For this case we can translate the paragraph as:
Today is a boring day. Does not occur __________. I'm in the park, but I can't talk to _________ because my friends aren't here.
______________ birds are here but I don't want to talk to them! I don't have _________ homework to do. I dont have a book to read _________. I want to do something but I do not know what. I write in my diary, but I don't have ______________ interesting to say, so ... bye!
Then we must fill in the blanks with the appropriate word.
The day is boring because nothing significant happens. So the correct sentence is: "No ocurre nada"
As the friends are not in the park then he has no one to talk to, the correct sentence is: "...pero no puedo hablar con nadie..."
He says there are birds in the park, then: "Algunos pájaros estan..."
He says he has no homework to do, then: "No tengo ninguna tarea..."
Similarly, he does not have a book either, so: "No tengo un libro para leer tampoco..."
He says he doesn't know what to do, then: "Quiero hacer algo..."
He also thinks he doesn't have something interesting to say in the newspaper, then: "Pero no tengo nada interesante..."
Answer:
The words are:
Nada
