解析托福聽力中的定位
剛剛在前面我提過，托福主要是情商的考察，那么就是要求我們在最短的時間作出最正確的判斷。由于托福聽力最大的難點在于我們事先是看不到題的，所以整個托福聽力對于我們來說就是一個定位的過程。
解釋一下什么是定位，定位就是定位題點，判斷這里會出題，我一直相信，定準百分之一百的位，至少可以做對百分之90的題。
那么童鞋們，你們相信可以通過你們的筆記定準題點么?答案是definitely!剛剛在上面說了，托?？疾斓亩际翘厥恻c而不是一般點，并且不論是什么場景，他的題點位置都非常固定，主旨(包括開頭和結尾)，分論點和分論點的舉例及supporting details,然后就是語義理解處。而這些都是我們可以判斷出來的。
關于主旨，首先位置很固定，就是開頭處和結尾處，而且有明顯的主旨句型(開頭處)因此，開頭處跟在today后面，并且反復重復的詞一定是主題詞，還是以 chaffinch舉例。注意下面的這段原文
So today we’re gonna talk about song development in birds and how—you may be surprised to know—the songs of most songbird species are learned—not completely instinctual—which is what we used to think…so I’d like to start things off today by, um, centering our discussion on the chaffinch.
The chaffinch is a type of European songbird, and we’re gonna use the chaffinch’s song development as illustrative of songbirds’ song development in general, because many other songbirds follow this same pattern, this pattern of learning songs.
看我標注紅色的地方，這里是關鍵詞，反復重復的都是song, development所以這就是本文要說的主旨。
而我剛講的定位找AA，答案找AB就是這樣一個理論
托福做題的過程，就是一個同義詞改寫的過程
還記得OG里面的第一個conversation么?里面的學生說
I have some quick questions about how to write up the research project I did this semester, about...climate varation.
原文中的定位詞相當于是write the project
再看正確答案中的write the report
write就是我講的AA，而project就是我說的AB，同義詞替換
那么我們回頭再看一下關于song development的lecture song development就是AA
而答案中的How it develops from an early age就是AB，嘿嘿，明白了吧
這是我關于這篇文章的筆記，我會按照筆記說定位方法
OK，因為我們說過了，文章開頭是一定會出題的，而且song dvlp反復重復，所以第一個題點我就定在了，看到劃得位置了么
第二個位置，定在了關于subsong的舉例的位置，因為舉例屬于supporting detail看到了么baby反復重復，所以選B
23. How does the professor introduce her description of the sounds a chaffinch makes during subsong?
She contrasts the subsong of a chaffinch with the subsongs of other songbird species.
She compares the sounds a chaffinch makes to those a human baby makes.
She describes the sound of an adult chaffinch’s full song.
She reminds the class how scientists define begging ca lls.
結尾處，相當于主旨，而且重復，出題，看到我劃得exposure，所以最后一題選C
20. What is the evidence for chaffinches’ having a sensitive period for song learning?
They begin to practice their song in the spring.
They do not develop full song until their second year.
They need little exposure to adult song in order to learn it.
They do not make many sounds for the first five weeks of their lives.
總之，一定要用筆記整理出聽力的結構，定準結構點，做題才會準確，有效~
