The unknown world’s mystry

    The sea is the biggest unknown part of our world. It covers seventy-one percent of the earth. There is still much to be discovered about this vast blanket of water. If the waters of the ocean could be removed, the sea floor with its wide valleys, irregular mountains and rivers in the sea would be an unbelievable sight.

Tourism under the deep blue sea

    Tourists can now explore the world beneath the waves without ever getting wet. From tourist submarines (潜艇) to underwater dining, undersea tourism is making a big splash.

Tourist submarines

    The popularity of submarine tours has grown rapidly in the last decade. Now, tourist submarines operate in more than 20 locations worldwide, including the waters around Okinawa and Taiwan’s Green Island. The submarines carry nearly 2 million tourists each year. Large windows offer passengers spectacular views as the submarines explore colorful coral reefs and sunken ships. Most one-hour tours cost about US $80.

Under water dinning

    For a more upscale experience, tourists can enjoy fine dining under the sea. Last summer the Hilton Maldives Resort opened the world’s first underwater restaurant, Ithaa. Diners walk down a staircase into the restaurant, which rests 35 feet beneath the waves of the Indian Ocean. Transparent walls surround the dining area, and you can treat guests to a panoramic (全景) ocean view.

    But this excellent view doesn’t come cheap. The tasting menu costs US $200 per person. Be sure to make reservations early, too. The restaurant seats only 14 people.

What does the author want to tell us in Paragraph 1?

A. The sea is the biggest unknown part of our world.    B. The sea covers 71% of the earth.

C. Some information about the sea floor.   D. The reasons for researching undersea tourism.

What does the author really mean by saying “undersea tourism is making a big splash” in Para2 ?  

A. Undersea tourism is a new fashion in travelling. B. Your clothes will be made wet by the water splash. C. Undersea tourism is dangerous. D. There is still a long way for undersea tourism to go.

Which of the following statements about tourist submarines is RIGHT?

A. Tourist submarines only have a history of about 10 years.

B. There are tourist submarines in every part of the world now.

C. Tourist submarines have carried about 2 million tourists so far.

D. People can enjoy tourist submarines in the waters around Okinawa.

The walls of the restaurant Ithaa are most probably made of               .

A. stone         B. brick           C. glass          D. steel

In the late 1960's, many people in North America turned their attention to environmental problems, and new steel-and-glass skyscrapers were widely criticized. Ecologists pointed out that a forest of tall buildings in a city often overburdens public transportation and parking lots.

Skyscrapers are also consumers and wasters of electric power. In one recent year, the addition of 17 million square feet of skyscrapers office space in New York City raised the peak daily demand for electricity by 120,000 kilowatts--enough to supply the entire city of Albany, New York, for a day.

Glass-walled skyscrapers can be especially wasteful. The heat loss ( or gain) through a wall of half-inch plate glass is more than ten times that through a typical brick wall filled with insulation (绝缘) board. To lessen the strain on heating and air-conditioning equipment, builders of skyscrapers have begun to use double-glazed panels of glass, and reflective glasses coated with silver or gold mirror films that reduce glare(眩目的光) as well as heat gain.

However, mirror-walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings.               

Skyscrapers put a strain on a city's sanitation facilities(卫生设备),too. If fully occupied, the two World Trade Center towers in New York City would alone produce 2.25 million gallons of wastes each year-as much a city the size of Stanford, Connecticut, which has a population of more than 109,000.

Skyscrapers also affect television reception, block bird flyways and air traffic, In Boston in the late 1960's, some people even feared that shadows from skyscrapers would kill the grass on Boston Common. Still ,people continue to build skyscrapers for all the reasons that they have always built them-personal pride and the desire of owners to have the largest possible amount of space to rent.
