New york
Americans great metropolis.

The city of
New York has many claims to greatness. It is one of the world largest and
busiest ports. It is the financial centre
of the world and the first in
manufacturing among United States cities .As the headquarters of the United
Nations are in New York, it is a world capital in a sense.
New York is
also a great cultural center. It ranks high i the fields of education. art, theater
,ballet, music, publishing, and fashion
. Although it is one of the youngest of the worlds great cities (founded in
1626), it surpasses all of them in wealth and influence.
Like other
great cities, New York has many
magnificent buildings . It is most famous , however, for its unique skyline.
Its towering skyscrapers are massed closed together. Seen against the sun or
lighted at night , they make an awe- inspiring view. For many people outside
the United States , New Yorks skyline and the Statue of Liberty in its harbor
are symbols of the progress and spirit of America.
New York
rivals Tokyo and Greater London in population. New Yorks land area is Limited
to about 320 square miles, but it is the nucleus if an enormousurban
area .

The city is made up of five political divisions , called boroughs. Each borough is
also a county. Two are islands ;two are
on Long Island. Only the Bronx is on the mainland , is three sides being
washed.
The borough
of Manhattan occupies Manhattan Island. A web of bridges and tunnels links it
with the other boroughs and with New Jersey . It is the smallest borough, but it is the heart of the
city. It is the ‘Little old New York’.
The Dutch who founded it called it New Amsterdam. The English took it and
renamed it into New York. It had annexed
all the Bronx by 1895. In 1889 it joined other
counties to form Greater New York
and became the Borough of Manhattan.
The Borough
of Queens and the Borough of Brooklyn occupy the western end of Long Island.
The East River and Long Island separate them from Manhattan and
the Bronx. Queens is the largest borough. Brooklyn ranks first in population.
The borough
of Richmond is usually called by its old Dutch name, Staten Island . It is the
least developed of the boroughs. Because until 1964 , when the Verrazano-
Narrows Bridge was completed, it had no bridge or tunnel connection with the
rest of the city
