    A considerable amount of medical research is aimed at identifying risk factors for disease. The rationale 【C1】be______this work is that where people are informed of their risk, they will happily change their behavior to 【C2】low______that risk. Although this is certainly a reasonable assumption, it turns 【C3】______that things are not quite that simple and straightforward. First of all, health is not necessarily a top priority in everyone’ s life and, for these people, changing behavior in the interest of health may interfere 【C4】______other, more important matters. Second, the benefits to be derived from such 【C5】ch______rarely are immediate or obvious. Usually, improvements in health take place over long periods of time and are quite subtle. 【C6】______, we are all so bombarded with information about the thousands of health hazards to which we are exposed to most of us " tune out" much of this information. This latter issue is compounded by the 【C7】fac______that much of new information to which we are exposed through the media is exaggerated and, as often as not, is contradicted later by even "newer" information. For these and other reasons, simply knowing about a risk does not necessarily ensure that people 【C8】______(take) appropriate steps to change it.
    Even when people want to change their 【C9】______, this is not easy to do. For example, the overwhelming majority of smokers in this country want to quit, but make great effort very few are able to do so. Most smokers 【C10】______(acknowledge) at some level, that health hazards associated with smoking and most wish that there were a simple and painless way to stop. And the number of people who want to lose weight is very large, but few of these people are able to do it and even none are able to maintain such weight losses.
【C9】
选项
答案behavior
解析 该句的意思是“即使人们想要改变他们的行为，这也是不容易的”。空白处前面讨论“改变行为”这件事情，空白处前面有change一词，空白处考虑填入behavior。故填入behavior。
