| The night started out ordinarily enough. Jack and Tara, our 1 , were in their small beds surrounded by toy animals. My husband, Pat, and I went to sleep 2 . 3 after midnight, Jack quietly touched me. "Mommy, I want to stay with you. I promise I won't take much room." I shifted 4 to make room. My son soon fell asleep. An hour later, Tara cried and I carefully went downstairs. "Mommy, my 5 is an stuffed up (堵住). I can't really breathe very well. Will you please 6 with me a little while?" Tara doesn't often get up at night. 7 . I decided to be there for her. She soon fell asleep. I returned to my own bed. I was determined to sleep. But to my 8 , I found Jack sleeping on my side of the bed. He looked so 9 that I couldn't remove him. Quietly and carefully, I lay down between 10 and Jack. I did manage to get some sleep 11 I heard Tara's voice again. I returned to 12 Tara. "Mom, please lie down with me a little bit. I had a bad dream, and I'm so 13 ." "Of course, honey. It was only a dream Mommy's here and 14 is okay." We fell asleep 15 each other's arms. Even in my sleepy state, I thought of 16 these nights of merry-go-round (一连串的繁忙活动) beds will be over. In their place, my twins will be grown 17 before I'm ready, our children' rooms will be much too 18 and empty. So it is especially on days when I'm worn out after a night on this mom's merry-go-round that I remind 19 that these very days and nights are, in fact, "the good old days", ever so 20 . | ||||
