After, we are studying and doing project about the problem of English writing from ten items of basic sentence pattern and ten items of grammar type of error for analyze and we choose only fourteen students from klongmorn School. We discover almost article problem because the student are ignore or forget the article but it’s very important to communication and writing. These problems are very simple and easy but we cannot ignore them. Moreover, we should emphasize these weak points in order not to make the same mistake in the future. If we don’t repair the problems its make the student can’t understand and use the problem to the future. From we are checking point of error and learning from this project. We have more knowledge and skill of writing than past that we can use it for study in the future.
