English entrance exam for trainee pilots Part One: Read the passage of “Ready for Anything” and answer the questions that follow.
ustin was always prepared. prepared. His motto was "Never throw anything out, you never know when it might come in handy." His bedroom was so full of at bicycle tires, bent tennis rackets, deated basketballs, and games with missing pieces that you could barely get in the door. His parents pleaded with him to clean out his room. "What use is a sh tank with a hole in the bottom" his father asked. !ut ustin simply smiled and repeated his motto, "Never throw anything out, you never know when it might come in handy." When ustin was away from home, he always carried his blue backpack. He liked to think of it as a smaller version of his bedroom#a place to store the many ob$ects that he collected. %t was so worn and stretched that it hardly ha rdly resembled resembled a backpack anymore. %t was full of the kind of things that seemed unimportant, but when used with a little imagination, might come in handy. ustin had earned a reputation for guring things out and getting people out of otherwise hopeless situations. &any of his classmates and neighbors sought him out when they needed help with a problem. 'n the rst day of school, his friend (enny, (enny, came looking for ustin. ")o you think you have something in your bag that could help me remember remember my locker combination" he asked. "% lost the scrap of paper it was written on. % have science class in two minutes and if %*m late on the rst day it*ll make me look bad for the rest of the year." (enny looked genuinely worried. worried. "+ela," ustin said, taking his backpack o- and unipping the top. "+emember "+emember how you borrowed borrowed my notebook in homeroom to write the combination down Well, % know how we can recover recover what you wrote." He took the notebook and a soft s oft lead pencil out of his bag. /he page that (enny had written on had left faint indentations on another page in the notebook. ustin held the pencil on its side and rubbed it lightly over the indentations. 0lowly but surely the numbers of the locker combination appeared in white, set o- by the gray pencil rubbings. 1
"/hat*s amaing1" (enny said. "% owe you one." 2nd he dashed of to to open his locker. )uring science class, &r. /ran was lecturing on the structure of the solar system using a model. He made a sudden gesture and the model fell apart. 3lanets and rings and connector rods went everywhere, rolling and clattering and disappearing under desks. /he students scrambled around on the oor for ten minutes and were nally able to recover every piece ecept ecept one#a connector rod that was lodged in a crack between between two lab stations444. "%f we had a magnet," said &r. /ran, "we could easily coax it out that way. way. !ut % loaned all of the magnet kits to the elementary school yesterday."
