I had a friend who visited me from out of town and I wanted to show him the CN Tower. It was one of the tallest structures on the earth. So I thought it would offer a(n) 1 sight. We were standing in line for 45 minutes to enjoy the 2 up to the watch point. When we got there, we went around the 3 of the tower and saw the hard wire fence 4 to the structure serving as a barrier. We went back inside to look for the glass floor that provided a direct view . As soon as both of us 6 , we stopped before walking onto it. We found that our legs began to 7 . I stopped for a minute considering the step, taking several seconds to 8 the edge before moving. And then I had a thought in my mind:“It is far 9 compared to any other floor in this building. There is no real danger to me — it’s 10 an illusion( 幻觉 ). Look at all the people standing on it, and think about those who have stood on it before.”I began to 11 that step onto the glass floor. I didn’t look down 12 not for a few minutes. I walked on the 13 and looked around and thought about how 14 the experience was. I even found myself jumping up and down. There was no 15 , and it was certainly an illusion. I considered how many things in our lives we 16 and exactly how many of them are actually illusions. I thought about all the things we 17 ourselves from doing because we have 18 ourselves into thinking there’s risk. I thought about all the things that I still have yet to do that appeared 19 ; I was glad to discover that although fear isn’t a stranger to me, my desire to live a life without 20 has a much stronger pull.
