托福听力30天备考计划第十二天：TPO13 L+C

　　今天我们来讲解TPO13的一道题目的解题思路。【TPO13听力文本(Conversation+Lecture)】

　　我们在听文章的时候，通过一些关键词可以预测出一些知识点被出考题的几率很高，比如在第三篇lecture(环境科学)中，当我们听到一些一段话时，就应该提高紧惕。例如一下语段：

　　Well, there are two theories. One idea isas 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 had been brought about by the loss of the wetlands.

　　首先，听到there are two theories这里的时候，就应该预测到，接下来会从两个方面讲关于气候变化的理论。One…the other…就是在列举，也是考察重点之一。Like 引导了El Niño的一个例子。例子是绝对的重点而当我们听到but的适合也要绝对的注意，这里是高危地带。this is the one that I personally subscribe to, is that…这是一个强调句型,表示之后的理论正是教授赞成的理论。以上提到的各个点都是常出考题的关键信号，当这些信号以如此高密度的频率出现的时候，这个地方几乎在被听到的时候就能被确定预测到会出考题了。

　　事实上，这里出的考题是：

　　What does the professor imply about major weather patterns such as EL NIÑO?

　　A. She does not believe they are the main cause of the changes in Florida’s climate

　　B. Sheis certain that they have caused a worldwide decrease in the number of frosts

　　C. She believes they contributed to the increase of citrus production in Florida

　　D. She does not fully understand what causes them

　　因此the loss of the wet lands才是气候变化的主要原因，而不是but之前提到的El Niño。
