Years before the advent of plate


       tectonics―the widely accepted theory,


       developed in the mid-1960’s, the holds


Line that the major features of Earth’s surface


  (5)       are created by the horizontal motions


of Earth’s outer shell, or lithosphere―


a similar theory was rejected by the


geological community.  In 1912, Alfred


Wegener proposed, in a widely debated


(10)       theory that came to be called continental


drift, that Earth’s continents were mobile.


To most geologists today, Wegener’s

The origin of Continents and Oceans


appears an impressive and prescient


(15)       document, containing several of the


essential presumptions underlying plate


tectonics theory: the horizontal mobility



of pieces of Earth’s crust; the essential
difference between oceanic and conti-


(20)       nental crust; and a causal connection


       between horizontal displacements and


       the formation of mountain chains.  Yet


despite the considerable overlap


between Wegener’s concepts and the


(25)       later widely embraced plate tectonics


theory, and despite the fact that conti-


nental drift theory presented a possible


solution to the problem of the origin of


mountains at a time when existing expla-


(30)       nations were seriously in doubt, in its


day Wegener’s theory was rejected


by the vast majority of geologists.


             Most geologists and many historians


today believe that Wegener’s theory


(35)      was rejected because of its lack of an


adequate mechanical basis.  Stephen


Jay Gould, for example, argues that


continental drift theory was rejected


because it did not explain how continents


(40)       could move through an apparently solid


oceanic floor.  However, as Anthony


Hallam has pointed out, many scientific


phenomena, such as the ice ages, have


been accepted before they could be fully


(45)       explained.  The most likely cause for the


rejection of continental drift―a cause


that has been largely ignored because


we consider Wegener’s theory to have


been validated by the theory of plate


(50)       tectonics―is the nature of the evidence


that was put forward to support it.  Most


of Wegener’s evidence consisted of


homologies—similarities of patterns and


forms based on direct observations of


(55)       rocks in the field, supported by the use


of hammers, hand lenses, and field note-


books.  In contrast, the data supporting


plate tectonics were impressively


geophysical—instrumental determinations


(60)       of the physical properties of Earth gar-


nered through the use of seismographs,


magnetometers, and computers.


Q27:


It can be inferred from the passage that geologists today would be most likely to agree with which of the following statements about Wegener’s The Origin of Continents and Oceans?






A       It was a worthy scientific effort that was ahead of its time.



B       It was based on evidence that was later disproved.



C       It was directly responsible for the acceptance of the theory of plate tectonics.



D       It has been disproved by continental drift theory.



E       It misrepresented how horizontal displacements cause the formation of mountain chains.




答案是A,但个人觉得应该是C,文中第13行到第17行:Wegener’s The origin of Continents and Oceans appears an impressive and prescient document, containing several of the essential presumptions underlying plate tectonics theory


大家觉得呢?

C 是错的。作者说W的理论containing several of the essential presumptions underlying plate tectonics theory,只是一个事实,可能理论之间有传承关系,也可能只是巧合。说derictly responsible肯定不对。

那进一步请教:哪边可以证明A呢?

同意楼上的。这个词很关键!
