1 . Everglades National Park is the largest subtropical (亚热带的) wilderness in the country.    1    It is also the third largest national park in the lower forty-eight states, after Death Valley and Yellowstone. Each year, more than one million people visit the Everglades.

    2    The expansive wetlands stretch across more than six hundred thousand hectares. It is a place where plants and animals from the Caribbean Sea share an ecosystem with native North American species.

Unlike most other national parks, Everglades National Park was created to protect an ecosystem from damage. The Everglades is home to about fifteen species that federal officials say are threatened and endangered.    3    .

In addition, more than three hundred fifty bird species and three hundred species of fresh and saltwater fish live within the park. The Everglades is also home to forty species of mammals and fifty reptile species.

    4    They include what is said to be the largest growth of mangrove trees in the western world. Gumbo-limbo trees, known for their peeling red skin, strangler figs and royal palms are also among the area's plant life. The country's largest living mahogany tree also lives in the Everglades.

In recent years, environmental experts have learned about the damage to the Everglades. They say the balance of nature there has been destroyed.    5     However, efforts to protect the area are continuing so people from all over the world may continue visiting this biological treasure.

A．The future of the Everglades is not clear.

B．Visitors to the Everglades will see many exotic plants.

C．The park is home to several rare and endangered species.

D．Experts believe that the Everglades has a very bright future.

E．The park is very beautiful and attracts millions of tourists every year.

F．They include the Florida panther, the American crocodile and the West Indian manatee.

G．The Everglades is considered one of the great biological wonders of the world.

2 . In the basement of a landmark 27-story tower in Stockholm, Petterson is hoping to sow the seeds of an indoor urban farming revolution. He is the chief executive of Plantagon, a new urban farming factory, set to kick off operations in the basement of an office block in the Swedish capital.

He is by no means the first enthusiast for indoor farming, which has become increasingly fashionable in recent years. Claims for the practice of growing food in basements range from feeding people in desert environments to transforming the negative environmental effects of monoculture farming.

Plantagon's early promises reflect this new optimism. Petterson calls the farm's approach "agritechture": the combination of agriculture, technology and architecture hoping to revolutionize how we live and eat.

The term may be new, but the concept isn't. Indoor farming is made possible by agricultural technologies such as hydroponics (growing plants without soil) and aeroponics (in which plants are grown in air over containers). Food can be produced without direct sunlight or soil.

Plantagon plans to grow high-value foods in a pumice-like material rather than soil. Water for the plants is measured precisely. It will also dehumidify (除湿) the air and reuse any extra water to ensure zero waste. Compared with conventional agriculture, it will need much less water to produce the same amount of crops.

Energy is also a key issue for indoor urban farms, which have to create artificial sunlight. Although advances in the efficiency of LED lights have helped bring down energy consumption in recent years, plants use only about 1 percent of the artificial light produced. This leads to a great waste of energy, most of which disappears as heat. The basement farm will capture around 70 percent of this wasted heat and pipe it into the heating system of the office block above. Oxygen produced by the plants will be sent to office workers via the building's air conditioners.
