Chatting can be a useful method of writing
Nowadays, chatting is as familiar as talking face to face. And sometimes chatting is used for writing class. It can help students to talk easily. So it can improve students’ fluency. But there are some concerns about using chatting in writing class. Some say that even though using chatting can help to improve one’s writing skill, it cannot help to write in the right way. Especially young people who use blogs and messengers more have a problem. “The things that suffer most are spelling and punctuation. They put a comma, not a period, where there is a pause” (Weeks, 2008, Para. 36). Despite these problems, is it a good idea to use the chatting in writing class?
We know the pros and cons of chatting in writing class. It can help to improve writing fluency more easily than any other teaching materials, but students are likely to use words not imprecisely. Therefore we have to find the way to use chatting effectively. There are some conditions to using chatting effectively.
First of all, the students who use the chatting in writing class should not be native students but foreign students. It is a daily event that the native students use chatting with their friends. So the words that they use are easily transformed or shortened. But foreign students do not usually use chatting. They are familiar with using formal words and do not even know the words used online. So it is fine to use chatting in EFL/ESL classes. ”Integrating chat in EFL/ESL can be powerfully motivating and bring enormous excitement to what is generally in a difficult process – learning a language” (Almeida d’Eca, 2003, Para. 3).
Second, to use chatting in writing class one has to be with instructors or teachers, because it is easy for them to correct the words when students write down the wrong one. And instructors can help when students do not use the transformed or shortened words. So the role of instructor is very important. They have to be educated about teaching with chatting.
Third, there has to be feedback or self critique. Instructors have to let the students know about their mistakes and wrong words or grammar. And students have to do a self critique based on the instructor’s advice. Students have to know why they made mistakes and what they have to be careful about when they write. It can help to improve their writing fluency and to use correct words. Eventually students can gain writing skill and objective criticism.
“Traditional ways of thinking and learning are undergoing a sea change” (Guess, 2007, Para. 17). Even though using chatting has weaknesses, it is a very useful method to improve foreign students’ writing skill. When we keep the conditions that we are deaing with, chatting will be an effective way to learn English.

Abstract
The topic of this paper is the crisis of krill living in Antarctica. It argues that we should protect them because krill is a very useful species to maintain the food chain and ecosystem in Antarctica. There are three ways we can protect krill. The first way is that individuals pay attention to the ecosystem in Antarctica and reduce the pollutants from our lives. The second way is that the government reduces the total amount of pollutants and imposes legal controls on the amount of krill fishing for protecting krill. The third way is that environmentalists and environmental associations investigate and watch the ice shelves and species in Antarctica periodically, let people know about the crisis of krill and Antarctic Ocean and convince the governments and fisheries to reduce the amount of krill fishing.

B. Three solutions.
C. Human have to protect not only krill but also all species and ecosystem.
“Krill living in Antarctic Ocean is like a tiny shrimp and it belongs to the animals that make up the zooplankton” (Ward, 2008, Para.1). Krill is smaller than any other species but they are the most plentiful species in the world. “Also krill often are referred to as ‘keystone’ species because they play such an important role for many marine systems” (Howard, 2008, Para.2). Krill living in Antarctica are at the bottom of the food chain and many predators depend on them. “Krill are also believed to be important in removing the greenhouse gas carbon dioxide by eating carbon-rich food near the surface and excreting it when they sink to lower, colder water to escape predators” (Jowit, 2008, Pare.2). But nowadays the amount of krill is decreasing because of some man-made reasons. One is global warming. Global warming makes ice shelves in Antarctica melt and increases the temperature of the Antarctic Ocean. “The ice that is home to the algae and plankton they feed on is melting” (Jowit, 2008, Para.2). So, krill will not be able to survive or they have to move to another place. Another reason is over-fishing. People started to fish krill for many things in human life. “Krill – small, prawn-like crustaceans used in fish feed, human dietary supplements, soya sauce flavoring, pharmaceuticals and even in cleaning Old Masters – are increasingly in demand” (Doyle, 2008, Para.2). And the amount of fishing krill is also increased year by year. So the over-fishing threatens not only krill but also the ecosystem in Antarctica.
The ecosystem can control its constituents by itself. However humans force and confuse the ecosystem. We made global warming and we are even over-fishing krill. Krill are under the double torture of global warming and over-fishing. “It threatens not just krill, but the entire ecosystem that depends on them” (Jowit, 2008, Para.2). We have to stop destroying Antarctica because it is playing a very important role on the earth where we live. There are three ways that we can do better for krill.
All the individuals have to pay attention to the ecosystem in Antarctica and make an effort to help the species in Antarctica, especially krill. Some people do not know what krill is, despite the fact that they use krill products. Krill is not only good for people’s health but also plays a big role for environment. First of all we have to ‘Know’ about krill and how important it is. As we have said above, krill can reduce greenhouse gases on the sea surface and feed up the species that depend on it. As a result, they reduce the bad effects of global warming and maintain the tons of species. It means that krill solve the problems that we made. People are polluting the environment, but krill are purifying the pollution. Second, we have to reduce the pollutants from our lives. The most important thing is ‘reusing, reducing and recycling’. We are overusing resources and dumping a lot of wastes everyday. It causes global warming in the end. So we have to stop dumping and to save resources. There are many ways to save resources. “Turn your lights off, turn your T.V. off, walk to the shop, and buy a greener car” (Waller, 2007, Para.2). Using renewable resources can be another way to save resources and to reduce pollution. We have to reduce the global warming for our environment.
To protect krill and Antarctica, government have to play a big role. First, each government has to reduce the total amount of pollutants per year discharged from its country. It can be possible when the government controls the individuals, factories, farms, cars etc. The government has to make the environmental protection law and to control the amount of resources that they use. The less they use resources, the less pollution is discharged from their country. Second thing that the government has to do is to impose legal controls on the amount of krill fishing. “A holistic, ecosystem-based on approach, where demands on marine resources are managed within the limits of what the ecosystem can provide, is needed to protect marine biodiversity” (Ocean life fading: What can be done?, 2007, Para.17). Even today, krill trawling is not under the application of the law. And fishers are making a new method that is more efficient than the existing method. If we leave the things like this, the amount of krill will keep decreasing. The government is the best system to control the krill fishing. So the government has to pass the bill that can control and manage the krill fishing. Also the government has to keep an eye on the krill fishing and to punish the fishers when they exceed the limited amount of krill fishing. It will be an efficient way to protect krill.
Third, environmentalists and environmental associations have to investigate and watch the ice shelves and species in Antarctica periodically. They have to show the evidence to prove that krill and the Antarctic Ocean are suffering from the global warming and over-fishing. If they can show people the evidences through the investigation, it will be easy to convince people to believe the crisis of krill. And environmentalists and environmental associations have to let people know about the crisis of krill and the Antarctic Ocean. The first step of protecting krill is making the people concerned about the crisis of krill and the Antarctic ecosystem. That is because, in these modern days, public opinion is very powerful, so it can change things. If people come to be concerned about krill and the Antarctic Ocean and they want to protect krill, the government keeping an ear to the ground will obey the dictates of public opinion. Also environmentalists and environmental associations have to convince the governments and fisheries to reduce the amount of krill fishing. The fisheries will not reduce the amount of krill without convincing. Far from reducing it, they will increase the amount of krill, because their priority is the profit. So environmentalists and environmental associations have to convince them. And arousing public opinion and forcing to the government based on the public opinion are also their missions. Eventually, environmentalists and environmental associations can do begging to protect krill and the Antarctic Ocean.
Opponents of protecting krill claim that the amount of krill fishing is not too much to maintain the food chain of Antarctic Ocean. “Scientists say they are monitoring the fishing, but so far the total catch is a small proportion of the population” (Jowit, 2008, Para.4). But the fact that we are concerned about is not ‘now’ but the ‘future’. Even though the amount of krill is enough now, it is decreasing now; in the end, it will cause a bigger problem such as the extermination of Antarctic species, because krill is a necessary species to maintain the food chain. So we have to be concerned about krill and Antarctic Ocean from now on. Also, fisheries claim to be concerned about krill supplies. “Helge Midttun, chief executive of Norwegian-based processor Aker BioMarine, said they were careful not to damage krill stocks, including developing a net around their suction system to stop other species being harvested.” (Jowit, 2008, Para.9). But their instruments such as their nets are developed and improved. We can find it through the annual amount of krill fishing. The amount of krill fishing keeps increasing year by year. It shows that the fisheries are fishing krill in an unsustainable way. If we let them fish krill as they do now, the extermination of krill is ineluctable consequences.
In conclusion, krill is a very useful species living in the Antarctic Ocean. Krill is useful to maintain the food chain in Antarctica and krill can remove CO2 on the surface of the Antarctic Ocean. So, krill is necessary in the Antarctic Ocean. But the amount of krill is decreasing because of the global warming and over-fishing. Therefore we have to make efforts to protect krill. Individuals have to pay attention to the ecosystem in Antarctica and to reduce the pollutants from our lives. The government can reduce the total amount of pollutants and impose legal controls on the amount of krill fishing for protecting krill. Also, environmentalists and environmental associations have to investigate and watch the ice shelves and species in Antarctica periodically, to let people know about the crisis of krill and the Antarctic Ocean and to convince the governments and fisheries to reduce the amount of krill fishing. Moreover we have to protect not just krill but all species and their ecosystem in the whole world.

Juhye Choi/EAP2-A/June 2, 2008 Fluency exercise #3
If woman has a plan to go to India, she should be careful because in India, to expose her legs is a taboo. When I was traveling to India, I had to wear a long skirt or pants, even though it was extremely hot. Also when my friends and I took a bath in the public bath place, we had to wear our skirt. When one of my friends rolled her pants up, some guys came to her, pointed at her and shouted to her. So she had to pull down her pants immediately. I could not understand it because they allow exposing the bust. And they think that legs are more sexual than the bust. It is so different from Korea. In Korea a woman can wear short pants or skirt, but to expose one’s bust is not good. It was a very mysterious and weird experience, and I still cannot understand their thought.

The decreasing of krill and how we prevent the problems
According to ‘Crucial resource at risk’ Doyle said that krill is smaller than any other species but they are the most plentiful species in the world. Krill living in Antarctica is on the bottom of the food chain and many predators depend on it. But the amount of krill seems to have decreased because of its usefulness. After humans found out about krill’s usefulness, people started to fish them more and more. Against this concern, the fishers claim that they are fishing krill in a sustainable way. Another problem is that an amount of krill is threatened by global warming. It is a big problem that we do not know clearly how global warming affects the amount of krill.
If the amount of krill decreased, many species at the top of food chain are threatened, and this threat is connected to the crisis of environment. We have to know clearly the reason krill has decreased in order to prevent it and protect it. First of all, we should make clear the reason krill has decreased.
The first reason krill has decreased is that humans are over-fishing it. Nowadays krill is using many parts of human life. We use it for food, pharmaceuticals, fish’s feed, colorants etc. After people found out that fish oil is good for health, people wanted more krill because krill is very good material for fish oil. And people made new nets and vessels that made the fishing easier. If we keep fishing krill more and more, eventually we will break down the food chain in the ocean and environment.
Another reason is global warming. We cannot exactly know how global warming affects krill and the food chain. But we can predict it through the strange phenomena that we see nowadays. For example, high temperature makes algae on the surface of the ocean; it blocks sunlight. Without sunlight, oxygen in the water decreases. Finally global warming makes krill unable to breathe and kills it.
We have to find how we can protect krill and species. We have to supervise krill fishing and limit the amount of krill that fishermen can fish in a year. And we must change our thought about global warming. Global warming is definitely more serious than we had thought. The first victim will be krill or any other species in the bottom of the food chain; eventually the last victim will be human. So, to protect krill is to save human nature and environment.
We have to remember that human being is on the top of the food chain. The species becoming extinct will be the human being. Therefore we have to keep an eye on the environment where we live and try to protect it.

What we can do to prevent ice shelf eroding
In the article ‘Antarctica’s Wilkins ice eroding at an unforeseen pace’ Peter N. Spotts said that ice shelves in Antarctic are melting rapidly and the reason of melting reads into the global warming. Even though the melting is rapid, it is not that serious as yet. But if we leave the matter as it is, things will get worse. And there are two opinion of ice shelf melting. The one is that global warming causes the melting of ice shelf, and makes the sea level goes up. The other one is that the ice shelf is stable enough and the melting sometimes appeared in the past, but nothing happened. Therefore we have to figure out the reason of ice shelf melting, and it can help to predict the consequences of ice shelf melting.
The most important and immediate thing we have to do is to find the exact
reason of ice shelf eroding. Some of scientist claims that the ice shelf eroding is just a seasonal thing that we saw in the past times like the Roman era and Medieval Warm Period and it does not a big deal. But they are passing over something can cause the serious and miserable thing in the world. Even though ice shelf eroding can be seasonal thing, it is not an established view now. Therefore we have to make clear the reason of ice shelf eroding.
If something shows the same phenomenon, it can be caused by another reason. It is true that ice shelf eroding appeared in the past times, but now things are changed. Air pollution is serious, the temperature goes up and it becomes the reason of ice shelf eroding. It is the rapid change in the whole world and it is caused by human nature. Humans wanted to develop their society and industry at a short time, it leads the pollution. So, now we face the bad consequences of the rapid development.
Ice shelf eroding is one of the bad consequences that we caused, so we have to correct things before they get worse. First of all, we should figure out the reason of ice shelf eroding. We have to focus on the process that ice shelf eroding changed, and we have to find out the different factors that we could not find. We can find the reason of ice shelf eroding through we analyze the factors of ice shelf eroding. We can prevent the worst situation when we find out the exact reason.
The bad consequences that we made can be changed by us. If we start to fix it, it can be straitened immediately. Therefore we have to observe the change of ice shelves, analyze the factors, figure out the reason of ice shelf eroding and try to prevent the bad consequences of ice shelf eroding like rising of sea level. This will be the best thing that we have to do for our environment.

In the article ‘Antarctica’s Wilkins ice eroding at an unforeseen pace’ Peter N. Spotts said that ice shelves in Antarctic are melting rapidly and the reason of melting reads into the global warming. Even though the melting is rapid, it is not that serious as yet. But if we leave the matter as it is, things will get worse. And there are two opinion of ice shelf melting. The one is that global warming causes the melting of ice shelf, and makes the sea level goes up. The other one is that the ice shelf is stable enough and the melting sometimes appeared in the past, but nothing happened. Therefore we have to figure out the reason of ice shelf melting, and it can help to predict the consequences of ice shelf melting.
