I know a Catherine who is smart, educated and interesting. But I avoid her because she never 1 complaining( 抱怨 ) ! For years, I fought against my feelings, because I really like and admire her, but I ’ ve found I just can ’ t be her friend. Her world is 2 “ buts ...” . The trip would have been nice, but the drive was too long. The food was good, but the light of the restaurant was too 3 . The hotel was too hot, the bed hurt her back and the room service was too slow. Her complaints were 4 changing me. Months ago, my best friend Daisy was listening to me complaining about Catherine 5 she just became really angry. “ Either break up with her, or leave me alone. ” She shouted at me, “ I ’ m tired of listening to your complaining. ” Her honesty surprised me, and I began to keep myself away from Catherine. Later, I d id 6 her. Now I try to remain happy and positive ( 积 极 的 ) about life, and find friends of the same. There ’ s been scientific research lately. It shows that people who find 7 to be thankful for their lives are actually happier, and I believe that is true. Endless complaining seems to control your life if you let it come into your brain. And too much complaining will actually make your life 8 . Some people take “ gratitude ( 感激之情 ) walks ” every day, where they 9 their lives in a positive way. By developing a grateful attitude, you can be turned away from what ’ s troubling you, and 10 what makes you happy. Then you will have a beautiful life.
