Question

7．Leon McCarthy，12，was born w ithout fingers on his left hand．That didn't stop him from being able to do many tasks．But Leon could not grasp more than one object at a time．So Leon's father，Paul，created a Prosthesis（假肢），using a 3D printer．Now Leon has fingers that open and close．"It was a do-it-yourself，father-and-son adventure．"says Paul．
When Leon was a baby，his doctor advised his parents not to give him a prosthetic hand until he was in his early teens．"The doctor said Leon should first lea rn to get full use out of the hand he was born with，"says Paul．As Leon got older，his father looked into buying a prosthetic hand，which can cost as much as  30，000．Paul found a more affordable solution．
One day，Paul discovered a video on the Internet about Robohand，a prosthesis created with a 3D printer．He downloaded the free instructions and called Robohand's creators for advice．They told him all he needed was a 3D printer--which costs around  2，000--and some materials．
Luckily，Leon's school had recently purchased a 3D printer and it offered to help Paul build the hand for Leon．"We used a soccer shinguard（護(hù)脛），cardboard，and tape．They cost about  10．"says paul．
With his new hand，Leon can do things better．"I can help my mom more，because now I can carry two grocery bags，"he says．
Leon's father has already built several hands for Leon．Leon helps design each one．He says there's one thing in particular that he wants to do with a future prosthesis．"The goal，"he says，"is to be able to tie my shoelaces（鞋帶）．"

Answer 1

分析 本文主要寫了Jayson天生左手沒(méi)有手指頭，為了幫助孩子他爸爸用3D打印機(jī)為孩子建了假肢．

解答 21．A 細(xì)節(jié)理解題．根據(jù)醫(yī)生的話The doctor said Jayson should first learn to get full use out of the hand he was born with．Jayson應(yīng)該先學(xué)會(huì)充分利用他天生的手，所以答案選A．
22．C  細(xì)節(jié)理解題．根據(jù)句子Jayson's school had recently purchased a 3D printer and it offered to help Paul build the hand for Jayson，Jayson的學(xué)校擁有3D打印機(jī)，它幫助Jayson的爸爸Paul為Jayson建了一個(gè)假手，所以答案選C．
23．D 細(xì)節(jié)題．根據(jù)文章內(nèi)容his father looked into buying a prosthetic hand，which can cost as much as 30，000．Paul found a more affordable solution…They told him all he needed was a 3D printer-which costs around 2，000-and some materials．買假肢要花費(fèi)3000多，而3D打印機(jī)只需要2000多，相比較而言，3D打印的手是經(jīng)濟(jì)又實(shí)惠的，故選D
24．C 主旨大意題．本文主要寫了Jayson天生左手沒(méi)有手指頭，為了幫助孩子他爸爸用3D打印機(jī)為孩子建了假肢．所以答案選C．
