【听力原文】
Hi, my name is Aida. I am a PA, physician assistant. I’m 38 years old. My journey to being a PA happened in my thirties. After having gone through a career of coaching in a volleyball team, I reinvented myself, because it didn’t quite get my daughter and me in a comfortable situation. Because my family has a lot of medical background, I got interested in the medical field.
And not wanting to go through eight plus years of school, I started exploring different routes. Physical therapy was also an option that I did consider. But I looked more into the PA route because I was really interested in it. So, I started to do prerequisites that I needed. Although I already had a master’s degree, I still needed some learning in subjects like organic chemistry and anatomies and stuff that I didn’t have. It was probably about a four-year journey before I was finally a PA.
Questions 16 to 18 are based on the passage you’ve just heard.
