please help me to correct the essay, thank you.): Topic: Some people believe that university students should pay all the cost of studies because university education only benefit the students themselves not the society as a whole. To what extent do you agree or disagree? Some people believe that university students should pay all the cost of studies, because the country get noting from these student, and it will benefit to the country’s economy. In my opinion, they are dead wrong, the reason follows: First, university education not only benefits the students themselves, but also benefits the society. The engineers, workers in factory, teachers in school, doctors in hospital, servant in government, and lawyers, scientists, businessmen, etc, many of them are the university educated, they are all serve for the society, benefit the technique, education, science, etc, benefit the society. Second, if university asks students for all cost of their study, and it will be a big money for many common family, many students will not go to university because their family can’t afford it, on one hand, the students lost the chance to get more knowledge and skills, on the other hand, the society lost many good server who may do a lot to the society. Third, there will be little chance for the poor family to change their situation because they can’t afford the cost of university to get knowledge and skills for better life, even sometimes, government or society have to give them some money to maintain them. Fourth, the poor will always have little chance to get good education, they will get poorer and poorer, inversely, and the wealthy will get richer and richer because of good education, and this will result in society polarization, social would become unstable, even be at war. All in all, I disagree that students pay all the cost of studies in university, to short term, the government seems to benefit, but, in the long run, it is much harmful to society.

INTERNET OR UNIVERSITY (IELTS writing practice, thank you for your correction) Topic: Many people use distance-learning programmes (study material post, TV, Internet, etc.) to study at home, but some people think that it cannot bring the benefit as much as attending college or university. To what extent do you agree or disagree with this opinion? With the advent of technology, it comes true that we can use distance-learning programmes (study material post, TV, Internet, etc.) to study at home, but some people think that it cannot bring the benefit as much as attending college or university. In my opinion, although there are a great many of information and knowledge in the modern programmes, material post, TV, Internet, that could bring lots benefit to us. But, firstly, they also contain many undesirable information (obscenity, violence, etc), especially for teenagers, it might cause a bad influence to their proper development because they are too young to have enough self-control. Secondly, it is easy to get distracted when studying use internet, TV, etc, because there are too many things and information, which will be easy to attract their attention, like sports news, QQ, advertisement, etc. In addition, using distance-learning, it means you may learn from the virtual world, you cannot talk to real person face to face, it may make you and the real world become alienated, make you poor of communication. With the comparison, the advantages that study in university or college are follows: First, teachers will give a hand if they need, not only in study, but also their life. Second, the knowledge or information that they will be learned in university or college have been choice seriously which will benefit greatly for the students. Third, studying university or college is good for the students’ concentration on their class and study. Fourth, they could get many friends, classmates, schoolmates, etc, that will benefit in their future life. In conclusion, as far as I can see, although distance-learning programmes could give us some knowledge conveniently, but the most effective way of study is still the traditional method, study in university or college.

IELTS writing practice （thank you for you correction, make it more smooth and better） Topic: Some people think that the government should decide which subjects students should study at the university, while others think that students should be allowed to apply for the subject they prefer. Discuss the two views and give your opinion. After the students finish their high school classes, and prepare for university studying, they will face an important issue, which subject would they learn in university? Some people said, students should be allowed to apply for the subject they prefer, but the other argued that the government should decide which subject students should learn at the university. They said, it will meet the country’s needs, and also will be better for the students to get a good job after they graduate. But for my part, things are not so. One hand, the subjects that government decided will not always meet the needs when the students graduate after 4 year, because everything moves so fast. In the other hand, if they study the subjects that they do not like, there will be no interest for them to further study, and no creativeness for their future work and they will go banal. If the students be allowed to decide their university’s subject according to their interests, things will be better. Firstly, they will have more passion and willingness to learn more about the subjects, there will be more creativenesses for them, and they will do better in the future work. Secondly, the interests of the young are likely the same to the needs of the country, because the young always have the curiosity to the things which be born just now and likely be large demand in the future during the development. Because the country and the young are in the same time, in the same condition, they will always be coincidental about the needs and the interests. In conclusion, let the students, the young, themselves decide what subject they are likely to study in university, it will be benefits for both, the government and students. There is no need for government to decide the subjects of students’, and I hope that the government should give them some advice about subjects rather than the decision.

Geophysics_1 Thanks For your Correction Geophysics is an economical and efficient way for prospection. It is a indirectly method of geological exploration, which use the physical characteristics of stratums, rocks and minerals to prospect or predict the information underground. Geophysics based on knowledge of physics, like theory of mechanical wave, magnetic field, electrical field, electromagnetic field, gravitational field, etc. So the main method of geophysics involved 4 categories: seismic prospecting, electrical prospecting, magnetic prospecting and gravitational prospecting. Seismic prospecting is the most common method of geophysical prospecting, which based on the reflectivity of lays and seismic wave velocity in stratum, rocks, soils and minerals. It can be divided into 3 processes: field data acquisition, data processing and data interpretation. When the work is on in the field, seismic wave would be excited by pound or explosion in ground, and the seismic wave will spread underground through different ways, when the different lays comes, because of the seismic wave impedance differences, the seismic wave will be reflect back to the ground, and then we can receive the reflecting wave by detector that have be laid, because of the spread time(the time seismic is excited to reflected wave be received ) is easily to be known, and the stability of lays in same or adjacent regions, the velocity of wave will be known roughly in the first. Then we come to the second step, data processing, using seismic wave propagation theory, the basic principles of seismic exploration , various methods of signal analysis and processing, we will get more accurate seismic , seismic wave velocity profiles and other outcome data information. Then the third step is interpretation, which use the Seismic wave propagation theory , the principle of the method of seismic exploration , geological , logging, drilling and other geophysical data , by experienced professionals to conduct a comprehensive analysis of the seismic data, seismic profiles and data to remove the illusion of shape and inferred stratigraphic distribution structural shape.

Geophysics_2 Thanks for your correction Electrical prospecting based on resistivity difference between different stratum, rocks and minerals, which is usually used to look for water underground; magnetic prospecting based on the differences of naturally magnetic in different rocks and minerals, which is usually used to look for metallic mineral deposit; gravitational prospecting based on Changes in the density of the gravitational field caused by a wide range of differences to the Surroundings, which is usually used to look for large geological structure.
