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
答案选A，关于这道题的diminish后面的宾语，我想请问一下后面的ability是diminish的宾语，那后面的to deal是做为宾补么？还有就是deal前面的那个介词to是因为diminish来决定的还是ability来决定的啊？

sayysong

to deal with ... 是动词不定式做定语修饰 ability
由ability来决定，ability to do 跟be able to do一起记忆。

哦~~我还想请问一下，如何区分不定式是做的定语还是宾补呢？我一直分不清楚~~语法书越看越昏……

要理解句子的意思了，动词 to 动词的话是宾语，但是名词 to 动词的话，就是宾补
