问题     As if they needed any more excuse, new research suggests men need their sleep if they’re to live a long life. Women, on the other hand, can live long lives【C1】________poor sleep habits as long as they eat a diverse diet that includes vitamin B6 and plenty of vegetables. Vitamin B6 can be found in food such as meat, bananas and nuts.【C2】________other things, it allows the body to use and【C3】________energy from protein and carbohydrates.
    The findings come from a study led by Professor Mark Wahlqyist from Monash University which looked at how diet【C4】________sleep quality and mortality among elderly men and women. Professor Wahlqvist said sleep played a more【C5】________role in men’s mortality than women’s. "Poor sleep has been associated with increased disease rate and mortality.

【C5】

选项 A、active
B、leading
C、important
D、dual

答案C

解析 文章第一句提到男性要想长寿,就得有充足的睡眠,可见睡眠的重要性,因此空格处应能体现出睡眠的重要性。C项important“重要的”语义符合。A项active“积极的,活跃的”,为褒义词,与mortality(死亡率)语义矛盾。B项leading“领导的,主要的”,是与“次要的”相对而言,不符合此处语境。D项dual“双重的”,无从得知睡眠是否起到双重作用。
