Right Form of Verb
This section focuses on using the correct verb forms in different contexts, primarily focusing on tenses and sequence of tenses.
Tense
Tense indicates the time of an action or state, whether it is in the past, present, or future. The reference text provides a comprehensive overview of the 12 tenses in English, along with their structures and example sentences.
The 12 Tenses
-
Present Tenses:
- Present Indefinite: Expresses habitual actions, general truths, or future events in subordinate clauses. (Structure: Subject + V1 + Object)
- Present Continuous: Describes ongoing actions or temporary situations in the present. (Structure: Subject + am/is/are + Ving + Object)
- Present Perfect: Indicates actions completed in the past with relevance to the present or actions that started in the past and continue into the present. (Structure: Subject + have/has + V3 + Object)
- Present Perfect Continuous: Emphasizes the duration of an action that started in the past and continues into the present. (Structure: Subject + have/has + been + Ving + Object + for/since + time)
-
Past Tenses:
- Past Indefinite: Expresses actions completed in the past. (Structure: Subject + V2 + Object)
- Past Continuous: Describes actions in progress at a specific time in the past. (Structure: Subject + was/were + Ving + Object)
- Past Perfect: Indicates an action completed before another action in the past. (Structure: Subject + had + V3 + Object)
- Past Perfect Continuous: Emphasizes the duration of an action that occurred before another action in the past. (Structure: Subject + had + been + Ving + Object + for/since + time)
-
Future Tenses:
- Future Indefinite: Expresses actions that will happen in the future. (Structure: Subject + shall/will + VB + Object)
- Future Continuous: Describes actions that will be in progress at a specific time in the future. (Structure: Subject + shall/will + be + Ving + Object)
- Future Perfect: Indicates actions that will be completed by a certain time in the future. (Structure: Subject + shall/will + have + V3 + Object)
- Future Perfect Continuous: Emphasizes the duration of an action that will be in progress before another action in the future. (Structure: Subject + shall/will + have + been + Ving + Object + for/since + time)
Sequence of Tenses
Sequence of tenses refers to the logical relationship between the tenses of verbs in a main clause and its subordinate clause(s).
- General Rule: If the main clause verb is in the present or future tense, the subordinate clause verb can be in any tense. If the main clause verb is in the past tense, the subordinate clause verb should also be in the past tense.
- Exceptions:
- Universal truths, habitual actions, historical facts, and scientific truths are expressed in the present indefinite tense, even if the main clause is in the past tense.
- In comparisons using ‘than’ or ‘as’, the tense in the subordinate clause depends on the context and meaning.
- In sentences with two or more past actions, the earlier action is expressed in the past perfect tense, and the later action is in the past indefinite tense.
