求翻译：10.5委托人如果中途终止合同，咨询工作已经过半，委托人应全额支付咨询酬金；咨询工作未过半者，委托人则应支付咨询酬金的80%，或已预付的咨询酬金不予退还，两者之中取其高者。是什么意思？

10.5 client if she had to terminate the contract and consulting work has more than half, the principal remuneration shall be paid in full consultation; consulting work is not more than half of those, the client should pay 80% of the remuneration of the consultation, or prepaid consulting remuneratio
