Twelve people in a tunnel - level 2
An accident happened in northeast China. A railway tunnel was under construction when it collapsed. The reason for the collapse is not known. The tunnel trapped twelve workers. People rescued them after 63 long hours. All of the workers were conscious but they were carried out. Some of them could even walk. They were taken to hospital. The ambulances waited outside. Difficult words: to trap (to keep something in one place), rescue (save), conscious (awake and active).
