How can you tell when a fish wants to eat Does a hungry fish look the same as a full one
Dr.Smith trained (训练) her angel Fish (神仙鱼) to ring a bell when they wanted food.For a few days she didn't feed (give food to ) them at all.They were very hungry.Then she tied a little bell to one end of a string (绳子).She tied food to the other end and put it in the water.When the fish ate,the bell rang.
This went on for a few days.The fish ate the food,and the bell rang.Then Dr.Smith put the string into the water without food.The fish bit (咬) at the empty string and the bell rang.Every time they did this,Dr.Smith gave them food.Soon the fish had learned to pull the string and ring the bell when they were hungry.Have you ever seen fish with their own dinner bell

你如何判断一只鱼什么时候想要进食?一条饥饿的鱼看起来就和一条吃饱的鱼没什么了两样.
斯密斯博士训练了她的神仙鱼通过摇想铃铛来获取食物.在一段时间里,她没有喂任何东西给鱼.鱼变得非常饿.然后,她用一个绳子的一端拴住一个小铃铛,另一端系上食物并把它放到水里,当鱼开始吃时,铃铛就响起.
这样持续了一段时间,鱼吃食则铃铛响.然后斯密斯博士把 一根没有食物的绳子放入水中,鱼开始咬绳子使铃铛响起.每次他们这么做的时候斯密斯博士就喂给他们食物.不久,鱼就学会在饿的时候通过摇动绳子来弄响铃铛.你曾经看到过鱼有它们自己的进餐铃铛么?
