    We all know that emotions originate in the brain. But we usually talk about our emotions coming from our hearts. If someone you know doesn’t give up 【C1】______, you might say, "He’s got a lot of heart." Then what about bad emotions? When you feel so sad that your heart "aches," could it actually be true? A new study shows what goes on in your mind can, literally, break your heart.
    In the study, just published in the Journal of the American College of Cardiology, researchers looking at more than 63,000 women who were participants in the 【C2】______ Nurses’ Health Study, found that, those who reported basic symptoms of depression had a higher-than-normal 【C3】______ of heart attack. And women who were clinically depressed were more than twice as likely 【C4】______ other women to suffer sudden heart attack. None of the participants had heart problems at the study’s 【C5】______, but nearly 8% had symptoms of depression.
    The researchers theorize that depression might have some direct physiological impact on the heart-like 【C6】______ it to work harder in the face of stress. Or it may be that the antidepressants (抗抑郁药) 【C7】______ to treat those with mood problems were associated with heart diseases; in the study, sudden heart attack was linked more 【C8】______ with antidepressant use than with women’s symptoms of depression.
    No one is sure exactly how depression hurts the heart, and one 【C9】______ explanation is that a damaged heart and its consequent stress on the body might activate, somehow, genes or other physiological changes that 【C10】______ depression.
【C6】
选项
答案I
解析 上文提到抑郁有可能对心脏产生直接的生理影响，由此判断like…为具体举例，因此like为介词，空格处需要填入名词或动名词，且填入的词应与have some impact on呼应，causing符合句子语境，此处意思是“导致心脏在面对压力时运作更困难一些”。make词形不对，应予以排除。
