歷年英語(yǔ)四級(jí)聽(tīng)力真題短文15

Have you ever felt like you would do just aboutanything to satisfy your hunger?

你有沒(méi)有想過(guò)要做些事情來(lái)滿足你的饑餓感?

A new study in mice may help to explain why hungercan feel like such a powerful motivating force.

一項(xiàng)在老鼠身上進(jìn)行的新研究可能有助于解釋為什么饑餓感覺(jué)起來(lái)像一股強(qiáng)大的推動(dòng)力。

In the study, researchers found that hungeroutweighed other physical drives; including fear, thirst and social needs.

在這項(xiàng)研究中，研究人員發(fā)現(xiàn)饑餓超過(guò)了其他身體驅(qū)動(dòng)力;包括恐懼、口渴和社會(huì)需求。

To determine which feeling won out, the researchers did a series of experiments.

為了確定哪種感覺(jué)勝出，研究人員做了一系列實(shí)驗(yàn)。

In one experiment, the mice were both hungry and thirsty.

在一個(gè)實(shí)驗(yàn)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, theresearchers found.

研究人員發(fā)現(xiàn)，當(dāng)讓老鼠選擇吃東西還是喝水時(shí)，它們會(huì)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(xiàng)研究，當(dāng)老鼠吃得很飽但是很渴的時(shí)候，它們會(huì)選擇喝水。

In the second experiment meant to pit the mice's hunger against their fear, hungry mice wereplaced in a cage that had certain" fox-scented" areas and other places that smelled safer (inother words, not like an animal that could eat them) but also had food.

在第二個(gè)實(shí)驗(yàn)中，饑餓的老鼠被放在一個(gè)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(shuō)，不像能吃它們的動(dòng)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(shí)證明，當(dāng)老鼠餓了的時(shí)候，它們會(huì)冒險(xiǎn)進(jìn)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(dāng)老鼠吃得很飽時(shí)，它們會(huì)呆在籠子里被認(rèn)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(guò)了老鼠的社會(huì)需求。

Mice are usually social animals and prefer to be in the company of other mice, according to thestudy.

根據(jù)這項(xiàng)研究，老鼠通常是群居動(dòng)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(dāng)老鼠餓了的時(shí)候，它們選擇離開(kāi)其他老鼠的同伴去找食物。
