-ing forms 7

Some verbs and adjectives can be followed by either -ing forms (‘gerunds’) or infinitives.

With some of these verbs and adjectives, there is a difference of meaning.

infinitive is used mostly in announcements of bad news.

4 advise, allow, permit and forbid
In active clauses after these verbs, we use an -ing form if there is no object. If there is an object we use an infinitive. Compare:

5 see, watch and hear
After these verbs, the difference between object + -ing form and object + infinitive is like the difference between progressive and simple tenses. With -ing forms the verbs suggest that one pays attention to events or actions that are already going on; infinitives usually refer to complete events /actions which are seen/heard from beginning to end. (Note that these verbs are followed by the infinitive without to.) Compare: ?
– I looked out of the window and saw Mary crossing the road.
I saw Mary cross the road and disappear into the post office.
– As I passed his house I heard him practising the piano.
