A first chapter has to hook you, and there's lots of different ways to do it. A Spy Like Me, by Laura Pauling, hooks with humor - it's the funniest first chapter I think I've ever read.
The first two pages hook with the setting and character. Saavy is an American teenager in Paris, on a date with a cute French waiter. He asks her to close her eyes as he sets her up for a surprise.
