that the characteristics adult children look for when they begin the search are not necessarily the things that make a difference to the people who are going to move in.
主句,以主语从句加系表结构构成全句骨架,表达核心判断:成年子女寻找的特点与入住者需求不一致
成分推断 · 3 项
- 先扫描整句,排除非谓语动词形式:"look for" 出现在 "adult children" 后,但前面有名词 "characteristics" 和 "adult children","look" 没有跟在主语后直接构成主谓,暂不判定为主句谓语;"begin" 前有 "when they",是从句内部的谓语;"make" 前有 "that",也在从句内;"are going to move" 前有 "who",同样在从句内;"are" 前有 "search",后紧跟 "not necessarily",这是唯一未被从属标志隔开、直接跟在大段主语后的动词形式。
- 确认 "are" 的位置:它位于 "that the characteristics adult children look for when they begin the search" 这一大段之后,该大段由 "that" 引导,整体充当主语;"are" 后接 "not necessarily the things...",构成系表结构。因此 "are" 是本句主句的系动词,即谓语核心。
- 结论:本分句的谓语是 "are",系动词,连接主语从句和表语。
- 查找主语位置:谓语 "are" 前面是一大段由 "that" 引导的从句 "that the characteristics adult children look for when they begin the search",该从句内部有完整的主谓结构,但在主句层面,整个 "that" 从句充当主语。
- 确认主语性质:"that" 引导的从句位于句首(忽略并列连词 "And"),直接作为 "are" 的主语,这是典型的主语从句结构。
- 结论:"that the characteristics adult children look for when they begin the search" 整体充当主句的主语。
- 查找表语位置:系动词 "are" 后接 "not necessarily",再接 "the things that make a difference to the people who are going to move in",其中 "not necessarily" 是副词修饰 "are",真正的表语是 "the things..." 这个名词短语。
- 确认表语性质:"the things..." 与主语 "that the characteristics..." 通过系动词 "are" 构成等同或说明关系,符合主系表结构中表语的定义。
- 结论:"the things that make a difference to the people who are going to move in" 是主句的表语,说明主语所指内容并非这些东西。
时态 · 语态 · 语气
- 时态判定:谓语是 "are",系动词的现在时复数形式,无助动词、无完成体标志(have/has + 过去分词)、无进行体标志(be + 现在分词)、无情态动词,因此判定为一般现在时。
- 语态判定:"are" 是系动词,后接表语 "the things...",构成主系表结构,不涉及主动或被动的施受关系,语态填不适用。
- 语气判定:本句为陈述句,无虚拟语气标志(如 were、should、would 等虚拟形式),无祈使语气标志,判定为陈述语气。
语义说明 一般现在时在此表达客观陈述,说明成年子女寻找的特点与实际入住者看重的东西之间存在不一致,这是一种普遍现象或事实判断。
