完形填空

    After seating myself in my room and turning on my computer, I noticed a Post-it note stuck to my monitor(显示器). It read, “Don't turn on your computer. You stayed up until midnight doing your homework last night.—Mom.” I 1the note into the wastebasket. “Why do they 2” I thought. “They're never here anyway.”

    Right after high school started, I almost lost contact with my parents. With all their business 3, they asked the neighbors to watch over me. Of course, the neighbors didn't do such a(n) 4job, as they had kids of their own to worry about. The only means of communication between me and my parents was through Post-it notes.

    After spending about eight hours away from home, I usually came home to find the house 5empty. It made me sad. I would come home from school to be welcomed by6, to talk to no one and to be watched over by my neighbors. That was when I started 7more clubs and staying after school more often so I didn't have to feel so lonely. Luckily, at school, my friends were there for me. They were all there to give me a 8or talk with me when I wanted to talk. I felt great when I was at school. Yet, something was still 9— my parents.

    Now I realize that nobody can take place of my parents. I wish that they would be there at home, waiting for me to come back from school. There are too many things my parents don't know about me. I wish that they actually had a(n) 10to understand me. I want them to understand that they're my parents and I'm their kid and I need them.
