【听力原文】

Last week, doctors operated on a 19-year-old boy, Alex, who was injured in a truck crash. He fractured his spine in two places, and also had a broken arm. During the two-hour operation, the doctors used braces and screws to stabilize the fractures in Alex’s spine. Then they coated the hardware with a newly FDA approved biologic agent called Nanofuse to help grow bone around the braces.
Once Nanofuse is used, new bone soon starts to form. Nanofuse has a high rate of fusion, so patients are able to grow their own bones in a short period of time. Alex was able to take his first step in the hospitals just one day after surgery. Six days after his accident, he returned home.
Questions 25 to 27 are based on the passage you’ve just heard.
