2. Liveliness: Another obvious feature of oral expression is liveliness. In the process of speaking, people often use various gestures, expressions and tones to enhance the effect of expression. This vivid expression can make the audience understand the speaker's meaning more easily and enhance the audience's impression.
3. Communication and interaction: Oral expression is an expression that emphasizes communication and interaction. Different from written language, spoken language often involves direct dialogue or live speech, so the speaker needs to communicate with the audience in real time to ensure that what he says is understood correctly. In the process of communication and interaction, the speaker also needs to ask questions in time to promote the participation of the audience.
4. Natural language: Another major feature of oral expression is natural language. In oral expression, people often use some commonly used phrases and oral expressions to express themselves. However, this does not mean that formal grammar and vocabulary are not needed for oral expression, but that language should be kept natural and fluent under the premise of following grammar and vocabulary norms.
5. Moderate expression of emotion: In oral expression, moderate expression of emotion is also a common expression. Because there is direct interaction between the speaker and the audience, properly expressing some emotions can make the speech more sincere, but over-expressing emotions will make the speech appear exaggerated and unnatural, which is not conducive to conveying effective information.
6. The application of oral English in academic papers needs to be handled with caution. Although colloquial language can make papers easier to understand, excessive use will lead to the loss of academic rigor and refinement.
