4 . I’ve never been much of a jogger, but might I make a decent plogger? “Plogging” is a(n) ________ of “plocka upp” with “jogga”, the Swedish for “pick up” and “jog”. The idea is that you ________ litter while out running and the ________ has been growing in popularity in Sweden.

“It’s good for both the ________ and ourselves,” says Anna Christopherson, the 43-year-old Swede who runs Edinburgh’s first plogging group. “It’s very ________ for the body to combine running with squatting (蹲下) to lift rubbish.”

Seven of us ________ in the city for the run. We rush up Leith Walk, our rubbish bags ________ in the evening wind. “Quite competitive, isn’t it?” says Struan, an accountant. He ________ to a bin, muscles bulging (鼓起), to pick up a leaflet.

Within 10 minutes, our bags are filling up. It’s amazing — and ________— to see how much ________ is lying on the streets. A passing walking tour gives us some ________ looks, but we ploggers, lost in a world of plogging, carry on ________.

After an hour, I’m tired and ________, but feeling good. The city is a little ________ thanks to these ploggers. Anna is not satisfied, though. Our ________ have made no difference to her pet hate: chewing gum (口香糖) stuck to the paths. “You need a steamer to get that off,” she says. “And I’m not going to run with a steamer any time soon.”
