题目内容：
Sleepless at Night It was a normal summer night. Humidity （湿气） hung in the thick air.I couldn't go to sleep, partly because of mycold and partly because of my expectations for the next day. My mum had said thattomorrow was going to be a surprise.Sweat stuck to my aching body. Finally, Igathered enough strength to sit up. I looked out of my small window into the night.There was a big bright moon hanging in the sky giving off a magic light.
I couldn't stand the pressure anymore, soI did what I always do to make myself feel better. I went to the bathroom and pickedup my toothbrush and toothpaste. I cleaned my teeth as if there was no tomorrow.Backand forth, up and down.Then I walked downstairs to look for some signs of movement,some life. Gladiator,my cat, frightened me as he meowed （喵喵地唱出） his sad song. He was oh the old orange couch （长沙发）, sitting up on his front legs, waiting for something to happen. Helooked at me as if to say, "I'm lonely, pet me. I need a good hug （紧抱）." Even the couch begged me to sit on it.
In one movement I settled down onto the softcouch. This couch represented my parents' marriage, my birth, and hundreds of otherlittle events.As I held Gladiator, my heart started beating heavily. My mind wasflooded with questions: What's life? Am I really alive? Are you listening to me?Every time I moved my hand down Gladiator's body, I had a new thought; each touchsang a different song.
I forgot all about the heat and the next day'ssurprise. The atmosphere was so full of warmth and silence that I sank into itsarms. Falling asleep with the big cat in my arms, I felt all my worries slowly moveaway.The author of the passage could not goto sleep partly because. A．it was too col
