The other day, I happened to meet someone I hadn’t seen for many years. I couldn’t believe the change in him. In fact, he didn’t even seem like the    36   person.

When I first knew Bill , back in   37 , he was one of the most carefree（无忧无虑）people I had ever    38  . He was always ready to have a party. He thought    39  of going out for beer at three o’clock in the morning or driving 15 miles to see an old   40   he really liked. Bill and I were in the same class in college, and    41   was never dull when he was    42  . With him there was one wild    43   after another. Sometimes I wonder how we    44   to study for our exams.

Last week I was in Houston on business and I ran into Bill in the bar at the hotel.   45  , I wasn’t even sure it was    46  . Was this short-haired businessman really the same person? I wasn’t really sure until I came near him but it indeed was Bill. Now he works for a bank. He   47    most of the evening about his job, his new car and his house. How he had changed! Back when we were in college, the    48   thing Bill cared about were possessions(财富). Now they seemed to be his main    49  . Although I have changed quite a bit myself, somehow I never    50   Bill changing so much. My image of him   51    the one I had formed     52  the time when we were college students together.

I suppose it’s   53    to expect people to remain the same, especially    54   I have changed so much myself. But I must say that I enjoyed the old Bill much more than the new Bill. Maybe he    55   the same way about me.
