　　Explorers had been landing in America for some time before English settlers arrived in what is now Jamestown, Virginia, in 1607. But it was in that spot on the James River that English colonization（殖民化） began, and with it, the history of America.

　　James I was the king of England at that time, and he had granted approval for a group of businessmen who were part of the Virginia Company to settle in this new land. In all, 214 people set sail for America. They reached it on May 14, 1607. Very soon after they landed, the English found themselves under attack from Algonquins, a native American tribe(部落) who had been living in that area for some time. The English managed to drive off the attackers and stay there.

Under the leadership of Captain John Smith, the English built a fort（城堡）and other buildings designed to protect their new colony. They also found friendly native Americans, like Powhatan, who was willing to trade with them.

　　There was a terrible winter in 1609 and only 60 of the 214 settlers survived, which was also hard on Powhatan's tribe and other neighboring native Americans.

　　One of the main crops grown by the English settlers was tobacco, which they sold to native Americans and to people back in England, beginning in 1612. Tobacco became a very popular crop because it was easy to grow and because it brought in so much money.

　　Once the money started flowing in regularly, the Jamestown colony grew, as did other settlements in Virginia and in other states along the eastern coastline.

　　America's first elected assembly (议会), the House of Burgesses, met in Jamestown for the first time on July 30, 1619. The year 1619 also saw another significant development: the first arrival of black workers on boats from Africa. These men and women were originally servants, who worked a small piece of land for a few years and then got to keep the land as owners. Jamestown was also the capital of Virginia and remained so until 1698.

　　When it comes to medical care, many patients and doctors believe "more is better." But what they do not realize is that overtreatment-too many scans, too many blood tests, too many procedures-may bring harm. Sometimes a test leads you down a path to more and more testing, some of which may be attacking, or to treatment for things that should be left out.
