📚 Explanation of Grammar Rules Used:

#### 1. Affirmative Sentences (Subject + Verb)
- Use base form of verb for I, you, we, they.
- e.g., *I come*, *You go*, *We have*
- Add -s/-es for he, she, it (third person singular).
- e.g., *This one has...*

#### 2. Negative Sentences (Subject + don’t/doesn’t + base verb)
- For I, you, we, they → use don’t
- e.g., *I don’t understand*, *We don’t have*
- For he, she, it → use doesn’t
- e.g., *It doesn’t make*

> ❗ Note: After *don’t* or *doesn’t*, always use the base form of the verb (no -s).

#### 3. Questions (Do/Does + Subject + Base Verb)
- For I, you, we, they → use do
- e.g., *Why do you speak?*, *What do you think?*
- For he, she, it → use does
- e.g., *Does she go?* (Not used here)

> ❗ In questions, the subject comes after the auxiliary (*do/does*), and the main verb stays in base form.

#### 4. Special Case: Question with “I” — #16
The prompt says: *(I/not/know/?)*
→ Literal construction: Do I not know him now?
→ More natural: Don’t I know him now? (contraction of "do not" → "don't")

Both are grammatically correct, but “Don’t I know him now?” is more common in everyday English. Since the worksheet asks for Present Simple and gives the words, either could be accepted — but “Don’t I know him now?” is preferred.
