How to change sentence in present participle

The present participle is always formed by adding the suffix -ing to a verb. When used with an auxiliary verb like "is," "am," "are," "was" or "were," the present participle forms a compound verb that describes an action that is in progress. For example: She is babysitting tonight.  Adding -ing to the base form of a verb creates the present participle. For example, eat is the base form of the verb to eat. ... Present participles always end in -ing. Other examples of present participles include swimming, laughing, and playing.
