B.Unbearable.C.Inspiring.D.Complex.

【推荐2】More than 30,000 people went to the White House on Monday for the 136th Easter Egg Roll (复活节滚彩蛋). President Barack Obama and First Lady Michelle Obama held the event by inviting thousands of kids to color and look for eggs. The theme(主题) of the day was “Hop Into Healthy, Swing Into Shape.” It was part of the First Lady’s “Let’s Move!” program to reduce obesity rates (肥胖率) among American kids. Mrs. Obama spoke to young reporters about her goal(目标) to get children to eat right and keep moving.

“We are working to make sure that kids born today grow up healthy, learn how to have balanced meals, and get more physical activity into their lives,” she said.

Mrs. Obama said she wants children across the nation to understand that "exercise isn't just hard work, it's play. If you’re running around with your dog, you're getting exercise. If you walk up the stairs, that's exercise, But if you’re sitting in front of the TV or on a computer game, you're not exercising.”

The First Lady said that for kids who have balanced meals most of the time, having a special snack, like chocolate, will not hurt." And if you are active, you can splurge (挥霍) a little more," she said. Mrs. Obama’s favorite "splurge food" is French fries. But she balances her splurging by exercising almost every day. She loves to play tennis and she practices yoga.

“A lot of kids look up to(敬仰) athletes, and I think it's important for athletes to share their good habits,” Mrs. Obama said. "Kids aren’t just going to wake up and be LeBron James. He's practicing and eating right and working out and training. Our athletes can be really good messengers to kids who look up to them--they can say to kids, 'If you really want to be like me, then you really do need to eat your vegetables.’”

【推荐3】Soccer legend: They told me girls couldn't play this game

Note: Michelle Akers was a player on the US Women's National Teams who won World Cup titles in 1991 (where she won the Golden Hoot as top scorer) and 1999.

(CNN) — In third grade, I shared my dream along with my favorite football with the class, and as I proudly finished my speech, my teacher responded, "Michelle, girls cannot play football" to which I answered, "Yes, I can." I wouldn’t let it go, landing myself in the principal's office, trying not to cry. Soon, my mom arrived. “God help me now,” I thought ... until I heard her say to both my teacher and the principal, “How dare you tell my daughter what she can or cannot do.”

On Wednesday, all the world (myself included) will watch the 2019 US Women's National Team — Women's World Cup champions. I'm also thinking about how they — like I — got to the place where they lifted that trophy. To me, the 2019 World Cup and above all, this team, has taken the stories and dreams of the USWNT full circle.

It goes like this: First, you dream. Next, you play. Then, you inspire a legacy.

So many years ago, I dreamed of being a Pittsburgh Steeler. But many of the players on this 2019 World Champion USA Team sat in stadiums or watched games on TV in 1999 and dreamed of playing for the USWNT. No one could tell them they couldn't — they could see for themselves that it was possible.

They have now not only won a World Cup, but have turned their dreams into action. Dreams of being the best in the world. Dreams of equality and equal opportunity. And the actions to back them up and make them real for the people who come after them. They are demanding respect and equality from the powers that be because they know what it is to achieve more than just a trophy.

That, for me, is so very powerful. What this 2019 World Champion team demands for themselves — and put first in their lives — will be their biggest message of change: Respect. Equal opportunity. Team and family. Individual choice. Excellence. Into a new era.

And I am grateful to be celebrating them in their much deserved ticker-tape parade in the Canyon of Heroes in NYC.

1. What's the attitude of Michelle's mom towards her dream?
A.Funny.B.Supportive.C.Ambiguous.D.Carefree.
2. What can we infer from Paragraph 2 about the 2019 Women’s World Cup?

A.She set an example to women football players.
B.She won the Golden Boot in 1999.
C.She retired from her team in 2019.
D.She recognized inequality to women in football.
4. Which of the following can be a suitable title lor the text?
A.Dream, Play and InspireB.Woman Football Develops
C.Football Counts More than EverD.Equal Playing Field Is More than Men's
