单项选择题 8. Plymouth Plymouth, town (township), Plymouth county, southeastern Massachusetts, U.S. It lies on Plymouth Bay, 37 miles (60 km) southeast of Boston. It was the site of the first permanent settlement by Europeans in New England, Plymouth colony, known formally as the colony of New Plymouth. The town was founded by Pilgrims (separatists from the Church of England) who, in their search for religious toleration, had immigrated first to the Netherlands and then to North America. Sailing in the Mayflower from Plymouth, England, the settlers reached the shores of Cape Cod in November 1620, and an exploring party arrived in the Plymouth area on December 21 (now celebrated as Forefathers’ Day). According to tradition, the Pilgrims landed on Plymouth Rock on December 26 and built their first fort and watchtower on Burial Hill. Half their number died that first winter and were buried on Cole’s Hill, which was later leveled and planted in grain so that the Native Americans could not judge the extent of the colony’s depletion. Although never officially incorporated, the town was recognized in 1633 as the seat of Plymouth colony, which was absorbed into Massachusetts Bay Colony in 1691. Its seaside location and historic associations make Plymouth an outstanding summer resort. A tourist-based economy is supplemented by light manufacturing, the production of computer software, fishing, and various services. Seafaring was the heart of the early economy of the community, and active wharves and boatyards remain. Numerous historic attractions include Plymouth Plantation (a re-creation of the original Pilgrim village), Pilgrim Hall Museum (built in 1824), Harlow Old Fort House (a building depicting 17th-century household occupations of Plymouth women), and Mayflower II, a goodwill ship built at Brixham, England, that sailed across the Atlantic Ocean in 53 days in 1957. Many early colonial houses in the town have been restored, including the Richard Sparrow House (1640), the Edward Winslow House (1699), and the Jabez Howland House. Plymouth Rock, first identified in 1741, became a symbol of freedom in 1774 when it was split by being dragged to Liberty Pole Square in pre-Revolutionary agitation. It now rests on its original waterfront site under a portico of granite. On a hill behind the town is the 81-foot (25-metre) National Monument to the Forefathers (Pilgrim Monument), dedicated in 1889. Plymouth includes most of the 17-square-mile (44-square-km) Myles Standish State Forest. Area 96 square miles (248 square km). 16.
