A Leap(跳跃)to Honor Leaping on a narrow balance beam(平衡木) is not easy. But Lola Walter, a 13-year-old gymnast, is an expert at it. To perfect her skills, Lola 36 for four hours a day, five days a week. At the state championships in March, she finished seventh out of 16 girls. That’s especially impressive, 37 she is legally blind, born with a rare condition that causes her eyes to shift constantly. She often sees double and can’t _38 how far away things are. When she was little, her mom 39 that even though she couldn’t see 40 , she was fearless. So her mom signed her up for gymnastics when she was three. She loved the 41 right away and gymnastics became her favorite. Though learning gymnastics has been more 42 for her than for some of her tournaments, she has never quit. She doesn’t let her _43 stop her from doing anything that she wants to. She likes the determination it takes to do the sport. Her biggest 44_ is the balance beam. Because she has double vision, she often sees two beams. She must use her sense of touch to help her during her routine. Sometimes she even closes her eyes. “You have to 45_ your mind that it’ll take you where you want to go,” says Lola. To be a top-level gymnast, one must be brave. The beam is probably the most 46 for anyone because it’s four inches wide. At the state competition, Lola didn’t fall 47 the beam. In fact, she got an 8.1 out of 10---- her highest score yet. Lola doesn’t want to be 48 differently from the other girls on her team. At the competitions, the judges don’t know about her vision _49 _ . She doesn’t tell them, because she doesn’t think they need to know. Her mom is amazed by her _50 attitude. Lola never thinks about 51__ . She is presently at level 7 while the highest is level 10 in gymnastics. Her 52 is to reach level 9. She says she wants to be a gymnastics coach to pass down what she’s learned to other kids 53 she grew up. Lola is 54 of all her hard work and success. She says it’s helped her overcome problems in her life outside gymnastics, too. Her 55 for others is “just believe yourself”. 小题1: A.runs B.teaches C.trains D.dances 小题2: A.since B.unless C.after D.though 小题3: A.tell B.guess C.assume D.predict 小题4: A.suspected B.remembered C.imagined D.noticed 小题5: A.deeply B.well C.ahead D.closely 小题6: A.task B.sport C.event D.show 小题7: A.boring B.enjoyable C.difficult D.unsatisfactory 小题8: A.talent B.quality C.nature D.condition 小题9: A.doubt B.advantage C.challenge D.program 小题10: A.examine B.express C.open D.trust 小题11: A.fearful B.harmful C.unfair D.inconvenient 小题12: A.to B.on C.off D.against 小题13: A.greeted B.treated C.served D.paid 小题14: A.pains B.stresses C.injuries D.problems 小题15: A.positive B.friendly C.flexible D.caution 小题16: A.defending B.quitting C.winning D.bargaining 小题17: A.standard B.range C.view D.goal 小题18: A.until B.as C.when D.before 小题19: A.proud B.tired C.ashamed D.confident 小题20: A.plan B.advice C.reward D.Responsibility
