To map Earth's interior, geologists use a network of seismometers to chart seismic waves that originate in the earth's crust and ricochet around its interior, most rapidly traveling through cold, dense regions and slower through hotter rocks.


interior, most rapidly traveling through cold, dense regions and slower

interior, which travel most rapidly through cold, dense regions, and more slowly

interior, traveling most rapidly through cold, dense regions and more slowly

interior and most rapidly travel through cold, dense regions, and slower

interior and that travel most rapidly through cold, dense regions and slower

选项分析:

A选项:slower不正确。由于本句中的slow是在描述地震波传播的速度的,所以其应该修饰travel这个动词,应该用副词的slowly,而不是slower这个形容词

B选项:which是一个定语从句,应该就近修饰一个名词。由于这里travel是复数,但其身前几乎没有复数名词,因此该定语从句没有先行词。(waves虽然是复数,但是和这个定语从句之间隔了一个层级,无法修饰到该名词)

C选项:Correct. 本选项在逻辑和语法上均是正确的。现在分词短语traveling most rapidly through cold, dense regions是伴随状语就近修饰waves ricochet around its interior这个句子,travel的逻辑主语为waves。

D选项:
travel和ricochet做为合句不正确,应让travel做伴随状语。这是因为,合句是并列关系,状语是从属关系,本题中,“地震波在冷的条件下更快”是“地震波在内层跳动”的一个属性,即,跳动这个行为的速度属性。因此,两件事只能是从属关系,而不能是并列关系。另外,slower错误同(A)。

E选项:
本选项错误同(D)。
