以下是代码中文案中发现的错误点： 1. **单复数误用**: - "maintenances" 应改为 "maintenance" (维护是不可数名词). 2. **拼写错误**: - "offer" 应改为 "offered" 在句子 "SBM actively offer two transformation schemes to the customer." 中应为过去时. - "staffs" 应改为 "staff" 在句子 "designated SBM's staffs to take related roles" 中. 3. **标点错误**: - "built an environmental industrial park" 句子中 "environmental industrial park" 前缺少逗号，应为 "built an environmental, industrial park". - "3.6 million tons of high-quality aggregate every year." 可以考虑将年份前加一个逗号。 - "its schemes can help customer save over 1 million yuan" 中 "customer" 应为 "the customer"。 - "the construction period can be put on schedule at least 1 month in advance" 应增加 "by" 前缀服务于完整的表达：“the construction period can be put on schedule by at least 1 month in advance”。 - "On high-quality aggregate production, SBM is experienced." 可以考虑用句号替换分号，在“experienced”后加上句号。 请根据以上建议进行相应的修改。
