The Pacific island nation of Nauru used to be a beautiful place. Now it is an ecological disaster area. Nauru's heartbreaking story could have one good consequence-other countries might learn from its mistakes.

For thousands of years, Polynesian people lived in the remote island of Nauru, far from western civilization. The first European to arrive was John Fearn in 1798. He was the British captain of the Hunter, a whaling ship. He called the island Pleasant Island.

However, because it was very remote, Nauru had little communication with Europeans at first. The whaling ships and other traders began to visit, bringing guns and alcohol. These elements destroyed the social balance of the twelve family groups on the island. A ten-year civil war started, which reduced the population from 1,400 to 900.

Nauru's real troubles began in 1899 when a British mining company discovered phosphate(磷酸盐)on the island. In fact, it found that the island of Nauru was nearly all phosphate, which was a very important fertilizer for farming. The company began mining the phosphate.

A phosphate mine is not a hole in the ground; it is a strip mine. When a company strip-mines, it removes the top player of soil. Then it takes away the material it wants. Strip mining totally destroys the land. Gradually, the lovely island or Nauru started to look like the moon.

In 1968, Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate.

Unfortunately, the leaders invested the money unwisely and lost millions of dollars. In addition, they used millions more dollars for personal expenses. Soon people realized that they had a terrible problem—their phosphate was running out. Ninety percent of their island was destroyed and they had nothing. By 2000, Nauru was financially ruined. Experts say that it would take approximately$433, 600, 000 and more than 20 years to repair the island. This will probably never happen.

1.What was Nauru like before the Europeans came?

A. Rich and powerful]

B. Modern and open

C. Peaceful and attractive

D. Greedy and aggressive

2.The ecological disaster in Nauru resulted from .

A. soil pollution

3.Which of the following was a cause of Nauru's financial problem?

A. Its leaders misused the money

B. It spent too much repairing the island

C. Its phosphate mining cost much money

D. It lost millions of dollars in the civil war.

4.What can we learn about Nauru from the last paragraph?

A. The leaders will take the experts' words seriously

B. The phosphate mines were destroyed

C. The island was abandoned by the Nauruans

D. The ecological damage is difficult to repair.

Wheels are everywhere around you and me, yet no one knows exactly when the first wheel was invented or what it was used for. We do know, however, that they existed over 5,500 years ago in ancient Asia.

The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5,100 years old. Evidence suggests that wheels for transport didn’t become popular for a while, though. This could be because animals did a perfectly good job of carrying farming tools and humans around.

But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren't going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modern road design.

In the mid-1700s,a Frenchman came up with a new design of road--a base layer (层)of large stones covered with a thin layer of smaller stones. A Scotsman improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same time, metal hubs(the central part of a wheel)came into being, followed by the pneumatic tire (充气轮胎) in 1846. Alloy wheels were invented in 1967, sixty years after the appearance of tarmacked roads(柏油路). As wheel design took off, vehicles go faster and faster.

1.What might be the reason why transport wheels wasn’t that popular for some time?

A. Few knew how to use transport wheels.

B. Humans carried farming tools just as well.

C. Such animals as horses and bulls were still a good means of transport.

D. The existence of transport wheels was not known.

2.How is the last paragraph mainly developed?

A. By giving examples.

B. By following time order

C. By making comparisons.

D. By making classifications.

3.What is the passage mainly about?

A. The beginning of road design.

B. The history of public transport.

C. The developmentt of transport wheels.

D. The invention of fast-moving vehicles.

See a cellphone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hitting “print” on your computer.
You might find it hard to believe that you could actually “print” an object like you would a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays ink onto paper line by line, modern 3D 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 3D printer uses are mainly plastic, resin(树脂) and certain metals. The thinner each layer is—from a millimetre to less than the width of a hair—the smoother and finer the object will be.
This may sound like a completely new technology, but the truth is that 3D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.
Last year, though, saw a big change in the 3D printing industry—printers became much cheaper. For example, 10 years ago a desktop 3D printer might have cost £20,000, while now they cost only about £1,000, according to the BBC.
Taken out of the factory and introduced to more diverse and common uses, 3D printing can create just about anything you can think of—flutes , bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one.
However, as 3D printing becomes more common, it may bring about certain problems—such as piracy. “Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3D printer, who will visit a retail store again?” an expert in 3D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3D printer to print out a fully functioning gun?

1.According to the article, in the future, the 3D printing technology will _______.
A. enable people to make better purchases online

B. change the way we make many products
C. be applied as widely in our daily life as computers
D. shorten the time it takes for people to get what they buy online

2.What happened in the 3D printing industry last year?
A. The 3D printing technology was taken out of the factory.
B. The 3D printing technology began to be used in various fields.
C. The 3D printer was used for medical treatment for the first time.
D. The 3D printer became more affordable for consumers.

3.What is the best title of the passage?
A. Great Demand for 3D Printers B. Technology in the Future
C. Online Shopping Disappearing D. Printing out Everything

4.How is the last paragraph developed?
A. By giving examples.

B. By making comparisons.
C. By analyzing the cause and effect.

D. By presenting research findings.
