每日一句：Some three billion years ago, when Earth was a sprightly ocean world dotted with protocontinents and inhabited solely by single-celled organisms, a pair of black holes spiraled together and collided in a far-off region of the universe, leaving behind a single black hole some 50 times heavier than our sun.

参考译文：约30亿年前，在宇宙的一个遥远的区域，两个黑洞相互盘旋和碰撞，留下了一个比我们的太阳重50倍的黑洞。那时的地球还是一片充满活力的海洋世界，其中点缀着若干原始大陆，单细胞生物是唯一的居民。

原文章讲的是黑洞和引力波

每日一句：These rates may not curb smoking much, because tobacco companies, which are sometimes monopolies, can cut their profit margins on cheaper brands and raise them on luxury ones to offset their losses.

每日一句：Scientists at the Scripps Institute in La Jolla, Calif., reported Thursday that the accumulation of several mutations in the main gene on the virus’s surface may be able to give H7N9 the ability to spread like human flu viruses do, passing from person to person through coughing and sneezing.

参考译文：斯克瑞普斯研究所（位于加州拉荷亚）的科学家周四报告说，病毒表面的主基因出现的多种变异积累后有可能令H7N9有能力像人类流感病毒一样，在人与人之间通过咳嗽和打喷嚏传播。

每日一句： Sometimes, you just can't have what you want, but it does not mean you can never have it. Everything takes place at the right time.
