How to use 'OUGHT TO' in sentences as an Auxiliary Verb?

Last lesson in our free MT course blog dealt about the usage of 'MUST' as an auxiliary verb. Now we will see about the uses of  “Ought to”: 1. To show or express duty or obligation (Ought to is stronger than Must) or expectations. 2. It is used in the future in the past tense.  Some of the rules for ought to are: 1. In simple present tense this auxiliary ‘ought to’ is used in the present form of the verb. 2. In present continuous tense this auxiliary ‘ought to be’ is used in the verb in the present form of –ing. 3. In future in the past tense this auxiliary ‘ought to have’ is used in the verb in the past participle of the verb.  4. In future in the past continuous tense this auxiliary ‘ought to have been’ is used in the verb in the present ending in –ing form. Whenever the sentence of the structure expresses duty or obligation, then some of the examples of the structures of the sentences are given below.

1. The passengers ought to report at the enquiry office in the arrival of the train. (This is in simple present tense form)
2. We ought to be leaving the station now.
3. The spectators ought not to go beyond this line. (This is in simple present tense form)
4. The teacher ought to be advising her students frequently about the discipline. (This is in present continuous tense form)
5. All of us ought to render help to orphanage. (This is in simple present tense form).
6. This film ought to do well at the box office. (This is in expectation-simple present tense form).

Whenever the sentence of the structure represents future in the past, then some of the examples of the structures of the sentences are given below.
1. You ought to have gone to the drama hall for the reception ceremony.
2. They ought not to have violated the college rules and regulations.
3. The week students ought not to have been spending much time on playing games. (This is in the future in the past continuous tense form)
