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
题目分析:
略
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)。
ADE用了形容词SLOWER错误,并且D是从属关系,地震波在内层跳动,穿过了冷的,热的,B中定语从句找不到先行词
B选项中 非限制性状语从句就近修饰interior 不符合语义 故排除
B选项:which指代不明确;
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:and that--wordy;
请老师解答?
ricochet:to hit a surface and come off it fast at a different angle 弹开;反弹出去
slower是形容词,不是副词。
C is not modifying the interior but it is modifying the whole preceding phrase.
the comma + ing phrase can be used to show cause and effect relationship as well as to give extra info about the preceding phrase.
Here the modifier is performing the latter part.
And between slower and more slowly we require adverb to modify travelling. So more slowly is correct
这个解释更合理。
A, slower比较对象没有,and前面也找不到和slower的平行
B, which修饰问题,;and more slowly如果是和most rapidly平行的话,那不应该and前有逗号,and加逗号分割成独立部分,作用相当于分号;
C至少平行没有错误
D,E,slower都找不到平行的对象
不过我迷惑的是,怎么判断这个travelling是修饰从句还是主句呢?如果是修饰主句,那肯定就不对了,所以这里会不会出现修饰不清晰的情况??
C项中ing状语和-ly副词都修饰的是前面的谓语动词,不存在歧义。
E项根据语义判断不是并列关系,而是从属关系,且不要只看开头就选了,后面先是rapidly又是slower,一个修饰动词一个修饰名词,明显混乱了。
