     Manhattan is the heart of New York City. It is really an island, which is only 13 miles long and 2 miles

wide. Seen from the air, it look like a long finger. From the sea it is just like a picture we often see.

     Manhattan has some wonderful sights. What is the easiest way to see them? First, get a map of New

York City, which is often supplied free at gas stations and tourists offices. You can take a bus tour, but a

better way to see the sights is to walk, and you'll walk with your head thrown back so that you can look at

the tall buildongs rising like steep cliff(悬崖) on_____ of the streets.

     It is not easy to get lost here. The streets of New York from squares called blocks. Nearly all the streets

are in the straight lines, running from east to west. Those from north to south are called avenues. Most of the

avenues and streets have only numbers. The famous fifth Avenue is the dividing line between the east and

west in Manhattan. Here you'll see the Empire State Building. On the 102nd floor, over 1,400 feet above the

ground, it is possible for you to see the area in which one in ten of all the people in America live. You can also

look down at the other huge skyscrapers, the United Nations' buildings, the Statue of Liberty (自由女神像) in

the harbor, Broadway---the longest street in the world but not the straightest, and the greatest ships in the

world's biggest port.
