Many verbs are used in continuous tenses. Here are some examples:
Present continuous – I’m working at the moment.
Past continuous – Jack was cooking dinner when I arrived.
Future continuous – I will be playing tennis this time tomorrow.
Present perfect continuous – She’s been working here for three years.
Generally, continuous (or progressive) tenses are used to describe what is happening at a particular moment in time. The focus when using continuous tenses is always on an action in progress. However, there are some important exceptions to using continuous tenses. Most importantly, there are a number of common non-continuous verbs that are never or rarely used with continuous forms. These verbs fall into a few categories:
Mental and Emotional States
