填空题 During the past two decades, dozens of investigators throughout the world have asked several hundred thousand 1 sampled people to reflect on their happiness and satisfaction with life or what psychologists call "subjective wellbeing." (represent)

【正确答案】

【答案解析】representative[解析] 句意：在过去的20年间，全世界许多调查人员向上万名有代表性的人员询问了他们对生活的满意度，也就是心理学家所称的“主观幸福感”。这里讲到抽样调查的样本应当是具有典型性的，因此此处应当填representative，意为“有代表性的，典型的”。
