Everyone needs to know how to prevent a fire. It is also important to know what to do when it     1    （break）out .

Every year, over 11, 000 people     2    （kill）or injured in house fires. These fires could have been avoided. Smokers who are     3    （care）cause about 200 deaths and over 6,000 fires. More than half of those     4     die in fires are poisoned or harmed by smoke.

If fire happens, do not attempt to fight the fire unless it is small. Try putting out a small fire with water. If     5     fire has spread or if the flames are more than 20 inches high, shut the door on it. Warn everyone else in the building and tell them to get out. You should leave and dial 119for the fire department.

Before     6    （go）into a room, check the door. If the handle or the door is hot, do not open it! Instead, put clothing or a wet towel at the bottom of it to keep smoke out. If the door is not hot, open it     7    （slow）. If there’s a rush of smoke or heat, close it again and shout to warn     8    （other）in side.

Now open the window and shout “Fire!”. See whether you can drop safely to the ground. Use this     9     your escape course if you can. If you are not on ground level, break your fall by pushing a mat out first. Lower yourself at arm’s     10    （long）before dropping. Once outside, stay outside and make sure the fire department is called.

Then, he ________ the teen out of a back window and dragged him to ________ "before the entire car exploded", the police stated.

Languell thinks about that day often. Displaying the sort of empathy（感同身受）that ________ him to help, he told WAGM-TV, "My ________ goes out to 'Thompson'. When you are that close to that level of hurt, you feel it so directly."

9 . “I wish we hadn’t come on this trip!” Jeff’s voice echoed across the narrow canyon （峡谷）. His father stopped, breathing heavily. “This is hard on you, but you’ve got to come through with courage!” He gently placed his hand on the boy’s shoulder. “Now, I don’t know if I can make it without stopping every so often. You’re young, but you’re strong and fast. Do you remember the way back from here to the road, if you had to go alone?”

Jeff flashed back to the painful scene of Mark, his seventeen-year-old brother at their campsite. He was bitten by a snake yesterday. This morning he couldn’t move, and the pain got worse. He needed medical attention right away. They had left their phone in the car, and it must have been out of power by then. Leaving Mark at the campsite and seeking help was their only choice.

“Jeff, could you do it?”

Jeff looked to the end of the canyon, several miles away. He nodded and a plan began to take hold in his mind. “What is the name of that little town we stopped, Dad??” There must be a hospital there.

“Flint. We parked at the side of the road a few miles out of Flint.”

Jeff nodded. Then they continued climbing. Stone by stone, they made their way up the canyon. Gradually, Jeff’s father grew smaller and smaller in the distance. Jeff waved to him and then climbed toward the road. Two hours later, he finally reached the road and struggled toward the town, almost exhausted.

“Can’t stop.” He thought. “Mark’s in big trouble. Keep going.” Suddenly, he saw a truck heading toward him. “Hey, mister!” He shouted, waving both arms. He began to jog toward the truck, and then broke into a full-speed run.

His chest was burning with every breath when the truck driver stopped by him. Jeff explained breathlessly. The driver reached for his cellphone as soon as he heard about Mark. “Better get the helicopter in there,” he said immediately. But Jeff wasn’t sure about that because everything got unclear and then went black and quiet.

Hours later, Jeff opened his eyes to find his father on a chair nearby. “You’re a hero, son,” his father said with a smile. “You had the helicopter sent into the canyon after Mark. I can’t tell you how happy I was when I saw it overhead. They got him to the hospital. He’s going to be fine soon. I’m so proud of you!”
