　　(2016·河北省衡水中学高三二模)The last time I saw him was 12 years ago. Twelve years has passed, and I still remember eating pomegranates (石榴) while his thin hands combed through my hair. To this day, I still remember stories my grandfather used to tell me. As a child living in Korea, my grandfather was my closest friend, the man I spent every day with and depended on for back rides. We were inseparable from the moment we awoke until I fell asleep in his arms. I ate the food he prepared, and he was my pillow and storyteller. Little did we know that a day would come when his first granddaughter would leave. My father was to be stationed in the United States and time would blur (使……变模糊) our images of each other.

　　On the summer of my sixteenth birthday, I would see my grandfather again. On the plane, thoughts of him ran through my mind during all 14 hours of the flight. Would he look the same? Would he be healthy? Did he still have the pictures I drew for him? Most importantly, would he remember me? I was short then and always smiling. He dressed me. Twelve years later, I was taller and had a different figure. I picked out my own outfits and had my own sense of style. I was scared he wouldn't recognize I was his granddaughter.
