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 (打印機(jī))!

The possibilities of 3-D printing seem endless. All the user has to do is to design (設(shè)計(jì)) 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 (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 (家具) made from old fridges. And doctors have used 3-D printing to print human body parts! A newspaper 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 printinggets 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!

【3】The underlined word “gets into the wrong hands” in the fourth paragraph might mean__________ in English.

A.the hands caught by the printerB.to get into trouble

C.the hands used in a wrong placeD.to do something bad

【3】D

【4】C

【解析】

本文介紹了3D打印技術(shù)，利用3D打印機(jī)，你可以打印任何想要的東西。第一個(gè)3D打印機(jī)于1986年被一位美國(guó)人發(fā)明。2011年，有人利用3D打印技術(shù)打印了提款機(jī)盜刷器。未來(lái)，你可能無(wú)法想象沒(méi)有3D打印的日子。

【1】細(xì)節(jié)理解題。題意：誰(shuí)發(fā)明了第一臺(tái)3D打印機(jī)？根據(jù)The first 3-D printer was invented in 1986 by an American, Charles Hull.故選A。

【2】文章順序題。a. Choose a material.選擇一種材料；b. The 3-D printer spreads the material.3D打印機(jī)延展材料；c. Press the print button.按下打印按鈕；d. Use a computer to design an object.使用電腦設(shè)計(jì)一個(gè)物件。根據(jù)All the user has to do is to design (設(shè)計(jì)) 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，可知，先設(shè)計(jì)，然后選擇材料，按下按鈕，打印機(jī)工作，故順序?yàn)?/span>d-a-c-b,故選D。

【3】詞義猜測(cè)題。題意：下劃線“gets into the wrong hands”在英文中是什么意思？A. the hands caught by the printer手被打印機(jī)卡住了；B. to get into trouble陷入困境；C. the hands used in a wrong place手用錯(cuò)地方了；D. to do something bad做壞事。根據(jù)These were placed on an ATM and stole over $400,000 from users of the ATM.可知，有人利用3D打印技術(shù)，做壞事，故選D。

【4】觀點(diǎn)態(tài)度題。題意：作者認(rèn)為3D打印機(jī)怎么樣？A. It is necessary only for our work. 這只對(duì)我們的工作是必要的；B. It is too expensive for most people. 對(duì)大多數(shù)人來(lái)說(shuō)太貴了；C. It is helpful but dangerous. 這是有益的，但也是危險(xiǎn)的；D. It is useless in our daily life.它在我們的日常生活中是無(wú)用的。根據(jù)But for better or for worse, 3-D printing has been put into use.故選C。
