     There are different superstitions (迷信) in different countries. In Britain, for example, many people do

not like to walk under a ladder or to open an umbrella in a house. If they spill(撒) salt, they will often

throw some of it over one of their shoulders.

     When people marry, their friends often tie old shoes to the back of the wedding car. This is because

the shoes can kick away bad spirits(幽灵). Another wedding superstition is to throw small pieces of

paper over the couple. This paper is called confetti(五彩纸屑) . Some people believe that throwing

confetti over the couple will help them to have many children. At one time people wanted to have many

children, but nowadays people usually want only one or two children. However, we still throw confetti

over the couple!
