Optimists outlive pessimists, a new study shows. Of nearly 100,000 women【C1】______in the Women's Health Initiative, those who gave【C2】______answers on a personality test were 9% less likely to【C3】______heart disease within eight years—and 14% less likely to【C4】______—than women who got low optimism【C5】______on the test. TIME's Alice Park wrote about an earlier【C6】______of this study in the spring. She writes: 【C7】______studies have indeed documented the life-extending benefits of optimism,【C8】______most of that research has involved only men and has been【C9】______in small numbers. What's more, not all studies have done a good job of【C10】______out potentially confusing factors such as health【C11】______and lifestyle. That's【C12】______makes the new study different "Taking into【C13】______income, education, health behaviors like blood pressure and whether or not you are【C14】______active, whether or not you drink or smoke, we still see optimists with a decreased risk of death compared to pessimists," says Dr. Hilary Tindle, lead author of the study. "I was surprised that the relationship was【C15】______of all of these factors." The study also found an interesting and【C16】______disturbing difference in the way that attitude is related to【C17】______for black women vs. white women. Pessimistic black women in the study were 33% more likely to have died after eight years than optimistic black women, while white pessimists were only 13% more likely to have died than their optimistic【C18】______The numbers in the study weren't large enough to support any【C19】______explanations for this racial gap, but "there is definitely a suggestion that whites and blacks may be【C20】______in how optimism affects longevity," says Tindle.

【C2】
【正确答案】
C
【答案解析】解析：全文谈论的是optimists和pessimists，由than可知句子是对两者进行比较，比较的另一方是women who got low optimism…，表示悲观的妇女，则空格的内容应指乐观回答的妇女，故选C项optimistic“乐观的”。
【答案解析】解析：本题宜用排除法解答。空格充当的是表语从句makes the new study different的主语，故排除连接副词D项where。A项which“哪一个”需要指出“选择范围”，而原文并没有提及“选择范围”，故也排除。此处谈论的是因素而非人，故排除B项who。所以选C项what。

【答案解析】解析：由空格前的blood pressure和后面的whether or not you drink or smoke可知这里主要是谈论身体状况，故选A项physically“身体上”最为合适。
【答案解析】解析：由空格后的but可知前后分句存在转折关系，but后用了there is definitely a suggestion(这至少明确说明)，可推断空格所在句表示不能“明确说明”。D项definitive“确切的”代入文中，表示“研究涉及的人数不够广，还不足以为这一种族差距提供确切的解释”，符合要求。
