Weak reading is an essential part of English intonation and pronunciation training, and is widely used in language teaching and learning materials.
There are four types of intonation in English: falling intonation, rising intonation, level intonation and climbing intonation.
Types
The function of intonation is mainly to express the attitude, emotion and intention of the speaker, and help to distinguish the meaning of the same words and sentences. For example, when we want to express a question, we usually use rising intonation; when we want to express a command or request, we usually use falling intonation.
