Answer: escuchaba.....sonó
Yo escuchaba la música cuando el teléfono sonó.
I listened to music when the phone rang.
Explanation: "escuchaba" is conjugated in the imperfect, as something in process without defining if it was completed and the verb "sonó" is conjugated in the preterite as a completed action that interrupts the action that was in process.
To replace the accompanying noun, write a <u>direct object</u>. They can be replaced if it is masculine it is "lo" (singular) or "los" (plural) and if it is feminine it is "la" (singular) or "las" (plural).
The <u>indirect object</u> replaces the one who receives the verb. It can be replaced, if it is in the third person, "le" (singular) or "les" (plural); they can also be replaced by unstressed pronouns (me, se, te, nos, os).
When a direct object and an indirect object are joined, <u>the indirect object must be put first and then the direct object</u>. When a third person indirect object is added, put "se".
