Today, I had a great thing to do, and that was led-student discussion. In this discussion, David, Rand, Hua and me were the learders to organize the students who attended the discussion.
The topic of discussion is about the right of using guns. Nowadays, many counties allow people to use guns, while having a gun is illegal in the other countries. That is the reason why we create this discussion. According to the discussion, some students told us that in their countries, such as the Middle East countries. However, they still need to have tests to get licenses, and they can just use guns for hunting. Some other students said that they can not have the guns with themselves in their countries. Furthermore, the Middle Eastern people said that they think that gun can protect their safety. On other hand, others believed that guns are very dangerous.
Today, we had very interesting discussion. Many students were here, even though some of them are a little late. In fact, in my opinion, we had a great time.

After talked with someone, I suddenly wanted to learn something about space. As a result, I chose and attended a lecture which is life beyond the earth on one Monday. Maybe this course is not including into the sheet in YUELI, but I was not sure. I was attracted the title of the lecture, life beyond the earth. However, it was very difficult, because I had never learned anything about this topic.
The topic of this class was living in space. At first, it was about elements of the artificial environment. The teacher taught something about how to create an artificial enclosed environment when the life is beyond the earth. The people still need the food, water and oxygen for the normal life. Furthermore, the professor showed some information on the internet. Secondly, it was about the journey to the stars and the generational ship. The journey is a bridge of the interplanetary distance can easily be done in the average human life. At the end of the class, the teacher told something about hibernation. I learned something about living in the space from the class.
This was a difficult class. There were so academic word, and the professor spoke very quickly. As a result, I think I still have a lot of thing that should be improve.

This weekend, my friends made a trip that was very special for me. The trip was a ice skating trip.
This trip happened in a very cold day. All my friends met in house which is next to my room, and we drove to the skating place, the Natural Ice Rink. Then one of my friends helped me to borrow the ice skates, because I was a new one for skating. After that we put on these ice skates. When I stood up, I found that wearing ice skates was not very comfortable. This kind of shoes was very heavy and stiff. When we arrived at a skating rink, the skating rink was not big as I thought, but it was beautiful. Because it was my second time to skate, I felt very nervous. However, my friends were very nice and they helped me to enter the rink. One of my friends taught me, even though it just was her third time to skate. Maybe because I am not good at sport, I still did not know how to skate when we finished this trip. In contrast to me, many new learners could skate better than me. It was a very good experience. Even though I gain nothing about skating, I really had a great time.

Today, I was so happy, because I do not have homework to do. As a result, one of my friends asked me to attend a lecture, named the nature and growth of scientific thought. The class was a little bit difficult to understand.
Actually, this class was something about physics. The professor showed some pictures in his power point, and these pictures were about the change of voltage. The electron which has high energy moved quickly and can jump out, while the electron which has less energy moves slowly. The teacher gave a equation: E = hv. Secondly, the professor taught the visible spectrum of hydrogen. There were four lines in the visible point. Finally, an intensity of an object emit electron. Radiation can be used to detect the temperature. This lecture was very interesting and good.
This class was better than last lecture, and the professor gave some pictures. These pictures could help students easily understand. Some part of this class I could understand, and that make me so happy.

I had a very interesting day with friend. First, friends took us to a shop where people can paint the bisque. I chose a big plate. Before we paint these bisques, the staff taught us how to do that. We should paint the color three times, if we wanted to have dark color. I chose green and used this color for outside of the plate and yellow for inside. Because I wanted a light green, I just painted twice. To compare with bisque, it was much easier to paint the whole plate. The plate was very dry and paint was not wet enough. I did not want to make the color bit and bit, because I did not paint well last time. I must draw lessons from experience. After we finished painting the bisque, we are some KFC and diet Pepsi. Then we came back home. One of my friends said that he would bring bisques when the bisques would be dried. However, I think that it will be a long time for me to wait for the plate to become OK, because I want to get my plate as quickly as possible. It was a wonderful time to play with may friends in that shop.

Report:
Today was an interesting day because we had a chance to attend a lecture. There were three choices for us to choose because we had to attend lectures which started at 9:30. Finally, David, Tien Elyana and I found us in the some group, and our lecture was Introduction to Fitness and Health, which was in Curtis Lecture Hall L. Then, all the students went to find the lecture.
After all of the students had their choices, we went to the lectures. Because most of us did not know where these locations were, the teacher led us to find the places. On the way, four students left and went to another place, and rest of us with the teacher, continued to search for Curtis Lecture Hall. We spent some time finding Curtis Lecture Hall outside the building in the cold weather, and then we looked for Hall L around the whole building. Finally, we went upstairs and found it on the third floor, and we went in quickly.
When we entered Hall L, the lecture had already begun. Firstly, the professor reviewed some material which he had taught the previous week in a few minutes, and then he started something new. In the lecture, he taught the factors affecting health which include heredity, age, sex, body size and composition, training status and environmental condition. Secondly, in a section about how indirect tests predict VO, the professor explained that people can predict oxygen consumption from sub maximal heart rate repose. Then, the professor gave an equation: Blood Pressure=Cardiac Output ×Total Peripheral Resistance. Finally, the professor gave some charts and tables to show some data about blood pressure.
During the lecture, the professor was interesting. He did many actions to explain what he was talking about. He, for example, performed some sport exercises to explain blood pressure in the arms and legs. At the same time, most of the students listened very carefully. Some of them typed summaries on their laptops, and some of them just paid attention to the lecture, for example.
In the lecture, I did not feel very good. This may be because the lecture was so academic that I could not understand many words. It may be also because I did not have some background information about blood pressure. As a result, it was a little difficult to understand. However, I liked the lecture because the professor was interesting, and I did not find the class boring. Furthermore, I could understand one student’s question and the professor’s answer. To be honest, I liked this professor‘s class, but I was sorry that there were so many new words.
In conclusion, today’s lecture was a good way to show us real life in university. I will choose another lecture when I have free time so that I can improve my English.

Summary:
According to “Implications for Agriculture and Rural Development” in “Biofuels” by Antony Rowe (2007), nowadays, because of rising biofuels production, the need of agricultural feedstock makes crop prices higher and higher. The author noted that many different kinds of feedstock and technologies can be used to produce biofuels, and because of these farmers can produce “underutilized forms of biomass” (Rowe, 2007, pg.122) and make more land to produce agriculture. The writer stated that “biofuel programmes” (Rowe, 2007, pg.123) maybe an important reason of rising employment in rural areas nowadays and in future. The author mentioned that biofuels seem to be a “possible solution” (Rowe, 2007, pg.127) which can help agricultural surplus in some developing countries. Rowe explained that there are some benefits to “rural communities” (Rowe, 2007, pg.129). The author reported that even though there are many “small-scale biofuel production” (Rowe, 2007, pg.133) now, in future, “large-scale” biofuel production will become the main stream (Rowe, 2007, pg.133). The author described that producing biofuels can make rich farmers more wealthy, while it also can lead poor farmers into more poverty. Furthermore, the writer showed that because the requirement of biofuels has been increased, the certain food prices has became higher and higher, and these will lead to some social problems.

Summary:
According to “Energy Balances of Current and Future Biofuels” in “Biofuels” by Antony Rowe, people use two different methods, “energy balance” and “energy efficiency” (Rowe, 2007, pg.160), to evaluate the product of biofuels. The author said that using energy balance can show good effect which biofuels influence on the environment, while energy efficiency shows the efficiency in the production which is from biomass to biofuels. The writer stated that the energy inputs can be divided into three kind, and there are “agricultural energy” (Rowe, 2007, pg.164), “processing energy” (Rowe, 2007, pg.165) and “transportation energy” (Rowe, 2007, pg.165). Rowe mentioned that reducing the costs and the production of biofuels can improve the biofuels’ energy balance.
According to “Effects on Greenhouse Gas Emissions and Climates Stability” in “Biofuels” by Antony Rowe, the writer noted that not all the corps can produce the same emission. The author reported that there are many way to show the effect of biofuels feedstock production and harvest. Rowe explained the ways is that “land-use change” (Rowe, 2007, pg.171) means that instead of the crop which can only be planted every year people can use “perennial herbaceous species” (Rowe, 2007, pg.172), and in “crop management” (Rowe, 2007, pg.173) producing fertilizer have the biggest effect to climate. The author showed another tow ways is that “feedstock selection” (Rowe, 2007, pg.174) is very important for producing biofuels and how to harvest the crop is also very important thing. The author described that there are something in “life-cycle” (Rowe, 2007, pg.177) which can affect the biofuels.

Summary:
According to “Liquid Biofuels” by Greg Pahl, in the Citizen Powered Energy Handbook (2007), diesel engines and tanks easily lead to the growth of bacteria, which can make destroy the system. The author stated that biodiesel can be a good “heating-fuel additive” (Pahl, 2007, p206), and using biodiesel can get two and three energy than using ethanol. The writer showed that there are three major producers, “large-scale commercial, small-scale” (Pahl, 2007, p209) and individual, which product biodiesel, and there are the large and small different forms “biodiesel cooperatives” (Pahl, 2007, p210). Pahl explained that the large biodiesel cooperative industries were often founded in Widwest, while the small one can be divided into three categories, and there are very small group producer, “bulk-buy” ((Pahl, 2007, p211) and the one which every people can be trained. The author said that ethanol and biodiesel which are produced from plants are the “first-generation” (Pahl, 2007, p215), while the biofuels which are made from cellulose are the second one. The writer mentioned that the second one is similarly to the first one and be produced in many different countries.
The author noted that “straight vegetable oil (SVO)” and “waste vegetable oil (WVO)” (Pahl, 2007, p220) can be used at home, but they need some equipment. The writer reported that because of the flash point, people could not make WVO combust completely, but now Turner discovered a new system which solves this problem by giving a high temperature at the surface of WVO. Pahl demonstrated that people save “$20,000” from the project of WVO.

Summary:
According to “Liquid Biofuels” by Greg Pahl, in the Citizen Powered Energy Handbook (2007), because oil has been reducing by transportation, liquid biofuels will be more and more important in future. The author showed the history of using liquid biofuels, which started form a design named “an early version” which used alcohol by Nikolaus August Otto in the middle of 1800s (Pahl, 2007, p186), and the modern ethanol industry was founded after the oil shocks.
The writer stated that ethanol was better than gasoline, because the oxygen in ethanol could help “combustion process” and reduce the emissions of CO and NO (Pahl, 2007, p189); therefore, ethanol is used more widely than another liquid biofuels. Pahl said that there was a problem of growing ethanol, because of “new coal- fired ethanol refineries” (Pahl, 2007, p191). The author noted that producing ethanol should keep the balance of energy, and a new ethanol named “cellulosic ethanol” was better than ethanol which is produced from corn (Pahl, 2007, p192). The writer described that producing also had a limit, because the land on the earth is not only for ethanol, as a result, many plants were made to use the whole materials to produce ethanol. The author explained that the backyard ethanol is different from the process of ethanol production.
Pahl reported that biodiesel was also widely used in recent year, and Germany, who produced “1.6 million metric tons” every year, was the leader in producing biodiesel (Pahl, 2007, p200). The author stated that people could use “recycled cooking oil” and the fat from animals, and when biodiesel was produced, people should put water to mix (Pahl, 2007, p202). The writer demonstrated that using biodiesel has some benefit, because biodiesel is fit for any engine and have more oxygen; however, biodiese could be used in cold weather.

We watched a movie about a girl, Matilda, last Friday. It was a wonderful movie. Matilda and her family are different from others.
Matilda is different from other children. When she was four years old, she wanted read books. She found a library by herself. When she completed the children’s book, she continued to read other parts. Everyday, she read a lot, while other children played game at this time. When she went to school, she knew more than others. The benefit was that she read books. For example, she could do difficult multiplication only by using head. However, her teacher needed to use a pen. In contrast to other children, it was more for Matilda to insist on what she wanted. She wanted to help teacher to take something, because they could not enter the house. Even though her teacher forbidden her, she still took the toy and chocolate by using her super ability. If it were other children, they might follow their teacher. Matilda was different girl, but she was kind.
Matilda’s family are different from other family. Her parents and her old brother did not look after her. When she was tow years old, she must have a wash by herself. However, other parents maybe help their children. Her father only wanted to how to sell a bad car in a high price, and her only wanted to make her beautiful. When Matilda was six years old, her parents said that she was only four years old. It is impossible for other family. When Matilda’s teacher came to Matilda’s house, her father did not allow the teacher to enter. However, they are happy to see the teacher in other families. This was strange family.
In conclusion, Matilda and her family were different from others. Matilda was brought up in a strange family, she must do everything by herself. However, other children have helps which are from their parents. I was found that the family was strange and the movie was wonderful.
