Question

非谓语动词的单选题,急!
Exciting as its special effects are_____, there is too much violence in the film.
A. to watch B. to be watched C. watching D.being watched
还原后是As its special effects are exciting to watch,这个to watch在句中到底是做什么成分?状语还是宾补?我看有的参考书又说的做主语补足语.难道要看作It is+adj.+to do的结构吗?但是如果是这种形式主语的句子,真正的主语是to watch special effects are exciting,前面并没有it作形式主语啊.只有一个As,是看作让步状语从句吗?

Answer 1

As在这里引导的确实是一个表示让步的状语从句,意思是,尽管.AS的这种用法常采用倒装形式,如：
Teacher as he is,he often reads with the students.
形容词exciting后接动词不定式的用法与hard,easy,difficult的用法一种,是一种主动形式表示被动含义.
Its special effects are exciting to watch.
=To watch its special effects is exciting.
=It is exciting to watch its special effects.
