亮点原创 For his entire life，USA student Sergio Peralta　　　1　　　playing catch. When he was born，his right hand didn’t fully　　2　　，leaving only tiny fingers at the end of his arm. So he learned to write，eat and carry books with only one hand. Over the years，the 15 - year - old from Hendersonville High School　　3　　hope that anything would change.
Speaking to CBS News，Peralta said on his first day of high school that he honestly felt like hiding his hand in his sleeve（袖子）　　4　　nobody would ever find out. But his classmates　　5　　him in a way he never expected. The school’s engineering teacher，Jeff Wilkins，told him that his fellow students might be able to help.
Three students used online models of prostheses（假肢）and a 3D printer to make a blueprint. They used polylactic acid（聚乳酸），a common　　6　　in 3D printing that’s also used to make electronic devices，as the hand’s main fabric（结构）. They then used　　7　　elastic（有弹性的）plastic material to make the fingers squeeze（捏紧）objects.
Bob Cotter，the school’s principal，told the BBC that his students were　　8　　to turn concepts（概念）into reality（现实），adding that Peralta’s new prosthesis was a testament（证明）to the students who cared about each other.
Peralta，who grew up learning to do　　9　　with his left hand，was even able to catch a baseball using the prosthetic hand created by his classmates. “When I caught it for the first time，everyone started freaking out，” Peralta said with a smile. “It was the first time I had caught a ball with my　　10　　hand in my 15 years of life.”

答案： 1. A 【解析】根据下文可知，Peralta 的右手没有发育好，所以他一直梦想（dreamed about）着玩接球游戏。
2. C 【解析】根据空后的“leaving only tiny fingers at the end of his arm”可知，Peralta 的右手没有发育好，空处应用动词 develop。
3. B
4. C 【解析】根据语境可知，Peralta 试图把手藏起来以便（so that）没人能发现。in order to 意为“为了”，后跟动词原形；because of 和 as a result of 都表示“因为”。
5. D 【解析】根据下文中“his fellow students might be able to help”和“Three students used online models...”可知，同学们用 Peralta 意想不到的方式来支持（supported）他。
6. A
7. B 【解析】句意：然后他们使用另一种有弹性的塑料材料让手指能抓紧东西。因为使用的材料不止一种，所以空处应用 another 表示“另一，又一”。
8. C 【解析】根据语境并结合四个选项可知，学生们被鼓励（encouraged）将概念变为现实。
9. D 10. B
分层设问
1. C
2. D 【解析】根据第四段中“Peralta’s new prosthesis was a testament to the students who cared about each other”可知，Bob Cotter 认为同学们为 Peralta 制作假肢体现了他们之间互相的支持和关心。
3. B 【解析】根据上文内容可知，同学们出于对 Peralta 的关心和支持而为其制作假肢，再结合画线短语所在句中“Peralta said with a smile”可知，当 Peralta 第一次成功用同学们为他设计的假肢接到球时，每个人的心情都应该是激动的。由此可知，画线短语意为“欣喜若狂”，与 B 项意思相近。
