Explanation:
Before answering our exercises we need to understand to what we refer when we talk about impersonal constructions.
We talk about impersonal constructions when the sentence that we produce doesn’t have a determined subject; this implies that we don’t have a “responsible” for the action that is expressed by the conjugated verb.
One way of producing impersonal sentences is by adding the syntactical particle “SE” instead of a substantive. For example:
Now we have our answers:
1. En Costa Rica SE HABLA español
2. En las librerías SE VENDEN libros y revistas
3. En los restaurantes SE SIRVE comida
4. En los consultorios SE RECETA medicina
5. En el campo SE VIVE muy bien.
Notice how we don’t have a specified subject in any of these sentences and, related to their meaning, all of them can be understood as GENERALITIES or things that occur constantly.
