      It was a warm April day when a big fat envelope came in the mail from the only college I had ever

imagined attending. I tore open the packet. My eyes were fixed on the word "congratulations."I don't

remember ever smiling so wide.

     Then I looked at my financial (财政的) package.

     The cost of Dream School's tuition (学费), room and board was around $ 40,000- an impossible sum!

How could I afford to attend? What good reasons did I have to go there when three other fine colleges

were offering me free tuition? My other choices were good, solid schools even if they weren't as famous

as my first choice.

     In my mind, attending my dream university would be the only way to realize my dream of becoming a

world-class writer. My parents understood how I felt. They told me that even though it would be a financial

problem, I could go wherever I would be happiest. But as I was always careful with money, I wasn't sure

what to do.

     One of the schools that offered me a full ride had an informational dinner one night in the spring.

to do was smile politely, eat free food, listen quietly. But I surprised myself.

     At dinner the president of the university talked about the wonderful activities on campus (校园) including

guest lectures and social gatherings. He also made it perfectly clear that free food would be offered at all

future events. He continued with explanations of professors, class sizes, activities, and sporting events on

campus. As he spoke, I began to realize that this school, though not as good as my first choice, might be the

best one for me. It seemed small yet with many great programs. It seemed challenging yet caring.

     As the president ended his speech, we clapped politely and pushed back our chairs. As I walked out that

door, a feeling of comfort washed over me. Looking at the campus that night, I realized that I would be

spending the next four years right there.

     In all honesty, my university is not as well-known as my "dream" university. However, it turned out to be

the right choice of schools for me.
