例83　At the same time these computers record which hours are busiest and which employers are the most efficient and which employees are the most hard-working, allowing personnel and staffing assignments to be made accordingly and the distribution of goods to be arranged effectively.

【结构分析】此句话有两个并列句，主语是these computers，动词是record，宾语是并列的宾语从句，两个which都是并列宾语从句，allowing...是分词状语，做结果状语，后面两个不定式to是allow这个词的固定搭配，做宾语补足语。

【亮点回放】此句话的亮点在于有两个个超级并列的which，做宾语从句，而且分词状语特别长，后面两个to do用得很巧妙，两个个宾语从句配上分词短语，一气呵成，很和谐。

【核心词汇】

at the same time　同时

【参考译文】同时这些计算机记录下哪些时间是最忙的，哪些经理工作效率最高，哪些员工最努力，这样就能相应地做出人员人事安排，而且让物流变得更加有效果。
