When you take something apart to understand it, of course you can never quite put it back together again the same way and see it holistically. But there's no other way to gain a good understanding of the component parts, so this is a worthwhile exercise, even if they don't enjoy it in the same way as other reading.

I'd contend very few teenagers are really ready to enjoy Sense and Sensibility or similar texts anyway because of their different and short experience of life, but they are in a position to learn some of the techniques and vocabulary used.
