Seeing someone who seems to be walking on a cloud sounds like a dream. But this scene indeed exists --- and it isn't just in your head. It's a popular attraction in the South American country of Bolivia called the Salar de Uyuni. The area covers a large amount of white, glistening salt and runs across 10,582 kilometers of the Altiplano and you can even see it from space.

What's special about the Salar? This salt flat can create an endless natural mirror (鏡子), which gives you an amazing experience. On a still day, a thin layer of water covering the salt changes the salt flat into "The World's Largest Mirror" reflecting the sky. Those who are lucky enough to see this natural wonder will tell you how difficult it is to find out the dividing line between the sky and land.

Some 40,000 years ago, water from the surrounding mountains gathered here and there were no outlets (出口) where the rainfall could flow out. So a huge lake was formed with natural salt inside. Over time, about 25,000 years ago, a rise in temperatures reduced the amount of rainfall in the area. The climate from wet to dry caused the water to slowly evaporate (蒸發(fā)). About 10,000 years ago, the body of water dried up and a deep layer of salt flat was left behind.

With about 10 billion tons of salt lying around it, it's no surprise that salt production in the Salar is a big business. But the real treasure lies under the surface of the salt flat, where around 70% of the world's lithium (鋰) reserves can be found. The lithium is used for powering mobile phones, laptops, electric cars and this resource could be of great value.

New research suggests that growing trees and other plants near factories could reduce pollution by almost one- third.

More plant life may even cost less and be more effective (有效的) than technology designed to cut pollution, a new study found. Researchers collected data about air pollution and plant life in 48 cities. They studied public records from every city.

The researchers knew that trees and plants are taking in large amounts of harmful air. So they tried to find out whether new plants could reduce air pollution.

The study tried to show how this vegetation (植被) could reduce the pollution, including the production of energy from coal, oil and gas. The researchers found that growing plants, where possible, could cut air pollution by about 27 percent in the areas studied. They also found that in 75 percent of the areas, it would cost less to use plants and trees to reduce air pollution than to add new air cleaning technology.

"The fact is that traditionally, especially as engineers, we don't think about nature," Dr. Bakshi, said. "We just focus on putting technology into everything."

"To solve air pollution problems, people need to start learning from the nature and respecting it," Bakshi said. He added that nature-based methods could result in "win-win" solutions that save money and are better for the environment.

The study couldn't tell which kinds of trees or plants would be best at reducing air pollution. But Bakshi said they might make a difference in air quality, so further study is needed.

The researchers said that more trees and plants could help lower air pollution levels in both cities and rural areas. However, success rates (比率) would be different depending on how much land can be used and its air quality levels.

1.The researchers found that plants were ________ air cleaning technology.

A.better than B.worse than C.as cheap as D.as good as

2.Most engineers think ________ is more important in reducing air pollution.

A.nature B.cost C.location D.technology

3.What do "win-win" solutions refer to in Paragraph 6?

A.Building more factories to develop technology.

B.Reducing air pollution with less money.

C.Saving more money by developing technology.

D.Developing technology and reducing pollution.

4.What can we learn from the passage?

A.1/3 of the pollution can be reduced by technology.

B.The study has found out the most effective plants.

C.Plants improve the air quality in cities and the country.

D.Air quality levels mainly decide the success rates.
