- Present Perfect Continuous: Emphasizes the duration of an ongoing action. Example: He has been working here for five years.
1.2 Past Tenses
- Past Simple: Denotes completed actions at a specific time in the past. Example: She watched a movie yesterday.
- Past Continuous: Describes ongoing actions in the past interrupted by another event. Example: They were playing football when it started to rain.
- Past Perfect: Indicates an action completed before another past action. Example: I had finished my homework before dinner.
- Past Perfect Continuous: Focuses on the duration before a specific past point. Example: He had been studying for hours when I arrived.
1.3 Future Tenses
- Will Future: Spontaneous decisions, promises, or predictions. Example: I will call you tomorrow.
- Be Going To: Planned actions or intentions. Example: She is going to start a new job.

Proper sentence structure is essential for clarity and coherence. This section covers basic sentence types, word order, and common errors.

- Complex Sentences: Include an independent clause and one or more dependent clauses. Example: Although he was tired, he finished his homework.
- Compound-Complex Sentences: Have multiple independent clauses and at least one dependent clause. Example: She was hungry, so she cooked dinner because she was tired.
2.3 Word Order and Syntax Rules
