One of them had a permit to work in the area, the other did not, which 17 he could be put behind bars（关押）for staying in this zone. 18 they saw a policeman coming towards them, and 19 . “Run!” whispered the man with the permit to his friend, “I’ll 20 .” They started running and the policeman began chasing them, shouting “stop, stop”.
