Chicago
Chicago, lying in the east of the USA, is the rather young American city. It was almost completely rebuilt after the Great Fire of 1871. One's first impression of the city may include streams of cars running to-and-fro on the highways, skyscrapers and the wide green water of Lake Michigan, which lies to the northeast of the city. The area of the city is over 228 square miles with a population of about 3 million.
The climate of Chicago on the whole is almost the same as that of Beijing with rather hot days in summer, colorful and fresh days in fall and icy but often clear days in winter. The spring in Chicago is a little changeable in temperature. For instance, I saw a snowfall in early April this year while some of the flowers were already in full bloom. Chicago is also famous for its frequent strong winds, and as a result has got the name of "the Windy City".
Chicago is a rather young American city because.
A．it was completely rebuilt in the late 19 century
B．there are smaller areas in Chicago than in Beijing
C．its population is in fact rather small
