Question

14．Imagine having an idea，drawing it on paper，bringing it to a store and seeing it turned into a physical object．This is now possible with the help of 3D printers．Such machines were once used just by universities and big companies．But now，stores with 3D printing services are appearing around the United States．
    Bryan Jaycox and his wife opened The Build ShopLLC in Los Angeles two years ago．The store is filled with tools like a laser cutter，an industrial sewing machine and 3D printers．Bryan Jaycox requires 15an hour to print an object．He also charge safe depending on the size of the object and up to 50 an hour for design and labor services．
    The Jaycoxs also offer 3D printing classes for anyone who is interested．One of the students in a recent class was Ki Chong Tran．He plans to open a 3D printing business in Cambodia．"The demand has been amazing．It's been much more than I would have imagined，"said Ki Chong Tran．
"I think 3D printing is going to be huge． It's going to make a huge impact on society as a whole，"he added．
    Mr Jaycox predicts that within five years，3D printing technology could become more consumer friendly．
    But Ki Chong Tran says even current technology can make a difference in a developing country like Cambodia．"With 3D printing you can give them tools，and you put it in their hands so they are responsible more for their own development． They learn skills beyond just learning English and becoming a tour guide or something like that or working at a bank．You can actually create things that give value to the world，"said Ki Chong Tran．

点评 1、要想做好科普英语阅读理解题，同学们就要注意平时多读科普知识类文章，学习科普知识，积累常见的科普词汇，从根本上提高科普英语的阅读能力．
2、要熟悉科普类文章的结构特点．科普类文章一般由标题（Head line），导语（Introduction），背景（Back ground），主体（Main body）和结尾（End）五部分构成．标题是文章中心思想高度而又精辟的概括，但根据历年的高考情况来看，这类阅读理解材料一般不给标题，而要同学们选择标题．导语一般位于整篇文章的首段．背景交待一个事实的起因．主体则对导语概括的事实进行详细叙述，这一部分命题往往最多，因此，阅读时，同学们要把这部分作为重点．结尾往往也是中心思想的概括，并与导语相呼应，命题者常在此要设计一道推理判断题．　　
3、在进行推理判断时，同学们一定要以阅读材料所提供的科学事实为依据，同时所得出的结论还应符合基本的科普常识．
