问题     For decades, Americans have taken for granted the United States’ leadership position in the
development of new technologies. The innovations (创新)that resulted from research and development during World War II and afterwards were【C1】______to the prosperity of the nation in the second half of the 20th century. Those innovations, upon which virtually all aspects of【C2】______society now depend, were possible because the United States then【C3】______the world in mathematics and science education. Today, however, despite increasing demand for workers with strong skills in mathematics and science, the【C4】______of degrees awarded in science, math, and engineering are decreasing.
    The decline in degree production in what are called the STEM disciplines (science, technology, engineering, and math)seems to be【C5】______related to the comparatively weak performance by US schoolchildren on international assessments of math and science. Many students entering college have weak skills in mathematics. According to the 2005 report of the Business-Higher Education Forum, 22 percent of college freshmen must take remedial (补习的)math【C6】______, and less than half of the students who plan to major in science or engineering【C7】______complete a major in those fields.
    The result has been a decrease in the number of American college graduates who have the skills,【C8】______in mathematics, to power a workforce that can keep the country at the forefront (前沿)of innovation and maintain its standard of living. With the【C9】______performance of American students in math and science has come increased competition from students from other countries that have strongly supported education in these areas. Many more students earn【C10】______in the STEM disciplines in developing countries than in the United States.
A)accelerating I)especially
B)actually J)future
C)closely K)led
D)contemporary L)met
E)courses M)procedures
F)critical N)proportions
G)declining O)spheres
H)degrees [br] 【C4】

选项

答案 N

解析 空格处前面是定冠词the,后面是of degrees限定成分,故该词应为名词。前句句意为“虽然对于那些在数学和科学方面技能超强的人才的需求持续增加”,是让步状语从句,那么后句所说的事实应该是学位的减少,故选择proportions“比例”。备选的名词中,degrees与后文重复,首先排除;courses意为“课程”,procedures意为“过程”,spheres意为“球体”,均与上下文文意无关,故排除。
