On March 14, math and science lovers around the world celebrated a special day: Pi Day.

Pi is equal to about 3.14, but the number goes on endlessly. It is sometimes written in Green π. With the help of computers, mathematicians (数学家) have been able to calculate (计算) pi out to over a trillion (万亿) decimal (小数的) places, but there is still no end to the number. This makes pi confusing, even for the most famous scientists and mathematicians.

Pi Day is celebrated around the world on March 14, since how we write this date, 3/14, looks just like the number pi.

For some people, the appeal (感染力) of Pi Day goes far beyond math and science. Pi shows up throughout popular culture. You can see it in movies, comics, music and more. “In modern movies, any time the filmmaker wants to produce a sense of mystery, often the symbol pi is used,” says David Blatner, Jewish American writer of the Joy of Pi.

People also love trying to memorize the digits (数学) of pi and competing against others to see who can remember the most. Many teachers hold class contests to see how many numbers their students can memorize. The Gummess World Record for reciting the most digits of pi is held by Li Chao of China, who successfully recited pi put to nearly 67,890 decimal places.

Above all, Pi Day is about having fun with the number. People celebrate Pi Day by eating or throwing pie and with fun pi-related games and activities. This year, Princeton, new Jersey, held a Pi Event” where people walked 3.14 miles together. Just like the number itself, the possibilities for Pi Day are truly endless.

1.From the first two paragraphs, we know that ______.

A.Pi Day is on March 15 B.the number of Pi is endless

C.it’s a day just for mathematicians D.mathematicians are able to calculate pi out

April Fool’s Day is a celebration that takes place in different countries around the world. On that day people play all kinds of tricks and jokes on each other.

One April Fool’s Day, a reporter in England announced that there would be no more spaghetti because the farmers in Italy had stopped growing spaghetti. Many people ran to their local supermarket to buy as much as spaghetti as they could. By the time people realized the story was a hoax, all of the spaghetti across the country had been sold out. In another famous trick a TV show in England reported the discovery of special water. They said it would help people lose weight and that one customer had already lost a lot of weight in just four months. By the end of the day,　more than 10000 people had phoned the TV station to find out how to get this water.

Many April Fool’s jokes may end up being not very funny. A famous TV star asked his girlfriend to marry him on his TV show. The girl said “Yes.” But he replied, “April Fool !” That joke didn’t have a very happy ending. The TV star lost his girlfriend and his show was canceled.
