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 Earth? These are questions that, understandably, are very often asked.
Perhaps the best answer lies in our genetic makeup (基因构成) as human beings. What drove our ancestors to move from the trees into the plains, and on 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 tendency 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 knowledge, 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 or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications 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 danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.
While 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.

   根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
When you’re all comfortable and warm, watching the snowflakes pile up outside, you might wonder, what about the poor animals? No fire. No cocoa. No blankets.   36   
Well, it’s really people who aren’t designed to live in cold climates.   37   Geese have built-in down comforters. Bears have fur coats. Robins just fly south. But look at people. No fur. No feathers. No fair! And not everyone can jet off to Florida when it snows.
  38   Mainly, our big brains. Still, it’s taken us a long time to figure out how to cope with cold weather, and along the way we’ve borrowed a few tricks from the animals, too.
When you put on a jacket, you feel warm. Why? Because your jacket traps the heat your body produces. Your body uses the food you eat as fuel to stay warm.   39   Active muscles burn more fuel and produce more heat. That’s why you shiver when you’re cold. By shivering, your body is doing its best to get your muscles moving and warm you up.
  40   Even in the coldest weather, your brain needs lots of warm blood. That’s one reason why your feet and hands get cold --- your body is sending heat to your brain. If you put on a hat, you will find that your feet and hands get warmer. 
A. How do they stand it?
B. It can no longer trap a layer of warm air.
C. If you run or jump around, you feel even warmer.
D. So what do people have to help beat the cold?
E. Animals have lots of cool ways to survive the winter. 
F. That’s because water carries heat away from your skin.
G. The most important part of your body to keep warm is your brain.

What a busy day! The three boys were fed, bathed and changed into their nightclothes. Mary had   41   them a story and finally they were asleep. “Babysitting (照看) the three boys aged eight, six and four is extremely  42  ,” she thought.
“Sleep,” she considered, “if only I could!” But she had difficult homework to complete. Leaning back, she   43   her feet onto the sofa to get comfortable. Whoever said babysitting was a(n)  44  way to make money obviously hadn’t met the three boys, she thought. The television was on, the room was warm, and the lights were dim. Mary’s   45   felt heavier and heavier. I mustn’t sleep, she thought—which was   46   what she did, of course.
