2 . Tayka Hotel De Sal

Where: Tahua, Bolivia

How much: About $95 a night

Why it’s cool: You’ve stayed at hotels made of brick or wood, but salt? That’s something few can claim. Tayka Hotel de Sal is made totally of salt - including the beds (though you’ll sleep on regular mattresses and blankets). The hotel sits on the Salar de Uyuni, a prehistoric dried-up lake that’s the world’s biggest salt flat. Builders use the salt from the 4,633-square-mile flat to make the bricks, and glue them together with a paste of wet salt that hardens when it dries. When rain starts to dissolve the hotel, the owners just mix up more salt paste to strengthen the bricks.

Green Magic Nature Resort

Where: Vythiri, India

How much: About $240 a night

Why it’s cool: Riding a pulley (滑轮) -operated lift 86 feet to your treetop room is just the start of your adventure. As you look out of your open window - there is no glass! -you watch monkeys and birds in the rain forest canopy. Later you might test your fear of heights by crossing the handmade rope bridge to the main part of the hotel, or just sit on your bamboo bed and read. You don’t even have to come down for breakfast - the hotel will send it up on the pulley-drawn “elevator”.

Dog Bark Park Inn B&B

Where: Cottonwood, Idaho

How much: $92 a night

Why it’s cool: This doghouse isn’t just for the family pet. Sweet Willy is a 30-foot-tall dog with guest rooms in his belly. Climb the wooden stairs beside his hind leg to enter the door in his side. You can relax in the main bedroom, go up a few steps to the loft in Willy’s head, or hang out inside his nose. Although you have a full private bathroom in your quarters, there is also a toilet in the 12-foot-tall fire hydrant outside.

Gamirasu Cave Hotel

Where: Ayvali, Turkey

How much: Between $130 and $475 a night.

Why it’s cool: This is caveman cool! Experience what it was1 like 5,000 years ago, when people lived in these mountain caves formed by volcanic ash. But your stay will be much more modern. Bathrooms and electricity provide what you expect from a modern hotel, and the white volcanic ash, called tufa, keeps the rooms cool, about 65 ℉ in summer. (Don’t worry - there is heat in winter.)

For years scientist have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more     1     than the air outside. It may be one hundred times worse.

Indoor air pollution can cause a person to feel tired, to     2     eye-pain, headache and other problems. Some pollutants can cause breathing disorders, diseases of blood and even cancer. Most scientists     3     that every modern house has some kind of indoor pollution. People began to     4     the problem in the early 1970s, when it was that builders began making houses and offices which did not waste energy. To do this they built buildings that     5     the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to     6     harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control     7     for building green plants. Scientist do not really know how plants control air pollution. They believe that a plant’s leaves take in the pollutants. In exchange the plant produces oxygen     8     its leaves and through its tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each     9     different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place.
