　　阅读材料Listening Script

　　The following is the script of the lecture that you heard and were asked to summarize.

　　You know, often in science, new findings force us to re-examine earlier beliefs and assumptions. And a recent study of meerkats is having exactly this effect. The study examined the meerkat‘s behavior quite closely, much more closely than had ever been done before. And some interesting things were found.., like about eating habits.., it showed that typically meerkats eat before they stand guardso the ones standing guard had a full stomach! And the study also found that since the sentinel is the first to see a predator coming, it‘s the most likely to escape... because it often stands guard near a burrow, so it can run immediately into the burrow after giving the alarm. The other meerkats, the ones scattered about looking for food, are actually in greater danger.

　　And in fact, other studies have suggested that when an animal creates an alarm, the alarm call might cause the other group members either to gather together or else to move about very quickly, behaviors that might actually draw the predator‘s attention away from the caller, increasing that animal’s own chances of survival.

　　And what about people？ what about some human acts that might be considered altruistic? Let‘s take an extreme case, uh, suppose a person donates a kidney to a relative, or even to a complete stranger. A selfless act, right? But... doesn‘t the donor receive appreciation and approval from the stranger and from society? Doesn‘t the donor gain an increased sense of self-worth? Couldn‘t such non-material rewards be considered very valuable to some people?
