10．If Mr．King doesn't pay for the house before this Saturday，they will sell it to others．（改写句子，句意不变）They will sell the house to othersunless Mr．Kingpays for it before this Saturday．
分析 如果上周六前王先生还没有买房子，他们就会将房子卖给别人．
解答 答案：unless，pays．结合if…not表示如果不，用unless替换，引导的条件状语从句，遵循主将从现的规则，从句主语是Mr．King三单，故pays，故答案是unless，pays．
点评 Unless 的条件句
表示在特定条件下，才决定做或不做一件事，中文用的连接词一般是"除非"和"否则"．如：除非刮台风，否则演唱会将如期进行．在英语中，我们可以用unless表达这个意思，相当于if not．以这个句子为例：The concert will be held as schedule unless there is a typhoon．=the concert will be held as schedule if there is not a typhoon
