In the reading material, the author cast doubts that Marco Polo never travelled to China in the 13th century. However, in the lecture, the professor holds the opposite opinion in (to) the listening material as (for) following reasons.

To begin with, in the reading material, the author claimed (可以简化为 the reading material maintians)that Marco Polo never used any Chinese or Mongolian place-names. （应该写一句marco的是persian语的地名）Nevertheless in the 13th or (to) 14th century of Europe, as professor stated that,(这个也可以不要) Persian was the major language (in trade). As a result, it is acceptable that Macro Polo just borrowed the names of Chinese locations in Persian language to describe places of China.

Furthermore, the author of this article provided the evidence that Macro Polo never mentioned the cultural practices of Chinese, such as the Chinese loving tea(改成 "tea drinking populartiy in China, OR Chinese's love for drinking tea" is better). While the professor argued that though there is omission of reference to the popular pastimes and cultural practices,(最好具体说是tea drinking practice) yet it is possible that only southern people in China would like （不是愿意，是只有南方形成了，北方还没形成） to drink tea in that period. (while、though、yet三个词选一个就够了，都是表转折的)So Macro Polo failed to the south of China and only had been to the9 mNorth of China, （lecture中好像是说marco绝大部分时间都呆在北方，不是说marco没去过南方）in which （where） it was not popular to drink tea. 最后一句意思不是很通畅。
0 ^, J3 ]/ Z5 l1 e" @7 u8 F

Finally, the author was not supportive of the idea that Macro Polo had been to China because there is no evidence that Marco Polo served at the court of Mongol ruler. However, the professor analyzed that it is possible that people were usually referred by different names in the stage of China （这么说有点wierd，直接用at that time 就好）. So the name of Macro Polo was probably replaced with （by） another name or maybe in the official documents his name was simply lost, (好像不是说他的name lost 了， 是记录他活动的材料simply lost了)when Macro Polo was appointed to the post of governor of Yang Zhou. （在朝廷服务和当扬州知县是在一起说的，最好不要拆开一个放开头一放结尾）

1.没有小结段？可能是个人风格吧，我觉得时间够还是写一个，一两句就好。
2.时态问题，OG上的范围在转述reading和lecture的意见时，都用的一般现在时，如 the professor thinks... 所以我觉得不管用现在还是过去，统一的好。
3.基本要点都听到写出来了，一些细节和句子连贯建议加强。

欢迎探讨^_^

The importance of a teacher on education is manifest. Some excellent teachers are famous for their methods to impart knowledge; others gain fames by giving confidence to students. Then here comes to the question what quality is more important. In my perspective, teachers should spend more time helping students establish confidence than imparting knowledge and my reasons are as follows.

To begin with, to help students to be confident is more important than to impart them knowledge. Although it is a teacher's obligation to teach knowledge and skills to their students, yet there are other factors playing important roles to improve students' study, such as study methods and confidence. Actually the importance of confidence is more manifest than other factors. If a student is frustrated and afraid of studying, never could he avoid failing in his future study no matter how learned teachers are or how smart the study method is. What is more, at the stage of university education, it is not the teacher but the students themselves who play the dominant role on study. I will take my university for example. A student can choose an instructor from several professors when selecting a class; however there is no manifest differences among instructors' ability to teach. Eventually those who are confident in study perform excellent in the final examination. In this manner, I am supportive of the point that teachers should spend more time helping students have confidence.

The second reason is because confidence is not only important to a student's study but also helpful to his/her life. Excellent teachers are not those who only impart knowledge or teach skills to students, but those who enlighten others. Without confidence in study, a student probably fails to gain credits. Still losing confidence in life, people possibly suffer from the intention of suicide, never to say to be successful on the academic field. Nevertheless, conversely if a student is fortunately encouraged by instructors when frustrated in life, such tragedy would not happen. This reminds me of the story of Winston Churchill. When Churchill was young, he failed to excel in his study. At first, the teacher of his secondary school asserted that rarely would Churchill gain any success. Ironically, encouraged by the instructor of his high school, Churchill was admitted to university through his endeavor and finally became an outstanding politician in Britain. Thanks to his instructor of high school, otherwise we would lose a great fighter in the Second World War. Based on the analysis, a teacher’s kindness of encouraging students has a significant influence on a person’s life.

In sum, though imparting knowledge is one of important responsibilities to teachers, yet the importance of helping students establish confidence are more manifest. For one thing, it helps students to improve study; for the other thing, people can regain the confidence to life.

In the reading material, the author question the gaint-impact theory that the Moon came from material of earth and was formed by gaint collision. However, in the lecture, the professor disagree with this contention based on the following analysis.

Firstly, the author of this article argue that because no evidence of huge mark on the surface of Earth has been found, the validity of the giant-impact theory is doubt. Nevertheless,  the professor stated that since the collision happened 4 billion years ago, it is quite possible that the mark of this gaint collision has disappeared.

Secondly, the author of this paper cast doubt on the gaint-impact theory based on the contention that if the Moon is part of the Earth, they should have the same composition, yet the evidence shows that rocks on the Moon contain few volatile substances such as water. The professor, however, proposes that because of the high temperature on the Moon volatile substances as water has vapourated into space and that is why no such materials as water could be found on the Moon.

Finally, the professor explain the fact why the Moon has a density compared to the terrestrial planets. Though recent findings reveals that the moon's core constitutes only 2-4 percent of its total mass, compared to a terrestrial core with about 30 percent of the Earth's mass, yet it is because the Moon's substances is just part of the Earth's surface, which has a relatively lower density. And that is completely what the professor found about the Moon.

In conclusion, because of the reasons above, the professor could not agree with the point of the reading material.

"All splendor in the world is not worth a good friend". The voice of Voltaire can best describe the importance of the friends. However, there is not always peace and harmony between friends and conflicts cannot be avoided. Thus here comes to the question whether letting a friend make a mistake is better than saying or doing something that may destroy the friendship. In my perspective, Allowing a friend to make mistake to maintain the friendship is more important and my reasons are as follows.

To begin with, friendship is an valuable treasure to people and should not be destroyed by trivial conflicts. True friends are those who care us and offer help to us when we trap in trouble; trusty friends are those whom we can confide our secrets to without worrying about they betraying us if we are not happy; long-lasting friend are those whom we never worry to lose even without contact for a long time, nevertheless when communicating with them after half a month we will find a warmness runs into our heart. How can we abandon the great friendship just because of our friends making a mistake, even in some cases it is not easy to judge whether they are wrong or not. Still even the Bible teaches us to forgive other people, how could not we give an opportunity for our friends to correct them? This reminds me of a lesson from my schoolmates. Once, two of my schoolmates had been good friends for several. However, their friendship was broken just because one of them made a joke on the other. Neither of them would like to forgive each other. The lesson of my schoolmates gives us a lesson. Therefore, never letting a friend make a mistake makes no sense to maintain the friendship.

Furthermore, letting a friend make a mistake does not mean letting friends always do wrong things. Actually we should let our friends make a mistake, and when we can control our temper, we should have a sincere talk to our friends to point out their mistake. On one hand, we preserve the friendship; on the other hand, we help our friends to correct problems. Since no one can avoid making mistake, if the mistake is not severe illicit we can let our friends make a mistake at first. Because when people are rage, hardly could any word have an effect on them. As a result, it is more advisable to let friends find their problems later, when they are peace. In this manner, it is more possible for friends to accept suggestions. Based on the analysis, I would support the view that letting a friend make a mistake is better.

In sum, since the problems are not severe and the friendship is the most cherish treasure in the world, I totally agree with the idea that letting a friend make a mistake is better than ruining the friendship.

mistakes的理解比较窄，局限于朋友之间的冒犯之类的错误。
正面观点貌似不太好写，你的两点理由整理下应该是这样的吧：
1. It is not easy to persuade some people that what they are going to do is wrong, so we can risk the danger of harming our friends' feeling.
2. Letting  a friend make some mistakes will give them more impressive experience and help them avoid making the same mistakes in the future.

In the lecture, the professor questions the contention of the author that Tunguska is caused by swamp gas explosion rather than an asteroid based on the following analysis.

Firstly, although the author of the reading material provides the fact that there was no fragment or any impact craters left in Tunguska after repeated expeditions; yet the professor points out that it was 19 years later when scientists search the traces of asteroid explosion. Meanwhile, scientists came to find fragments in Canada when the explosion happened after two weeks. Therefore it is acceptable that no traces had been found in Tunguska.

Secondly, the author casts doubt on the evidence that there was no smoking gun in Tunguska. However, the professor explains that it is because explosion could not happen in that low atmosphere before it hit the Earth. Thus, there was no crater left.

Finally, the professor argues that if Tunguska explosion was caused by swamp gas, the huge fireball could not be concentrated on one spot. So it is impossible that the explosion should be ascribed to the swamp gas explosion.

In conclusion, because of the reasons and evidence from the professor in the lecture, the Tunguska explosion is caused by an asteroid not by swamp gas explosion.

In the reading material, the author casts doubt on the practice of prescribed burning. However, in the lecture, the professor acclaims that this point is not valid as following reasons.

First of all, although in the article the author warns that prescribed burning of prairie would cause environment problems such as air pollution and the global warming. Nevertheless, the professor points out that prescribed fire can change forests into ashes. Still it is a fern to forests because it can warm soil which is beneficial to seeds. In addition, a planned fire can stop a big wild fire. These advantages are not what the disking have.

Furthermore, in the reading material the author questions the safety of prescribed fire because it is unpredictable. Since there are too many what-ifs and unexpected dangers to justify prescribed fire, it is too dangerous to use prescribed fire. However, the professor argue that the prescribed fire is usually planned for a long time and people know where and when it is set, so there is nothing to be afraid of.
Finally, the author of the reading material worries about the high cost of prescribed fire. According to studies, the cost of prescribed fire ranges from 10 dollars to 1,000 dollars per hectare, which depends on the size and nature of the burn. Yet in the lecture, the professor contend that actually the expenditure of prescribed fire is quite low, compared with the cost of fight wild fire which is 10 times of the cost of prescribed fire, never mention to its damage to homes and families.

Based on the analysis, because of the benefits, safety and low cost, the professor cannot agree with the idea of the author.

Still it is a fern to forests （sunlight的点）because it can warm soil which is beneficial to seeds and roots. In addition, a planned fire can stop a big wild fire. These advantages are not what the disking can have.

Furthermore, in the reading material the author questions the safety of prescribed fire because it is unpredictable. Since there are too many what-ifs and unexpected dangers to justify （应该是负态度词，如question）prescribed fire, it is too dangerous to use prescribed fire(第一句和第二句都是因果句，意思重复). However, the professor argue that the prescribed fire is usually planned for a long time and people know where and when it is set, so there is nothing to be afraid of.加个小小的总结就更棒了

Finally, the author of the reading material worries about the high cost of prescribed fire. According to studies, the cost of prescribed fire ranges from 10 dollars to 1,000 dollars per hectare, which depends on the size and nature of the burn. Yet in the lecture, the professor contends that actually the expenditure of prescribed fire is quite low, compared with the cost of fight （fight做什么讲）wild fire which is 10 times of the cost of prescribed fire, never to mention to its damage to homes and families.!

Based on the analysis, because of the benefits, safety and low cost, the professor cannot agree with the idea of the author that this point is not valid as following reasons. （和开头一样的，as following，难道还有下文吗）
