The damaged part of the machine is rather difficult ().
a.to repair b.repairing c.to be repaired d.being repaired

答案是A,有有些想不通,为什么不能选C?请指教!谢谢!

某些动词不定式的主动形式表被动含义 a.当nice,easy,fit,hard,difficult,important,impossible,pleasant, interesting等形容词后跟不定式作状语,而句子的主语又是动词不定式的逻辑宾语时,这时常用不定式的主动形式表达被动含义。如: Japanese is not difficult to learn.日语并不难学。(指日语被学) The water is unfit to drink.这水不适合喝。(指水被喝) The piece of music is pleasant to hear.这首音乐听起来很悦耳。(指音乐被听) This book is easy to read.这本书读起来很容易。(指书被读) b.当动词不定式在名词后面作定语,不定式和名词之间有动宾关系时,不定式的主动形式表示被动含义。如: I have a lot of work to do today.我今天有很多工作要做。(work to do指被做的工作) He has three children to look after.他有三个孩子要照看。(children to look after指孩子被照看) 注意:如果以上句型用动词不定式的被动形式,其含义有所区别。如: I have some clothes to be washed.我有些要洗的衣服。(衣服不是自己洗) c.在there be...句型中,当动词不定式修饰名词作定语时,不定式用主动或被动式,其含义没有什么区别。如: There is a lot of homework to do(to be done).有很多家庭作业要做。 There are some clothes to wash(to be washed).有些衣服要洗。

习惯性的

A
difficult/easy/comfortable/uncomfortable 这类词出现的时候,主动表被动
一种语法,不是习惯性
