Hello my friend.
This time we begin a new unit, where we’ll learn a lot of the things that will help you with you learning of a new language, English. In other occasions we mentioned the past tense and the regular or irregular verbs, now is time to explain the auxiliary verb “Did.” You know when we speak about the past tense make a reference to make a reference to an event that happened before, like yesterday, the last week, the last month, even 1 second ago. All that points in the space are considered like past.
The structure for positive sentences in the simple past tense is:
- subject + main verb (past)
The structure for negative sentences in the simple past tense is:
- subject + auxiliary verb (did) + not + main verb (base)
The auxiliary verb did is not conjugated. It is the same for all persons (I did, you did, he did etc). And the base form and past form do not change. Look at these examples with the main verbs go and work:
Exception! The verb to be is different. We conjugate the verb to be (I was, you were, he/she/it was, we were, they were); and we do not use an auxiliary for negative and question sentences. To make a question, we exchange the subject and verb. Look at these examples:
See you next time.
