Dear Captain Lim,
I used to be afraid of flying, but after reading your book, I felt much    (good)every time before I flew.    (read) your book helped me to build up my courage (勇气) to fly. However, I have had this scary    (feel)again since the MH370 incident (事件). Last week, I also read a pieceof news that a plane went through severe turbulence (强烈的气流). Most passengers on it were      (scare) and several of     even got hurt. May I know whether this kind of severe turbulence often happens and have you    experienced this kind of situation before? How do pilots usually take     of it? For passengers, it seems that it’s not    to control(控制). But do pilots feel the same or is everything actually controlled by pilots when there’s severe turbulence? I really hope you can answer these
  (question). Captain Lim, please help me as I am so afraid     sometimes I can’t sleep after thinking so much about flying.
Thank you very much.
Marissa
