The romantic love story of toads
蟾蜍：我很丑，但是我很温柔
Toads are often perceived as an ugly species who dress in a filthy ,dark-colored and dirt-like skin which are full of pimples . Worse still, toads can emit poisonous mucus which makes people avoid them like plague .however, ugly-shaped toads can have colorful love lives.
蟾蜍通常被认为是一种丑陋的物种，它们穿着肮脏的、深色的、像污垢一样的皮肤，身上长满了疙瘩。更糟糕的是，蟾蜍会发出有毒的粘液，使人们像躲避瘟疫一样躲避它们。然而，丑陋的蟾蜍也有丰富多彩的爱情生活。
One day, one a male toad was facing the water pond and bulging an air sac which is bigger than its head---it was coo-cooing . It turns out the male toad is summoning a female toad with his love song.
有一天，一只雄性蟾蜍面对水塘，鼓起一个比它的头还大的气囊---它在咕咕叫着。原来，这只雄蟾蜍正在用它的情歌召唤一只雌蟾蜍。
Generally, the closet female toad would follow the sound to find the male toad after hearing the love song. Strangely, when the male and female toads get married, they will spend honeymoon of nearly 3 weeks with an empty stomach.
一般来说，隐藏在附近的雌蟾蜍听到情歌后，会循声找到雄蟾蜍。奇怪的是，当雄蟾和雌蟾结婚时，它们会空腹度过近三周的蜜月。
