The answer explains verb usage in sentence structure, including forming negative sentences and utilizing contractions for informal speech.
Explanation:
Verbs:
To create the negative form of a sentence, we use the auxiliary verb 'do' or 'be' with 'not.' For example: 'I haven't got a telescope.'
In sentences like 'I was earlier, but I'm not now,' the verb 'was' is used in the past tense to indicate the previous state, while 'am' is used in the present tense to show the current state.
Using contractions such as 'they're,' 'isn't,' and 'wouldn't' helps in informal speech to combine pronouns, verbs, and negations efficiently.
