This is a good link with exercises to work on the topic and this one has explanations to start with, but pay attention to the level you need and/or want. Although you are in the intermediate level, I'd rather you use the basic level in the beginning to check you don't have any doubt, but, as you can see, you have many exercises to work with. Another good link is this one with different levels as well.
This is the video from British Council to show you how the pattern verb works and this link is quite simple but it's a start to refresh the principal verbs followed by infinitive or gerund.
As a summary, you may use this diagramme:
- VERBS followed by:
- -ing form (gerund): verbs related to likes and dislikes, followed by preposition and with reference to past or previous actions; e.g. I enjoy listening to music, My father gave up smoking last year or She denied being guilty (compare it with the verb "to refuse")
- infinitive : related to future actions
- with TO: I'd like/want to go with you or She refused to go there
- without TO (bare infinitive): She made me laugh a lot or Let me tell you something
- both (infinitive or gerund)
- with a change in meaning:
- I always remember to buy some bread for my mother (I never forget to buy some bread for my mother)
- I remember buying some bread with my mother as a child (it's a memory)
- without changing the meaning: I began reading - I began to read
If you want to have a good review about this topic, go to Test English and then start with the exercises.
Keep in mind the importance of the verb pattern when you use introductory verbs in Reported Speech:
