It's unbelievable to save this black bear from falling off a 30-meter-high bridge.
The bear was (A) ____ her way home after a long day in a California's mountain. She was walking across the bridge when, suddenly, two cars entered from both sides. There was nowhere to run, so the frightened bear jumped onto the rail (护栏) and began to fall down.
Luckily, the bear pulled herself onto an arch under the bridge, but she couldn't get out. A driver saw the surprising scene and called for help. Robert Brooks, an animal control officer from a nearby arch n. 桥town, was sent to find out the truth. "I thought it was a joke." he said. But it wasn't a joke, so he called Dave Baker of the BEAR League, a group that helps bears in (B) ____.
(C) Unfortunately, the sky was getting dark, so the workers who saved the bear had to wait. Early the next morning, Brooks and Baker returned to the bridge with more volunteers. To their surprise, the bear was still there. Then Baker had an idea. ①They should hang a net under the bear, push her into (D) it and then lower her to the ground.
Police officers closed the road. ②When the bear was sleepy, a volunteer rock climber used his feet to push the bear off the arch, right into the middle of the net.
③When the bear was gently lowered to the ground, everyone cheered. The police officers then cleared all the people from the area and left the bear alone when she slept. Since then, no one has seen the bear. "I don't think she's going near the bridge any more." Brooks said.
