Verb + verb

Listen!
When you have VERB 1 + VERB 2, in Spanish, usually verb + infinitive:
Quiero caminar.                            Me gustaría caminar
Odio caminar.                                Prefiero caminar.
Decidí caminar.                             Terminé de caminar.
Empecé a caminar.                       Intenté caminar.
Necesito caminar.                        No puedo caminar.        
 (Alguna excepción: disfruto caminando).

In English, three possibilities:
VERB 1 + TO-infinitive,
VERB 1 + bare infinitive (=infinitive without TO),
VERB 1 + -ING.
 Which one is right? It depends on VERB 1. There are no real rules. Examples:

VERB + TO-infinitive:
I promised to keep it. (=quedárselo)                          She would like to keep it.
She tried to keep it.                                                           I want to keep it.

VERB + BARE INFINITIVE:
You can't keep it.                                  Could I have some more?
I'll (will) leave it.                                  What time shall we meet?

VERB + -ING:
We enjoy swimming.                                   They all love travelling.
I hate cooking.                                               Stop laughing!
I finished doing the washing-up.           I hate being late.
Do you like dancing?
