Question

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

Answer

B

【解析】

试题分析：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。故答案选B。

考点：考查时态和语态。

【名师点睛】考查过去将来时。一、"would+动词原形"表示过去将来时"would+动词原形"构成过去将来时，常表示根据计划或安排即将发生的事。例1：He said he would come to see me.他说他要来看我。例2：He told me he would go to Beijing.他告诉我他将去北京。二、"was /were+going to+动词原形"表示过去将来时"was /were+going to+动词原形"也可表示根据计划或安排即将发生的事。例1：She said she was going to start at once.她说她将立即出发。例2：I was told that he was going to return home.他告诉我他准备要回家，本句中关键词为made up这一过去时态，这是在过去计划将来做某事。因此，用过去将来时。
