The heated air above a fire rises in a pillar of smoke and burnt gases, pulling fresh air in from the sides to replace it. Firefighters use this fact when they "fight fire with fire." They start a fire well in front of the one which they are fighting. Instead of traveling on in front of the huge fire, the smaller fire is pulled back toward it by the updrafts of the larger blaze. As it travels back to meet the large fire, the smaller backfire burns away the fuel that the forest fire needs to survive.
Even when a backfire has been well set, however, the fire may still win the struggle. The wind which the firefighters used to help them may now become their enemy. When the backfire meets the main fire, before both die for lack of fuel, there is tremendous flame, great heat and wild winds. A strong gust may blow the fire into the treetops beyond the area, giving the fire new fuel and a new life.
This passage focuses on ______.
A.how fires start
B.damage caused by fire
C.the fascination of fire
D.fighting forest fires

The Smokey Bear(护林熊) fire prevention program has resulted in a savings of $20 billion on all federal(联邦的), state and private forested land(私有林地).

第9题
When he got up in the morning, it looked, as though the fire was dying down, though he could still see some flames. So he set to work to tidy his room and put his things back where he wanted them. While he was doing this, Jane came in to say that she had heard the fire was a bad one:three hundred houses had been burned down in the night and the fire was still burning. Pepys went out to see for himself. He went to the Tower of London and climbed up on a high part of the buildings so that he could see what was happening. From there, Pepys could see that it was, indeed, a bad fire and that even the houses on London Bridge were burning. The man of the Tower told him that the fire had started in a baker's shop in Pudding Lane; the baker's house had caught fire from the overheated oven and then the flames had quickly spread to the other houses in the narrow lane. So began the Great Fire of London, a fire that lasted nearly five days, destroyed most of the old city and ended, so it is said, at Pie Corner.
What is the passage about?
A.The Great Fire of London.
B.Who was the first to discover the fire.
C.What Pepys was doing during the fire.
D.The losses caused by the fire.

根据下面内容,回答题:
People often speak of fire as though it were a living creature——It grows, dances, needs oxygen,feeds on whatever it can find, and then dies. And when a forest fire rages out of control, threatening human lives and homes, it must be fought like a "wild animal. " The fight is often desperate, since firefighters" best efforts may be dwarfed by the fury of a large fire. But the fire"s own traits can be used
against it.
