| The marvelous telephone and television
network that has now enmeshed the whole world, making all men neighbors, cannot
be extended into space. It will never be possible to converse with anyone on
another planet. Even with today’s radio equipment, the messages will take
minutes--sometimes hours--on their journey, because radio and light waves travel
at the same limited speed of 186, 000 miles a second. Twenty years from now you will be able to listen to a friend on Mars, but the words you hear will have left his mouth at least three minutes earlier, and your reply will take a corresponding time to reach him.

Primarily, of course, it blocked the Indian monsoon from reaching Central Asia at all. Secondly, air a A. analyze the possible causal links between Tibetan ecology and society B. describe the social organization of typical Tibetan villages C. describe Tibetan fauna and flora D. analyze the mysterious of the sudden appearance of the Himalayas [单项选择]
