【第 1 段建议】: 1. "lmpact"应为"Impact"（字母错误，'l'应该是'I'）。 2. "Screening Plant"下的"Portable"前缺少"and"（需加上"and"）。 3. "Mobile Demand"应为"Mobile Demands"（单复数错误，需改为复数形式）。 4. "EPCO"应为"EPC"（如果是缩写，需确认是否正确，通常是"EPC"）。 5. "Vibrating scree"应为"Vibrating screen"（拼写错误，缺少'n'）。 --- 【第 2 段建议】: 1. "n mobile crushing station"应为 "A mobile crushing station" 2. "the YG938E69 mobile crushing station" 处应避免重复使用 "mobile crushing station"，建议改为 "the YG938E69 model" 3. "the vibrating screen mobile crushing station" 中的 "the" 可以考虑去掉。 4. "the transportation cost of the call" 中的 "the call" 应为 "the cost" 5. "to ensure the living environment of residents" 中的 "of residents" 可以简化为 "for residents" 6. "not worthwhile" 更常用的表达为 "not worth it" 7. "or a real estate that is dumped" 中的 "a real estate" 应为 "a real estate property" 8. "the advantages of the port mobile crushing station are highlighted" 中的 "port" 可能是错误，需确认是否是 "vibrating screen" 或其他适当的描述。 请更正以上问题。 --- 【第 3 段建议】: 1. "he" should be capitalized as "He". 2. "it can be said that it is an excellent handling expert" should either remove "that" for better clarity or change it to "it can be said to be an excellent handling expert". 3. "so that the flexibility becomes stronger when used," should have a comma replaced with a semicolon, or connect it better to the next clause. 4. "not only solves the problem" should add "it" before "not" for clarity: "not only it solves the problem". 5. "of processing One Ton of Gold Ore?" - "One Ton" should be "one ton" for consistency in capitalization. 6. "to be Our Agent" should be "To be our Agent" for consistency in capitalization. 7. "Demand(multiple):" should have a space: "Demand (multiple):". 8. "brochures, catalogs）" should change the closing parenthesis to a normal parenthesis: "brochures, catalogs)". 9. "Sales Hotlin" is incomplete and should probably be "Sales Hotline". Please make these corrections.
