题目内容：

During the last week of my sophomore year（大学二年级）, Mom called me, hoping my summer break would be spent with grandma and grandpa. My grandparents were both in their seventies, and I knew they really needed the help around the farm.

So I packed my car after the final exam and started my life on the farm. As weeks passed, I gradually settled into a routine of daily work with Grandpa. In the evenings I usually read or talked with Grandma.

On the last Saturday in June, I went fishing with my grandfather. Unexpectedly, we saw one of the swans was dead by the pond. Grandpa had given the pair of swans to Grandma on their fiftieth anniversary. "Why don't we buy another one?" I suggested. Grandpa thought for a few moments and finally said, "no... it's not that easy, Bruce. You see, swans mate for life. There's nothing we can do for the one that's left. He has to work it out for himself." A few days later, we drove by the pond and found the other swan lying near the same place we had found the first one. It, too, was dead.

Then July 12 came. Grandma died suddenly that morning of a stroke( 中 风 ). My grandfather was obviously shaken when he heard the news.

The funeral was held the next day. On the second day after the funeral, Grandpa asked  all the people to get back to their own lives. Grandpa was not a man who could outwardly express his grief around others，and we all worried about him．During the rest of the summer, we stayed busy working. I thought there was something different about Grandpa but couldn't tell exactly what it was.

September was nearing, I had to leave. As I drove down the driveway, he waved to me and then walked to the gate to start the morning livestock check. That's how I like to remember him.

Mom called me at school on a windy October day to tell me Grandpa had died. He died of a stroke, the same as Grandma.
