托福听力该如何记笔记呢 托福阅读

　　托福听力如何记笔记？一般来讲，教授专家们会在开篇直接说出他们接下来要讨论的主题，然后给它一个定义，接下来前有古人，后有来者，经过一番挣扎之后，他们终于明白这是个什么原理了。有时候还要展望一下未来，当然未来都是不确定的喽。
　　我们来看一下笔记：
　　讲座主题: sunspots
　　一般定义: spots on sun's surface
　　渊源: Ancient Chinese 165; European didn't believe because they think the sun is perfect；something else；shadows of planets
　　推翻: 伽利略，望远镜 shape wasn't circular and it changed a lot；might be clouds in atmosphere
　　各种假说:
　　Schwabe 17 years, 10 year-cycle
　　Wolf 40 years, 11 year-cycle = magnetic field cycle
　　展开研究: Everyone started study Earth and Sun 关系
　　结论: sunspots are magnetic fields
　　再来看一下题目：
　　1. What is the lecture mainly about?
　　A. The importance of record keeping in the development of hypothesis
　　B. The relationship between sunspots and Earth’s geomagnetic cycle
　　C. The progression of scientific knowledge about sunspots
　　D. The effectof sunspots on Earth’s climate
　　2. Why did European astronomers before the time of Galileo not believe sunspots were on the Sun's surface?
　　A. They based their beliefs on earlier observations by Chinese astronomers
　　B. The idea was contrary to their beliefs about objects in space

　　D. The sunspots were not always visible
　　3. Which hypothesis regarding sunspots did Galileo challenge?
　　A. sunspots are shadows of planets crossing the sun
　　B. Sunspots are clouds in the solar atmosphere
　　C. Sunspots are evidence of the sun’s rotation
　　D. Sunspots are evidence of magnetic fields
　　4. What was the importance of Schwabes's observations?
　　A. They determinedthe age of sunspots
　　B. They established that sunspots appear in cycles.
　　C. They proved that sunspots were actually on the sun
　　D. They showed the reason that sunspots change their shape
　　5. What is the professor's attitude toward Schwabe's and Wolf's research?
　　A. He is surprised that the research is contradictory
　　B. He is impressed by how many years were spent on the research
　　C. He had difficulty believing that research should take so long
　　D. He doubts that the research is given enough credit by modern astronomers
　　6. Why does the professor imply about the discovery of a relationship between the sunspot cycle and Earth's geomagnetic cycle?
　　A. It proved that Galileo's cloud hypothesis was correct
　　B. It showed how conditions on Earth can affect the sun
　　C. It was the start of modern astronomy
　　D. It led to a period of intense scientific research
　　加上单词理解和同义替换，答案是不是就明了了
