三、阅读理解

Do you know about a special number that helps us learn about circles (圆)? It's called Pi, and it's a number that never ends. Pi starts with 3.14, but it goes on and on with more numbers we can't see.
A long time ago, a smart man from China named Zu Chongzhi found a way to figure out Pi.
He studied some cool math and discovered (发现) that Pi is about 3.1415926. Amazingly, Zu Chongzhi's finding about Pi had been right for over 800 years! Knowing this number is like having a magic key to understanding circles better.
People all around the world celebrate Pi on March 14th. They do this because the date looks like the first three numbers of Pi: 3 - 1 - 4. On this day, people do fun math activities and learn more about circles. Students in the US usually eat pie and throw pie at each other. Fukuoka High School in Japan celebrates Pi Day with pi memorization games. They try to remember as many numbers of Pi as they can. It shows their memory skills.
The celebration of Pi Day starts a culture about Pi. It also makes people enjoy math through all kinds of celebrations.
Now, let's look at some interesting ways in which Pi helps us in daily life:
Making a Beautiful Circle: If you want to draw a circle with a diameter (直径) of 8 cms, you can use Pi to know how long to draw the circle. Just multiply (乘) 8 by Pi (about 3.14), and you'll get how long the circle is.
Measuring Wheels(测量车轮): If you have a bike, Pi helps you find out how far it goes with one full turn of its wheel. Just measure the wheel's diameter and multiply by Pi.
