Nothing, anything...

I gave the children (something / anything / nothing) to eat because they were very hungry.

She doesn't want (someone / anyone / no one) to help her.

Ouch! I've got (something / anything / nothing) in my eye.

I don't know (something / anything / nothing) about it.

The fridge is empty. There isn't (something / anything / nothing) there.

She put (something / anything / nothing) in the box. But I don't know what it was...

I don't know (someone / anyone / no one) here. It's my first day at work.

Calm down. There is (something / anything / nothing) to worry about.

The room looks empty. Is there (someone / anyone / no one) here?

The fridge is empty. There's (something / anything / nothing) there.

(Someone / Anyone / No one) lives in that house. It's empty.

I think there isn't (someone / anyone / no one) in the room.
