Question

【题目】阅读理解C

Have you ever had dreams about building a robot? Or putting together a spaceship? Or even seeing your face made out of chocolate? Done. All you need is a 3-D printer!
The possibilities of 3-D printing seem endless. All the user has to do is to design an object on the computer and choose a material to print in. The printers print in hundreds of different materials including glass, sugar and even skin! When the user presses "print", the 3-D printer spreads the material layer by layer and like magic the object is produced.
The first 3-D printer was invented in 1986 by an American, Charles Hull. But 3-D printing has only become cheap enough recently for most people to use. Designers now use 3-D printing to create unusual things. The Dutch artist Dirk Vander Kooj prints furniture made from old fridges. And doctors have used 3-D printing to print human body parts! The Telegraph reported in February that scientists from Cornell Medical College even printed a man-made ear.
But like a lot of new technologies , if 3-D printing gets into the wrong hands, it can be dangerous. In 2011 a group of four men in the US used 3-D printing to produce ATM skimmers . These were placed on an ATM and stole over $400,000 from users of the ATM. It is terrible to think that criminals like them might one day use a 3-D printer to print a gun.
But for better or for worse, 3-D printing has been put into use. In a few years, you'll probably be wondering how you could ever live without your 3-D printer!

（3）The underlined word " gets into the wrong hands " in the fourth paragraph might meanin English.
A.the hands caught by the printer
B.to get into trouble
C.the hands used in a wrong place

Answer 1

【答案】
（1）A
（2）B
（3）D
（4）C
【解析】本文是一篇说明文。主要介绍了3D打印技术。3D打印机的使用顺序是：在电脑上设计物体，选择打印材料，按下打印按钮，打印机展开材料。设计者们现在使用3D打印技术创造出不寻常的事物，但是如果陷入不当的人的手里，也会是危险的，但不管怎么说，这项技术已经被使用，或许在未来人们的生活会离不开它。
（1）A。细节理解题。根据第三段“ The first 3-D printer was invented in 1986 by an American, Charles Hull.”可知，第一台3D打印机是在1986年被美国人Charles Hull发明的。故选A。
（2）B。理解排序题。根据第二段“All the user has to do is to design an object on the computer and choose a material to print in. 所有的使用者必须做的是在电脑上设计一个物体并且选择一种材料去打印”及“When the user presses "print", the 3-D printer spreads the material layer by layer and like magic the object is produced当用户按下“打印”时，三维打印机逐层将材料展开并像魔术一样产生物体”可知，3D打印机的使用顺序是：在电脑上设计物体，选择打印材料，按下打印按钮，打印机展开材料。故选B。
（3）D。同义句转换题。原文中的句子，get into陷入；wrong错误的，不适当的。原文可以翻译为陷入/落入不适当的人手里，也就是说被非法使用。to do something illegally意为非法做某事。故选D。
（4）C。细节理解题。根据第三段“Designers now use 3-D printing to create unusual things. 设计者们现在使用3D打印技术创造出不寻常的事物”及第四段“ it can be dangerous它会是危险的”可知，作者的观点里，3D打印技术是既有用又危险的。故选C。
