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.

An ice cream sundae（圣代）is a special treat that many enjoy. And in summer it is the perfect dessert to cool down with after a hot day. Of course, ice cream in any form is a dessert no child could miss either. Back in the 1890's there was an old-fashioned ice cream store in Two Rivers, Wisconsin. It was owned by a man named E.C. Berners. One day a boy named George came into the store and ordered a bowl of vanilla ice cream. He looked across the counter and noticed the bottle of chocolate syrup（糖浆）that was used in making ice cream sodas. He asked if the owner would add some to the top of his vanilla ice cream. The owner agreed and George said that it tasted really good. Other customers started to order chocolate syrup over their ice cream too. It very quickly became quite popular to do so.

But in those days ice cream cost five cents and adding the chocolate syrup made it too expensive for Berners to continue serving the ice cream that way for the same price. At last Berners came up with an idea — to sell ice cream with chocolate syrup on Sundays only.

Many years later the new name was invented by an unknown trader who thought the treat should have a name as fancy as its taste. That is how today when we enjoy ice cream with chocolate syrup it is now called a “sundae”.

根据短文内容,判断正（T）误（F）。

1.According to the passage, a sundae is in fact ice cream with chocolate syrup on it.

2.Only children liked to eat the sundae at first.

3.To save money, Berners sold ice cream with chocolate syrup on Saturdays only.

4.An unknown trader invented the name of “sundae”.

5.The passage is mainly about the history of ice-cream sundae.
