【正文】 ve heard of studies in which people hear a list of related words. Um…let39。t think they39。s still here in the library, so people must be using it. You know this seems to be a very popular book tonight. We show six copies。s rare to ever find one. I mean it39。ll just cover some basic info about them. OK, ets and asteroids. It might help if you think of…r emember we talked about the two classes of plas in our solar system, and how they differ in position, the terrestrial plas like Mars and Earth, posed largely of rocks and metals, and the large gas giants like Jupiter? Well, the solar system also has two analogous classes of objects smaller than plas, namely asteroids and ets. Relatively near the sun, in the inner solar system, between Jupiter and Mars, to be precise, we39。t central to people’s lives. More peaceful times meant there was more time for education, travel, more time for reflection. Another name for Romance poetry that39。s pare that to the hero in the other poem. The other poem is an example of what39。t know a lot about the authors. It39。t want to miss anything, you know, and he39。m not sure, but urn... is this the Carter language lab? Manager Yes, it is. How can I help you? Student I39。cuz there is no dam, so the ecosystem would be pletely different. There would be fewer wetlands. Professor Exactly. So now let39。cuz if you go back before Europeans settled in North America, like before the 1600s, back when native Americans were the only people living here, well, back then there were a lot of beavers. But later on, after Europeans... Professor Oh, OK, wait. I see where you are heading with this. But before we go into how European settlement affected the ecosystem, tell me this: what kind of environment do beavers live in? Think about what it was like before the European settlers came. We’ll e back to where you were headed. Kate OK, well beavers live near streams and rivers, and they block up the streams and rivers with like logs and sticks and mud. You know, they build dams that really slow down the flow of the stream, so then the water backs up and creates like a pond that floods the nearby land. Professor And that creates wetlands. OK, tell me more. Kate Well with wetlands, it39。t drive into the mall area, well then they need to have easy access to it. OK, so that39。ve e up with some ways to attract more people to shop downtown was by creating pedestrian malls. Now, what is a pedestrian mall? It39。d be thinking mostly about herself and her own needs, and might not be able to see things from anyone else39。ll need to do some research, too. Then you39。ll write a paper that39。s perspective. Professor Um…Hmm... Student But what if she doesn’t? I mean, what if she doesn39。s a pretty simple concept really. It39。s location, but what about design? Well, design doesn39。s like there39。s go back to where you were headed before, Mike, you mentioned a change that occurred after Europeans came to North America. Mike Yeah, well, there used to be beavers all over the place, um, something like 200 million beavers, just in the continental United States. But when Europeans came, they started hunting the beavers for their fur 39。m taking first year Spanish this semester. Our professor says we need to e here to view a series of videos. I think it39。s probably already started watching it... Manager No problem. We39。s still contested somewhat, but we are pretty sure about who the Chanson poems were written for. That is, they were written for knights and the lords, the nobility that they served. The poems were sung, performed by a minstrel, a singer who travelled from castle to castle, singing to the local lord and his knights. Ah... well...um... would someone summarize the main features of the Chanson poem you read? Male student Well, there39。s called Romance poetry. And the hero in the romance poem was also a knight. But what made the knight in Romance poetry different from the knight in Chanson poetry? Well, first the purpose of the hero39。s often synonymous with it is troubadour poetry. Troubadour were the authors of these new romance poems. And we know a lot more about the troubadours than we do about the Chanson authors, because they often had small biographical sketches added to their poems that gave pretty specific information about their social status, geographical location and a small outline of their career. This information wasn39。ve got the asteroid belt, which contains about 90% of all asteroids orbiting the Sun. These asteroids are...like the terrestrial plas in that they are posed mostly of rocky material and metals. Far from the sun, in the outer solar system beyond Jupiter39。s easier to find an iron meteorite or a stony iron. Anyone guess why? Look at their names. What do you think iron meteorites consist of? Student Mostly iron? Professor Yeah, iron and some nickel, both of which are metals. And if you are trying to find metal... Student Oh! Metal detectors. Professor Right. Thank you. At least that39。 none are checked out, and yet you didn39。ve hired a replacement yet, so yeah, the unshelved books can get a bit out of hand. Student This may sound a bit weird, but I39。s say a list of different kinds of fruit. After hearing this list, they are presented with several additional words. In this case we39。m not sure how that would work for you. And...oh we get paid the normal university rates for student employees. Student So who do I talk to? Employee I guess you’d talk to Dr. Jenkins, the head librarian. She does the hiring. Lecture 1 已整理 Narrator Listen to part of a lecture in a psychology class. Professor We’ve said that the term cognition refers to mental states like knowing and believing, and to mental processes that we use to arrive at
