Question

7．    If your pen broke at school today，what would you do？You would go to a shop and buy a new one．What if you could simply print out a real，working pen with your 3-D printer without leaving your room？
  Ten years ago people could only see 3-D printing in science fiction movies．But now 3-D printing is here and it's bringing big changes．
  Unlike normal printing that can only copy a 2-D picture with ink.3-Dprinting can build almost anything made from material．The printer layers（分層） the material in different shapes to create the object you want to be copied．
  The 3-D printer has been used to make many different things．People have made cups cars and even an airplane with it．
  Doctors have been using 3-D printers for several years．People's nervous systems have been printed out in 3-D form medical research．Some body parts have been printed and used in hospital．Several months ago，doctors used a 3-D printer to rebuild the face of a person who had a bad accident．In the future，it is expected that the printer will make human organs to save more lives．
  However there are drawbacks to the printer．At the moment，printing can be quite slow and it's still rather expensive．The average（平均的） price of a household printer is around $1，700，not including the cost of the materials．
   But as the technology develops，it shouldn't be long before disadvantages are improved．Only time will tell where this new technology will take us．

Answer 1

分析 這篇短文主要介紹3D打印技術的發展及帶給人們生活的變化，當然3D打印技術現在還存在著許多的不足，但是作者相信這些不足會在不久的將來得到改善．

解答 61．B．細節理解題．根據Ten years ago people could only see 3-D printing in science fiction（虛構的） movies．，可知十年前人們只有在科幻電影中看到三D打印，故選B．
62．C．推理判斷題．根據In the future，it is expected（期待） that the printer will make human organs（器官） to save more lives．可知現在人們還不能制作人體器官，故選C．
63．A．推理判斷題．上文描述的都是三D打印的優點，后面發生轉折可知是指其不足，故選A．
64．C．是非判斷題．根據上文提到不足中有一點是太貴及后文But as the technology develops，disadvantages will be improved可知這一缺點會得到改善，故選C．
65．B．主旨大意題．根據短文描述，可知本文重點講述了3D打印給人們帶來的變化．故選B．
