     Should we try to contact and make friends with other beings in the universe? Certainly not，says British physicist Stephen Hawking．

     “If aliens（creatures from other planets）ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans,’’ said the 68-year-old disabled scientist in a new Discovery documentary (纪实性电视节目) on April 25．

     The program pictures an imagined universe where other life forms in huge spaceships hunt for resources after using up all those on their home planets．

    “Such advanced aliens would perhaps become nomads(游牧民)，looking to conquer and colonize whatever planets they can reach，”warned Hawking．

     On the probability of other life forms existing, he says, “To my mathematical brain, the numbers alone make thinking about aliens perfectly reasonable.”

     Hawking’s concerns have frightened some people and been met with disagreement from other researchers．Paul Davies, author of the book Renewing Our Search for Alien Intelligence，thinks Hawking’s reasoning is wrong.

     He argues that since Earth is about 4.5 billion years old，if intel1igent life is likely , communities of other beings may have been there for a very long time．

    “If resources are the factor, then at least one group of aliens would surely have visited Earth as a destination mil1ions of years ago．

     Even if other life forms do come to Earth in the near future, Davies believes comparisons with are wide of the mark(离谱的).

You can speak to people on other side of the earth over the telephone with help of a satellite. They can help to take photos on the earth and produce maps. Some pictures taking by satellites show us the exact place where different metals can be found. They can also tell the differences between healthy plants or poor ones. This is a great help to the scientists work in forestry and in agriculture. Satellites benefit by out daily life. For example, satellites for broadcasting are used to sending radio and TV programmes from one part of the world to other. It is the satellites to make our world seem smaller.

I still remember the morning. My father suddenly wake me up at about 5 and the sky was still gray. I jumped out bed surprised and extreme happy, for we were going to get a book! When we drove to the bookstore, many people were already waiting there. We waited for our turn at about 8:30. I was overjoyed when I got a book, not only because of the book themselves, but also of the love from my father. Never before had I felt such a love from him, because of my father, I believed then, had always been busy with his own work. That was “Harry Potter” that helped I feel the deep love from my parents!

My swimming experience is extreme interesting. There was a time when I swim like a rock. This went on till one day when I was fishing with a friend of mine at nearby pond. I slipped into one. Had my friend not come to my rescue, I would have been drowned. Ever since then, I had come to know the importance of learning to swim. I didn’t attend at any training class but learned it all by myself. Strange to say, I have difficult swimming at all now. Though the way I swim look awkward (笨拙的), at least it can keep me from floating. Thinking of this, I feel quiet satisfied.
