因为原因需要一个完整句子表达,所以排除BE,A较之CD,主要是A的句意更直接,简洁。一个to do 不定式做ability的同位语,成了一个完整的意义补充;虽有capability of to do 的例子,但局限于后接两个并列的不定式,单独用还是倾向于ing,另外的一个原因前面的人已经说过了,所以不选D;细看C,简化结构后为:capability of sth in doing.注意这个多出来的In,有了它,味道完全变了,本来不应该加,有了它就指在dealing这方面的能力被削弱了,而没有起到应该起的补充解释作用。此外,capability多用于指人的可发展的,应用的才能,工作能力。在这里讲硫化物,还是用ability好些。 做点补充:查了朗文字典。上面明确说有capability to do sth., 举例:A willingness and a capability to change are necessaryto meet the market's needs. 但是请注意观察这个例子,capability不是单独使用的,后面的不定式明显是同时做willingness和capability的同位语。
