Biodiesel


In Seth Gudmunson’s article, “Big on biodiesel,” he states that biodiesel will have less of Carbon dioxide, which it is 78%. It gives better lubricity to the engines and it makes the engine clean. It produces cleaner smell and the smoke will not bother people and farmers around. It will improves soybean market from which biodiesel is extracted. This will benefit farmers since the price of soybean would increase.
Do you have a farm? You want to get a better life? The people and workers try to improve their life by using great things. Biodiesel is one of petrol diesel sources. It has less dangerous than other diesel. Biodiesel is containing from vegetable and animals oil. The biodiesel should be used because it helps to reduce the pollution, helps to reduce the oil dependency, and helps increase farmers’s income.
At first, the biodiesel helps to reduce the pollution because it uses diesel engines which it is health for environment. In Gudmunson (2005) writes “biodiesel results in a 78% reduction in Carbon dioxide emissions”(pa.13). It has little emission of Carbon dioxide. In addition, most biodiesel uses lean fuel. It contain with little or no toxic emission such as sulfur, which is carcinogenic. Also, it makes the engine of cars cleaner. The smoke that is come from the exhaust in cars is clean not like other diesel. Therefore, it is good for environment because it has less dangerous chemical gases.
Second, biodiesel reduces the dependency on oil imported because it is mostly made from natural sources such as plant .this will have a big benefit for establishing peace in the world. All countries will be able to produce this kind of fuels without the dependence on foreign petroleum. Especially the countries that have hug crops of vegetable that workers use it to make biodiesel. Therefore, it is good for many countries because it leads them to work and get the crops from themselves.
Finally, biodiesel helps farmers because it costs fewer than other petrol diesels and it protects their product. There are many farmers use it for their engine. Many of gas can affect the plant and that cause of the death for plant. Biodiesel is the big fact for increase the production. It is cleaner than other gases such as petrol diesel. Gudmunson (2005) writes “ fewer emissions make working around the farm easier”(p13). Many of gas can affect the plant and that cause of the death for plant. Therefore, biodiesel helped farmers to increase their production because it has less dangerous foundation than other gases.
In conclusion, biodiesel is kind of diesel which it helps many people. Biodiesel will improve their environments and will help farmers to increase their production. It is useful during these days until the workers and companies find better source than biodiesel. Therefore, it is very good to people .biodiesel is one a good source that people find. The oil is caused to pollution. . Biodiesel is less dangerous than diesel. Many farmers are dependent on oil. Therefore, it is very useful gas and the people should use it.

TOEFL TEST

Today, most of American university in U.S. order TOEFL test as a one of their requirements to complete the American university because the TOEFL test is general test about English language. TOEFL tests some part of English skills that people use. Many students feel bad because they are caring about test. Also, if they do not pass the test they can complete their education in some university in US. The students have to study hard to get good grade to go to university. The TOEFL should not be used for American university admission because it does not use all English skills, it does not match with university work, and it is not fair for some students.
At first, the TOEFL test does not use all English skills. There is no speaking part on test. Many international students can speak very well but there is no part on test like conversation so they can not show their skills in this section. Also, there is no writing part on test. It can effect in students who are good at writing essay. Therefore, TOEFL is bad for international because some of them can speak and write very well but there is no section for it in test.
Second, TOEFL test does not match with university work. There is a big different between TOEFL class that students learn about TOEFL and university work. In university the lecture much bigger than TOEFL class such as science class. On other hand, reading is other problem because in university they take huge number of pages but in TOEFL class they take a few pages. They can read quickly because they have limit time. Therefore, it is bad for students because it does not grade their time.
Finally, TOEFL is not fair for some groups. There are many requirements to do to the TOEFL test. Many people can not pay the test application fee such as poor because they do not have enough money. Also, the students can not talk by the way that TOEFL test use it in grammar section such as the form of grammar part. TOEFL is not general English speaking for all people because it is too difficult for non native speaker. Therefore, it is not acceptable to all people who study English.
Opponents of TOEFL test claim that it is easy for school to read the score but that is not true score. It does not give students real level of English because the test is multiple choice such as guessing. The students have 25% chance to get right answer and there is more chance for answer if you move out one answer. Therefore, it is not good for students and because they do not get real score.
In conclusion, many students have kind of problem in some part of TOEFL test. Also, it is difficult for people to talk like TOEFL ways. It is not real English language to talk with. The students have to work very hard to pass the test. It is difficult for many students to pay for test. Therefore, The TOEFL test should not be allowed for international students.

Biodiesel
For a better environment, for a healthier life, for better engines and a good smells, for less dependence on petroleum, biodiesel makes part of the solution. The people and workers try to improve their life by using great things. Biodiesel is one of the energy sources that can be used in engines for truck and cars, it can also be used to produce energy for houses and industries .it may not be an ultimate solution for petroleum alternatives but it will solve in part the problem of limited petroleum supply in the world. In ‘Kiline Study: Biodiesel No Silver Bullet for Crude Crisis” the author states “Biodiesel may not be the ultimate solution to the world's fuel problem, but it is an important part of the solution set,"” (Agashe, 2006, Para 5). It has many advantages over other gases. Biodiesel should be used because it helps the farmers, it cheaper than petroleum, it is good for engine, and it helps the environment Bodiesel (2006) explains “Biodiesel is a domestically produced, renewable fuel for diesel engines derived from natural oils from soybeans, canola and sunflowers and animal fats” (par 6).the first engine of biodiesel as a kind of diesel established in 1898 in Paris (Yokayo biofuels, n.d.). In” Biodiesel” the author argues “Biodiesel was introduced in South Africa before World War II to power heavy-duty vehicles.”(n.d., para4). The biodiesel was stop but it return back before world war two and they were use it for big and weighty vehicles. in” Biodiesel” the author argues “Additional biodiesel could be derived from aquatic plants such as microalgae .This resource has the potential to be able to supply 50% or more of the U.S. diesel market” (n.d. ,para3) . this resource which is called micro algae is kind of plant and it is grow in the sea. Also, the U.S can produce 50% or more from that resource. biodiesel is not 100-percentage replacement of diesel. On the other hand ,biodiesel has two kind of diesel, which they are, call B5 ,and B20. B5 biodiesel which is contain of 5 percentages of plants and animal oil. “A Look at Green Fuels” said B5 biodiesel is mix of 95 percentage of petro diesel and 5 percentage of plant and animals oil. In addition ,the other kind is B20 biodiesel, which contains 20 percentage of biodiesel, and 80 percentage of petro based diesel.
At first, biodiesel helps farmers because it has less chemical substance than other gases. Many of gas can affect the plant and that cause of the death for plant. The gases for engine and machine that farmers use it for their farm it can be the big risk on their product. Biodiesel is better gas to use to save the plants; it is made in part from plant sources. In addition, the major crops that can be used to make vegetable oils for biodiesel are corn, sunflower, canola and soybean. Therefore, biodiesel will open a new market for farmers it will increase the demand for raw materials, farmers would have to grow more crops and this will benefit both the farmers and the industry which manufacture harvesting and patenting machines. In “Kilned Study: Biodiesel No Silver Bullet for Crude Crisis” the author claims “It provides farmers with a new market for their crops and holds the promise of high profits for food conglomerates and other members in the value chain” (2006, para 6).Soybean and crops are not limited for the food industry but can be used for producing biodiesel which is a totally new market for farmers. This will help increase their income and raise the value of such crops. Farmers use the biodiesel for planting and harvesting crops that will be processed into biodiesel so farmers are the first consumers for biodiesel. Therefore, biodiesel is good for farmers. It can help them to increase their product because it has less dangerous resource than other petroleum.
Second, biodiesel is cheaper than petroleum because it can be made from almost any vegetable oil, waste oil from restaurant fryers, tallow, and lard and waster treatment plants. The vegetable and animal oil make the prices of biodiesel is cheaper than other diesel which is 100 percent petroleum based. Also, production in local area gets better prices than imported diesel from other countries. Robinson (2005) “Gordon Petty with Ritter Oil Co. Says:” if crude oil stays at $70 a barrel plus then biodiesel has an advantage”(para3). Currently petroleum prices are hiking because of the conflicts in areas where it is produced and because of natural disasters like what happened in Florida last year, when the hurricane catethrina hit all the oil refining industry stopped. Thus biodiesel is enjoying a short-term price advantage over petroleum diesel. Therefore, it is good diesel by its price because it has many sources to make it. Third, Biodiesel is good for engines because gas engines use ignition whereas with diesel engines no spark plug is required diesel engines are far better than gas engines. Diesel engines are simple, efficient and robust. When comparing biodiesel to petroleum diesel, biodiesel was found better for engines because it gives the engine many benefits. In Foyston (2006) writes “Biodiesel lubricates engines better”(para1). It is good benefit for engine, which it gives the engine easy movement and good grease. In Foyston (2006) writes “most users report no difference except that engines seem smoother and exhausts smell sweeter”(para1). There is no bad smoke in the air and it makes the engine less loudly than other petroleum. Also, it makes the engines soft. Rausch (2006) claims “the biodiesel makes its mark is in its ability to clean an engine and increase fuel efficiency” (par 5). Biodiesel is able to make the engine clean. Also, it can raise the competence of the engine Thererefore, it is better for engine and it has many benefits to the user since the engine would run more miles same than a petroleum based diesel engine.
Finally, Biodiesel helps the environment because it can reduce the emission of carbon dioxide, which that makes better environment than other diesel. In Gudmunson (2005) writes “biodiesel results in a 78% reduction in Carbon dioxide emissions”(pa.13). It has little emission of Carbon dioxide It makes less carbon dioxide than other diesel. Biodiesel it contain with little or no toxic emission such as sulfur, which is carcinogenic. Biodiesel mostly from natural source, which it is better for environment. Therefore, it is good for environment because it has less dangerous chemical gases. Opponents of biodiesel claims that biodiesel is not a good substitute for the petroleum based diesel. In Bodipo-Memba (2006) writes “notoriously poor-performing cold-weather fuel. Below 50 degrees, the fuel begins to form wax crystals that can cause the engine to run rough”(para19). In fact, this problem can only appear during clod weather and for a limited time in the year. However, to avoid the crystallization of biodiesel we can blend it with petrol diesel or we can install a tank heater. In the future, there might be some additives to biodiesel like a chemical substance to keep biodiesel in fluid form at low temperature.
In conclusion, biodiesel is kind of diesel will help many people. It will improve their environment and will help the farmers to increase their production. It is useful during this day until the workers and companies find better source than biodiesel. It has good price than other diesel. Most of countries who use it they made it locally. Agriculture and plant with the improvement of biotechnology farmers will increase their production of crops and yield of oil extracted. Therefore, biodiesel may become an important alternative of petroleum and may replace it forever. Therefore, it is good kind of diesel, which helps people and improves their life.

Evaluating teachers

Did you ever evaluate your teachers? Do teachers want to know about their reaction in class? Teachers are the important column in the schools. Teachers are most people that can make better life. Teachers are second parents for students. All people need their help. The students should evaluating their teacher to help them to know about their work, to make teachers work hard, and to give parents information about teachers personality.
At first, evaluating teachers helps them to know about their work. Many of teachers think they select right way at their work. Moreover, evaluating new teachers can help them to change their ways to be better. Steiny (2006) tell us “that makes comment on teachers get better result “p d2.they can improve their ways of education by evaluating. Since teachers get evaluating they see which part of evaluate is a weak. Because of evaluation the teachers can change their benefits from bad to good. Like if class is bore they can make a joke to refresh class mood. Therefore, it is important for teachers to do evaluating which help them to do better work.
Second, evaluating makes teachers work hard. Teachers have many ways to improve teacher’s skill. Work hard and prepare for class and make good role lead to successful in the work. In ‘college of teachers must find way to evaluate refugee teacher: court” states ‘teachers need to have good political and good experience to get great job’. Makes good deal with students and help them for studying and doing their homework. Teachers have get students from their time if they have during at school to teach them if they confused about class. Therefore, make a control on class from the teachers lead to great work.
Finally, evaluating teachers give parents information about them personality. It is possible for teachers to take care for large number of students like primary school. So evaluating can show students parents good look about teacher’s personality. The parents can see the teachers work and class work. Also the parents can see the level of their sibling if they do fine or not. Therefore, parents can see the level of teachers by evaluating.
In conclusion, evaluating teachers is the best ways to make them work hard. Teachers can see all their work in the evaluation paper which they give it to student. Doing hard work lead students to successes in their education life. Also student’s parents see the summary of teachers work. Therefore, evaluating is very important to teachers which is helping them to do better work.
