【答案解析】[听力原文] There are many superstitions in Britain, but one of the most widely held is that it is unlucky to walk under a ladder even if it means stepping off the pavement into a busy street. If you must pass under a ladder you can avoid bad luck by crossing your fingers and keeping them crossed until you have seen a dog. Alternatively, you may lick your finger and make a cross on the toe of your shoe, and not look again at the shoe until the mark has dried. Another common superstition is that it is unlucky to open an umbrella in the house. It will either bring misfortune to the person who opened it or to the whole household. Anyone opening an umbrella in fine weather is unpopular, as it inevitably brings rain. The number 13 is said to be unlucky for some, and when the 13th day of the month falls on a Friday, anyone wishing to avoid a bad event had better stay indoors. The worst misfortune that can happen to a person is caused by breaking a mirror, as it brings seven years of bad luck. The superstition is supposed to have originated in ancient times, when mirrors were considered to be tools of the gods. Black cats are generally considered lucky in Britain, even though they are associated with witchcraft. It is especially lucky if a black cat crosses your path although in America the exact opposite belief prevails. Finally, a commonly held superstition is that of touching wood for luck. This measure is most often taken if you think you have said something that is taking a risk, such as 'my car has never broken down, touch wood' How to avoid bad luck when you must pass under a ladder in Britain? 听力原文中提到If you must pass under a ladder you can avoid bad luck by crossing your fingers and keeping them crossed until you have seen a dog. 由此可知，如果必须通过梯子底部，可以让手指保持交叉状态，直到看到狗时再放开，这样就可以避免厄运。故选项D为答案。
