The natural teaching method is divided into four stages: in the first stage, teachers talk naturally with students in class, use basic vocabulary and sentence patterns and highlight them. Repeat key words. Teachers help students understand through body movements and visual clues, such as pictures and objects. Students only need to understand and execute short English instructions and make nonverbal responses. It is normal for many students to go through a period of "silence" before they speak. At this time, teachers should be patient and don't rush for success. In the second stage, teachers naturally talk to students, choose to use simple vocabulary and sentence structure, and continue to pay attention to whether students can correctly respond to simple English instructions. In addition, teachers can use general questions, choice questions and Wh- initial special questions, and ask students to answer questions with one or two words or phrases. Students should be able to understand and answer these questions. In the third stage, teachers talk with students in natural and simple language, ask questions with special questions beginning with How, and ask students to explain in phrases or complete sentences to express their views. Teachers should encourage students to express their thoughts and communicate with others in English in real life. In the fourth stage, teachers can continue to use visual AIDS to strengthen key vocabulary. At the same time, teachers can choose a topic or ask to describe a scene to guide students to use English. At this stage, students should be able to talk freely in English, participate in social activities extensively, and be able to reply and discuss problems in fluent English at academic conferences.
