问题描述：
More TV programs,according to government to officials,will be produced people’s concern 选A不选C?
29.More TV programs,according to government to officials,will be produced people’s concern over food safety.
A.to raise B.raising
C.to have raised D.having raised
答
to do 是不定式的通常形式,to have done的不定式的过去式,在必须使用不定式的结构中,如果不定式的动作和主句 谓语的动作同时发生,或者不定式的动作在主句谓语动词之后发生,也就带着“现在”、“将来”（仅仅是相对于谓语动词的,和真正的现在没有关系）的意味,那么就用to do,如果不定式的动作在主句谓语的动作之前发生,并且说话的人要强调这种先后关系,那么就要用to have done .
因此,上面这句话,提高关注是将来要发生的事.所以选A
