跨学科·数学 Did you hear of Pi Day? You may think it is all about having pies. That's only partly right. Pi Day is actually about maths! Every year on March 14th, maths lovers celebrate Pi Day to honor(纪念) the special number pi. Zu Chongzhi worked out that "pi" is a number between 3.1415926 and 3.1415927. It is about 3.14, but the number goes on endlessly. It is sometimes written as "π" in Greek.
We can write March 14th as 3/14. It looks just like the number pi. So people around the world celebrate Pi Day on March 14th.
Pi Day is about having fun with the number. People celebrate Pi Day by having pies and having activities about maths. On this day, class usually begins with π. Students try to remember as many digits(数位) of pi as they can. Then they will eat a piece or two pieces of delicious pie! Restaurants have pies at a special price for the day. You can buy a pizza for just 3.14.
How did Pi Day start? Interestingly, scientist Albert Einstein was also born on March 14th. In 1988, an American scientist thought that people should remember this day. Then the holiday was born. In 2009, the US made Pi Day a holiday.
Maybe you like maths. Maybe you don't. But Pi Day is a good chance to learn something new, and maybe eat some pies, too.

【解题导语】本文介绍了π日(国际圆周率日)的来历,以及人们如何庆祝它。
文化背景
国际圆周率日,即国际数学日,是庆祝圆周率π的特别日子,正式日期是3月14日,由圆周率最常用的近似值3.14而来。该节日通常是在下午1时59分开始庆祝,以象征圆周率的六位近似值3.14159。
1 D 写作手法题。根据文章首句“Did you hear of Pi Day?”可知,作者是通过提问题的方式展开的,故选 D。
2 A 细节理解题。根据第一段中的“Every year on March 14th, maths lovers celebrate Pi Day to honor(纪念) the special number pi”可知,数学爱好者最有可能会对π日感兴趣。故选 A。
3 C 段落大意题。

解题通法
快速定位段落主旨句
段落的组织形式不同,其主旨句的位置也有所不同。一般来说,有以下四种类型:
(1)“开门见山”型,即在段落首句提出主旨,后文运用解释或举例说明等方法展开;
(2)“段末点睛”型,即细节表述在前,归纳概括在后,在段尾出现主旨句;
(3)“段中主旨”型,即段首先描述细节,段中归纳主旨,继而做出进一步解释;
(4)“无明确主旨”型,同学们需要根据关键词和段落内容概括出段落大意,这种情况下可多关注重复出现的词。
