trees.All of this was the result of the warm winter in southern Switzerland.Soon hundreds of people called into the television station wanting to find out how they could grow their own spaghetti tree.

　　In 1962，there was only one television channel (频道) in Sweden，and it broadcast in black and white.On the first day of April，the station broadcast that a new technology had been created，which would make it possible to see color pictures on their black and white television sets.It said that all people needed to do was pull a nylon stocking (尼龙袜) over the screen.It also suggested moving one's head very carefully back and forth to best experience the picture.Many people got excited，and thousands tried it.

　　There was another such news program on April 1，1975.On the program that evening it said that Australia would be changing to "metric time"．It was explained that under metric time，there would be 100 seconds in a minute，100 minutes in an hour，and 20 hours in a day.It was also explained that seconds would become millidays，minutes would become centidays，and hours would become decidays.The report had many details，including an interview with South Australia's deputy premier (副总理) and a picture of Adelaide's town hall clock，with its new 10­hour metric clock face.In the end，many people fell for the news.

　　Are these news reports believable？Of course not.So the next time you hear something that sounds too silly to be true，look at your calendar (日历) and make sure that it isn't April first!
