Have you ever felt like you would do just about anything to satisfy your hunger? (16) 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. (17) 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. (18) 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 series of experiments with mice?
17. In what circumstances do mice venture into unsafe areas?
18. What is said about mice at the end of the passage?
选项
A、They search for food in groups.
B、They are overweight when food is plenty.
C、They prefer to be with other mice.
D、They enjoy the company of other animals.
答案
C
解析
浏览四个选项,从选项中的in group,overweight,prefer,with other mice,enjoy the company等词可推测,此题与老鼠的生活习性有关。题干问的是关于老鼠,短文最后说了什么。短文最后部分提到,研究表明,老鼠是群居动物,喜欢和其他的老鼠待在一起,故答案为C。A项(它们成群结队地寻找食物)与短文内容不符,因为短文最后提到当老鼠饿的时候,它们会选择离开同伴去觅食,故排除。B项(当食物充足的时候,它们会很胖)短文未提及,故排除。D项(它们喜欢其他动物的陪伴)属于偷换概念,短文说的是它们喜欢其他老鼠的陪伴,故排除。
