In another example, "这是我的书" (This is my book), the particle 的 is used to indicate that the book belongs to the speaker. The sentence could be translated to Engpsh as "This is a book of mine."

读 (dú) means "to read" in Chinese. It is a verb that can be used in sentences such as "我读了这本书" (I read this book) and "他正在读那本书" (He is reading that book).
