1. Superstition 迷信
One person in four in Britain is, apparently, superstitious, and they'll do everything from hanging horseshoes over their fireplace to crossing their fingers, touching wood and absolutely never walking under a ladder. And they're careful about cats. Black cats are supposed to be the familiars of witches, so if one is following you it's definitely bad luck - a witch is after you!
On the other hand, if one crosses your path and continues then it's good luck because it hasn't noticed you. However, in some places the beliefs are different - so it pays to know where your black cat comes from!
Old superstitions linger even in today's modern world. The author Philip Pullman drew on them in his award winning novel "His Dark Materials". The novel, which appeals to both children and adults, has been adapted for radio and also the theatre.
