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，从现阶段到6月份为夯实基础阶段，在此阶段，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。

　　Astronomers announced on Monday that they had discovered what many consider the holy grail of their field: ripples in the fabric of space-time that are echoes of the massive expansion of the universe that took place just after the Big Bang.

　　词汇突破：
1. holy grail 圣杯;很常见的一个英语表达;圣杯的传说来自于基督教，传说那是耶酥基督在最后的晚餐中使用的绿柱玉琢制的酒杯，而圣约瑟(joseph of arima thea)则用它来接耶酥基督伤口流出的宝血。
　　在罗马帝国灭亡后欧洲黑暗时代的亚瑟王的传说中，寻找圣杯则成为骑士们的最高目标。Holy grail在延续千年的传说之后，常常被用来代表众人追求的目标，甚至是最高目标;比喻为伟大成就;
　　2. ripples in the fabric of space-time 时空涟漪= gravitational waves 引力波
　　引力波是由密度非常大的恒星等大品质天体运动发生的“时空涟漪”( Ripples in Space-time)。然而，即使是伟大的恒星运动发生的“时空涟漪”也非常微弱，大局部敏锐的探测器基本无奈觉察它。
　　(这一次人们发现了!!!!伟大!!!!)
