AThe Great Barn AdventureOne morning when I was 11, I explored the towns abandoned round grain barn(谷仓). I found a chained sliding door that was wide enough for me to pass through.Inside, there was a heavy smell of dead mice in the dark. After my eyes adjusted, I noticed a shaft (升降机井) that rose all the way to the top of the barn. On one side was a one-man elevator with a long rope and roller.I stepped onto the platform and gave the rope a drag and the elevator began sliding up the shaft, but stopped halfway. After a brief panic attack, I noticed holes in the wall at regular intervals, forming a ladder. For reasons known only to an 11-year-old, I decided it would be better to go up than down. So, with shaking hands,I began climbing the wall.After what seemed like forever, I reached the top of the shaft. I stood up, dusted myself off and foundabsolutely nothing of interest. It was just an empty room with a ladder leading up to the roof. I climbed all the way up here for this? Then I noticed a fire extinguisher(灭火器),which Id always wanted to shoot off. So this was the chance of a lifetime. I tried it, and, much to my surprise, the thing worked! It shot out a thick cloud of powder that instantly filled the room. I couldnt breathe. I was going to choke to death, and theyd probably never even find my body.Luckily, I remembered the ladder to the roof. I climbed up, popped the straw roof and saw a bright blue sky.I suddenly realized the dust and powder pouring out of the top could draw attention. So when the dust had settled, I climbed down and slipped out of the chained door. Im not sure if I was more excited about being alive or about not being caught, but I ran all the way back home.21. When the author got inside the barn, he _______.A. noticed a man on the elevatorB. opened the chained sliding doorC. saw many dead mice in the darkD. found a shaft leading to the top22. Which of the following is the right order of the authors adventure?a. The elevator stopped halfway.b. He entered the round grain barn.c. He climbed to the top of the shaft.d. He found a fire extinguisher and shot it off.A. b-a-c-dB. b-c-a-dC. b-a-d-cD. b-c-a-d23. After getting out of the chained door, the author might feel _______.A. inspiredB. relievedC. surprisedD. disappointed24. From the passage, we can learn that the author was probably a boy full of _______.A. passionsB. dreamsC. curiosityD. imaginationBWere always looking for well-written reviews of books, music, movies, television shows, websites, video games and other products.
