April 1st is an unofficial holiday in the United States called April Fool's day. In the past, April 1st used to be celebrated as the New Year. And then in the year, I think, 1592, or something like that, the official New Year was changed to January 1st and some people never heard of this change so they continued to celebrate the New Year on the April 1st, but the people who knew of this change called them fools. A fool in English is someone who is not smart. We have many words for this in English: dumb, a dummy, stupid, imbecile, idiot, but you're all nice people so you'll never need to use those words so you can forget that. But the people who continued to celebrate the New Year's on April 1st were called April fools. So a tradition started, that on April 1st people would try to make, would do pranks on other people.
4月1日是美國(guó)的一個(gè)非正式節(jié)日,稱(chēng)作愚人節(jié)。過(guò)去,4月1日曾經(jīng)被當(dāng)作新年來(lái)慶祝。我想大概是在1592年,新年正式更改為1月1日,可是有些人并沒(méi)有聽(tīng)到更改的消息,所以他們繼續(xù)在4月1日慶祝新年,而知道更改日子的民眾便稱(chēng)那些人是愚人。英語(yǔ)中說(shuō)的愚人就是那些不聰明的人。英語(yǔ)中有很多詞來(lái)形容這個(gè)意思:愚蠢的,笨蛋,笨的,蠢貨,白癡,但是你們都是善良的人,所以你們永遠(yuǎn)不需要使用這些詞,所以你可以不去管那些。但是繼續(xù)在4月1日慶祝新年的人被稱(chēng)作四月愚人。所以這就是這個(gè)節(jié)日傳統(tǒng)的由來(lái),在4月1日,人們會(huì)對(duì)其他人做惡作劇。
