Is it common to ask questions in English by means of intonation alone? For instance the following line from a webpage confuses me:
Since Hindi does not have the auxiliary do, learners are prone to asking questions by means of intonation alone: She has a brother?

The obvious way to ask this question is "Does she have a brother?". But to me sentences like "You live here?" or "You went shopping?" sound very natural.
