a) Future in the past: "should/would + verb"

The future in the past is used to talk about something that was going to happen in the future from a point of time in the past. The auxiliary verbs "should" and "would" are used to indicate the future.

Example: He said he would go to the party tomorrow.

b) Future continuous active: "will be + verb-ing"

The future continuous tense is used to describe an ongoing action that will be happening at a certain point in the future. The auxiliary verb "will" is used along with the present participle form ("-ing") of the main verb.

Example: She will be studying for her exams all night.

c) Future simple: "will + verb"

The future simple tense is used to express a future action or event that will happen at a specific time in the future. The auxiliary verb "will" is used along with the base form of the main verb.

Example: They will arrive at the airport at 7 PM.

d) Present indefinite: "verb"

The present indefinite tense is used to express habitual or regular actions in the present or general truths. There is no auxiliary verb used in this tense.

Example: She plays tennis every weekend.

e) Past indefinite: "verb-ed"

The past indefinite tense is used to express completed actions or events in the past. The main verb is used in its past participle form ("-ed" for regular verbs) or irregular form (for irregular verbs).

Example: I walked to the park yesterday.

In summary, each tense has its own usage and structure to express different points in time.
