Meeting a polar bear

I put my day's supply of food into my bag and then began to take down the tent. Suddenly I heard a deep, long growl (嚎叫) from my dog Charlie. I looked at him and then in the direction he was watching closely. A polar bear!

It was a mother 1 by two cubs coming slowly towards me. They were 200 meters away. With a pounding (狂跳) heart, I picked up my flare (照明) gun and 2 walked sideways a few steps to Charlie. Without taking my eyes off the bear, I untied Charlie and, again walked sideways.

The bear, now only 150 meters aways, wasn't stopping. Her cubs had dropped back but she kept going, while I tried to remember all the 3 that had been given. Keep eye contact, move sideways or forward, never backward, stay calm, don't show 4 . Don't wound a bear and you'll make it 5 to control it. Never run. Repeating to myself, "Stay calm, stay calm," I fired a warning shot (射击) to the bear's left. The loud noise had no 6 . She came around. I fired a flare, landing it a little to her right. Her head moved in its direction but she didn't stop. I fired another, this time dropping it right in front of her. She stopped, looked at the flare. She was only 30 meters away now.

By this time, I was so nervous that my heart could have been heard at base camp. The bear began to step around the flare, and I dropped another a meter in front of her. again she 7 , and then she fixed her tiny black eyes on Charlie, who was trying to reach her. She looked back at her cubs, waited, and then moved to my left in a half circle. I fired two more flares, trying to draw a line between her and me. She stopped again and seemed to want to 8 the line of flares but was unsure of the result and of Charlie, so she decided to stay 9 . Finally, with a last long look, she walked north with her cubs behind her.

My hands were still shaking, but I now knew that I could 10 a bear in the wild bravely and stay calm enough to act properly.
