Abstract
Some verbs can take as their complement either to-infinitive or -ing participle. Among those verbs are aspectual verbs like start, begin, continue and cease. These verbs, however, cannot always take the two types of complements. Then we assume that there is a semantic difference between the two types of aspectual verb complements themselves and that the analysis of the difference will provide a semantic solution to the problem of the complement selection of predicates. The present paper concerns itself with the two types of aspectual verb complements which can be distinguished on the analogy of the aspectual distinction of perception verb complements.
