News Report Two

听力原文

A man from Libya was enjoying a walk along the sands at Southport Beach. When he was about half a mile out from the dock, he felt a bit tired. So he lay down and fell asleep, but the tide swept in quickly at the beach. And the man was shocked to wake up and find the tide had come in and completely surrounded him, cutting him off from the shore. (3) Fortunately for him, the beach lifeguards were quickly on the scene to stop him from drowning. They acted professionally to ensure the man was comfortable until an ambulance arrived. He was then taken to hospital. He is now in a stable condition. When interviewed, Keith Porter of the Southport Beach said, “Our beach is so flat that it’s very common for the tide to come around the back of people and cut them off from the beach. (4) Thankfully the emergency services have again worked well together to ensure a positive outcome and we wish the gentleman a speedy recovery.”

4. What did Keith Porter say at an interview?

解析：C。录音最后说道，幸运的是，应急救助服务各方再次通力合作，才确保了结果是好的。C项中efficient对应录音中的worked well together，所以C项正确。其余选项均无原文依据，故排除。
