阅读理解 We often hear stories of animals rescuing people. But now someone has aged to return the favour. The event took place one snowy January morning. Thomas Smith was walking his dog, Jack, in the park. "As I was walking, I just saw Jack running onto the ice towards the ducks in the middle, and then he fell into the water and couldn't climb out," said Smith. He realized he had no choice but to try and save his dog. "Someone else told me the lake was only one—metre deep, but it was at least twice that. I had to break my way through the 6-cm ice. Finally, I got Jack by the neck and pulled him out. I don't think I've ever felt so cold by the time we got back to dry land. And when we got there, everyone was asking if Jack was okay—no one was particularly worried about me!" A neighbour, Julie Brown, saw it all happen. "The dog went onto an icy lake. All of a sudden, it started to go under. There were crowds of people around, and they were all shouting and screaming. Before I knew it, the owner (Smith) was in the water forcing his way through the ice. I can't begin to imagine how cold it was, Everyone was very nervous, but he was as cool as a cucumber — he just crawled back out, put the dog on its lead, and went home." Many regard him as a hero, but Mr Smith is quite laid-back about it. "Most dog owners are the same as me. They would do what I did without a second thought. But in the future, I'm going to make sure he's on a lead near any icy ponds.” Pets are members of our family. Would you do the same for them?（1）What happened on a cold January morning?
