研究发现表明，经常观看电视里大量反对吸烟广告，而且能够精确描述出广告含义的年轻人与其他同龄人相比，吸烟的可能性更小。
What''s more, their likelihood of remaining nonsmokers appears to increase with the number of television ads they view and are able to correctly describe.
而且，他们观看的反对吸烟的广告越多和广告含义描述的越准确，不吸烟的人数就有可能越多。
The findings are based on telephone responses from 12- to 20-year-olds involved in a follow-up survey 20 months after the April 2001 start of the Florida "truth" anti-tobacco media campaign.
这项研究从2001年4月佛罗里达州的"真相"--反对吸烟媒体运动而开始，历时20个月，主要为电话反馈调查，对象是12岁到20岁之间的年轻人。
This campaign included 11 television ads that aimed to prevent youth from starting smoking by informing them about strategies used by the tobacco industry to popularize smoking.
这场反烟媒体运动包括了11个电视广告，旨在通过揭露烟草生产商为了吸引人们吸烟而采用的(广告等)计谋，从而阻止年轻人开始吸烟。
Those who were able to describe, in detail, at least one of the 11 ads were 23% more likely to remain nonsmokers at follow-up. The almost 40% of youth who were able to accurately describe four or more ads were 68% more likely to remain nonsmokers, the report indicates.
调查表明，那些至少能说出11个广告中的1个的年轻人就有23%的可能以后不吸烟。而40%以上的年轻人能够说出4个或者更多的反烟广告，他们今后不吸烟的可能性为68%。
In contrast, young people who were unable to accurately describe any of the television ads were more likely to say that the campaign theme did not influence their smoking in any way.
相对的，那些连1个反烟广告都记不清楚的年轻人很可能会说，这个反烟运动无论如何都不会阻止他们吸烟的。
