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(无穷的)．All the user has to do is 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(按)“print”，the 3-D printer spreads the materials layer(层)by layer and like magic the object is produced．
The first 3-D printer was invented in 1 986 by 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(提款机盗刷器)．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!

A．a-b-c-d B．d-c-b-a C．a-c-d-b D．d-a-b-e
( )3．According to the passage，people have NOT yet produced________with a 3-D printer．
A．a gun B．some furniture
C．a man-made ear D．ATM skimmers
( )4．What does the writer think of the 3-D printer?
