完形填空Ahhh, summer. Time to relax. You cannot have complete rest if you ___1___it too seriously. But taking vacations seriously is exactly___2___we Americans seem to do. In the same way our kids' free time is now packed with activities, we adults have turned vacations into "active leisure." Anytime you try very hard to relax, that's active leisure. Our vacations___3___with an agenda, a purpose. We're visiting family, attending weddings, going camping, and making sure we ride that roller coaster-no matter how long the line is. We Americans are so active in our leisure___4___we commonly complain we need a vacation from our vacations. We leave home___5___; we come back exhausted. That's why many of us have decided not to go. Americans are___6___a few vacation days (14 days, on average) compared with other developed countries, but ironically, we don't even use them. The average American will leave four vacation days on the table this year, which adds up to a total 574 million days of___7___vacation. Our relationship to relaxation seems contradictory. We spend more money than anyone else in the world on leisure-fully one-___8___of our income-and yet at the same time we are No. 1 in the world at not taking vacations. One of the top reasons given for not taking a vacation is that it's too much extra work. We have to get___9___of our work in order to leave, and then we have to catch up on our work upon our return. The longer the vacation we take, the bigger the stumbling blocks appear. So only 14% of Americans will take a vacation two weeks or longer this summer. Bottom linE、it's simply become too stressful to relax. We Americans take our time off so seriously that you can now get a Ph.D. in leisure studies at Penn State and 17 other famous universities. That's right-a doctorate, not just a bachelor's. It's such an up-and-coming field in academe that there is an actual shortage of___10___educators. We don't have enough people to teach leisure. I am tempted to make a joke about this, but I don't want to get the wrath of the leisure scientists. They'll beat me up with chairs.
