Question

【題目】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(設(shè)計) an object on the computer and choose a material(材料) 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(層) 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 (提款機(jī)盜刷器). 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!

【1】 _______ invented the first 3-D printer.

A. Charles Hull B. Dirk Vander Kooj

C. A doctor called Cornell D. Four men in the U.S

A. a-b-c-d B. d-a-b-c

C. a-c-d-b D. d-c-b-a

【3】The underlined word “criminals” in the fourth paragraph might mean ______________ in Chinese.

【3】C

【4】D

【5】B

【解析】

試題分析：這篇短文主要介紹了3D打印技術(shù)的發(fā)明不僅對于人們是有幫助的而且如果被壞人利用也有可能是危險的。

【1】A細(xì)節(jié)理解題。根據(jù)The first 3-D printer was invented in 1986 by an American, Charles Hull.故選A。

【2】B歸納理解題。根據(jù)第二段All the user has to do is to design(設(shè)計) an object on the computer and choose a material(材料) 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(層) by layer and like magic the object is produced.可知第一設(shè)計一個物體，二是選擇材料，三是按下打印按鈕，四打印機(jī)傳輸材料。故選B。

【3】C詞義猜測題。根據(jù)like them指的是像上文中制造提款機(jī)盜刷器的人一樣的人，故是罪犯，故選C.

【4】D推理判斷題。根據(jù)It is terrible to think that criminals like them might one day use a 3-D printer to print a gun.有一天罪犯可能會用3D打印機(jī)打印槍，可知還沒有打印，故選D。

【5】B推理判斷題。根據(jù)But like a lot of new technologies, if 3-D printing gets into the wrong hands, it can be dangerous.可知作者認(rèn)為3D技術(shù)也是危險的，故選B.
