Some English verbs do not form a continuous tense, hence the name non-continuous verbs. These include for example the verb "to love", "to like" or "to belong".
Other English verbs have several meanings, one of which usually do not form a continuous tense. These verbs are called mixed verbs.. These include for example the verb "to have" or "to be".
If these verbs occur in a sentence, where we would normally use the Present continuous tense, we must replace it with the Present perfect.
