2º Bachillerato Grammar Notes: to+ -ing

A note to complete your infinitives and gerunds explanation:

To + ing form

To  is really two different words:

1.      A sign of the infinitive.

2.      A preposition.

So, when to is a preposition and it is followed by a verb, we use the –ing form.

            Ex.       I’m looking forward to seeing you at Christmas.

                         Do you object to working on Sundays?

                         I’m no used to driving in London.

                         I prefer riding to walking.

 If you’re not sure whether to is a preposition or not, try putting a noun after it. If to cannot be followed by a noun, it is not a preposition and –ing is not used.

Common examples:

                        Look forward to + ing

                        Object to + ing

                        Be used to + ing

                        In addition to + ing

                        Be accustomed to + ing
