advise 后接动词作宾语时,要用动名词,不用不定式；但若其后接的动词前有宾语,此动词用作宾语补足语时,则此动词要用不定式.即说 advise doing sth (建议做某事)或 advise sb to do sth (建议某人做某事).类似情况的还有 allow(允许),permit(允许),forbid(禁止)等动词,即：
allow doing sth 允许做某事,allow sb to do sth 允许某人做某事；
permit doing sth 允许做某事,permit sb to do sth 允许某人做某事；
forbid doing sth 禁止做某事,forbid sb to do sth 禁止某人做某事.
