1 . The benefits of regular exercise are well documented but there’s a new bonus to add to the ever-growing list. New researchers found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia in later life, and as they did, it came on a decade later than less sporty women.
Lead researcher Dr. Helena Horder, of the University of Gothenburg in Sweden, said : "These findings are exciting because it’s possible that improving people's cardiovascular （心血管的）fitness in middle age could delay or even prevent them from developing dementia. "
For the study, 191 women with an average age of 50 took a bicycle exercise test until they were exhausted to measure their peak （最大值的） cardiovascular capacity. The average peak workload was measured at 103 watts.
A total of 40 women met the criteria for a high fitness level, or 120 watts or higher. A total of 92 women were in the medium fitness category; and 59 women were in the low fitness category, defined as a peak workload of 80 watts or less, or having their exercise tests stopped because of high blood pressure, chest pain or other cardiovascular problems.
These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.
"However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association. More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important. " She also admitted that a relatively small number of women were studied, all of whom were form Sweden, so the results might not be applicable to other groups.

2 . The Biggest Stadiums in the World
People have been pouring into stadiums since the days of ancient Greece. In around 80 A.D., the Romans built the Colosseum, which remains the world’s best known stadium and continues to inform contemporary design. Rome’s Colosseum was 157 feet tall and had 80 entrances, seating 50,000 people. However, that was small fry compared with the city’s Circus Maximus, which accommodated around 250,000 people.
These days, safety regulations-not to mention the modern sports fan’s desire for a good view and comfortable seat — tend to keep stadium capacities (容量) slightly lower. Even soccer fans tend to have a seat each; gone are the days of thousands standing to watch the match.
For the biggest stadiums in the world, we have used data supplied by the World Atlas list so far, which ranks them by their stated permanent capacity, as well as updated information from official stadium websites.
All these stadiums are still functional, still open and still hosting the biggest events in world sport.
·Rungrado 1st of May Stadium, Pyongyang D.P.R. Korea. Capacity: 150,000. Opened: May 1,1989.
·Michigan Stadium, Ann Arbor, Michigan, U. S. Capacity: 107,601. Opened: October 1, 1927.
·Beaver Stadium, State College, Pennsylvania, U. S. Capacity: 106,572. Opened: September 17, 1960.
·Ohio Stadium, Columbus, Ohio, U. S. Capacity: 104,944. Opened: October 7,1922.
·Kyle Field, College Station, Texas, U. S. Capacity: 102,512. Opened: September 24, 1927.

3 . One of the best parts of the school day is the time spent in the playground. It’s a chance to be with friends, run around and have fun. However, at the Rudyard Kipling Primary School in Brighton, things were getting too hard, so the teachers decided something had to be done. The school’s new rules, which restrict（限制）physical activities and encourage pupils only to touch if they are playing friendlier games, have attracted a lot of attention.
Most people say that they are a bad restriction. Parents of children at the school, in Brighton, East Sussex, talked about the bizarre rule — saying their kids were now bored at playtime. A teacher for the school defended（辩护）the rules, saying, “We want to make sure the playground is a happy, safe and calm place where everyone can enjoy their lunchtime running around and getting the exercise that we know is important to them.”
Some people say that Rudyard Kipling Primary School’s decision is a good one because it makes the playground more fun for everyone. Not all children enjoy playing rough（剧烈的）games or sports at playtime. Friendlier games ensure everyone can join in. The teachers only have the pupils’ best interests at heart, so they should be trusted to make the right decision. Besides, if someone gets hurt in the playground, that could distract（分心）the teachers from other accidents.
However, some people think it’s an overreaction. Sometimes physical games can lead to injuries, but banning（禁止）such activities is unreasonable. In fact, it is only during physical games that you can build up your ability to recover quickly from falling over. Even if these physical activities aren’t your favorite way to spend break time, it’s difficult to see why they will be completely banned. Each pupil should be able to decide what they want to do. Besides, schools should be happy that their students want to exercise between classes as this will keep them fit and healthy, and teachers should encourage this, not prevent it.

6 . When it comes to making healthy lifestyle changes, which should come first-changing your diet or becoming more physically active?
Previous studies suggested that providing people with too much information about nutrition and physical activity at once tends (趋向) to be discouraging. That has led to the popularity of advising people to make changes gradually, and set smaller goals.
So the scientists divided 200 inactive participants who were 45 or older into four groups. One group was instructed in making diet and fitness changes at the same time; the second group was taught about diet changes first, and then fitness changes four months later; the third group changed their exercise habits first and made changes in their eating habits four months later; and the final, control group was not instructed in either diet or fitness changes but in how to manage their stress.
The researchers followed the groups for a full year. Compared to the control group, the three intervention (干预) groups made healthy changes in their diet. Those who changed their fitness habits first significantly increased the amount of exercise they received daily compared to the other groups after four months. However, at the end of the year, the group that changed both diet and exercise at the same time was the only one that met the nationally recommended targets for both exercise and nutrition levels, while those who worked on improving their nutrition first were unable to meet the recommended levels of fitness after a year. The researchers suspect that changes to diet are easier to make than changes to physical activity.
The findings show, however, that pairing diet and exercise changes may help to overcome some of the barriers people face in adding more physical activity into their lives. If folks change diet and exercise orderly, the scientists say, they may end up placing more importance on the first set of behavior changes and feel less pressured to address the second set.

7 . Brazil is the greatest football nation in the world. There are 170 million Brazilians. How many of them are football fans? 100 million! All of them think that they know all about football. This makes life very difficult for the Brazilian team managers. When things go bad for the Brazilian team, the newspapers would demand that the team manager should leave his job. “If we win, they put me in heaven,” a manager once said. “If we lose, they put me in hell (地狱).”
You can’t escape football in Brazil. There are football matches on every street and beach. On television, the results of football matches come before the main news programs. There are six television channels (频道) in Rio de Janeiro. On Sundays each channel shows a different football match.
Brazil is not the richest country in the world, but the government spends lots of money on football. It cost more than one billion pounds to prepare for the 1978 World Cup. That’s 10 pounds for every Brazilian man, woman, and child. And many Brazilians don’t earn as much as 10 pounds a week. Is it worth it?
“Brazil must have a great football team,” says one journalist. “If it costs one billion pounds, that’s all right. If the government doesn’t give us a good team, then it will become unpopular. Football is more than a game in Brazil.”
Football is more than a game in Brazil. This is certainly true in its largest city, San Paulo. The most popular team is Corinthians. Corinthians’ fans are the most loyal and emotional in Brazil. When Corinthians win, production in the Sao Paulo car factories increases by fifteen per cent. When they lose, it drops. At one time Corinthians won the national championship for the first time. For four days fans danced and sang in the streets.
Why are people so loyal to one football team? What makes a football fan? One man says, “Without Corinthians my life would be sad. Corinthians bring some joy and excitement into my life. We all need that, don’t we?”

8 . For some people, walking or running outdoors is a great way to work out. What may not be so pleasant is seeing trash all over the ground. Well, some people are doing something about it. They are logging!
“Plogging” began in Sweden. The name combines the Swedish word “plocka” which means to pick up, and the word “Jogging”, which means to run slowly. A Swedish man named Erik, started the movement in 2016. On the World Environment Day website, Erik says that he moved to Stockholm from a small community in northern Sweden. Each day he would ride his bike to work.
Concerned about the amount of trash and litter he saw each day on his way to work, he took matters into his own hands.
Flogging, by that term, may have officially begun in Sweden. But many people who exercise outdoors have been doing this for years. Take Jeff Horowitz, for example. He is a personal trainer in Washington D.C. He often picks up trash while running outside. He even has turned it into a game. He will try to pick up the trash without stopping. “I didn’t know it was a thing really. This is just my personal ethics (道德标准) where I go for a run and if I happen to see a piece of garbage lying around and it’s within reach — it is a kind of a little test for me to see if I can grab it and throw it in a near trash can without stopping. And that way, I think, it gives me a little exercise and a little focus for my run. And it helps clean up the neighborhood,” he announced.
Today, logging is an official activity, one that is becoming increasingly popular. Cities around the world now hold plogging events. “I would just hope people would think twice before dropping a garbage on the ground. We have containers…seems on every block. So, it’s easy to put your garbage in the trash cans. I just think people should think about it a little bit more. I do hope one day there will not be a need for logging.” said an interviewee.

| B．New Exercise Enjoys unbelievable popularity |
| C．Plogging — a Fashionable Way to clear waste |

9 . Runners need to move 15 per cent faster on a treadmill(跑步机) to burn the same number of calories as jogging outdoors, research reveals.
Researchers from Milan University analyzed the difference between running outdoors and on a treadmill in 15 physically fit males with an average age of 21. The participants completed a sprint(短距离快速跑) for 30 seconds followed by 30 seconds of recovery for a total of 15 minutes both outdoors and on a treadmill. Oxygen use and exercise intensity were measured after both types of running.
The findings were published in the journal of Applied Physiology, Nutrition and Metabolism. Results revealed that when on a treadmill, runners use significantly lower amounts of oxygen, suggesting less effort is required. Therefore runners must move 15 percent faster on a treadmill to burn the same amount of calories as exercising outdoors, the study stated. The study authors wrote, "A 15 per cent increase in running speed during a period of stopping and starting often in high intensity treadmill training session is the best possible solution to reaching the same physiological responses as an outdoor training session.
Although the study did not speculate why treadmill running appears to be needing less effort and energy, previous research suggests the moving belt of a treadmill moves joggers forward, causing them to move faster. Exercising indoors also means gym-goers do not have to fight with steep hills or wind resistance.
Michael Silverman, director of rehabilitation and wellness(康复科) at Northern Westchester Hospital in New York, said, “Outdoors, you are changing surfaces constantly, fighting the wind, and making quick and sudden starts and stops, which will lead to increased caloric burn.” Shake magazine reported. "And while we don't recommend running in extreme temperatures, it is worth noting that your body burns extra calories to regulate your body temperature," he says.

10 . Exercise helps to keep us in good health. Doctors at the American Heart Association suggest getting at least 150 minutes of moderate physical activity every week. Many people exercise for a few minutes every day or every other day. So, getting 150 minutes every week is easy.
But what about those times when you are sick? If you do not feel well, should you keep following your exercise habit? Following are the answers from health experts.
Edward R. Laskowski is a doctor at the Clinic. He and other experts have a general rule about exercising when you are sick. It is usually fine to exercise mildly, he explains, if your symptoms are all “above the neck”. These signs may include a runny nose, nasal congestion, sneezing or a minor sore throat.
Geralyn Coopersmith, a physical fitness trainer who has written several books on exercise and nutrition offers similar advice. However, both Coopersmith and Dr. Laskowski suggest taking a break from exercising if signs of your illness appear “below the neck.” Pay special attention to symptoms such as chest congestion, extreme cough or pain in the stomach.
There are other symptoms(症状) that can tell you to avoid exercise. They include: a higher than normal body temperature, a sense of feeling extremely tired, and widespread muscle pain.
Both Coopersmith and Dr. Laskowski suggest listening to your body. If you feel really bad, take a break and let your body rest. If you don’t feel too bad, these experts both suggest reducing the amount of exercise. For example, if you usually run, take a quick walk instead.
1. Which of the following statements is true?| A．It is a hard thing for people to exercise for 150 minutes every week. |
