【正确答案】 C

【答案解析】[听力原文] Yesterday, a man named Edwin saved two 12-years-old boys in San Francisco Bay. Yesterday afternoon, a group of party guests had gathered at the edge of the picnic area, screaming and pointing at something floating in San Francisco Bay. As Edwin ran to investigate, he soon saw what was wrong: A couple of kids in a rowboat were caught in the current and being pulled out to sea. The two boys, Christian and Jack, who had been at the party earlier, climbed into an eight-foot boat and began rowing out to take back a football. Unfortunately, a beach umbrella caught the wind and pulled the boat into open water. The pair panicked and tried to row back to shore. But they were no match for the elements and spun helplessly in circles. 'We were crying and screaming at each other to keep rowing, ' says Christian. Edwin, 34, a former lifeguard, now an executive at a renewable-energy company, recalls 'Everything went quiet in my head, I was trying to figure out how to swim to the boys in a straight line. ' Then Edwin stripped off his clothes and jumped into the frigid water. After 30 minutes of battling the current, he was about a mile from his starting point and close enough to yell to the boys, 'Take down the umbrella!' Christian wrestled with the tangle. Finally, he uncoiled the knotted cords and freed the umbrella. Then Edwin was able to catch up and climb aboard the boat. 'We're going to get back, ' he told them. Why did the two boys climb into a boat and begin rowing? 短文中提到，为了取回他们的足球，那两个十二岁的男孩爬进了一艘八英尺的船并开始奋力划船，故选C。
