TSG meaning “Traditional school grammar”, students often used it on essay, novel, and poem. It improved people’s literacy skill. Such as teach students how to best learn grammar. However, grammar in long time ago, such as the Middle Ages, the grammar show moral dimension, because the language change reflected people’s innate sinfulness, ancient people used grammar to increase their self-interest and to change their status. I have thought grammar that changes, because with the progress of the times, people’s literacy skills have also improved. people can use correct grammar to express their thought. I think the rules of now isn’t very good, because it limit on our classroom rather than our life, we also need to consider our live to improve our literacy.
