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 slight16before setting down. High desert winds had17the airport to close all but one runway. He said that we would be circling the city for a few minutes waiting to18. We were also told to remain in our seats meanwhile with our seat belts fastened19there might be a few bumps(µßô¤)£®We11£¬that few minutes turned into about four—five minutes£¬including a ride that would make a roller coaster(¹ýɽ³µ) pale by comparison.

The movement was so fierce that several passengers felt _20and had to use airsickness bags. As you might guess, that’s not good thing to have happen in a(n)__21space because it only serves to increase the discomfort of the situation.

Having understood this£¬I took a deep breath and 29back into my seat£¬pretending I was really on a roller coaster. I smiled for the rest of the flight. I even 30 to giggle once or twice ,much to the chagrin(·³ÄÕ)of the man sitting next to me holding the airsickness bag.
