How do people traditionally manufacture (制造) things? They usually start with a sheet of metal, wood or other material and cut, drill (钻) and shave it to create a desired shape. Sometimes, they use a mold (模具) made of metal or sand, pour liquid plastic or metal into it and let it cool to create a solid part.

Now, a completely different method is gaining popularity.

On Oct. 9, 2013, London Science Museum kicked off its new exhibition, 3-D: Printing the Future, with over 600 3-D printed objects on display, including space probes (探测器), toy dolls and even human organs – basically any product you can think of, reported Live Science.

You might find it hard to believe that an object can actually be “printed out” like a picture. But it is not that hard to understand how it works. Just as a traditional printer sprays (喷洒) ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.

Instead of ink, the materials the 3-D printer uses are mainly plastic, resin (树脂) and certain metals. The thinner each layer is – from a millimeter to less than the width of a hair – the smoother and finer the object will be. And objects always come out in one piece, sparing you the trouble of putting different parts together afterward.

For example, 10 years ago a desktop 3-D printer might have cost £20,000 (200,000 yuan), while now it costs only about £1,000, according to the BBC. In fact, 3-D printers have been around for some time, but until recently they hadn’t been very popular since few people could afford them. Last year, though, saw a big decrease in the price of 3-D printers.

However, as 3-D printing technology becomes more commonplace, it may trigger certain problems. One of them is piracy (盗版). “Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3-D printer, who will visit a retail (零售的) store again?” an expert on 3-D printing told Forbes News.

Even more frightening, the world’s first 3-D printed gun was successfully fired in the US in May of this year, which means that 3-D printing could potentially give more people access to weapons.

1.According to the article, in the future, 3-D printing technology will probably ______.

A. change the way people make products

B. be applied as widely in our daily lives as computers

C. forbid many countries to make purchases of weapons

D. take the place of normal printers and save lots of energy

2.What was the big event that happened in the 3-D printing industry last year?

A. Over 600 3-D printed objects were on display in an exhibition.

B. 3-D printing technology came to be used in various fields.

C. The world’s first 3-D printed gun was successfully made.

D. The 3-D printer became more affordable for consumers.

3.What is the author’s attitude toward 3-D printing technology?

A. Amused. B. Objective.

C. Supportive. D. Negative.

The report came to the British on May 21, 1941. The German battleship (战列舰) Bismarck, the most powerful warship in the world, was moving out into the Atlantic Ocean. Her task: to destroy the ships carrying supplies (补给) from the United States to war-torn England.

The British had feared such a task. No warship they had could match the Bismarck in speed or in firepower. The Bismarck had eight 15-inch guns and 81 smaller guns. She could move at 30 nautical miles (海里) an hour. She was believed to be unsinkable.

However, the British had to sink her. They sent out a task force headed by their best battleship Hood to hunt down the Bismarck. On May 24, the Hood found the Bismarck.

It was a meeting that the German commander Luetjens did not want to see. His orders were to destroy the British ships that were carrying supplies, but to stay away from a fight with British warships.

The battle didn’t last long. The Bismarck’s first torpedo (鱼雷) hit the Hood, which went down taking all but three of her 1,419 men with her.

But in the fight, the Bismarck was a bit damaged. Her commander decided to run for repairs to France, which had at that time been taken by the Germans. The British force followed her. However, because of the Bismarck’s speed and the heavy fog, they lost sight of her.

For two days, every British ship in the Atlantic tried to find the Bismarck, but with no success. Finally, she was sighted by a plane from Ireland. Trying to slow the Bismarck down so that their ships could catch up with her, the British fired at her from the air. The Bismarck was hit.

On the morning of May 27, the last battle was fought. Four British ships fired on the Bismarck, and she was finally sunk.

Say (suppose) you are a 17th century construction worker who’s worked long and hard to build a splendid tower for the dead wife of your emperor.

Now say that the emperor orders your fingertips cut off so you can never build another one. Yes, that is the Taj Mahal, one of the most famous buildings in the world. And the tale behind the construction is just as impressive as the building itself.

First, there’s the emperor of northern India, Shah Jehan, also called the King of the World. In 1612, Shah Jehan married Mumtaz Mahal. Madly in love, they had 14 children over the next 20 years. But then sadness came. As Mumtaz was about to give birth to child number 14, she said she had heard her unborn baby cry out. It was a sign of death. And as Mumtaz lay dying, she asked Jehan to build a lasting memorial (纪念物) to celebrate their love.

When the heartbroken Jehan appeared eight days after his wife’s death, his people were shocked to see that his coal-black hair had turned snow-white.

Putting away his sadness, Jehan ordered his wife’s dying wish carried out. More than 20,000 workers labored nearly 22 years to complete the construction. In 1653, Jehan placed Mumtaz’s remains (遗体) in the center under the building.

And then, son number five, Aurangzeb, murdered his brothers and took over the power from his aging father. Jehan lived the rest of his days - eight years, to be exact - imprisoned not far from the Taj Mahal. Jehan was only allowed to climb onto the top of his prison to see the timeless treasure from a distance. But never again would he be allowed to visit it-until he was buried next to his wife.

Today 25,000 people visit the Taj Mahal each day. Though the reason for building the tower was a strange, sad story, those who see its breath-taking beauty are reminded of the happiness that inspired (激发……的灵感) its construction.

1.The first two paragraphs were written to show that ________.

A. the Taj Mahal is an unusual historic building

B. ancient Indian emperors were cruel

C. construction workers led a hard life in ancient India

D. India has some of the most famous buildings in the world

2.The Taj Mahal was first built as ________.

A. a prison B. a gift to Mumtaz

C. a memorial building D. a tourist attraction

3.We learn from the text that Mumtaz probably died in ________.

A. 1626 B. 1632 C. 1634 D. 1653

4.The underlined word “happiness” in the last sentence refers to ________.

A. the married happiness of the emperor and his wife

B. the great pleasure Jehan once found in exercising his power

C. the happiness Jehan felt on completing the Taj Mahal

D. the pleasure tourists experience when visiting the Taj Mahal.
