【第 1 段建议】: 1. "Vertical Shaft lmpact Crusher" -> "Vertical Shaft Impact Crusher" (capitalization error in "lmpact") 2. "SMP Crushing Plant" -> There's a suggestion that "SMP" could be spelled out for clarity, but this is not a strict error based on the text provided. 3. "MENU" should be formatted consistently if other headings are in a particular style (all caps or title case). 4. "Chatbot" is missing from the list of Languages; if it’s an option, it should be added for consistency with other listings. However, this is not an error based on the current text. 5. The repeated use of "Home" and "Business" in various sections could imply redundant formatting unless intended for navigation, which should be consistent throughout. There are also formatting issues with spacing and capitalization but they do not pertain to spelling, singular/plural forms, or punctuation based on the request. --- 【第 2 段建议】: 1. "congestion, increase the load" - "increase" should be "increased" for parallel structure. 2. "easy to lead to overload" - "easy" should be "easily". 3. "therefore, a reasonable sand making scheme is also one of the main factors affecting the efficiency of sand making." - Consider rephrasing for clarity; it is slightly awkward. 4. "affect the efficiency of sand making machine" - "sand making machine" should be "sand making machines" for consistency in plural form. 5. "affect the production efficiency of the equipment." - Remove "the"; it should be "affect production efficiency of the equipment." 6. "therefore, a reasonable sand making scheme is also one of the main factors" - The initial sentence has slightly repetitive wording. 7. "affect the efficiency of sand making machine" - Change "sand making machine" to "sand making machines" to maintain plural consistency throughout the text. Please make these adjustments for improved clarity and grammatical accuracy. --- 【第 3 段建议】: 1.
