     When I moved into an empty dorm (宿舍) for the first time two years ago, I was certain of a few
things. Firstly, I realized that I didn't   1   anybody at the school. Secondly, I knew that l wanted to work
hard at my lessons and   2   something useful. And thirdly, I wanted to have a good time with new
classmates, without my parents around.
     The first   3   frightened me in the beginning. But that    4  quickly disappeared. It was the other two
goals     5  ended up being my difficulties. I knew that it was   6    to devote enough time to class and to
social efforts. But I wanted to   7   in both. I knew this would be a    8   , but I didn't realize how much
until classes began. 
     I got on well with the other girls who lived in my dorm.    9    , instead of finishing my homework 
   10  it was due, I went upstairs and had ice cream with my neighbor. I always finished it the next day
between classes. I knew   11   wasn't very good and the grade I   12   showed my lack of effort.
     I was   13   that I needed to find some sort of balance.
     So I created a schedule (时间表) that would   14  my time up between going to class, doing
homework, and relaxing. It seemed like a good idea,   15  I was only able to   16  it for a few days. A
schedule like that was too much pressure.
     So I tried another    17  . Each week I made a list of everything I had to get done during that week.
Then, under the list of things I had to get done, I   18   a list of things I could do if I had time.
     This is the method I have used since then. I'm glad that I've learned to    19  things and it has    20  
prepare me for what is to come after graduation.
