More recently, most Americans remember what they were doing when the World Trade Center in New York was taken down by terrorists. It is one of the {#blank#}1{#/blank#} events in American history. Even the date—September 11, 2001—has {#blank#}2{#/blank#} to most Americans.

    This was a day Peter Hunt will never forget. In May 2001, he {#blank#}3{#/blank#} a job in the World Trade Center. On September 11, 2001, he arrived at his building at around 8:30 a.m. He was about to go up when he decided to get a coffee first. He went to his favorite coffee place even though it was two {#blank#}4{#/blank#} east from his office. As he was waiting in line with other office {#blank#}5{#/blank#}, he heard a loud sound. Before he could join the other people outside to see what was going on, the first plane had already hit his office building. They stared in {#blank#}6{#/blank#} at the black smoke rising above the burning building. He felt lucky to be alive.

    Kate Smith will never forget the date, too. Now she still {#blank#}7{#/blank#} working in her office near the two towers. "My friend Mike shouted {#blank#}8{#/blank#} that a plane just hit the World Trade Center! I didn't believe {#blank#}9{#/blank#} at first. But then I looked out of the window and realized that it was {#blank#}10{#/blank#}. I was scared and I could hardly think clearly after that."

    September 11, 2001—the date alone means something to most people in the US.
