水桥
巴拿马运河把大西洋与太平洋之间的航行联系起来，人们有时把它比作一座让船通过的“水桥”。

The Panama Canal links travel between the Atlantic and Pacific, sometimes described as a “water bridge” for ships.
这座“桥”并不是把河水架在空中，而是让船沿着安排好的航道，通过不同水位之间的船闸。

A ship approached the lock while staff on shore guided it into the chamber.
船停稳以后，船尾的门合上。四周暂时安静下来，船仍浮在水里，等待水位改变。

The ship enters the chamber, the gate closes behind it, and entering water raises both the water level and the ship.
等闸室与前方水位相合，前面的门才打开，船驶出去，进入下一段航道；如果要降低，则进行相应的排水过程。
děng zhá shì yǔ qián fāng shuǐ wèi xiāng hé， qián miàn de mén cái dǎ kāi， chuán shǐ chū qu， jìn rù xià yí duàn háng dào； rú guǒ yào jiàng dī， zé jìn xíng xiāng yìng de pái shuǐ guò chéng。
When levels match, the forward gate opens; lowering instead uses a corresponding draining process.
不同阶段不能随意颠倒，闸门、水位与船的位置相互配合，才使整个过程能够按顺序完成。

宽大的船慢慢驶离闸室，岸边的设施静静留在身后，远远看去平缓的航行，背后却有许多协调的步骤。

A large ship slowly leaves the chamber; its calm passage depends on many coordinated steps behind the scenes.
“水桥”的比喻因此多了一层意思：它连接的不只是两边的位置，也是水位、工程与航行的关系。
“shuǐ qiáo” de bǐ yù yīn cǐ duō le yì céng yì si： tā lián jiē de bù zhǐ shì liǎng biān de wèi zhì， yě shì shuǐ wèi、 gōng chéng yǔ háng xíng de guān xì。
