A few weeks ago, our dog, which we had kept for more than ten years, had to be put down. First, a tumor on her stomach got worse, and she was very 36 . Then, the pain in her back got so bad that sometimes she 37 lie down in the middle of a walk and couldn't take another 38 . When I first found out, l was very sad and cried a lot. She was more like a sister to me than a 39 .But I was also angry at my stepfather,Steve,who told us the 40  a week after it happened. He   41 because he didn' t want to worry us, and he didn't want me to get depressed(抑郁的) and fail my exams. I just thought she was 42 at the animals' hospital. I think you know all the 43 that went through my head: She was my dog！Why didn't he tell us earlier? I didn't even get to say goodbye. People in my family have a 44 of keeping things from me to protect me, such as only telling me that my aunt had cancer 45 she had already improved health. All I could think was: Not again ! I 46 to my mum, and she said， “I know. I'm 47 , too.” I opened my mouth to shout. And then she added, “I'm so angry with Steve that he had to 48 through all this on his own.”Hearing my mum's words, I shut up my mouth. I had been so 49 on myself. I hadn't thought about 50 Steve was going through. That dog was his baby. He'd had her for longer than he'd had us—and he had to make the decision to 51 her life, and then kept in silence for an entire 52 . All my anger melted away, and all I felt was 53 . It makes me realize that we focus so much on ourselves that we 54 the pain of others. At that moment, my mum's words were an incredible 55 that I'll never forget. 小题1: A．lazy B．lonely C．painful D．shameful 小题2: A．would B．should C．might D．could 小题3: A．walk B．step C．foot D．breath 小题4: A．tool B．toy C．baby D．pet 小题5: A．plan B．accident C．anecdote D．truth 小题6: A．lied B．waited C．reflected D．hesitated 小题7: A．still B．once C．even D．never 小题8: A．facts B．opinions C．thoughts D．doubts 小题9: A．story B．secret C．habit D．hobby 小题10: A．until B．before C．while D．after 小题11: A．adjusted B．turned C．contributed D．related 小题12: A．angry B．shocked C．guilty D．abused 小题13: A．break B．go C．look D．push 小题14: A．focused B．hooked C．dependent D．hard 小题15: A．that B．where C．what D．which 小题16: A．save B．expand C．make D．end 小题17: A．year B．month C．week D．day 小题18: A．regret B．blame C．sorrow D．sympathy 小题19: A．shared B．ignored C．reminded D．rid 小题20: A．comfort B．compromise C．gift D．suggestion
