问题     Any American who has bought a pack of cigarettes since the mid-’60s might have seen the health warnings. It says, "SURGEON GENERAL’S WARNING: Smoking Causes Lung Cancer, Heart Disease, And May Complicate Pregnancy." Such government warnings work,【C1】______— research has shown that smokers in countries with strong warnings know more about smoking【C2】______than those in countries where warnings are weaker. But it’s unclear whether smokers who see any warning【C3】______smoke less.
    Public-health advocates have known for years that individualized messages are far more【C4】______at getting smokers to stop. For instance,【C5】______a doctor reminds a patient that her sister has promised to help her【C6】______, that patient will be much more likely to stop smoking than someone who just sees a(n)【C7】______message on a cigarette pack.
    A recent study shows that tailored antismoking messages engage brain regions involved in how people see themselves. Those regions are associated with emotion【C8】______basic human awareness and, possibly, awareness of others’【C9】______of us.
    The authors of the study, a University of Michigan team led by psychologist Hannah Faye Chua,【C10】______91 smokers who wanted to quit. The participants, who smoked an average of 17 cigarettes per day,【C11】______medical imaging scans for one hour while different messages appeared on a screen. Some messages were tailored to their【C12】______histories (for example, "A concern you have is being tempted to smoke when【C13】______other smokers"). Some messages were general anti-smoking【C14】______.
    The researchers found that the tailored messages【C15】______the two brain regions significantly more than the non-tailored and【C16】______messages. In other words, reading a short sentence changed their brain activity—【C17】______those who showed stronger activity in those regions were more likely to quit smoking.
    The reason this paper is important is that it【C18】______a growing body of research showing that what is often mocked as "talk therapy" can produce real changes in brain【C19】______. If you really want to quit smoking, you should commit to a(n)【C20】______behavioral-therapy program. It will not only help you stop; it could change how your brain works.
【C7】

选项 A、general
B、definite
C、clear
D、obscure

答案A

解析 上文提到individualized(个性化的)信息更有用,姐姐答应帮助戒烟也是个人特色的信息.可知此处说的戒烟可能性更低的人看到的信息应该是非个性化的一般信息。故选A项general“一般性的”。
