Misha had a two-year-old dog called Gandalf, a search and rescue dog. Misha had trained him for a year with South Carolina Search and Rescue Dog Association.

Misha would train Gandalf whenever she had time. She would give him something like a shoe to smell, then hide it and say to him, "Find, boy!" Hearing this, Gandalf would race off. Soon he would turn up with the very object in his mouth, looking up at her and wagging(摆动)his tail happily. Misha was sure that together, they two would make a brilliant team.

Last Sunday, a 12-year-old boy Michael disappeared from his group's campsite in Doughton Park, 7000 rough acres in the Blue Ridge Mountains in North Carolina. A massive search had been launched, but for 3 days there was barely a track of the boy. The rescue teams were about to lose hope when Misha and Gandalf stepped in.

But this was their first real job. Gandalf would have to pick up the missing boy's smell in the air after three days, a challenging task for even the sharpest animal.

Misha gathered her team of six other members, and they headed north. A sister team had been searching the woods through the night. Misha's team would take over later that rainy morning.

All the searchers found were some dropped potato chips west of Michael's campsite. They'd obtained an unwashed T-shirt from Michael's backpack that hadn't been touched by anyone else and handled it with gloves, carefully cutting it into smaller pieces and sealing(密封) them up in plastic bags.

At 8 a.m. Misha's team were briefed on every detail about Michael. Misha carefully studied his picture to lock his image in her mind. She pulled a bright yellow jacket over Gandalf's head. It had large letters on each side saying "RESCUE", which made Gandalf look like a solider.

Paragraph 1

Then Misha opened a bag containing the pieces of Michael's shirt.

Paragraph 2

The rescue team were about to stop when Gandalf suddenly slowed down nearby a ruined castle (城堡)
