问题     If you think life is wonderful and expect it to stay that way, then you may have a good chance of living to a ripe old age, at least that is what the findings of a new study suggest. That study found that participants who reported the highest levels of optimism were far more likely to live to age 85 or【C1】________. This was compared to those participants who reported the lowest levels of optimism. It is【C2】________that the findings held even after the researchers considered factors that could【C3】________the link, including whether participants had health conditions such as heart disease or cancer, or whether they experienced depression. The results add to a growing body of evidence that certain psychological factors may predict a longer life【C4】________. For example, previous studies have found that more optimistic people have a lower risk of developing chronic diseases, and a lower risk of【C5】________death. However, the new study appears to be the first to【C6】________look at the relationship between optimism and longevity. The researchers【C7】________that the link found in the new study was not as strong when they factored in the effects of certain health behaviors, including exercise levels, sleep habits and diet. This suggests that these behaviors may, at least in part, explain the link. In other words, optimism may【C8】________good habits that bolster health. It is also important to note that the study found only a【C9】________. as researchers did not prove for certain that optimism leads to a longer life. However, if the findings are true, they suggest that optimism could serve as a psychological【C10】________that promotes health and a longer life.

选项
答案O
解析 空格前是不定冠词a和形容词psychological，空格后是that引导的从句，由此可知，空格处应填入一个单数可数名词。整篇文章介绍了乐观心态和长寿之间的关系，而上文提及，这项研究只发现了一种相关性，因为研究人员并没有明确证明乐观会使人长寿。由此推断，此处是说，“然而，如果这些发现是正确的，它们表明乐观可以成为一种促进健康和长寿的心理特征”。根据常识可知，乐观是一种心理特征，trait符合语境，故本题应选O。
