睡莲叶子

Where the willow meets the water, a frog was sitting on a lily pad.

在柳枝轻拂水面的地方，一只青蛙正蹲在睡莲叶子上。

Once upon a time there lived a young frog who often sat upon a very soft lily pad.

从前有只小青蛙，经常坐在一片极柔软的睡莲叶子上。

There are fewer frogs than lily pad.

青蛙比睡莲叶子多。

The difficult part of this "lily pad problem" is that people tend to assume that, if lily pads need 29 days to spread over half of the pond, it would probably take them a few more days to blanket the other half, while the terrible end will in fact come the day after.

"睡莲叶子问题"使人不解的地方使人们趋向于这样设想：如果睡莲叶子蔓延29天才超过池子的一半面积，那么覆盖其另一半可能需要更多的时间。然而，实际上，可怕的结果在第二天就来临了。

For this reason I would like to borrow the examples of the "lily pad problem" that once troubled France and the "horse manure public hazard" that some British scholars warned people of during the Industrial Revolution.

因此，我想借用曾经困扰整个法兰西的"睡莲叶子问题"和在工业革命期间，某些英国学者警告人们的"马粪公害"的例子来做讲解。

A frog's heaven, no doubt. Miasma, scum, pond lilies, stagnant water. Sit on a lily pad unmolested and croak all day. Something like that, I imagine.

无疑这是一个青蛙的天堂，瘴气、泡沫、睡莲和不流动的水，坐在一片没有人烦扰的睡莲叶子上呱呱叫上一整天—我设想天堂大概就是这样的。

Lily pads float in a reflecting pool in the Missouri Botanical Garden.

浮在水面上的睡莲叶子飘流在一个倒影池位于密苏里植物园。

On bright, calm days they lie in thousands on the now darkening water, mostly yellow flotillas of poplar, floating continuously down from great trees that themselves shake in the windless air with the sound of falling water , but on rainy days or after rain they seem to swim or be driven away, and nothing remains to break the surface except the last of the olive-yellow lily pads that in high summer covered every inch of water like plates of emerald porcelain...

当风和日丽时，无数的树叶浮在已经变暗的湖水上，大部份都是白桦叶子，他们一批一批，像黄色的小小扁舟，不断地从高高的树上飘落下来，在无风的空气中轻轻地晃动着，发出如同流水而下的声音。但是在下雨的时候，或者雨过之后，那些浮在湖面上的落叶，仿佛鱼儿一样都游走了，又像是被不知什么驱赶一空，湖面上除了最后的几片黄绿色睡莲叶子，再无一物，而在盛夏里，那些睡莲叶子，如同翠绿晶莹的瓷盘，覆盖着每一寸湖面。

On bright calm days they lie in thousands on the now darkening water mostly yellow flotillas of poplar floating continuously down from great trees that themselves shake in the windless air with the sound of falling water but on rainy days or after rain they seem to swim or be driven away and nothing remains to break the surface except the last of the olive- yellow lily pads that in high summer covered every inch of water like plates of emerald porcelain.

在风和日丽的日子里，白杨树叶伴着水流的节奏簌簌地落下，像一叶叶黄色的扁舟，成千上万地泊在这秋水中。在下育的日子里或育后时节，它们或游离此地，或随波逐流。平静的湖面上只剩下残存的黄绿色的睡莲叶子。而盛夏时，睡莲叶子宛如葱绿晶莹的瓷盘，覆盖着湖面的每寸水域。睡莲凋零了。

In this manner, the negative charge hops downward from leader to leader like a frog jumping from lily pad to lily pad across a pond.

而负电荷就是以这样的先导区至先导区的方式，如同青蛙从一朵睡莲叶子跳至另一朵睡莲叶子越过池塘，到达地面。
