English to Chinese:

One species of frog bases its entire mating ritual on number: If a male calls out — a whining pew followed by a brief pulsing note called a chuck — his rival responds by placing two chucks at the end of his own call. The first frog then responds with three, the other with four, and so on up to around six, when they run out of breath. 

有一种青蛙的整个交配仪式基于数字：如果一只雄青蛙发出呼叫信号——一声呜咽，然后一个简短的脉动音符，叫“咯”——他的对手以两个“咯”结束自己的呼叫。第一只青蛙回应用三个“咯”来结束呼叫，对方再次挑战用四个“咯“， 这样来来回回，直到到六个“咯”， 差不多断气为止。poor guys! :)
