问题 Optimism is good for the heart, a study said on Monday.
The must optimistic among a group of 545 Dutch men aged 64 to 84 had a【B1】50 percent lower risk of cardiovascular(心血管的)death over 15 years of follow-up,【B2】to the study published in the Archives of Internal Medicine.
【B3】research has suggested being optimistic【B4】overall physical health and lowers【B5】risk of death from all causes. A【B6】attitude also has been shown to help patients who suffer【B7】heart disease caused by narrowed arteries(动脉).
The new study measured【B8】level of optimism about their lives by having them【B9】to statements such as "I do not look forward to【B10】lies ahead for me in the years to come" and "My days seem to be passing by slowly," or "I am still【B11】of plans." "Optimism can be【B12】easily and is stable over long periods,【B13】it does tend to decrease with age," said lead researcher Erik Giltay of the Institute of Mental Health in Deft, the Netherlands.
On a【B14】of zero to three, with three being most optimistic, the【B15】scores in the study【B16】from 1.5 in 1985 to 1.3 in 2060.
Higher scores were【B17】with being younger, being better【B18】, living with others, having better health, and doing more【B19】activity.
"It is yet to be established whether interventions aimed【B20】improving an older individual’s’ level of optimism may reduce the risk of cardiovascular mortality," he added.
选项 A、hardly
B、more
C、roughly
D、or so
答案B
解析 根据空白处上下文所示，此处需要一个副词来修饰数字。文中可以看出，这里对心态最乐观的人是肯定的态度。[A]表明“几乎不到50％”，与原文表达的含义矛盾。[C]需要添加than才可以。[D]通常修饰数字，放在后面，表示“大约”。只有[B]符合原文含义并可以放在数字之前，表示“大约，大概”的意思。此句意为“经过15年的随访，在64岁至84岁的545名荷兰人中，心态最乐观的人因心血管疾病而死亡的几率比其他人低50％左右。”
