A4纸是生活中最常用的纸规格．A系列的纸张规格特色在于：①A0、A1、A2…、A5，所有尺寸的纸张长宽比都相同．②在A系列纸中，前一个序号的纸张以两条长边中点连线为折线对折裁剪分开后，可以得到两张后面序号大小的纸，比如1张A0纸对裁后可以得到2张A1纸，1张A1纸对裁可以得到2张A2纸，依此类推．这是因为A系列纸张的长宽比为：1这一特殊比例，所以具备这种特性．已知A0纸规格为84.1厘米×118.9厘米.118.9÷84.1≈1.41≈，那么A4纸的长度为（ ）A.厘米 BSusan Sontag（1933—2004） was one of the most noticeable figures in the world of literature. For more than 40 years she made it morally necessary to know everything—to read every book worth reading, to see every movie worth seeing. When she was still in her early 30s，publishing essays in such important magazines as Partisan Review，she appeared as the symbol of American culture life，trying hard to follow every new development in literature，film and art. With great effort and serious judgment，Sontag walked at the latest edges of world culture.　　Seriousness was one of Sontag’s lifelong watchwords（格言），but at a time when the barriers between the well-educated and the poor-educated were obvious, she argued for a true openness to the pleasure of pop culture. In “Notes Camp”, the 1964 essay that first made her name，she explained what was then a little—known set of difficult understandings，through which she could not have been more famous.“Notes on Camp”，she wrote，represents “a victory of ‘form’ over ‘content’, ‘beauty’ over ‘morals’ ”.By conviction（信念）she was a sensualist（感觉论者），but by nature she was a moralist（伦理学者），and in the works she published in the 1970s and 1980s，it was the latter side of her that came forward. In “Illness as Metaphor”—published in 1978，after she suffered cancer—she argued against the idea that cancer was somehow a special problem of repressed personalities（被压抑的性格），a concept that effectively blamed the victim for the disease. In fact，re-examining old positions was her lifelong habit.In America，her story of a 19th century Polish actress who set up a perfect society in California，won the National Book Award in 2000. But it was as a tireless，all-purpose cultural view that she made her lasting fame.“Sometimes,” she once said，“I feel that，in the end，all I am really defending…is the idea of seriousness，of true seriousness.”And in the end，she made us take it seriously too.64．The underlined sentence in paragraph l means Sontag ____________.A．was a symbol of American cultural life B．developed world literature，film and artC．published many essays about world culture D．kept pace with the newest development of world culture 65．She first won her name through____________.A．her story of a Polish actress B．her book Illness as MetaphorC．publishing essays in magazines like Partisan Review D．her explanation of a set of difficult understandings 66．Susan Sontag’s lasting fame was made upon____________.A．a tireless，all-purpose cultural view B．her lifelong watchword: seriousnessC．publishing books on morals D．enjoying books worth reading and movies worth seeing 67．From the works Susan published in the 1970s and 1980s，we can learn that _____.
