This is not a grammar book; this is a writing book. However, good writers should be able to talk about grammar. Then they can talk about their writing. If you know some basic grammar terms, you can learn how to write correct and interesting sentences more easily. You can understand, talk about, and ask questions about the grammatical mistakes you make in your writing, and you can correct them more easily. At the same time, it is important to develop a "feeling" or intuition about English grammar: you can do this by exposing yourself to English. Read English stories, magazines, and web pages. listen to English song; watch English movies; have conversations in English.
