1 . New England holds some special museums. They are devoted largely or entirely to the work of just one person. And they are the artists’ birthplaces or onetime homes. Here are four examples of such museums.

Cyrus E. Dallin Art Museum

The name Cyrus E. Dallin (1861-1944) might not be familiar, but several of the artist’s sculptures (雕塑) are, especially those related to Native Americans. A good example is his “Appeal to the Great Spirit” standing in front of the Museum of Fine Arts. Born in Utah, he lived in Arlington for the final four decades of his life. The museum is in the Jefferson Cutter House, an 1830 Greek styled building.

Norman Rockwell Museum

Rockwell (1894-1978) was America’s well-known artist. The museum, founded in 1969, moved into its present location, Robert A.M. Stern-designed building in 1993. Its 998 paintings and drawings are the largest single collection of Rockwell's artworks.

Edward Gorey House

Edward Gorey (1925-2000) was an artist, but he was also an author and clothes designer. Gorey bought this 18th-century house in 1979 and lived there for the rest of his life. Edward Gorey House is also known as the Elephant House. Gorey had respect for animals. The activities of the house, from art education to exhibits, show Gorey's support of animal well-being.

Gibert Stuart Birthplace and Museum

Gilbert Stuart (1755-1828) is responsible for what may well be the most familiar work of any American artist, His drawing of George is the basis of the first president’s portrait (画像) on the dollar. Stuart painted more than a thousand portraits throughout his life.

2 . Coral reefs are some of the most diverse and valuable ecosystems on Earth. Coral reefs support more species per unit area than any other marine (海洋的) environment, including about 4,000 species of fish, 800 species of hard corals and hundreds of other species. Scientists estimate that there may be millions of undiscovered species living in and around reefs. This biodiversity is considered the key to finding new medicines for the 21st century. Many drugs are now being developed from coral reef animals and plants as possible cures for cancer, viruses, and other diseases.

Healthy coral reefs support fisheries as well as jobs and businesses through tourism and recreation. About half of all managed fisheries depend on coral reefs and related habitats for a part of their life cycles. The National Marine Fisheries Service estimates the commercial value of U. S. fisheries from coral reefs is over $ 100 million, Local economies receive billions of dollars from visitors to reefs through diving tours, recreational fishing trips, hotels, restaurants, and other businesses based near reef ecosystems.

Coral reef structures also buffer (缓冲) shorelines against 97 percent of the energy from waves, storms, and floods, helping to prevent loss of life, and property damage. When reefs are damaged or destroyed, the absence of this natural barrier can increase the damage to coastal communities from normal wave action and violent storms. Several million people live in U. S. coastal areas near coral reefs. Some coastal development is required to provide necessary infrastructure (基础设施) for coastal residents and the growing coastal tourism industry.

Despite their great economic and recreational value, coral reefs are severely threatened by pollution, disease, and habitat destruction. Once coral reefs are damaged, they are less able to support the many creatures that live on them and the communities near them. When a coral reef supports fewer fish, plants, and animals, it also loses value as a tourist destination.
