Here is the news from VOA.
Researchers studying a no-smoking law in the western U.S. state of Colorado says that the law in one city led to a 40 percent decrease in the number of people suffering from heart attacks. Dr. Terry, who is in charge of the project, says the study shows that secondhand smoke may be an under-recognized cause of heart attack deaths.
"For too long we have considered passive smoking, which is secondhand smoking in restaurants, bars, and other public places as common and usual. However, these numbers tell us that even in a short time secondhand smoke can produce rapid changes in the working of the heart, and cause heart attacks. We found there were 499 patients for heart attacks in the city in the 18 months before the law took effect. After the no-smoking law was passed, only 205 were sent to the hospital for heart attacks in the same time period."
答案解析:
(1)正确答案为A。根据Researchers studying a no-smoking law 研究禁烟法的研究人员,因此可知,这篇新闻讲的是禁烟法,因此A项正确。
(2)正确答案为B。根据the law in one city led to a 40 percent decrease in the number of people suffering from heart attacks. 该法案使一个城市心脏病患者的数量下降了40%。可知,这项法律减少了心脏病患者的人数,因此对公众有益,B项正确。
(3)正确答案为C。根据We found there were 499 patients for heart attacks in the city in the 18 months before the law took effect. 在这项法律生效前的18个月,该城市有499名心脏病患者。可知,在法律通过的18个月前,有499名,即近500名心脏病患者,因此C项正确。
