Verbs not used in a progressing form (-ing) are usually related to mental states or the senses.
• Remember, know, believe, understand, forget,
• Like, prefer, need, want
• Agree, mean, seem
Also with no progressive form :
• Contain, belong, concern
• Consist, involve, depend (It depends on …)
•
• Sometimes both tenses are possible with different meanings:
– He has a new car (possess) v He’s having lunch (eating)
– I think he’s right (opinion) v I’m thinking of/about changing my job (I’m undecided)
– I (can) see your point. v I’m seeing (ie meeting) the director tomorrow.
•
• Note: if no progressive tense in the present, there is none in the present perfect.
(e.g. I’ve known him for a long time, not « I’ve been knowing him »)
