Dr Andrea Collins from Cardiff University told the BBC: "Training for a marathon makes you more sustainable in day-to-day activities.

6 . Hailing from Sweden, “plogging” is a fitness craze that sees participants pick up plastic litter while jogging adding a virtuous, environmentally driven element to the sport. Plogging appears to have started around 2016, but is now going global, due to increasing awareness and __ over plastic levels in the ocean.

The appeal of plogging is its __—all you need is running gear and a bin bag, and the feeling of getting fit while supporting a good cause. By adding regular squats(蹲) to pick up junk and carrying __ to jogging. we can assume the health benefits are increased.

Running and good causes have always gone __ — just think of all the fundraising marathon runners do. But there couldn’t be a more on-trend way of keeping fit than plogging.

Anything that’s getting people out in nature and connecting __ with their environment is a good thing, says Lizzie Carr, an environmentalist who helped set up Plastic Patrol, a nationwide campaign to __ our inland waterways of plastic pollution. There’s been a real __ in the public mindset around plastics, helped by things like Blue Planet highlighting how disastrous the crisis is,” she says.

We need to keep momentum high and the pressure up, and empower people through __ like plogging and Plastic Patrol.

The plastic Patrol app allows users to __ plastic anywhere in the world by collecting discarded items, photographing them and __ to the app, giving us a better knowledge of what sorts of plastic and which brands are being thrown out. “I’d urge all ploggers to get involved,” adds Carr.

Plogging isn’t the first fitness trend to combine running with a good cause, Here are some of our favourites:

Good Gym

Its idea is simple: go for a run, visit an elderly person, have a chat and some tea, and run back.

__ among the elderly is a growing problem in the UK. With over 10,000 runs so far, __, Good Gym is finding a solution.

Guide Running

Guide runners volunteer their time to helping blind people get __. By linking themselves together, the __ —impaired individual can feel safe while both work of a sweat.

___for the Homeless

Start-up Stuart Delivery and the Church Housing Trust collaborated last year in bringing clothing and healthy food to the homeless. Deliveries are mostly made by bike, so those who deliver keep fit while helping rough sleepers(无家可归者).

7 . Although it is difficult to make direct year-to-year comparisons because of increase in viewing on digital devices, the trend over the past decade is clear in numerous studies, including the Nielsen ratings. The average age of those who watch nationally televised Major League Baseball games has been _____ these years. Asked in a survey whether they _____ baseball, nearly two-thirds of those ages 18 to 36 said no.

Michael Haupert, a professor of economics at the University of Wisconsin ----la Crosse who studies baseball as a business, explains why many young people might be _____ by what to an older and more knowledgeable fan is one of the most exciting experiences in sports: a no-hitter. ” Failure is more ______ than success,” he says. ”If my students get a third of the answers right on their test, they fail. However, if a ballplayer gets a hit a third of the time, he’s often one of the _____ .” But watch an NBA game for 15 seconds, and you will likely see one team score.

It is not surprising that ______ the length of games----about three hours in recent years-----and increasing the pace of action has become a subject of discussion among those who love baseball. MLB commissioner Rob Manfred is strongly ______ of both. For the 2018 season, the league issued a set of new rules designed to do just that. Mound visits are limited. A timer countdown is designed to shorten the break between innings(局).

No one knows if any of these changes will significantly shorten games. According to MLB, the average length of a nine-inning outing this season has been three hours---about five minutes shorter than the 2017 average, itself the longest mean on record.

All of those proposed changes seem to ______ the point. I interviewed at least 100 semi-fans in their late teens and early 20s for my recent book. All considered themselves fans to some degree, though they ______   watched more than snatches—on iPads or smartphones. They told me it made no difference whether a game lasted two or three hours: they would not pay attention for _____ amount of time.

The historic May 14 Supreme Court decision allowing all states to legalize sports betting could have an impact on all this. More people will soon be able to gamble on sports while watching a game on their couch. But whether ______ gambling will attract more young people to baseball is a huge unknown. Many already gamble, both legally and illegally, on fantasy sports, but legalization will provide yet another ______ during games in real time. Will some states allow betting reports in broadcasts? Will it make the young more likely to bet on baseball than on other sports? Stay tuned.

I don’t know what will hook young people on baseball. But abandoning the game’s unique selling proposition---the timelessness that provides both suspense and great conversationhe educated fan -----is not the ______ . Baseball, Clark told me, is like a game of chess---and too many ______ - changes might turn it into something “more similar to a game of checkers.” Baseball may survive in spite of its challenges, precisely because it stands out and stands up against the short ______ spans that negatively affect every aspect of our culture, including politics and education. As Casey Stengel is reported to have said,” Never make predictions, especially about the future. ”

8 . Cali Scores a Goal

The players on both teams turned to __________ at it. A few girls pointed to it and cheered. The soccer game had nearly stopped.

She dribbled(带球) it between her feet, moving forward toward the net of the yellow team. By the time the other girls had __________ , Cali was positioned right in front of the net. The goalkeeper was __________ to one side, looking at the ice cream truck. She turned back __________ to guard the net as Cali kicked the ball hard.
