IV. Further reading

Read the passage and answer the questions.

    Pi Day is celebrated on March 14. Math enthusiasts(爱好者) know all about it, and the rest of the population is probably hoping for cherry pie.

    Pi Day started 28 years ago at San Francisco’s Exploratorium(探索博物馆). Physicist Larry Shaw, who worked in the electronics group at the museum, started celebrating pi on March 14, 1988, primarily with museum staffers. The tradition has grown to embrace(信奉) math enthusiasts from all walks of life.

    This year, the Exploratorium is hosting a day-long celebration at its facility on Pier 15, including a Pi Procession(背诵), pi “exportable”(探索) and servings of pie.

Pi Day is also Albert Einstein’s birthday. In Princeton, New Jersey, where Einstein lived for more than two decades, signs of the scientist permeate the Pi Day festivities, which span five days

The tradition has grown to embrace(信奉) math enthusiasts from all walks of life.

参考答案

II. 1. B。根据“Using a supercomputer, they calculated (计算) pi to 62.8 trillion (万亿) digits. ”可以得知,π的位数被计算到62.8万亿位,是一个更加深远的计算。

2. C

3. 人们一直在努力尽可能准确的计算圆周率。

4. D。从四千年前发现圆周率,到中国数学家祖冲之计算到3.1415927,再到伊朗数学家Al-Kashi,计算到小数点后16位,本段在讲述圆周率的研究历史。所以选D

5. Because it’s widely used in our lives.

6. D“World records are not useful by themselves, but they set a benchmark (基准) and they teach us about what we can achieve.”

世界纪录本身是无用的,但是它们设置了一个基准,让我们了解我们能达成什么样的成就。所以是有意义的。选D

7. B。从第六段首句可知,圆周率应用于生活中的方方面面。“I can’t imagine any real-life use where you would need any more than 15 decimal places,”可以排除C。同时这一句也是迷惑句,有的同学看到这句可能会选D,但是本句并不是表示Harvey否定精确计算pi值的价值。

8. People eat pie and recite the value of pi.

III. 1. make efforts to 2. compare to 3. broke a new record 4. too much 5. pop up

IV. 1. On March 14.

2. 这个传统在各行各业数学爱好者们传开。

3. They have a Pi Procession, pi "exportable" and servings of pie.
