The symbols of Easter :Easter bunny(兔子)
The Hare and the Rabbit were the most fertile animals known and they served as symbols of the new life during the Spring season.

The customs of Easter: Egg hunt
The custom of an Easter egg hunt began because children believed that hares laid eggs in the grass. The Romans believed that "All life comes from an egg." Christians consider eggs to be "the seed of life" and so they are symbolic of the resurrection of Jesus Christ
 

　　复活节是基督教纪念耶稣复活的一个宗教节日。每年，春分过去，第一次月圆后的第一个星期日就是复活节。日期年年不同，一般在3月22日至4月25日之间。今年是4月16日。

　　复活节有不少传统习惯，最典型的要数复活节彩蛋。古人常把蛋视为多子多孙和复活的象征。后来基督教徒又赋予蛋新的涵义，认为它是耶稣墓的象征，未来的生命就是从其中挣脱而出世的。复活节时人们把鸡蛋染成红色，代表耶稣受难时流出的鲜血，同时也象征复活后的快乐。还有一种古老的习俗，是把煮熟的鸡蛋送给街头的孩子们做游戏，他们把蛋往前滚，谁的蛋最后破，谁就获得胜利，蛋全归他所有。

　　兔子也是复活节的象征。因为兔子繁殖力很强，所以人们把它视为新生命的表现者。大人常绘声绘色地告诉孩子复活节彩蛋是兔子下的，并把彩蛋放在花园里，让孩子们玩找蛋游戏。

　　现在每逢复活节，美国大小糖果店总要出售用巧克力制成的复活节小兔和彩蛋。这些彩蛋小的和鸡蛋差不多，大的竟有甜瓜那么大，孩子们自然喜欢，送给亲戚朋友，也不失为上佳礼品。
