On the day when the tornado hit, there was no sign that the fierce weather was on its way-—the sky was blue and the sun was high. The first warning my husband Jimmy, 67, and I, 65, got came around 9 pm from some news on TV Jimmy was watching. He ran upstairs to find me in our third-floor bedroom, and we changed the channel from the national television to our local Pensacola, Florida station.
Soon the tornado was on top of us. It was the loudest thing I had ever heard. The house shook, and the power went out. And the wind began to roar(呼啸)through the house,mostly through windows and our garage door. Everything was moving. And the back wall of the house came off and flew into the darkness outside. We had three flights of steps to get to the storeroom down there, the relative safety of the first floor.
I didn't know how or if we could make it down the steps. It felt as if there was no floor as the wind lifted me off my feet. As we finally reached the last flight of steps, our front door blew open. Suddenly, a three-foot-long tree branch flew over our heads, missing us by inches.
By the time we reached the storeroom, the tornado had been over us for about a minute. Jimmy pushed me down into the storeroom, but he couldn't get himself inside because of the wind. I held Jimmy's arm as the tornado blew the door open. My knees were hurt by pieces of glass, but I felt no pain. If I had let go,Jimmy would have flown right out of the house.
All of a sudden, Jimmy was lifted off his feet. I thought he was gone. But then everything stopped. He landed on his feet. In those first quiet moments, I couldn't believe it was over. Our neighbors said the storm lasted four minutes. In that time, four of the twelve town houses in our unit were completely destroyed. Luckily, none of us was seriously injured.
1. Where did the couple learn about the coming fierce weather
A. From the dark sky. B. From the text sent by their neighbors.
C. From the radio station. D. From the news report on TV.
2. Why did the couple try to get to the storeroom
A. It was safer there. B. They went there to get something.
C. They liked to stay in a storeroom. D. They tried to hide from their neighbors.
3. What do we know about Jimmy when the author reached the storeroom
A.He flew out of the house. B. He was in great danger.
C. He was seriously injured. D. He got inside the storeroom.
4. What is the best title for this text
A. The Wind Roaring Through the House B. A Couple Stopping a Disaster
C. A Couple Keeping Alive in a Disaster D. The Tornado Hitting Florida

Earthquake rescue robots experienced their final tests in Beijing. Their designers said with these robots, rescuers would be able to buy more time to save lives during an earthquake.
This kind of robot looking like a helicopter is a flying robot. It's about 3 metres long, and it took about4 years to develop the model. Its main functions (作用) are to collect information from the air, and send goods of up to 30 kilos to people trapped by an earthquake. It has a high-definition 360-degree panoramic(全景的)camera.It can work day and night and is also able to send the latest pictures from the quake area.
Dr Qi Juntong, a researcher at Chinese Academy of Sciences, said, "The most important feature of this flying robot is that it doesn't need a distant control. We just set the destination information on it, and then it takes off, and lands by itself. It flies as high as 3,000 metres, and as fast as 100 kilometres per hour."
This robot has a different function—it can change as the environment changes. Its main job is to search for any sign of life in places where human rescuers are unable to go. As well as a detector(探测器)that finds victims and detects poisonous gases, a camera is placed in the 3-metre-long robot, which can work inthe dark. Another use for the rescuers is the supply bot. With its 10-metre-long pipe, people who are trapped in the ruins will be able to get supplies including oxygen and liquids.
