Terrence Moore reminds of an ancient but powerful truth: children emulate their parents, and this natural tendency should be capitalized upon when speaking with them. Both parents and teachers should talk up to them, rather then down to them. I would also recommend that not only should children be read to, but that they should read aloud. One way to overcome the stark fact that young people don’t hear the best in the language often enough is by having them read aloud some good literature. For the younger ones I recommend Kipling, The Elephant’s Child, for example. I defy you to read this out loud (regardless of your age) and not be smitten by the music of the language. In response to the question, "what does the crocodile have for diunner?", the Kolokolo bird says,

"Go to the banks of the great grey-green, greasy Limpopo River, all set about with fever-trees, and find out." If they are a bit older, try Jane Austen’s
Pride and Prejudice, or a couple of poems by Yeats.
