问题 Time for another global-competitiveness alert. In the Third International Mathematics and Science Study—which last year tested a half-million students in 41 countries—American eighth graders【C1】______below the world average in math. And that’s not even【C2】______part. Consider this as you try to【C3】______which countries will dominate the technology markets of the 21st century: the top 10 percent of America’s math students scored about the same as the average kid in the global【C4】______, Singapore.
It isn’t exactly a news flash these days【C5】______Americans score behind the curve on international tests. But educators say this study is【C6】______because it monitored variables both inside and outside the classroom. Laziness—the factor often【C7】______for Americans’ poor performance—is not the culprit here. American students【C8】______spend more time in class than pupils in Japan and Germany. 【C9】______, they get more homework and watch the same amount of TV. The problem, educators say, is not the kids but a curriculum that is too【C10】______. The study found that lessons for U. S. eighth graders contained topics mastered by seventh graders in other countries.
Teachers actually agree that Americans need to【C11】______their kids to more sophisticated math earlier. Unfortunately, experts say, the teachers don’t recognize that【C12】______these concepts are taught is as important as the concepts themselves. Most educators rely【C13】______on textbooks and rote learning (死记硬背). While many textbooks cover【C14】______ideas, most do so superficially,【C15】______students with the techniques but not the mastery of the broader principles. [br] 【C1】

选项 A、recorded
B、gained
C、climbed
D、scored

答案 D

解析句子前半部分的意思：在去年举行的第三次国际数学和科技研究中对41个国家的50万学生进行了测试。空格所在部分大意是：美国八年级学生的数学——低于世界平均分。分析各个选项，选出符合文意的项。record“记录；录下”；gain“获得，到达，增加，获利，(钟、表等)走得快”；climb“攀登，爬，上升”；score“得分”。根据文意可知是数学得分低于世界平均分。D项符合文意。因此本题选D。
