Summary: Four Traditional Future Tense Forms

No., Future tense, Structure, Example

1. Simple Future: Subject + will + V1 | I will study physics.

2. Future Continuous: Subject + will be + V-ing | I will be studying physics.

3. Future Perfect:  Subject + will have + V3 | I will have completed my research.

4. Future Perfect Continuous: Subject + will have been + V-ing | I will have been studying for three hours.

Note: V1 means the base form of a verb, and V3 means the past participle. In traditional English grammar teaching, these are called the four future tenses. In modern linguistic analysis, English does not have a separate inflectional future tense comparable to its past tense; future meaning is generally expressed through modal auxiliaries, present-tense forms, and other constructions.

Total: 30 major topics, covering the four traditional future forms, alternative future expressions, grammatical structures, advanced usage, common errors, and practical applications.
