Have you ever dreamed of visiting a planet in the Milky Way （銀河系）? 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（冬眠） experiments．The study may help them understand whether humans could ever sleep through the years it would take for a spaceflight 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 （哺乳動物） like rats．

A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex．"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 （新陳代謝） to lower so they would need less energy．

Medical research, however, is just half of a spaceflight hibernation system．There is a challenge of designing a suitable protective shelter．Such a shelter would provide the proper environment for hibernation, such as the proper temperature．It would also have to monitor （監(jiān)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 （木星的衛(wèi)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．

Can you imagine your parents choosing your husband or wife for you? And can you imagine not setting eyes on him or her until your wedding day? This situation is common in India, the Middle East and many parts of Africa．  1   We don't realize that people in other places often get married in very different ways ---and with different motives（動機）．

  2  A marriage provides a safe and stable home for the husband and wife．It also joins two families, which benefits the couple's parents and makes them happy．Marriage also brings children, making sure the couple will be taken care of in old age．Because a marriage is important for the whole family, some cultures don't let young people choose whom to marry．

Just as there are many different reasons for marriage, there are also many different wedding rituals（儀式）．  3  In a typical Western wedding, the bride seeks good luck by wearing "something old, something new, something borrowed and something blue．" Something old represents the past．Something new represents success in the future．Something borrowed reminds the bride she can get help from her friends and family．  4 

In Poland, one wedding tradition is not only lucky, but also very practical．The wedding guests pin money to the bride's dress while she is dancing．The money is meant to bring luck and to help the young couple build their new life．In Bermuda, the young couple plants a tree in the yard of their new home．Once they move in, they take good care of the tree , making it grow and blossom．The planting of the tree is a good metaphor（隱喻） for marriage．  5 

A．Every culture has its own ways of bringing good luck to the happy couple．

B．A truly good marriage is something that grows with care．

C．In the United States, parents do not arrange marriages for their children．

D．And something blue reminds her to be true to her husband．

E．Marriage customs around the world often differ from our own．

F．In many countries, marriage is a practical matter．

G．Different countries have different cultures．
