Frank was walking down the 6th Street on a hot sunny day when he saw smoke coming out of the street. He could         the smoke, and it was getting thicker. Seeing the smoke coming out of a storm drain(雨水沟), Frank called the fire department immediately. “The storm drain is        fire!” he said. The fire department asked for his whereabouts and he said he was near the 6th and Main. They said they         be right there to investigate the situation. Frank needn’t to go anywhere, so he waited for the         to arrive. He was curious what could be burning beneath the street. As far as he knew, there wasn’t anything beneath the street         concrete(混凝土). And everyone         that concrete doesn’t burn.
A fire truck arrived a few         later. “Are you the man who      ?” asked the driver. “Yes. ” Frank answered. By now Frank could not only smell the         but also hear crackling sounds, just like wood burning. The firemen didn’t seem to consider it an emergency. “       do you think it could be?” Frank asked the driver. “Oh, we know what it is. We have to         a problem like this every few months. It’s the homeless people in their “      ”. ”
Homeless people have been living under the streets for years.        their knowledge of the storm drain system, they         their own “houses” beneath the streets. These living areas have tables, mattresses, chairs, and sofas. The settlers often “borrow” electricity by connecting to a live wire above ground to         their own lights and even TVs underground. Either this         electricity or a cigarette can cause an occasional fire.
Frank watched         some firemen lifted a manhole cover (井盖) and went beneath the street with a fire hose (消防软管). Then a few minutes later, the         smoke turned white. Shortly        , the firemen reappeared with a        person who seemed to have just been woken up.
