And then, with that knowledge, you’ll make a second observation of the same child to see if the expected developmental behaviors are exhibited.StudentCan you give me an example?ProfessorWell, um, if you observed a 4yearold child, for example, my daughter is 4 years old, you might read up on Piaget39。ll need to do some research, too. Then you39。TPO13 ListeningSection 1 Conversation 1 已整理NarratorListen to a conversation between a student and his psychology professor. ProfessorGood afternoon, Alex! Can I help you with something? StudentWell, I wanted to talk with you about the research project you assigned today. I um... hope you could clarify a few things for me.ProfessorI39。ll write a paper that39。s Stages of Cognitive Development we covered those in class.StudentAha...ProfessorAnd most likely, what stage would a child of that age be in?StudentUm... the preoperational stage?ProfessorExactly. If that39。s perspective.ProfessorUm…Hmm...StudentBut what if she doesn’t? I mean, what if she doesn39。ll stop by the education department office this afternoon.ProfessorAnd if you have any trouble or any more questions, feel free to e by during my office hours.Lecture 1 已整理NarratorListen to part of a lecture in a city planning class. ProfessorIn the last 50 years or so, many American cities have had difficulty in maintaining a successful retail environment. Business owners in the city centers or the downtown areas have experienced some financial losses, because of a city movement of people out of the cities and into the suburbs. In general, downtown areas just don39。s a pretty simple concept really. It39。s start with the location. In choosing a specific location for a pedestrian mall, there are in fact two considerations: proximity to potential customers, um...that39。s location, but what about design? Well, design doesn39。t until a convention center and a parking garage were built about a decade later that the mall started to be successful.Lecture 2 已整理NarratorListen to part of a lecture in an ecology class. ProfessorSo, um, continuing our discussion of ecological systems, whole systems, the main thing to keep in mind here is the interrelationships. The species in a system and even the landscape itself, they are interdependent. Let39。s like there39。s something about wetlands and ground water too.ProfessorOK, good! Wetlands have a big effect on groundwater, the amount of water below the surface of the land. Think of wetlands as, um, like a giant sponge. The earth soaks up a lot of this water that39。s go back to where you were headed before, Mike, you mentioned a change that occurred after Europeans came to North America. MikeYeah, 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。s the crucial species that keeps the system going. Now beaver populations are on the rise again, but there39。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 half an hour long.StudentSo, it’s a video library, basically?ManagerYes, but unlike the library, you can39。s probably already started watching it...ManagerNo problem. We39。s written to evoke, to make you, the audience, have some kind of emotional experience through the use of imagery, um, some kind of predictable rhythm. And usually, but not always, there39。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 studentWell, there39。s a...he39。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 very conscious of the particular rules of social behavior he has to live up to somehow. And all of his actions are for the purpose of proving that he is an upright, moral, wellmannered, wellbehaved individual. You may have noticed that in Chanson poetry there isn39。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。m going a bit out of order here. Um… I39。ve got the asteroid belt, which contains about 90% of all asteroids orbiting the Sun. These asteroids are...like the terrestrial planets in that they are posed mostly of rocky material and metals.Far from the sun, in the outer solar system beyond Jupiter39。s atmosphere. The larger ones that make it through the atmosphere and hit the ground are called meteorites. So meteorites are the ones that actually make it through.Now, we39。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?StudentMostly iron?ProfessorYeah, iron and some nickel, both of which are metals. And if you are trying to find metal... StudentOh! Metal detectors.ProfessorRight. Thank you. At least that39。m looking for this book The American Judicial System, and l can’t seem to find it anywhere. I need to read a chapter for my political science class.EmployeeLet me check in the puter. Um...doesn’t seem to be checked out, an
