The factory I worked in caught fire last winter. All of us 1 (shock) to find we 2 (trap) in a workshop. The walls 3 (crack) and 4 (brick) fell down frequently. The 5 (electrical) was also cut off. The thick smoke was hard 6 (breathe). It seemed as if we couldn't 7 ( escape ) from the workshop. We were about to give up when a good idea suddenly 8 (strike) me. I told others to wet their coats and covered their heads to protect themselves from heavy smoke and fire. We ran out of the workshop before it lay in 9 (ruin). It was my 10 (wise) that saved our lives.
