he had to wait until one of his coworkers came to work and

he had to wait until one of his coworkers came to work and -----him
中间是填find 还是found 呢,
那came to work 又如何解释,难道不能是to work 和 find 并列吗

He had to wait until one of his coworkers came to work and (found) him.他不得不等到一位同事来上班并发现了他.这里came to work和found him同并列的谓语,则and连接 这里的came to work的主语是one of his coworkers one of his coworkers came to work （直到）他的一位同事来上班,这是一个时间状语从句 是came to work和found him都是one of his coworkers发出的动作,现在可以明确了吧 came to work这里的谓语是came,不是to work,因此came和found同是一个人发出的两个过去时态的动作 如果说came to find him那这个人来就不是上班,而是来找他了,与原文意思不符的
