The topic of this composition is guidance material, not a propositional composition. As long as we carefully analyze the guidance materials, it is not difficult to find that the object involved in the guidance materials is sound. In other words, the writing scope of this composition question is actually "sound". This type of composition can better arouse our thinking and reflect our interest in life, so as to effectively examine our observation, perception, ability to experience beauty, depth of thought and height of understanding. The material tells us in the form of parallelism that different voices have different effects on us. There is such a voice, telling love, responsibility and conscience ... and when you hear such a voice, it will enrich your emotions, purify your mind and enhance your realm ... Look at the topic and pay attention to every word in the topic. "You" means objective existence; "So" is an emphasis, but a concrete reference; "One category" emphasizes quantity; Sound is the main body of the article's description, narration and discussion, which can refer to natural sounds, such as wind, underwater sound and birdsong. It can also refer to the sounds in life, such as car sound, music sound and human voice; It can also refer to the sound without sound. "Custom style" does not require style, but only provides more free expression space in the form of expression. If you write prose (including narrative), you can describe your own experience of listening to a certain sound, describe the sound in detail, and then write out your unique experience and feelings after listening to it. You can also express your feelings while describing it, and the feelings should be true. If you write an argumentative essay, you must first establish how your argument is unfolded, so that you can clearly show your point of view. The subject will demonstrate the meaning and value of this voice and avoid empty comments.
