考研英语是一门需要长时间积累的学科，对于备战2015考研的学子们来说，同学们应该主攻单词和语法，坚持每天1-2篇的英语阅读以此来培养语感。

　　Madeleine Beekman of the University of Sydney, Australia, and her colleagues, however, have a hypothesis. As they outline in a paper in the Philosophical Transactions of the Royal Society, they think at least some of the blame lies with subcellular structures called mitochondria (pictured), which provide the body with its power by burning glucose and using the energy thus released to make ATP, a molecule that is biology’s universal fuel.

　　【词汇突破】：（以下单词不用记）
subcellular structures 亚细胞结构
　　Mitochondria 粒腺体(线粒体)
　　Glucose 葡萄糖
　　ATP　三磷酸腺苷
　　下面这个表达一定要掌握：
　　some of the blame lies with A; A 是部分原因;
　　outline 指出
　　hypothesis 假说

　　【参考译文】：但是，澳大利亚悉尼大学Madeleine Beekman同事一起提出一种假说。他们在英国皇家学会哲学学报发表的一篇论文中指出，亚细胞结构，也就是粒腺体是造成这一现象的部分原因。粒腺体通过燃烧葡萄糖为机体提供能量，并利用该能量释放三磷腺苷，三磷腺苷是生物界普遍的燃料。
