Re: home educator If you contrast the two aspects, the progressive (or continuous) aspect shows that something is incomplete and the perfect shows some form of completion. They both have a present and a past form depending on whether the completion, or lack of it, is relevant or related to now or to a time in the past. There's a lot of debate and disagreement about how many tenses there are in English, but I think the two-tense model has an elegant clarity- we have the simple, progressive and perfect forms of the present and the past, and even the perfect progressive for partial completion. |
