1. I warned James to stay at the hotel near the airport.
To determine the correct preposition, we need to consider the verb "warned" and the context of the sentence. In this case, we are warning someone about something, so the correct preposition is "to." Additionally, to form the correct verb form, we need to use the base form of the verb "stay" without any changes.

2. We congratulated them on getting a special grant to encourage their research.
To express congratulations for achieving something, we use the preposition "on" followed by the verb "get" in the -ing form ("getting").

3. There's nothing to stop him from achieving his aim.
To indicate the absence of an obstacle or barrier, we use the preposition "from" followed by the verb "achieve" in the -ing form ("achieving").

4. The teacher accused the boy of paying little attention to what she was saying.
To attribute an action or behavior to someone, we use the preposition "of" followed by the verb "pay" in the -ing form ("paying"). This construction indicates that the boy is accused of not paying attention.

5. The police are doing everything to prevent the criminal from leaving the country.
To indicate preventing someone from doing something, we use the preposition "from" followed by the verb "leave" in the -ing form ("leaving").

6. Forgive me for interrupting you, but I must ask you a question.
To express forgiveness for an action, we use the preposition "for" followed by the verb "interrupt" in the -ing form ("interrupting"). This construction indicates that the speaker is seeking pardon for their interruption.

7. I can't excuse you for breaking your promise, Nick.
To express inability to forgive or pardon an action, we use the preposition "for" followed by the verb "break" in the -ing form ("breaking"). This construction indicates that the speaker cannot excuse or forgive Nick's action of breaking the promise.
