NEGATIVE SENTENCES

1. We have not been to Paris.
Explanation: "have been" is the present perfect tense of the verb "to be" and it is used to express actions that started in the past and continue into the present. To make a negative sentence in the present perfect tense, we use "have not" or "haven't" before the past participle of the main verb, which in this case is "been".

2. She has not seen 'The Lord of the Rings'.
Explanation: Similar to the previous sentence, we use "has not" or "hasn't" before the past participle of the main verb "seen" to make a negative sentence in the present perfect tense.

3. He has not met my mother.
Explanation: Once again, we use "has not" or "hasn't" before the past participle verb "met" to create a negative sentence in the present perfect tense.
