Altogether there are three volumes, each of which is divided into two volumes. The first two are used in the first semester, the third used in the second semester. The course is divided into three stages: the phonetic stage for developing the pronunciation skills and learning common characters, the grammar stage for developing simple communication skills through conversations, and the lexical stage for expanding vocabulary through essays reading, and developing the ability to express themselves. Grammar, words and sentences are put into the real life situations.
