an animal species needs to have enough resources, like food and water, to survive in any given environment. however, because resources are limited, only a certain number of animals of a particular species are able to survive in a given habitat. the greatest number a habitat can support is known as the carrying capacity. if nothing happens to disrupt or unbalance the relationship between the animal and its habitat, the carrying capacity will remain stable. however, a carrying capacity is not fixed. if there is a significant disruption, such as an environmental event that alters the amount of available resources in the habitat, the carrying capacity will change.

now listen to part of a lecture in a biology class.

(male professor) ok, so lets talk about what happened to a certain type of insect, a moth, a red-and-black moth that lives in europe. these moths eat a plant called ragwort and they live in fields where the ragwort plants grow. now, there was a group of moth that lives in one of these fields and, for many years, there was a lot of ragwort growing there. so the moth had plenty to eat and the total number of moth in the field stayed pretty much the same.

but then one year it rained a lot less than usual and the ragwort didnt grow as well. the result was that the moth didnt get enough to eat and many didnt survive but even the ones that did survive didnt lay as many eggs as before. so that year the moth population in the field was quite a bit smaller. the next year, though, the amount of rainfall returned to normal and again many more ragwort plants grew and, once again, there was a lot available for the moth to eat. so that year the moth population increased and the female moth laid many more eggs than the year before. and now, after all that rainfall and plant growth, there were just as many moth in the ragwort field as there were before.

托福tpo33口语task4题目范文:

carrying capacity is the greatest number of animals a habitat can support. this number usually remains stable, but it might change when there’ s significant disruption.

just like the example of moths. moths eat a kind of plant called ragwort. the moths live in a place where there is a lot of ragwort, and the total number of moths that live there generally stays the same over the years. however, one year, it rained less, and ragwort didn’ t grow well. so many moths didn’ t survive because there wasn’ t enough to eat. also, female moths didn’ t lay as many eggs. therefore, the population of moths decreased. the situation returned the next year, and ragwort grew a lot better. as a result, the number of moths increased, and female moths laid more eggs.

now there are as many moths as there was before.

now listen to part of a lecture on this topic in a business management class.

(male professor)

so, let me tell you about my own experiences when i was working for a computer company a couple of years ago.

so, one day a co-worker and i suggested we should give our computers a design make-over: make them look more up-to-date. market research was showing that new customers said they would be more interested in buying our computers if they looked cooler. our technology was advanced but the outside design looked really old-fashioned.

at first, more than half the group supported us. there were a few senior managers here who didn’t support the design change. one o f the senior manager said, “our focus has always been on technology, changing the look is an unnecessary cost.”

almost immediately, some of our supporters changed their minds! even my co-worker changed his mind! when i asked him why after the meeting, he told me he didn’t want to make a bad impression on the senior managers. he thought that disagreeing with them might jeopardize his chances of getting a promotion by not looking like a team-player.

what about me? i hate to admit it, but, after a few hours of discussion, i started wondering if it was worth everyone’s time to argue about this? as more people sided with the senior management, i started to feel that i was the only one holding up the vote. everyone else seemed to think change wasn’t necessary. i voted against my own idea in the end.

so we unanimously decided to stay with the current old-looking design. but this decision ended up costing us a lot of money. that same year, our competitor came out with a new design that attracted some of our customers and prevented us from profiting from new customers.

the professor talks about groupthink which means sometimes people would make a bad decision as a group. in the example, the professor and his co-worker thought they need to change the look of their computers, but managers disagreed. so his co-worker changed his mind because he didnt want to leave a bad impression on the managers by not looking like a team player. in the end, the professor changed his mind too, because he didnt want to be the only person that’s holding up the vote. but they were all wrong, the same year, a competitor came out with a new design that attracted many of their customers.

man: hey, did you read about this plan?

man: why’s that?

woman: well, a lot of new students really need his, i mean, it, s not just about getting extra help with the course material, the/ ii probably also get information about things like taking notes or the best way to study for exams.

man: yeah, i barely even knew how to do those things when i first came here.

woman: neither did i. so these are things most students wind up having to learn on their own at first. that’s why so many of them have a hard time.

man: and if s probably good that they can work with somebody who has the same interests.

woman: right. that will be a real advantage: to get information about the classes you’re gonna need to take from somebody who’s already taken those classes. and they could recommend professors and tell you who the best advisers in the department are, things like that.

man: i see what you mean, so new students could get access to information about the program from another student, s point of view.

woman: exactly!

the familiarity principle

people tend to develop a preference for this theyhave previously encountered, things they arefamiliar with. social psychologists refer to thistendency as the familiarity principle. given achoice between two similar items, one they haveexperienced before and another that is new, most people will choose the familiar item. thisprinciple operates even when people are not conscious of their previous experience with anitem. once people have been exposed to an item - even if they do not recall having beenexposed to it - they will tend to prefer that item over other items to which they have not beenpreviously exposed.
