On September 11, 2001, Omar Eduardo Rivera,
a blind computer technician (技术员), was working on the
71st floor of the World Trade Center with his guide dog {#blank#}1{#/blank#} (name) Dorado.
When the hijacked (被劫持的) plane hit the tower, Rivera
knew {#blank#}2{#/blank#} would take him a long time to escape from the building, but he
wanted his lovely dog to have a chance {#blank#}3{#/blank#} (get) out so he set him free in
the crowded stairwell. "I thought I was lost forever—the noise and the
heat were {#blank#}4{#/blank#} (terrify) —but I had to give him the chance of escape. So I
touched his head, gave him a push and ordered him to go," Rivera said.
The dog {#blank#}5{#/blank#} (immediate) disappeared
into the crowd, but a few {#blank#}6{#/blank#} (minute) later Rivera felt the dog feeling
his legs. Dorado came right back to his side and a co-worker
{#blank#}7{#/blank#} (bring) by him as well. Then Dorado and the selfless co-worker
{#blank#}8{#/blank#} (help) Rivera climb down 70 flights of stairs, {#blank#}9{#/blank#} took nearly an
hour. No sooner had they escaped from the building {#blank#}10{#/blank#} it fell down
completely, and Rivera says he owes his life to his faithful dog.
