A big fire broke out in a clothing factory in our city last Wednesday. At 9:18 that morning, when the employees were working       (busy) in the 4-storeyed building, heavy smoke was seen      (come) out of the windows on the second floor. The fire lasted nearly an hour, and the majority of the 345 employees managed     (escape) from the fire. Unfortunately, 7were killed, and 23 injured, lightly or seriously.
Some workers     (complain) that aids came too late,      the firemen did come just 10 minutes after the fire was reported. To rescue everyone from the burning and smoking building in such a short time was too difficult. The only two exits of the big building were not enough for so many people to withdraw in    hurry.
The reason of the fire, according to an investigator, was     someone broke the non-smoking rule in the factory, because some cigarette    (end) were found. Next two weeks, 15 inspection teams will be working in all the factories     turn, aiming to clear away the possibility of more fires.      (hope), no disasters like this will happen again.
