11．They made up their mind that they______ a new house once Larry changed jobs．（ ）| A． | bought | B． | would buy | C． | have bought | D． | had bought |
分析 他们决定只要Larry换了工作他们就买新房子．
解答 答案B．
once引导的是条件状语从句，根据主句将来时从句一般现在时的用法可知，从句一般过去时，主句应是一般将来时的过去时．句意为：他们打算只要Larry换了工作他们就买新房子．故选B．
点评 过去将来时的概念：
过去将来时表示从过去的某一时间来看将来要发生的动作或存在的状态．过去将来时常用于宾语从句和间接引语中．过去将来时的出发点是过去，即从过去某一时刻看以后要发生的动作或状态．
