Recently，I flew to Las Vegas to attend a meeting. As we were about to arrive，the pilot announced with apology that there would be a slight             before setting down. High desert winds had       the airport to close all but one runway. He said that we would be        the city for a few minutes waiting to      . We were also told to remain in our seats meanwhile（同时） with our seat belts fastened      there might be a few bumps(颠簸)．Well，that few minutes turned into about four—five minutes，including a ride that would make a roller coaster(过山车)     by comparison（比较起来）.

The movement was so fierce(猛烈的) that several passengers felt      and had to use airsickness（晕机） bags. As you might guess，that’s not good thing to have happen in a(n)      space because it only      to increase the discomfort of the situation.

  About twenty minutes into the adventure，the entire airplane became very   .

There was now a sense of anxiety and fear that could be     noticed．Every passenger simply held on for dear life …except one. A     was having a good time! With each bump of the__ ___he would let out a giggle(咯咯的笑)of delight. As I observed this，I        that he didn’t know he was supposed to be afraid and worried about his      .He neither thought about the past nor about the future .Those are what we grown—ups have learned from      .He was     the ride  because had not yet been taught to fear it. Having understood this，I took a deep breath and          back into my seat，pretending（假装） I was       on a roller coaster. I smiled for the rest of the flight. I even       to giggle once or twice ,much to the chagrin(懊恼)of the man sitting next to me holding the airsickness bag.
