题型:填空题

     It was a normal Saturday morning, and everyone was in a good mood. The year was 2000 and I was

then only 6 years old. I remember it like it was yesterday though. We were just eating breakfast when we

received a phone call. We received phone calls all the time, so it was nothing new to me. However, this

phone call was an important one. I soon heard and saw my mother crying on the couch(沙发)with my

father comforting her. My brother, sister, and I didn't know what had happened, as they had not told us

yet. Later, I was told that my grandfather was in the hospital because he had a heart attack. I did not know what to think. I had never heard of a heart attack, but I figured (认为) that it must be serious if he was in

the hospital.

     My grandfather and grandmother lived far away from us and we did not get to see them often. It was a long trip. My mother rushed to the hospital while my father stayed at home with my brother, sister and me.

     I do not think my young sister was really understanding it all yet. My mother returned a little later with

bad news. My grandfather had died before she got there. I was speechless. I had loved my grandfather

greatly. He was the one who taught me how to fish and enjoy the outdoors.
