完形填空。 You Can't Be Replaced As a teenager, I felt I was always letting people down. I was rebellious (叛逆的) on the outside, 1 on the inside I wanted people to 2 me. Once I left home to hitchhike (搭便车) to California with my friend Penelope. The trip wasn't 3 and there were many times I didn't feel safe. One situation in particular left me 4 for still being alive. When I returned home, I was different -not so outwardly (外表上) sure of myself. I was happy to be home. But then I noticed that Penelope, who was 5 with us, was wearing my clothes. And my 6 seemed to like her better than me. I wondered if I would be 7 if I weren't there. I told my mom, and she explained that 8 Penelope was a lovely girl, no one could 9 me. I pointed out, 'She is more patient and is neater than I have ever been.' My mom said these were wonderful 10 but I was the only person who could fill my 11 . She made me realize that even with my 12 , -and they were many-I was a loved member of the family who couldn't be replaced. I became a searcher, 13 who I was and what made me unique. My 14 of myself was changing. I wanted a solid base to start from. I started to resist pressure to 15 in ways that I didn't like any more, and I 16 who I really was. I came to feel much more 17 that no one can ever take my place. Each of us holds a unique place in the world. You are 18 no matter what others say or what you may think. So 19 about being replaced.
