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（A）

(E) a specially serious pollutant because of diminishing the respiratory system’s ability to deal

答案是A,我选了B

the respiratory system不是人,怎么可以用's结构.

C. the capability of sth in doing sth的结构是不是有语法错误 ?还是仅仅因为ETS倾向于ability to do sth> capability of doing sth?

's结构越来越不严格啦,不能当axiom

because of 接动名词复杂结构是ETS所厌恶的;另外capability of XX , 做"XX能力"解 而不是"XX(所有)的能力",capability of the respiratory system错
