问题     Researchers, writing in the journal Heart, pooled data from 23 studies and found that social isolation or feelings of loneliness were tied to an increased risk for coronary heart disease (冠心病 ) and strokes.
    The studies included data from 181,006 men and women ages 18 and over. There were 4,628 coronary events and 3,002 strokes in follow-up periods     【C1】________from three to 21 years. Three of the papers【C2】________ loneliness, 18 looked at social isolation and two included both. Social isolation and loneliness were determined with questionnaires; the researchers depended on medical records and death【C3】________for determining coronary events and strokes.
    The scientists found that loneliness and social isolation increased the     【C4】________risk of having a heart attack or a death from heart disease by 29 percent, and the risk of stroke by 32 percent. There were no【C5】________between men and women.
    "People have tended to focus from a policy point of view on【C6】________     lonely people to make them more【C7】________," said the lead author, Nicole K. Valtorta, a research fellow at the University of York in England. "Our study【C8】________that if this is a risk factor, then we should be trying to prevent the risk factor in the first place."
    The authors【C9】________that this was a review of observational studies and did not【C10】________cause and effect.

【C2】
选项
答案H
解析 空格位于主语three of the papers和名词loneliness之间，句子缺少谓语，且空格所在段落用一般过去时，因此空格处应填入动词过去式。根据下文的18 looked at social isolation and two included both“18  篇研究了社交孤立，2篇同时涵盖了这两方面”，可知空格处填入的词应与looked、included并列，表示“研究，探讨”的含义。词库中的measured“评估，判定”符合要求，故选H。
