[不定项选择题]共用题干 The First Settlement in North America
It is very difficult to saythat when colonization began.The first hundred years after Christo-pher Columbus’s journey of discovery in 1492 did not produce any settlement on the North Ameri-can continent but rather some Spanish trading posts further south,a great interest in gold and ad-venture,and some colorful crimes in which the English had their part.John Cabot,originally from Genoa but a citizen of Venice, was estahlished as a trader in Bristol,England,when he made a journey in 1497 .But his ship,the Matthew,with its crew of eighteen,did no more than see an island(probably off the New England coast)and return home.He and his son made fur-ther voyages across the north Atlantic,which enahled the English Crown to claima“legal”title to North America.But for a long time afterwards the Europeans,interest in America was mainly con-fined to the Spanish activities further south.
Th e fi rst heginning of permanent settlement in North America was nearly a hundred yearsa仁 ter Columbus'5 first voyage.The Englishman Sir Walter Raleigh claimed the whole of North Amer-ica for England,calling it Virginia.In 1585 he sent a small group ofpeople who landed in Roano-ke Island,but they stayed only for a year and then went back to England with another expedition, led hy Drake,in 1 5 87 .A second group who landed in 1 587 had all disappeared when a further expedition arrived in 1590.
The first permanent settlement in North America was in 1 607 .English capitalists founded two Virginia companies,a southern one hased in London and a northern one based in Bristol.It was decided to give the name New England to the northernarea.The first settlers in Virginia were lit-tle more than wage slaves to the company.All were men and the experiment was not very success-ful .Many died.Those who survived lived in miserable conditions.By 1619 the colony had onlya thousand people. The first attempt made by European people to settle down permanently in North America oc-curred in the 1580s.
A.Right
B.Wrong
C.Not mentioned
