       3. Noun (or pronoun) + infinitive with "to"
       4. When a noun (or pronoun) is followed by an infinitive with "to", it is similar to a relative clause. 
          For example, 'I have a lot of work to do' means the same as "I have a lot of work that I must do'. The sentence "There is nothing in the fridge for us to eat" means "There is nothing in the fridge that we can eat".
