【简答题】
My name is Deirdre Veneracion and I am a paraglider pilot. I’ve been paragliding since I was 11. My dad and I arrive at our local fly site on a June morning. We meet our instructor and spend the first 20 minutes watching the wind cycles. I go through my pre-flight steps and turn on my radio. At last, I take a step and feel the ground under me fall away. I feel the pressure of my weight on the canopy ( 伞衣 ). After 15 minutes of playing with the wind, my father radios me from the place where he is about to take off. “How is the wind?” “Perfect!” I say. Dad takes off behind me. I have done almost 100 flights and yet every flight amazes me just as much or even more than my first. I love the unpredictability of each flight. Every flight is different. After 15 minutes, I decide to land. Now, I’m over a rice field. It is a much smaller landing than most landing zones but it’s possible. Out of nowhere, I feel my canopy become unstable ( 不稳定的 ). It loses pressure and falls directly in front of me. I am falling. I have butterflies in my stomach. I pull my brake ( 制动器 ) line, in the hope that my wing will get pressure again but it doesn’t. I look towards my dad and see that he is also in trouble. It’s as if we were inside a washing machine being thrown up and down. I won’t make it to the landing zone in front of me. To my right is a narrow ( 狭窄的 ) stream with hardly any water in it. I make my decision: the narrow stream is my best chance of landing safely. As I touch down, I check on my dad and am glad to hear that he is fine. Local villagers come to check on me but, surprisingly, I am uninjured. This is one of those times when we are reminded that no preparation can prevent Mother Nature from surprising us. 24. What does the author do before taking off? A. She has a talk with her father. B. She watches the weather. C. She turns off the radio. D. She gives instructions. 25. What does the attraction of paragliding lie in the author’s eyes? A. The pleasant wind. B. The success of each flight. C. The excitement of landing. D. The uncertainty of each flight. 26. What kind of feeling does the underlined sentence in Paragraph 5 probably show? A. Nervousness. B. Happiness. C. Anger. D. Luck. 27. What happens in the process of the author’s landing? A. She hurts herself. B. She asks her dad for help. C. She sees a washing machine below. D. She changes her mind about the landing site.
