| Martha's Vineyard (葡萄园) got its name from its discoverer, Artholomew Gasbnold, who named it after his wife Martha, and it was also in memory of the thick growth of wild vines (葡萄) on the land. The island of Martha's Vineyard lies south of Cape Cod off the Southern eastern coast of Massachusetts, United States. It is nearly 20 miles long and runs from 2 to 10 miles in width. There are wide, hard beaches on the southern side. The north is hilly, but in the south and eastern parts there are wide areas of open land covered with wild flowers. The island was discovered early in the 17th cen－tury. The Indians were quiet and friendly, and the newcomers fished for a living, making a lot of money from whaling (捕鲸). With the decline (衰落) of whaling and sailing ships, Martha's Vineyard was almost for－gotten until about 60 years ago when people began to buy the old houses of the whaling captains and the sheds of the fishermen near the beaches. Now people go there year after year for their summer holidays. |
