　　Jean's father was a farm plane pilot in the little farming community in Northern California where she was raised, and 　　1　　Jean was totally attracted by airplanes and flying．

　　In her senior year of high school, her English teacher was Mrs．Dorothy Slaton．Mrs．Slaton was a 　　2　　, demanding teacher with high standards and a low 　　3　　 for excuses．She refused to treat her students like 　　4　　, instead expecting them to behave like the 　　5　　 adults they would have to be to succeed in the real world after graduation．Jean was 　　6　　 of her at first but grew to respect her firmness and fairness gradually．

　　One day Mrs．Slaton gave the class a written 　　7　　．"What do you think you'll be doing 10 years from now?” Jean's dream was to be a pilot like her father, but as the years went by, she had been beaten down by the 　　8　　 and negative words she got whenever she talked about her career, so she unwillingly gave it up and wrote something else．Mrs．Slaton collected the papers and nothing more was said．Two weeks later, the teacher handed back the assignments, 　　9　　 the students to face it down on the desk, and asked this question："If you had enough finances and unlimited 　　10　　, what would you do? Please write it on the 　　11　　 of your previous assignment paper．”

　　When the students stopped writing, the teacher asked, "How many of you wrote the same thing on 　　12　　 sides of the paper?" Not one hand went up．

　　The next thing that Mrs．Slaton said changed the course of Jean's life．The teacher leaned forward 　　13　　 her desk and said, "I have a little secret for you all．You do have 　　14　　 abilities and talents．You do have access to the finest schools, and you can arrange plenty of finances if you want something 　　15　　 enough．This is it! When you leave school, 　　16　　 you don't go for your dreams, no one will do it for you．You can have 　　17　　 you want if you want it enough．”

　　What her teacher said touched Jean so much! In the following years, she tried her best to realize her dream of becoming a pilot．Although it didn't happen 　　18　　, she finally became one of the first three female pilot trainees ever 　　19　　 by United Airlines．Today, Jean Harper is a Boeing 737 captain．

　　It was the power of one well-placed 　　20　　 word that gave that uncertain young girl the strength and faith to pursue her dream．
