2. Locate the base form of the verb: To determine the ending of the present participle, you need to know the base form of the verb. The base form is the simplest form of the verb, usually found in the dictionary.

3. Identify the ending of the present participle: Present participles always end in "-ing." For example, the present participle of the verb "run" is "running."

4. Identify the ending of the past participle: In most cases, the past participle of regular verbs ends in "-ed" or "-d." For instance, the past participle of the verb "walk" is "walked."

5. Remember the exception for irregular verbs: Irregular verbs do not follow the same pattern for forming their past tense and past participle. Each irregular verb has its own unique form for the past and past participle. For example, the past participle of the irregular verb "go" is "gone."
