C完形填空。(30分)

   Are we alone in the universe? Or is there 1 on Mars?

   Ever since people first 2 up into the night sky,there’s been a question that has bothered us all.From the smallest 3 to the world’s greatest astronomers,all have 4 ,“Are we alone in the universe?”

   The question comes to me strongest at 5 ,looking up at the stars and looking at all those little 6 of light and wondering “This is a galaxy (星系) full of life,or is this it?”

   It’s the question that societies often have been asking 7 the ages. We really just want to know how we got here. Why do we exist? Are we the 8 sign of life?

   This 9 for life elsewhere in the universe is perhaps the greatest scientific question of all. But so far most efforts have 10 on just one planet.

   Searching for life is a difficult job. We d like to be 11 to travel to all these worlds far away. Unfortunately,12 of them are very good in terms of prospecting for biology (勘探生物) . The best one is probably Mars.

   Mars is just 60 million kilometers away.

   Mars is important because it’s close by. It’s our 13 neighbour to the Earth. And we'd like to see if life is there9 because if we can find life in 14 places in our solar system (太阳系) ,we know that life isn t just on the Earth. It's much more 15 that life fully exists elsewhere,perhaps in other solar systems,other parts of the universe.
