On the surface of Jupiter's moon Europa, water remains frozen, but the gravitational force of Jupiter and its other moons cause contractions that may generate so much heat that it would melt ice below Europa's surface.


moons cause contractions that may generate so much heat that it would melt

moons cause contractions, with enough heat generated for melting

moons causes contractions that may generate enough heat to melt

moons, causing contractions, may generate so much heat to melt

moons, which causes contractions, may generate enough heat for melting

题目分析:


选项分析:

A选项:结果状语从句so much heat that it would melt ice below Europa’s surface应改为不定式短语to melt  ice below Europa’s surface。这点考查了不定式和从句的区别。用之于本题,由于变化部分是generate的宾语的补足语,所以应根据generate在本题中的约束力来判断。显然地,“产生”可以控制“热量融化冰块”这个动作的发生与否,应该选择不定式的形式。

B选项:介词短语for melting ice below Europa’s surface应改为不定式短语to melt  ice below Europa’s surface,该错误在原理上同选项(A)。

C选项:Correct. 本选项在语法和逻辑上均是正确的。

D选项:本选项的generate的主语是the   gravitational force,在逻辑上,地心引力本身(the gravitational force)是无法产生热的(如果能产热的话,那我们早都热死了),所以理应是收缩力(contractions)产生热量。

E选项:generate的主语错误同(D);介词短语for melting ice below Europa’s surface错误同选项(B)。
