Have you ever dreamed of visiting a planet in the Milky Way (银河系)? While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut eye. They would have to sleep for years.

European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month.

What seems like a science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don’t age. They have now moved on to the small, non-hibernating mammals (哺乳动物) like rats.

A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex (复杂的). "It’s like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy’s University of Pavia．Just like bears and frogs, the hibernation of human beings would cause a person’s metabolism (新陈代谢) to lower so they would need less energy.

Medical research, however, is just half of a space flight hibernation system. There is a challenge of designing a suitable protective shelter (栖身所). Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (监控) life functions and serve the physiological needs of the hibernator.

According to Ayre, the six-person Human Outer Planets Exploration Mission (使命) to Jupiter’s moon (木星的卫星) Callisto could be an opportunity to use human hibernation. The mission aims to send six persons on a five-year flight to Callisto, where they will spend 30 days, in 2045.

With eco-tourism on the rise, eco-hotels are fast becoming the darling of the travel industry. These days, however, staying at an eco-hotel doesn’t necessarily mean vacationing in a tree house in the Costa Rican jungle, although that is certainly a choice.
The majority of eco-hotels fall into one of several categories: hotels and resorts that conserve ecologically important habitats; “green” hotels that reduce, recycle, minimize waste, and protect water; sustainable hotels that harvest food from gardens on the hotel property or get part of all their power from renewable energy; hotels that encourage community involvement such as guests taking part in trail clearing; and hotels that offer some form of environmental education to their guests.
As such, eco-hotels are a various group. Stylish urban hotels like the Willard Inter-Continental Washington focus on energy conservation whereas the Rosario Resort＆Spa on Orcas Island in Washington State offers a wildly popular “green” vacation package where guests can “take a hike, clear a trail”.
No matter what you call them, eco-hotel, eco-lodge, eco-resort, or green hotel, they’re part of the “greening” of the tourism industry.
Part of what drives this greening of the hotel industry is no doubt competition. Going green is yet another way to distinguish a hotel from the mass of other excellent hotels that consumers have to choose from. But for many hotels, it’s also part of their philosophy. With the concept of “going green” firmly rooted in consumers’ minds, eco-hotels have taken it to the next level, and whether or not money is the driving factor behind the greening of the hotel industry doesn’t matter so much as it’s good for the planet.
【小题1】The underlined part in the first paragraph means _______.

Betty and Harold have been married for years. But one thing still puzzles（困扰） old Harold.

How is it that he can leave Betty and her friend Joan sitting on the sofa, talking, go out to a ballgame, come back three and a half hours later, and they're still sitting on the sofa? Talking?

What in the world, Harold wonders, do they have to talk about?

Betty shrugs. Talk? We're friends.

Researching this matter called friendship, psychologist Lillian Rubin spent two years interviewing more than two hundred women and men. No matter what their age, their job, their sex, the results were completely clear: women have more friendships than men, and the difference in the content and the quality of those friendships is "marked and unmistakable."

More than two-thirds of the single men Rubin interviewed could not name a best friend. Those who could were likely to name a woman. Yet three-quarters of the single women had no problem naming a best friend, and almost always it was a woman. More married men than women named their wife/husband as a best friend, most trusted person, or the one they would turn to in time of emotional distress （感情危机）. "Most women," says Rubin, "identified（认定） at least one, usually more, trusted friends to whom they could turn in a troubled moment, and they spoke openly about the importance of these relationships in their lives."

"In general," writes Rubin in her new book, "women's friendships with each other rest on shared emotions and support, but men's relationships are marked by shared activities." For the most part, Rubin says, interactions （交往） between men are emotionally controlled -a good fit with the social requirements of "manly behavior."

"Even when a man is said to be a best friend," Rubin writes, "the two share little about their innermost feelings. Whereas a woman's closest female friend might be the first to tell her to leave a failing marriage, it wasn't unusual to hear a man say he didn't know his friend's marriage was in serious trouble until he appeared one night asking if he could sleep on the sofa."
