【第 1 段建议】: 1. "lmpact" should be corrected to "Impact" (lowercase 'L' vs. 'I'). 2. "produc" should be corrected to "production" (incomplete word). --- 【第 2 段建议】: 1. "sa" appears to be an incomplete word and may need clarification. 2. "sand stone production line" should be "sandstone production line" (should be one word). 3. "the purchase of such a production line by the factory enterprise" - "factory enterprise" is awkward; it may read better as "manufacturing enterprise" or simply "factory." 4. "The wind is very simple" - could be a typographical error; context is unclear. 5. "the production line runs very little" - awkward phrasing; consider rewording to "the production line runs smoothly" or similar. 6. "Such a production line of people's components can get rich returns" - awkward phrasing; consider rewording for clarity, such as "Such a production line can yield significant returns for its operators." 7. "the price of sand and gravel crushers is very affordable, which makes the price of the production line within the tolerance of most companies" - may be clearer as "the price of sand and gravel crushers is very affordable, making the overall cost of the production line acceptable for most companies." 8. "the product quality is very good, the production line will not produce harmful substances during the operation" - consider splitting into two sentences for clarity, i.e., "the product quality is very good. Additionally, the production line will not produce harmful substances during operation." 9. "the production line noise is very small, it will not cause harm to people's ears" - should be split as: "the production line noise is very low. It will not cause harm to people's ears." --- 【第 3 段建议】: 1. "ction"应为"action" 2.
