Important Rules with questions

Rule -1

Preposition + gerund (verb + ing)

A preposition always takes a gerund, not an infinitive.

For example,

•Anand insisted on Leaving at once .

•She was granted leave for visiting her uncle.

•There is no harm in repeating the experiment.

•He stopped me form going home.

Note: ‘But’ or ‘except’ used as a preposition takes an

infinitive not a gerund. For example, He does nothing

but / except watch TV all the time.
