***** NOT A TEACHER *****
Hello, Elitez:
Kindly remember the appearance of infinitives and gerunds, and then you will not be confused in the future.
I have made up these sentences:
1. To eat ice cream is fun. (infinitive).
2. Eating ice cream is fun. (gerund)
3. I like reading newspapers. (gerund)
4. I like to read newspapers. (infinitive)
Note: Sometimes the "to" of the infinitive is optional after certain verbs (such as "help"): "He helped me (to) do it."
Note: Sometimes the "to" of the infinitive must NOT be used after certain verbs (such as "see"): "I saw him do it."
(Books use the term "bare infinitive" for an infinitive without the word "to.")
