explanation: people "chat" with "language", and "english" is a "language". "podium" is a part of "classroom", which can be "attended". people can "travel" to "attractions", and the "three gorges" are "attractions". the "chef" makes "grilled fish". "bel canto" is a kind of "sing". "repertoire" refers to a script or song catalog, and "bel canto" is an opera singing method with vocal skills, and there is no obvious logical relationship between the two.
