阅读理解。

     Most people, when they travel to space, would like to stay in

orbit for a few days or more. And this stands to reason, if you're

paying $ 20,000 for your trip to orbit!  So in order for tourism to

reach its full potential there's going to be a need for orbital

accommodation-or space hotels. What would a space hotel

actually be like to visit? Hotels in orbit will offer the services you

expect from a hotel-private rooms, meals, bars. But they'll also

offer two unique experiences: impressive views-of Earth and

space~ and the endless entertainment of living in zero gravity-

including sports and other activities that make use of this.

   The hotels themselves will vary greatly-from being quite

simple in the early days to huge luxury structures at a later date.

It's actually surprising that as later as 1997,very few designs for

space hotels were published. This is mainly because those who

might be expected to design them haven't expected lauch costs to

come down far enough to make them possible.

     Lots of people who've been to space have described vividly

what it's like to live in zero gravity. There are obviously all sorts of

possibilities for dancing, gymnastics, and zero-G sports. Luckily,

you don't need to sleep much living in zero gravity, so you'll have

plenty of time for relaxing by hanging out in a bar with a window

looking down at the turning Earth below.

      Of course all good things have come to an end, unfortunately.

And so after a few days you'll find yourself heading back though

you'll be much more expert at exercising in zero gravity than you

were when you arrived. You'll be thinking how soon you can save

up enough to get back up again-or maybe you should change jobs

to get to work in an orbiting hotel!
