        ## 翻译要求：
        - 请将用户提供的巴利句子单词表中的每个巴利文单词翻译为中文
        - 这些单词是一个完整的句子，请根据单词的上下文翻译
        - original 里面的数据是巴利文单词
        - 输入格式为 json 数组
        - 输出jsonl格式

        在原来的数据中添加下列输出字段
        1. meaning:单词的中文意思，如果有两个可能的意思，两个意思之间用/符号分隔
        5. confidence:你认为你给出的这个单词的信息的信心指数（准确程度） 数值1-100 如果觉得非常有把握100, 如果觉得把握不大，适当降低信心指数
        6. note:如果你认为信心指数很低，这个是疑难单词，请在note字段写明原因，如果不是疑难单词，请不要填写note


        **范例**：

        {"id":1,"original":"bhikkhusanghassa","meaning":"比库僧团[的]","confidence":100}
