阅读理解。 After their 15-year-old dog Bailey died in 2007, Ron and his wife, Ann, looked for months to find the right new pet. "I love dogs," says Ron, a worker at a health club in Waukesha, Wisconsin. "I can't imagine not having one." Finally, the couple spotted a young dog at the Humane Society in Milwaukee. His name was Oscar. "He was very attractive," says Ron, 65. Oscar quickly made himself at home, sleeping on his new owners' bed at night. A diabetic(糖尿病人) for 25 years, Ron faithfully took his medicine four times a day and generally had no problems. But on March 17, at about 3 a.m., he got out of bed to use the bathroom. Suddenly, he fell down to the floor. "I must have taken the wrong amount of medicine before I went to sleep, because my blood sugar was erously low," he says. "Normally, Oscar is very quiet and well-behaved," says Ron. "But when I hit the floor, he let out sounds like a wild animal." "Honestly, it sounded like the dog from hell," says Ann, who was awakened by the sound." I didn't know what the sound was. Then I saw my husband lying on the bathroom floor. He was cold." She ran for the phone and called an ambulance. Ron spent several hours in the hospital. By 6:30a.m., he was well enough to go home. "You would never suspect Oscar of any heroism." says his grateful owner. "He's a wonderful little guy. We are lucky enough to own him." Even before Oscar's heroic action, the couple had given their pet a new nickname(昵称). "We felt the name Oscar wasn't good enough," says Ron, "so sometimes we call him Eduardo"-more suitable, they think, for their dog. 1. What was Ann doing when Ron went to the bathroom? A.
