摘　　要：大家每年都会在3月14日庆祝圆周率日。为什么?因为这个日期正是圆周率的前三个数字,也就是3.14。圆周率it是数学里一个特别的数字,能够帮助我们算出圆形的面积和周长。圆周率符号TT的发音听起来像是“派”,所以大家都会在那天通过吃派来庆祝圆周率日。有些学校和数学爱好者也会举办有趣的活动,例如尽可能多记圆周率数值的位数。这是一个充满乐趣的日子,能够让人享受数学,当然还可以吃派!People celebrate National Pi Day on March 14th every year.Why?Because the date matches the first three digits of Pi,which is 3.14.Pi is a special number in math that helps us find the area and circumference of circles.Pi sounds like Pie.So on National Pi Day,people celebrate by eating pie.Some schools and math lovers also do fun activities,such as trying to remember as many digits of Pi as possible.It's a fun day to enjoy math and,of course,eat pie!
