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(jì)) 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 thatcriminalslike 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-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.
A.技術(shù)員 B.軍人 C.罪犯 D.用戶
4.According to the passage, people have NOT yet produced _________ with a 3-D printer.

5.What does the writer think of the 3-D printer?

A Farewell Song
No dust is raised on the road wet with morning rain; 1.
I invite you to drink a cup of wine again;
West of the sunny pass no more friends will be seen. (Translated by Xu Yuanchong)
Time flies and you will soon be finished with junior high school.2.This feeling was shared more than 1,000 years ago, when the Tang Dynasty poet Wang Wei (701-761) had to say goodbye to his friend.
3.After the rain, the road is clean and free of dust, and the willows (柳樹) by the hotel are fresh and green. On this morning, Wang has to say goodbye to his friend Yuan Er, who would leave for a faraway place called Anxi in today's Xinjiang.
The last two lines are the most well-known.4.Although most cities in China were prosperous (繁華的) during the Tang Dynasty (618-907), the western areas were quite desolate (荒涼的).
The journey to the west would be full of hardship, Wang thought. So when Wang says “I invite you to drink a cup of wine again,” he is pouring his care and good wishes into the cup as well.5. Everyone wishes good luck before goodbye so the poem is really worth reading again and again.
A.A Farewell Song begins with a lovely morning scene.
B.The willows by the hotel look so fresh and green.
C.The poet invites Yuan to drink wine because he knows that life in Anxi will be tough.
D.It might be a little sad to say goodbye to your teachers and classmates.
E.This sincere love for his friend made this poem popular back then and it remains so today.
