　　“Everything happens for the best, ” my grandmother said whenever things weren't going my way．“Don't worry, one day your luck 　　1　　(change)．”

　　Grandmother was right, as I discovered after graduating from college．I had decided to be sports announcer(广播员)in a radio station, so I 　　2　　(go)to Shanghai and knocked on the door of every station．But I got refused every time．

　　In one station, a kind lady said my problem was short of experience．“ Get some work with a small station and 　　3　　(work)your way up, ” she said．

　　I couldn't get a job there, either．Then my dad told me a businessman had opened a company and needed someone 　　4　　(manage)the sports center．But again, I didn't get the job．

　　I felt really down．“Your luck will change, ” Granny reminded me．I tried another radio station in Beijing．But the owner, a nice man, told me he already had someone．

　　As I left his office, I asked, “ How can someone be a sports announcer if he 　　5　　(not, get)a job in a radio station? ”

　　I 　　6　　(wait)for the elevator when I heard the man call, “What was that you said about sports? Do you know anything about football? ” I 　　7　　(put)in front of a microphone and asked to imagine I was commenting(评论)on a football game．“Now you 　　8　　(watch)the football game between Lu Neng and Shen Hua…”

　　On my way home, Granny's words came back to me, “One day your luck will change, boy．And when it 　　9　　(happen), it'll feel twice as good because of all the disappointment(失望)you 　　10　　(have)．” At that moment I knew just what she meant．
