其实我很想问D为什么不对,D取非后不是Researchers have determined whether the metabolic rates of formerly very overweight individuals can be accelerated by means of chemical agents.
也就是说研究者已经确定了胖下来的瘦子的新陈代谢率可以通过化学药剂来增加,所以说削弱了结论:胖子会重新胖起来。。。
求解释。。。
consume calories=摄入卡路里
burn calories=消耗卡路里
例句详见CNN:Is drinking soda really that bad for you?一文中
Men consume on average 178 calories per day from sugar sweetened beverages and women consume 103 calories per day.
