Lehrner always wanted to design roller coasters (过山车). Even as a(n)  41  , though, she knew that there had to be more to it than just hopping on board. “I started   42   how I would prepare,” she says. She looked to science and math and took classes in algebra (代数)and geometry(几何学) in middle school and high school. Then she did even more advanced math and a high-level physics course.
She also   43   theme parks as often as she could and researched the teams making those coasters online. When it came time for   44  , she went to the Colorado School of Mines in Golden, where she   45   a bachelor’s degree in mechanical engineering.
Now Lehrner works with amusement parks to design and   46   new coasters. These new coasters they design are   47   made of wood, except for a metal   48   on which the cars run. The basic design has been around for more than a century. Still, Lehrner notes each new one is different. “ A lot of the same components and concepts are used when I design new coasters. But they   49   with the terrain (地势) and design. That tells us what the limits will be— how tight the bends and how   50   the hills are.”
Some parks   51   their coasters to be as scary as possible. That means big   52   and quick turns and lots of inversions (倒转). Lehrner is expert at making twisted wood coasters. The coasters she   53   make you feel as if  you’re going   54   than you really are, because the tracks are lower to the ground. “We also try to build rides that are fun for the whole   55  — children as well as their parents,” she said.
