阅读短文，回答问题 Jason and his father were going to a supermarket by car to pick up some apples. It had been an unusual day. The sky was dark but there were few clouds. As they drove up the street, there started to be a loud sound heard across the ground.
Jason's father immediately realized that a tornado(龙卷风) was coming. He stopped the car and told Jason to get out immediately. Jason and his father got out of the car and made their way to the closest building. By this time the wind was blowing harder, and it was hard to see or hear. Jason couldn't see his dad anymore. He also realized that he wasn't getting to the building fast enough. He was afraid he would be picked up by the wind and thrown into the air.
As he made his way towards the building, he noticed a field to his right. He could see an irrigation ditch (灌溉渠). He felt really afraid inside because he'd never been in a tornado before. His heart began to race and he could feel sweat dripping down from his face. In a panic, he started running towards the ditch as fast as he could. He stumbled(绊倒)a bit as he climbed down into it, but soon he was lying flat on the ground, hiding inside. He could hear his heart beating even more loudly and felt his whole body shaking.____
After a while, the wind died down and the loud roaring sound was gone. Jason slowly lifted his head and nervously looked around. What he saw was a great mess. Jason could hardly recognize the buildings in front of him because of all the damage.
He stood up and with his legs shaking and walked to the building. Once there, he pushed the door open and went inside. It was a public building owned by the city. It was empty, but Jason could hear noises further inside. He walked into the large room and saw his dad. He ran across the room and gave him a big hug.
"Jason! How are you? I've been so worried about you!" said his father. "I couldn't find you anywhere!"
Jason breathed a sigh of a relief(松了一口气) and sat down. He did have a story to tell!
