把这一句，留给此刻的你
The basic structure of proteins is quite simple: they are formed by hooking together in a chain discrete subunits called amino acids.
蛋白质的基本结构很简单:它们是由一个称为氨基酸的链的离散亚基连接在一起形成的。
A LITTLE ENCOURAGEMENT
给此刻的你，一点向前的力量。
关于学习、善意与成长，读一句，再想一想。
Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young. The greatest thing in life is to keep your mind young.
任何停止学习的人都是老的，不管是二十岁还是八十岁。任何不断学习的人都会保持年轻。生命中最伟大的事情是保持你的头脑年轻。
A competent and self-confident person is incapable of jealousy in anything. Jealousy is invariably a symptom of neurotic insecurity.
一个能干而自信的人是不会妒忌任何事情的。嫉妒总是一种神经质的不安全感的症状。
The writer who loses his self-doubt, who gives way as he grows old to a sudden euphoria, to prolixity, should stop writing immediately: the time has come for him to lay aside his pen.
如果一个作家失去了自我怀疑，随着年龄的增长，他突然变得兴高采烈，变得啰嗦，那么他应该立即停止写作:他该放下笔了。
