红河哈尼梯田是以哈尼族为主的各族人民利用当地“一山分四季，十里不同天”的地理气候条件创造的农耕文明奇观，据载已有1300多年的历史。请看本报昨日的报道：

Refined through trial and error over more than a millennium, the rice terraces are an inspiring example of an entire community working symbiotically with nature, with land use arranged by elevation into distinct ecological zones. Rainfall and moisture from dense mountain fog are collected in forested catchment areas high on the slopes, recharging ground water; spring water is channeled to irrigate the terraces; pooled water evaporates to form clouds; and clouds gather to shed rain on the high forests. The hydrologic cycle then repeats ad infinitum.

报道中的ad infinitum源自拉丁语，即to infinity (无休无止的)。例如：

Nowadays, the mooncake has become the Christmas fruitcake of China, passed around and regifted ad infinitum.

而现在月饼更像是圣诞节的水果蛋糕，被当作礼物送来送去。
