"in order that" 是一个复合连词,意为“为了;以便;目的是”,用于引导目的状语从句,强调主句动作的“目的”或“意图”,即主句的行为是为了实现从句所述的结果。
1、 引导目的状语从句
从句通常位于主句之后,说明主句动作的“目的”。为了体现“目的性”,从句中常用情态动词(如 can/could, will/would, may/might, should 等),表示“可能性”“意愿”或“预期”。
例1:He studied hard in order that he could pass the exam.
(他努力学习,以便能通过考试。)
例2:She left early in order that she would not miss the train.
(她早早出发,为了不赶不上火车。)
例3:We turned down the music in order that the baby might sleep better.
(我们把音乐调小,以便宝宝能睡得更好。)
2、 与"in order to"的区别
"in order that" 后接从句(需要主语和谓语),而 "in order to" 后接动词原形(不定式,逻辑主语与主句一致)。
对比:
He studied hard in order to pass the exam. (不定式,主语一致:he 既“学习”又“通过考试”)
He studied hard in order that his sister could use his notes. (从句,主语不同:he 学习的目的是“妹妹能用笔记”)
3、 与"so that"的区别
两者都可引导目的状语从句,但 "in order that" 更正式(多用于书面语),且强调“刻意性”;"so that" 更口语化,还可引导结果状语从句(此时不加情态动词)。
目的状语(同):She took notes in order that/so that she could review later.
结果状语(仅so that):She took notes, so that she remembered everything. (她记了笔记,结果记住了所有内容。)
4、 否定形式
若要表达“为了不……”,可在从句中加否定词 not,即 "in order that...not"。
He walked quietly in order that he might not wake the baby.
(他轻步走,以免吵醒宝宝。)
从句的主语可与主句一致或不一致:
一致:I practice English every day in order that I can improve. (我每天练英语,以便能进步。)
不一致:She bought extra food in order that her guests would have enough. (她多买了食物,以便客人有足够的吃的。)
情态动词的选择需符合语境:
could/might 更委婉,表“可能性”;will/would 表“意愿”或“预期”;can/may 更直接。
"in order that" 是正式的目的状语从句引导词,核心是“为了实现某个目的”,需接从句并常用情态动词。记住与 "in order to"(接不定式)、"so that"(更口语)的区别,就能准确使用啦!
