April Fools' Day: 愚人节，直译“四月傻瓜日”
“Fool me once, shame on you. Fool me twice,shame on me”: 骗我一次，是你不对；
But fool me three times, it must be AprilFool's Day: 上三次当，原来今天是愚人节
April 1 In sixteenth-century France, the start of the new year was observed onApril first. It was celebrated in much the same way as it is today with partiesand dancing into the late hours of the night. Then in 1562, Pope Gregoryintroduced a new calendar for theChristian world, and the new year fell onJanuary first. There were some people, however, who hadn't heard or didn't believethe change in the date, so they continued to celebrate New Year's Day on Aprilfirst. Others played tricks on them and called them April fools. In Francetoday, April first is called Poisson d'Avril. French children fool theirfriends by taping a paper fish to their friends' backs. When the young fooldiscovers this trick, the prankster yells Poisson d'Avril!
Today Americans play small tricks onfriends and strangers alike on the first of April. One common trick on AprilFool's Day, or All Fool's Day, is pointing down to a friend's shoe and saying,Your shoelace is untied. School children might tell a classmate that school hasbeen canceled. Whatever the trick, if the innocent victim falls for the joketheprankster yells, April Fool!
Most April Fool jokes are in good fun andnot meant to harm anyone. The most clever April Fool joke is the one whereeveryone laughs, especially the person upon whom the joke is played. Americanhumorist Mark Twain has said that the first of April is the day we rememberwhat we are the other 364 days of the year.
