[不定项选择题]共用题干 Stanford University

1 Stanford University,famous as one of northern California's several institutions of higher
learning,is sometimes called"the Harvard of the West."The closeness of Stanford to San
Francisco,a city thirty-two miles to the north,gives the university a decidedly cosmopolitan
（世界性的）flavor.
2 The students are enrolled mainly from the western United States.But most of the fifty
states send students to Stanford,and many foreign students study here,as well.And
standards for admission remain high.Young men and women are selected to enter the
university from the upper fifteen per cent of their high school classes.
3 Not only because of the high caliber（素质）of its students but also because of the
desirable location and climate,Stanford has attracted to its faculty some of the world's most
respected scholars.The university staff has included many Nobel prize winners such as
Dr.Felix Bloch,Dr.Robert Hofstadter,and Dr.William Shockley in physics,Dr.Author
Kornberg and Dr.Joshua Lederberg in medicine,and Dr.Paul J.Flory and Dr.Linus Pauling
in chemistry.The Russian novelist Aleksandr Solzhenistsyn has been in residence.
Stanford's undergraduate school of engineering and its graduate schools of business,law,
and medicine are especially well-regarded.
4 What is student life like on"The Farm"?Culturally,the campus is a magnet for both
students and citizens of nearby communities.Plays,concerts,and operas are performed
in the university's several auditoriums and in its outdoor theater,where graduations are also
held.Several film series are presented during the school year.Guest lecturers from public
and academic life frequently appear on campus.In the evenings,many students gather to
socialize in the Student Union's coffee house ; here the beverages（饮料）and the
atmosphere both have a decidedly European flavor.For the sports-minded,the Stanford
campus offers highly developed athletic facilities.Team sports,swimming,and track and
field activity are all very much part of the Stanford picture.So are bicycling and jogging.
5 In addition to financial support from alumni（校友）,Stanford receives grants from the
government and from private philanthropic（慈善的）foundations.In recent years,
government grants have made possible advanced studies in the fields of history,
psychology,education,and atomic energy.At present Stanford is carrying out an
ambitious building program,financed in part by the Ford Foundation's 25 million grant.
