例（TPO10 LECTURE2）The Nightshade family is a category of plants which also includes many that you wouldn’t want to eat.与主题不相关的地方
多出现有学生插话，比如，I’m sorry, professor, did you just say ……，或老师插话，比如oops, let me back up a bit, before I go on ……例（TPO10 LECTURE2）
Student: I’m sorry Professor Jones. But I mean yeah ok. American crops have probably contributed a lot to European cooking over the years. But…Professor: But have they really played any kind of important role in European history?
我们先看个例子TPO10 LECTURE2：13 What does the professor imply about certain plants in the nightshade family?
AThey grow best in Mediterranean climates.BTheir leaves are high in nutritional value.
CThey were mistakenly believed to be related to potatoes.DThey are dangerous when eaten by human beings.
（Bingo！主要考察细节中的explanation的专有名词）14 What does the professor imply about Thomas Jefferson's attitude toward tomatoes?
AIt was typical of his unconventional way of thinking.BIt helped to advance his political career.
CIt changed the eating habits of North Americans.DIt helped to make tomatoes popular in Europe.
（学生提问的地方，答案是老师的回答）15 According to the professor, what was the long effect of the introduction of American corn and potatoes to Europe?
AIt had a negative effect on the nutritional intake of people living near the Mediterranean Sea.BIt contributed to a shift in the balance of power from southern Europe to northern Europe.
CIt encouraged the development of new types of cuisine in southern Europe.DIt led to the failure of many native European grain crops.
（不是facts，不是examples，不是irrelevant contents，更不属于解释，那么它应该属于支持内容与文章主旨联系。答案在lecture的最后教授所提到的Potatoes soon spread to France and other Northern European countries. And as a result, the nutrition of the general population improved tremendously and population soared in the early 1800 and so the shift of power from southern to northern Europe continued.）16 According to the professor, what is one of the reasons why potatoes became popular in Ireland?
APotatoes were more nourishing than native Irish food crops.BPotatoes grew better at higher altitudes than native Irish crops.
CPolitical leaders in Ireland encouraged the cultivation of potatoes.DPeople in Ireland were not aware that potatoes are members of the nightshade family.
（又是一个例外，应该属于支持内容与文章主旨联系。而且这里完全可以出成双选题Well, why do you suppose it happen? Because 1 potatoes have the ability to provide abundant and extremely nutritious food crop, no other crop grew in North Europe at the time had anything like the number of vitamins contained in potatoes. 2 Plus, potatoes grow on the single acre of land could feed many more people than say, wheat grow on the same land. 一个问题两个原因，构成并列关系即构成双选题。）17. Listen again to part of the lecture. Then answer the question.
What can be inferred about the professor when she says this:AShe expects the student to provide an answer to her question.
BShe is surprised by the student's question.CShe thinks that she knows what the student was going to ask.
DShe expects other students in the class to express their opinions.（学生有疑惑，语气不一样的地方，此题不意外，而且完全能猜到题）
例16，一问一答，有提问有回答的地方。问题一定要听清楚，问题通常是下面那段话的Topic Sentence，同时需要注意的是回答的内容很容易出成一道题，若回答中存在并列关系可能会有多选题。我们做一个简单的小结，以前听的时候我们过分关注了有解释有例子的地方，其实听力中的细节点应该包括以下几点：topic sentence + explanation（专有名词） + examples + student/professor question + the answers + conclusions以及insertion（语气不一样的地方）。
