1. Each language has means to express the past, present and future, the so called real time. The English language, similarly to other languages, has also devices informing about how the activity was performed. Thus, in addition to the past-present-future dimension, the tenses hold information if, for example, a given activity is performed habitualy, had been performed before another past activity, the speaker wants to emphasize completion of an action, and the like.

2. The English tenses can be depicted in a table whose one dimension corresponds to the real time and another one to the mode of action.

Future-in-the-Past
NB: The Future-in-the-Past is a real time dimension which expresses actions which were in the future at the time of speaking. However, the time of speaking was in the past. (for example: Last time I saw you you were about to apply for a new job). It is also used in the Reported Speech to report sentences expressed originally in any of the future tenses.
Remember also that whatever mode of activity is expressed by a given tense, the tense remains GRAMATICALLY what its name indicates. For example, the Present Perfect can be used to express past actions whose time is not definite. However, gramatically, the Present Perfect tense remains PRESENT. It is important to remember that when using the Reported Speech with the SEQUENCE OF TENSES. Please note that the Simple Past tense is used to express past actions whose time is definite. Thus, both the Present Perfect and the Past Simple can be used to express past actions, albeit their diferent aspects, but GRAMATICALLY the Present Perfect is always PRESENT and the Past Simple is PAST. The implications of real time vs. grammatical tense are reflected in the Reported Speech with the Sequence of Tenses.

4. As you can see, the division of the tenses into sixteen different ones is logical. Can you think of the English names of the tenses to fill in the table below? Some of the names have been already supplied. What are the remaining names? The next slide reveals all the names.

6. In order to form sentences in a given tense you should know its structure. The structure consists of an auxiliary verb and a verb carrying the menaing. For example, in the sentence I have lived in Paris for three years the verb ”have” only helps to form the tense (Present Perfect), hence the name auxiliary. The verb ”live” carries the meaning. The auxiliary verb, or verbs, is/are the same for all sentences formed in a given tense. The meaning-carrying verbs do change.
The table below provides structures for some of the tenses. Can you provide, based on logical premises, the remaining structures?
