W9T2: Difficulties in writting

One example of the difficulties that I faced in my engineering class is that my notes are often written in improper English. I feel that it affects me greatly whenever I revise my notes. There are times when I am confused about some of the physics concepts because I have trouble figuring out what I am explaining in my notes. In order to resolve this problem, I have decided to summarize my concepts in point form rather than writing in improper English. I believe this will enable me to understand the physics concepts much more effectively. I think I will make it a habit to write a summary from now.

Another difficulty I faced in my engineering class is that I have difficulty in expressing in written form. I will make many tense errors that will confuse my reader. For instance, I will describe the PAP governments by writing “The PAP government is …”. The correct sentence should be “The PAP governments are …” making such error confuses my marker as they will assume that I am referring to a particular PAP government when I am referring to the whole PAP. In addition, I also make careless spelling errors in my Singapore Studies module. In my recent test, there are a few spelling errors in my essay pointed out by my tutor, this gives her a bad impression of my essay and that marks will be deducted due to the poor language expression. Thus, I should read more articles and novels to improve my English language. Furthermore, I can visit ITSELF to do some practice on my grammar errors. By improving the standard of my English, I can certainly score better grades for my other modules.

WT3- Summary (Make solar energy economical)

The sun is the largest power source found on Earth. It gives out infinite amount of energy called the solar energy. Advantages of using solar energy are, it does not produce any pollutant to the environment, it is free to use and it can be used to generate energy from fuel cell. Sunlight produces energy to boost the electrolysis of water to generate a larger amount of energy. This can help mankind save a large sum of money to generate that much of energy. Unlike fossil fuels, it will deplete and cause pollution to the environment. This proves that solar energy is a better choice. In order for solar energy to be more comparable with the cheaper fossil fuels, engineers need to find ways to widespread solar energy; for example to reduce the cost of generating solar energy and to increase the rate of generating solar energy. Enhancing the quality of the solar cells is likely to succeed. Furthermore, through research and develop we are able to find new materials that could reduce the manufacturing price. The present price of the materials to generate solar energy is very high because it must be pure. If the material is not pure enough, it may not generate as much energy as compared to the pure material. An engineer also has to find new ways to hold and accumulate solar energy due to the changing weather condition. It is impossible for sunlight to be transmitted all times. Solar energy is seen as an important energy resource in the future.
