【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(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() 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!

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(duì)于人們是有幫助的而且如果被壞人利用也有可能是危險(xiǎn)的。

1A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。

2B歸納理解題。根據(jù)第二段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() by layer and like magic the object is produced.可知第一設(shè)計(jì)一個(gè)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。

3C詞義猜測(cè)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.

4D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(huì)用3D打印機(jī)打印槍,可知還沒有打印,故選D。

5B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(xiǎn)的,故選B.

【題目】

The Erie Canal was the first important national waterway built in the US. It crossed New York State(州)from Buffalo on Lake Eric to Albany on the Hudson River. It joined the Great Lakes with the Atlantic Ocean.

Over the canal industrial goods(工業(yè)產(chǎn)品)could flow into the west, and materials could pour into the east. The Erie Canal helped New York develop into the nation's larges city.

The building of the canal was paid for completely by the state of New York. It cost $7,143,789, but it soon gained its price many times over. Between 1825, when the canal was opened, and 1882, when toll charges(過運(yùn)河費(fèi))were stopped, the state collected $121,461,891.

For a hundred years before the Erie Canal was built, people had been talking about a canal to join the Great Lakes and the Atlantic Ocean. The man who planned the Erie Canal and carried the plan through was De Witt Clinton. At that time some people laughingly called it "Clinton's Ditch(溝)". Clinton talked and wrote about the canal and drew up plans for it. He and Governor Morris went to Washington in 1812 to ask for help for the canal, but they were unsuccessful.

Clinton became governor of New York State in 1817, and shortly afterwards, on July 4,1817, broke ground for the canal in Rome of New York State. The first part of the canal was completed in 1820. As the canal grew, towns along its course developed fast. The length of the canal is 363 miles.
