问题     If you’re one of those people who tends to put on weight around your middle, what doctors call an "apple shape"—what the rest of us call a beer belly—you’ve probably been told that you’re at higher risk of heart disease. But one large new review study suggests you shouldn’t be too【C1】________after all.
    It turns out that the apple-shaped among us are not at any higher risk of heart trouble as people with pear shapes or any other kind of fat【C2】________. In the latest study, researchers at the Emerging Risk Factors Collaboration in the UK reviewed records of more than 220000 participants in 58 different trials that followed【C3】________for more than 10 years for heart-related events. They found that body shape, or fat distribution, did not seem to affect heart disease risk.
    In fact, the researchers write in the journal Lancet, various measures of obesity, including body mass index (or BMI, a combined measure of height and weight), waist circumference (周长) and waist-to-hip ratio, all had about the same【C4】________value in identifying increased risk of a heart attack. What’s more, 【C5】________to the forecasting power of known risk factors such as high cholesterol, high blood pressure and a history of diabetes, the obesity measures added very little to the【C6】________of risk assessment.
    Previous studies had focused not just on overweight, but on the type and【C7】________of fat deposits as a red flag for heart disease. The thinking was that even without blood tests for cholesterol or blood pressure, body shape alone could alert doctors and patients to the fact that patients might be at higher risk of heart problems. One headline-grabbing survey reported a three-fold【C8】________risk in heart disease among those with abdominal fat—folks with apple-shaped bodies—and speculated that visceral (内脏的) fat, which tends to【C9】________around the middle, is particularly hazardous for the heart, since it nestles deep within organs and can pump out hormones that【C10】________insulin (胰岛素) sensitivity and promote diabetes.
    A) accumulate   F) decreased       K) elevating
    B) accuracy     G) discouraged     L) increased
    C) alter        H) distinguished   M) location
    D) compared     I) distribution    N) predictive
    E) conflicted   J) diversion       O) volunteers [br] 【C6】
选项
答案 B
解析 名词辨析题。分析句子结构可知，of risk assessment应作空格所填词的后置定语，因此空格处应填入一个名词。此处句意为：和已知的风险因素，如高胆固醇、高血压和糖尿病史的预测能力相比，肥胖衡量标准并不能提高心脏病风险评估的________。结合备选名词可知，B项accuracy “准确性”符合题意。
