【简答题】
Read the text again and answer the following multiple choice questions. It was a beautiful morning that summer day. I neatly packed everything that I needed into my little green car. Then, I started my car and drove out of my large neighborhood in Lawrenceville. I glanced back at my house for one last time and knew life would never be the same. Arriving at college that day, I realized that I had lost many things. First, I lost my parents' guidance I had had all of my life. The comfort and support of my family would not be there as much as it used to. For instance, when I got sick my mother would make me some hot soup and care for me. Now I have to care for myself without any comfort. Also, I left some of my closest friends. Many of them chose to go to different colleges. It is difficult to keep in touch with friends that are far away. I miss the nights that all of the girls would get together and talk about what was going on in their lives. Finally, I noticed that I missed my hometown. I had lived near big stores and several movie theaters. Here, at college, I feel as if I am in the country. I can’t find any store as big as those in Lawrenceville. Maybe as time goes on I will come to like the move. Now that I have been in college for a few weeks, I am discovering that it is not as bad as I thought it would be. First of all, I have gained new friends from all parts of Georgia and who knows, maybe they will become some of my closest friends. We all go to the same parties and have classes together. Secondly, I have been able to be more independent. For example, in the past, I usually had to have someone by my side wherever I went, but here I feel so comfortable with my surroundings that I sometimes like to take walks by myself. Lastly, I have learned to be more responsible for my actions. I know that homework always comes first and that my social life can wait until all my work is done.
