题目内容：

    On September 11, 2001, I was in the second week of the new school year with my senior English class at T. C. Williams High School just a few miles south of the Pentagon.

Suddenly that morning, a colleague who grew up in New York, opened the classroom door and said, "Turn on the TV the World Trade Center has just been hit by a plane. " I've always believed in never letting school get in the way of my students' education. I switched on the TV in front of the room, and my students and I listened to the announcers make a guess about what had happened——only to see the second plane hit. At first, the sight of the towers burning didn't seem to have much more immediacy (紧迫性)than a TV action movie. Soon, however, things in that classroom would get far too immediate.

In what seemed like about a half-hour after the second plane hit, we heard a loud explosion outside the school. Several students were shocked and I told them not to worry, saying that "it was just a car backfiring". A moment later a boy sitting near the windows said, "That's no car； look at that black smoke." We could see an enormous plume of smoke rising in the distance, but didn't know where it was coming from until, a few seconds later, the NBC reporter stationed at the Pentagon broke into the New York coverage to say that he felt the ground shake beneath him as he heard an explosion—obviously the same one that had just surprised my students. It was several minutes before it was announced that the explosion came from a plane hitting the Pentagon.

At that point, a boy a football player suddenly came undone and had to be comforted by the girls in the class. His mom worked in the Pentagon, and when he tried to get her on his cellphone he could not get through.

Reports vastly overestimated the number of deaths in the Pentagon. Some reports were estimating over 800 dead when the actual death toll at the Pentagon was 125.
