问题     The prospects for women who are scientists and engineers at major research universities have improved, although women continue to face inequalities in salary and【C1】______to some other resources, a panel of the National Research Council concludes in a new report.
    In recent years "men and women【C2】______in science, engineering and mathematics have enjoyed【C3】______opportunities," the panel said in its report. It found that women who【C4】______university jobs and, once they have them, for【C5】______and tenure(任期), are at least as【C6】______to succeed as men. But compared with their numbers【C7】______new PhD.’s, women are still less than men in applicant pools, a【C8】______that offers an opportunity for further research, the panel said.
    In【C9】______report, researchers at the University of Wisconsin reviewed a variety of studies and concluded that the【C10】______gap between boys and girls in mathematics performance had【C11】______to the vanishing point.
    "U.S. girls have now【C12】______equality with boys, even in high school and even for measures【C13】______complex problem solving," the Wisconsin researchers said. 【C14】______girls are still relatively scarce in the ranks of young math prodigies(神童), they said, that gap is narrowing, which【C15】______claims that a greater prevalence of【C16】______mathematical talent in males is【C17】______determined. The researchers said this and other phenomena "provide abundant【C18】______for the impact of sociocultural and other environmental【C19】______on the development of mathematical skills and talent and the size,【C20】______any, of math gender gaps."

选项 A、undertakes
B、underlines
C、understands
D、undermines

答案D

解析 考查动词辨义。undertake“承担”;underline“强调”;understand“理解”;undermine“破坏;削弱”。此空前面的the gap is narrowing和后面的“生理特性决定男性更有数学天分这种观点”是相违背的,说明此处填入的谓语动词应该是不支持这种claims“观点,论断”,因此选择undermines,而不是underlines。undermines此处延伸为“推翻……观点”的意思。undertakes和understands的主语一般是人,故排除。
