B

    Last summer, Mac Hollan, a primary school teacher, was cycling to Alaska with two friends. On the way, his friends had to stop for a bicycle repair, but they encouraged Mac to ride on, and they would catch up with him soon.

    Mac began to cycle alone. A few minutes later, Mac heard quick and loud breathing behind him. "Man, that's a big dog!" he thought. But when he looked to the side, he saw immediately that it wasn't a dog at all, but a wolf, quickly catching up with him.

    Mac's heart jumped. He searched and took out his can of bear spray(防熊喷雾). With one hand on the bars, he fired the spray at the wolf. A bright red cloud enveloped the animal. To Mac's relief(宽慰), it fell back, shaking its head. A minute later, however, it was again by his side. It even attacked the back of Mac's bike, tearing open his tent bag. He fired at the wolf a second time, and again, it fell back, only to quickly restart the chase(追赶).

    Mac was riding hard now. He waved and shouted at passing cars without slowing down.

    At that moment, Paul and Becky were driving their car on their way to Alaska. They found a dog-like animal running alongside a man on a bike. As they got closer, they realized that the "dog" was a wolf. Mac heard a large car behind him. He kept waving and shouting as the wolf was catching up closer. And the car did stop in front of him at the right time.
