加doing一般表示，正在做，或者是想待会做，而加to do 表示想做，但可能做不了！应该没有太大的规律，每个动词所对应的词组是一定的！在特殊情况下，你会理解什么时候用doing 什么时候用to do
下动词和短语只能接to do:
agree consent decine refuse offer promise choose decide determine attempt intend manage fail ask hope want expect long wish tend desire seek claim plan prepare learn mean volunteer pretend dare afford arrange appear bear beg care commence demand dislike endeavour fear happen hesitate neglect pledge prefer propose resolve threaten undertake venture contrive condescend contract aspire hasten plot proceed tell advise show aim prove swear vow

说实话我还没找出什么规律，建议你还是多背一些固定词组。如果遇到一个不认识的生词，只好凭语感碰运气。如果知道是什么意思而不知道用法，可以找一些意思类似的类比一下。总之，多记词组才是硬道理。
这个没有什么规律的，只有靠经验判断，见得多了，也就了解得多
