花董的题出得真是太有水平了。发现翻译歌词做到押韵真难。是一荷唱的吧？

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. 

有一种青蛙的交配仪式完全基于数字：如果一只雄蛙鸣叫---一声长鸣跟着一种短促的音符---他的竞争对手在长鸣之后报之以两声短鸣。 第一只青蛙然后回应三声，另一只回应四声，以此类推，直到六声，直到他们用尽了气息。

宁愿相信我们前世有约
今生的爱情故事 不会再改变
宁愿用这一生等你发现
我一直在你身旁 从未走远
只是因为在人群中 多看了你一眼

I would rather believe we promised in the past life

The love story  of this life ain't break away

I would rather wait for you to approach my life

I've been standing by you，never go away

It's due to the sight upon you when you arrive

Idioms：

Conversation:

B:你在逗我吗？它乏味无聊至极。
