- To be: am, is, are, was, were, been, being

- To do: do, does, did
- Modal verbs: can, could, may, might, shall, should, will, would, must

#### Part 2: Irregular Verbs

Irregular verbs are verbs that do not follow the standard pattern of forming past tense or past participle forms. For example:
- Bit (past tense of "bite")
- Wrote (past tense of "write")
- Chose (past tense of "choose")

##### Sentences:
1. The dog bit the child.
- Underlined: bit
2. All fruits were eaten by the monkey.
- Underlined: eaten
3. We need to send the trucks over.
- Underlined: need (Note: "need" is irregular in some contexts, but here it is used as a modal verb-like structure. If strictly focusing on past tense/irregular forms, this might not apply.)
4. Lea wrote a letter to her dad.
- Underlined: wrote
5. The policeman wants to lay his hands on the thief.
- Underlined: wants (Note: "want" is irregular in some contexts, but here it is used in the present tense. If strictly focusing on past tense/irregular forms, this might not apply.)

Explanation:

- Helping Verbs: These verbs assist the main verb in expressing tense, mood, or voice. They are typically found before the main verb.
- Irregular Verbs: These verbs do not follow the regular pattern of forming past tense or past participle forms. Identifying them requires knowledge of common irregular verbs.
