蒂姆库克传_英译序言_1

Each time a man stands up for an ideal, or acts to improve the lot of others, or strikes out against injustice, he sends forth a tiny ripple of hope, and crossing each other from a million different centers of energy and daring, those ripples build a current that can sweep down the mightiest walls of oppression and resistance.
-Robert F. Kennedy

每当有人为理想而奋不顾身，或为改善他人的境况而奋斗不息，或为对抗不公而勇往直前时，他都从百万个不同的角落发出了一丝希望的涟漪。这些充满能量和胆量的涟漪彼此激荡，最终汇聚成一股强大的洪流，足以冲垮一切压迫与阻力的围墙。

【Vocabulary·ripples】

A ripple is a small wave on the surface of something, such as a ripple that forms a ring around the spot where you threw a pebble into the pond.

Ripple can also be a verb. For example, you might see raindrops ripple on top of a puddle. Ripple was first used in the 1670s to describe something that causes a ruffled surface, sort of like how water seems to momentarily gain texture as it's stirred. Ripple later came to describe a very small wave, but you've probably heard of the "ripple effect" in which tiny waves spread, setting off more and more waves.
