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] 【C7】

选项

答案 B

解析 该空格前面为句子主语部分,后面为谓语动词complete,故所填词应该为副词。根据上文所述,美国大学新生数学不好,同时,计划学习科学或工程类专业的学生不到一半能够完成专业学习。选择actually起到强调作用,符合句意。备选的副词中,especially强调特殊性,closely表示紧密的关系,均不符合该句句意,且closely已经选过,故排除。
