Dip the spoon into the soup, moving it away from the body, until it is about two-thirds full, then sip the liquid (without slurping) from the side of the spoon (without inserting the whole bowl of the spoon into the mouth).

An exchange student is a student (almost always of high school age) who temporarily goes abroad and lives with a host family in a foreign country, and attend school there. That host family often also sends a child of theirs abroad, usually to the same country as the student they are hosting. In this way, the two students are said to have been "exchanged," essentially temporarily trading countries with each other.
