There was a big fire in one office building in our neighborhood at about nine4 o’clock last night.Many firemen and fire engines came.In the beginning,we saw flames with thick black smoke coming out from the sixth floor; and we also heard the explosion of the gas tank mixed with the noisy sounds from shattering windows.Soon the fire spread one by one to the floors above,and finally reach the top floor.Some aluminum window frames and some brick walls meted and collapsed from the heat.
