问题     Secondhand smoke is accountable for 42,000 deaths annually to nonsmokers in the United States, including nearly 900 infants, according to a new study. Altogether, annual deaths from secondhand smoke【C1】______nearly 600,000 years of potential life lost—an average of 14.2 years per person—and $6.6 billion in lost productivity,【C2】______to $158,000 per death, report the researchers. The new research reveals that despite public health efforts to reduce tobacco use, secondhand smoke continues to【C3】______a grievous toll on nonsmokers.
    "In general, fewer people are smoking and many have made lifestyle changes, but our research shows that the impacts of secondhand smoke are【C4】______very large," said lead author Wendy Max, PhD, professor of health economics at the University of California. "The【C5】______of information on biomarker-measured(生 物指标测量)exposure allows us to more accurately assess the impact of secondhand smoke exposure on health and productivity. The impact is particularly great for communities of color."
    Exposure to secondhand smoke is linked to a number of【C6】______illnesses including heart and lung disease, as well as conditions affecting newborns such as low birth weight and respiratory distress syndrome. In the research, the scientists【C7】______the economic implications—years of potential life lost and the value of lost productivity—on different racial and ethnic groups.
    "Our study probably underestimates the true economic impact of secondhand smoke on【C8】______," said Max. "The toll is substantial, with communities of color having the greatest【C9】______. Interventions need to be designed to reduce the health and economic burden of smoking on smokers and nonsmokers alike, and on particularly【C10】______groups."
A)losses B)turbulent C)nonetheless D)availability
E)adhering F)generalized G)take H)triumphs
I)fatal J)henceforth K)mortality L)represent

【C1】
选项
答案L
解析 空格前的名词中心词是annual deaths，空格后是名词600,000 years，故需填人谓语动词，时态与上一句的is一样是一般现在时。因此是原形。本句说明二手烟的危害，句意为：每年二手烟引起的死亡……差不多60万年的潜在寿命损失。空格后是对二手烟引起的损失的具体说明，故填入represent“代表，表示”逻辑合理。take后也可接时间，表示“花费”，常用于it takes sb．to do sth．结构。
