听力原文

    (5) A pilot from Virginia removed his son’s loose tooth using a helicopter. Rick Rahim, from Virginia, flies helicopters for a living, and when his seven-year-old son’s tooth became loose he did not waste time by tying it to a door handle. Instead, Mr. Rahim tied one end of a string around his son’s tooth, and the other end to his full-sized commercial helicopter. (7) The father of four posted a video clip of his playful venture on Facebook, advising parents to do fun and creative stuff with their kids. The video shows him launching the helicopter into the air and flying just far enough to successfully remove the loose tooth. (6) At the end of the video, Mr. Rahim assures watchers that the circumstances were safe, and that he has 13 years of helicopter flying experience behind him. “You’ve got to do everything safe in life, and that’s what I did today,” he said. Mr. Rahim later said that although some parents have used remote control helicopters to pull teeth before, he might be the first to use a full-sized aircraft, as he can’t find evidence that it has been done before.

5. How did Rick Rahim remove his son’s loose tooth?

解析：D。根据录音开头可知，来自弗吉尼亚的里克·拉希姆用一架直升飞机拔去了他儿子松动的牙齿。A项与录音意思相反（did not waste time by …）。B选项未提及。C项是录音中其他父母做过的事。里克·拉希姆所做的是第一次使用一架全尺寸的直升机，所以D项正确。
