    Names have gained increasing importance in the competitive world of higher education. As colleges struggle for market share, they are looking for names that project the image they want or reflect the changes they hope to make. Trenton State College, for example, became the College of New Jersey nine years ago when it began raising admission standards and appealing to students from throughout the state.

    “All I hear in higher education is, ‘Brand, brand, brand,’” said Tim Westerbeck, who specializes in branding and is managing director of Lippmann Hearne, a marketing firm based in Chicago that works with universities and other nonprofit organizations. “There has been a sea change over the last 10 years. Marketing used to be almost a dirty word in higher education.”

        Not all efforts at name changes are successful, of course. In 1997, the New School for Social Research became New School University to reflect its growth into a collection of eight colleges, offering a list of majors that includes psychology, music, urban studies and management. But New Yorkers continued to call it the New School.

    Now, after spending an undisclosed sum on an online survey and a marketing consultant’s creation of “naming structures”, “brand architecture” and “identity systems”, the university has come up with a new name: the New School. Beginning Monday, it will adopt new logos, banners, business cards and even new names for the individual colleges, all to include the words “the New School”.

        Changes in names generally show significant changes in how a college wants to be accepted. In changing its name from Cal State, Hayward, to Cal State, East Bay, the university hoped to project its expanding role in two mostly suburban counties east of San Francisco.

        Beaver College turned itself into Arcadia University in 2001 for several reasons: to break the connection with its past as a women’s college, to promote its growth into a full-fledged university and, officials acknowledged, to put an end to jokes about the college’s old name on late-night television and “morning zoo” radio shows.

    Many college officials said changing a name and image could produce vital results. At Arcadia, in addition to the rise in applications, the average student’s test score has increased by 60 points, Juli Roebeck, an Arcadia spokeswoman, said.

     

    51. Which of the following is NOT the reason for colleges to change their names?

    A. They prefer higher education competition.        B. They try to gain advantage in market share.

    C. They want to project their image.                    D. They hope to make some changes.

    52. It is implied that one of the most significant changes in higher education in the past decade is _________.

    A. the brand                                                      B. the college name

    C. the concept of marketing                                D. list of majors

    53. The phrase “come up with” (Line 3, Para. 4) probably means ___________.

    A. catch up with             B. deal with           C. put forward                     D. come to the realization

    54. The case of name changing from Cal State, Hayward, to Cal State，East Bay indicates that the university ___________.

    A. is observed by the society                                      B. hopes to expand its influence

    C. prefers to inform its teaching programs                   D. expects to enlarge its campus

    55. According to the officials, the name change of Beaver College ___________.

    A. turned out very successful                                     B. failed to attain its goal

    C. got rid of some jokes                                             D. transformed its status
