When you want to give information to a person you can use a declarative sentence. For example, "Joan and Núria are work mates and they are talking about their other collegues".
Nuria has found out that Marina, her boss, lives in Barcelona and she tells this to Joan.
Núria: La Marina viu a Barcelona.
Listen again to the sentence you have just listened to.
Listen to the melody of the sentence; in the last word of the sentence the voice falls gradually, until the end.
Now imagine that Marina does not live in Barcelona, but she lives in Sabadell. Listen and watch the example.
Now, pronounce the sentence with the same declarative intonation. Imagine that you are talking with a friend. You are talking about your work mates and you say to him La "Marina viu a prop del Carrer Major". After saying it, listen how it is pronounced.
Listen to these sentences and decide whether the intonation is the same as the sentence you heard in the initial video.
Listen to these sentences and say whether the intonation is appropriate for the context.
