Infinitives and -ing forms

July 22nd, 2011 in Improve English

Prepositions are not normally followed by infinitives in English. Instead we use the –ing form of the following verb.

He insisted on coming with me. (NOT He insisted on to come with me.)
I hate the idea of getting married. (NOT I hate the idea of to get married.)
I am not very good at singing. (NOT I am not very good at to sing.)
I am thinking of writing a novel. (NOT I am thinking of to write a novel.)
He is confident of winning. (NOT He is confident of to win.)

After certain adjectives and verbs both infinitives and –ing forms can be used. There is often a difference of meaning.

Afraid, for example, can be followed by –ing forms or infinitives.

I am not afraid of telling the truth. OR I am not afraid to tell the truth.

Certain

Certain is followed by an –ing form when you are referring to the feelings of the person you are talking about.

He seems very certain of winning.

Certain is followed by an infinitive when you are referring to your own feelings.

The repairs are certain to cost a fortune.

Interested

I am interested in learning more about the Indian civilization.
