SAT语法大全(附答案)

　　The Rocket Scientist behind the Super Soaker

　　It is not generally advisable to spout a stream of water across a boardroom filled with executives. However, Lonnie

　　Johnson—NASA engineer, inventor, and creator of the Super Soaker—delighted the president of toy company

　　Larami Corp. with this very display. In 1989, after a seven-year trudge through failed patents and rejections, Johnson

　　finally got his Super Soaker to store 1 shelves where it reigned as the most popular water gun toy of the 1990s. His

　　product and 2 it’s spinoffs still predominate that market today. A combination of luck and perseverance contributed to

　　Johnson’s successful creation.

　　[1] The discovery that 3 ended up eventually leadingJohnson to his first Super Soaker model was

　　serendipitous.[2] At the time, Johnson’s day job was at NASA’s Jet Propulsion Laboratory, where he helped design

　　an atomic battery for Galileo, a spacecraft created to observe Jupiter.[3] By night, Johnson explored his own

　　inventions in his home office. [4] Johnson’s prototype sported a long plastic tube and a metal spigot. [5] He aimed it

　　at the bathtub, and the powerful torrent of water it yielded put him 4 at mind of a high-powered water gun. [6] The

　　next step—an arduous one—was to find a company with the desire and means to produce it. [7] 5 After expressing

　　initial interest, Johnson was dismayed when one toy company ended negotiations. [8] The next company he

　　approached went bankrupt. [9] He persisted and, after Johnson’s interactive display in that boardroom, Larami Corp.

　　bought the Super Soaker and created fourteen different models of water guns based on his design. [10] A decade

　　later, over 200 million Super Soakers had sold, generating over $400 million in revenue. 6

　　7 Johnson’s physics and engineering skills were critical to his toy design. Traditional water guns are held in one hand

　　and require just a trigger pull to eject the water from a small cavity. Johnson’s invention, 8 by contrast,calls for more

　　muscle, requiring two hands to operate an air pump before discharging, and stores water in a larger container. The

　　pump action on the Super Soaker allows the user to compress the water and store more energy, resulting in a mighty

　　cascade of water.

　　While he enjoyed the accomplishment of creating this product, Johnson also sought to solve problems more complex

　　than 9 amending summer fun. He embarked on his own 10 business. He founded Johnson Research and

　　Development with his Super Soaker proceeds. He owns over 80 patents, and his main goal is to create more viable

　　options for renewable energy. Johnson’s 11 persistence knowledge and a happy accident paved the way for his

　　success as an independent inventor.
