     Martin Frobisher,born in Yorkshire,went to London as a boy to be educated by a relative.

He showed no talent for book learning,so his relative sent him to sea.Before reaching manhood,

Frobisher had been on two voyages to the Guinea Coast.On the second he was captured and

handed over to the Portuguese garrisoning (驻守) Sao Jorge da Mina (now Elmina,Ghana),who

allowed him to return to England.

     By the 1570s,England had largely abandoned hope of finding a Northeast Passage to Asia,

and thoughts turned to the Northwest.Frobisher worked together with Michael Lok,a man of some

wealth and learning.Frobisher's first voyage,in 1576,took him to Frobisher Bay in Baffin Island.  

     English investors (投资者),including Queen Elizabeth,poured money into  Lok's Company of

Cathay.Frobisher sailed again in 1577,this time to ship home what he mistakenly thought was

goldbearing minerals.Lok still felt hopeful and sent Frobisher back in 1578.This time the mariner

discovered the Hudson Strait.He followed the strait for nearly 200 miles,believing it to be a more

promising Northwest Passage than Frobisher Bay.He brought home more dirt and rocks,but English

confidence had gone；Lok went to a debtors' prison and Frobisher sought other employment.

     Frobisher accompanied Sir Francis Drake to the West Indies in 1585～1586.When Philip Ⅱ's

Spanish Armada (无敌舰队) entered the English Channel in 1588,Frobisher's part in the fighting was

successful and he received knighthood (爵士爵位).He died of a wound received near Brest,where

he had been sent to relieve the siege (解除包围).He lived just long enough to be taken back to Plymouth.
