Sulfur dioxide, a major contributor to acid rain, is an especially serious pollutant because it diminishes the respiratory system’s ability to deal with all other pollutants.
(A) an especially serious pollutant because it diminishes the respiratory system’s ability to deal
(B) an especially serious pollutant because of diminishing the respiratory system’s capability of dealing
(C) an especially serious pollutant because it diminishes the capability of the respiratory system in dealing
(D) a specially serious pollutant because it diminishes the capability of the respiratory system to deal
(E) a specially serious pollutant because of diminishing the respiratory system’s ability to deal
答案给(a) 但是我不知道为什么
这题应该是考麻烦字specially, especially, capability, ability
1.我查了字典, specially是表有特殊目的的特别,ex:specially trained police dogs后面常接动词, 而especially是表强调不同点或程度的的特别ex:especially in winter, especially fond of
2.ability:someone's level of skill at doing something感觉是指人
capability:the natural ability, skill, or power that makes a machine, person, or organization able to do something, especially something difficult 感觉指非人
