解析 词义辨析【直击答案】空格所在句意为“同样的，一定程度上超重，经常是健康的”。根据前面的文章内容，已经明确指出超重代表了健康，因此超重是健康的指标。因此正确答案为A项。【命题思路】本题考查对上下文语义的正确把握。【干扰排除】干扰性强的是B项，有考生会将其理解为“客观物质”，但原文结构中此处需要一个名词，objective“客观的”是形容词，objective作名词时意为“目标”，另有考生被形近词objection“反对”干扰。Of even greater 5 is the fact that obesity turns out to be very difficult to define.It is often defined 6 body mass index,or BMI.BMI__7__body mass divided by the square of height.An adult with a BMI of 18 to 25 is often considered to be normal weight.Between 25 and 30 is overweight.And over 30 is considered obese.Obesity,__8,can be divided into moderately obese,severely obese,and very severely obese.【译文】需要更加关注是，很难对肥胖加以定义。肥胖经常根据身体质量指数来定义，或叫做BMI，它等于身体重量除以身高平方。正常成年人的是BMI值应该在18～25之间。25～30的话视为超重。30以上视为肥胖。肥胖依次能够分为中度肥胖、重度肥胖和极度肥胖。
