【正确答案】 B

【答案解析】此题属于语法题。rather than 是并列连词，可以连接形容诃、动词、名词、副词、不定式等，其意为“不是这样而是那样”。例如：(1)China's industrialization needs a lot of scientists rather than a few．(2)I prefer to work rather than remain idle．我宁愿工作而不愿闲着。文中此句意思为：老年人愿花时间谈论过去，而不太愿谈及将来，故选项[B] rather than正确。选项[A] better than (比…好)；选项[C]less than (比……少)；选项[D] other than意为“不同于……，除了……”，例如：(1)The truth is quite other than what you think． (2)We missed the last bus so there was no choice other than to walk home．
