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] 【C9】

选项

答案 G

解析 该空格前为定冠词the,后面为名词performance,故应该填入名词的修饰成分,可能是形容词或现在分词。根据上下文可知,美国学生在数学和科学方面的表现应该是逐渐变差的,故现在分词declining符合该句句意。备选项中,形容词里没有表示“变差”含义的词。现在分词中accelerating表示“加速”,与句意不符。故排除。
