题目分析:
本题的难度主要出现在选项(C)和选项(D)中。
选项分析:
选项A:划线部分身前的现在分词短语responding to the public's fascination with-and sometimes undue alarm over-possible threats from asteroids是伴随状语,其主语必须和它所修饰的句子主语相同,即,a scale。在逻辑上,“回应公众过分担心的”很显然应该是“天文学家”,而不是“量度表”。
选项B:伴随状语的逻辑主语错误同选项(A)。
选项C:本选项有两处错误。第一,a scale身后的定语应该由不定式短语to rate改为动名词短语for rating,这点考查了不定式和ing的区别。用之于本题,在主句“科学家研发了一个量度表”这个事件发生时,“给撞击地球的可能性打分”这个事件依然处于恒定的状态中。这是因为,当一个量度表被研发好了的时候,不一定要马上开始依照这个量度表来评分,可能只是一个参考标准,即,“打分”这个事件在主观上不一定发生,需要用ing形式。
第二,rate身后的宾语how likely a particular asteroid or comet will be to collide with Earth是宾语从句,其核心词是从句中的谓语动词collide(撞击)。但在逻辑上,真正被“打分”的对象应该是小行星撞击地球的“可能性”而不是“撞击”这个事件本身(打出来的分,肯定是某一个或几个小行星撞击的百分比嘛)。因此,rate宾语的核心词应是likelihood。
选项D:Correct. 本选项在语法和逻辑上均是正确的。
选项E:likelihood的修饰部分,即,a particular asteroid or comet that may collide with Earth,的核心词为“一个特定的行星或彗星(a particular asteroid or comet)”。在逻辑上,应是“特定行星撞击的可能性”,而不是“特定行星的可能性”。因此,likelihood的修饰部分应用同位语从句。
definition of "likelihood": How probable does this event seem right now?
There's no "future likelihood" here. In the future, the event either happens or doesn't happen.
intend meaning : How likely is it NOW that a comet/asteroid WILL STRIKE Earth?
有谁可以帮忙分析一下how likely a particular asteroid or comet will be to collide with Earth这个句子的结构吗?为什么核心词是collide?
我! 因为how likely引导的是一个从句,这里是做rate的宾语从句,从句的核心词,必然是句子里的谓语动词~
哈哈谢谢男神

E:“应是 ‘特定行星撞击的可能性’,而不是 ‘特定行星的可能性’ 。因此,likelihood的修饰部分应用同位语从句。”
C我觉得还有一个错误就是彗星撞击地球应该是主动的而不是被动,所以will be to是错的。我错选了E没有看清意思
同意!

选项C:刚上来把develop当做use来看,看了解释后,事后诸葛觉得相比use, develop,开发出来更像是一个状态性的动作,和rate之间还有些距离,因而约束力不强。另个一个错误感觉应该是be likely 与will有重复的嫌疑。
遇到 从句和of短语的对比 会出现核心词判断的问题 以及直接加从句和名词加从句也涉及
