问题     The United States’ predominance in science and technology is fading, a report released this month by the National Science Board warns. The report underlines what a powerhouse the United States【C1】______in knowledge- and technology-intensive industries, including high-tech manufacturing, energy and drug industry. All in all, those industries【C2】______for about 40 percent of American economic output, more than in any other developed country, it finds.
    But with the rise of increasingly【C3】______emerging economies, the report suggests, underinvestment in research and development might translate into a less【C4】______, less productive American economy in the future.
    The world is【C5】______a "dramatic shift in the global scientific: landscape," said Dan E. Arvizu, chairman of the National Science Board.

    The Asian economies now perform a larger【C8】______of global research and development than the United States does. China carries out about as much high-tech manufacturing as the United States does, the report found.
    But the report also highlights some important market sectors where the United States appears to be falling behind. More【C9】______, the report finds that the United States might be【C10】______in the research and development spending that scientists say is the most important fuel for future innovation. Moreover, many countries spend larger and faster-growing proportions of their economic output on research.
A) account E) directly I) limited M) share
B) competitive F) dominant J) priority N) undergoing
C) concern G) effect K) remains O) worryingly
D) decays H) lagging L) role
【C9】
选项
答案O
解析 该空位于句首，与主句部分以逗号相隔，故推测填副词。空前的More提示，此句内容是上一句的递进，前句提到报告强调美国在某些重要的市场领域里似乎已落后其他国家，该句含消极意味，故对应地此处应选择表消极意义的副词worryingly“更令人担忧的”。
