一、难词注解
Wetlands 湿地;沼泽地
swampy land 湿地

estimate vi. 估计，估价n. 估计，估价;判断，看法vt. 估计，估量;判断，评价

二、长难句分析
Then we enter those data, information about what the landscape look like before and after the wetlands were drained.
难句类型：
时间状语从句，before and after +从句
三、考题对应考点
6. Professor: Uh…but these are the obvious changes, but there are also less obvious changes like the climate. One interesting case of this..uh…of changes in the local land use causing changes in climate, specifically the temperature, is in Florida.转折原则，but后面的【local land use causing changes in climate, specifically the temperature, is in Florida】就是教授要表达的主旨，即为答案 B.
7. Professor: Oh yes, farmers moved south, but the land was not suitable for farming. You can’t grow oranges in wetlands. So farmers had to transform the wetlands into land suitable for farming. To do that you have to drain the water from the land, move the water elsewhere, and divert the water sources such as rivers. Hundreds of miles of drainage canals were built in the wetlands.听力的因果原则，so后面的内容是重点，在最后听到了需要的关键词【canals】再回忆之前听到的内容，从【So】这个标志词开始的就是答案。即为 C .
8. Student B: Is it some global temperature change, or weather pattern, like El Nino or something?
Professor: Well, there are two theories: one idea is as you suggest that major weather patterns, something like El Niño, are responsible. But the other idea, and this is the one that I personally subscribe to, is that the changes in the temperature pattern have been brought about by the loss of the wetlands.问答原则，听到学生提问开始，教授又以【Well】开头，便可知道教授接下去说的话是对于学生提问的解答。而教授说【there are two theories】，提示我们要听清楚教授赞成的是哪一种理论，再之后【this is the one that I personally subscribe】意味着后面就是答案。 教授的意见是【the loss of the wetlands】是 Florida 气候的主要成因而不是 El Niño。也就是A选项。
9. Professor: Well, think about what we’ve been studying so far. We’ve discussed the impact of landscapes on temperature, right? What effects does a body of water have on an area?
Student A: Oh yeah, uh… bodies of water tend to absorb the heat during the day, and then they release the heat at night.
Professor: Yes, exactly! What you just said is what I want you all to understand. Bodies of water release heat and moisture back into the environment.强调原则和问答原则。【Yes, exactly!】表示教授对于学生完完全全的肯定，非常清晰地显示出学生所说的就是答案：C.
10. Student B: Hmm…Do we know what the temperature was like back then?
Professor: Well, we were able to estimate this. We have data about south Florida’s current landscape, uh the plant cover and we were able to reconstruct data about its landscape prior to 1900. Then we enter those data, information about what the landscape looked like before and after the wetlands were drained. We entered the data into a computer weather model. This model can predict temperatures and when all the data were entered, an overall cooling trend was predicted by the model.听力的强调原则和特殊年份和地名原则。从听到【data】这个词再到【1900】，就 可以知道这个问题所需要的解答出于这一段话。【landscape】的反复出现，也提示我们这是一个关键词。 再从整段的意思来看，教授讨论的是【The landscape characteristics of south Florida】,所以答案是 D.
11. 重听部分: Farmers moved south.
Professor: Wetlands have their own unique ecosystems, with plants and animals with special and interesting adaptations. Very exciting but it’s not what we are talking about today. Um…where was I?
Student A: Farmers moved south. 听力转折原则和问答原则。听完这段可以很清楚地发现学生 这句话是回答教授的问题的，而教授的问题就是【Um...where was I?】我刚刚说到哪里。所以答案是 A，提醒教授她之前说的点。
听力文本结构框架：
本讲座主要讲的是以弗罗里达为例，解释土地的变化会影响气候，特别是温度的变化。解释了湿地减少影响气温的原因。
