Have you ever felt like you would do just about anything to satisfy your hunger?
你有沒有想過要做些事情來滿足你的饑餓感?
A new study in mice may help to explain why hunger can feel like such a powerful motivating force.
一項在老鼠身上進行的新研究可能有助于解釋為什么饑餓感覺起來像一股強大的推動力。
In the study, researchers found that hunger outweighed other physical drives; including fear, thirst and social needs.
在這項研究中，研究人員發(fā)現(xiàn)饑餓超過了其他身體驅(qū)動力；包括恐懼、口渴和社會需求。
To determine which feeling won out, the researchers did a series of experiments.
為了確定哪種感覺勝出，研究人員做了一系列實驗。
In one experiment, the mice were both hungry and thirsty.
在一個實驗中，老鼠們又餓又渴。
When given the choice of either eating food or drinking water, the mice went for the food, the researchers found.
研究人員發(fā)現(xiàn)，當讓老鼠選擇吃東西還是喝水時，它們會選擇食物。
However, when the mice were well-fed but thirsty, they opted to drink, according to the study.
然而，根據(jù)這項研究，當老鼠吃得很飽但是很渴的時候，它們會選擇喝水。
In the second experiment meant to pit the mice's hunger against their fear, hungry mice were placed in a cage that had certain "fox-scented" areas and other places that smelled safer (in other words, not like an animal that could eat them) but also had food.
在第二個實驗中，饑餓的老鼠被放在一個籠子里，籠子里有一些“狐貍氣味”區(qū)域和其他氣味更安全的地方(換句話說，不像能吃它們的動物)，但也有食物。
It turned out that, when the mice were hungry, they ventured into the unsafe areas for food.
事實證明，當老鼠餓了的時候，它們會冒險進入不安全的區(qū)域覓食。
But when the mice were well-fed, they stayed in areas of the cage that were considered "safe."
但當老鼠吃得很飽時，它們會呆在籠子里被認為“安全”的地方。
Hunger also outweighed the mice's social needs, the researchers found.
研究人員發(fā)現(xiàn)，饑餓也超過了老鼠的社會需求。
Mice are usually social animals and prefer to be in the company of other mice, according to the study.
根據(jù)這項研究，老鼠通常是群居動物，喜歡和其他老鼠在一起。
When the mice were hungry, they opted to leave the company of other mice to go get food.
當老鼠餓了的時候，它們選擇離開其他老鼠的同伴去找食物。
