Passage One

Have you ever felt like you would do just about anything to satisfy your hunger? A new study in mice may help to explain why hunger can feel like such a powerful motivating force. In the study, researchers found that hunger outweighed other physical drives, including fear, thirst and social needs.

To determine which feeling won out, the researchers did a series of experiments. In one experiment, the mice were both hungry and thirsty. When given the choice of either eating food or drinking water, the mice went for the food, the researchers found. However, when the mice were well-fed but thirsty, they opted to drink, according to the study. 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. It turned out that, when the mice were hungry, they ventured into the unsafe areas for food. But when the mice were well-fed, they stayed in areas of the cage that were considered "safe." Hunger also outweighed the mice's social needs, the researchers found. Mice are usually social animals and prefer to be in the company of other mice, according to the study. When the mice were hungry, they opted to leave the company of other mice to go get food.

Questions 16 to 18 are based on the passage you have just heard.

16. What is the researchers’ purpose in carrying out the serious experiment with mice?

17. In what circumstances, do mice venture into unsafe areas?

18. What is said about mice at the end of the passage?

【听力翻译】

你有没有想过要做些事情来满足你的饥饿感?

一项在老鼠身上进行的新研究可能有助于解释为什么饥饿感觉起来像一股强大的推动力。

在这项研究中，研究人员发现饥饿超过了其他身体驱动力；包括恐惧、口渴和社会需求。

为了确定哪种感觉胜出，研究人员做了一系列实验。

在一个实验中，老鼠们又饿又渴。

研究人员发现，当让老鼠选择吃东西还是喝水时，它们会选择食物。

然而，根据这项研究，当老鼠吃得很饱但是很渴的时候，它们会选择喝水。

在第二个实验中，饥饿的老鼠被放在一个笼子里，笼子里有一些“狐狸气味”区域和其他气味更安全的地方(换句话说，不像能吃它们的动物)，但也有食物。

事实证明，当老鼠饿了的时候，它们会冒险进入不安全的区域觅食。

但当老鼠吃得很饱时，它们会呆在笼子里被认为“安全”的地方。

研究人员发现，饥饿也超过了老鼠的社会需求。

根据这项研究，老鼠通常是群居动物，喜欢和其他老鼠在一起。

当老鼠饿了的时候，它们选择离开其他老鼠的同伴去找食物。

请根据你刚刚听到的文章回答问题16至问题18。

问题16：研究人员在小鼠身上进行这一系列实验的目的是什么？

问题17：在什么情况下，小鼠会冒险进入不安全的区域？

问题18：关于文章结尾的老鼠是怎么说的？
