New York is one of the most exciting cities in the world.

You might want to do some shopping in New York. Fifth Avenue is probably New York’s most famous shopping street, but if you go, be prepared to "window shop" only. This is shopping for the rich. There are other, less expensive shopping areas nearby, and you’ll soon find famous stores such as Bloomingdale’s, Macy’s and FAO Schwartz. And if you’ve brought your rollerblades(滑板), then a visit to Central Park is a must. This is a large, open park right in the middle of Manhattan, but if you thought that people came here to relax, then you’d be wrong. Nobody sits in Central Park: they run, jog(慢跑), and most of all they rollerblade.

When you leave New York, you might be tired, but the one thing you won’t be is bored!
