Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on the earth? These are questions that, understand?ably, are very often asked.

Perhaps the best answer lies in our genetic make-up(基因构成)as human be?ings. What drove our ancestors to move from the trees into the plains, and into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tend?ency to expand wherever possible.

Nearly every successful civilization has explored, because by doing so? any

dangers in surrounding areas can be identified and prepared for. Without knowl?edge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.

Exploration also allows minerals and other potential(潜在的)resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge and technique have been acquired through exploration. The technique may have medical applica?tions which can improve the length or quality of our lives. We have already benefi?ted from other spin-offs including improvements in earthquake prediction, in satel?lites for weather forecasting and in communication systems. Even non-stick pans and mirrored sunglasses are by-products(副产品)of technological developments in the space industry!

While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The clanger exists? but knowledge can help human beings to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.

While the earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.

   The Johnson family from England believe they are lucky to be alive af?ter surviving an incredible incident off the coast of Australia. The John?sons had been  that they might see some whales when they were  2   a yacht―a large expensive boat for a 10-day sailing    3     around the Whit?sunday Islands.    4    , they had no clue just how     5     their viewing would be. Two hours into their journey a nine-metre-long humpback whale    6     out of the ocean and crashed into their boat before returning to the water.

Mark Johnson,the eldest son, was sailing the yacht when he heard an immense bang and a thud(重击声).He  7  thought the yacht had hit a rock. However, when he looked up,he saw the whale  8  down the deck of the boat. He told the reporters,"We were staring into its right eye. It was a very   9   moment. The eye was about the  10   of a dinner plate. It was huge."

 11  for the Johnson family,no one was hurt,but the yacht suffered  12  damage. The whale had ruined the mast and rigging一-the pole and ropes which hold the  13   ―and so the family was left  14  at sea, 10 miles from the shore. The 15   equipment was also damaged, but fortunately they had a cellphone and were able to call for help.

   Why the whale jumped onto the yacht is a  16  , but the family thinks that maybe the boat had not  17  sailed between the whale and its baby calf. Perhaps the whale was trying to  18  its calf when it jumped,hitting the yacht by chance.

Whatever the reason, people are completely  19  that this incident hap?pened. There is over 135 million square miles of ocean, so what are the  20  of a whale jumping onto a 30-foot-long yacht? The chance of something like this happen?ing is minuscule,but it just shows that life is full of surprises.
