Question

阅读理解 　　Sabine Island, near Greenland, was first discovered by the British geographer Sir Edward Sabine in 1823, but an 1869 map showed it was actually a quarter of a mile farther west than its discoverer had mapped．This interested Alfred Wegener, a young geographer working in Greenland in 1910．He thought the error(误差)too great to be explained． 　　Wegener himself took measurements and found that since 1869 the island had moved another five eighths of a mile．After checking the position of other Arctic landmasses, he concluded that all of them were drifting(漂移)westward at different speeds． 　　From this finding, Wegener developed his floating continent theory．He imagined an original super continent making up the infant(未成年的)earth, finally the mass broke up into several pieces－the present continents．The continents do seem to fit together like pieces of a puzzle, and what’s more, some of the mountain ranges(山脉)of different continents line up rather well, as if the landmasses were at one time connected．However, believable as Wegener’s argument appeared, many geographers refused to accept it．Exactly how the continents were formed is still a leading mystery(谜)in geography, though today many geographers are returning to the continental drift theory． (1) Sabine Island was first discovered and mapped by _________． [　　] A． the map makers of 1869 B． geographers of Greenland C． a British geographer D． Alfred Wegener (2) The 1869 map showed that _________． [　　] A． Sir Edward Sabine had made a mistake B． Sabine Island was farther west than its discoverer had mapped C． Sabine Island was moving constantly D． Sabine Island was farther away from Greenland (3) Wegener’s discovery led him to conclude that． [　　] A． both the two earlier maps were in error B． the Arctic landmasses were slowly drifting westward C． all the continents were drifting slowly away from one another D． Sabine Island was one part of Greenland (4) From the passage we can conclude that _________． [　　] A． Wegener like to make things for granted B． Wegener had a true scientific attitude C． how the continents were formed is found out D． the continental drift theory needs further testing

Answer 1

答案：1．C;2．B;3．B;4．B;
解析：

(1)	文章第一句“Sabine lsland…was first discovered by the British geographer”，以及“But an 1869 map showed it was actually a quarter of a mile farther west than its discoverer had mapped”表明，英国地理学家Sir Edward不久发现了Sabine lsland而且为其绘了图。
(2)	关键句“but an 1869 map showed it was actually a quarter of a mile farther west than its discoverer had mapped．”。
(3)	关键句“After checking the position of other Arctic landmasses, he concluded that all of them were drifting westward at different speeds”。
(4)	从文中看Wegener的大陆漂移说是有科学依据的，说明他具有实事求是的科学态度，尽管许多地理学家不愿意接受，但现在又回到大陆漂移说这一理论上来。文章并没有说大陆漂移说需要进一步验证，故不可选D。
