(Wiezbicka, 1988: p.69)

speech act verbs such a recommend or suggest refer to some possibilities that the addressee should consider, rather than to some actions that the addressee should perform Speech act verbs which do refer to the addressee's actions — such as ordeor beg — do not take gerundive complements:
X ordered Y  to do Z/*doing Z.
X recommended/suggested/proposed doing Z.
